Sidr ‑ Sales Tax Automation

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.

Best tax software i have worked with. Support is awesome and gets back to you quickly.

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

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.

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

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

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!

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.

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

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.

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

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

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

One of the best sales tax filing providers. Despite of filing your sales tax, they give bunch of help over the chat which worth of 1000$ or more!

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!

Sidr company helped me file my sales tax the same day I reached out. Their team responded very quickly and made the whole process simple and easy to understand. Compared to other services I’ve tried, their pricing is very affordable, and the experience was way smoother. Highly recommend to any store owner looking for fast and reliable tax filing help!

Out of all the apps I've used, this is by far the best. They make tax compliance easy. The customer service is the best I've experienced. Kevin has saved me tons of time and money. Thank you! Melanie, PF Wonder Salve

I read all of the outstanding reviews of SIDR tax and decided to work with them. As I worked to setup my sales tax account with SIDR, they were with me in the setup answering questions and making the setup very easy. We sell nationwide & their system tracks sales to all states & informed me as I reached states nexus. SIDR has filed three quarters for me on time, ensuring payments are made, my level of confidence in SIDR couldn't be higher not to mention my sales tax stress has ended as I am in capable hands with SIDR, couldn't recommend them more. Thank you
