Software that does exactly what your business needs.
CRM, ERP, accounting with Peppol, document management or a complete SaaS platform. Built by a full-stack expert, secure to the core, and entirely yours after delivery.
No agency prices. If someone offers exactly the same service cheaper, we go below it or honestly tell you why we can't. And we love to build in that little bit extra that saves you even more time.

MollieFrom internal tool to enterprise platform
No standard package you have to adapt to. We build the system around your way of working.
Accounting software with Peppol
Custom invoicing and accounting, with e-invoicing via a certified Peppol access point. Ready for the Belgian B2B obligation, without a monthly per-user licence.
Custom CRM
Customer management with exactly the fields, tools and flows you need: history, quotes, follow-up, tasks and reports. Nothing too much, nothing too little.
ERP and work management
Orders, planning, stock, production and invoicing in one system. Everyone works with the same, up-to-date figures.
Document management (DMS)
Contracts, quotes, inspections and certificates: automatically named, version control, approval flows and everything retrievable in seconds.
SaaS platforms
Your own online product with subscriptions, user management, payments and API. From MVP to scalable platform, we build the full stack.
Owner dashboards
One cockpit with your revenue, margins, outstanding invoices, team tasks and stock. Decide on real figures instead of gut feeling.
Employee dashboards
Every employee their own screen with daily tasks, instructions, documents and deadlines. Less walking around and calling, more getting done.
Customer portals
Let customers track orders themselves, download documents and submit requests. Fewer phone calls, a more professional image.
Enterprise integrations
Making existing systems work together: accounting package, online store, POS, email, warehouse. One truth instead of five separate islands.
Steer your team from one cockpit
Good software is an extension of your leadership. You see everything, your team knows exactly what needs to happen every morning.
- Assign daily tasks to employees, with all the info, documents and deadlines included
- Track progress live without having to chase anyone
- Rights per role: everyone sees only what's relevant to their job
- Automatic logs: who did what and when, always traceable
- Reports per employee, per project and per customer, without Excel fiddling
99% deliver a backend that fails sooner or later. Not us.
Cheap software works on day 1 and becomes a time bomb on day 400: slow, unmaintainable or worse, leaky. Leaked customer data means scammed customers, fines and a reputation you don't easily buy back. That's why we've been building back-ends that stay standing in the long term for 10+ years.
Strong password hashing, session security, MFA where needed and automatic lockouts against brute force.
Rate limiting, tokens, strict validation on every input. No SQL injection, no open doors.
Automatic encrypted backups with tested restore. A crash should never mean data loss.
Data minimisation, logging and retention periods correctly arranged. Your data stays yours, local if you want.
Clean code, documentation and migration paths. Another developer can also continue later, no lock-in.
We run businesses ourselves, with our own online store and business software. We build what works in practice, not what looks nice in a demo.

Frequently asked questions
What kind of software can you build?
From compact internal tools to enterprise systems: custom CRM and ERP, accounting software with Peppol e-invoicing, document management systems, SaaS platforms, customer portals and dashboards for business owners and employees.
Isn't custom work much more expensive than a subscription?
In the long run usually cheaper. Subscriptions per user per month keep running forever. Custom work you build once, after which it's yours, source code included. And we don't charge agency prices: lowest-price guarantee at equal service.
What about the security of our data?
With us security isn't an option but the foundation: hardened authentication, rate limiting, encrypted storage, automatic backups and GDPR-proof data processing. The last thing you want is leaked customer data.
Can you handle Peppol e-invoicing?
Yes. We build accounting and invoicing software that sends and receives via a certified Peppol access point, ready for the Belgian B2B e-invoicing obligation.
Why TST and not a big agency?
10+ years of IT experience, full-stack in-house and entrepreneurs ourselves: we run our own webshop and our own business system. You get software with a business mindset, without an agency margin on top.
