Common questions
What is a payroll spreadsheet analyzer?
A payroll spreadsheet analyzer is software that checks payroll data for errors. It verifies that net pay equals gross pay minus deductions, flags duplicate employee records, and confirms that tax withholdings match expected rates. It runs these checks across all rows automatically instead of requiring manual review.
How do I check if my payroll spreadsheet has errors?
Upload your payroll file to an analyzer. It will flag rows where net pay does not match the calculation, highlight duplicate employee IDs in the same pay period, and show which employees are missing expected deductions. It also totals each column so you can reconcile against your bank transfer amount.
Can it find duplicate employee payments?
Yes. The analyzer identifies any employee ID that appears more than once in the same pay period and shows both rows side by side. This catches cases where a correction was added without deleting the original entry, or where data from two sources was merged incorrectly.
Does it verify tax withholding amounts?
It flags withholdings that fall outside expected ranges for an employee's gross pay. It does not calculate the exact tax owed, but it will highlight a federal tax amount that is unusually high or low compared to similar employees, which indicates a formula error or outdated rate.
What does it cost?
You can try it free without an account, and the free plan includes credits every month. Paid plans add more credits and seats; every feature is on every plan. See the pricing page for current prices.
