Requesting a Quote from a Performance Marketing Agency: A Practical US Guide

What to expect when requesting a quote from a performance marketing agency

When you are requesting a quote from a performance marketing agency, expect the process to be diagnostic-first: agencies will assess your current funnels, tracking fidelity, and unit economics before sizing scope and cost. A strong proposal ties channels to revenue outcomes (CAC, LTV, MER), not just clicks or impressions. This guide explains the inputs agencies need, common pricing models, and how to compare apples-to-apples proposals for US-based eCommerce and B2B businesses.

Core inputs agencies will request

• Monthly ad spend by channel (Google, Meta, TikTok, LinkedIn) and historical ROAS or LTV/CAC figures.
• Access to analytics and ad accounts (GA4 property, Google Ads, Meta Business Manager) or a tracking export.
• Conversion definitions and attribution windows you use for reporting.
• Product margins, average order value (AOV), and repeat purchase rates (for eCommerce).

Common pricing structures

Agencies typically price one of three ways: a flat monthly retainer for strategy and execution, a percentage of ad spend (managed spend fee), or a blended performance fee tied to measured milestones. For US clients, clarify whether the quote includes media spend, creative production, and tracking setup. Ask for pricing shown in US$ and whether taxes or third-party costs are excluded.

Sample quote line items (what to request)

When requesting a quote, ask agencies to break out line items so you can compare scope. Typical items include:

• Discovery and measurement audit (one-time).
• GA4, Google Tag Manager, and server-side tracking setup (one-time).
• Campaign build and launch by channel (one-time or phased).
• Ongoing media management and optimization (monthly retainer).
• Creative production and testing (per asset or monthly).
• Reporting, dashboards, and data engineering (monthly).

These are estimates and can vary by agency expertise, channel complexity, and data engineering needs. If you want a faster starting point, Prebo Digital’s Services Overview details typical engagements and channel specializations on the agency side: Services Overview.

What you should provide with your request

• Clear business goals (target CAC, growth rate, MER) expressed in US$ when possible.
• Access windows for analytics and ad accounts or sample CSV exports.
• Creative assets and product catalog access (Shopify or WooCommerce) for ad readiness.
• Preferred reporting cadence and KPIs.

Evaluating and comparing quotes

When you receive multiple proposals after requesting a quote from a performance marketing agency, compare them on scope, measurement clarity, and expected revenue impact. Don’t default to the lowest headline price-prioritize proposals that show how they will protect attribution accuracy (server-side tracking, conversion modeling) and how they measure incremental revenue.

Side-by-side checklist

• Does the quote include a GA4 and server-side tracking plan?
• Are deliverables timeboxed with milestones and acceptance criteria?
• Is reporting tied to revenue (MER or validated LTV) rather than platform conversions only?
• Is there a clear testing roadmap (CRO, creative A/B tests) to improve unit economics?

Example US scenario

A mid-market Shopify store with $50,000/month ad spend requests a quote to reduce CAC from $60 to $45 while maintaining ROAS. An agency proposal that includes a $6,000 monthly retainer plus a $2,500 one-time tracking audit may show a path: measurement fixes (server-side), channel redistribution, and CRO tests. Estimates like these should be labelled as projected ranges and reassessed after a 60-90 day test window.

Negotiation and scope control

Negotiate clear acceptance criteria for deliverables and an initial 90-day pilot with defined checkpoints. Ask for a breakdown of what is excluded (e.g., media budgets, third-party creative vendors) and whether reporting will include raw event exports or just dashboards. For agency experience and team fit, review the About page to confirm approach and core services alignment: About Prebo Digital.

When to proceed

Proceed when a quote demonstrates measurable milestones (first 30/60/90 days), clear attribution improvements, and projected impact on CAC or MER.

Measurement and reporting expectations

Ensure the contract specifies reporting frequency, data exports, and reconciliation methods between platform-reported conversions and attributed revenue. For many US merchants, server-side tracking plus modeled conversions reduces variance and improves pacing. Ask vendors how they will validate results against your payment provider (Stripe, Shopify Payments) and how often they will update attribution windows.
