SalesDuo brings Amazon strategy and execution under one plan. Our marketplace specialists and proprietary intelligence system coordinate advertising, content, catalog, operations, forecasting and expansion—so every part of your Amazon business works toward profitable growth.
Built for established brands that need more than isolated PPC, SEO or catalog support—and want one accountable team connecting the entire Amazon operation.
A full-service Amazon agency coordinates the specialists, systems and recurring work required to grow and protect a brand on Amazon. Instead of separating advertising, listings, operations and inventory into disconnected projects, one team sets the priorities, assigns owners, executes the agreed work and measures the effect on sales, profit and marketplace health.
If you mainly need recurring Seller Central or Vendor Central support, review our Amazon account management services. Full-service support is broader: it connects account operations with advertising, creative, analytics, inventory planning and growth strategy under one operating plan.
We translate growth goals into a marketplace plan covering assortment, pricing, promotions, advertising, launches and expansion. Decisions are reviewed against contribution margin, TACoS, inventory position and long-term category growth—not revenue alone.
Amazon agency pricing guideWe coordinate keyword research, listing copy, images, A+ Content, Brand Stores and conversion improvements so the content shoppers see matches the traffic the brand is buying and the products it wants to grow.
Listing optimizationSponsored Products, Sponsored Brands, Sponsored Display and DSP are planned alongside organic rank, conversion, inventory and margin. The goal is not simply to spend more efficiently; it is to use advertising to support profitable total-account growth.
Amazon advertisingOur team manages the agreed operational work that can block growth: catalog corrections, variations, suppressed listings, support cases, account-health risks and recurring Seller or Vendor Central issues. Growth plans are adjusted when operational constraints affect availability or conversion.
Amazon account operationsWe connect demand signals, advertising plans, seasonality and stock position to help brands reduce lost sales from stockouts and avoid tying up margin in excess inventory. Recommendations remain aligned with the brand’s final supply decisions and operational constraints.
Amazon BI and forecastingBrands operating through 3P, 1P or a hybrid model need different plans for pricing, profitability, catalog ownership, purchase orders, shortages, chargebacks and advertising. We coordinate the model around the brand’s commercial goals instead of treating Seller and Vendor Central as identical channels.
Shortages and chargebacksWe assess whether new Amazon marketplaces, Walmart and other commerce channels are commercially ready before launch. The plan covers assortment, content, operations, advertising and reporting so expansion does not create disconnected work or hidden operational risk.
Amazon marketplace expansion guideExplore published client case studies. Each engagement has different scope, starting conditions and outcomes.
Results from individual client engagements over the periods shown. Performance varies by category, budget, competition and operations. Past results do not guarantee future outcomes.
Full-service support is usually the right model when Amazon is an important revenue channel, but execution is split across employees, freelancers or agencies; advertising and inventory decisions are disconnected; catalog or account-health problems keep interrupting growth; the brand is entering new marketplaces; or the internal team needs specialist depth without recruiting every role separately.
A full-service engagement may be more than you need if the account only requires a one-time listing fix, a narrow advertising project, occasional support cases or basic setup for an unproven product. In those cases, a specialist project, audit or focused account-management scope may be the better starting point.
Start with the written scope, not the size of the service list. A credible proposal should show which workstreams the agency owns, which decisions stay with the brand, who will do the work, what gets reported, how fees are calculated and how the relationship can end. Use the six checks below to compare providers on the same terms.
Ask whether advertising, listings, creative, catalog operations, inventory planning, account health, brand protection, reporting and expansion are managed, shared, advisory only, excluded or available for an additional fee. “Full service” should be defined in writing.
If you sell through Seller Central, Vendor Central or both, ask for current experience with that model and the operational issues that matter to it. Seller and Vendor Central require different processes, economics and escalation paths.
Ask for examples with a similar category, catalog complexity, marketplace model and growth stage. Strong evidence states the starting problem, the work completed, the result, the measurement period and any important limitations.
Meet the person responsible for communication and understand which specialists support advertising, content, catalog, operations and analytics. Ask how priorities are assigned, how urgent issues are escalated and how many approvals remain with your team.
Agree on the baseline, KPIs, reporting cadence and data access before work starts. Reports should explain what changed, why it changed, what the team will do next and which decisions require the brand’s approval—not simply provide a monthly PDF.
The proposal should explain the fee model, setup or project charges, contract and notice periods, account permissions, data ownership, content ownership, exclusions and transition support. A reputable agency should use appropriate sub-user permissions rather than request the brand’s primary login.
• Which parts of our Amazon business will your team manage, share with us, advise on or exclude?
• Who will lead our account, and which specialists will support that person?
