Launching a DTC/Shopify Brand on Amazon: A 90-Day Plan

If you already sell through Shopify or your own DTC website, launching on Amazon isn't as simple as copying your product page and uploading it.

Amazon is a completely different sales channel. Costs, search behavior, fulfillment rules, catalog setup, the review system, and available data all differ.

That is why your first 90 days should focus on getting ready, launching carefully, and using real data to make decisions. You should not expect guaranteed rankings, reviews, sales, or profits within a fixed number of days.

This plan is for US DTC brands that already have products, customers, creative assets, and sales data but need a clear way to move into Amazon without losing control of margins, inventory, or brand consistency.

For general launch basics, use SalesDuo’s Amazon product launch checklist. This guide focuses specifically on what changes when an established Shopify brand starts selling on Amazon.

The 90-day decision snapshot

Use these 90 days as a planning framework. Amazon does not require you to complete specific steps by Day 30, Day 60, or Day 90.

Your real launch date may change due to product approvals, FBA receiving times, compliance checks, or inventory delays.

You should not force a launch date if any of these five problems still exist:

• You do not have a SKU-level contribution model that includes Amazon fees, fulfillment, returns, promotions, and advertising.
• You are still unsure about brand ownership, product compliance, or category eligibility.
• No one knows which system is the main source of truth for Shopify and Amazon inventory.
• Your creative is still built only for DTC shoppers and has not been adapted for Amazon.
• No one clearly owns Amazon catalog work, advertising, inventory, and issue escalation.

Why a Shopify bestseller may need a different Amazon launch plan

A product that sells well on Shopify has already proven that customers want it. But that does not automatically mean it will perform the same way on Amazon.

DTC growth often depends on your brand creating demand through paid social, email, your website, landing pages, and customer relationships.

Amazon works differently. Many shoppers arrive already knowing what product type they need. They quickly compare several competing products and look at price, delivery, product information, images, and reviews.

Because of this, the main question is not:

“Can this product sell?”

The better question is:

“Which product has the best chance of working on Amazon without hurting our margins, inventory, or brand position?”

Your Shopify sales history is useful, but it should not be the only reason you choose a product for Amazon.

Choose a hero SKU, not your entire Shopify catalog

Start with one strong SKU or a very small group of products.

Compare possible products based on:

• How well they match Amazon search demand
• Contribution margin
• Product or category restrictions
• Product size and weight
• How different they are from competing products
• Available inventory

Amazon’s Product Opportunity Explorer helps Professional sellers review search, purchase, review, return, and competition data. However, Amazon also makes it clear that this information is only a guide. It doesn't guarantee a product will succeed.

For a deeper product-screening process, use SalesDuo’s framework to validate demand before launching on Amazon.

Strong Shopify sales do not mean every variation is ready for Amazon.

Days 1–30: make the brand and operation Amazon-ready

The first 30 days should end with a decision on readiness.

Do not launch just because you reached Day 30.

If your seller registration, category approval, inventory, product identifiers, or compliance documents are not ready, move the launch date. Do not try to solve these problems by spending more money on advertising.

Align brand ownership, eligibility, and catalog identifiers

First, decide who owns the Seller Central account, user permissions, catalog updates, and issue escalation.

Check the exact product and category rules for the US marketplace before launching.

For branded products, review the current Amazon Brand Registry requirements and Amazon’s official enrollment rules before depending on Brand Registry features.

Remember that Brand Registry is different from category approval and seller account registration.

You also need to correctly map your Shopify SKUs and variations to Amazon.

Amazon commonly uses GTINs, such as UPCs, to identify products. Each product in Amazon’s catalog has an ASIN.

Decide:

• Which Shopify variations should become Amazon parent/child variations
• Whether any of your products already exist in Amazon’s catalog
• Who is allowed to update shared Amazon catalog information

Decide how Shopify and Amazon inventory will work together

Before your first Amazon order arrives, decide which system will be the main source of truth for available inventory.

Clearly define:

• SKU mapping
• Safety stock
• Who handles replenishment
• How you prevent overselling
• Fulfillment cutoffs
• Returns
• What happens when something goes wrong

A connector can reduce manual work, but it cannot fix unclear responsibilities.

