Collect what is due.

Petak is rent collection for spots: market stalls, parking bays and storage cages. Your floor plan is a map, each cell coloured by one fact, so the whole site reads at a glance.

The number is never guessed

A bill waiting on an unread meter shows no total. Petak tells you exactly what it is waiting for, then adds the reading to the same bill as base rent and every other charge.

The finished bill can carry a payment code with the amount already inside it.

The monthly round
  1. 1Map

    See every spot

    A floor plan puts market stalls, parking bays and storage cages where they actually are. Each cell shows one payment fact: paid, due or overdue.

  2. 2Bill

    Use the rule that fits

    Base rent, a share of turnover with a cap, metered power, day pitches, late fees and discounts all belong on the same spot. A missing input leaves the total blank and names what is missing.

  3. 3Collect

    Put the amount in the code

    PromptPay, QRIS, Pix, VietQR or KHQR can carry the exact amount. Use your own banking-app code elsewhere, then credit a forwarded slip by its bank reference.

  4. 4Close

    Start the next period

    The collection round shows what remains, a close files the period, and the ledger carries the unpaid balance forward without losing the history.

Four steps, repeated for every period and every spot on the plan.

A floor plan, not a list

The plan is the first screen. Each spot is a cell coloured by payment status, so you can see the collection round before opening a single detail.

Compare metered power to spot and catch a reading or charge that needs attention.

Built for real sites

A ledger you carry, not a platform you operate

One map for every spot

Market stalls, parking bays and storage cages use the same plan, collection round and payment sheet. Only the identifying details change.

No account or server

The book lives on the device and in the owner's own iCloud. There is no Petak account, no Petak server and nothing to sign in to.

Made for mixed letting

Use base rent, a capped share of turnover, metered power, day pitches, late fees and discounts on the same site.

The important edge cases

The book refuses to hide uncertainty

No silent zero

A bill waiting on an unread meter or undeclared turnover has no total at all. It says what input is missing.

No double credit

Credit a forwarded slip by its bank reference. The same reference cannot be credited twice.

Exact payment amount

PromptPay, QRIS, Pix, VietQR, KHQR or your own banking-app code can sit beside the bill, with the amount embedded wherever the rail supports it.

A period that can close

Close the collection period only after the plan tells you what remains due; the ledger keeps the history and carries the balance forward.
