E-commerce Sales Tax Setup Fix

Job ID: 40402224

Budget: $15 – $25 USD

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.
