Troubleshooting

Fix common issues, from a slow app to a till that can't find the server.

Maintained by , Founder · Updated

The App Feels Slow

  • EVRST runs locally, so it should be snappy even offline

  • If slow, check if you have thousands of invoices and a weak filter

  • Close other apps to free up RAM

  • Restart the app and try again

I Cannot Find a Past Invoice

  • Use the search box or filter by customer and date range

  • Check if it is marked as Draft (might not appear in some views)

  • Check if it is archived or deleted (check the trash if available)

A Payment Is Not Showing on the Invoice

  • Check that you recorded it against the correct invoice

  • Verify the date and amount

  • Look in the invoice detail - scroll down to "Payments" section

  • If still missing, check the Audit Log to see what happened

Stock Numbers Do Not Match My Physical Count

  • Do a recount to confirm the physical number

  • In EVRST, navigate to the item

  • Click Adjust Stock

  • Enter the difference

  • Add a note (e.g., "Physical count 2026-06-23")

  • Save

The stock is now corrected and the adjustment is logged.

My Printer Is Not Printing Clearly

  • In Design Studio, reduce the font size or adjust margins

  • If using a thermal printer, check that your label width matches the template

  • Print a test page on actual paper before running large batches

  • Consider having a PDF alternative for records

I Lost My Password

  • On the login screen, look for "Forgot Password" or contact your admin

  • Admins can reset passwords in Settings > Team & Permissions

  • Keep a written backup of your primary admin password in a safe place (locked drawer, safe, etc.)

A Cashier Till Cannot Find the Main Server

Work down this list:

  • Is the Main Server PC switched on and awake? Check its power settings so it does not sleep during business hours.

  • Are both PCs on the same network? A till on guest Wi-Fi cannot see the server.

  • Has the server’s IP address changed? This is the usual culprit after a router restart. Give the Main Server a fixed local IP to stop it happening again.

  • On the till’s Connect to your server screen, try Search network first, then enter the address by hand if the search finds nothing.

  • Did anyone change the port during a reinstall on the Main Server? The tills must use the same port the server is listening on.

Work already saved is safe. A till holds no data of its own, so losing the connection interrupts the till but never loses anything that was saved.

The App Says My License Is Locked

The message on screen tells you which of these it is (see "When the App Is Locked" earlier in this guide). Whatever the cause:

  • Your data is safe and untouched. Nothing is deleted.

  • The download a backup button on that screen still works, so you can take a copy of everything before doing anything else.

  • If you have a valid license key, enter it there and you are back immediately.

  • If you believe the lock is a mistake, contact support. The email button on that screen pre-fills the reason so we can look it up quickly.

I Lost My License Key

On the activation screen, use Forgot your license key? Look it up by email with the address you bought it with.

I Changed My PC or Replaced the Hard Drive

Your license is tied to the machine it was activated on. Install EVRST on the new PC, activate with the same key, and restore your backup. If activation reports that the license is already in use, contact support and we will release the old activation for you.
