Best EIS software for a Philippine manpower agency (when you don't run an ERP)
Most “e-invoicing software” is built for large taxpayers integrating SAP or Oracle. If you run a manpower or security agency, that is the wrong tool at the wrong price. Here is the buyer's checklist that actually matters for the EIS mandate — and how to tell agency-fit software from enterprise overkill.
Key Takeaways
- The best fit issues agency-to-principal invoices tied to deployed headcount, not generic e-invoices, and can be registered as a CAS.
- It should run on the same data as payroll and DTR — no re-keying, no second system to reconcile.
- You should not need an SAP/Oracle ERP. Requiring one signals the tool was built for a different buyer.
- Ignore “BIR-accredited” claims — no software is. Look for honest “EIS-ready” and “CAS-registrable.”
What should EIS software for an agency actually do?
It should output structured invoice data in the EIS format, support CAS registration, build each client invoice from deployed headcount, compute VAT and EWT (and, for security, the RA 11917 admin fee), and share one data spine with PH statutory payroll and DTR — all without requiring an enterprise ERP.
| Criterion | Agency-fit (what to want) | Enterprise e-invoicing (the mismatch) |
|---|---|---|
| Invoice model | Agency-to-principal, per deployed headcount | Generic product/service invoice |
| Registration | CAS-registrable; vendor supports the path | Assumes existing ERP/CAS |
| Payroll & DTR | Same data spine (no re-keying) | Separate systems, integration project |
| PH statutory depth | SSS/PhilHealth/Pag-IBIG, VAT/EWT, admin fee | Generic, PH rules bolted on |
| Prerequisite | None — no ERP required | SAP / Oracle ERP |
| Support | Local, knows the agency model | Global, generic |

Frequently asked questions
The best fit is software that issues EIS-ready agency-to-principal invoices tied to deployed headcount, can be registered with the BIR as a CAS, and runs on the same data as your payroll and DTR — without requiring an SAP or Oracle ERP. For a PH manpower or security agency, NexusWorkforce is built specifically for this model.
No. Enterprise e-invoicing tools assume a large-taxpayer ERP. An agency needs structured, CAS-registrable invoicing tied to headcount — a much smaller footprint. Requiring an ERP is a sign the tool was built for a different buyer.
Structured invoice output in the EIS format, CAS registration support, agency-to-principal billing tied to deployed headcount, correct VAT/EWT and (for security) the RA 11917 admin fee, integration with PH statutory payroll and DTR, and local support that understands the agency model.
No — it is a red flag. No software is “BIR-accredited”; the BIR registers a taxpayer's system. Look for honest “EIS-ready” and “CAS-registrable” claims and ask the vendor to show the registration path.
