How it improves reporting
Payroll is one of the largest line items in any growth-stage company. Justworks sync drives accurate payroll by function (S&M, R&D, G&A), burn, runway, and P&L allocation in Lucius.
Common workflows
Sync pay runs to the ledger
Justworks pay runs post journal entries split by function and account (e.g. S&M salaries, R&D payroll taxes).
Reconcile payroll against bank settlement
Payroll debits from Mercury or Brex are matched to the originating Justworks pay run automatically.
Allocate payroll by function
Employee department mapping drives function-based COA categorisation for payroll lines.
