Example: a filled Cooking Gas Invoice
A restaurant takes 150kg of gas in a month and two new cylinders. The gas plant sends one invoice due within 7 days.
LPG refill (per kg): 150 x ₦1,300 = ₦195,000
12.5kg cylinder (new): 2 x ₦45,000 = ₦90,000
Delivery: 1 x ₦5,000 = ₦5,000
Total: ₦290,000. These amounts are examples; use your own prices.
Common mistakes to avoid

How gas plants and gas retailers use an invoice
Gas plants supply restaurants, hotels, schools and canteens in bulk, often weekly. These customers pay on invoice, sometimes at month end, so you need a record of each supply and the price per kg on that day.
Writing the items on a cooking gas invoice
List each item or service on its own line, for example LPG refill, 12.5kg cylinder, Delivery, with the quantity and the price for one unit. The generator adds up each line and the total due. Below the items, add the date you expect payment and your bank details, so the customer can pay the moment they open the invoice.
Tips for gas plants and gas retailers
- Write the kg supplied and the price per kg.
- List new cylinders separately from refills.
- For weekly customers, send one invoice for the month with each date.
Following up until you are paid
Put a clear due date on every invoice. If the date passes, send a short, polite reminder on WhatsApp with the invoice attached. When the customer pays, give them a receipt, and if they pay only part, give a part payment receipt showing the balance.
Frequently asked questions
How do I bill a restaurant for weekly gas?
List each delivery with date and kg, or send one monthly invoice with all deliveries and a due date.
Should the invoice show the price per kg?
Yes. Gas prices change often, so the price on the day protects both sides.
Do I need to charge VAT on my invoice?
Only if your business is registered for VAT. The VAT option adds 7.5% for you. If you are unsure, check with your accountant.