Shopify Marketplace Connect can connect Amazon listings, orders, and inventory with Shopify. Sellers can also manage Amazon pricing, quantity buffers, and fulfillment settings.

But treat Marketplace Connect as a tool, not a complete solution.

Before launch, decide what your team will do if:

• Inventory does not sync correctly
• A sync is delayed
• Inventory becomes stranded
• You need to switch between FBA and FBM

Assign an operations owner to review sync errors and available stock before increasing Amazon demand. If inventory data becomes unreliable, that owner should investigate the mismatch, protect safety stock, and pause affected offers or advertising when needed. Resume only after the team confirms that available quantities and fulfillment settings are correct on both channels.

If you are still choosing your fulfillment method, compare FBA vs. FBM for new Amazon sellers based on your product size, delivery needs, operations, margins, and how much inventory you are comfortable sending into Amazon’s network.

Rebuild the first listing for Amazon shoppers

Do not simply copy your Shopify product page and paste it into Amazon.

Start with Amazon-specific keyword research. Then create your title, bullet points, images, and other content based on how Amazon shoppers search and compare products.

Make sure your product claims match the evidence you have and follow the rules for your category.

Your existing DTC creative can still be useful. You may already have strong product photos, product demonstrations, proof points, and brand assets.

However, you may need to change how you use these assets.

Amazon shoppers need to quickly understand:

• What makes the product different
• Which variation is right for them
• What important features the product has
• Why they should choose it over competing products

A simple Shopify-to-Amazon handoff can stop your team from assuming that every DTC asset can be copied directly.

Establish channel-level launch economics

Before setting your PPC budget, build a contribution model for each SKU.

Amazon selling fees vary by product category. You may also need to pay for fulfillment, storage, inbound shipping, returns, promotions, and advertising.

Use the actual category, product size, package weight, fulfillment method, and expected return rate for your SKU. Do not copy a general Amazon fee percentage and assume it applies to your product.

Compare Amazon and Shopify over the same time period.

For Amazon, your unit contribution can include:

Net selling price minus product cost, referral fee, fulfillment and handling, storage or inbound costs, returns, promotions, and Amazon advertising.

For DTC, your unit contribution can include:

Net selling price minus product cost, payment fees, pick and pack costs, shipping, returns, and DTC advertising.

The example below is for illustration only.

A $40 product may have very different profits on Amazon and Shopify even if the selling price is exactly the same.

The numbers below are invented placeholders. They are not current Amazon fee rates or SalesDuo benchmarks.

This example assumes one completed order at a $40 net selling price on each channel. All costs are hypothetical per-order allocations. The Amazon fulfillment and inbound line does not separately itemize storage costs, and the model excludes one-time setup expenses and fixed monthly overhead. Add those costs when building your own launch budget.

Returns can also change the comparison. If the expected Amazon return allowance rises from $2 to $4 per order, estimated Amazon unit contribution falls from $6 to $4, assuming every other cost stays the same.

Small changes can make a big difference.

In this example, if Amazon advertising costs increase by $3 per unit, Amazon contribution falls from $6 to $3.

A brand should move forward only when the expected contribution and available inventory fit its own level of acceptable risk.

There is no single ACoS number that makes every Amazon product launch profitable.

Days 31–60: launch one controlled Amazon cohort

Once your chosen ASINs are available for purchase, properly stocked, compliant, and measurable, launch a small controlled group.

On Day 31, your goal is not to reach as many people as possible.

Your goal is to collect clean data and understand whether Amazon shoppers understand the offer and whether your operations can handle the orders correctly.

Before going live, complete a simple operational check.

Make sure:

• The listing can be found and purchased
• The correct offer and price are active
• The team knows which inventory is available
• Amazon results are tracked separately from Shopify
• Someone can fix catalog problems
• Someone can pause advertising
• Someone owns inventory replenishment
• Someone has the final decision if the launch creates a serious margin or customer experience problem

These checks help you avoid blaming weak customer demand for an operations-caused problem.

