The teams behind indirect tax determination

Calculate Excise Taxes

"Going with IGEN was the best decision. Our implementation was not easy (including multi-state, multi-product, complex tax rules), yet they hit every milestone without delay. From a customer service standpoint, they always go above and beyond. I would describe the relationship more like a strategic partnership rather than a vendor/customer relationship."
