Which one, for what
Everee C
Good for A staffing, delivery or vertical software platform, or a single employer, that pushes hours and flat payments for W-2 and 1099 workers and lets admins approve in Everee's portal.
Ahead on
- Reliability, 87 against 58
Also in its favour
- A hosted endpoint, with nothing to install
Watch for
No preview or approval endpoint was found. Payments are approved by a payroll admin in the Everee portal, or automatically if Everee sets that up.
Gusto B
Good for A software platform that wants to run US payroll for its own customers and can pass Gusto's partner reviews.
Ahead on
- Schema & documentation, 86 against 67
- Agent ergonomics, 82 against 56
- Security & auth, 60 against 43
- Payments & pricing, 15 against 10
- Maintenance & community, 76 against 46
- Transparency & trust, 61 against 56
Watch for
Production keys need commercial, security and implementation reviews with Gusto's partnerships team, and the docs say not all use cases are supported

Verdicts
Everee
Everee's API tokens are created in the admin portal of each company instance, and payments wait for a payroll admin's approval unless auto-approval is arranged. The API has no preview or approval endpoint, no single OpenAPI file, no SDK and no changelog, and a company instance starts with a sales call.
Gusto
This listing covers the Embedded Payroll API. Every reference page carries an OpenAPI 3.1 definition, payroll is calculated as a preview before submission, and each API version gets 12 months of deprecation support. Production needs commercial and security approval, no price was readable, and the status page lists 11 incidents between 14 July and 5 October 2026, five marked major.
Before you call either
Everee
- Send two headers on every call,
authorization: basic <token>andx-everee-tenant-id. Base64-encode a token that starts withsk_first. - Derive each payable's
externalIdfrom stable data, never a timestamp or UUID, so a retried create is rejected instead of paying twice. - For contractors, call POST
/integration/v1/payables/payment-requestafter all payable items are sent and before admins approve. Without it contractors aren't paid. - Send hourly wages through the Timesheets API, not Payables, and assign
workLocationIdso tax is worked out for the right jurisdiction. - Don't expect the API to move money alone. Tell the user a payroll admin must approve in the portal unless auto-approval is enabled, and read Everee's terms on automated access first.
Gusto
- Develop against https://api.gusto-demo.com. Production at https://api.gusto.com needs keys Gusto issues after its reviews
- Send
X-Gusto-API-Version: 2026-06-15on every call. Without it the application's minimum version applies - Send the resource's current
versionwith every PUT, and only the fields to change. A stale version returns 409 - Calculate and submit return 202. Poll GET on the payroll until
calculated_atis set or the status is processed, and readsubmission_blockersfirst - For a company already on Gusto, the Embedded API is the wrong route. Use the Gusto CLI or the MCP server at https://mcp.api.gusto.com, which draft payroll but can't submit it
