How Determination can be a part of your business’s technology transformation.

When you’re a growing company, it’s usually a time of technological transformation – moving from manual processes to automated ones as your business expands. But if that transformation is done piecemeal, or if tax isn’t brought to the table, you can be left with disparate systems that don’t talk to each other, creating more work for your team. If your company is looking at new technologies to support run-the-business activities – whether that be a new ERP, ecommerce, or finance system – it’s usually the best time to also talk about your tax needs. ONESOURCE Determination seamlessly integrates with many systems on the market today, allowing regulatory updates, jurisdictional changes, and other tax policy data to be added and applied throughout your organization from a centralized, cloud-based hub.

By integrating ONESOURCE Determination with your business systems, you can reduce time, effort, and risk posed by manual processes or disconnected solutions. Plus, you can easily apply your tax policy consistently across your business and collaborate across regions with our cloud-native solution. 

ONESOURCE Determination integrates with a wide variety of business systems, so your transaction tax data can flow back and forth with ease. Less manual pushing and pulling of data means less risk and less time your team is spending on repetitive work.

With our robust API and integration offerings, you can add new capabilities and connect to new technologies your company invests in faster than ever before. Instead of disconnected nodes spread across your company, you can be sure you’re building a solution that can flex and be as nimble as you want to be.

By integrating your tax engine with an ERP system, you can apply your tax policy consistently with less effort. With an integrated solution like Determination handling your sales tax calculations, any type of tax policy that applies to a business can be quickly captured and applied, providing a single source of truth for all tax calculation and reporting.

When we expand, the tax system will already be in place. To have that essentially done effectively and correctly already is a huge bonus.

How Determination can support your business as it expands into new markets.

It’s exciting to be part of a growing company, watching as it expands into new opportunities and reaches new customers. But from a tax perspective, expansion can also be challenging, especially if you have a small team. Individual states, counties, and cities have their own ever-changing rates for taxable transactions, and as you grow, it can quickly become overwhelming to keep up with these changes and filing requirements. ONESOURCE Determination has content coverage of thousands of jurisdictions, both in the US and internationally, to support you wherever you go. And our cloud technology means that no matter where you do business, ONESOURCE remains a central source of truth, accessible wherever you need it.

How Determination can help you reduce risk & limit tax audit exposure.

ONESOURCE Determination ensures you get sales and use tax right the first time, every time, while keeping track of shifting regulations, so that you can reduce the risk of costly penalties and reputational damage. Because calculating taxes correctly isn’t just a matter of getting the math right - it's vital to the health of your organization. Inaccurate tax calculations can be costly, and can inhibit your organization’s ability to plan, grow, and adapt to changing market dynamics. Tax errors can also result in penalties that impact your bottom line and can even affect public perceptions and customer loyalty.
