Why TIVONIX
- 01
One owner of the result
The work is led by the TIVONIX founder: responsibility isn’t spread across contractors and decisions are made quickly.
- 02
Integrations as part of the architecture
Statuses, errors, retries and access are designed upfront rather than patched after launch.
- 03
Code and access stay with you
Source code, access, environment settings and instructions are handed to the client. The project isn’t locked to us.
- 04
Built in working parts
We show working parts of the system, not pictures: interface, server side, admin panel and integrations.

FAQ
Which payment systems have you integrated?
For example, bePaid in the Slotty marketplace. The provider is chosen for the country, currency and sales model.
Can subscriptions be added to an existing product?
Yes. We design plans, access and renewal flows and build them into the current system.
Can you add an integration to a product that's already live?
Yes. We review the current architecture and access first, then add the integration without breaking what already works.
How is the cost formed?
It depends on scope: how many roles, screens and scenarios, which integrations and launch requirements, and what already exists. Scope and price are fixed in writing after reviewing the task — before work starts.
How long does it take?
It depends on scope and on what already exists. We name the timeline after reviewing the task and split the work into stages with intermediate results, so you see progress instead of waiting for the end.
What do you need to get started?
A short description of the product and users, the task, and whatever exists already: designs, code, documents, access. That’s enough for a brief — we reply with the next step, risks, timeline and a cost range.
Which industries do you work with?
SaaS, fintech, e-commerce and internal systems. Launched projects include a booking marketplace, an AI commerce platform, a music fintech platform and a partner dashboard.
Who keeps the code and access?
You do. Source code, access and clear documentation are handed over to the client.
