As your law firm grows and the demand for efficiency increases, it’s natural to ask:

“Should we build our own software… or is there something better already out there?”

At first glance, building custom legal tech might seem like the smartest way to meet your firm’s specific needs. But when you dig into the real costs, risks, and time involved, a legal software solution (like Prolegis) is likely to be a better fit for you and your team. 


The Temptation to Build


Many firms consider custom development when:

  • Current tools don’t “quite fit”

  • There’s a desire for more control over workflows

  • Tech-savvy leadership is eager to experiment


But legal teams quickly discover the hidden downsides of going custom:

Build Your Own

A Platform Like Prolegis

High up-front development costs

Affordable pay-per-matter pricing

6–12+ months before usable

Instant onboarding and access

Requires internal IT/project management

Fully supported by legal tech experts

Risk of scope creep or project abandonment

Continuously improved with legal workflows in mind

Maintenance and security are your responsibility

Built-in compliance, updates, and support


The True Cost of Going Custom


Custom projects often:

  • Exceed budgets 

  • Stall due to internal resource constraints

  • Require constant maintenance

  • Lag behind new legal or lender requirements


Many law firms, if not most, are not in the business of software development - and shouldn’t have to be.


The Case for Buying Prolegis


At Prolegis, we’ve worked closely with legal professionals across Canada to create a system that:


  • Fits real-world workflows for real estate law

  • Offers built-in automation, lender-specific outputs, and client-ready documents

  • Evolves with you - we release new features based on firm feedback every month

  • Doesn’t require a single line of code


Plus, Prolegis offers customizable templates, views, and workflows - so you get flexibility without the frustration of building from scratch.


Not Sure What’s Right for Your Firm?


Every firm is different. But here’s a rule of thumb:

If you’re looking to increase your efficiency, safeguard your practice, and maintain a firm standard; a platform built specifically for Canadian legal teams will almost always deliver faster results, greater consistency, and lower cost than a custom build.
