Receiving merchant credit card payments

Would someone point me to the guide on how to correctly set up a merchant credit card account[s] in Manager? Several discussions on how to account for business expenses paid using a credit card, I need to know how to set up Manager to receive and account for invoices I issue and are paid by my customers, as well as the discount fees paid to the CC processor. There are references in other posts to a Manager credit card guide from 2018, but that link no longer working.

I would advise to always first go to Guides | Manager there in the search you can type for example credit card and that will give you the working link as provided Set up credit cards | Manager

The link that comes up is:

Set up credit cards

And it appears to be for making payments from a CC for business, not what I need.

“A credit card belonging to a business or used exclusively for business…”

let me see if I understand you correctly

You have customers - good
You invoice them
They pay you using a credit card service
The credit card service deduct a fee when they pass the payment onto to you

If this is correct, then one way to process this, assuming that you are not extending credit to your customers, that is, they pay for their purchases immediately

A customer purchases and pays for goods woth $100 and the credit card fee is $2.50

Create a Cash Sale for $100 with a line for the credit card fee of -$2.50

This will
credit your sales 100
debit your card merchant fee expense accout 2.50
debit your bank account 97.50

Did you mean:
credit your bank account 97.50 ?

No. A deposit to a bank account is a debit.

Oh, Ok. Learn something everyday.

Read the Guide about designing a chart of accounts. It includes a primer on debits and credits.
