Scored on 63 merchant reviews we hold for Sidr ‑ Sales Tax Automation, across five checks. Every figure is computed from those reviews — expand any row to see the counts behind it.





Computed from the 63 reviews we hold, with 12-month windows measured to 2026-08. This scores the public review record — it is not a review of the software itself, and a low score often means we hold little evidence rather than poor evidence.

The newest 8 of 63. Open one to read it in full, with the developer's reply where there is one.

Very pleased with this app and service. The online chat support is very responsive and helpful, and emails are always answered promptly. It's a big relief to be able to hand off this monumentally aggravating and time-consuming aspect of my business to experts, for a very reasonable price. The new flat-fee per-filing pricing is much easier to wrap your head around than the old hybrid system. I did have a few snags setting things up, and a few shortly after, but the Sidr team addressed everything and got it all taken care of in a reasonable time. Things have been running on auto-pilot since, and it has been a huge relief to not have to deal with sales tax myself any more.

Sidr is an excellent app for computing and filing required sales tax collected in Shopify. Sidr also makes the Registration of new required States simpler to apply. Their support is excellent and they respond quickly. It has made our collection and filing of taxes so simple. Sidr is also very competitive in the price of service they provide.

SIDR works well. Also, their online chat is very good, very helpful. Better to have the experts work on filing sales tax returns.

Great experience! Support is a very helpful and efficient. I'm happy to get sales tax filings off my plate and autofiled.

ABSOLUTELY amazing team and service. Sales tax is so scary when things go wrong but Sidr came in and manages our sales tax beautifully. Very attentive 10 stars

Great customer experience!

Carrie and our team are top notch! Couldn't ask for better help when it comes to our Shopify taxes!

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!
