Indirect Tax Responsibilities

Aligning business, IT and tax

The alignment of your business with your IT and Tax, without forgetting the importance of master data. We’ve dealt first hand with tax automation pain-points: lack of communication between departments (being informed late or not at all), inadequate master data, and the difficulties surrounding determining the right solution.

Determining Indirect Tax (GST/VAT/SUT)

Implementing sustainable solutions in the (ERP) systems is often a challenge. Historically, certain processes will have been created and systems will have been configured; multiple patches will have been applied, resulting in incomprehensibility for the tax, IT and finance teams. Leading to difficulties when trying to reach a single source of truth: where the tax treatment, customer facing documents, and reports all contain the same – correct – data.

Reporting and Compliance

It all concludes with tax reporting: ensuring the right reports for VAT, GST, SUT and other Indirect Taxes are available in your system(s); ensuring Intrastat reporting and other registers/ledgers can be easily reconciled to your tax reports; and having all your transactions on hand either in SAF-T or other types of audit files that are required by law.


What we offer is our best. Our promise to you is that you will receive nothing less than that.
Check out our services and contact us to start the conversation!


We perform health checks on existing VAT, GST, and SUT system set-ups; we assist in Tax Technology vendor/solution selection processes; and we offer Tax Automation implementation services. At Tytho, we are able to assist you in order to achieve compliance by implementing process changes and/or solutions.


Do you recognize the "if only I knew how to..." feeling? Well, we can provide you with specialized Tax automation training that is tailored to your needs. We offer, for example, training on SAP & Tax, OneSource (including Global Next) and Vertex (including Accelerator) in our own environment.


Through gaining an understanding of our clients needs and all the best practices, we have been able to develop solutions within SAP that are very close to standard SAP. Our products include: Tytho ITL Determination, Tytho ITL VAT number validation tool, and Tytho ITL tax codes with validity periods.


We have the resources and more importantly expertise to offer both functional and technical support. Regardless of if you have chosen our Tytho ITL solutions, those of our trusted partners, a native ERP or a custom-built solution; we can provide the support you need.

Our products

Tytho ITL Determination
Our Indirect Tax Logic (ITL) determination tool provides a comprehensive solution to Indirect Tax determination within SAP and Tax Automation software. The tool consists of three elements: unique state-of-the-art determination, one single source of truth, and practical and complaint VAT accounting. Indirect Tax determination can be complex, and an out-of-the-box ERP system like SAP has its limitation. Tytho ITL can offer a user-friendly solution that integrates into your SAP system, delivering accuracy that standard SAP cannot without additional tax parameters. Furthermore, Tytho ITL stores all relevant Indirect Tax data in one location, aligning sources to provide one transparent overview. Lastly, Tytho ITL is a sustainable solution: addressing ERP system errors with long-term solutions.
Tytho VAT number validation tool
Our tool executes the VAT number check – that is required by EU law to ensure that the VAT numbers of your customers and vendors are correct – within SAP; thus eliminating the need to go via the VIES website. The Tytho VAT number validation tool has three functions. Firstly, it can check the VAT numbers as they are added to the customer or vendor master data. Secondly, it can run a report based on a select range, which compares the data in SAP with the VIES database. This report reviews the VAT number, company name, and company address, storing the results in SAP to ensure you have a proper audit trail. Thirdly, it can include a check within the transactional process, for example during invoice creation. In conclusion, instead of using time and resources to manually check master data, allow Tytho to provide the solution to your VAT number validation process.
Tytho ITL tax codes with validity periods
Our Indirect Tax Logic (ITL) tool offers a third type of tax code (standard SAP only offers two types of tax codes), which is non-jurisdictional tax codes with validity periods. In fact SAP’s limited number of tax codes, 1296 to be precise (without special characters taken into account), make Tytho ITL validity periods a valuable tool. The implementation of our product allows the user to have a start and end date on every tax code, reducing the quantity and increasing the accuracy of the tax codes used. This tool reduces tax code maintenance costs, whilst allowing for configuration of complex multi-rate codes and more. Find out what else we can do by getting in touch today.
