P

Partial payment

A payment that settles only part of an outstanding invoice, leaving a remaining balance still owed by the customer or still due to a supplier. In Xero, partial payments require deliberate allocation so both the cash receipt and the residual debt are recorded correctly.

Payment allocation

The act of linking a cash receipt or payment to the specific invoice or invoices it settles, so that both the bank transaction and the outstanding balance are cleared correctly in the accounts. Unallocated payments leave invoices falsely open and distort aged debtors or creditors.

Payout decomposition

Payout decomposition is the process of breaking a single net payout from a payment processor — such as Stripe or Shopify Payments — into its constituent parts: gross receipts, processing fees, refunds, and any other deductions, so that each component can be posted to the correct nominal account in Xero.

Prepayment

A prepayment is an amount paid in advance for a good or service that has not yet been delivered, recognised as an asset on the balance sheet until the underlying benefit is consumed and the cost is released to the profit and loss account.

Processing fees

Processing fees are the charges levied by a payment processor — such as Stripe or PayPal — for handling card transactions, deducted from gross receipts before funds are settled to your bank account and requiring separate recording in Xero as an expense rather than a reduction of income.

Profit and loss

A financial report that shows your business's income, direct costs, and operating expenses over a set period, resulting in a net profit or net loss figure. It answers the question of whether the business made or lost money in that period.
