Integrations: Avalara (AvaTax)

Overview

The Avalara (AvaTax) integration in CustomBooks™ enables automated sales tax calculation within our accounting system.

AvaTax is a cloud-based tax compliance solution that calculates real-time sales tax rates based on location, tax rules, and product taxability. When integrated with CustomBooks™, it helps ensure accurate tax calculations on transactions such as invoices, sales orders, and credit memos.

Setup Requirements

Before enabling the integration, you will need:
  1. An active Avalara AvaTax account
  2. Account credentials (Account Number, License Key, and Company Code)
  3. Proper tax configuration within your AvaTax account
It is recommended to coordinate with your CPA or tax advisor before activating the integration to ensure proper tax settings and compliance. We also highly suggest enrolling in Avalara University and completing the Avatax Learning Path, which will walk you through setting everything up in Avalara before you integrate your account in CustomBooks™.

Before connecting AvaTax to CustomBooks™, ensure the following information is properly configured in your Avalara account:

  2. Verify business details, such as company address and filing information, are accurate.

  1. Set up nexus jurisdictions (states or regions where you are required to collect sales tax).
  2. Ensure nexus settings match your business operations.
3. Tax Codes
  1. Assign appropriate tax codes to products or services within AvaTax.
  2. Verify taxability rules for each product category.
