Invoice and Thermal Receipt Printing Software

Invoice, thermal receipt and service sticker printing

RMS prints A4, A5 and A6 invoices, 80 mm thermal receipts, a windscreen service sticker and 50 × 30 mm barcode labels for independent shops. Every printout shows exactly the saved figures and a QR code that tells whether the shop really issued it. Printing works without internet, from the shop's own computer.

What do you get?

Invoices on A4, A5 or A6 paper, or an 80 mm thermal receipt, chosen at setup and changeable later.

The shop's logo, details, invoice tagline, footer and bank details print on invoices.

A tax invoice with your own tax name (VAT, GST or sales tax), rate and registration numbers, with its own number series for business customers.

A windscreen service sticker with the next change km and expected date.

50 × 30 mm barcode labels with the price, from a product, the product list or a stock in.

Every printout shows the saved figures and a QR code; scanning it tells whether the shop issued it and whether it still matches, offline.

Credit notes for returns and exchanges, payment receipts with the balance, and a printed day-close cash report.

Workshop job cards, estimates and a pick list sorted by rack.

Ctrl+P prints the last saved bill again, and print-on-save can be switched on.

What can RMS print?

Printout	Used for
A4, A5 or A6 invoice	Proper bills with your logo, tagline and footer
80 mm thermal receipt	Fast receipts at a busy counter
Windscreen service sticker	Next change km and expected date
50 × 30 mm barcode labels	Price labels for shelves and stock received

Credit note, payment receipt, cash report	Returns, customer credit payments and day close

Choose the paper size at setup and change it any time in Settings. Print-on-save prints each bill as it is saved, and Ctrl+P reprints the last one.

How does the QR code stop fake receipts?

Every printout carries a QR code. When a customer brings back a receipt for a return or a warranty claim, read the code with any phone scanner and paste its text into Verify a receipt. RMS tells you whether your shop really issued it and whether it still matches your records. This works offline, so a changed amount or a receipt from another shop is caught at the counter.

Every printout shows exactly the saved figures. A corrected bill keeps its number, and the reprint shows the corrected amounts.

Does thermal receipt printing need special software?

No. RMS is the thermal receipt printing software: pick the 80 mm size and print to your receipt printer like any other printer. A4 or A5 printers work for invoices, and a label printer handles the 50 × 30 mm barcode labels, one label per page.

What goes on a tax invoice?

Enter your tax name (VAT, GST or sales tax), your rate and the shop’s tax registration numbers at setup. Tax can be included in prices or added on top. A tax invoice needs a customer with a tax registration number and gets its own number series, and amounts print in your own currency format. RMS prints tax invoices with your own tax name, rate and registration numbers, but it is not connected to any government e-invoicing or fiscal reporting system. Businesses that must report each sale to a tax authority in real time need a certified system.

Questions shop owners ask

Which paper sizes can RMS print?

A4, A5 and A6 invoices, 80 mm thermal receipts, a windscreen service sticker and 50 × 30 mm barcode labels.

What is the QR code on the receipt for?

Scan it into the Verify a receipt box and RMS tells you whether your shop issued that receipt and whether it still matches your records. It works offline.

Can I print a VAT, GST or sales tax invoice?

Yes. Enter your tax name, rate and the shop's tax registration numbers at setup. A tax invoice needs a customer with a tax registration number and gets its own number series. RMS is not connected to any government e-invoicing or fiscal reporting system.

Do I need a thermal printer?

No. Any A4 or A5 printer works for invoices. An 80 mm thermal printer is optional for quick receipts.
