Getting help
The manual follows the work: set the site up, let a space, bill it, collect, close the period, and keep the book safe. Start with the questions below, or open the manual.
Common questions
- Do I need an account?No. Letnook has no account and no server. The book stays on your device and in your own iCloud.
- What does it cost?Letnook is free for up to 25 spaces. Pro adds unlimited spaces, iCloud backups and Excel export, monthly or yearly; the App Store shows the price.
- Why does a bill have no total?It is waiting on a meter reading or a turnover declaration. Letnook never counts a missing input as zero.
- How do tenants pay?The payment sheet shows a QR code with the exact amount in your market's system, your own QR, your bank details, or you take cash.
- Can a forwarded slip be credited twice?No. Read a slip takes the bank reference from the slip's QR code and refuses a reference that was already credited.
- What happens to rent that is not paid?When you close the period it becomes arrears. It stays on Collect and on the space until it is paid, or is settled from the deposit at move-out.
- How do I end a tenancy?Use Move out on the space. It settles the final bill against the deposit, records deductions and works out the refund.
- How do I keep a backup?Anyone can build a one-file backup. Pro backs up to your iCloud Drive automatically and keeps ten restore points.
- Can I use it in English and bill in baht?Yes. The interface language and the market are separate choices; the market is set once, during setup.
- Does it work on iPad and in dark mode?Yes. It follows the device's appearance, and on iPad shows the plan and a space side by side.
Troubleshooting
The problems people meet most, and the page of the manual that fixes each.
- A space is stuck on Not billed yetRecord its meter reading or declare its turnover, or remove the line it does not pay.
- A payment method is greyed outIts details are missing. Add them in Settings → Getting paid.
- A slip will not readRead a slip needs the QR code on the slip. Without one, record the transfer from the payment sheet.
- Close the period is unavailableA let space still needs a reading or turnover. The confirmation lists which.
- Documents are missing on another deviceScans are not synced. Restore a backup on that device to bring them over.
- Something elseEvery common problem, its cause and its fix, in one page of the manual.
