Question

How you keep your meta ad backend clean and productive.

Having actual problem with Meta business Manager, Business Portfolio, ad manager and related CAPIs.

Please let me know, if I am right or wrong :

I have business portfolio(aka known as Business Manager, right?), where we can get access to multiple ad accounts from our clients in a single portfolio, right?     OR

we get our clients to create their business manager (including ad account) and then ad it into our portfolio to run ads on their behalf?     OR

Other way around?

You're asking all the right questions — Meta’s backend setup is notoriously confusing. Let’s clear it up step by step and keep it straightforward.

First — Terminology:

• Business Manager (now called Business Portfolio) = Your main dashboard where you manage assets (ad accounts, pages, pixels, domains, catalogs, etc.) across multiple businesses.

• You can own assets or just have access to assets shared with you.

Now, your main question: "Do I create one Business Manager and add client ad accounts into it? Or do clients create their own Business Managers and share with me?"

The correct and clean setup is: 

Each client should have their own Business Manager, and they should:

• Create their own ad account, pixel, domain verification, CAPI, and page

• Then assign access to your Business Manager (agency BM)

This way:

• They own their assets (very important for long-term integrity)

• You stay clean and compliant on your end

• Meta likes this structure — it reduces confusion, data ownership issues, and attribution problems

How to keep your Meta ad backend clean:

1. Use one main Business Manager for your agency (your "portfolio")

2. Ask each client to create their own Business Manager (if they haven’t already)

3. Ask them to share their assets with you, including:

   • Page

   • Ad account

   • Pixel

   • Conversions API (if set up via Events Manager)

4. Use Partner Access — not individual employee access — to request what you need

5. Inside your BM:

   • Keep each client organized in their own folder

   • Label assets clearly (e.g., “SmithCo – Pixel” instead of “Pixel 1”)

   • Use custom naming conventions to reduce errors

   • Audit permissions monthly to make sure people have the right roles

Common Mistake (sounds like your current setup):

“I add the client’s ad account directly into my Business Manager and manage it like it’s mine.”

That works short-term, but it creates:

• Ownership issues (client can’t control their own assets later)

• Tracking confusion (pixels and events tied to wrong BM)

• Complicated setups with CAPI (you may not have proper access to their server or domain)

Cleanest flow for CAPI:

• Client sets up domain + pixel + CAPI from their BM

• You help configure it via Events Manager if needed

• They assign you access to manage these assets