Launch visibility, reviews, and operations responsibly

Before sending more traffic to the listing, make sure customers can actually buy the product.

Check that:

• The correct offer is live
• Inventory is available
• Orders are being recorded properly
• Returns are visible and accurate

If Featured Offer eligibility matters for your product, monitor it as part of your listing’s buyability.

Don't assume spending more on ads can fix an offer problem.

Use Sponsored Products as a controlled traffic source.

For detailed campaign setup, use the Amazon launch campaign and tool stack.

For this launch plan, focus on three questions:

• Are you getting relevant search terms?
• Are the right shoppers converting?
• Is the contribution trend acceptable while you are still learning?

For reviews, use only Amazon-approved methods.

Amazon Vine is only available to eligible sellers and products. Eligibility may depend on conditions related to FBA, existing review counts, and brand roles.

Never pay for positive reviews or offer rewards only when someone leaves a positive review.

If you use influencers, free samples, or other endorsements outside Amazon, follow FTC rules and clearly disclose important relationships when required.

Measure Amazon demand without confusing it with Shopify lift

Keep Amazon performance separate from your normal DTC performance.

On Amazon, track:

• Sessions
• Conversion
• Search terms
• Advertising spend
• Returns
• Stockouts
• Unit contribution by SKU

On Shopify, watch:

• Sales for the same SKU
• Paid advertising efficiency
• Direct traffic
• Branded demand

An increase in Amazon sales does not always mean every Amazon sale is new.

Some Amazon customers may have bought from your Shopify store if Amazon had not been available.

When your account is eligible, Amazon Attribution can help measure how off-Amazon channels such as search, social media, email, display ads, video, affiliates, and influencers affect Amazon shopping activity.

Amazon Attribution can show Amazon shopping activity associated with eligible off-Amazon campaigns. It does not, by itself, prove that every attributed purchase is incremental. Compare those results with Shopify's same-SKU sales, branded traffic, marketing costs, and contribution trends before deciding whether the new channel is adding profitable demand.

Use tagged traffic sources where possible.

This helps you avoid putting all external traffic into one general “Amazon lift” number.

Days 61–90: decide what to scale, fix, or pause

By the third stage, stop focusing only on activity.

The important question is not:

“How much money did we spend?”

It is also not:

“How many campaign changes did we make?”

The real question is:

“Has this SKU earned more inventory and advertising budget?”

Make this decision based on demand quality, contribution, stable operations, and brand control.

Set go / improve / pause criteria for each launch SKU

Use trends instead of one universal benchmark.

Different categories have different margins, prices, repeat-purchase behavior, advertising costs, and conversion rates.

Go / scale: Relevant search terms are producing better conversion, unit contribution is acceptable for your business, inventory is stable, and there are no unresolved catalog or compliance problems.

Improve: Customers are reaching the listing, but something such as the offer, images, price, search terms, or fulfillment setup is limiting conversion. Fix the problem before spending much more.

Pause: Contribution remains too weak, inventory risk is high, search terms show poor product-market fit, or catalog and policy problems make the test unreliable.

Compare Both Channels Before Scaling

These comparisons identify possible channel shifts. They do not establish incrementality without stronger measurement.

For a deeper look at how to divide traffic after Amazon is running, use SalesDuo’s Amazon vs. Shopify traffic strategy.

Keep that analysis separate from the initial launch plan.

Setting up a new channel and deciding where to send long-term traffic are two different decisions.

Build a 90-day review and ownership cadence

Make Amazon launch management a regular process across teams.

Run:

• A weekly review of merchandising, advertising, inventory, and catalog issues
• A finance review every two weeks to check contribution and forecast risks
• A monthly comparison of Amazon and DTC performance

Each time, record:

• The decision
• The owner
• The evidence used
• The next review date

This is important because many Amazon problems involve more than one team.

For example, a weak conversion rate may look like an advertising problem when the real issue is pricing, inventory, catalog setup, or listing content.

What should a DTC brand outsource for its Amazon launch?

Outsourcing can make sense when your internal team lacks enough Amazon experience or when managing work across teams becomes too difficult.

