How it works

One round, every period

The same four steps for a market of forty stalls or a car park of six bays.

    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.

    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.

    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.

    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.

Built for mixed letting

Stalls, bays and units don't pay the same way

Every spot keeps its own charge rules, so one site can mix them freely.

฿8,500 / month

Base rent

A fixed amount each period, the line most spots start with.

8% · cap ฿4,000

Turnover share with a cap

A percentage of declared turnover, never more than the cap you set.

฿7 / unit

Metered power

Enter the meter reading; Letnook works out the units and the charge.

฿300 / day × 12

Day pitches

A price per day for traders who come on market days only.

+฿200

Late fees

Added to a spot that is overdue, on the bill where the tenant can see it.

−฿500

Discounts

Take something off one period without changing the rent.
