Server-side tracking

Deduplicate events and improve data fidelity across Google, Meta, and email channels.

Funnel-aligned testing

Design tests per TOF → MOF → BOF to prove incrementality and scale effectively.

Why cross-channel marketing orchestration matters in the United States

Cross-channel marketing orchestration coordinates paid search, social, display, email, and on-site experiences to move customers through a consistent funnel. Case studies on successful cross-channel marketing orchestration show measurable revenue lift when teams align messaging, data pipelines, and attribution. This article uses US-focused examples and practical tracking patterns to demonstrate how brands reduced CAC, improved LTV, and clarified attribution across platforms.

Key outcomes measured

Incremental revenue by channel and campaign
Attribution-adjusted CAC and MER (marketing efficiency ratio)
Conversion rate and funnel velocity across TOF → MOF → BOF

A modern orchestration stack (example)

A typical stack used in the case studies below: Google Ads + Meta Ads + TikTok (paid), Klaviyo or HubSpot (email), Shopify or WooCommerce (store), GA4 + server-side tracking + Google Tag Manager for clean attribution, and a CDP/ETL for unifying events. Prebo Digital's approach combines tracking and funnel optimization; for an overview of services and how we build these stacks see Services Overview.

Case study summary: mid-market D2C brand (US, $2-5M ARR)

Challenge: fragmented measurement across Facebook, Google, and email produced overstated platform conversions and unclear incremental spend. Solution: implement server-side tracking, consolidate events in GA4, and apply funnel-based attribution for TOF-driven prospecting versus BOF retargeting. Result: clearer channel-level incremental revenue and a 15-25% reduction in estimated CAC on prospecting channels (figures are illustrative and based on US market scenarios).

Consideration: reported platform conversions often double-count events when client-side signals and server-side events are not deduplicated. Server-side tagging with a policy for event priority reduces inflation and improves ROAS-to-reality alignment.

Funnel breakdown (TOF → MOF → BOF) - example metrics

Stage	Primary channels	KPIs (US example)
TOF	Display, Prospecting Search, TikTok	Impressions, CTR, New users, Cost per add-to-cart ($30-$70)
MOF	Paid social retargeting, Email nurturing	Engagement, Add-to-cart rate, Assisted conversions
BOF	Search remarketing, Dynamic product ads, Cart-abandon email	Conversion rate, AOV ($80-$150), CAC after attribution

For an applied perspective on how Prebo Digital assembles technical tracking and performance media together, see our company overview at Prebo Digital. The next section walks through two granular case examples and practical rules for testing and scaling.

Two granular case examples and tactical takeaways

Case example A - B2B SaaS demand orchestration (US-focused)

Scenario: a B2B SaaS with a $10k average contract value needed predictable lead volume without inflating lead quality. Orchestration: 1) align LinkedIn account-based campaigns with Google Search intent campaigns; 2) route clicks into a qualification flow tracked via GA4 and server-side events; 3) feed qualified leads into CRM with UTM-level revenue attribution. Outcome: clearer per-channel CAC and improved lead-to-paid conversion visibility - enabling smarter budget allocation between account-based and intent channels. Read more about performance-focused services similar to this model at About Prebo Digital.

Case example B - Shopify D2C scaling with orchestrated email and paid

Scenario: a Shopify store running multiple paid channels and layered email flows saw stagnating repeat purchase rates. Orchestration: unify first-party data with server-side events, model incrementality for email sends tied to paid campaigns, and test creative-tempo across TOF and remarketing. Example US outcome: a 6-12 week program showing a $1.15 incremental revenue per email send and higher ROAS when paid prospecting budgets were shifted to mid-funnel creative tests. For technical build and tracking guidance that supports this orchestration, see our services documentation at Services Overview.

Practical testing and scaling rules

Start with a hypothesis per channel: what role does each channel play in TOF → MOF → BOF?
Deduplicate server and client events with a unified ID strategy to avoid double counting.
Measure incrementality with holdout or geo-tests when possible; use modeling only when tests are infeasible.
Use MER and CAC built from first-party revenue signals rather than platform ROAS alone.

Common US compliance & privacy considerations

When implementing cross-channel orchestration in the United States, watch for CCPA implications around data collection and disclosure, and structure consent banners to allow essential tracking for attribution while honoring opt-outs. Server-side tracking can reduce client cookie reliance but must still respect user-level privacy controls.

