Payroll & Staffing
Pay contractors and temporary workers on schedule via ACH.

Professional Services
Distribute client funds and vendor payments compliantly via ACH.
Bookkeepers

Why FiSTWorks?
Other tools make you learn NACHA first. We built ACH software that teaches you as you go.
Guided Correctness
Routing numbers validated on entry. Field constraints enforced in real time. The drafter guides you toward valid files with real-time checks and clear error messages.
Learn As You Go
Every confusing field has a help link to our wiki right next to it. Understand what “Originating DFI” means or which SEC code to pick — without leaving the page.
No Cryptic Errors
SEC codes show human-readable names with descriptions. Validation errors explain what's wrong and how to fix it — not “Record 6: field 3 invalid.”
Build Once, Reuse Forever
Save recipients, clone drafts, create templates. Quick-add lets you pay 200 vendors in minutes. Stop re-keying the same data every pay cycle.
Built on Enterprise-Grade Security
FiSTWorks runs on Microsoft Azure, which maintains SOC 2 Type II, ISO 27001, and PCI DSS certifications. We add additional layers of protection on top.
Always Encrypted
SFTP credentials encrypted at rest — never visible after setup, even to us.
Passwordless Auth + MFA
No passwords to steal, phish, or leak. Sign in with a one-time code, and optionally enforce multi-factor authentication across your organization.
Data Masking
Account numbers masked at every layer — UI, database, and logs.
Audit Trail
Every action logged immutably — who did what, and when.
No Data Retention
ACH file contents are never stored beyond processing. Your data stays yours.
