Tax Rex ‑ Sales Tax Automation vs WebPlanex: GST Invoice Indiafor Shopify (2026)
Tax Rex - Sales Tax Automation and WebPlanex: GST Invoice India, while both listed under the 'Finances' and 'Taxes' categories in the Shopify app store, cater to entirely different markets and tax systems. Tax Rex focuses exclusively on US state sales tax automation, offering features like automated filing, accurate reporting, economic nexus alerts, and simplified state registration. Its target audience is US-based Shopify merchants struggling with the complexities of sales tax compliance across multiple states. It even accommodates ignoring orders imported from marketplaces such as Amazon and Ebay. WebPlanex: GST Invoice India, on the other hand, is designed for Indian merchants dealing with Goods and Services Tax (GST). Its strength lies in generating GST-ready invoices directly from Shopify order data, providing sales reports required for GSTR-3B and GSTR-1 returns, and supporting multi-location fulfillment with varying GST numbers. Its feature of e-Invoice json generation makes it quite specific for the Indian market. The key differentiator is their geographic focus, Tax Rex on US sales tax and WebPlanex on Indian GST.

Our Verdict
The choice between Tax Rex and WebPlanex is entirely dependent on the merchant's location and the tax system they need to comply with. If you're a US-based Shopify merchant grappling with sales tax in multiple states, Tax Rex is the clear choice due to its focus on US sales tax laws, automated filing, and economic nexus alerts. Its ability to exclude marketplace orders could be a huge time-saver.
However, if you're an Indian merchant navigating the complexities of GST, WebPlanex: GST Invoice India is the better option. Its features like GST-ready invoice generation, sales reports for GSTR returns, and multi-location fulfillment support are specifically tailored to the Indian GST system. The large number of reviews may also indicate a more established solution in that market.
