A clear invoice helps a customer identify the work, match the amount to the agreement and process payment. A generator can organise the document, but you remain responsible for the accuracy of the amounts and any local invoicing requirements.
A practical workflow
- Record the business details, customer reference, unique invoice number, issue date and payment due date. Include only the identifying details actually needed for the transaction.
- Describe line items so the buyer can recognise what was supplied. Check quantity, unit price, discount and any tax treatment against the agreement and relevant requirements.
- Review the total, currency code, payment instructions and contact for questions. Export a readable copy, send it through the agreed channel and record delivery and payment status.
Worked example
For an illustrative invoice, two design sessions at USD 150 each give a subtotal of USD 300. Any discount or tax should be shown separately using the applicable calculation. Explicit 'USD' avoids confusion where a dollar sign could mean several currencies. A purchase-order reference can help the client's finance team match the invoice.
What to check before sharing
Never guess a tax rate, invent a registration number or add an unagreed late fee. Consult the relevant tax authority or adviser for the rules applying to your business.
Is an invoice the same as a quotation?
No. A quotation describes a proposed price and scope; an invoice requests payment for the agreed transaction. Use references that connect the two without confusing their status.
