Vivi was absolutely lovely and so helpful! She handled my subscription issue quickly and professionally, and made the whole process smooth and stress-free. I really appreciate her kindness, patience, and excellent customer service. Thank you so much, Vivi! 💜

SUMM used to be a good service, but lately the user experience is flawed by frequent errors and glitches, and by a customer service which is getting worse and worse. It’s a pity.

Very quick response with fair ,professional and polite attitude . Can not ask for more

10/10 Direct, fast and helpful service from Vivi

Great experience using Summ for handling tax reporting across multiple accounts and entities. I’m on the Investor Plan, and the platform makes tracking and consolidating crypto transactions smooth and straightforward. A special shoutout to Vivi in customer support—she was super helpful, responsive, and resolved my request quickly. Fantastic customer service!

I had to cancel my annual subscription right after it renewed and asked for a refund. Vivi from the support team handled it quickly and was kind and understanding the whole way through. She made what could have been a stressful process really easy. Great customer service, so thank you, Vivi!

I've had a great experience with Summ, especially their customer support.

Vivi was incredibly helpful, friendly and professional, resolving my questions quickly and efficiently.

I was also impressed by how quickly the technical support team identified a token mapping issue and escalated it for resolution.

It's reassuring to know there's a knowledgeable and responsive team behind the product.

Excellent customer service overall. Thank you, Vivi and the Summ team!

I had initially purchased a plan but got overwhelmed trying to reconcile thousands of complex on-chain DEX micro-transactions and reached out to support, Vivi went completely above and beyond to make sure I had what I needed so I could handle my transactions properly. You rarely see this level of understanding and genuine care in SaaS support. Thank you, Vivi!

Timely response.

Vivi was very helpfull and quick to fix problem

Vivi was very quick and comprehensive in their responses!

Fantastic customer support. I had fairly complex crypto needs with a custom .csv with my transactions. They were able to help me process this and were available for customer support throughout troubleshooting with me live until we had resolved the issues. Cannot thank them enough

Before you changed to Summ, you ran a great website, support was great and everything else was really good. Now its turned to crap, you can't even login to the website using the Google option. Cant reset password, whatever you changed, revert it, its trash.

an overpriced money grab. I do not know how they get away with the prices and subscription format.
