Amazon Retires the Solution Provider Invite Process: Why Every Seller Working With an Agency Needs to Reauthorize by September 3

On August 10, 2026, Amazon retired the invite-based system that agencies, freelancers, and software tools have used for years to get access to a seller's Seller Central account. Every service provider listed on the Solution Provider Network had to move to a new authorization flow through the Solution Provider Portal, and every seller who works with one now has a hard deadline: verify and update role coverage by September 3, 2026, or that provider's access simply expires. There is no grace period built into the announcement. Access that isn't reauthorized by the deadline stops working.

What Actually Changed

The old process was a manual handshake. A seller sent an invite from Seller Central, the agency or tool accepted it, and access stayed live indefinitely unless someone actively revoked it. Nobody tracked which roles were granted against which were actually needed, and access that should have been cleaned up years ago routinely wasn't.

The new process runs through the Solution Provider Portal and has three parts: the provider verifies its administrator's identity, submits business and contact information, and gets qualified for the specific data access roles it's requesting, inventory management, advertising, financial data, and so on. Once a provider is approved on a role, sellers can grant it two ways: an "Authorise Now" button directly on the provider's Solution Provider Network listing, or a direct authorization initiated by the provider itself. Both routes replace the old invite email entirely.

The Part That Catches People Off Guard

Reauthorization is not a rubber stamp on whatever access existed before. When a seller reauthorizes a provider under the new system, only the roles that provider is currently approved for on the Solution Provider Portal carry over. If an agency has been quietly using a role it was never formally approved for, and plenty have, that access does not survive the switch. It just disappears on September 3, with no warning beyond what's already been posted to Seller Central.

Why the September 3 Deadline Is Tighter Than It Looks

Three weeks between the process going live and the deadline is not much room, especially because the responsibility is split across two parties who don't always talk to each other proactively. The provider has to be approved for the right roles on the Solution Provider Portal first. Only then can the seller grant them. If a provider is still waiting on role approval when September 3 arrives, the seller's reauthorization has nothing to attach to, regardless of how promptly the seller acts on their end.

For sellers who work with more than one outside provider, agencies, PPC tools, repricers, accounting integrations, this deadline applies separately to each one. A seller running four connected tools has four authorizations to check, not one.

Who Should Be Paying Attention Right Now

• Sellers who have never personally logged into Seller Central to review which outside parties have standing access to their account. This deadline forces that review whether you were planning on it or not.
• Any seller working with a smaller or newer agency that may not have completed its Solution Provider Portal registration and role approval yet. Ask directly, don't assume.
• Sellers using automated tools, repricers, review management software, inventory forecasting, that connect through a service provider integration rather than the direct Selling Partner API. These count under the same authorization rules.
• Multi-account sellers or aggregators managing several Seller Central accounts through the same set of agencies and tools. Each seller-provider pairing needs its own reauthorization, so the count multiplies fast.

What to Do Before September 3

• Ask every agency, freelancer, and software tool with access to your account to confirm, in writing, that they've completed Solution Provider Portal registration and role approval. Don't take silence as a yes.
• Once a provider confirms approval, complete the reauthorization from your Seller Central account yourself. Don't assume it happens automatically just because the provider is approved on their end.
• Check the specific roles being requested against what that provider actually needs. This is a natural point to trim access that's broader than necessary, not just renew it as-is.
• If a provider you rely on can't confirm approval status by late August, ask what their plan is for September 3. A provider that hasn't started this process with three weeks left is a real operational risk, not a formality.

How TKL Helps

As a service provider ourselves, we completed our Solution Provider Portal registration and role approval as soon as the new process opened, and we've already sent reauthorization requests to every client account we manage so nothing on our side is waiting on Amazon's approval queue this close to the deadline. If you work with us, there's nothing you need to chase down.

For sellers who aren't clients but want a second set of eyes, we're happy to walk through your current list of connected providers and flag which ones look at risk of losing access on September 3. It's a fifteen-minute conversation now versus a scramble to restore ad management or repricing access after the fact.
