What is Pay and Bill Software?
Pay and bill software combines worker payroll and client invoicing into a single system driven by a single timesheet dataset. While generic payroll tools only handle employee pay, staffing agencies must also bill clients at separate rates, apply markups, and track gross margins. Ascen automates this workflow by using a single approved timesheet to simultaneously trigger payroll and generate a white-label client invoice, eliminating duplicate data entry.
Onboarding
Eliminate manual paperwork bottlenecks. Ascen’s white-label platform allows your candidates to complete all pre-employment compliance tasks in one centralized location.
- Tax Withholdings: Automated setup for precise localized tax compliance.
- ID Verification: Secure, instant identity authentication built right into the workflow.
- Form I-9 and E-Verify: Fully digital eligibility verification to maintain total audit readiness.
- Credentialing: Simplified uploading and tracking for vital professional certifications.
- Custom Templates: Tailored document generation with embedded, legal e-signatures.

Timesheets and Expenses
Employees enter time and expenses through their white-label employee portal, with one-click and no-click approvals for end clients, so approved hours move into payroll without rekeying.
- White-label employee time and expense dashboard
- One-click and no-click client approvals
- White-label client portal
- Automatically calculate overtime and sync to payroll
Payroll Processing
Ascen doesn't stop at gross pay or force you to contract with a third-party payroll provider, as many middle-office solutions do.
- Gross pay calculated from approved timesheets and expenses
- Staffing-specific overtime rules
- Net pay and tax deposits handled in one platform
- White-label pay experience synced with client billing
Invoicing and AR Automation
Because Ascen's invoicing is built into the payroll platform, you bill end clients for time worked using the same records that run payroll, eliminating the gap between paying workers and billing clients.
- Transaction-level syncing from timesheets and payroll to invoices
- White-label invoices under your agency's brand
- Complex, automated invoicing grouping rules such as PO, Department, and Work Location
- Client reminders and backup data for audits
- Accounting integrations built in for QuickBooks, Xero, NetSuite, and Microsoft
