## Short answer

Vergo captures, codes and routes supplier invoices for approval, then posts approved bills into Infor LN through the LN REST API, in the cloud or on-premise. LN keeps the ledger, payment run and vendor master, so Vergo handles the front end of accounts payable only.

## Erp

Infor LN

## Erp Key

infor-ln

## On Prem

## Product

Vergo AP Automation

## Vendor

Vergo

## Category

AP automation / invoice capture

## Integration

**Method:** Infor LN REST API

**Detail:** Vergo's documentation says approved bills are posted into LN over its REST API, for both cloud and on-premise LN. You will need API access, a service account with correct permissions and a network path from Vergo to your LN.

**Method:** LN as system of record

**Detail:** Vendor master, general ledger and payment runs stay in LN. Vergo reads reference data such as vendors and accounts and writes approved invoices, so master data changes in LN must stay in step.

## Data Flows

**From:** LN vendor and account master

**To:** Vergo

**Data:** Vendors, tax codes, ledger accounts, dimensions

**Trigger:** Scheduled sync

**From:** Supplier invoice (PDF, email, portal)

**To:** Vergo

**Data:** Captured header and line data for coding

**Trigger:** Invoice arrives

**From:** Vergo

**To:** LN

**Data:** Approved invoice posted as a bill

**Trigger:** Final approval complete

**From:** LN

**To:** Vergo

**Data:** Payment status

**Trigger:** Payment run, if exposed in the integration

## Setup

### Agree the scope with finance

**Detail:** Decide whether the flow covers non-PO invoices, PO matching or both, and who owns each approval step.

### Prepare LN access

**Detail:** Provision the API user with only the rights needed to read master data and post bills, and expose the LN REST endpoint securely if on-prem.

### Sync vendors and accounts

**Detail:** Clean duplicate vendors and inactive accounts in LN first, then sync them so coding choices are valid.

### Build approval rules

**Detail:** Configure routing by amount, department or cost centre, with delegation for absences.

### Test posting

**Detail:** Post sample invoices including credit notes, foreign currency and tax variations into a test LN company.

### Go live in waves

**Detail:** Start with a few vendors, review rejections, then widen coverage.

## Pitfalls

- Duplicate vendor records in LN causing invoices to post to the wrong supplier.
- Tax codes in Vergo not matching LN's tax setup, creating posting errors or wrong VAT.
- Duplicate invoices posted twice because the same document arrived by email and by portal.
- Foreign currency and rounding differences between captured totals and LN's calculation.
- Coding dimensions that exist in LN but are not synced, so invoices are coded to stale accounts.
- API credentials expiring or rotated without updating the integration.

## Ai Layer

### Exception explanation

**Description:** When a bill fails to post, read the LN response and the invoice and explain the cause in plain language, then suggest a fix for an AP clerk to approve.

### Duplicate and anomaly checks

**Description:** Compare incoming invoices to LN history and flag likely duplicates or unusual amounts before approval.

### Spend questions

**Description:** Ask what a supplier billed this quarter against receipts and orders in LN, with the query shown.

## Alternatives

- If invoices are few and mostly PO-based, LN's own invoice entry and matching may be enough.
- Other AP automation products with an LN connector may offer different matching and OCR strengths, so compare.
- Suppliers sending e-invoices or EDI invoices can bypass capture altogether for those vendors.

## Faq

### How does Vergo post invoices to Infor LN?

**Answer:** Vergo states that it integrates with LN through the LN REST API and supports both cloud and on-premise deployments. Approved bills are posted into LN, while LN continues to hold the ledger, vendor master and payment run.

### Does it handle purchase order matching?

**Answer:** The source describes capture, coding, approval routing and posting. Whether three-way matching against LN receipts is available for your setup should be confirmed with Vergo, since it depends on the configuration and the LN data exposed.

### Can AI be added without moving invoice data out?

**Answer:** Yes. A private assistant running on your own servers can read LN and invoice data to explain posting errors and flag duplicates, keeping data in your network, with every correction approved by a person before it posts.