How to read the results: attribution and revenue-first lenses

Interpret case study metrics through revenue-first lenses. For example, instead of saying "Channel A has 3x ROAS," report "Channel A drove $X incremental revenue and reduced blended CAC by Y%" - this aligns reporting to profitability and long-term value. If you want to explore how an attribution-first program is structured, our intake and project approach provides a repeatable framework; details are outlined on our contact page and project intake flow at Contact.

Checklist for replicating orchestration wins (US brands)

Map each channel to funnel stage and metric
Implement server-side tracking and consistent user IDs
Run incrementality tests or validated models
Prioritize revenue-based KPIs and MER adjustments

Sources

These case studies emphasize measurable orchestration: align channels to funnel roles, fix attribution at the data layer, and report against revenue-first KPIs. Applying these patterns across Shopify, WooCommerce, B2B SaaS, and enterprise retail in the United States improves clarity and supports scalable budget decisions.

Digital Marketing for Online Retailers: What Actually Drives Profitable Revenue

Online Retail Growth Myths That Quietly Destroy Margin Most online retailers do not have a traffic problem. They have a conversion and attribution problem disguised as a traffic problem. When revenue stalls, the instinct is to buy more clicks. But for a store doing 100,000 monthly sessions at a 1.2% conversion rate with a $65 average order value, the math is unforgiving: that is roughly ZAR 78,000 in revenue (about USD 4,300 at prevailing exchange rates). Lift the same traffic to a 1.8% conversion rate and revenue becomes roughly ZAR 117,000-a near 50% jump with zero additional ad spend . ~50% Revenue lift from CVR improvement alone, holding sessions constant Myth 1 - More Sessions Means More Revenue Sessions are an input, not an outcome. Google Analytics 4 will happily show a 20% traffic increase while revenue stays flat because the new sessions land on low-intent pages, bounce on a slow mobile PDP, or hit a checkout with unexpected shipping costs. US retailers competing across state lines also face brutal seasonality-holiday traffic spikes mask weak conversion mechanics the rest of the year. The counter-move is to treat CRO as a paid channel with its own ROI. Fixing a product page, adding trust signals for first-time US buyers, and tightening mobile checkout routinely outperforms a 15% budget increase on Meta. Myth 2 - Platform-Reported ROAS Is Your Real ROAS Inside Ads Manager, Meta reports its own attributed purchases. Inside Google Ads, Google does the same. Add them together and you often get a number that exceeds total store revenue-a mathematical impossibility your CFO will notice. This is the documented territory where platform-reported ROAS inflates the real picture, often by 20-40%, once you account for overlap, view-through windows, and modelled conversions. Warning: If Meta + Google reported conversions sum to more than your Shopify order count, your attribution is double-counting. Fix the measurement layer before scaling spend. Myth 3 - Email and SMS Are Legacy Channels For US DTC brands, Klaviyo-driven flows typically account for a meaningful share of total revenue at the highest contribution margin of any channel-there is no media cost per send. Abandoned checkout, browse abandonment, and post-purchase flows compound while you sleep. Treating email as a quarterly newsletter rather than an automated revenue system is one of the most expensive habits in online retail. The One Calculation Every Online Retailer Should Run Weekly Reported ROAS is a channel-level vanity number. MER (Marketing Efficiency Ratio) and contribution margin are business-level truths. Run both weekly, not quarterly. MER = Total Revenue / Total Ad Spend Contribution Margin (CM) = Revenue - COGS - Shipping & Fulfilment - Payment Processing Fees - Total Ad Spend Blended CAC = Total Ad Spend / New Customers MER vs ROAS vs Contribution