Gross-to-net runs, tax updates, and general ledger exports—payroll operations that finance trusts and employees understand on every payslip.

Payroll runs you can reconcile—journals, reversals, and audit trails built in

We build calculation engines and period workflows around your pay rules: multi-state taxes, contractor vs employee, garnishments, and retro adjustments. Outputs feed your accounting system with mapping you can defend in audit—not opaque CSV dumps. Employee self-service covers pay stubs, tax elections, and direct deposit; admins get exception queues when something does not balance.

Core calculations, time ingestion, and preview runs. Tax partner integration or update pipeline.

GL & compliance (weeks 10–18)

Journal exports, balance checks, and filing handoffs. Penetration testing on employee-facing surfaces.

Cutover (weeks 16–22)

Parallel payrolls until variances within tolerance; training for payroll admins; runbooks for year-end.

Operate (ongoing)

Monthly tax table updates; quarterly balancing rituals; annual form generation support.

05 // PRODUCT SCOPING

Choosing your path

Two engagement models—start lean and iterate, or commit to a full platform build from day one.

MVP

Speed & essentialism

Phase 1
MVP: salaried + hourly, single state cluster, core taxes via partner API, direct deposit file, GL export, employee stub portal. Excludes full international payroll, complex union logic, and built-in tax engine. Proves accuracy before decommissioning legacy payroll.
