Contract Accountant at a tech vendor with 1,001-5,000 employees
Ensures customers with valid exemption certificates are not charged tax
Avalara AvaTax: * Automating the calculation of the tax charged on invoices. AvaTax interfaces with our accounting system, Workday. With AvaTax, we are confident that we are charging the correct tax. * AvaTax files our returns. We usually do not have to do anything except to ensure the sales information is in by the deadline and enter "multiple points of use" credits. * Record keeping: Avatax has all the returns that they filed available online, complete with back up detail, invoices, which clients had exemption certificate, etc. * When we have filed VDAs, AvaTax allows us to calculate correct taxes even for periods before we began using it, such as in cases where errors (e.g., incorrect tax codes) were made. Avalara CertCapture: * Keeps electronic copies of the exemption certificates. * Interfaces with AvaTax to ensure customers with valid exemption certificates are not charged tax(es). * Warns of expiring certificates. In addition to saving a lot of time in day-to-day operations and return filings, both these products can be very helpful in a sales tax audit.

Automated tax reporting has reduced manual work and supports accurate audit-ready filings
Thomson Reuters ONESOURCE Indirect Tax Determination has positively impacted my organization by shifting it from a manual process to a more automated process.That shift to automation has affected my team by improving efficiency; it reduced the amount of time it took my team to prepare to gather the information, review it, and report it on our sales tax returns, and it also cut down on some of the time that our other departments, such as accounts payable, had to review invoices. I have seen a return on investment, as we saved time; it took probably three weeks to prepare returns, and now we are able to do it in probably a week.
