Types of Invoices in Nigeria: Examples and When to Use Each
The right document depends on what has happened in the transaction. A standard invoice may be enough for a completed service, while a deposit, recurring contract or international shipment may need a different format.

1. Standard invoice
Use a standard invoice for an ordinary sale or service. It should identify the seller and customer, describe the work, state the amount and give a payment deadline.
Example: A designer invoices ₦350,000 after completing a company profile.
2. VAT invoice
A VAT invoice shows the taxable subtotal, VAT rate, VAT amount and total separately. Use it only where the supplier is required to charge VAT and the supply is taxable.
Check the numbers with our VAT calculator and review the VAT invoice format.
3. Pro forma invoice
A pro forma invoice gives the customer preliminary pricing and transaction information. It is useful before the final invoice but should be clearly labelled so it is not mistaken for a completed sale.
Read the pro forma invoice guide.
4. Deposit invoice
Use this to request an upfront amount before work starts. Show the full project value, deposit due and remaining balance.
Example: Project value ₦1,000,000, deposit 50%, amount now due ₦500,000.
5. Interim or progress invoice
This supports milestone billing. It should explain the completed stage and how the amount relates to the full contract.
6. Final invoice
The final invoice closes the project. It should show previous deposits or interim payments so the customer can understand the balance.
7. Recurring invoice
Use recurring invoices for retainers, subscriptions, rent or maintenance contracts. Keep the billing date and service period clear.
8. Commercial invoice
A commercial invoice is commonly used for goods moving across borders. It can include customs information, country of origin, shipping terms and detailed product values. It is not simply a more formal name for every business invoice.
9. Credit note
A seller may issue a credit note to reduce or cancel part of an earlier invoice, for example after a return, overcharge or agreed discount. Link it to the original invoice.
See our credit-note guide.
10. Debit note
A debit note records an adjustment, but its meaning depends on who issues it and why. Explain the reason and reference the original transaction. Read our debit-note guide.
11. Receipt
A receipt is not another invoice type. It confirms that the customer has paid. Use the free receipt generator after receiving payment.
Which invoice should you choose?
Ask four questions:
- Has the sale happened?
- Are you requesting or confirming payment?
- Does VAT apply?
- Is the transaction local, recurring, staged or international?
If you simply need to bill for completed work, start with a standard invoice. You can create one online or use a free Nigerian template.
Frequently asked questions
Is a quotation an invoice?
No. A quotation presents a proposed price before acceptance. An invoice requests payment under the agreed transaction.
Can one invoice request a deposit and show the full value?
Yes. Clearly distinguish the total contract value, amount currently due and future balance.
Should every invoice include VAT?
No. Confirm the supplier's obligation and the tax treatment of the supply before adding VAT.
