Invoice number, dates and client reference
For the wording that accompanies your invoice, see how to ask a client for payment.
Give every invoice its own number and keep the sequence understandable to you. Put the invoice date and payment due date beside it. If the client uses a purchase order, campaign code or project reference, place that reference where accounts payable can see it without opening another file.
Your details and the billing contact
Use the business or trading name the client knows, plus a reply email and mailing address. Address the invoice to the legal client name and the person or team responsible for approving payment. A clear billing contact is more useful than sending the document to a general inbox with no owner.
Description, quantity, unit and rate
Name the delivered outcome in language the client will recognize. Then use the unit that matches the agreement: hours, words, articles, days, sessions or one project milestone. The downloadable templates include a Unit column and calculate each line from quantity × rate. The free online editor uses item descriptions, quantity and rate rather than a separate Unit field. For hourly work, add up the weekly hours first before entering the quantity, or add hours and minutes from separate sessions. Use the freelance hourly rate calculator to work out a rate for your next quote from your income goal, costs and billable hours.
Deposit paid and balance due
Show the full charge first, then record a deposit or earlier payment as its own deduction. Include the date or earlier invoice reference so the client can reconcile it. The downloadable project file calculates the remaining balance. The online editor does not currently provide separate paid and balance fields, so add that detail to the notes when using the editor.
Tax identifier placeholder
Keep one labelled place for the identifier that belongs on your document, such as ABN, UTR, VAT number or GSTIN. Choose the label that applies to your invoice rather than printing every identifier at once. The tax amount remains an editable input in the files so the template does not decide a tax treatment for you.
Payment instructions
State the payment method, account or payment-link details, accepted currency and the reference the client should include. For bank transfers, this is also where an IBAN or SWIFT/BIC can sit. Keep sensitive login information off the invoice. If you use Invosmith after signing in, you can save default payment instructions for later invoices.