• Can you show a relevant case study with the starting point, work completed and measured result?
• Which metrics will we review, how often will we review them and what data can we access?
• How is the fee calculated, and which work costs extra?
• What approvals and responsibilities remain with our internal team?
• What happens to our data, advertising structure, content and documentation if the engagement ends?
• Guaranteed rankings, revenue or sales outcomes before the agency audits the account
• A vague “full-service” label with no line-by-line scope or exclusions
• Requests for the primary Seller Central login instead of appropriate user permissions
• Reporting that gives no access to the underlying data or actions taken
• Fees, renewal terms, notice periods or ownership rules that remain unclear before signing
A full-service transition should create control before it creates more activity. The first 90 days establish the baseline, remove urgent blockers, align workstreams and build a repeatable operating rhythm.
Confirm goals, permissions, catalog and marketplace scope. Review financial targets, advertising, listings, inventory, account health, open cases and reporting. Record the starting metrics and identify risks that could block growth.
Turn the audit into a ranked plan. Assign an owner, expected output and review date to each priority across advertising, content, catalog, operations, inventory and analytics. Agree on approvals and escalation rules with the brand’s internal owner.
Your account lead coordinates the roadmap and communication. Advertising specialists manage retail media. Content and catalog specialists improve shopper experience and resolve structural issues. Operations specialists monitor account health, cases and marketplace execution. Analytics and strategy support turn data into priorities. Your internal team retains final control over budgets, product facts, supply decisions and major commercial approvals.
SalesDuo’s marketplace specialists remain accountable for strategy, approvals and execution. Ethan, our proprietary intelligence system, helps the team monitor performance, surface risks, connect signals across workstreams and prioritize the next actions. The result is faster visibility and more consistent follow-through—not unsupervised control of your Amazon business.

Your reporting can bring together SKU-level sales, advertising efficiency, organic visibility, conversion, inventory health, Buy Box risk, forecast gaps and expansion opportunities. Each review should end with named priorities, owners and next actions—not a dashboard without decisions.
Each review should end with named priorities, owners and next actions—not a dashboard without decisions.
A full-service engagement is scoped around catalog size, marketplaces, Seller or Vendor Central coverage, advertising complexity, creative needs, account condition, reporting requirements and the amount of execution the brand wants to outsource. Your proposal should state the recurring scope, assigned team, meeting cadence, approvals, exclusions and any project-based work separately.

Still have questions?
A full-service Amazon agency coordinates strategy and execution across advertising, listings, creative, catalog, account health, inventory planning, analytics and marketplace growth. The written scope should make clear what the agency manages, what is shared with the brand and which decisions remain with the brand.
Compare providers on six points: a written line-by-line scope, relevant Seller or Vendor Central experience, results from comparable brands, the assigned team, reporting and data access, and clear fees, terms and ownership rules. Ask to meet the account lead and confirm what your internal team will still own.
Account management usually focuses on recurring Seller Central or Vendor Central execution, such as catalog updates, cases, account health and reporting. Full-service support adds connected ownership across growth strategy, advertising, creative, inventory intelligence, analytics and expansion. The right model depends on how many functions the brand wants one partner to coordinate.
A specialist is usually the better fit when your internal team can coordinate the Amazon business and needs help with one defined function, such as PPC or creative. Full-service support fits brands that want one partner to coordinate several connected workstreams. Neither model is universally better; the right choice depends on scope, internal capacity and commercial goals.
The brand should retain an internal decision-maker, accurate product and financial information, supply and purchase decisions, legal and compliance approvals, final budgets and timely creative or commercial approvals. The agency can coordinate and execute the agreed Amazon work, but it does not replace the brand’s responsibility for product truth and core business decisions.
Use appropriate user permissions for Seller Central, Vendor Central, advertising and any agreed reporting systems. Grant only the access required for the contracted work, keep the brand’s primary credentials private and review permissions when roles or providers change.
FBA stores, picks, packs and ships eligible orders, but it does not manage advertising, listing quality, catalog structure, pricing strategy, account health, restock planning or marketplace growth. A full-service agency manages the agreed commercial and operational work around fulfillment.
Yes. SalesDuo supports Seller Central, Vendor Central and hybrid marketplace models. The exact scope should reflect the brand’s channel structure, including relevant catalog, advertising, operational, forecasting, shortage and chargeback requirements.
Use a documented baseline and a balanced scorecard. Depending on the engagement, measures may include contribution profit, total sales, TACoS, conversion rate, organic visibility, in-stock rate, Buy Box share, listing quality, unresolved account-health issues, launch progress and the internal hours replaced. Agree on attribution limits before judging results.
