Cash movement follows receipts and payments
Payments collected describe money received during the month. They may relate to invoices from this month or an earlier one. Looking at receipts beside costs can help describe part of a period’s cash movement, but those two totals alone are not a full cash-flow statement or a measure of the cash in a business account.
Profit uses accounting treatment
Accounting profit depends on how revenue and expenses are recognized and on the costs and adjustments included in the books. Payments collected less the costs entered in a Snapshot is only that subtraction. It leaves out anything not listed and does not apply accounting adjustments, so it should not be read as profit.
Read invoiced and collected totals side by side
Invoiced revenue records the amount invoiced during the selected month. Payments collected records receipts entered for that month. The Snapshot compares those monthly totals; it does not match a payment to an invoice or determine which invoices remain unpaid.
For context, use the same reporting month and definitions as your own records. Pencairn presents the arithmetic you provide and does not verify the underlying records or explain why amounts differ.
