One round, every period
The same four steps for a market of forty stalls or a car park of six bays.
-
1Plan
Draw the site once
Put stalls, bays and storage units where they really are. Each cell carries its code and turns green, amber or red as the period moves.
-
2Bill
Charge the way you let
Base rent, a share of turnover with a cap, metered power and fees sit on the same bill. A missing reading leaves the total blank and says what it is waiting for.
-
3Collect
Send the exact amount
The payment sheet puts the amount inside your market's code. A forwarded slip is credited by its bank reference, and the same reference never counts twice.
-
4Close
Close and carry forward
When the plan shows what is left, close the period. The history is filed and anything unpaid moves to the next period on its own.
Stalls, bays and units don't pay the same way
Every spot keeps its own charge rules, so one site can mix them freely.
Base rent
A fixed amount each period, the line most spots start with.
Turnover share with a cap
A percentage of declared turnover, never more than the cap you set.
Metered power
Enter the meter reading; Letnook works out the units and the charge.
Day pitches
A price per day for traders who come on market days only.
Late fees
Added to a spot that is overdue, on the bill where the tenant can see it.
Discounts
Take something off one period without changing the rent.

- 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.
