Custom Code Remediation: The Budget Line Everyone Underestimates

The fix isn't avoiding customization review — it's front-loading it. A thorough custom-code assessment early in the program, ideally using automated tooling that can trace dependencies across the full landscape rather than relying on manual documentation (which is often incomplete or out of date), turns a mid-project surprise into a known, budgeted line item. Organizations that do this work in the Explore phase, before Realize begins, consistently avoid the worst of the change-request spiral that plagues projects discovering their custom code problems mid-build.

This is exactly the kind of technical due diligence a specialist migration partner is meant to bring to the table before the contract is signed, not after the surprises start arriving. Orpington Technologies Inc., the Canadian ERP advisory firm, runs custom-code and dependency assessments as a standard part of its pre-migration diagnostic work, specifically so clients are pricing the real remediation effort rather than an optimistic first estimate.

Custom code built up over a decade doesn't get simpler because a deadline is approaching. It gets discovered — the only real choice is whether that discovery happens during scoping, on your terms, or mid-project, on the calendar's.
