One Database, Many Real Estate Websites: How a Multi-Site Property Platform Works
How one listing database can run several real estate websites, each with its own brand, featured listings and translated SEO, with 2FA and a full change log.
Past a certain size, most companies run on spreadsheets, group chats and one person who remembers everything. We replace that with software built around how your operation actually works, and that replaces the spreadsheets for good.

Service 03 · Custom software
Unlockd builds custom business software for mid-sized companies and enterprise teams: operations platforms, CRM, booking systems, dashboards, client portals and automation. Each release is scoped and priced fixed, built in Next.js and PostgreSQL by the founder, and handed over with full ownership of the code and data.
Catalogue, quotes, orders, production, stock and shipping in one system with one source of truth. The alternative to an ERP you'd have to bend your business around.
Real availability, automatic staff assignment, confirmations, reminders and payments. Takes bookings while you're closed.
Built around how your sales actually happen, not around what a SaaS product assumed they would.
The numbers that decide things, always current, and a queue of what needs doing next. No exporting to Excel first.
Repetitive work removed: notifications, documents, reminders, invoices and handoffs between steps.
Email, WhatsApp, payments, postal and courier, calendar and accounting APIs wired in, so nothing gets typed twice.
A place for your customers to check status, documents and orders, without anyone answering the same question again.
QR and NFC tracking that follows each piece or order through the workshop, logged with a tap instead of a paper sheet.
Everything in the agreed scope, ready to use and yours to keep: the finished website or software with its source code, accounts and documentation, all images, and, when branding is part of the project, the final logo, visual identity, collateral and brand guidelines.
We follow the real workflow, including the parts that live in someone's head. Nothing is designed yet.
The smallest system that removes the biggest pain, priced fixed, so value arrives early.
Built and put in front of the people who'll use it every day, then corrected against reality.
Full rollout, training and the complete handover package, with post-launch support always included. New modules follow as the operation grows into it.
| Timeline | 3 to 4 weeks to a first working release |
|---|---|
| Price | From €6,900 for a first release, fixed per release, never hourly |
| Stack | Next.js, React, Prisma, PostgreSQL |
| Who builds it | The founder, end to end |
| Ownership | Your code, your database, your accounts. No licence fees |
| After launch | Post-launch support always included, plus an optional monthly plan for changes |
Buy it when an existing product genuinely fits, and we'll tell you when it does. Custom pays off when your workflow is specific enough that you'd bend the operation around the tool, when per-user pricing keeps growing with the team, or when the data you need is split across products that don't talk to each other.
A first release starts from €6,900. Each release is scoped and quoted as a fixed price, never hourly, so there's no incentive for the work to take longer. The first release is deliberately the smallest system that removes the biggest problem, which keeps the first number down and gets value in front of you early.
For most small and mid-sized operations, yes. A custom platform can bring catalogue, orders, production, stock and shipping into one system that fits how you already work, without the licence cost and configuration of a full ERP.
Yes. Your code, your database and your hosting accounts are handed over on completion. There's no lock-in and no licence fee, and another developer can pick it up because the stack is standard and the work is documented.
A first working release usually takes 3 to 4 weeks. We then extend it module by module, each with its own scope and fixed price.
Small changes and fixes are covered by an optional monthly plan. Anything larger is scoped as its own release with its own fixed price. Because the person who built it is the person who changes it, no time is lost relearning the system.
