How to create an invoice for free (what to include + template)
24 September 2026 · 5 min read
Everything a professional invoice needs — invoice number, dates, line items, payment terms — and how to create and send one for free.
What every invoice must include
Missing details are the most common reason clients pay late. Include all of these every time:
- Your name or business name and contact details
- The client's name and company
- A unique invoice number (e.g. INV-0012)
- Issue date and due date
- Each service or product with quantity and price
- Subtotal, tax (if any) and total
- How to pay: bank account, wallet or payment link
Set clear payment terms
Write the due date as a date, not just 'Net 15'. State late-payment terms politely if you use them. Agree terms with the client before you start the work.
Create and send it for free
In Rupaira you can add a client, create an invoice with line items, download a PDF or share a link — free. The invoice stays linked to the client, so you always know who has paid and who hasn't.
After sending
Mark the invoice as sent, set a reminder for the due date and follow up the next working day if it isn't paid. Record the payment when it arrives so your income is always accurate.
