LalaPos is built to remove exactly this friction when a customer asks for an invoice at checkout.
During a rush, the cashier has to stop and ask for the tax code and company name, and the queue gets longer
Customers scan the QR code and fill in the details on their own phone — the cashier serves the next customer immediately
Handwritten invoice details on paper are prone to typos and wrong tax codes, meaning repeated corrections
Customers enter and double-check their own details before submitting, cutting transcription errors almost entirely
Customers forget to ask for an invoice at the moment of payment, then have no idea who to contact afterward
The QR code is printed on every receipt — customers can scan it any time within 60 minutes of the purchase
New staff have to memorize a multi-step invoicing process and easily miss a step or a field
The whole process runs automatically from the moment the receipt prints to the moment the request arrives — staff have nothing extra to do
Everything you need for invoicing without asking a single question
Built for customer self-service, so cashiers lose no extra time at the counter.
Automatic QR code on every receipt
No extra setting to turn on — every receipt LalaPos prints already carries a QR code linking straight to the invoice-detail form for that exact order.
No app to install, no login required
Customers just point their phone camera at the code and the page opens right in the browser — no app download, no account needed.
Supports both personal and business invoices
Customers pick the invoice type themselves: personal (name, phone number) or business (tax code, company name), all on the same screen.
Link expires automatically after 60 minutes
Each QR code stays valid for only 60 minutes after printing, limiting the risk if a paper receipt is lost or seen by someone else.
Requests land straight in your pending list
Whatever the customer submits is recorded in the system immediately — the shop owner just opens the e-Invoice section to issue it, with nothing to track down manually.
Syncs with compliant e-invoicing
Works directly with the tax-authority-coded e-Invoice feature — no need to re-enter the same information a second time.
Up and running in 4 steps
No complex setup, no extra staff training.

What shop owners say about QR invoice scanning
“During rush hour the line used to get long every time I stopped to ask for a tax ID — that ate up almost a minute per customer. Now they scan the code on their own receipt and I can focus on serving people faster.”
Emily Carter
Owner, Carter's Coffee House – Austin, TX
“Customers used to call back asking for a business invoice after they'd already left. Now they scan the code within 60 minutes and it's done — no more phone calls chasing down details.”
James Whitfield
Manager, Whitfield Corner Market – Chicago, IL
“New hires don't need to learn a complicated invoicing process — the system handles it, and customers fill in their own information themselves.”
Sophie Bennett
Owner, Bennett & Co. Boutique – New York, NY
