Tax Rex ‑ Sales Tax Automation

Amazing app! I've wasted a week trying to make any sense of sales tax numbers (while being audited), until I found Tax Rex. I had to use their feature to request a report for an older period of time (unsupported by Shopify) and they completed it within hours, so I was able to submit all the information that I needed.
Also the reporting is presented in a meaningful way - you basically just copy/paste from their report into the tax people's system, it's as simple as that. Love it!
