Make a proper bill in 5 seconds: receipts and invoices for Sri Lankan businesses
Handwritten bills look unprofessional, Excel takes too long and paper receipts get lost. A digital bill with your logo, a QR code to your page and a clear total takes seconds to make, and your customer can keep it forever.
Why a proper bill matters
- It builds trust. A clean bill with your name, address and phone looks like a real, established business.
- Fewer arguments. Every item, discount and charge is written clearly, so there is no confusion about the total.
- Faster payment. Add your bank details and a pay-by date, and customers know exactly how to pay.
- Repeat customers. The QR code on the bill brings people back to your page to order, book or leave a review.
What goes on a good bill
- Your logo and business name, address and phone number.
- A bill number and the date (for example BL-0007).
- The customer's name and phone number.
- Each item with quantity, price and amount.
- Discount, service charge and tax, if you use them.
- A clear total, and whether it is paid or not paid yet.
- How to pay (bank details) and a short note, such as warranty terms.
How to make a bill in 5 seconds

The bill is the same 80 mm width as a supermarket receipt, in sharp black and white, so it looks great on a thermal receipt printer at the counter. On a computer or phone, choose Save as PDF to keep a copy or attach it to an email.

Questions people ask
Can I print the bill on my receipt printer?
Yes. The bill is made in the 80 mm size that most thermal receipt printers in Sri Lanka use, in black and white so it prints sharp. You can also save it as a PDF and print it on any printer.
Does my customer need an app to see the bill?
No. They get a private link by email or WhatsApp. It opens in the browser, and they can print it or save it as a PDF.
Can I add a discount, service charge or VAT?
Yes. Add a discount amount, a service charge percentage and a tax percentage. The total is worked out for you.
