What every invoice should include
An invoice is a request for payment, and the clearer it is, the faster it is paid. Customers delay invoices they have to ask questions about.
- Your business name, address and contact details
- A unique invoice number that follows the last one
- The invoice date and the date payment is due
- Who you are billing, and their details
- Each item or service, quantity, price and amount
- Tax, discounts and the total due
- How to pay you: bank, account name and number
VAT on an invoice in Nigeria
If your business is registered for VAT, show it on the invoice. The standard rate in Nigeria is 7.5%. Say whether your prices already include it, so the customer can see exactly how much of the total is tax. Tick "Prices include tax" above if they do, and the tool works the tax out of the price instead of adding it on.
Numbering your invoices
Use a sequence and never reuse a number: INV-0001, INV-0002 and so on. Gaps and duplicates are what make an accountant or a tax officer ask questions. If you raise invoices from more than one place, give each its own prefix.
Getting paid faster
Put a due date on every invoice and the payment details in the notes, so the customer has nothing to look up. Short terms, seven or fourteen days, are paid sooner than "payable on receipt", which many customers read as "whenever".
When a PDF is not enough
A PDF invoice tells you nothing after you send it. You do not know if it was opened, the payment arrives as an unexplained transfer you have to match by hand, and chasing is a WhatsApp message you remember to send. That is the point where invoicing software earns its place.
Keep a copy
Save every invoice you send, even the free ones from this tool. Your draft is kept in this browser until you start again, but it is not a filing system. A record of what you billed is what your books, and any tax return, are built from.
Frequently asked questions
Is this invoice generator really free?
Yes. There is no sign-up, no watermark beyond a small line at the foot, and no limit on how many invoices you make. Everything runs in your browser.
Is my information safe?
Nothing you type is sent to us or anywhere else. The tool works entirely in your browser, and your draft is saved on your own device so a reload does not lose it.
How do I download the invoice as a PDF?
Press Download PDF, then choose "Save as PDF" as the destination in the print window. Only the invoice is printed, not the rest of the page.
Can I add my logo?
Yes. Add an image of up to 2 MB and it appears at the top of the invoice. It stays on your device and is not uploaded.
Can I invoice in dollars or another currency?
Yes. Choose naira, cedi, shilling, rand, dollar, pound or euro, and every amount on the invoice is shown in that currency.
What is the difference between an invoice and a receipt?
An invoice asks to be paid. A receipt confirms that you have been. Send an invoice before payment, and a receipt once the money has arrived.
What is the VAT rate on invoices in Nigeria?
The standard VAT rate in Nigeria is 7.5%. Charge it only if your business is registered for VAT, and show it as its own line so the customer can see it.