Keeping the work in-house can make sense when your team already has experienced owners and enough time to manage catalog, advertising, finance, and inventory decisions after launch.

Example: When a DTC Brand Should Delay Its Amazon Launch

Illustrative operating scenario, not a SalesDuo client case study.

A Shopify brand has a strong-selling product and wants to launch it on Amazon. Its product content is ready, but the operations team has not confirmed how Shopify and Amazon will share available stock.

The marketplace lead recommends delaying paid traffic. Operations first maps the SKUs, establishes a safety-stock buffer, and tests how orders and inventory updates move between systems. Finance then checks the Amazon contribution model using the selected fulfillment method.

The brand proceeds only after the team confirms that the listing is buyable, inventory ownership is clear, and the test budget fits its risk limits. The lesson is that a launch delay can be a sound operating decision when the alternative is unreliable inventory or unclear economics.

Do not choose an agency because it promises guaranteed ROI.

Choose based on the gaps in your own team.

Ask:

• Who owns each part of the launch?
• What data will the agency review?
• How are decisions recorded?
• When will the team pause a launch instead of continuing to spend money on a broken setup?

Your next step: launch an Amazon channel, not just an ASIN

A strong DTC-to-Amazon launch keeps product selection, inventory, catalog work, advertising, and finance connected from the first readiness check through the Day 90 review.

If your brand needs an experienced team to define these workstreams and identify launch problems before you start scaling, review SalesDuo’s Amazon product launch program.

We're not trying to force everything into a fixed 90-day schedule.

The goal is to build an Amazon channel that your team can measure, manage, and grow without losing focus on the DTC business that already works.

Frequently Asked Questions about Launching an Amazon Product

Can I sell products from my Shopify store on Amazon?

Yes. A Shopify brand can sell the same products on Amazon.

However, Amazon has its own catalog, offers, seller account, fulfillment settings, policies, and costs.

You can connect and map your Shopify products to Amazon, but you should not treat Amazon as a simple copy of your DTC store.

Should I launch every Shopify SKU on Amazon?

Usually, no.

Start with one strong SKU or a small group of products.

This makes it easier to test Amazon demand, margins, inventory flow, and catalog operations without risking your entire product catalog.

Add more products only after the first group gives you reliable data.

How long does it take to launch a Shopify brand on Amazon?

There is no guaranteed 90-day timeline.

The 90-day plan in this guide is a framework to prepare, launch carefully, and decide what to scale.

Seller registration, category approval, product compliance, inventory movement, and FBA receiving times can all affect the actual launch date.

Can Shopify and Amazon share inventory?

Yes, Shopify and Amazon can share inventory data through connectors and operating rules.

However, you still need one clear source of truth.

Decide whether inventory will stay in your own warehouse, FBA, or both.

Also set safety stock levels and decide what your team will do if inventory doesn't sync correctly or a sales channel starts running low.

Do I need Amazon Brand Registry to launch?

Not always.

A product does not necessarily need Brand Registry simply to be sold on Amazon.

However, Brand Registry gives eligible brands access to additional brand-building and protection tools.

Brand Registry eligibility is different from seller registration and category approval.

Always check the latest requirements before making it an important part of your launch plan.

Will Amazon sales cannibalize my Shopify sales?

They can.

Some Amazon orders may be completely new sales, while others may come from customers who would have purchased through your Shopify store.

Compare sales for the same SKU, customer acquisition sources, contribution, and branded demand across both channels before assuming all Amazon revenue is new revenue.

How should I budget Amazon PPC for a new DTC SKU?

Start with your SKU economics instead of using a general percentage of revenue.

Choose a test budget your contribution model can support.

Be clear about what you want to learn from search terms and conversion data.

Increase spending only when the listing, offer, and operations are giving you reliable signals.

Should a DTC brand hire an Amazon launch agency?

An agency can help when your team lacks enough Amazon experience in catalog management, advertising, fulfillment coordination, or analytics.

Compare what the agency will handle with the gaps in your own team.

Avoid agencies that promise fixed rankings, guaranteed review numbers, or guaranteed revenue by Day 90.
