What details should an invoice include?
Name the provider and client, describe each line item, show quantity and price where relevant, and state the issue date, due date and amount owed. Those details let a customer check the bill before paying. The example numbers invoices and calculates exact totals; decide how tax, discounts and late terms should appear for the business’s real situation.
How does a private payment link help a client?
It gives the client a direct route from the invoice to the amount due, without requiring them to find a separate payment page. Confirm that the link identifies the right invoice and that the client can tell whether payment succeeded. The sample uses pay-by-link billing; include the invoice number in the confirmation so both sides can match the payment to their records.
What should happen if a paid invoice needs correcting?
Keep the original payment history understandable and record the correction as a new adjustment, credit or replacement document according to the business’s process. Do not silently rewrite a record that a client already paid. The example treats paid invoices as immutable; explain the correction to the client and make the updated balance easy to verify.
