Per project
Best for one-off studies and consultancy mandates
A licence tied to a specific project and its timeline. Ideal when Tessa supports a defined study, tender or design phase.

Frequently asked questions
Can I try Tessa before buying a licence?
Yes. Create a free account to explore Tessa, then talk to us when you're ready for a licence.
What is the difference between fixed and floating seats?
Fixed seats belong to named users. Floating seats set how many people can use Tessa at the same time, and anyone in your team can take a free seat, so they suit larger teams with occasional users.
How does usage-based billing work?
Your organisation pays a base access fee, plus a variable fee for the storage and tools it actually uses. It suits organisations with many users or highly variable workloads.
Can I license Tessa for a single project?
Yes. Per-project licences cover a defined project and timeline, which suits consultancy mandates and one-off studies.
Are specialist modules included?
Yes. Every licence includes the full Tessa platform with specialist modules enabled by default. We can tailor the bundle if your market calls for it.
What if there is no data module for my region?
The OpenStreetMap module works wherever OpenStreetMap has building and street data, and our data integration service can bring your own GIS and building data into Tessa.
Can I combine a licence with training or consulting?
Yes. Training, IT and data integration, and design consulting can be added to any licence and are included in the same quote.