The timeline depends on the account’s starting point, inventory, category, approval speed and the work required. Some controllable fixes can be completed early, while catalog cases, organic rank, new launches and operational changes may take longer. The first 90 days should establish the baseline, fix urgent issues and create a measurable growth plan rather than promise a universal result.
If advertising, content, catalog, operations and inventory are being managed separately, the gaps between them can limit growth. Book a 1:1 growth call to review your current setup, identify the highest-priority ownership gaps and decide whether a full-service model fits your brand.
Hear it straight from our successful clients. Discover what SalesDuo's partners have to share about their experience.
SalesDuo has the experience and history with Amazon that encouraged us to work with them. This has helped us devote more time to our day-to-day operations and less time to navigating Amazon. We have more than tripled our sales on Amazon since working with SalesDuo. We have also made goals to triple it again this year.
We used a different consulting firm to manage our Amazon business. Sales grew but my team and I decided we needed to make a change. We happened to bump into SalesDuo. Since then our sales have increased dramatically. We look forward to our weekly calls and they have great knowledge of how Amazon works. I highly recommend them.
In 2020, even though our sales were growing we were struggling to get the expertise we needed to manage our Amazon business which can be challenging. We are impressed with the knowledge that the SalesDuo team brings to the table, the attention we get when issues arise and resolving them quickly as well as the professionalism they bring as a company.
SalesDuo has done a superb job and proved to be truly one of the best partnerships in 15 years. They have delivered when others talk. We are experiencing 134% growth year over year with Amazon and climbing. They helped us navigate Walmart Marketplace. They are successfully managing our AMS advertising budget. Our Account Manager is extremely professional and responsive to all requests. I often wonder if he sleeps.
Partnering with SalesDuo has given a greater insight into our overall Amazon business through analytics, AMS spend efficiencies, as well as correcting specific ASIN needs. The SalesDuo team is always responsive and interactive and has helped to promote our overall Amazon growth with their experiences and expertise. Having a weekly meeting to review our current plans is important to our continued understanding of both our Vendor and Seller Central.
SalesDuo has helped me execute my backlog of ideas quickly and effectively, always tweaking to improve where needed.
We initially reached out to SalesDuo because we needed help fixing our listings on Amazon. Other sellers began to upload wrong/poor-quality photos and grouped or separated products incorrectly. In addition, copycat companies began selling very poor-quality products similar to ours on Amazon by using our keywords and stealing our customers. We noticed that these issues resulted in declining Amazon sales.
Once contacting SalesDuo I was pleasantly surprised at the scope of work they covered and the competence of the company. We started with managing our Seller Central and Vendor Central accounts, quickly realizing they could handle all the advertising too. From forecasting to reporting and everything in between SalesDuo has exceeded our expectations. Not to mention the value is unmatched by any other company.
We needed an Agency that could bring behind-the-scenes Amazon experience to take the load off our internal team. SalesDuo had insider Amazon experience, plus a full team to support us. Our current SalesDuo rep truly seems to care about our success. And whenever we have problems, he patiently pursues them, and if needed, researches the answers so that we truly have an agent acting on our behalf.
In Jan 2018 we had a brand transition and were experiencing a list of problems when we reached out to SalesDuo. We lost our sales volumes - what was once a truckload got to individual bag orders. We had catalog issues. No one at Amazon could or would help us. SalesDuo has been able to restore our sales on Amazon by prompt resolution of a multitude of issues.
Having a team of subject matter experts available to work with us is very beneficial to our company and our sales. SalesDuo has helped us grow our brands on Amazon by adding variations, images, copy, A+ pages, ads and even assisting with customer support. SalesDuo has allowed us to focus more on non-Amazon-related tasks while they handle what would take us days prior.
About 5-6 years ago Amazon approached us and asked to carry our products via Vendor Central. Finding SalesDuo has been game-changing for our business. Their patience, ability to control me from journeys down rabbit holes, and knowledge of Amazon's pitfalls and secrets have truly allowed to get a solid mid-six-figure business on Amazon and with SalesDuo’s help, it has continued to grow. Our sales went up 200% over last year!
I would give SalesDuo 6 Stars out of 5 if it was possible. As a group, the knowledge and insights SalesDuo provides have been invaluable in our growth strategy. SalesDuo is managing the SEO and ACOS just as we discussed, and our promotions and coupons have remained profitable. The assistance does not end there - they have provided guidance in the annual vendor negotiations and benchmarks against which to measure our success.
SalesDuo is a full-service Amazon and eCommerce agency. We use our proprietary AI system and an expert eCommerce team to grow sales and profits for brands globally.
