eTIMS guide

eTIMS app not opening is frustrating when you are mid-sale and a customer is waiting, but it is almost always fixable in a few minutes. It means the eTIMS app fails to launch or closes unexpectedly when you try to use it. This guide explains why it happens, how to fix it step by step, and how to stop it from happening again, in plain language for a Kenyan business.

Quick answer

If the eTIMS app will not open or keeps crashing, update it to the latest version, restart the device, free up storage, and clear the app cache. If it still fails, reinstall it and sign in again. Your data and pending invoices are tied to your account, not lost with a reinstall.

Key takeaways
  • eTIMS app not opening usually has a small number of specific causes, each with a clear fix
  • Work through the causes in order; most are resolved in a few minutes without calling KRA
  • Recording sales offline and syncing later prevents the most common transmission-related failures
  • A POS that handles eTIMS natively, like Veira, avoids most of these errors at the source

Why eTIMS app not opening happens

eTIMS app not opening is not random. It comes from one of a few specific causes, and once you know which one you are looking at, the fix is straightforward. Here is how the problem usually shows up first:

- The app closes immediately on opening

- A frozen or blank screen

- It started after a device or app update, or when storage got low

Match what you are seeing to the closest description above, then work through the fixes below in order, starting with the most common.

eTIMS app not opening is rarely random; match the symptom to the cause and the fix is usually minutes away.

How to fix eTIMS app not opening

Work through these in order. Most businesses resolve it at step one or two, without contacting KRA.

  1. 1

    Update the app and restart the device

    An outdated app version is a frequent cause of crashes. Update to the latest version from the app store, then restart the device so the update takes effect cleanly.

  2. 2

    Free up storage

    A device very low on storage cannot run apps reliably. Clear space by removing unused files or apps, then try again.

  3. 3

    Clear the app cache

    A corrupted cache can stop an app opening. In the device settings, clear the eTIMS app cache (not the data), then reopen it.

  4. 4

    Reinstall as a last step

    If it still fails, uninstall and reinstall the app, then sign in. Your account, history and pending invoices are stored against your account and sync back, so a reinstall does not lose them.

What not to do

Do not stop issuing receipts while you fix it

Use a backup method or another device to keep recording sales so customers still get receipts.

Do not clear app data carelessly

Clearing cache is safe; clearing all app data can sign you out and remove local settings. Start with cache only.

A worked example

Worked example

A shop assistant in Nakuru found the eTIMS app crashing every morning. The owner feared a phone fault.

The phone storage was nearly full from photos and downloads. After clearing space and updating the app, it opened normally. They set the phone to back up photos to free storage automatically, and the crashes did not return.

Most app crashes trace back to an outdated version or low storage, both quick to fix.

Business impact

Trading without eTIMS-compliant tax invoices risks KRA penalties, blocked VAT input claims for your customers, and receipts a business buyer cannot expense.

Veira signs every sale to KRA eTIMS automatically, so each receipt is compliant the moment it prints, with no separate device to reconcile.

How Veira keeps this from happening

Veira handles eTIMS natively at the point of sale, so the conditions that cause eTIMS app not opening are managed for you. It validates the invoice before it is sent, records sales offline when the network drops and transmits them to KRA when the connection returns, and keeps your KRA details in order so the common causes never arise.

When something does need attention, Veira flags it in plain language with the next step, and local support is on hand rather than a queue. See how Veira works and book a free demo. It runs from KES 2,999 a month with a free terminal.

Frequently asked questions

Why does the eTIMS app keep crashing?
Usually an outdated app version, low device storage, or a corrupted cache. Update the app, restart the device, free up storage and clear the app cache. If it still crashes, reinstall it and sign in again.
Will I lose my invoices if I reinstall the eTIMS app?
No. Your account, history and pending invoices are stored against your account, not only on the device, so they sync back after you reinstall and sign in. A reinstall is a safe step when other fixes fail.
The eTIMS app opens then closes immediately. What now?
Update it, restart the device, and clear the app cache in device settings. A blank or instantly closing screen is often a cache or version problem. If those do not work, reinstall the app and sign in again.
How do I keep selling if the app will not open?
Use another device or a backup method to keep recording sales so customers still receive receipts, then reconcile once the app is working. A POS that runs across devices avoids being stuck on one phone.
Does Veira run more reliably than the standalone app?
Veira is built for the shop floor, runs on a free terminal and across devices, and works offline, so a single phone problem does not stop you selling or issuing compliant receipts.

eTIMS app not opening is almost always one of a few known causes, each with a quick fix, so do not panic if you hit it during a sale. Work through the steps above, and if you would rather not deal with eTIMS errors at all, Veira handles compliance natively so most never happen. See how Veira works and book a free demo. Always confirm current KRA processes at kra.go.ke, as rules can change.