Margin - What Each Number Actually Tells You ROAS tells you what a single platform claims. MER tells you whether the whole business is efficient. Contribution margin tells you whether you are actually making money after the cost of goods, shipping, and payment fees-the costs Stripe and Shopify pass through quietly. A store can run at 4.0 platform ROAS and still lose money if contribution margin is negative. That is the number that decides whether you scale or pause. Why iOS, Cookie Consent, and CCPA Break Platform Numbers Apple's App Tracking Transparency reduced pixel signal fidelity for iOS users-a large share of US mobile commerce traffic. Browser restrictions on third-party cookies and US state privacy laws including CCPA/CPRA mean a portion of users never consent to tracking. If your tags fire only after consent and you have no server-side fallback, you are optimising algorithms on a partial dataset, and the algorithm fills the gap with modelled guesses that rarely match your bank account. Info: Consent Mode and CCPA/CPRA compliance are operational requirements, not optional enhancements. They shape every downstream conversion number you use to make budget decisions. What the US Retail Stack Looks Like When It Works Together A working US retail stack is not a list of tools. It is a data flow: Shopify or WooCommerce captures the order; Stripe confirms payment; GA4 receives consented events; Klaviyo triggers lifecycle messaging; and the ad platforms receive server-side signals for optimisation. When any link in that chain breaks, every downstream number lies. Shopify, Klaviyo, GA4, and Stripe - Where Attribution Usually Breaks Duplicate purchase events: A checkout pixel plus a thank-you page pixel count the same order twice, inflating conversion volume. Missing server-side events: Browser-only tracking loses orders when the tab closes or ad blockers intervene. Klaviyo and platform overlap: Email-attributed revenue also shows up in Meta's view-through window, inflating both channels. Stripe fees invisible to GA4: ROAS looks healthy while contribution margin is being eaten by processor fees and refunds. Server-Side Tagging and Conversions API: The Non-Negotiable Fix Server-side Google Tag Manager and Meta's Conversions API move event delivery off the browser and onto a controlled server container. For US retailers, this means more resilient signal through iOS restrictions, cleaner deduplication, and the ability to include consented first-party data that browsers would otherwise strip. Teams that implement this correctly often see attributed revenue rise simply because previously invisible orders are now counted-and the algorithms get better data to optimise against. Tip: Validate server-side events against Shopify order counts weekly. If GA4 purchases and Shopify orders diverge by more than a few percent, diagnose before scaling. Channel Roles, Not Channel Rankings Stop asking which channel is "best." Ask what job each channel does in the funnel and what KPI measures that job. A channel judged on the wrong KPI will always look like a failure. Mapping Google Search, Meta, Email, SEO, and TikTok to Funnel Stages Channel Funnel Stage Primary KPI Typical US Budget Range (est.) Google Search (brand + non-brand) BOF / high intent Blended CAC, CM USD 3k-40k+/mo Meta (Advantage+) TOF / MOF New customer CAC USD 5k-60k+/mo Klaviyo email/SMS MOF / retention Revenue per recipient, LTV USD 300-2k/mo tooling SEO / content TOF / MOF Non-brand organic revenue USD 2k-15k/mo TikTok TOF demand-gen Hook rate, assisted revenue USD 3k-25k+/mo Why High-Intent and Demand-Gen Channels Need Different KPI Sets Google Search catches people already looking for your product-judge it on efficiency (CAC, CM). Meta and TikTok create demand-judge them on new-customer acquisition and assisted revenue, not last-click ROAS. Email monetises the list you already own-judge it on LTV and repeat purchase rate. Applying a single KPI across all channels is how retailers kill the channels that were actually growing the business.

