Guided Setup

Set Up Once, Use Forever

A step-by-step wizard walks you through company info, banks, and recipients. Routing numbers are validated as you type, and every field links to a wiki article explaining what it means.

  • Step-by-step setup wizard — no NACHA knowledge required
  • Routing numbers validated on entry
  • Help links on every field explain NACHA terminology
  • Save once, reuse across every file you create
Clear validation messages that explain how to fix issues
No Cryptic Errors

Validation That Speaks Your Language

Other tools show “Record 6: field 3 invalid.” FiSTWorks tells you exactly what's wrong and how to fix it — before the file ever reaches your bank.

  • Human-readable error messages, not NACHA spec references
  • Errors, warnings, and info categorized by severity
  • Fix issues in the drafter — the file is validated before generation
Preview and clone drafts for reuse
Build Once, Reuse

Templates, Cloning, and Quick-Add

Stop re-keying the same payment data every cycle. Save drafts as templates, clone previous files, or use quick-add to pay all your recipients in one click.

  • Save any draft as a reusable template
  • Clone from previous drafts with one click
  • Quick-add: select recipients, set amounts, done
  • Preview the raw NACHA file before generating
