Fortnox Reviews 

Vast and covers everything but a little too complex.

Very easy to operate and best for small scale entrepreneurs

Lots of great functionalities.

I was recommended to move over to Fortnox by a friend, and I don't regret it.

I find Fortnox very useful and powerful. It might not be exactly the GUI I prefer, but it is still very simple and easy to navigate, and the support is phenomenal.

I can recommend Fortnox as a very good solution.

I had a problem where entering data into my invoices was lagging significantly when using MS Edge (my preferred browser and the 2nd most common windows browser). This occurred after 12-14 months without a single issue using their software product. No other software did this except Fortnox. I use other web-based timesheet and invoicing software products without any trouble not to mention data entry in multiple other web-based software products without trouble - only Fortnox causes problems. The Fortnox problem occurred on 2 computers and no problems with any other sites or software on either computer - only Fortnox. This was taking me 3-4 times as long to complete an invoice as I could not see typing errors sometimes until 3-5 seconds after the keystroke. Then the delete key would not respond for a few seconds...and it was like that back and forth taking way longer than needed AND only affecting Fortnox on both a Dell and Lenovo PC.

I provided videos demonstrating this.

Fortnox customer support said that I should contact the browser developer (Microsoft). Really? The user needs to contact the developer, and not the developers of the Fortnox software? I have never experienced this from any other product support team ever and I beta tested hardware and software products for years.

You have a Fortnox software developer and a Microsoft operating system and browser. And you are telling the user, as the middleman, that they should contact one of the largest software developers on earth to troubleshoot your problem?

If something is wrong, you investigate it and sort out the issue - not tell the customer to do that.

Imagine having a problem with an app on your iPhone and contacting the developer and them telling you you need to contact Apple to sort it out.

1. Fortnox is a large company
2. Fortnox developed their product
3. There is a problem with their product and how it interacts with Edge, the #2 Windows browser (not some tiny fly-by-night weird browser)
4. This is not some extreme fringe use of their product, it is a basic fundamental problem - a user needs to be able to enter characters into a data entry field to create an invoice - it is not beta testing some extreme function, it is a basic need and if it is not functioning, for some reason, their attitude should be to explore why.

When a basic function is not working, you don't turn around and tell the customer to contact Microsoft. No excuses that they have not heard it from anyone else - I have videos of it occurring on 2 devices on 2 separate networks.

Fortnox has infinitely better resources than I do to contact Microsoft. I know because I have done IT support within the medical informatics field.

Either their IT team needs to sort it out, or they should contact Microsoft - BUT, they should not be telling the customer to contact Microsoft to solve their software glitch/bug. That’s a pretty bad look. I’m certainly glad you guys don’t provide site security and just do accounting software. That sort of IT attitude would never fly in many other IT support fields.

VERY Disappointing attitude to troubleshooting a problem. I see where all the other negative reviews are coming from.

Support still matters FortNox - wake up!

Just hard to understand the mix of Swedish and English as some parts of the app are in Swedish. It is so confusing that I had to hire an accountand to help me out with it. Even for the basic stuff, AI was not able to help me as good as an accountant, but added an extra expense on it.

The program is good, but horrible view on its customers. They charge for "modules" that have not been ordered, under the pretext "Everyone must have this". It's just plain worthless add-ons.

This is very much how today companies behave, they try lock in customers, and then charge more and more as long as it its possible.

It shows that Fortnox value of customers is zero.

Money money money, and more money... BAD BUSINESS, good platform on the other hand. Unfortunately they got greedy!

thank you for very good program, easy to understand and easy to use.

Your UI is really confusing, and at times your English translations are really, really bad. And not every function is supported in English.

AS a developer, fortnox handles every need as Accounting program used in Sweden. Good and clear documentation and their application met most of what our customer wanted to do through our integration.

System will not recognize me as an officer of my company

Well, the AI help can be much better, but overall good accounting application.

Doubled my monthly invoice by adding services I didn't ask for, I don't want. don't need and don't use and claim they are doing me a favour..

Easy to use and professional customer service, recommended.

Their business idea is to know ABSOLUTELY NOTHING about accounting. Those in support only answer about the structure of the program.

Read it again & realize the stupidity…

It often becomes a so-called “catch-22” in conversations with support.

Then inflexible when you end your subscription so if you do it 1 day late you have to pay 1 more year.

I would have liked to know this before my decision.

Good accounting program with many possibilities. Often to pay more and more… like so many other companies.

My accountant firm just told me that I now have to pay 1200:- per year for a Fortknox' service I never use. My book keeping is done annually, not monthly and for 10+ months per year I'll just pay for nothing.

My accountant firm is not happy either.

I will cancel my agreement with them after the shit that they made in the last week.
I have 2 Aktiebolag..so 2 less customers for them.
But it looks that is what they want.

See ya!

I had a great experience from start to finish. Everything worked smoothly and exactly as expected. The process was simple, fast, and reliable.

Excellent service and very reliable platform. Fortnox makes managing my business accounting simple and efficient. The interface is user-friendly and the support team is always helpful and responsive. Highly recommended for anyone running a business

The solution is clunky, not at all inituitive and seems more like something out of the 90s than a 2026 product.
The lack of automation, abscence of any kind of system intelligence and the out dated interface makes the whole accounting process painful.
In addition, the supports always (!) provide template answers without looking into the actual situation, which also maks it really hard to get the support you need without spending a lot of time.
The pricing model, with add ons for simple things like invoicing customers in other EU countries also makes the solution unreasonably expensive for small companies.
I am actively looking for a replacement.
