Invoice vs. Statement of Account
Invoices and statements look similar but do different jobs: an invoice demands payment for specific work, while a statement summarizes everything a client owes. Using both correctly makes collections smoother. Here is the distinction.
What Each Document Does
An invoice is issued per transaction — it describes specific goods or services, states the amount due, and sets the payment deadline. It is the document that creates the obligation to pay. A statement of account, by contrast, is a periodic summary listing all open invoices, their dates and amounts, payments received, and the total balance outstanding.
Think of it this way: invoices are the individual charges; the statement is the running tab. A client with five open invoices receives five invoices but one statement showing all five at a glance.
When to Send Statements
Send statements monthly to clients with ongoing billing — typically at month end, covering all unpaid invoices. They are especially valuable when several invoices are overdue: one statement showing the full aging balance is harder to ignore than scattered individual reminders.
Statements also catch errors: clients often spot a missing credit note or a double-billed invoice on a statement that they missed on individual invoices. That reconciliation value is why accountants love them.
Using Statements for Collections
A statement with an aging breakdown (current, 30, 60, 90+ days overdue) is one of the most effective collection tools — it confronts the client with the total picture, not just the latest invoice. Pair it with a cover note: 'Attached is your statement showing $X outstanding across N invoices; please arrange payment or contact me to discuss.'
For seriously overdue accounts, the statement becomes your evidence pack: it documents every invoice, every payment, and the running balance. If a dispute escalates, this paper trail is what you (or a collections agency) work from.
Statements Are Not Invoices
Do not use a statement as a substitute for invoices — tax authorities generally require proper invoices with sequential numbering for VAT/GST and deduction purposes. A statement summarizes; it does not create the tax point or replace the invoice in your numbering sequence.
Similarly, do not re-send old invoices as if they were new when chasing payment — resending can confuse numbering and dating. Send the statement, and re-attach copies of the original invoices marked 'copy' if the client needs them.
Frequently asked questions
Should I send a statement if only one invoice is outstanding?
It is usually unnecessary — a reminder referencing that single invoice is clearer. Statements earn their keep when a client has multiple open invoices or you bill them regularly.
How often should I send statements?
Monthly is standard for ongoing client relationships. For one-off clients with a single overdue invoice, stick to the reminder sequence instead.
Can a statement replace an invoice for tax purposes?
No. Tax invoices must meet specific requirements (sequential numbering, tax breakdowns, registration numbers) that statements do not. Always issue proper invoices, and use statements only as summaries.
