# Avalara AvaTax with Infor LN and Other Infor ERPs > Source: https://netray.co/stack/avalara-avatax-infor-ln > Publisher: Netray (netray.co), AI and integration engineering for ERP and manufacturing systems. > Section: ERP Stack ## Short answer Avalara AvaTax calculates sales tax in real time on invoice lines, manages exemption certificates and supports returns filing. Avalara announced connectors for Infor products in 2016, covering CloudSuite Industrial, VISUAL, XA and LX, with LN, M3 and SX.e also named. Current support for LN is unverified, so confirm it with Avalara before you plan around it. ## Erp Infor LN ## Erp Key infor-ln ## On Prem true ## Product Avalara AvaTax for Infor ## Vendor Avalara ## Category Sales tax ## Integration **Method:** Avalara connector for Infor **Detail:** The 2016 announcement describes Avalara connectors for several Infor ERPs, with LN, M3 and SX.e mentioned. The announcement is the only source in this record, so current availability, version coverage and who maintains the connector should be confirmed directly. **Method:** AvaTax REST API (general pattern) **Detail:** If no maintained connector exists for your LN version, the usual alternative is custom integration to the AvaTax API from the sales and invoicing flow. That is a custom project, not a vendor-certified recipe, and it carries ongoing maintenance. ## Data Flows **From:** Infor LN **To:** Avalara **Data:** Ship-from, ship-to, item tax code, line amounts, customer and exemption data **Trigger:** Order or invoice calculation **From:** Avalara **To:** Infor LN **Data:** Tax amounts and jurisdiction breakdown per line **Trigger:** Response to the calculation request **From:** Infor LN **To:** Avalara **Data:** Committed invoice transactions for reporting and filing **Trigger:** Invoice posted **From:** Avalara **To:** Infor LN **Data:** Exemption certificate status for customers **Trigger:** Certificate uploaded or expired ## Setup ### Verify support first **Detail:** Ask Avalara whether a maintained connector exists for your exact LN version, and what it covers: order, invoice, credit memo. ### Map item tax codes **Detail:** Assign Avalara tax codes to items or product groups so taxability is correct for each product type. ### Clean up addresses **Detail:** Ship-from and ship-to addresses must be complete and validated for accurate jurisdiction lookup. ### Load exemption certificates **Detail:** Link customers to certificates in Avalara and decide which system is the master for exemption status. ### Configure calculation points **Detail:** Decide whether tax is calculated on quote, order or invoice and whether it is recalculated on change. ### Test with representative cases **Detail:** Test multi-state shipments, drop ships, freight, discounts, returns and credit memos in a sandbox account. ### Reconcile before filing **Detail:** Compare ERP tax liability accounts to Avalara reports for a period before relying on filing. ## Pitfalls - Assuming the 2016 announcement means current support: the connector may be unmaintained for your LN version. - Items without tax codes default to taxable or non-taxable incorrectly, causing over or under-collection. - Freight and handling charges taxed differently by state are not mapped to a taxable code. - Credit memos and returns not sent back to Avalara leave filings overstated. - Timeouts to the tax service block invoicing unless a fallback is defined. - Exemption certificates expire in Avalara while the ERP still marks the customer exempt. ## Ai Layer ### Tax variance explanations **Description:** A private assistant reading LN invoices and Avalara transaction data can explain why the ERP tax amount differs from what was calculated: a missing code, an address issue, or a manual override. ### Exemption certificate monitoring **Description:** List customers who ship under exemption with expired or missing certificates, for credit and tax staff to follow up. ### Item tax code review **Description:** Suggest tax code assignments for new items based on description and product group, for tax staff to approve before they are set. ## Alternatives - LN's native tax setup is enough if you sell in a small number of jurisdictions with stable rates. - Other tax engines such as Vertex or Sovos may have better-supported connectors for your Infor version. - A custom call to the AvaTax API is an option when no connector exists, at the cost of maintaining it. ## Faq ### Does Avalara currently support Infor LN? **Answer:** A 2016 announcement named LN, M3 and SX.e among Infor products with Avalara integrations, but current support is unverified here. Ask Avalara which Infor versions have a maintained connector today before you commit to this approach. ### Is AvaTax only for cloud ERPs? **Answer:** No. AvaTax is a cloud service that on-premise ERPs call over the network. For an on-prem LN that means allowing outbound access to the service and handling the case where it is unreachable during invoicing. ### Does this cover VAT? **Answer:** This page focuses on sales tax as described in the record. VAT and cross-border compliance are a different scope, so check Avalara's coverage for your countries separately. ## Source https://www.cpapracticeadvisor.com/2016/07/12/avalara-adds-integrations-with-infor/22461/ ## Search terms avalara avatax syteline integration, avalara infor ln, avatax infor erp connector, infor ln sales tax software, avalara infor visual, infor m3 sales tax --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
