How to Manage Several Client Stores With Separate Profiles Without Mixing Them Up (2026)

Why do client stores get mixed up? #

Most mix-ups come from the same four shortcuts as with ad accounts:

1. One shared login for the whole team, so nobody knows who changed what.
2. One browser for every store, so cookies, saved passwords and open tabs sit side by side.
3. Files reused across clients, such as a product spreadsheet or a report template.
4. Names that don't say whose it is, so the wrong store gets edited.

For the advertising version of the same problem, see how agencies manage client ad accounts without mixing data.

What is the safest ownership model? #

The client owns the store, the seller account and the payout details. Your agency gets staff access with only the permissions each person needs. Shopify's help centre describes staff accounts as a way to give your team access to the store, with roles and permissions that control what each person can do. Other marketplaces offer similar sub-accounts or user permissions: check each platform's help centre.

Two cautions:

• Don't share one owner login across your team. Give each person their own.
• Follow each platform's rules on how many accounts a business may hold, and don't open extra accounts to get around them.

How should you set up the work? #

A browser profile keeps one store's cookies, logins and extensions in one place; see what a browser profile is.

Onboarding checklist #

1. Confirm who owns the store and the payout details. It should be the client.
2. Ask the client to give your team staff access, and agree the permissions in writing.
3. Make sure each person has their own login with two-step verification.
4. Create a browser profile for the store, set its address and region, and sign in only with personal logins.
5. Create the client's folder and apply the naming convention.
6. Record who has access to what, and when it was granted.

Offboarding checklist #

1. Remove team members' access as soon as they leave the project.
2. Remove your agency's access when the contract ends, or ask the client to.
3. Return or transfer any ownership you hold.
4. Delete data you no longer need: profiles, exports and shared files.
5. Hand over files and confirm the handover in writing.

A ten-minute monthly check #

• List everyone with access to each store and remove anyone who doesn't need it.
• Confirm two-step verification is on for every person.
• Check names against the convention.
• Review the profile list: one per store, none left over from past clients.

Common mistakes #

1. Sharing the owner's password because it's quicker.
2. Owning a client's store inside your own agency account, which makes handover hard.
3. Using one profile for several clients.
4. Mixing payout or banking details between clients.
5. Skipping offboarding, so old access lingers.

Where ADSSPEED fits #

Each ADSSPEED profile has its own cookies, storage and proxy, so a store's session stays apart from every other store's, and you can open, stop and assign proxies to many profiles at once. Use it only for stores you own or are authorised to manage, and follow each platform's rules.
