Custom software development for businesses
Thirdlinks develops custom software for businesses in Norway. We build systems around the way you work, for when off-the-shelf software does not fit or you are juggling too many tools.

Many businesses use several programs that do not talk to each other, and fill the gaps with spreadsheets, email and sticky notes. That works for a while, but it costs time and causes mistakes as the business grows.
With custom software you get one system that does what your business needs. We build everything from a small internal tool to a larger line-of-business system with many users, roles and permissions.
We do not always recommend building something new. If an existing product covers your needs, we will tell you. Custom software pays off when the way you work is what sets you apart.
When does custom software make sense?
- Off-the-shelf software does not fit the way your business works.
- Information is scattered across spreadsheets, email and several systems.
- Your team enters the same data in more than one place.
- You pay for many tools that each solve only part of the problem.
- Key knowledge about your routines sits with just a few people.
What can we build for you?
Internal tools
Simple solutions that replace spreadsheets and manual routines, for example for orders, checklists or overviews.
Line-of-business systems
Larger systems with users, roles and permissions, built around the way your business works.
Customer portals
Solutions where your customers can log in, order, book or follow up on cases themselves.
Reports and overviews
Overviews that pull figures from your systems, so you can see where things stand without building reports by hand.
Hosting and further development
We can host and maintain the solution after delivery, and add new features as your needs change.
Who is custom software for?
- Businesses that have outgrown their spreadsheets
- Businesses with ways of working that off-the-shelf software does not cover
- Businesses that want to bring several tools together in one solution
- Businesses that want to give customers their own portal for orders or follow-up
- Founders and individuals who want to build a digital service of their own
How do we develop the software?
Step 1: We map how you work
We start with how you work today, who will use the system and what takes the most time.
Step 2: We prioritise what matters most
Together we decide what the first version must do. The rest can come later, once you see what works.
Step 3: We build in small steps
You see and test parts of the solution along the way, so we can adjust early rather than late.
Step 4: We deliver and keep improving
We test, put the solution into use and can keep improving it as new needs come up.

Questions about custom software
How much does custom software cost?
It depends on how large the system is and how many features it needs. After mapping your needs, you get a written quote with scope and price. Starting with a smaller first version is often a good idea.
Is it better to buy an off-the-shelf product?
Often, if an existing product covers your needs. Custom software pays off when ready-made solutions do not fit, or when you need to combine many tools to get the job done.
Can we start small?
Yes. We often recommend starting with what matters most and building on it once the first version is in use. That way you benefit from the system sooner.
Can the software connect to the systems we already use?
Often, yes. If your systems have an API, an interface for sending and fetching data, we can connect them. We check this when we map your needs.
Who owns the software?
Once paid in full, you get the agreed rights to use the solution. What is included is set out in the quote.
What happens after delivery?
We can host and maintain the solution under an ongoing agreement, and build new features when you need them. We fix documented defects in what we delivered at no extra cost.
Is there a way of working that should be simpler?
Tell us how you work today, and we will look at what software can solve.
