Legacy Pain Points

  • Heavy legacy desktop client dependencies and slow UI speeds
  • Complex upgrade processes that require certified integrators
  • Proprietary ICE middleware framework and ABAP-like workflows

The Custom Code Advantage

  • Sub-second React frontends built for shop-floor terminals
  • Modular TypeScript service architectures scaling dynamically
  • One-time development cost, avoiding yearly maintenance fees

Uncovering Hidden Constraints

What we don't do

Hidden Cost: Upgrade Consulting — stacked on the $30,000 - $200,000+ / year base license

What we do

Major version upgrades often require months of consulting and custom code rewrites.

What we don't do

Hidden Cost: Specialized Developers — stacked on the $30,000 - $200,000+ / year base license

What we do

Epicor ICE developers are scarce and charge premium hourly rates.
