Our Verdict
The choice between QuiXcel ZATCA connector and Tax Rex ‑ Sales Tax Automation depends entirely on the merchant's location and tax obligations. If a Shopify merchant operates in Saudi Arabia and needs to comply with ZATCA's e-invoicing regulations, QuiXcel ZATCA connector is the only relevant option, despite the lack of reviews. If a Shopify merchant operates in the United States, Tax Rex is the clear choice. Its strong reviews and focus on US state sales tax compliance make it a much safer bet for those merchants.
Given the complete absence of reviews for QuiXcel, Saudi Arabian merchants should proceed with caution, verifying all claims independently and potentially starting with a test store before integrating with their live operations. US merchants can confidently use Tax Rex because of its proven track record.
