What can I put on an invoice?
Customer details, itemized lines (quantity, unit, rate, description, SKU), tax percentage with a custom label, discount percentage, shipping, reusable adjustments, notes, payment terms, issue and due dates, your branding and an automatic document number.
How does invoice numbering work?
Each document type has its own sequence with a configurable prefix (INV by default). Numbers advance automatically and sequences run per year. The next number is previewed in settings.
Can I change the invoice number format?
You can set your own prefix per document type. The sequential counter and year handling are automatic so numbers stay unique and ordered.
How do due dates and overdue tracking work?
Set a due date when you create the invoice. Overdue invoices are counted on the dashboard, so unpaid work surfaces itself instead of hiding in a list.
Can I duplicate an invoice?
The fastest way to repeat billing is a recurring schedule, or converting from an existing quotation. Products and customers are reusable records, so re-creating a similar invoice takes seconds.
Can I edit an invoice after creating it?
Yes — open it in the editor, change what you need, and the preview updates. Statuses let your team see whether it has already been sent.
How do I mark an invoice as paid?
Change its status to Paid — or convert it to a receipt in one click, which both records the payment document and preserves the link back to the invoice.
Can I add shipping charges to an invoice?
Yes, there is a dedicated shipping field in the totals, alongside tax, discount and adjustments.
What are adjustments?
Reusable additions or deductions — fixed amounts or percentages — that you define once and apply to any document. Useful for things like rush fees, service charges or negotiated rebates.
Can I write notes or payment terms on the invoice?
Yes. Notes and terms print in a dedicated area at the bottom of the document in every template.
Can I create an invoice for a client in another country?
Yes — use any currency, rename the tax label to match their jurisdiction, and share by public link so they do not need an account to view it.
Does InvoiceZeo calculate totals automatically?
Yes. Subtotal, tax, discount, shipping and adjustments are computed live by the app. You never type a total by hand.
