How to make a statement of account (+ template)

Updated 2026-06-18

At month-end, when a client has several invoices outstanding — some paid, some not — what you need isn’t another invoice but a statement of account. It lays out everything for one client in one place, making it easy for them to pay and keeping both sides’ books aligned.

What a statement of account is

A statement of account is a summary of all of one client’s charges (invoices) and payments over a period, with the current balance owed. It’s usually sent monthly and does three things:

  • Payment reminder: shows all unpaid invoices together, prompting the client to pay.
  • Reconciliation: lets both sides check the books and catch any omissions or disputes.
  • Relationship: regular statements look professional and transparent, building trust.

Statement vs. invoice

  • An invoice covers a single transaction and asks for a specific amount.
  • A statement is the full picture of multiple transactions and the overall balance — usually not itself a proof of payment.

In short: an invoice says “please pay this one”; a statement says “here’s where our account stands”.

What a statement should include

  • Your company info and the client’s name;
  • A statement number and date;
  • Line-by-line activity: date, description (which invoice or payment), charge amount, paid amount;
  • A running balance on each line — the most important column;
  • The closing balance due.

Don’t calculate the balance by hand

Adding up a running balance line by line, month after month, is tedious and error-prone. The statement of account generator calculates the balance for you and exports a PDF to send. For a single invoice, use the invoice generator.

Automate reconciliation

If you have many clients and invoices, month-end reconciliation by hand is painful. Duefy tracks each client’s outstanding balance in real time and chases overdue invoices, sparing you the month-end ledger work.
