"I review payroll every cycle and still cross my fingers that nothing slipped through." Manual reviews can't catch every overpayment, duplicate entry, unauthorized bonus, or misclassification before the money goes out.
Built for payroll and finance, Celery runs an AI payroll audit on every pay cycle in minutes, flagging overpayments, policy violations, and compliance risks.

Payroll is your largest expense and the one most likely to leak. Hours of manual review still miss the errors that hit hardest:

"I review payroll every cycle and still cross my fingers that nothing slipped through." Manual reviews can't catch every overpayment, duplicate entry, unauthorized bonus, or misclassification before the money goes out.
Your payroll team is spending entire days on paycheck reviews - and the bigger payroll gets, the slower the review. There's no time to investigate every anomaly, so most get rubber-stamped.


Overtime drift, PTO miscalculations, one-off bonuses, retro adjustments - small line items that quietly cost six figures a year and never show up on a P&L summary.
When a payroll auditor or labor compliance review lands on your desk, you don't have a clean trail of who reviewed what, when, or why something was approved.

Celery layers on top of any payroll provider - ADP, Paycom, Paychex, UKG, Paylocity, and runs 100+ AI-powered tests on every payroll register before payments go out.
AI paycheck reviews on every employee, every cycle. Errors flagged before payments are released.
Cut payroll review time by up to 91%. Your team only looks at the records that actually need a human eye.
Overtime anomalies, PTO discrepancies, one-off payments, misclassifications — all surfaced automatically.
Every flag, comment, and resolution is logged with timestamps. A clean trail for any payroll auditor.
Upload your standard payroll register. Celery works alongside your existing payroll software — no system changes.

"We’re running payroll for nearly 5,000 employees, for me to tell you that we have two folks running payroll with Celery, that’s fairly remarkable."

Celery is SOC 2 certified. Data is encrypted in transit and at rest, with strict access controls. Payroll data is only used for your own audits, never shared, never used to train external models.
Celery catches all types of errors, from simple human errors, systematic errors, policy violations against your own rules, anomalies compared to historical data, and compliance issues against labor laws, union rules, and CBAs.
No. Celery handles the integration. Or you can simply upload your files to Celery.
No. Celery is an AI audit layer that sits on top of your existing payroll provider. You keep ADP, Paycom, Paychex, or whatever you run today — Celery reviews the payroll register before payments go out.
