Is PayrollPenguin a drop-in CertifiedPayrollPro alternative?

PayrollPenguin covers the same federal WH-347 record and adds first-class support for the state electronic formats — NY MPWR, NJ Wage Hub + MW-562, CA eCPR, WA L&I PWIA — that contractors in those states need. You keep your existing payroll system.

Does PayrollPenguin guarantee my filings are compliant?

No. Like any certified-payroll tool, PayrollPenguin formats and flags — it does not guarantee compliance and is not legal advice. You certify each filing under your own name and the awarding agency reviews it.

CertifiedPayrollPro alternative

PayrollPenguin vs CertifiedPayrollPro — the certified payroll alternative for NY & NJ

CertifiedPayrollPro covers the federal WH-347. PayrollPenguin is built around the divergent state electronic formats — NY MPWR XML, NJ Wage Hub CSV + the MW-562, CA DIR eCPR XML, and WA L&I PWIA XML — generated deterministically from your existing payroll run, with anomalies flagged before you certify.

Where CertifiedPayrollPro under-serves

New Jersey Wage Hub + MW-562

New Jersey requires a specific Wage Hub CSV layout plus the MW-562 certified statement. This means a generic certified-payroll PDF does not satisfy the NJDOL Wage Hub upload. PayrollPenguin generates the Wage Hub CSV and the MW-562 from the same payroll data.

New York MPWR XML depth

New York’s NYSDOL MPWR system ingests structured XML validated against the official schema — not a PDF. PayrollPenguin validates every MPWR file against the NYSDOL Certified Payroll XSD before it’s presented as ready, so a schema-invalid filing fails loudly in the tool, not at the portal.

California eCPR and Washington PWIA full-SSN handling

California’s DIR eCPR (which rejects PDFs) and Washington’s L&I filing (RCW 39.12.120) both require the full SSN. PayrollPenguin never stores full SSNs by default — you supply the number at export, it’s validated against the stored last four, used in memory to build the file, logged, and discarded — and a missing SSN is flagged before you certify.

Generates NY MPWR XML, NJ Wage Hub CSV + MW-562, CA DIR eCPR XML, and WA L&I PWIA XML — not just the WH-347.

Deterministic: it reformats your own payroll data and never invents a wage.
Surfaces anomalies (missing fringe, classification gaps, rate below the determination) for review.
Keeps your existing payroll system — ADP, Gusto, QuickBooks, Paychex, or CSV.
