Which licence do I need?

The Regular License covers one end product whose users use it free of charge, such as an internal tool or a client website. If your users pay to use the end product, for example a paid SaaS subscription, you need the Extended License.

Buying guide

Buy SaaS source code or build from scratch?

Building a business application from scratch means months of work on parts every system needs: sign-in, roles, multi-tenancy, billing, reports, an installer. Buying source code gives you those on day one, but only if the code is good enough to build on.

Side by side

	Buy source code	Build from scratch
Time to a working product	Days: install, brand and configure	Months of development before the first user
Upfront cost	A licence fee	Developer time for every module
Fit to your process	Good where the product already matches; you change the rest	Exact, because you design it
Ownership	You get and can modify the full source	Full ownership
Risk	Depends on code quality: check it first	Depends on your team, schedule and budget

What to check before you buy

A live demo you can click through in every role
Installation documentation and a clear list of requirements
A changelog that shows the product is maintained
Automated tests and a typed codebase you can extend safely
A licence that matches how you will sell or use it

When building is the better choice

If your process is unusual, the product is your core intellectual property, or you need deep integration with systems no product supports, a custom build can be worth it. DEV3 also builds custom software; see our services.
