Requesting a Quote from a PPC Retainer Agency: What to Provide and What to Expect

Why a structured request matters when requesting a quote from a PPC retainer agency

Requesting a quote from a PPC retainer agency is more than asking for price ranges - it is the first step toward a measurable revenue partnership. Agencies price retainers based on scope, expected outcomes, tracking complexity, and the cleanup required to produce reliable attribution. If you’re a US-based founder, marketing director, or Shopify store owner, preparing a concise, data-driven brief reduces back-and-forth and produces more accurate proposals.

Key information to include in your initial brief

• Business model and vertical (eCommerce, B2B SaaS, services).
• Monthly media spend (last 3 months) and preferred platforms (Google Ads, Meta, TikTok, LinkedIn).
• Current tracking setup: GA4, server-side tagging, conversion windows, and known attribution gaps.
• Primary KPIs: revenue, MER, CAC, LTV targets, and margin constraints.
• Tech stack and access: Shopify/WooCommerce, payment processors (Stripe), CRM/ESP (Klaviyo, HubSpot), and analytics access scope.

Including this data upfront helps agencies scope work across strategy, tracking remediation, creative testing, and optimization cadence. For a template-driven start, agencies often ask for a short data export (CSV) showing monthly revenue vs media spend - sharing those numbers accelerates a realistic quote.

If you want to align the ask with a partner that uses a technical-first approach, see Prebo Digital’s services overview to confirm capabilities like server-side tracking and attribution-first reporting Services overview.

How agencies typically structure PPC retainers

Retainer models vary but commonly include some combination of fixed scope plus media management fees. Typical models are:

• Flat monthly retainer covering strategy, optimizations, and reporting.
• Tiered retainers based on media spend bands.
• Performance-aligned retainers with baseline fee plus variable bonus for revenue targets (designed to protect margins).

When requesting a quote, ask agencies to clarify what’s included (creative testing, landing pages, CRO, GA4 and server-side tagging) and what’s excluded (ad creative production costs, third-party tool subscriptions). Clear inclusions reduce scope creep and help you compare proposals apples-to-apples.

Initial questions to ask agencies when they respond

• How will you measure revenue and attribute conversions across platforms?
• What level of GA4 and server-side tagging cleanup is included?
• What reporting cadence and dashboards will you provide?
• How do you handle creative production and CRO?
• What does onboarding look like and how long until weekly optimization begins?

As you compile answers, track agency responses against the same brief. Agencies that emphasize attribution clarity, conversion tracking diagrams, and funnel optimization are easier to integrate into long-term growth plans.

A step-by-step checklist for requesting a quote from a PPC retainer agency

Use the checklist below when drafting your RFP or inquiry email. Include attachments or access notes where possible to allow agencies to run a quick diagnostic.

• Executive summary (50-150 words): business model, growth goal, and budget range.
• Performance snapshot: 3 months of spend and revenue, average order value (AOV), and conversion rate.
• Technical access: GA4, Google Ads/MCC, Meta Business Manager, Shopify/WooCommerce access levels.
• Priority workstreams: tracking cleanup, creative testing, landing-page CRO, and weekly optimizations.
• Timeline and decision criteria: proposal due date, interview windows, and expected start month.

Sample pricing expectations (US examples)

Pricing varies by complexity. These are example ranges for US-based eCommerce and service brands (estimates):

These ranges are illustrative; ask the agency for a breakdown showing hours allocated to strategy, tracking, creative testing, and reporting so you can compare cost-per-deliverable rather than headline price.

Funnel-based scope and deliverables

A structured proposal should map work to the funnel. Use TOF → MOF → BOF language when requesting the quote so scope aligns with measurable outcomes:

• TOF (Top of Funnel): audience expansion, prospecting campaigns, creative variants, CPM and reach metrics.
• MOF (Middle of Funnel): retargeting strategies, lead magnets, and nurture sequences tied to MQL/SQL movement.
• BOF (Bottom of Funnel): purchase optimization, checkout CRO, and accurate revenue attribution across touchpoints.

When agencies lay out tests per funnel stage and link each to a KPI (e.g., CAC, conversion rate, incremental revenue), you can evaluate their strategic thinking, not just their bidding tactics.

Compliance and tracking pitfalls to discuss up-front

In the United States, privacy controls and state laws like the CCPA affect signal availability and consent flows. Ask agencies how they handle cookie consent, hashed customer data, and server-side fallbacks to protect measurement accuracy while staying compliant.

Also request a sample onboarding timeline and expected milestones - for example: week 1 access, weeks 2-3 tracking remediation, week 4 launch optimizations.

Evaluating proposals and next steps

When proposals arrive, compare them on these axes: expected revenue impact, scope clarity, tracking fixes included, test roadmap, and reporting fidelity. Prioritize partners that propose measurable tests and clean attribution over those that focus only on traffic or click metrics.
