Business expenses in a cash flow projection: what belongs outside accounts payab

A cash projection only works if every expected outflow appears exactly once. The easiest way to break it is to confuse two categories: bills you track as accounts payable, and payments that never touch the payables ledger at all. This page is about the second group, the ones bookkeepers usually label business expenses in a projection worksheet.

What counts as a business expense in a projection?

In projection terms, a business expense is any cash payment you expect to make that is not tracked as a bill in accounts payable. The usual suspects are loan and note repayments, payroll runs, owner drawings, HP or finance-lease instalments, and recurring payments set up as memorized or recurring transactions rather than entered as supplier bills.

These payments are real cash out but they never appear in your payables ageing. If your projection draws only on open bills, it will quietly overstate available cash. That is the failure mode we see most often: a projection that looks healthy right up to the week a payroll run and a loan instalment land together.

How do you keep it from double-counting?

The rule is simple: each expected payment appears in one place only. If an outflow is already an open bill, it comes through the payables side of the projection. Do not re-enter it as a business expense. If it is a memorized transaction that will post as a bill, treat it as payables. If it posts straight to the bank or credit card, treat it as a business expense.

Payroll deserves a note. Gross wages, employer taxes and any deductions all leave the bank in one net payment, sometimes with a separate remittance to the tax authority a few days later. Split them into the payments you will actually make, on the dates you will actually make them, rather than one lump on payday.

How much detail is enough?

A projection is a summary of cash activity, not a second ledger. Include the significant, recurring outflows: debt service, payroll, rent paid by standing order, insurance by direct debit. Immaterial items add noise and invite stale entries. Review the list each time you refresh the projection, because a saved list of expenses keeps its figures until you change them. A loan you refinanced last quarter will still be projected at its old amount if nobody updates it.

Where does this sit in the close?

The projection itself is not part of the month-end close, but its inputs are. If memorized loan payments posted late, or payroll accruals were cut off wrongly, the projection inherits the error. Reconcile the bank first, confirm the payables list is complete, then layer the non-bill expenses on top. That sequence gives you a projection you can actually defend to an owner or a lender.
