You just signed with an Amazon agency. The kickoff call went well. You're excited. Now what?

Most brands enter amazon agency onboarding with vague expectations. They know the agency will "handle Amazon," but they don't know what that looks like day to day, what decisions they'll face, or when results should start appearing. Some agencies keep this intentionally opaque. Good ones don't.

This timeline walks through what actually happens in your first 90 days with an Amazon agency, broken into three phases: Audit and Discovery (Days 1-30), Building and Launching (Days 31-60), and Optimization and Early Results (Days 61-90). It's written from the brand's perspective, so you know what to expect, what to prepare, and how to spot when things aren't moving fast enough.

Before Day 1: What to Prepare Before Your Agency Kicks Off

The best onboardings start before the official kickoff. Here's what you can do now to avoid delays later.

Access and Permissions Checklist

Your agency needs specific access to do their job. The faster you grant it, the faster they can start working. At minimum, set up:

Seller Central user account with the right permission sets. Most agencies need: Inventory, Pricing, Advertising, Reports, Brand, and Account Health. Some also need Messaging (if they're handling customer service) and Tax (if they're advising on sales tax compliance).

Amazon Advertising Console access. This is separate from Seller Central. If your agency is managing PPC, they need direct access to the ad console, not just a user account with "view advertising" permissions.

Brand Registry authorization. If your brand is enrolled in Amazon Brand Registry, your agency needs authorization to access A+ Content, Brand Analytics, Brand Stores, and other brand tools. This requires you to add them as an authorized user through the Brand Registry portal.

Amazon DSP seat access (if DSP is in scope). Display and video advertising through Amazon DSP requires separate access. If your contract includes DSP, coordinate this with your account manager.

Granting access before day 1 means your agency can start the audit immediately instead of spending week one chasing permissions.

Goals and KPIs Worth Defining Upfront

You hired an agency for a reason. Define that reason before kickoff. Are you trying to:

• Scale revenue while maintaining profitability?
• Fix underperforming listings that have potential?
• Launch new products in a competitive category?
• Reduce reliance on paid traffic and grow organic share?

Your agency should ask these questions during the sales process. If they didn't, bring them to the kickoff call. The clearer you are about what success looks like, the better the strategy will align with your goals.

Days 1-30: The Audit and Discovery Phase

The first 30 days look slow from the outside. No major changes are happening yet. Your listings haven't been rewritten. Your advertising spend might not have changed. But this phase is where the agency is building the foundation.

Account Audit: What Your Agency Is Looking At

A real audit goes beyond "everything looks good" or "we found some issues." Your agency should present findings in these areas:

Account health. Are there suppression flags, policy violations, return rate problems, or customer feedback trends that need attention? These block optimization work if left unaddressed.

Listing quality. How do your titles, bullet points, backend keywords, images, and A+ Content compare to category standards? Is your content indexed for the keywords that matter? Are you missing required attributes?

Advertising performance. What's your current campaign structure? Which keywords are wasting spend? Where are the gaps in targeting? What's the trend in ACOS and conversion rate over the past 90 days?

Storefront presence. If you have a Brand Store, how's the layout? Are pages driving traffic and conversions, or do visitors bounce? Is the navigation clear?

Inventory and operations. Are you dealing with stranded inventory, low-stock alerts, or fee optimization opportunities? How's your FBA health score?

Within the first 2-4 weeks, you should receive a structured audit document. This could be a slide deck, a detailed report, or a live walkthrough. The format matters less than the specificity. If the audit reads like it could apply to any brand, it's not thorough enough.

Competitive Analysis and Category Benchmarking

Your agency should also be analyzing your category dynamics. This includes:

• Who are your top 5 competitors by sales rank and share of voice?
• How does your pricing compare?
• How does your content (images, A+, reviews) stack up?
• What advertising strategies are competitors using?
• What's the traffic and conversion benchmark for your category?

This isn't just interesting data. It shapes the strategy. If your competitors are running high-traffic, low-margin PPC strategies, your approach should be different. If the category is image-driven and your photography is weak, that's a priority fix.

