Learn exactly what to include when you request a quote for closed-loop attribution services-checklists, pricing ranges, RFQ template items, and US-focused timelines.
Share goals, revenue ranges, and data sources to accelerate accurate quotes.
Separate one-time setup from ongoing retainer and monitoring costs.
Provide sample exports so vendors can scope ETL and reconciliation precisely.
Closed-loop attribution connects paid media, site activity, and backend revenue data so you measure true return on ad spend and customer lifetime value. Requesting a quote for closed-loop attribution services helps you understand scope, cost, timeline, and the technical prerequisites required to build reliable, server-side attribution and data pipelines that prioritize profit over vanity metrics.
This process suits US-based eCommerce brands (Shopify, WooCommerce), B2B SaaS, and service businesses focused on CAC, LTV, and accurate MER. If you run multi-platform ads (Google, Meta, TikTok, LinkedIn) and rely on tools like GA4, Google Tag Manager, Stripe, or Klaviyo, a closed-loop project will materially improve decision-making.
If you need a reference for service scope and how we structure engagements, review our services overview at Prebo Digital services. To understand our approach and values, see our team background at About Prebo Digital.
| Line item | What it covers |
|---|---|
| Discovery & data audit | Inventory of ad accounts, events, server logs, and CRM integrations. |
| Tracking architecture | Server-side tagging, GTM configuration, event standardisation. |
| Attribution model & pipeline | Rules for matching conversions to touchpoints and ETL into analytics/BI. |
| Reporting & validation | Dashboards, reconciliation, and validation against P&L or order data. |
A clear quote separates fixed scope items (discovery, setup) from recurring items (retainer, monitoring, incremental reporting). When you request a quote for closed-loop attribution services, ask vendors to itemize which parts are one-time and which are ongoing.

Follow this checklist when you request a quote for closed-loop attribution services to speed up vendor responses and ensure apples-to-apples comparisons.
Include example questions in your RFQ such as: how will you match offline conversions to click-level data; what latency and data retention policies apply; which attribution models do you support; and how do you validate reconciled revenue against Shopify or the payment gateway?
Pricing varies by data complexity and scale. Typical engagements for US companies often fall into these ranges (estimates):
These ranges are provided for planning only; final quotes depend on required ETL, server-side infrastructure, and reporting complexity. If you'd like a practical example of implementation phases, see our structured approach on the homepage at Prebo Digital.
A thorough response will include a proposed timeline, deliverables per phase (Discovery → Build → Test → Scale → Report), a breakdown of one-time vs recurring fees, technical prerequisites, and a validation plan that ties back to revenue. For governance and long-term partnership details, review how agencies structure retainers in our services overview and where tracking expertise sits on the team at Contact Prebo Digital if you decide to request a formal proposal.
Practical tip: include a small sample of raw order exports (anonymized) and example ad-report exports when you request a quote for closed-loop attribution services. That lets vendors provide an accurate estimate rather than a wide range.
Typical timelines range from 4-8 weeks for basic closed-loop setups to 12+ weeks for multi-system ETL and custom attribution models. Expect discovery and scoping in week 1-2, implementation in weeks 3-8, and validation/reporting following go-live. For a focused growth audit or a custom eCommerce plan, many teams choose an initial fixed-price discovery, then move to a monthly retainer for scaling and monitoring.
If you want to compare vendor proposals efficiently, use the checklist above and request line-item pricing tied to deliverables and validation milestones.
