Market accounting
A deposit per shop: rent, security and electricity on one account
About the project
Market accounting is a system for the administration of markets and trade centres. Every shop has a single deposit account: the tenant tops it up through Payme, Click, cash or a terminal, and the system charges rent (by floor area, per m²) and security once a month, and the electricity actually used continuously. The meter reading is never written down by hand — the meter device sends the kWh itself, and the system multiplies it by the tariff and takes it from the deposit. When the deposit runs out the power switches off by itself, and comes back once the account is topped up. Every tiyin goes into a journal that cannot be erased: who, when, how much — so the argument about who already paid disappears on its own.

What changes
Meter readings
- With a paper book
- A member of staff walks round every meter and copies the numbers, and they come out wrong.
- In the system
- The device sends the reading itself and the usage leaves the deposit straight away.
Debtors
- With a paper book
- Who owes what is kept in someone's head.
- In the system
- The list builds itself and exports to Excel.
Payment
- With a paper book
- Cash with no receipt, and then a dispute over who already paid.
- In the system
- Payme, Click, cash — all in the journal, with whoever took it.
Cutting the power
- With a paper book
- Someone has to walk to the shop and switch it off by hand.
- In the system
- Below the set threshold it goes off by itself and comes back after payment.
Talking to tenants
- With a paper book
- They ask every day how much they owe.
- In the system
- They see it in the bot themselves, and a warning arrives when the deposit gets low.
