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

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 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

The perfect 5 5-star reviews average on the App Store for Sidr Tax is well deserved. If you are a store owner and are serious about staying sales tax compliant, then you really need to consider working with Sidr Tax. SUPERB service from Tongbo, Kevin and their team. So easy to work with. Great Chat Service. Very very responsive ( I don't think they ever sleep :) .....and most of all - their app is so easy to use , logical, clear and very user friendly. I cannot recommend Sidr Tax enough to other Shopify Store owners. So happy we found this great company!! Keep up the great work Tongbo and Kevin!!

Wow - this is a 5 star app. Set up is a breeze and the service is fantastic. Highly recommend if you need to file sales tax in more than your own home state.

There needs to be an option for 10 stars! Our bookkeeping team decided to start using Sidr for a new client rather than a competitor that we are using for an older client, and it has been a world of a difference. First of all, the user interface is much more clean and less overwhelming than the competitor. This includes the means of populating reports should you be filing returns manually, but we decided to go with the automatic filing. Second, the costs are much more reasonable. Third, the tutorials and help articles are immaculate - it feels like they're reaching out and holding your hand personally to walk you through all steps of the infernal sales tax processes. Lastly, and most of all, the support we've received from Tongbo and Kevin from Sidr have been nothing short of magical. The patience, understanding, and ridiculously speedy communication we receive from them make dealing with sales tax matters feel like a walk in the park. We can't recommend Sidr enough!

Working with Sidr has been an amazing experience! From the very beginning, they were incredibly helpful with setting everything up and getting my sales tax ID — they practically handled it all. Their responsiveness is top-notch; any questions I had were answered quickly, and any issues were resolved immediately (Caused by me, not them). I was really stressed about managing sales tax reporting, but finding this company has been such a relief. If you're considering working with them, don’t hesitate — it’s truly a 100% stress-free experience. You won’t be disappointed!

As a small business owner, I’ve always been cautious about delegating critical tasks, yet managing the increasing demands of growth can be overwhelming. That’s where SIDR has been a game-changer. Their automation and expert guidance on Nexus and sales tax have streamlined a complex process for me. As my business has expanded, I’ve entrusted them with filing taxes across multiple states—and I plan to add more this year. Their seamless service and reliability have earned my trust, allowing me to focus on scaling my business while leaving state tax compliance in the hands of true experts.

This team has made sales tax (something I was so worried about) so simple. The auto file has been a weight off my mind, and when there was some confusion about having duplicated my license, this team chased down the issue (over the course of almost a full year!) and followed up constantly until the problem was solved. I highly recommend Sidr Tax to anyone considering bringing a sales tax solution into their Shopify platform.

Working with Sidr App has been great! This service is exactly what I was looking for. I love the reports and can see how many products were sold by each State. The support is Very good. My first retail tax payment was just made by Sidr and I didn't have to do it. Thank you Tongbo for getting that all wrapped up! Feels great.

Tongbo and his team have been great with responding fast and filing sales tax return for us on time. I am glad we are using your service :)

Incredible support and service! onboarding was quick and seamless.

Great App and Amazing team, super helpful and super fast in communication.
