A direct AdSense account is yours alone, self-managed. MCM (Multiple Customer Management) is a Google Ad Manager structure where a parent manages a child’s inventory or account under one of two modes: Manage Inventory or Manage Account.

A direct AdSense account is one you apply for and run yourself: you own the account, apply the ad code or Ad Placement API calls, and Google pays you directly. MCM (Multiple Customer Management) is a Google Ad Manager structure where a partner (the parent) manages inventory or an account on behalf of a publisher (the child). There are two modes, and they work very differently.
In Manage Inventory, the child delegates inventory to the parent. Both sides have Ad Manager networks, but no trafficking happens in the child’s network – sites are tagged with the parent’s Ad Manager tags, Google pays the parent, and the parent pays the child. In Manage Account, the parent gets access to the child’s own Ad Manager account; the child keeps its permissions and settings, Google pays the child directly, and the child can set the parent’s revenue share (0-100%) to be sent automatically. The child completes identity verification in this mode.
What does ads.txt need for MCM?
You add the ads.txt lines your MCM partner gives you to every site included in the program. Google does not publish fixed traffic thresholds for joining MCM; eligibility is handled by Google and the partner.
If you’d rather not manage Ad Manager setup, header bidding partners, and ads.txt entries yourself, Playgama Ad is a Google Ad Manager MCM partner and handles that setup, plus demand from other networks, through one SDK.
Next step: decide whether you want direct account control (apply for AdSense yourself) or delegate setup to an MCM partner and compare what each offers before you commit ads.txt entries to one.

Can I switch from Manage Inventory to Manage Account later?
The two modes are set up differently in Ad Manager; check with your MCM partner and Google’s documentation before assuming a switch is simple.
Do I need an AdSense account for MCM?
MCM operates through Google Ad Manager; requirements depend on the mode and your partner’s setup, so confirm directly with Google or the partner.
