MM Mark M. Global Intercompany & Transfer Pricing Supervisor; Robotics Process Automation Business Leader Enterprise (\> 1000 emp.) 10/17/2019 "Thomson Reuters Onesource - One Stop Shop" 3.5/5 What do you like best about ONESOURCE? Thomson Reuters is an industry leader in the provision of tax application software. We subscribe to everything from Tax Provision to Tax Compliance to Transfer Pricing Compliance applications. Thomson Reuters provides a solid platform, capable of completing various tax related compliance efforts. They have an excellent support staff that is ready and willing to help if you get stuck. Their customer relations personnel is friendly, helpful and not pushy. Review collected by and hosted on G2.com. What do you dislike about ONESOURCE? When you have a company as large as Thomson Reuters, inevitably things will slip through the cracks. One of the things that frustrates me is that because of its size and it's efforts to reach every consumer, oftentimes the software is frustrating to use because it is slow and difficult to understand and use. Simple things like finding the correct location to enter information is not intuitive. We find "phantom" checkboxes that we can't uncheck. It oftentimes leads to calls to the help desk to find out where to change these items. This can be very frustrating in crunch time. By trying to provide software to every known tax possibility, they often overlook, or don't fleshout, the most important parts of the software. Review collected by and hosted on G2.com. What problems is ONESOURCE solving and how is that benefiting you? All income tax compliance, transfer pricing, BEPS compliance, and tax provision work is completed in Onesource.

I can rely on this software to have the forms I need for tax purposes. Review collected by and hosted on G2.com. What do you dislike about ONESOURCE? 1) Customer Service - Thomson Reuters must develop a user-friendly platform for users to seek assistance with software issues and inquiries, as the Community Center, Help Center, and call lines are consistently inadequate. The Help Center fails to provide relevant search results, and customer service representatives are slow, rude, and unhelpful. The software frequently experiences downtime and glitches. Additionally, some tax forms lack properly programmed calculators, resulting in incorrect calculations. Review collected by and hosted on G2.com.

Show More Validated ReviewerSource: Organic TJ TJ J. Enterprise architect Enterprise (\> 1000 emp.) 1/23/2019 "Great data with reasonable API capabilities" 4/5 What do you like best about ONESOURCE? Most accurate and up to dated tax rate data, updated and maintained accurately. My last company using Thomson Reuters ONESOURCE data to support tax calculation in global (north America) sales and indirect Tax. ONESOURCE provides most reliable tax rate data at granular level (zip code) and provides periodic updates. This is very important and critical from accurate tax calculation and compliance perspective. In early days, ONESOURCE implementation was a nightmare. Due to the lack of APIs and Web services, we had ONESOURCE data file downloaded and loaded into our CRM and then used homegrown services to support sales applications. In 2016, we replaced that process once ONESOURCE provided effective APIs in their cloud based tax automation initiatives. APIs are pretty good, reasonably fast and provides necessary information to your sales applications (mobile, e-com) for tax calculation. We were able to seamlessly integrate ONESOURCE with our Mobile, e-com with little effort. Pretty good reporting, easy to schedule and download report in different format like CSV, Crystal report and Pdf Review collected by and hosted on G2.com. What do you dislike about ONESOURCE? SOAP based web services are bulky and less efficient. Though response time is reasonable but could be much faster. I like the data, accuracy of data. updates but their technology investment is a big question. While integration with SAP systems was fairly reasonable, ability to integrate with custom CRM system is nightmare. Review collected by and hosted on G2.com. Recommendations to others considering ONESOURCE: Pros: best and accurate tax (sales and indirect) data with regular update. Cons: Bulky SOAP based web services and little hard to implement with custom CRM Review collected by and hosted on G2.com. What problems is ONESOURCE solving and how is that benefiting you? Sales tax and Indirect Tax calculation for north America region. Must be accurate and compliant with local regulations. Review collected by and hosted on G2.com.

"Works Good if not the best" 3.5/5 What do you like best about ONESOURCE? The best thing what I like about this product is that this is fully integrated with the native SAP application. The results of any tax impacts at the Order level or billing level is quick and no need to wait. Moreover this has done away with the tax jurisdiction code which I believe was not a very good solution from maintenance perspective. Review collected by and hosted on G2.com. What do you dislike about ONESOURCE? It's not working to meet all the typical business requirements especially for the contract cases where there are material as well as service component. Also would like to have their reporting module beefed up with more reports and some EWS. Review collected by and hosted on G2.com. Recommendations to others considering ONESOURCE: This is a well integrated package when used with SAP. I would suggest you to have clearly defined business requirements before you engage the consultants to implement the OneSource otherwise it will fall short of the expectations.

I was recently a first time user of ONESOURCE a few months ago. I have used multiple other programs like Prosystem Fx Tax and CorpTax, but both have a distinctive learning curve to them. The immediate integration of the working trial balance within ONESOURCE Income Tax has been greatly beneficial. It allows the end user to easily find errors and fix problems with ease.
