Embedded Invoicing Software Built for Workforce Billing
The world’s only AI-powered Embedded Workforce Invoicer, built for EOR, PEO, staffing, and payroll billing, not adapted from generic AR software.

Trusted Workforce Operations Platform for EOR, PEO, Staffing, and Accountant Firms






Embedded invoicing built around workforce billing, not retrofitted for it
Most embedded billing software assumes a flat rate, one currency, and one set of rules per client. Workforce billing rarely works that way. A single pay period can span multiple clients, multiple jurisdictions, and multiple statutory burden rates, and every one of those variables has to reflect on the invoice correctly the first time.
Many EOR, PEO, staffing, and payroll companies have already built their own platform to deliver payroll and manage HR services, but never built the invoicing infrastructure to match. PHRBO’s Embedded Workforce Invoicer applies AI-driven rate matching and automation to that gap, so burden costs, worker hours, and multi-client billing rules calculate correctly inside the platform you already run.
One billing engine for salaried, fixed-rate, and timesheet-based workers
Not every worker bills the same way. Some are paid a fixed salary or flat rate; others log hours through a timesheet. PHRBO’s invoicing engine handles both within the same Pay Item structure, connecting directly to timesheet software to bring in approved hours where they apply.
- Supports salaried, fixed-rate, and timesheet-based billing models within the same Pay Item
- Connects with timesheet software to bring in approved regular, PTO, and overtime hours
- Embeds markups on timesheet-based worker expenses directly into the invoice line item
- Maps hours or fixed pay to the correct pay component and invoice rate without manual entry


Apply the right statutory rate, every jurisdiction, every time
Employer burden costs, including workplace injury compensation, health tax, pension contributions, and employment insurance, are matched automatically by jurisdiction, industry, and effective date. These rates factor directly into the Final Calculated Invoice Rate, so nothing gets missed at the point of billing.
- Jurisdiction- and industry-specific burden rate tables, versioned by effective date
- Automatic matching based on the worker’s registered region
- Optional inclusion of individual burden costs per Pay Item
- Historical calculations remain unaffected when rates are updated
- Sourced and matching your existing gross to net calculations
Run invoicing at platform scale, under your own brand
Invoices, payables, and payments generate together, in bulk, across every pay period and every client a platform serves. Delivered as white label invoicing software or embedded directly into an existing product, the underlying automation and burden logic stay the same either way.
- Multiple dedicated automation processes, to match your business processes
- Bulk generation across selected pay periods, not one invoice at a time
- Full invoice-to-payable-to-payment traceability for every line item
- White-label or embedded delivery behind a platform’s existing interface
- Multi-currency Invoicing with 4 decimal exchange rates

Check out common FAQs on PHRBO’s Workforce Invoicer
What is embedded invoicing software?
Embedded invoicing software lets a platform generate, send, and reconcile invoices directly inside its own product, using a white-label interface rather than routing clients to a separate billing tool.
How is this different from generic embedded billing software?
Generic embedded billing software doesn’t account for statutory burden costs or timesheet-based line items. PHRBO’s Embedded Workforce Invoicer applies burden rate matching and timesheet automation as core logic, not custom configuration.
Can PHRBO’s invoicing be white-labeled?
Yes. It can be deployed under a platform’s own brand or embedded directly behind an existing interface, with the same underlying automation and burden logic either way.
Does it support multiple clients and jurisdictions at once?
Yes. Invoices, payables, and payments generate in bulk across selected pay periods, with burden rates matched automatically by each worker’s jurisdiction and industry.
Can accounting firms use this for client billing?
Yes. Accounting firms can offer embedded AR/AP automation as part of their service, with direct export to QuickBooks IIF or Sage Intacct.
Does it require separate handling for payroll taxes?
No. A dedicated automation process handles payroll tax invoices, payables, and payments separately from standard payroll and fees, without added configuration per client.