The Strategy Presentation: What You Should Expect to See

By day 25-30, your agency should present a strategy document. This is where they translate the audit findings into a plan. A good strategy presentation includes:

Prioritized action items. Not everything can happen at once. What gets fixed first, and why?

Category-specific context. If the plan could apply to any brand in any vertical, it's not tailored enough. The strategy should reference your specific competitors, your product's positioning, and your category's pricing and advertising dynamics.

Realistic timelines. When will listings be updated? When do new campaigns launch? When should you expect to see performance shifts?

Roles and responsibilities. What's the agency handling? What do you need to approve? What does your team need to provide (images, copy input, product roadmap)?

Budget and spend assumptions. If the strategy relies on scaling ad spend, what's the ramp plan? What's the expected return?

If the strategy presentation feels generic or rushed, push back. This document becomes the roadmap for the next 60 days. It should be specific, defensible, and grounded in the audit data.

If you're evaluating whether an Amazon agency partnership is the right model for your brand, the strategy phase is where that becomes clear.

Days 31-60: Building and Launching

This is when the agency starts executing. You'll see changes go live, new campaigns launch, and the first signs of movement in your data. But it's still too early for meaningful results.

Listing Optimization and Content Overhaul

If your audit identified weak content, month two is when the rewrites happen. Expect the agency to:

• Rewrite titles, bullets, and product descriptions based on keyword research and conversion best practices
• Update backend search terms to maximize indexing for relevant queries
• Build or refresh A+ Content modules with better imagery, comparison charts, and product storytelling
• Recommend new photography or video if existing assets are outdated or low-quality

You'll need to approve these changes before they go live. Review them carefully. The agency should explain why they're making each change (keyword targeting, conversion optimization, competitive parity). If they can't explain the rationale, ask.

Advertising Strategy and Campaign Architecture

New campaigns typically launch between days 35-50. Your agency should build a structured campaign architecture, which might include:

Auto campaigns to harvest keyword data and discover new search terms converting for your products.

Manual exact and phrase campaigns targeting high-intent keywords based on the audit and competitive research.

Product targeting campaigns to place your ads on competitor detail pages and complementary products.

Category and audience targeting using Sponsored Display to retarget shoppers who viewed your products or similar items.

Early performance will look messy. ACOS will likely be higher than target. Impression share might be low while campaigns ramp. This is expected. The agency is running a controlled test to see what works before scaling spend.

If your agency launches campaigns and immediately claims success based on week one data, they're overselling. Week one is noise.

Storefront Build or Refresh

If you don't have an Amazon Brand Store, month two is when it gets built. If you already have one, the agency may recommend a redesign based on:

• Traffic and conversion data showing which pages are underperforming
• Category best practices for layout and navigation
• Product bundling and cross-sell opportunities

Storefront work often gets deprioritized, but it shouldn't. A well-designed Brand Store improves conversion rates, increases average order value, and gives you a defensible brand presence off the detail page.

Amazon Storefront strategy and structure should align with your broader brand positioning.

Supply Chain and Inventory Review

If your agency handles supply chain planning, they'll be analyzing:

• Restock recommendations to avoid stockouts during the optimization ramp
• Inbound placement fee impact (Amazon's 2025/2026 fee structure makes this a bigger deal than it used to be)
• Low-inventory fee exposure
• Seasonal demand patterns that should inform restocking timing

This isn't glamorous work, but it matters. Running out of stock during the ramp kills momentum. Having excess inventory sitting in expensive fulfillment centers eats into margin.

Amazon supply chain management is often the difference between scaling profitably and scaling into a cash crunch.

Days 61-90: Optimization and Early Results

Month three is when you start seeing trend-level data. Campaigns have been running long enough to move past the learning phase. Listings have been live long enough to affect organic rank. Your agency should be shifting from "build" mode to "refine and scale" mode.

PPC Learning Phase: Why ACOS Looks Weird at First

If your ACOS spiked in weeks 4-6, that's normal. New campaigns need time to learn which placements and keywords convert. Amazon's bidding algorithm doesn't have enough data to bid efficiently until 2-4 weeks in.

