Sidr ‑ Sales Tax Automation

So far we love Sidr. Registering in different states is really confusing and comes in staggered long timelines. Their chat and staff patiently guide you through. They're wonderful

Sidr is very prompt and knowledgeable and has done an excellent job handling our Colorado Sales tax filings which was such an impossibly difficult process for me previously! Definitely worth it! So happy with the Shopify integration. It has made life much better!

They don’t just file your sales tax—they become a real support partner for your business. Their team consistently goes above and beyond, offering fast, detailed, and genuinely valuable guidance over chat. The quality of help they provide easily feels like a consulting service, and they deliver it with patience and clarity every time.

Great application! Especially for California, this will streamline and simply your tax reporting - making you and your bookkeeper happy!

5 stars aren’t enough!
Excellent and professional service. We are in different countries, and whenever I email them， even during their off-hours, they still reply and never leave me waiting because of the time difference. I really appreciate their help.

Great price for tax prep work, and they hunt down very problematic issues as needed!

Very helpful and nice customer service, and I especially appreciate their attention to detail.

Very functional and easy to use, support always here to help. thank you

Sidr has been SO helpful and easy for managing all of our sales tax - the team are also amazing, I've never experienced customer service like this before! Highly recommend!
