A perfect fit if this sounds like you
Built for operators who lease multiple spaces and still reconcile monthly billing and collections by hand.
- Building owners and property managers leasing multiple retail, office, storage or parking units
- Operators renting by the hour or day — meeting rooms, coworking spaces, study rooms
- Guesthouse and short-stay operators (bookings, guests and housekeeping included)
- Management offices that split maintenance fees and metered utilities in spreadsheets
Immediate wins, lasting value
Right away (first month)
- One click on [Create this month's invoices] bundles contracts and meter readings into invoices and emails them as PDFs.
- Draw your spaces in the floor-plan editor and see vacant and leased units at a glance.
- Pick your business type at setup (long-term lease, monthly rental, short stay, hourly rental) and the dashboard adapts to it.
Long term (after a year)
- Renewals, billing and settlement run on the same day every month, reducing arrears and omissions.
- Rental data accumulates on your own servers and becomes the basis for vacancy and revenue analysis.
- E-signature, e-tax-invoice and SMS adapters are already built in — moving to another region or country just means choosing an integration.

Skip building from scratch — buy something that already runs
Today, not months from now
The months of planning, design, development and stabilization are already done. Install it the day you receive it and start operating right away.
Real screens, not a quote
With commissioned work you pay before you see the result. Here you choose by looking at screens that run today and at the actual source layout.
No cost of a failed project
Many outsourced projects run over schedule and budget. With a finished product, we have already carried that risk — and finished the job.
The entire source is yours
This is not a subscription that stops the moment you cancel. You receive the full source and run it on your own servers under your own brand (resale and redistribution excluded).
Let us run it, or take the whole thing
The same solution comes in two forms. Choose the monthly plan if you would rather not manage servers, or the full source to run it your way on your own servers.
Monthly plan — a hosted instance we run
No server to prepare. We launch and operate an instance dedicated to your company, and you open it straight from your library.
- A dedicated instance — your data and accounts are never shared with other customers.
- We prepare and manage the server, database, Redis and SSL certificate.
- You receive the first admin account and the access address.
- We handle updates, security patches, backups and incident response.
- The fee is deducted from your points every month from the day the instance is delivered. If your balance runs short, it pauses after a 7-day grace period and resumes when you top up.
Source code is not included — buy the full source separately if you need it. For feature changes, use customization.
Full source — run it yourself on your servers
Pay once and receive the three items below. Installation and operation are up to you.
- Full source (GitHub repository zip)The whole repository, packed as is — git history included. Secrets (.env · keys) are not included.
- Database dumpThe table structure and the base data needed for a first launch (settings · menus, etc.). None of our customer or operating data is included.
- Installation guideStep by step: preparing the server → starting Docker → restoring the dump → the first admin account → scheduler setup.
We keep a copy, a SHA-256 hash and the delivery time of every file we hand over — so what you received can always be proven.
Here is what the source you receive looks like

Everything — database and Redis included — in one Docker setup

What we stand behind — and what we can't
We guarantee it — installed exactly as delivered, the features below work. If they don't, we fix them.
- Registration of spaces, tenants and contracts, with business-type dashboards
- Monthly invoice generation · line editing · PDF · email sending · payment marking
- Core flows for meter readings · utility allocation · bookings · guests · housekeeping
- Admin and staff permissions with audit logs
What we can't guarantee
- Anything arising from changes you make to the source yourself, or from repurposing it for a different use.
- Policy changes, outages or fees of external services (exchanges, payments, AI, SMS, email, etc.), and problems with the servers, network or database you provide.
- Business outcomes such as sales, profit or investment returns.
- Resale or redistribution — the source is licensed for the operation of a single customer.
If you need someone accountable for the modified parts too, leave the customization to us below.

Read the support guide →Why don't we open the demo to everyone?
Public demos attract AI agents and bots long before people — and in far greater numbers. With no intention to buy, they click through screens endlessly, trigger the demo's AI features and external integrations, and clutter the data other visitors are looking at.
Those costs (servers, AI calls, cleanup time) ultimately land on the prices and support we offer real customers. We decided to stop that unnecessary loss and keep our prices low as a result.
That is why we issue a separate demo to each person who asks. The account is yours alone, so it never mixes with data created by others, and you can test any scenario you like.
Request a demo account →We tailor it to the way you work
You are free to modify the source yourself — but if you are short on time or confidence, just send us your spec. The people who built it will make the changes.
- 1Send your specDescribe what you want changed, or upload a file. Any format is fine.
- 2Review · questionsWe read it and email you about anything that is unclear.
- 3Quote · scheduleWe send you the scope, price and timeline.
- 4Contract · developmentWe build exactly the agreed scope and show you progress along the way.
- 5Delivery · warrantyWe deliver the modified source and warrant the changed parts as well.
Finding a treasure should feel like a win
It isn't always this cheap. During an event, we want the person who discovers this solution to think, "This, at this price?" We want to invite our customers into that thrilling moment of discovering a rare gem.
This price is possible because we are delivering a copy of something already built. But delivery and installation support take a fixed amount of hands-on work, so we cap how many we can sell each month.
So while the price is low, we regret that we cannot offer it to everyone. Please decide while this month's quantity lasts.
