A business cannot control its future while its core software depends on someone else's permission.
NowSquare builds and operates business software you install and keep, mostly self‑hosted, and works as an autonomous product‑development division for a few long‑term partners.

Hosted service · operated by NowSquare
Almost every loyalty platform, booking system and invoicing tool sold today is SaaS, and most self‑hosted alternatives are unmaintained. A supported product you install once and keep barely exists. NowSquare builds and operates the ones below; each title block states the model and where the source stands.
A white-label loyalty engine. Points, stamps, tiers, and coupons. One installation serves unlimited brands, for agencies that want to own their loyalty infrastructure.
Invoicing that runs on your server. PDF generation, payment QR codes, automated reminders. Your invoice data stays yours.
Appointments and reservations, open source and self-hosted. Booking pages for the salon, hotel, restaurant, or studio. You own the code and the data.
Describe your business and get a real website in Tailwind CSS 4 on your own server. Open source; bring your own AI key; the files are yours.
Digital stamp cards that work in any browser. Customers scan a QR code and collect stamps. No app download, no login friction.
Every self‑hosted product here is one PHP application and one database. That is the whole system.
| Product | PHP | Database |
|---|---|---|
| Reward Loyalty | 8.4.1+ | MySQL 5.7+ · MariaDB 10.3+ |
| InvoiceScript | 8.4+ | SQLite · MySQL · MariaDB |
| VoxelBooking | 8.3+ | MySQL 8.0+ |
| VoxelSite | 8.2+ | SQLite |
Figures come from each product's published requirements, checked 16 August 2026.
Software that needs a container cluster, a message queue and a platform engineer belongs to whoever runs that infrastructure. You paid for it, and you still cannot move it, read it, or keep it alive alone. We build the other kind: upload the files, point it at a database, and it runs.
That is the whole list. All four run on Apache or Nginx and need nothing else: no Docker, no Kubernetes, no Redis, no Node.js, no queue workers, no build step on your server. InvoiceScript's own installation notes put it plainly: Composer, npm, Vite, Node.js and command-line access are not required to install it. Shared hosting is enough.
There are millions of PHP developers. Any one of them can open this code and take over. That is what makes the licence worth something.
A subscription gives you access. Ownership gives you options.
Day one
The installation is yours.
The code ships with the licence. Any experienced developer can read it, extend it, or take over the installation.
Year one
It runs on your terms.
No licence server, no phone-home, no kill switch. You decide when to update and who touches the system.
Year three
It still runs if we don't.
Your customers stay in your database, on your infrastructure, with your backups and your GDPR responsibility. If NowSquare disappeared tomorrow, nothing stops working.
This applies to the self-hosted products. Stampify runs as a hosted service and its label says so.
Sem Kokhuis
Founder & Product Architect
Every NowSquare product and every partnership has one accountable product lead from strategy through delivery. These responsibilities never leave that desk:
AI speeds up the build. A person who has shipped products since 1999 decides what ships.
For a few companies at a time, NowSquare operates as the product‑development division they don't have to build: architecture, implementation, and roadmap input from one senior, accountable lead.
Senior involvement from day one, no account layers, and a six‑month minimum. The retainers are on the Partnership page.
More than twenty products across agencies, an owned internet venture, international contracting, and the current portfolio. One square per year. A filled square marks a year when a product first shipped.
Timeline from 1999 to 2026 in four eras: agencies and contracting 1999–2006, own SaaS platforms 2007–2015, NowSquare loyalty platforms 2016–2022, and the current portfolio from 2023. Years in which a product first shipped: 1999, 2007, 2010, 2012, 2013, 2014, 2015, 2016, 2018, 2023, 2024, 2025.
