Each has its own mode: logged a launch. handed out a wristband. sold a ticket. sold a product. Submitted the results.

RentOS works out how much should be in the register. The employee enters what actually turned up. You see the difference the same evening, for every zone and every employee.

The mode depends on how you take the money

Counters

Paid at the moment of launch

Electric car #2
Was 1,450
Now 1,478

28 × 100 = 2 800

Nothing extra to buy. If there is already a meter, we read it; if not, the employee taps to log the ride.
This is how vehicle rentals count: electric cars, karting, quad bikes.

Works on any device. An old tablet, an ordinary smartphone or the computer at the counter. Hardware makes the accounting stronger, but no mode requires it.

Modes can be mixed. A location can have any number of zones in different modes — they live in one dashboard and one cash register. How that looks where a register, a rental and a trampoline stand side by side is covered in the article on revenue control in a small amusement park.

Exactly the access that is needed

A PIN instead of an account

An employee needs no email. Once dismissed, the PIN is deactivated and access closes instantly.

Only their own zones

An employee sees and submits only what they are assigned to. Other zones and locations are simply not shown to them.

A device tied to the location

The device belongs to the point, not to a person. Another employee comes on duty and simply enters their PIN — nothing to set up.

Asset locking

On a given device you can leave only the needed assets available — the rest cannot be sold by accident.

Cancellations belong to the owner only

An employee cannot void a completed sale under any payment method.

Server time

Every operation records who performed it and when. The clock on the device has no say in it.

One ledger for everything

Rental, tickets, products, expenses, cash collections and float all write into a single money ledger. No need to reconcile several tills with a calculator at the end of the month. A single purchase can be split across several payment methods at once.

Cash on hand at the location

Always current and broken down by payment method — you see how much money is physically at the location right now.

Expenses and profit

Expenses are kept by category, with a register and a profit report — you see at once what is left after all the spending.

Cash collections and float

A couple of taps, with a record of who took the money and when. No more arguments about who handed over what.

Split payment

A single purchase can be split across several methods at once: part in cash, part cashless, part from the client balance.

Coffee, balloons and everything else sold alongside

Selling extras is separate money and a separate register. In RentOS they live their own life and do not get mixed into the results submission.

Catalogue and a sale in two taps

Products with categories and photos. Pay by cash, cashless or from the client balance.

Held orders

Open a table, add more with the same tap on the catalogue, settle up on the way out. Each order has its own number and its own name.

Soft stock levels and stocktaking

The system shows the calculated stock, and a stocktake brings it in line with reality without arguments or manual recounts.

Its own till reconciliation

The Products till is reconciled separately from rental — one does not drag the other along.

Regular guests come back

A wallet by phone number

One balance across all locations and all formats: sessions, time, tickets, products.

Abonements

Top-up plans: the client pays in advance at a better price, and you get predictable revenue.

Telegram instead of an app

The client checks their balance with one button, and you send out broadcasts. Installing yet another app is not needed.

No notebook and no we did explain it

Working time and payroll

Shifts, hourly rate, advances and bonuses with a check against the cash on hand, plus a rolling balance due.

Briefings with a signature

The employee reads and signs on screen: the text version, the time and a ready PDF are all stored.

Tasks

To do, In progress, Done. Assignment to an employee and a push notification. No deadlines and no fields nobody will fill in on the run.

You see everything without driving to the site

Four reports in the dashboard and two summaries that arrive on their own — Daily till and Shift close, in Telegram and by email. Connected with a one-time code, no tokens and no setup.

Calendar

What happened on each particular day.

Registers

How much each zone and each location brought in.

Employees

Revenue and Discrepancy broken down by people.

Trends

Revenue and profit trends over a period.

A landing page for social media and search

The company has a single public address — one page for the whole business, with all its locations and zones. It is built from your dashboard data: services, prices, addresses and opening hours, photos. Change a rate and the page updates itself, with no contractor and no “publish” step. It shows a live “open today” status based on the locations’ schedules, and visits are counted by our own statistics, without external trackers.

On the device you already have to hand

No special till, no POS terminal and no install from an app store. An old tablet, an ordinary smartphone or the computer behind the counter.

The app from a link

It goes onto the home screen from a QR code. A new device is connected with a single scan.

Survives a network outage

A results submission will not be lost: it is saved and sent once the connection is back.

The look is yours

The owner dashboard is light, the employee app is dark. The accent colour is configurable.

Questions and answers

Does RentOS suit me if I run several different formats on one site?

Yes, that is the standard case. Each zone is set to its own accounting mode: electric cars by counters, trampolines by launches, the play room by time, a quest by tickets. Reports, the money ledger and the results submission stay shared — you see the whole location, not four separate systems.

Do I need to buy special equipment?

No. Any tablet, smartphone or computer with a browser will do. The employee app goes onto the home screen from a QR code, without an app store.

What happens if the internet goes down at the location?

A results submission will not be lost: the data is saved on the device and sent once the connection is back.

How does the system help spot a shortfall?

At every results submission the system works out the calculated revenue from sessions, readings and tickets, while the employee enters what actually ended up in the till. The gap — the Discrepancy — is visible the same evening for a specific zone and a specific employee.
