Fix common problems in InvoiceStamp
Last updated · InvoiceStamp 1.1.0 for iPhone and Android
Most problems in InvoiceStamp come down to the connection, a PDF that's still being made, or a permission on your phone. Find the message you see below: each one says what it means and what to do. If yours isn't here, or the fix doesn't work, contact support with a screenshot.
Why does the app say "You're Offline"?
InvoiceStamp needs an internet connection: your documents, clients and PDFs are kept in your account, not only on the phone. When the connection drops, a You're Offline screen covers the app and shows Waiting for connection….
Turn on Wi-Fi or mobile data, or move to a better signal. The screen clears on its own as soon as you're back online; there's nothing to tap.
What does "Saved to Queue" mean?
You saved a document as the connection dropped. It's kept on your phone and will be saved to your account, and its PDF made, automatically when the network comes back. Tap View in Queue to see it in Documents, where it's marked Queued, or Done to carry on.
Don't sign out while documents are queued: signing out clears changes that haven't synced yet.
Why is my PDF taking so long?
Making a PDF usually takes a few seconds. After about five, the dialog reads "Still rendering your PDF — this can take a moment…". If it takes too long, you'll see:
The PDF is taking too long to render. Your document is saved — try sharing again in a moment.
Your document is safe. Wait a moment, then tap Share (or Download PDF) again.
What if InvoiceStamp couldn't render the PDF?
We couldn't render this PDF. Try again, or switch to another design.
Tap Share again first. If it fails again, open the Design card in the editor, pick another design, and try once more. If a design keeps failing on a document, tell us which design and document number.
On the View PDF screen, the same problem shows as "PDF generation failed. Try again." or "Generation timed out. Try again.".
Why did saving fail?
Failed to save document usually means the connection dropped or the server didn't answer. Check your connection and tap Save again: your document is still in the editor.
Two messages say more:
| Message | What to do |
|---|---|
| This client was deleted. Choose a client again and try once more. | Tap Your Client and pick or create the client again. |
| Our servers had a problem. Please try again in a moment. | Wait a minute and save again. |
If Save or Preview looks dimmed, something required is missing. The line above the buttons says what, such as "Add client details to continue" or "Give item 2 a price to continue", and tapping the button scrolls to it.
Why hasn't my verification email arrived?
It can take a minute. Check your spam or junk folder, then tap Resend email on the Check your inbox screen (it's available again 60 seconds after each send). If the address is wrong, tap Use a different email. See Sign in and passwords.
Why was I signed out with "Signed out on this device"?
Your subscription covers 3 devices at a time. Signing in on a fourth signs out the one used least recently. Tap Sign in again to use this device; that signs out another one.
What do the update messages mean?
- Update available is a banner with the new version number. Tap it to open the App Store or Google Play and update, or tap ✕ to hide it for a day.
- A full screen with Get the New Version means this version of InvoiceStamp is no longer supported. Tap the button to update in the App Store or Google Play; the app closes once the store opens.
Why does it say "Save folder is no longer accessible"?
The folder you chose in Save Location was moved, renamed or deleted, the app lost access to it, or iCloud Drive isn't available. Your PDF was saved to the default folder instead: on iPhone, Files › On My iPhone › InvoiceStamp; on Android, the phone's Documents folder. Pick a folder again in Profile → Settings → Save Location. See App settings.
Why can't I load a client from Contacts?
Contacts permission denied means InvoiceStamp isn't allowed to read your contacts. On iPhone, open the Settings app → Apps → InvoiceStamp → Contacts and allow access; on iOS 17 and earlier, InvoiceStamp is listed directly in Settings. On Android, open Settings → Apps → InvoiceStamp → Permissions → Contacts and choose Allow. Then tap Load from Contacts again.
Why does the plans screen open and not close?
Your subscription has ended (or a payment failed and wasn't fixed), so InvoiceStamp shows the plans screen until you have an active plan. Your documents are still in your account. You can:
- choose a plan;
- tap Restore purchases if you subscribed before with this Apple ID or Google account;
- sign out with the line under the button, if you're signed in with the wrong account.
If you're sure your subscription is active, tap Restore purchases first. See Your subscription.
Still stuck?
Contact support with your phone model, the app version from the bottom of Settings, and a screenshot of the message.
