My online store is live and taking orders, but the checkout stalls whenever sales tax needs to be applied. The core payment flow works—until tax is calculated—so I need a specialist who can configure the tax rules correctly and ensure the payment gateway recognises them without errors. What has to happen: • Configure accurate sales-tax rules for local, national and international orders. • Sync those rules with the existing payment gateway so every transaction completes successfully. • Run sandbox test purchases across multiple regions, supply screenshots or logs that prove tax is added and the payment is captured. Once the changes are live, I expect a quick screen-share or concise hand-off note that shows me where the settings live so I can update future tax rates myself. If you have solid experience wrangling tax tables and gateway integrations on platforms such as Shopify, WooCommerce, BigCommerce or similar—and can turn this around quickly—let’s get started.

Hi, hope you're doing well! I can fix your checkout tax issue quickly and cleanly. I've worked with tax configurations and gateway integrations on Shopify, WooCommerce, and BigCommerce, so this is familiar territory. Here's my approach: - Diagnose the exact point where tax calculation breaks the payment flow - Configure local, national, and international tax rules correctly - Sync and test with your gateway via sandbox purchases with proof logs - Hand off with a clear note so you can manage rates yourself going forward A few questions to get started: 1. Which platform and payment gateway are you using, and do you have sandbox credentials ready? 2. Are there specific regions or countries where tax errors occur most often? 3. Do you have a deadline in mind, or is speed the main priority here? Let's get your checkout running smoothly. Azeem Amin

Good to see this project, I will configure your tax rules — local, national, and international — and resolve the gateway sync issue causing checkout to stall. I will also run sandbox tests across regions and document everything with a clear hand-off note. The stall likely happens because the tax calculation returns a format or field the gateway does not expect. I will trace the exact API response during tax lookup to pinpoint the mismatch. Questions: 1) Which platform and payment gateway are you using? 2) Which specific regions need tax rules configured? Ready to start whenever you are. Kamran
