Agency-run stores create a predictable document problem. The brand owns the products and legal entity records, the agency controls daily listing work, and both sides assume the other can produce the file when a marketplace, customs officer or customer asks. That assumption holds until an account suspension, agency change or product complaint exposes a missing handoff.
Document custody is not about making the agency responsible for every record. It is about deciding who owns each source, who may edit it, where the current version sits and how the brand gets it back. A clear custody rule protects both sides because it reduces the chance that a commercial relationship becomes a scramble for account access and evidence.
Separate ownership from access
The legal seller should retain control of the core account identity: registration documents, tax details, payout information, primary login recovery and the authority to change account ownership. An agency may need operational access, but it should not be the only party capable of retrieving those records. Store the current documents in a location the legal seller controls and give the agency the access needed for its role.
Apply the same distinction to listings. The agency can prepare copy, images and campaigns, while the product owner keeps the documents that support safety, performance and origin claims. The listing file should link to the product evidence rather than allowing an editable campaign folder to become the only source of truth.
| File group | Custody owner | Agency access |
|---|---|---|
| Legal entity and tax records | Seller or brand finance lead | View only when needed |
| Account recovery and administrator access | Seller account owner | Named operational users |
| Product compliance evidence | Product or compliance owner | Reference for listing work |
| Listing assets and campaign records | Shared with version control | Create and edit within scope |
Write the handoff before the relationship changes
Put the handoff rules in the agency agreement or operating schedule. Name the accounts, marketplaces, administrator roles, document folders, return date for files and the process for removing access. Include a short requirement for the agency to save final listing versions, campaign approvals and platform notices in the shared record. These are ordinary working materials, not an extra compliance burden.
Test the handoff during the relationship. Once a quarter, ask the brand-side owner to retrieve the current account records, one product file and the latest platform notice without asking the agency where they are. If that takes days, the custody arrangement is too dependent on one person or one vendor system.
When an agency changes, preserve the account history before removing access. Download the final listing export where the platform allows it, save open case records and take dated screenshots of account settings. Then change passwords, administrator roles and recovery contacts under the seller's control. Avoid leaving the former agency as the only recovery route because an urgent account problem rarely waits for a contract dispute to end.
Use a live SKU to test the file
Choose one current SKU and trace it through the arrangement. The review should find the listing copy, product images, approval note, supporting product record, supplier or brand authorization and account owner. A missing link shows exactly which team needs to update the handoff.
Keep a short change log. Record when an agency gains or loses access, when a product file is revised and when a listing changes a material claim. This gives the brand a usable audit trail without forcing staff to preserve every chat message. The goal is a record that lets the legal seller answer a marketplace question even when the agency is unavailable.
Close the exit with a documented transfer
At the end of an agency relationship, make a dated transfer list. It should identify account administrators, recovery contacts, listing exports, open platform cases, active campaigns and the locations of product evidence. The seller-side owner should confirm access before the agency credentials are removed. A final email saying that documents were handed over is weaker than a list that the brand can test.
Keep that transfer list with the agency agreement. It gives the next team a starting point when a marketplace question refers to work completed by the former operator.
Review access records after a platform changes its permission model. A role that once allowed listing work may gain access to payout, tax or recovery settings after an update. The seller account owner should check those settings and revise the custody list before an emergency reveals that operational access has become control of the account. Keep a dated export or screenshot of the administrator list. It shows who could act for the account when a listing, payment or recovery decision was made.
Keep the access review with the transfer record. It shows that the seller, not the departing agency, retained control of the core account and evidence files.
Working file check. In the context of Document custody rules for agency-run marketplace stores, A practical test is to ask whether another colleague could repeat the decision from the file alone. If the answer depends on memory, a chat thread or an unavailable employee, the record is incomplete. Capture the product identifier, the relevant market, the evidence received and the point at which the decision must be reopened.
