Accounts payable is the part of a company that writes checks out. Accounts receivable is the part of a company that brings the money in.
We’re super-small (family company, I do the business side and I really keep it simple – not much fancier than having a checkbook).
Anyway, what I mean is: there’s no way to know if/when we’ll get future customers. Lots of hope involved because the business we do (animal removal) is one-time-only for each customer usually, so we depend greatly on word-of-mouth and stuff, along with normal advertising crud.
