Our Verdict
The choice between Sidr ‑ Sales Tax Automation and Xendo IOSS for UK Sellers is entirely dependent on the merchant's geographical location and the sales tax jurisdiction they need to comply with. If you're a US-based merchant struggling with the complexities of US sales tax across multiple states, Sidr Tax, with its fully managed approach and nexus tracking, is the clearly superior choice, despite the lower number of reviews on Xendo. However, if you are a UK-based merchant selling goods to EU customers and need to handle IOSS compliance efficiently, Xendo IOSS is the only relevant solution. Its flexibility and ease of use, with no registration needed, make it ideal for UK businesses navigating post-Brexit EU trade regulations.
Common Questions
Does Sidr Tax handle IOSS for sales to the EU?
No, Sidr Tax is specifically designed for US sales tax compliance.
Can Xendo IOSS handle US sales tax?
No, Xendo IOSS is designed exclusively for IOSS compliance for UK sellers exporting to the EU.
What if I need to comply with both US sales tax and EU IOSS?
You would need to use both apps, Sidr Tax for US sales tax and Xendo IOSS for EU IOSS, or explore other integrated solutions that offer both functionalities. Be cautious of solutions that don't specialize, as tax law varies greatly between regions and countries.
Is Sidr Tax suitable for small businesses?
While the description doesn't explicitly state suitability for small businesses, its focus on automation and ease of use suggests it is likely suitable for businesses of varying sizes, particularly those needing assistance with complex sales tax requirements. The chat support feature can be especially helpful for new or small business owners.
What are the potential downsides of the 'No Contract' offered by Xendo IOSS?
While 'No Contract' offers flexibility, it also means that the pricing or availability of the service could change more frequently. Merchants should monitor Xendo IOSS for any such changes to ensure continued compliance and cost-effectiveness. Also, be aware that discontinuing the service means assuming the responsibility of IOSS tracking and filing, which can be complex.