By day 60, your agency should be:

• Pausing or reducing bids on keywords and placements that aren't converting
• Increasing bids on high-performing search terms to capture more traffic
• Harvesting search term data from auto campaigns and adding top performers to manual campaigns
• Testing bid strategies (dynamic bids down only, dynamic bids up and down, fixed bids) to find what works for your products

ACOS should start trending down between days 60-75. If it's still climbing or flat, your agency should explain why and what they're adjusting.

Organic Ranking Movement and What to Watch

Listing changes and increased traffic from PPC should start affecting organic rank. Track these metrics:

• Best Seller Rank (BSR) trend over the past 30 days
• Keyword rank movement for your priority search terms
• Organic session percentage (what % of your total traffic is organic vs. paid?)

Rank movement is slow. A product that was ranking #45 for a key term on day 30 might move to #30 by day 75. That's progress, even if it doesn't feel dramatic. The agency should show you before/after rank data and explain what's driving movement (better content, more reviews, increased conversion rate from PPC traffic).

Building Amazon product reviews velocity is part of the long game. Expect the agency to recommend Vine enrollment or review request automation during this phase.

Reporting Cadence: What Good Reporting Looks Like

By day 90, you should have seen at least two structured performance reviews. A good report includes:

Performance vs. target. How does actual ACOS, revenue, conversion rate, and traffic compare to the goals set during the strategy phase?

Trend analysis, not just snapshots. A single week's data means nothing. The report should show 30-day trends and compare current performance to the baseline (pre-agency).

Explanations for anomalies. If ACOS spiked in week 8, why? If organic traffic dropped in week 10, what happened? The agency should proactively explain variance, not wait for you to ask.

Next 30 days priorities. What's changing in the next month? What tests are launching? What optimizations are planned?

If your agency sends spreadsheet dumps with no context, that's a problem. Data without interpretation isn't reporting.

Course Corrections Based on Real Data

The strategy from day 30 was a hypothesis. By day 90, the agency has real performance data. Expect them to adjust:

• Budget allocation across campaigns based on what's actually working
• Product prioritization (some SKUs might be outperforming expectations; others might need more work)
• Content iteration (if certain A+ modules or images are driving higher engagement, double down)
• Keyword targeting refinement (the initial keyword list was educated guesswork; now there's conversion data to guide decisions)

Agencies that stick rigidly to the original plan regardless of performance aren't optimizing. The best agencies treat the first 90 days as a discovery process and adjust strategy based on what they learn.

Red Flags: Signs Your Agency Isn't Moving Fast Enough

Most brands don't know what "normal" looks like during amazon agency onboarding. Here's how to spot when your agency is underperforming.

What to Expect After 90 Days

Day 90 isn't an endpoint. It's the end of the onboarding phase and the start of continuous optimization. Here's what should happen next.

Setting the Next Quarter's Goals

Your agency should present a Q2 roadmap based on the first 90 days of data. This might include:

• Scaling spend on campaigns that hit target ACOS
• Launching new products identified during the onboarding audit
• Testing different creative (images, video, A+ layouts) to improve conversion rate
• Expanding into new ad formats (Sponsored TV, DSP retargeting) if the foundational campaigns are performing

The goals should be more aggressive than Q1 because the learning phase is over. If your agency recommends "staying the course" without pushing into new tests or scale opportunities, they're being too cautious.

Scaling Advertising Spend Based on Performance

If campaigns are hitting target ACOS and there's room to grow impression share, Q2 is when spend should ramp. Your agency should present a scaling plan that includes:

• Budget increases tied to specific campaigns and products
• Expected return based on current performance trends
• Guardrails (max ACOS, minimum ROAS, daily budget caps) to manage risk

Scaling too fast kills profitability. Scaling too slow leaves revenue on the table. A good agency finds the balance.

When to Start Seeing ROI

This depends on your baseline and goals, but general benchmarks:

ROI isn't just revenue. It's also time saved, expertise accessed, and mistakes avoided. If your agency is handling listing compliance, advertising optimization, and supply chain planning, calculate the cost of doing that in-house (salary, tools, learning curve, opportunity cost). That's part of the ROI equation.

SupplyKick's Amazon agency partnership model is designed for brands that want operational expertise without giving up brand control.
