Yes. Xero has always been a website rather than an installed program, so it works on Linux exactly as it did on Windows. Xero lists Chrome, Edge, Firefox and Safari as supported, and the first three are all available on Linux.
Xero by Xero Limited · Business & accounting · Works in a browser
This is the easy one. Xero has no desktop version to miss. You sign in at xero.com in a browser and
every screen, report and bank feed behaves the way it always did. Nothing is installed, nothing is
converted, and there is no company file sitting on your hard drive to worry about.
Xero's own requirements page lists Google Chrome, Microsoft Edge, Mozilla Firefox and Apple Safari.
Chrome, Edge and Firefox all have proper Linux versions, and Firefox usually comes preinstalled, so
you are covered before you do anything. An internet connection is required, as it was on Windows.
Your data lives on Xero's servers, so there is nothing to move. Sign in on the Linux machine and
it is all there. This is the part of switching that cloud accounting quietly made painless.
Two small things to check. If you print or email invoices to a specific printer, test that once on
the new machine. And if you used a Xero add-on that needed a Windows program on your computer, such
as some payroll or point of sale connectors, confirm that piece separately, because the add-on may
have requirements Xero itself does not.
Only worth considering if you want to stop paying a subscription. Free and installed on your own machine, but you lose live bank feeds and do the importing yourself.
Your files: Imports CSV, QIF and OFX exports from Xero. Categories and tax codes will need checking.
