Tax Technology Services

Ryan provides a comprehensive approach to help our clients plan, select, and implement sophisticated tax technology solutions that deliver significant value to the global compliance process, from strategy and risk management to delivery. We have strategic partnerships with all of the industry’s leading tax technology software providers, and our experience with all the major ERP systems, as well as custom solutions and domestic and international tax systems, is second to none.

Technology creates no value unless it is thoughtfully and strategically deployed to maximize the efficiency and profitability of your business and tax operations. Whether it’s the automation of tax return preparation or the full-scale implementation of a tax decision-making software application, we ensure that our clients realize the full potential of their tax technology solutions. Our comprehensive tax technology service portfolio includes business process reviews, feasibility studies, implementation, automation, research, training and full technical support.

Tax Systems Implementation Services

Ryan’s Tax Systems Implementation services help clients realize the full benefits of their tax technology solution. We ensure the success of each project with proven service and implementation methodologies that are tailored to meet our clients’ needs at each stage of the process. We provide advisory services which can include requirements gathering, vendor selection, and the design of the solution itself. We deploy a holistic approach to software implementation and help our clients define and develop optimum processes, build business-relevant tax research, assist with interface design and development, configure and implement the tax technology solution, integrate tax returns, train system users, and manage the post-implementation processes.

TaxDecisionERP® Solution

Ryan understands that no matter how you do it, manual use tax calculation is difficult, error-prone, and labor intensive. It requires multiple transactions using varied tax rates based on where you buy, make, ship, warehouse, and sell, which leads to costly miscalculations. Manual processing gives you little visibility into your tax compliance and its impact on Sarbanes-Oxley reporting requirements. ERP systems may be good at many things, but they aren’t designed to track and manage use tax.

Ask yourself these key questions: 

  • How is your company currently calculating use tax in SAP?
  • Does Purchasing determine tax codes on the purchase order?
  • Does Accounts Payable assign tax codes on the invoice?
  • Are you using standard percentages and a little guesswork?

Your ERP System Isn’t the Answer
ERP systems may be good at many things, but, even combined with third-party tax calculation software, they aren’t designed to track and manage use tax. ERP systems lack functionality to deal with the complexities of the internal processes that are subject to tax, the number of product codes, and the intricacies of use tax rates.

Automating Use Tax Management Saves Money and Eliminates Errors
SAP users have a better solution for use tax management and compliance. TaxDecisionERP® is a comprehensive, multistate use tax decision automation solution that integrates with SAP ERP applications and external tax packages, enabling you to automate and centralize tax management by:

  • Establishing upfront product and tax rules
  • Supporting reconciliations and audits with real-time reporting
  • Adjusting tax-only debits and credits

Ryan’s TaxDecisionERP® performs the following functions:

  • Stops tax overpayment and avoids penalties from underpayment
  • Improves cash flow by paying tax on actual use rather than at invoice
  • Eliminates labor hours spent manually calculating and correcting use tax
  • Enhances audit and traceability tools for Sarbanes-Oxley documentation and control
  • Generates real-time calculations as goods are issued and services are delivered
  • Automates the multistate use tax process

Stop Tax Overpayment and Avoid Penalties
With the TaxDecisionERP® solution, you empower tax professionals with visibility and control, and give them the ability to enhance the bottom line. TaxDecisionERP® provides precise application of product codes, tax codes, and tax rules to automate tax calculations as use is determined. Our services include:

Business Assessment

  • Feasibility studies
  • Troubleshooting and evaluation services
