ACH (NACHA) Studio · Live

One studio for every step of an ACH file's life.

ACH (NACHA) Studio splits the workflow into three visual modules: generate a file, inspect a file, and triage the FedLine ACK response. Everything runs in the browser and keeps files local.

The ACH Flow · Visualized

Where each module sits in the file's journey.

A typical ACH file travels Originator → ODFI → FedACH → RDFI, and acknowledgment travels back. Studio's modules attach to the points where ops, engineering, and compliance need a microscope.

Three Modules · Three Jobs

Each module owns one part of the workflow.

Each module is a focused visual surface for the question your team is actually asking.

Module 01 Create

Generate NACHA

Sits at Originator → ODFI

Build a NACHA file from a visual form. Validate as you type and export text or PDF for downstream review.

  • Visual entry for header, batch, and entry records
  • Field-level validation aligned to fixed-width format
  • One-click text or PDF export
Open Generate NACHA →
Module 02 Inspect

NACHA Inspector

Sits at ODFI → FedACH gateway

Drop in any ACH file and inspect Header, Batch, Entry, Addenda, and Controls with validation details.

  • Tree-style structure views for record groups
  • Error/warning surfacing by line and field
  • Local parsing for faster incident triage
Open NACHA Inspector →
Module 03 Acknowledge

FedLine ACK Parser

Sits at FedACH → ODFI (return path)

Parse FedLine ACK payloads to understand accepted, pended, rejected, or duplicate outcomes quickly.

  • Status breakdown with clear operational meaning
  • Derived metadata and normalized identifiers
  • Reason-code extraction for faster response

Who uses it

Built for the three teams that touch ACH every day.

For operations

Faster file triage

Review structure, totals, and ACK outcomes before cutoff and resolve failures earlier in the day.

For engineering

Clear parser visibility

Inspect field-level parser output across NACHA and ACK data during integration and incident debugging.

For compliance

Local-first handling

Workflow stays in-browser so teams can reduce risk during QA, investigation, and evidence collection.

Open the studio. Run a file.

Everything runs locally in the browser. No signup, no upload, no waiting for an environment.
