## Short answer

Navigator iConnect Sales Tax Automation is a partner-built integration that connects Avalara AvaTax to SAP Business One, and also to SAP Business ByDesign, for real-time rate calculation and automated return filing. It is a partner tool, not an SAP-delivered feature, so support runs through Navigator and Avalara.

## Erp

## Erp Key

sap-b1

## On Prem

## Product

Navigator iConnect Sales Tax Automation

## Vendor

Navigator Business Solutions

## Category

Sales tax

## Integration

**Method:** Navigator iConnect integration tool

**Detail:** iConnect is Navigator's integration product. It sits between the ERP and Avalara, passes transaction data for calculation, and supports return filing automation as described on the vendor page. Business One users commonly run on-prem or hosted, so confirm the deployment and network path to Avalara with Navigator.

## Data Flows

**From:** Business One sales quote, order or invoice

**To:** iConnect then AvaTax

**Data:** Addresses, items, amounts, exemption

**Trigger:** Document is added or updated

**From:** AvaTax

**To:** Business One

**Data:** Calculated tax by line

**Trigger:** Response to calculation

**From:** Business One invoice

**To:** Avalara

**Data:** Committed transactions for reporting

**Trigger:** Posting, per iConnect configuration

**From:** Avalara

**To:** Business One

**Data:** Filing status and reconciliation data

**Trigger:** Scheduled or on demand

## Setup

### Confirm versions

**Detail:** Check Business One version, database (SQL Server or HANA) and add-on compatibility with iConnect.

### Set up Avalara

**Detail:** Create company, nexus, locations and tax codes in Avalara.

### Install iConnect

**Detail:** Deploy the iConnect service with Navigator, including service accounts and outbound access to Avalara.

### Map items and partners

**Detail:** Map item groups to Avalara tax codes and flag exempt business partners.

### Configure tax in Business One

**Detail:** Align tax codes and accounts so returned tax posts to the right ledger accounts.

### Test scenarios

**Detail:** Run sales, returns, freight and exempt scenarios against known results.

### Reconcile and file

**Detail:** Reconcile one period, then enable return filing once totals match.

## Pitfalls

- Business One tax codes that do not map one-to-one to returned jurisdictions, causing posting differences.
- Freight and handling taxed differently than expected by state.
- Upgrades to Business One breaking add-on compatibility until iConnect is updated.
- Credit memos not tied to the original transaction in Avalara.
- Firewall or proxy rules blocking the call to Avalara during peak order entry.

## Ai Layer

### Tax and ledger reconciliation

**Description:** A private assistant compares Business One tax postings to Avalara reports and lists mismatches with the probable cause.

### Invoice tax explanation

**Description:** Answer 'why was this taxed' by showing the document line, tax code and Avalara result, with the query visible.

### Filing readiness check

**Description:** Before filing, list unposted, uncommitted or adjusted documents for a person to review.

## Alternatives

- Business One native tax codes for a single-state business with simple rates.
- Avalara's own connector if one exists for your Business One version.
- Another tax engine such as Vertex through a different partner.

## Faq

### Is iConnect an SAP product?

**Answer:** No. The vendor page presents it as a Navigator Business Solutions integration. Support, upgrades and pricing come from Navigator and Avalara, so check them in your agreement.

### Does it file returns?

**Answer:** The vendor page describes automated return filing alongside real-time rates. Confirm which jurisdictions and filing frequencies are supported before relying on it.

### Can AI see Business One and Avalara data together?

**Answer:** A read-only assistant can query both on your own infrastructure and show the queries it ran. Changes to tax codes or documents should be drafted and approved by a person.
