What Flatpay works with
Does Flatpay work with your software?
Flatpay names few integrations. Its own help centre documents a Google and website ordering link, kitchen and bar printers, and Shopify, Magento 2 and PrestaShop for online payments. Automatic accounting links are listed for Danish software only, and it does not list Xero, QuickBooks, Deliveroo, Uber Eats, Just Eat or booking apps. Ask on your quote about anything you rely on.

Google (Order online)

Online shop
Shopify
With limitsFor online payments, yes: Flatpay's help centre explains connecting Shopify to Frisbii (Flatpay's online payment platform) with an API key. That is for taking payments on your web shop, not for syncing your shop stock with the in-store POS. source
WooCommerce
Not listedNot listed. Flatpay's help centre covers Shopify, Magento 2 and PrestaShop for online payments, but not WooCommerce. source
Your own website (WordPress, Wix, Squarespace)

Booking
Fresha
Not listedNot listed. Flatpay does not advertise booking or deposits. Salons keep their booking app for bookings and deposits and use the Flatpay terminal for payment in the salon. source

OpenTable and table booking
Not listedNot listed. Flatpay's POS has a table view and split bills, but reservations stay in your booking system. source
Payments
Stripe
Not listedNo. Stripe is a separate payment provider. Flatpay's online payments run on its own platform (Frisbii), so you would not use both for the same payments. source
Kitchen and bar printers
DocumentedYes. Flatpay's POS sends orders to standalone kitchen and bar printers over the internet: you enter the printer's serial number in the portal, with no direct wiring. source
Another till or POS system
With limitsOnly case by case: Flatpay says integration with other POS providers is possible only if Flatpay confirms it after a review. Ask before you sign if you want to keep your current till. source
