Payments

I have made two screenshots.

On the left is the Bill that Company B will enter, and the Negative I put here could be on a Vendor Credit; it represents the Debt balance = the Liability to be paid later.

On the right is the Credit Card Charge that Company A will enter, because Company A paid for this on their AMEX, but it is to be Repaid to Company A by Company B.

So, later, Company A pays out the debt (liability) on the Check on the Expenses tab and Company B Processes a Deposit entry "from" their Other Asset.

No, I never stated anything about Pretend accounts.

I hope this helps.
