A law firm has two pricing models to choose from. The SaaS model charges a subscription fee per user, typically between €40 and €150 per month per workstation, with no time limit. Custom-built solutions are billed as a one-time fee upon delivery: at IT SYSTEMES, starting at €30,000 for a CRM or case management system, and starting at €90,000 for a full ERP system, including source code.
Over three years, the gap narrows quickly. For 20 users, a SaaS solution (licenses, integrations, modules, internal time) often exceeds €114,000 without the firm owning a single line of code. The right decision depends on the firm’s size, the specific nature of its processes, and the payback period.
The Two Pricing Models, Plain and Simple
SaaS (Software as a Service): shared software rented on a subscription basis, billed per user per month. The law firm pays for the service, not the software. Examples in the legal market: Jarvis Legal, Secib, Kleos, Diapaz.
Custom software: a tool developed specifically for a firm, paid for in full upon delivery. The firm owns the code and has no recurring subscription fees to pay afterward.
Cost of SaaS Software for Lawyers
SaaS providers rarely disclose their public pricing, but the market generally ranges from €40 to €150 per month per user, depending on the modules activated. A firm never pays just for the license: it must also factor in optional modules (advanced billing, reporting, electronic signatures), integrations with existing tools, and the internal time spent on setup and training.
For a firm with 20 users, these cumulative costs over three years frequently exceed €114,000. And at the end of those three years, the firm has nothing to show for it: canceling the subscription means losing access to the tool and, in some cases, control over its own data.
SaaS covers about 80% of the industry's common needs at a low entry cost. The remaining 20%—your specific business rules—are never covered, and the expenses are endless.
Cost of Custom Management Software for Law Firms
At IT SYSTEMES, the schedule is public and consists of two lines:
| Scope | Starting price | Delivery Time |
|---|---|---|
| CRM or Multi-Module Case Management | starting at 30,000 € | 30 days or more |
| Full-featured ERP | starting at 90,000 € | 90 days or more |
This is a one-time payment. There is no subscription involved. Every package includes, without exception: a use case audit, data migration, a prototype validated prior to development, continuous testing, deployment, training, 30 days of support, the complete source code, technical documentation, and intellectual property rights. If the scope changes along the way, an amendment is signed before any additional development takes place. No charges are incurred without prior approval.
These prices are made possible by an industrialized development method—hyperdevelopment—which relies on architectural frameworks that have already been proven in dozens of projects and on AI-assisted code generation. This is what makes it possible to achieve a final price that is 5 to 7 times lower than that of an equivalent project developed using traditional methods.
A concrete reference point
A law firm with 50 attorneys received a quote of €388,000 from a traditional service provider for a specific scope of work. IT SYSTEMES delivered the same project for €105,000. The difference isn’t due to a reduced scope—it’s due to the methodology. To compare market players, see our comparison of custom software development providers for small and medium-sized businesses.
SaaS or custom-built: Which is less expensive over a 3-year period?
Here is a comparison over time, on a like-for-like basis, for a firm with 20 users.
| Criterion | SaaS (20 users) | Custom IT SYSTEMES |
|---|---|---|
| Entry cost | Basic (monthly subscription) | starting at 30,000 € |
| Total cost over 3 years | often > €114,000 | starting at 30,000 € |
| Code ownership | No | Yes, source code submitted |
| Meeting Business Needs | ~80 % | 100 % |
| Expense after 3 years | The subscription continues | Maintenance and custom upgrades, with no mandatory subscription |
| Start-up time | Immediate | 30 to 90 days |
If the firm wants a tool up and running by tomorrow morning and is willing to pay indefinitely, SaaS is the better choice. If it’s planning for three years or more, if it has processes that off-the-shelf solutions don’t cover, or if it refuses to depend on a vendor for its own data, a custom solution becomes the most cost-effective option.
The tipping point is around 18 to 24 months for a firm of this size. Beyond that, each additional month of the subscription widens the gap in favor of the custom solution.
What Really Affects the Price
Three factors shift the balance, one way or the other:
The number of users
With SaaS, the cost automatically increases with each user: doubling the number of employees doubles the subscription fee. With custom solutions, the number of users has almost no effect on the development cost. It is for large firms that the gap widens the fastest.
The Unique Nature of Your Processes
A firm whose organizational structure aligns with industry standards will find a SaaS solution to be a good fit. A firm with a unique internal approval process, its own client management method, or a specific way of managing cases will end up paying for features it doesn’t use in a SaaS solution, while having to improvise to make up for the ones it lacks. A custom solution charges only for what you need.
The pay-off period
The longer you keep the tool, the more cost-effective a custom solution becomes. Software that you pay for once and use for seven years ends up being much cheaper than a subscription paid for 84 consecutive months.

Frequently Asked Questions About the Cost of Law Firm Software
What is the minimum price for law firm management software?
With SaaS, the entry-level price is in the tens of euros per month per user. For custom solutions, development starts at €30,000 for a CRM or case management system at IT SYSTEMES—a one-time payment that includes the source code.
Is custom software always more expensive than SaaS?
No. The upfront cost of a custom solution is higher, but it ends with delivery. For a firm with 20 users, a SaaS solution often exceeds €114,000 over three years, whereas a custom solution starts at a one-time payment of €30,000. Over the long term, the custom solution becomes the more cost-effective option.
How much does an ERP system cost for a large law firm?
A comprehensive, custom-built ERP system starts at €90,000 at IT SYSTEMES, with delivery in as little as 90 days. As a point of reference, a law firm with 50 attorneys paid €105,000 for a project that had been quoted at €388,000 elsewhere.
Are there any hidden costs involved in custom development?
Not at IT SYSTEMES. The audit, data migration, prototype, testing, deployment, training, 30-day support, source code, and documentation are all included in the package. Any changes to the scope require a signed amendment prior to development.
Do we really become the owners of the software?
Yes. The complete source code and intellectual property rights are transferred to the firm. Unlike with SaaS, you are not dependent on any software vendor to continue using your tool or to access your data.
Prices and timelines provided by IT SYSTEMES are valid for a standard scope of work. The final quote depends on an audit of each firm’s specific needs.
