Built for Businesses That Pay via ACH

If you're making 10–200+ payments a month and tired of writing checks or fighting your bank's portal, FiSTWorks is for you.

Payroll & Staffing

Pay contractors and temporary workers on schedule via ACH.

Property Management

Distribute owner proceeds and pay vendors without writing checks.

Small Manufacturers

Pay suppliers on net terms with automated ACH batch processing.

Professional Services

Distribute client funds and vendor payments compliantly via ACH.

Bookkeepers

Import from QuickBooks, generate NACHA files, and transmit to the bank.

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.
