## Short answer

SyteLine includes an External Payroll Interface form that imports payroll records and error results from Windows ADP payroll processing. It is a file-based hand-off, so the quality of the result depends on file format, timing and employee mapping rather than on a live API.

## Erp

Infor CloudSuite Industrial (SyteLine)

## Erp Key

syteline

## On Prem

true

## Product

ADP payroll (External Payroll Interface)

## Vendor

ADP

## Category

HR and payroll connector

## Integration

**Method:** File-based External Payroll Interface

**Detail:** The SyteLine HR module has an External Payroll Interface form documented in the product help. It reads payroll output files and error results produced by ADP payroll processing on Windows. Exact file layouts are in the SyteLine documentation, so follow that for your version.

**Method:** Scheduled file drop (common practice)

**Detail:** Most sites automate the file transfer with a scheduled job or shared folder so the import runs after each payroll cycle. This scheduling is community practice, not a vendor feature.

## Data Flows

**From:** SyteLine HR and labor

**To:** ADP payroll

**Data:** Employee hours and pay inputs prepared for payroll

**Trigger:** Payroll cycle close (verify the export path for your setup)

**From:** ADP payroll

**To:** SyteLine External Payroll Interface

**Data:** Payroll records after processing

**Trigger:** Payroll run completes and file is imported

**From:** ADP payroll

**To:** SyteLine External Payroll Interface

**Data:** Error results for rejected records

**Trigger:** Payroll processing produces an error file

## Setup

### Read the form help

**Detail:** Review the External Payroll Interface topic in the SyteLine HR help for your release and note the required file layout.

### Match employee identifiers

**Detail:** Make sure the employee number in SyteLine equals the identifier used in ADP, including leading zeros.

### Define the file location

**Detail:** Choose a secured folder reachable by both the ADP process and the SyteLine application server.

### Test with one pay group

**Detail:** Import a sample file in a test company and compare records to the ADP register.

### Handle error results

**Detail:** Decide who reviews the error file after every run and how corrections are made in SyteLine or ADP.

### Schedule and document

**Detail:** Automate the file movement, document the cut-off times and keep a runbook for payroll week.

## Pitfalls

- Employee numbers that differ in format between ADP and SyteLine cause silent mismatches or rejected rows.
- Importing the same file twice can duplicate payroll postings if there is no control on file names or run dates.
- Payroll file layouts change when ADP updates its output, and nobody notices until the import fails.
- Error results are easy to ignore, which leaves labor cost or accrual postings incomplete.
- Pay period and fiscal period boundaries differ, so costs can land in the wrong accounting period.
- The shared folder often has loose permissions, which is a problem for payroll data.

## Ai Layer

### Error file triage

**Description:** A private assistant reads the ADP error results alongside the employee master and explains each rejection in plain language, with a suggested fix for a person to apply.

### Payroll to labor reconciliation

**Description:** Compare imported payroll totals to SyteLine labor transactions by employee and week, and list the differences for review.

### Period boundary checks

**Description:** Flag imported records whose dates fall outside the open fiscal period before they are posted.

## Alternatives

- If you only need payroll totals in the general ledger, a summarized journal import may be simpler than record-level import.
- Keep payroll fully in ADP and post one monthly journal entry if labor costing by job is not needed.
- Use a different HR or payroll tool that has a certified connector to your ERP version if file handling is a burden.

## Faq

### Is this a live integration with ADP?

**Answer:** No. The SyteLine help describes a form that imports payroll records and error results from files produced by Windows ADP payroll processing. Timing depends on when the files are produced and imported.

### Does it work with SyteLine on-prem?

**Answer:** The External Payroll Interface is part of SyteLine's HR module documentation. File-based handling suits on-prem because both systems can read a controlled folder inside your network.

### What happens to rejected records?

**Answer:** ADP processing returns error results that the interface imports. Someone must review and correct them, otherwise payroll costs in SyteLine will be incomplete.

### Can AI see payroll data safely?

**Answer:** A model served on your own hardware can read the error file and employee master without data leaving your network. Restrict access by role and keep any write-back behind human approval.
