Works With Your
Existing Stack.

WhizFlow connects to your payroll software via file exports — not invasive API integrations. No changes to your existing setup. No new software for your clients to learn. Just drop files in SFTP, and WhizFlow handles the rest.

File-Based, By Design

We built WhizFlow around file exports — the format that every payroll platform already supports. This means no vendor lock-in, no API rate limits, and no fragile webhooks to maintain.

SFTP In

Files arrive via your existing SFTP server — no new infrastructure required.

Process

WhizFlow detects, classifies, and routes each file automatically.

Transform

GL mapping, format conversion, and validation applied per client.

Deliver

Output delivered via email, SFTP, or direct to accounting systems.

Supported Integrations

Production integrations are in active use at paying bureaus. “In Testing” integrations are in beta with select early-access partners.

Using a Different Platform?

If your payroll software produces file exports (PDF, CSV, Excel, fixed-width), WhizFlow can likely work with it. We configure filename patterns, column mappings, and delivery rules per bureau — no two setups are identical.
