What to include on a professional invoice
A clear invoice leaves no room for questions and gets paid faster. Every invoice you send should carry:
The word "Invoice" and a unique invoice number, so both sides can reference it later.
Your business details: name, address, email, phone, and your logo if you have one.
Your client's details: who the invoice is billed to.
Issue date and due date, so the payment deadline is unambiguous.
A line-by-line breakdown: description, quantity, rate, and amount for each item or service.
Subtotal, tax, any discount, and the total due, with the currency clearly shown.
Payment terms and accepted payment methods.
This generator lays all of it out for you, so a complete, professional invoice takes a minute instead of an afternoon.
How to number your invoices
A consistent invoice number keeps your records tidy and makes tax time far easier. Pick one pattern and never reuse a number:
Sequential
INV-0001, INV-0002, INV-0003. Simple and hard to get wrong.
Dated
2026-001, 2026-002, resetting each year so the year shows at a glance.
Client-based
ACME-001 when you want to group invoices by customer.
Whatever you choose, keep the format the same every time. Gaps or duplicates make a missing payment hard to spot.
Invoice payment terms, explained
Payment terms tell your client exactly when payment is due. The common ones are:
Due on receipt
Payment is expected as soon as the invoice arrives.
Net 7, 15, 30
Payment is due within 7, 15, or 30 days of the invoice date.
Deposit or milestone
Part upfront, the rest on completion, common on larger projects.
State the terms on every invoice and agree them before you start work. A shorter term and a clear due date tend to get you paid sooner.
Keep the credit note tied to the invoice
This tool makes the document. A free Billbooks account keeps it linked to the invoice it corrects, so the balance updates itself and neither side has to do the maths twice.
Correcting an invoice you already sent, without tearing up the audit trail.
A credit note is a document a seller issues to reduce or cancel an amount a buyer already owes on an invoice, without deleting the original invoice. It leaves the original in place and records the correction separately, which is what keeps the audit trail intact for both sides.
Once an invoice has been sent, issue a credit note rather than editing it. In most jurisdictions a sent invoice is a legal record and changing it breaks the sequence your books and your client's books both rely on. Common triggers are returned goods, a billing error, a cancelled order, an agreed discount, or damaged items.
Not necessarily. A credit note records that the amount is owed back to the customer. Whether it is refunded or applied against their next invoice is a commercial decision between you and them, so it is worth stating which one you mean in the notes.
Your details and the customer's, a unique credit note number, the date, the number of the invoice it corrects, the items or services being credited with amounts, any tax being reversed, and the total credited. Referencing the original invoice is the part people most often leave off, and it is the part that makes the document usable.
No. A credit note is issued by the seller and reduces what the buyer owes. A debit note is usually issued by the buyer to request that reduction. A refund is the payment that may follow a credit note, and it is a separate transaction.
Yes. Create and download as many credit notes as you like, with no signup, no watermark, and no card. A free Billbooks account adds the part this tool cannot do: keeping the credit note linked to the invoice it corrects so the balance updates itself.
