You enter an invoice for ten thousand. Which revenue account? Which receivable account? Nobody typed one. Where did they come from?
For each account type — revenue, receivable, freight, tax, unbilled, unearned — you configure where each segment of the account combination is sourced from: the transaction type, the salesperson, the customer site, a standard line item, or a constant.
This is the part that confuses people. AutoAccounting builds the combination piece by piece, and different segments can come from different sources. One three-segment account can be assembled from three different places.
Use the simplest sourcing that meets the requirement. A constant where the value never varies. Transaction type is the most common and most maintainable source for the natural account.
Then the walkthrough: configure AutoAccounting for revenue and receivable, enter a transaction, open the distributions and trace each segment back to its source, then deliberately change one source and re-enter to watch the account change.
This is the number one cause of "why is my revenue in the wrong account", and the number one thing new Receivables consultants cannot explain. And changing AutoAccounting after transactions exist does not retrospectively fix anything — existing distributions stay as they were.
