## Short answer

Vertex O Series is an indirect tax engine that keeps sales and use tax, VAT and industry-specific tax rules current for sales and purchase transactions. Infor documents the Vertex O Series configuration within CloudSuite. This page covers the general pattern; follow Infor's documentation for your exact CloudSuite product and release.

## Category

Sales tax and VAT

## Integration

**Method:** Configuration documented in Infor product documentation

**Detail:** Infor's CloudSuite documentation covers configuring Vertex O Series. The source page is for one CloudSuite release family, so check the guide for your product and version for field names and screens.

**Method:** Tax calculation call at transaction time

**Detail:** In this pattern the ERP sends a transaction (parties, addresses, items, amounts) to the tax engine, which returns tax amounts and jurisdictions. Tax is stored on the ERP document and reported through the ERP.

## Data Flows

**From:** Infor CloudSuite

**To:** Vertex O Series

**Data:** Customer or vendor, ship-from and ship-to addresses, item tax class, amounts

**Trigger:** Order, invoice or purchase document tax calculation

**From:** Vertex O Series

**To:** Infor CloudSuite

**Data:** Tax amounts, rates and jurisdictions

**Trigger:** Calculation response

**From:** Infor CloudSuite

**To:** Vertex O Series

**Data:** Posted transactions for tax records

**Trigger:** Invoice posting or period end

**From:** Infor CloudSuite

**To:** Vertex O Series

**Data:** Customer exemption certificate references

**Trigger:** Customer master change

## Setup

### Read Infor's Vertex guide

**Detail:** Follow the documentation page for your CloudSuite product and release.

### Obtain Vertex credentials

**Detail:** Get the connection details and company codes from Vertex and store them securely.

### Map tax classes

**Detail:** Map ERP item and customer tax categories to Vertex product and customer classes.

### Load exemptions

**Detail:** Bring in exemption certificates and tie them to customers and jurisdictions.

### Validate addresses

**Detail:** Make sure ship-to addresses are complete enough for jurisdiction determination.

### Test scenarios

**Detail:** Test domestic, interstate, exempt, use tax and VAT cases against expected results.

### Reconcile first period

**Detail:** Compare ERP tax totals to Vertex reports after the first close.

## Pitfalls

- Items with the wrong or missing tax class, so tax is calculated at the default rate.
- Incomplete ship-to addresses leading to wrong jurisdiction.
- Expired or missing exemption certificates.
- Tax recalculated on credit memos using different rates than the original invoice.
- Engine unavailable at transaction time with no clear fallback.
- Release upgrades changing tax field mappings.

## Ai Layer

### Tax variance explanation

**Description:** A private assistant compares ERP tax lines with Vertex results and explains the difference (class, address, exemption).

### Item class review

**Description:** Scan items for missing or inconsistent tax classes and draft corrections for a tax analyst to approve.

### Exemption gaps

**Description:** List customers shipping tax-free without a valid certificate on file.

### Plain-language audit questions

**Description:** Ask why a specific invoice was taxed at a given rate and get the inputs shown.

## Alternatives

- Infor's built-in tax tables if your footprint is a few states and rules are simple.
- Another tax engine if your corporate standard is different.
- Manual tax tables with periodic updates only for very low volume.

## Faq

### Where is the Vertex configuration documented?

**Answer:** Infor documents it in its CloudSuite product documentation. The page we reference is for one release family, so find the matching guide for your product and version on docs.infor.com before you plan configuration or testing.

### Does Vertex handle VAT as well as US sales tax?

**Answer:** Vertex describes O Series as covering sales and use tax, VAT and industry-specific rules. How much of that you use in Infor depends on your product, regions and the licensed Vertex modules.

### Can AI help reconcile tax without cloud exposure?

**Answer:** Yes. A model on your own servers can read ERP invoices and the tax engine's results to explain differences. It should not change tax settings; any correction goes to a tax analyst for approval.
