Migrate custom CRM → code

Rebuild a legacy CRM as software your team can actually evolve.

We turn a home-grown or aging internal system into maintainable custom software — the workflows mapped (including the undocumented ones), your data migrated and reconciled, and your team's roles preserved — without pausing operations. You end up owning a product that can keep changing with the business.

What moves to code

  • The core workflows your team runs every day
  • A modern, documented data model
  • Role-based access your current system can't express
  • Reporting and dashboards designed in from the start
  • Brittle, hard-to-maintain integrations

What can stay as-is

  • The legacy system, read-only, while we phase in
  • Spreadsheets that still serve a real purpose
  • Anything not yet worth rebuilding

A phased split like this is the default for production teams — less cost, less cutover risk. A migration review draws the line for your case.

What we handle

The parts of a legacy rebuild that actually carry risk.

Workflow discovery

We map what the system actually does — including the undocumented rules living in people's heads — before we rebuild anything.

Users & roles

Fine-grained, record-level access is recreated so the modernization doesn't quietly change who can see or do what.

Data migration

Messy, multi-source data is cleaned, migrated and reconciled against source counts in a rehearsed run before cutover.

Reporting

The dashboards and reports your team relies on are designed into the rebuild, not bolted on afterward.

Every migration follows the same disciplined path — assess, scope, rebuild, validate, cut over, hand over. See how the process works.

Frequently asked

Legacy CRM rebuild questions.

Our system is undocumented — can you still migrate it?
Yes. Discovery is the first phase precisely for this: we work with your team to map the real workflows and the rules that only exist in people's heads, then rebuild against that shared picture.
Will we have downtime?
The legacy system stays available (read-only where needed) while we phase in the replacement, and we cut over in a controlled window with a rollback path.
How do you handle messy data?
We clean and reconcile it during a rehearsed migration, validating against source counts. Data quality problems are surfaced early, not discovered at launch.
Who owns the resulting code?
You do — the codebase, repository and infrastructure accounts, with documentation and full handover. There's no lock-in to us.
What does a legacy rebuild cost?
These scopes vary widely — run the estimator below for a recommended plan and timeline, then book a review and we'll confirm the scope and a fixed project price.
