What we can help with
Quick checks before contacting us
Protect your records. Create an encrypted backup before reinstalling, resetting or replacing a device.
Confirm the basics. Check internet access, device date and time, available storage, selected business and signed-in account.
Reopen safely. Close and reopen Arthium once. Do not repeatedly submit a payment, invoice or restore operation while its result is uncertain.
Collect useful details. Note the app version, device model, Windows or Android version, exact time, action performed and visible error message.
Send a useful support request
Include: business name, registered email, Arthium version, device type, affected module, steps that caused the issue and a screenshot with customer or financial information hidden.
For printing: include printer model, driver name, paper size, print profile and whether Windows test print works.