International Shipping Services for eCommerce: 5 Myths Costing You Margin

Why International Shipping Services Break eCommerce Margin (Not Just Logistics) Cross-border shipping gets filed under "operations" in most US brands - a cost line next to warehousing and 3PL fees. That framing is why it quietly erodes contribution margin. International shipping services touch three P&L levers simultaneously: landed cost (your COGS on exported orders), conversion rate (shipping speed and duty transparency at checkout), and attribution (whether the sale even registers correctly in GA4). A brand doing US$500,000 monthly revenue at 20% cross-border mix is moving roughly US$100,000 through carriers, brokers, and customs regimes that behave nothing like UPS Ground domestically. For a scaling DTC brand, a 6-point swing in cross-border contribution margin is worth more than most paid-media efficiency projects. The five myths below account for the majority of that swing. ~20% Typical cross-border share of revenue for US DTC brands selling into Canada, the UK, and the EU (estimate - varies heavily by category) Myth 1: The Buyer Always Pays Import Duties This is the most expensive misconception in cross-border eCommerce, and it usually originates on the checkout page. If your store advertises "duties calculated at delivery" or "taxes may apply on arrival," you have implicitly chosen an Incoterm - often DAP (Delivered At Place) - whether or not anyone in your organisation has read the term. Fact: Incoterms 2020 Determines Who Is the Importer of Record The Incoterms 2020 rules published by the International Chamber of Commerce define the commercial terms that decide who clears goods and who pays duty. Four terms matter for eCommerce sellers: Incoterm Who Pays Duty & Import Tax eCommerce Impact DDP Seller (you are importer of record in many jurisdictions) Cleanest CX; you absorb duty, brokerage, and refund risk DAP Buyer, on delivery High refusal and chargeback rate; angry post-purchase support tickets FCA Buyer from named place onward Common for B2B export; rarely appropriate for DTC EXW Buyer from your dock Maximum risk transfer; almost never a DTC default Warning: Under DDP you can become the importer of record in the destination country. That means duty liability, customs penalties for misclassification, and VAT registration obligations may sit with your entity - not your customer's. Confirm the structure with a customs broker or trade lawyer before you default to DDP globally. Myth 2: "Free International Shipping" Is Just a Pricing Decision Free shipping worked domestically because you could forecast it to the dollar. Cross-border, the "free" label often hides a landed cost you never modelled. Fact: Landed Cost Has Four Components Domestic Shipping Doesn't Domestic shipping cost = carrier rate + packaging. Cross-border landed cost adds four stacks: Duty - a percentage of customs value, set by your HS code and the destination's tariff schedule Import tax / VAT - e.g. UK VAT at 20% on most goods, EU VAT varying by member state Clearance / brokerage fee - typically US$10-US$45 per shipment depending on carrier and broker Last-mile local-carrier charge - the domestic delivery leg billed at foreign rates Example (estimate): a US$120 apparel order shipped to Germany. Duty at a representative 12% is US$14.40, German VAT at 19% applies to the duty-inclusive value, brokerage is roughly US$20, and last-mile adds US$8. Your "free shipping" promise on a US$120 order can consume ZAR-equivalent (roughly US$55) of margin before the ad spend is even counted. Tip: Showing an all-in landed cost at checkout - duty and tax included - consistently reduces cart abandonment on cross-border orders because it removes the post-purchase surprise. Treat it as a CRO test, not an accounting exercise. Myth 3: Customs Delays Are Random Fact: Most Holds Trace to Documentation, Not Enforcement When a shipment sits in customs for five days, the instinct is "bad luck." In practice, the leading causes are self-inflicted: an incorrect or generic HS code, a commercial invoice that doesn't match the manifest value, a missing country-of-origin declaration, or a vague product description ("gift," "sample," "accessories"). HS codes are administered globally by the World Customs Organization , while the US-specific schedule is maintained by the US International Trade Commission's Harmonized Tariff Schedule . Misclassification is the single most common customs-hold trigger - and it is a data problem, not a logistics problem. What De Minimis Thresholds Actually Are (and Why They Vary So Much) A de minimis threshold is the order value below which duty (and sometimes tax) is waived. It exists because collecting small duty amounts costs more than the revenue they generate. Each jurisdiction sets its own number. US Section 321, EU IOSS, and UK VAT: A Threshold Comparison Table Market Threshold Mechanism Notes United States US$800 per shipment Section 321 (de minimis) Applied per shipment, per day, per importer. Legislative proposals have repeatedly sought to lower or remove it - verify current status before planning around it. European Union EUR 150 (goods value) IOSS for VAT collection VAT is due from EUR 0; IOSS lets you collect it at checkout instead of on delivery. United Kingdom GBP 135 (goods value) VAT collected at point of sale for consignments up to GBP 135 Duty applies above GBP 135; VAT generally applies from GBP 0. Info: The US$800 US figure is current at time of writing. It has been the target of repeated legislative proposals, so treat it as a planning assumption with a review date, not a permanent fixture of your pricing model. Why This Matters to Marketing, Not Just Ops Every myth above produces the same downstream symptom: unreliable contribution data. If you cannot state the true landed cost of a cross-border order, you cannot compute a defensible CAC ceiling for that market - and your blended MER becomes fiction.

eCommerce Shipping Solutions: Build vs Buy vs Outsource (US Guide)

