Troubleshooting

The problems people meet most, what causes each one, and where to fix it.

Bills and statuses

A new stall says Not billed yet.

In most markets a new stall starts with a revenue share and metered electricity. Open it and record the reading and declare the turnover, or remove those lines in Edit space if the stall does not pay them.

Record payment is missing.

The space is already paid, vacant, still waiting on a reading or turnover, or its total is zero. The space screen says which.

Save stays grey when I enter a meter reading.

The number is lower than the previous reading, or blank. A meter only counts up; if it was replaced, set the Carried-over reading in the space's editor first.

A space turned overdue on the due day itself.

Letnook counts an unpaid bill as overdue from the day set in Settings → Site → Rent falls due on day. Move the day if you give tenants longer.

Getting paid

A payment method is greyed out.

Its details are not filled in. Add your ID or bank details in Settings → Getting paid; the line under that group says which methods are ready.

A slip will not read.

Read a slip needs the QR code on the slip screenshot. If there is none, or it says No code could be read from that image, check the transfer in your banking app and record it from the payment sheet.

It says the reference was already credited.

That slip has already been credited to a space. Check Collect's Paid filter; if it went to the wrong space, open that space and choose Undo payment, then credit it again.

I recorded a payment by mistake.

Open the space and choose More actions → Undo payment. This works for the current period.

Periods and tenants

Close the period is unavailable.

A let space is Not billed yet. The confirmation lists the codes; record their readings or turnover, then close.

I cannot remove the tenant name.

A tenancy ends with Move out, not by clearing the name. Move out settles the deposit and keeps the record.

I cannot remove a zone.

It still has spaces. Move them to another zone in their editor, or delete them, then remove the zone.

I cannot change the currency.

The market is fixed once spaces exist, so every amount keeps its currency. It can only be chosen during setup.

Sync, backups and Pro

Documents are missing on my other device.

Scans are not synced; they live on the device and in backups. Restore a backup on the other device to bring them over.

iCloud sync says Off.

The device is not signed into iCloud. Turn iCloud on in the device's own Settings; until then the book stays on this device only.

It says there is too much data to sync.

Open Settings → Data and use Compact the synced book, which moves older records to the device's archive without deleting anything. Build a workbook to keep a copy.

Pro is not showing on a new device.

Use Settings → Pro → Restore purchases while signed in with the Apple Account that bought it.
