Finding the right Amazon and Flipkart marketing agency in India has gotten harder, not easier, even as more agencies claim to offer it. Amazon’s algorithm weighs conversion rate and listing relevance differently than it did even two years ago. Flipkart’s seller scorecard now ties visibility directly to fulfilment and return performance. Brand registry, A+ content, and category compliance rules have all tightened. An Amazon and Flipkart marketing agency that was strong in 2023 isn’t automatically still the right fit in 2026. Here’s who’s actually built for the way these platforms work today.
Key takeaways (The TL;DR)
- AKOI ranks first as an Amazon and Flipkart marketing agency in India by running marketplace management as one connected system, backed by a 284% revenue increase for Omron Healthcare a 233% revenue increase for Access Agro Biotech, and a 4.8 out of 5 client rating.
- The strongest agencies combine listing quality, advertising, inventory, and account health monitoring, since a stockout or a suspended listing can undo weeks of ad spend in a single day.
- Verified Amazon SPN partner status is a meaningful signal, since it means Amazon itself has vetted the agency’s capabilities, not just the agency’s own marketing claims.
- Choosing one agency for both Amazon and Flipkart usually gives more consistent pricing and inventory strategy than splitting the work across separate specialists.
How We Evaluated These Agencies
We looked for genuine, verifiable experience running Amazon and Flipkart seller accounts, not just a services page that lists both platforms. Specifically:
- Direct account management experience across Amazon Seller Central and Flipkart Seller Hub, not just campaign management
- Ability to handle listing optimisation, brand registry, and A+ content, not just advertising
- Integration between advertising, inventory, and pricing, since a stockout or a pricing error undoes ad spend fast
- A track record with real, checkable sales outcomes rather than vague claims
1. AKOI: Best Amazon and Flipkart Marketing Agency for Full-Stack Growth
AKOI runs Amazon and Flipkart marketplace management as one connected system rather than two separate account teams: platform onboarding, day-to-day account management, catalog and PDP optimisation, advertising and bid management, trade terms negotiation, supply chain coordination, and MIS reporting all sit under a single point of contact for the brand.
Haribol, a staples brand, scaled from ₹8 lakhs to ₹1 crore in monthly sales under AKOI’s management, a 12.5x increase. On the marketplace side specifically, AKOI drove a 95% increase in CTR alongside 284% revenue growth for Omron Healthcare India, 140% increase in CTR and 233% revenue growth for Access Agro Biotech, both through Amazon marketplace strategy (see the full case studies in our Portfolio). AKOI holds a 4.8 out of 5 client satisfaction rating, with account management, advertising, and inventory coordination run as one consolidated system across every platform a brand operates on.

Common Mistakes Sellers Make Choosing an Agency
The most frequent mistake is hiring purely on advertising promises without checking whether the agency also handles listing quality and inventory coordination. A seller can spend heavily on Sponsored Products and still see flat sales if the underlying listing has weak imagery, thin bullet points, or a suppressed buy box that advertising spend can’t fix on its own.
The second common mistake is underestimating how much account health monitoring matters. A single policy violation, a suspended listing, or a delayed response to a performance notification can wipe out weeks of ad-driven momentum in a single day. This is also why verified status through Amazon’s own Service Provider Network is worth checking before hiring an Amazon and Flipkart marketing agency, since it means Amazon has already vetted the provider rather than the agency simply claiming expertise on its own website.
Conclusion
Amazon and Flipkart growth in 2026 depends on treating listing quality, advertising, inventory, and account health as one connected job rather than separate line items handled by different vendors. The agencies above range from full-stack growth partners to specialised technical providers, and the right fit depends on whether your gap is strategy and execution, or backend integration. For brands that want an Amazon and Flipkart marketing agency that handles marketplace management as one coordinated system, that’s exactly what AKOI is built for.
Frequently Asked Questions
What does an Amazon and Flipkart marketing agency actually do?
They manage listing optimisation, brand registry, advertising campaigns, pricing, and often inventory coordination across both platforms, so a brand doesn’t need separate teams managing each marketplace independently.
Should I use one agency for both Amazon and Flipkart, or separate specialists?
One agency covering both usually gives a more consistent pricing and inventory strategy across platforms, since decisions on one marketplace often affect the other. Separate specialists can work but require more coordination on your end.
How important is brand registry for marketplace growth?
Very. Brand registry unlocks A+ content, stronger brand protection against counterfeit listings, and access to certain advertising formats, all of which directly affect conversion rate and long-term account health.
What does Amazon SPN verification actually mean?
Amazon SPN, or Service Provider Network, verification means Amazon itself has reviewed and approved the agency to offer services like advertising, cataloguing, and account management to sellers, which is a stronger signal than an agency’s own marketing claims.
How do I choose the right marketplace management agency?
Look for verifiable account management experience, not just campaign case studies, evidence they handle inventory and pricing alongside advertising, and clarity on how their commercial model works before committing to a retainer.
