# Embedded payroll engine (Proliant ReadyPay)

> Proliant ReadyPay powers Encore's embedded payroll engine, handling gross-to-net, direct deposit funding, and federal and state payroll tax filing.

## Overview

**Proliant ReadyPay** powers Encore's embedded payroll engine. Proliant is the system of record for payroll: it calculates gross-to-net, funds direct deposits, files federal and state employment taxes, and produces W-2s, 1099s, and pay stubs. Encore drives the run end-to-end through the [ReadyPay payroll run wizard](/hr/proliant-payroll-run) and reads results back for reporting and GL handoff.

An earlier exploration evaluated a third-party embedded payroll engine. That direction has been superseded by Proliant ReadyPay and removed from product scope. The active payroll workspace lives at `/hr/payroll/runs`.

## What runs in Proliant vs. Encore

| Responsibility                                                      | Owner                                                                                     |
| ------------------------------------------------------------------- | ----------------------------------------------------------------------------------------- |
| Employee directory, time, PTO, deductions                           | Encore (pushed to Proliant)                                                               |
| Gross-to-net calculation, taxes, net pay                            | Proliant ReadyPay                                                                         |
| Direct deposit funding                                              | Proliant ReadyPay                                                                         |
| Federal and state employment tax filing (941, 940, W-2, W-3, state) | Proliant ReadyPay                                                                         |
| Pay stubs, year-end forms (W-2, 1099-NEC)                           | Proliant ReadyPay (read into Encore for self-service)                                     |
| Payroll run wizard (start, preprocess, verify, approve, submit)     | Encore drives, Proliant executes                                                          |
| GL journal entries from payroll                                     | Proliant emits JournalEntry → Encore Finance & Accounting posts via [FA-43](/fa/overview) |

## Who it's for

HR and Finance admins responsible for payroll operations. The wizard requires the same payroll permissions used elsewhere in the HR Payroll workspace.

## Get started

* Configure the integration: [Proliant HCM integration — admin guide](/hr/hr-44-admin-guide).
* Run payroll end-to-end: [Run payroll with ReadyPay](/hr/proliant-payroll-run).
* Day-to-day sync, run outcomes, and timesheet push: [Proliant HCM integration — user guide](https://github.com/Encore-OS/encoreos/blob/development/docs/hr/hr-44-user-guide.md).

The embedded run wizard (calendar → preprocess → verify → reconcile → approve → submit) and the JournalEntry → FA-43 handoff are live as of HR-44 Stage 2. Run history lives in [Payroll runs](/hr/payroll-runs); the [legacy Encore create-run wizard](/hr/create-payroll-run) remains for non-Proliant payroll flows.
