That was emphasized by the sales tax software company’s purchase of Transaction Tax Resources for about $377 million earlier this month. With the separately developed, ATR, businesses can create, modify, and apply business and taxability rules that can be used before and after a tax calculation occurs. They can also define and relate tax content decisions with ERP and other systems at the business process and transaction level. The ATR software provides three core features: Find and replace which can be used to create custom rules to modify tax calculation based on line-level fields within an invoice or other transaction values; Allocations and aggregations means products and services taxed differently when sold in a bundle or used in multiple tax jurisdictions can now be allocated in AvaTax. Finally, reference lists permits the uploading of data from other systems to AvaTax with the ability to write data-driven rules to ease the setup of taxability rules.
