Custom law firm management software: delivered in 30 days for €105,000
A 50-person law firm replaced four tools with a custom ERP system delivered in 30 days for €105,000. IT SYSTEMES your law firm management software with no subscription fees, source code included.
A 50-person law firm managed its cases on Notion, handled billing through a dedicated tool, and tracked its staff in Excel. The result: daily data re-entry, inconsistent data, and reporting that was impossible to generate. Like many firms, it was looking for law firm management software that truly met its needs. A custom ERP system was delivered to them in 30 days for €105,000, compared to a competitor’s quote of €388,000.
What standard law firm management software doesn't cover
Law firm management software must address specific needs: tracking client cases, managing project phases, coordinating between partners and associates, time-based billing, and reporting by practice area. The SaaS solutions available on the market cover 80% of these needs. These are needs shared by most law firms.
The remaining 20% is how you work: your internal approval process, your method for evaluating a case, and your client follow-up process. These 20% are not covered by a standard tool. They never will be, because they are specific to your firm.
You've learned to work the way your software allows, not the way your job requires.
In practice, this results in Excel exports alongside the software, data having to be re-entered between tools, and data that doesn’t match up. And a question that keeps coming up in meetings: isn’t there a law firm management software that actually does what we need?
The Hidden Costs of SaaS Software for Law Firms
A SaaS provider builds its product with the majority of its customers in mind. As a result, you end up paying for features you don’t use. On average, 60 to 70% of the features in SaaS software are never activated. And the features you actually need are often missing or incomplete.
What the sales demo doesn't show:
• Per-user licenses: the cost increases with each new hire
• Additional modules billed separately from the basic subscription
• Integrations with your existing tools: complex, costly, and often incomplete
• Migration if you want to switch tools: €6,000 to €30,000, depending on the vendor
• Internal time lost on workarounds in Excel—unbilled but very real
Over a three-year period, the total cost of SaaS software for 20 users (licenses, integrations, modules, internal time) often exceeds €114,000. At the end of those three years, you own nothing. The code belongs to the vendor. If their prices go up or if they go out of business, you have no recourse.
A custom-built ERP system for a law firm, delivered in 30 days for €105,000
A law firm with 50 employees contacted us with this problem: its projects are structured in phases, involve multiple team members, and billing is tied to project progress. No off-the-shelf tool could centralize all of this. Generating reports was impossible.
The situation before
The firm was using four separate software programs: one for project management, one for tracking stakeholders, one for billing, and Excel to fill in the gaps. Every day, data had to be manually re-entered from one tool to another. The figures didn’t match up. It was impossible to monitor operations in real time.
A traditional vendor had provided a quote for custom law firm management software with a similar scope: €388,000, with an estimated delivery time of 12 to 18 months.

How IT SYSTEMES law firm management software in 30 days
30 days—that’s the first question. Does speed come at the expense of quality? No. Here’s how it works.
Hyperdevelopment: a method developed over two years of R&D
IT SYSTEMES standardized what is known as "hyper-development." The method is based on three elements that, when combined, reduce development time by a factor of 12 to 18 compared to traditional development.

The hyperdevelopment method
#
Step
What this means in practice
01
Assessment of Actual Needs
IT SYSTEMES what your teams actually use. The audit results in a use case document approved by your teams. What is approved is exactly what is built. Duration: 1 to 2 days.
02
Pre-tested technical bases
IT SYSTEMES on architectural frameworks that have been tested across dozens of CRM, ERP, and billing projects. The only part that is custom-built is the component specific to your firm.
03
AI-generated code, reviewed by an expert
The AI generates standard components in a matter of hours. A senior developer reviews, corrects, and validates the code before integration. The code is clean, well-documented, and can be maintained by any developer without specialized training.

Frequently Asked Questions About Law Firm Management Software
What is the best management software for a law firm?
There is no better all-in-one law firm management software. SaaS solutions meet the needs of 80% of law firms, but they cannot accommodate your firm’s specific business rules: your internal approval process, your client tracking methods, and the way you manage cases. Custom software developed using the hyperdevelopment method meets 100% of your needs, delivered in 30 days, with no monthly subscription fee.
How much does custom law firm management software cost?
Custom law firm management software starts at €30,000 for a CRM or multi-module case management system, and at €90,000 for a full-featured ERP. By comparison, a SaaS solution for 20 users over three years (licenses, integrations, modules, internal time) frequently exceeds €114,000—without ever giving you ownership of the code. A firm with 50 attorneys received a quote of €388,000 from a traditional provider for a scope of work thatIT SYSTEMES for €105,000.
Can a custom-built law firm software solution really be delivered in 30 days?
Yes, provided that an industrialized method is used.IT SYSTEMES rapid developmentIT SYSTEMES on architectural foundations tested across dozens of projects and on AI-generated code supervised by a senior developer. What used to take 4 to 9 months using traditional development methods now takes 15 to 20 days. The delivered code is clean, well-documented, and can be easily taken over by any qualified developer.
Who owns the source code for custom-developed management software?

How do I migrate data from my old law firm software?
Data migration is included in every plan at no extra cost. It includes an audit of your existing data, conversion to the new schema, validation in a test environment before going live, and a period of parallel operation if you wish. Issues are identified before go-live, not after.
Is custom software compatible with my existing IT system?
Yes.IT SYSTEMES architectureIT SYSTEMES designed to connect to any system that exposes an API: accounting ERP systems (Sage, Cegid), HR tools, Active Directory, Microsoft 365, and Google Workspace.

Phishing in 2025: Why 82% of businesses will be phished this year (and how to avoid being phished)
Think your employees will never click on a phishing scam because you've "trained" them? 32% will click anyway, and this figure rises to 45% under stress or at the end of the day. Attackers no longer make spelling mistakes, they have your logo, your graphic charter, and information about your actual projects. A single click = €275k in average costs, 287 days to recover if it's ransomware, and 60% of SMEs affected close down within 6 months. We explain why blaming users is absurd, and which technical protections really work.
