The verdict in three sentences
A law firm that manages files on paper loses 6 to 10 hours a week searching for documents and risks missed limitation deadlines that cost far more than any software. A legal SaaS at 50,000-110,000 FCFA/month starts fast but stays generic; a custom application (build 4,500,000-8,000,000 FCFA) matches your actual legal workflows and becomes a firm asset. The break-even sits around 3 to 4 years of intensive use.
Legal SaaS or custom app: the real math
SaaS is appealing at first: no upfront cost, continuous updates. But over time the monthly bill adds up and the firm remains a tenant of its own data. A custom app requires an initial investment, then settles into a maintenance cost.
| Criterion | Legal SaaS | Custom application |
|---|---|---|
| Upfront cost | 0 FCFA | 4,500,000 - 8,000,000 FCFA |
| Monthly cost | 50,000 - 110,000 FCFA | 60,000 - 120,000 FCFA (maintenance) |
| 3-year cost | 1,800,000 - 3,960,000 FCFA | 6,660,000 - 12,320,000 FCFA |
| 5-year cost | 3,000,000 - 6,600,000 FCFA | 8,100,000 - 15,200,000 FCFA |
| Fit to local legal practice | Low | Total |
| Data ownership | Vendor | Firm |
| Dedicated digital vault | Standard | Tailored |
What the app concretely saves
Beyond cost, it is time and risk that shift. Here are the areas where a legal case app really moves the numbers in 2026 (order of magnitude).
| Function | On paper | With the app |
|---|---|---|
| Finding a document | 15 - 40 min | under 30 seconds |
| Missed limitation deadlines | 1 to 3 per year | 0 (automatic alert) |
| Fee billing | 2 h / case | automated |
| Client payment | Cheque / cash | Bank transfer + mobile money |
| Document version tracking | None | Full history |
| Cost of a paralegal | 200,000 FCFA/month | redeployed to higher value |
Mini case study
Mr. Kamau runs a law firm in Nairobi with 3 paralegals. Each one costs 200,000 FCFA/month and loses about 8 hours a week searching for documents, roughly 32 h/month across three. On a 160-hour base that is 20 % of a paralegal's time wasted, about 120,000 FCFA/month of lost value each, roughly 360,000 FCFA/month for the team. An app at 6,000,000 FCFA, amortised on time saved plus avoiding a single missed limitation deadline (often millions in liability), pays back in 16 to 20 months.

What does a custom legal app really cost in 2026?
Budget a build of 4,500,000 to 8,000,000 FCFA depending on modules (vault, billing, alerts, client portal), then 60,000 to 120,000 FCFA/month maintenance. SaaS stays cheaper for the first two years.
Is the digital vault really secure for authenticated deeds?
Yes, with encryption, redundant backups and timestamped version history. Every change is traced, which a paper binder can never do.
How does the deadline alert work?
The app automatically computes statutory deadlines from the case-opening date and sends email and push reminders. In 2026 this brings missed deadlines from forgetfulness to zero.
Can clients pay online?
Yes: bank transfer for large fees and mobile money for routine amounts, with automatic receipts and reconciliation into the firm's accounts.
How long to deploy?
A working MVP (cases + vault + alerts) ships in 6 to 10 weeks; billing and client-portal modules follow in iterations.
