Getting started

Work offline and the 30-day check-in

SeroPayroll works without the internet, but must check in with the licence service at least every 30 days.

What this does

Your payroll data stays on your computer, so you can work with no internet. The licence needs to check in online about once a month to confirm it is still valid and that your computers fit the seat count.

How it works

  1. When you activate a licence, the app confirms it with the licence service.
  2. Each time the app starts and finds the internet, it checks in again.
  3. The check-in stores a date that says "next check-in by". It is 30 days after the last one.
  4. Without the internet, you can keep working until that date.
  5. After 30 days with no check-in, the app becomes read-only until it checks in.

Check in by hand

  1. Connect to the internet.
  2. Go to Settings › Licence.
  3. Under Check-in you see "Checked in {date} · next by {date}".
  4. Choose Check in now. The message says "Checked in. Next check-in by {date}".

What the check-in sends

It sends the key identifier, a computer identifier, the computer name, the platform and the app version. It sends no payroll data. See What leaves your computer, and when.

Good to know

  • Not being able to reach the service is never treated as a refusal. Only a clear "no" from the service, such as a revoked key or a full seat count, makes the app read-only at once.
  • The app also fetches a list of withdrawn keys once each time it starts and is online. It keeps the last good copy.
  • If the licence service has a problem, the 30 days count from the last successful check-in.
  • The licence end date is checked on your computer every start. A clock moved back by more than a day shows "Needs check".
  • Read-only still lets you open, view, print, export and back up.