Five Shipping Myths That Quietly Erode US eCommerce Margins Shipping is often treated as a back-office line item, but for US eCommerce brands it drives conversion rate, average order value (AOV), marketing efficiency ratio (MER), and repeat purchase. At Prebo Digital , we consistently see shipping decisions downstream of clean attribution: when shipping events are missing from GA4 and server-side pipelines, teams cannot connect fulfillment choices to revenue. The following five myths are common in mid-market US stores and each one has a measurable cost. Myth 1: "Free Shipping Is Always the Answer" Free shipping can lift conversion, but it is not free. Baymard Institute’s cart-abandonment research consistently finds that “extra costs too high (shipping, tax, fees)” is the top reason US shoppers abandon checkout - the live figure typically hovers around 48%. The knee-jerk response is to blanket-offer free shipping, which immediately compresses contribution margin. A more disciplined approach is a threshold test: set free shipping at a cart value that lifts AOV enough to cover the incremental shipping cost. For example, a brand with a ZAR 750 average order might test a ZAR 1,200 free-shipping threshold and measure whether the AOV lift outweighs the added fulfillment expense. Warning: Blanket free shipping without a threshold or margin model is one of the fastest ways to erode MER during peak season. Always model landed cost before committing. Myth 2: "The Cheapest Label Wins" Carrier selection is not a single-variable decision. A cheaper base rate can be wiped out by dimensional (DIM) weight penalties, residential surcharges, peak-season surcharges, and zone jumps. UPS and FedEx announce general rate increases (GRI) effective late December or early January, and both apply peak surcharges during the holiday window. USPS Ground Advantage replaced First-Class Package and Retail Ground in 2023, changing the economics for lightweight parcels. The real comparison is landed cost per delivered order, not the label price at checkout. ~48% of US shoppers cite extra costs (shipping, tax, fees) as the top reason they abandon checkout - Baymard Institute Myth 3: "Shipping Is an Ops Problem, Not a Marketing Problem" Shipping method selection changes checkout conversion, AOV, and repeat purchase. If your paid media team cannot see shipping cost per order alongside CAC, they cannot optimise profitably. Instrumenting shipping events in GA4 and server-side pipelines connects fulfillment to acquisition. Prebo Digital’s services include server-side tracking and analytics engineering that make this connection possible. Myth 4: "Once You Pick a Carrier or 3PL, You Are Locked In" Most multi-carrier software and 3PL contracts allow you to add or change carriers with reasonable notice. The lock-in is usually data, not contracts. If your shipping data lives in a spreadsheet or a 3PL portal that does not export cleanly, switching becomes painful. Choose solutions that expose APIs and webhooks so you can move when economics change. Myth 5: "Tracking Ends at the Tracking Number" The tracking number is the beginning of the post-purchase experience, not the end. Delivery exceptions, delays, and returns drive WISMO (“where is my order?”) tickets and refunds. Feeding carrier webhooks into Klaviyo flows for proactive updates reduces support load and protects repeat purchase. National Retail Federation research on consumer returns shows return rates commonly cited between 15% and 30% depending on category, with apparel highest. Ignoring the post-purchase data loop means you are flying blind on a major cost centre. What Shipping Actually Costs: Landed Cost, DIM Weight, and Surcharges Landed cost per order is the sum of carrier base rate, fuel surcharge, residential or delivery-area surcharge, peak surcharge where applicable, DIM weight penalty, packaging, labour, and expected return cost. Many US brands track only the label cost and are surprised when quarterly fulfillment spend overshoots. The table below outlines the components we see most often. Cost Component Typical US Impact Where It Hides DIM weight penalty Can add 20-40% to lightweight, bulky parcels Carrier invoice line items Residential/delivery-area surcharge Fixed per-parcel fee, varies by carrier Carrier rate cards Peak surcharge Applies Oct-Jan on UPS, FedEx, and some USPS services Seasonal invoices Return cost 15-30% of orders depending on category P&L, often unallocated How to Calculate Dimensional Weight Before It Hits Your P&L Carriers bill on the greater of actual weight and DIM weight. The formula is length × width × height divided by a dimensional divisor. UPS and FedEx daily rates commonly use 139; some USPS services use 166. Always verify current divisors with the carrier. The code block below shows the calculation. # DIM weight calculation example (inches, pounds) length = 18 width = 14 height = 8 divisor = 139 # UPS/FedEx daily rates; some USPS services use 166 dim_weight = (length * width * height) / divisor print(f"DIM weight: {dim_weight:.2f} lbs") # Output: DIM weight: 14.50 lbs actual_weight = 6.0 billed_weight = max(actual_weight, dim_weight) print(f"Billed weight: {billed_weight:.2f} lbs") # Output: Billed weight: 14.50 lbs If your packaging allows a parcel to be reduced from 18×14×8 to 16×12×6, DIM weight drops to roughly 8.29 lbs, which can shift the parcel into a lower rate tier. This is where packaging engineering meets margin protection. Tip: Run a sample of 20 recent orders through the DIM formula before your next carrier negotiation. You will often find a packaging change that reduces billed weight without compromising protection. The Three Shipping Solution Paths: Build, Buy, or Outsource US eCommerce brands generally choose one of three paths. Each has a different cost structure, control profile, and data accessibility. The table below summarises the trade-offs. Path Best For Control Data Access Build (direct carrier accounts) Brands with negotiated rates and in-house warehouse Highest Full API/webhook access Buy (multi-carrier software) Brands wanting rate-shopping without volume commitments Medium Good if API-enabled Outsource (3PL) High-volume or peak-heavy brands needing surge capacity Lower Varies by 3PL Build: Direct Carrier Accounts and Your Own Warehouse Direct accounts with UPS, FedEx, and USPS can deliver the best rates at volume, but they require negotiated contracts, EDI or API integration, and in-house labour. This path suits brands with predictable volume and a warehouse team. Buy: Multi-Carrier Software and Rate-Shopping APIs ShipStation, Shippo, EasyPost, Pirate Ship, and Shopify Shipping provide discounted rates and rate-shopping across carriers without contract negotiations. The trade-off is a per-label or subscription fee. These platforms often expose webhooks that make GA4 and server-side instrumentation straightforward. Outsource: 3PL and Fulfillment Partners 3PLs such as ShipBob handle storage, pick, pack, and ship, often with negotiated carrier rates. They are attractive during peak season when in-house capacity is stretched. The key evaluation criteria are data export capability, rate transparency, and surge pricing. Info: A common rule of thumb is that below a few hundred orders per month, in-house fulfillment with discounted-rate software usually wins on cost and control; above that range, 3PL labour and negotiated rates can become competitive. Treat this as a range, not a guarantee.

