Charge rules

Petak lets each spot carry the way you actually let it. Fixed rent is only one line; the rest can follow the site and the market.

WHAT A SPOT BILL CAN CONTAIN Base rent 850.00 Turnover share 20.00 Power — units × rate 665.00 Day pitch 17.20 Late fee or discount − 50.00 Brought forward + 120.00 Due 1,622.20 A missing input leaves the total blank until you provide it.
Charge lines remain visible so the amount can be checked.

Base rent

Use a fixed amount for a recurring letting charge. It can be billed even when the spot also has a turnover share, power, day count or adjustment.

Turnover share with a cap

Set a percentage and a maximum amount. Petak applies the percentage to the declared turnover, then stops at the cap. For example, 8% of 50,000 is 4,000; with a 3,000 cap, the line is 3,000. The turnover must be declared before the bill can have a total.

Power and day pitches

A metered power line is the current reading minus the previous reading, multiplied by the rate. A day pitch uses its rate and the number of days. Both inputs remain inspectable on the spot.

Late fees and discounts

Add a one-off late fee as a positive adjustment or a discount as a negative adjustment. The adjustment is for the current period and is cleared when the period closes.
