The verdict in three sentences
For an 18-lawyer business firm in Miami, off-the-shelf platforms such as Clio, MyCase or PracticePanther cost roughly $50 to $150 per user per month, about $10,800 to $32,400 a year. A custom case management system built by a US agency typically costs $45,000 to $110,000 (2026 ballpark), delivered in 4 to 6 months. Custom makes sense when conflict checks, document management and hourly billing must fit the firm's own structure and recover the 10 to 15% of billable hours that currently go unrecorded.
The three pain points of a business law firm
An 18-lawyer firm handling corporate, commercial litigation and cross-border work with Latin America opens 250 to 400 matters a year. Three issues drain time and revenue.
Document management first: files sit across email, shared drives and data rooms, and an associate loses 20 to 40 minutes a day looking for the right version. Time capture next: hours are reconstructed on Friday from memory and some never reach an invoice. Conflict checks last: run manually in a spreadsheet, they expose the firm under Florida Bar Rule 4-1.7 and 4-1.9.
| Function | What the software does | Expected impact (2026 estimate) |
|---|---|---|
| Matter intake | Client record, adverse parties, beneficial owners, KYC | Intake in 10 minutes instead of 45 |
| Conflict check | Search across all parties and related entities, 10 years of history | Systematic, logged check |
| Document management | Versions, matter indexing, full-text search, Outlook add-in | 20 to 40 minutes saved per person per day |
| Time capture | Timer, entry from Outlook and mobile, UTBMS codes | 10 to 15% billable hours recovered |
| Billing and trust | Flat fees, hourly rates, retainers, IOLTA trust ledger | Billing cycle shortened by 15 to 25 days |
| Dashboard | WIP, realization rate, profitability per partner | Reliable monthly management |
Clio or custom: the comparison
Clio and its peers cover the core well: calendar, matters, billing, trust accounting. Limits appear with business-firm conflict rules (corporate groups, funds, holdings), integration with an existing DMS such as iManage or NetDocuments, and partner-level reporting.
| Criterion | Off-the-shelf (Clio and peers) | Custom (US agency) |
|---|---|---|
| Upfront cost | $2,000 to $10,000 setup and migration | $45,000 to $110,000 |
| Recurring cost (18 users) | $10,800 to $32,400 a year | Maintenance and hosting, 10 to 15% of build per year |
| Time to go live | 4 to 10 weeks | 4 to 6 months |
| Conflict rules | Name search, limited settings | Graph of related entities, firm-specific rules |
| Document management | Built-in module or connector | Connect existing DMS or dedicated one |
| Data ownership | Vendor hosting, export available | Hosting chosen by the firm |
| 5-year cost (median scenario) | About $110,000 | About $105,000 to $120,000 |
Median scenario: $110 per user per month off the shelf (18 × 110 × 12 = $23,760 a year, about $119,000 over 5 years, about $110,000 with multi-year discounts) against a $70,000 build and $8,500 a year of maintenance. At similar cost, process fit becomes the deciding factor.
Security and client confidentiality
There is no HIPAA-style hosting requirement for a law firm, but ABA Model Rule 1.6(c) requires reasonable efforts to protect client information: encryption at rest and in transit, two-factor authentication, access logs, US hosting, daily off-site backups. Florida's data breach statute (FIPA) adds 30-day notification duties.
| Requirement | Technical measure | Indicative cost (2026 ballpark) |
|---|---|---|
| Confidentiality | AES-256 encryption, TLS 1.3 | Included in build |
| Access control | 2FA, ethical walls per matter | $3,500 to $9,000 |
| Traceability | Per-document access log | $2,500 to $6,000 |
| Hosting | US cloud region, SOC 2 provider | $250 to $900 a month |
| Backup | Daily, 30-day retention, restore tests | $60 to $250 a month |

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Maria, managing partner of an 18-lawyer firm in Miami, sees her timekeepers bill on average 1,500 hours a year at a blended $420 rate. Part of the time is never captured.
If Outlook-based entry and a timer recover only 10% more hours for 12 billing lawyers: 12 × 150 hours = 1,800 hours. With a cautious 70% realization rate, the gain reaches 1,800 × 420 × 0.70 = $529,200 a year.
Even at half that assumption, a $70,000 build pays back in under 4 months. That calculation, more than licence prices, should drive the decision.
FAQ
Can we keep our current DMS?
Yes. A connector to iManage, NetDocuments or SharePoint typically costs $7,000 to $18,000 within a custom project. Documents stay where they are and are linked to matters.
How does the conflict check work?
At intake the system searches the client, adverse parties and related entities across 10 years of history. The result is timestamped and archived, documenting the check if the Bar ever asks.
Can we migrate from Clio?
Yes, through its API and exports. Allow 2 to 4 weeks for 3,000 to 5,000 matters, including contact deduplication.
Will lawyers really log their time?
Adoption depends on friction: three clicks from Outlook or mobile. Firms that do it typically see 10 to 15% more hours captured within the first quarter.
How fast can a first module go live?
A core of matters, conflicts and time capture can be in production in 10 to 12 weeks, with billing and DMS following within 2 to 3 months.