How-to-Measure-Online-Marketplace-Optimization-Success: A Practical Guide

Why measuring marketplace optimization success matters If you run product listings on Amazon, eBay, Etsy, Walmart Marketplace or similar channels, measuring optimization success lets you move beyond impressions and star ratings to decisions that improve revenue, reduce CAC, and lengthen customer lifetime value (LTV). This guide explains how-to-measure-online-marketplace-optimization-success with tracking approaches, funnel breakdowns, and practical US-focused examples tied to Shopify and common payment flows. Define the right success metrics Start with a small set of business-centric KPIs that reflect profitability and attribution accuracy, not vanity metrics. Typical KPIs include: Revenue by SKU and channel (use $ for US dollars) Conversion rate (detail page to purchase) Return on ad spend (ROAS) measured with clean attribution Customer acquisition cost (CAC) and first-order margin Repeat-purchase rate and 30/90-day LTV Map the marketplace funnel (TOF → MOF → BOF) Break the buyer journey into top, middle, and bottom funnel events so you can attribute tests to revenue. Example funnel for a marketplace listing: TOF: Listing impressions, search term visibility, click-through rate (CTR) MOF: Detail page engagement (images viewed, buy box share, reviews read) BOF: Add-to-cart, purchase, post-purchase retention Tracking each stage lets you run experiments that target the rate-limiting step (e.g., improving buy box win rate versus improving product images). Core tracking stack and data sources A reliable measurement stack mixes platform-level reports and first-party data. For US sellers this typically includes marketplace analytics, server-side event capture, and centralized analytics like GA4 or a data warehouse. Marketplace native reporting (Amazon, eBay, Etsy dashboards) Server-side order receipts (Shopify/WooCommerce webhooks) to capture true conversions and margins GA4 or a measurement tool for cross-channel session stitching and marketing channel performance For data hygiene, use server-side tracking and deduplicated events to avoid double-counting platform-reported conversions. If you use Shopify, combining transaction webhooks with marketplace order reports clarifies fulfillment and fees. Tip: When measuring US marketplace performance, always express financial KPIs in $ and include marketplace fees and shipping in CAC and margin calculations.
