Worked very well the first year, tougher the next but likely due to my trading complexity
Date: Apr 27 2026SummaryFor all my portfolio stuff, this is a wonderful platform.
For leveraged/trading, it works, but not as user friendly. It could be some settings that need to be tweaked, but my trading wallets had shown the wrong balances. I would have had to go into each transaction to make manual changes. It's possible that the trading platform I used reported items like "Hit TP", "Hit SL" differently or in a way that's not easily translatable to the platform. As such, I left 4 stars.
Also, the AI bot support chat thing was exceptional. It was able to process a refund on a subscription I forgot about!
Above average and is more than enough for the average investor. Thank you SUMM!PositiveAesthetically pleasing platform
Discount via Coinbase
Caught things I had missed
Easy to make changes
AI Bot Support Chat very good!NegativeNo advanced subscription renewal notice

Works great, support was prompt.
Date: May 16 2026SummaryOverall a good deal for the money. I can't imagine most people having more complicated taxes than mine. However, even in my case I was able to get my issues resolved quickly.
PositiveImported all of my wallets easily, when some were wrong I was able to get help from Karl. My problem was a little complicated but still resolved in a couple days.
NegativeSome transactions were counting outputs as fees and this caused the txns to show a "zero cost buy" which inflated my balances.

PositiveVery quick response and came up with the solution. Gilbert worked through the files I uploaded and advised to remove two columns, UID and MEMO.
NegativeIt looks like SUMM had not updated their rules to accept MEXC downloads of withdraw transactions. Got there in the end

PositiveSuper easy to use and import data. Can even go back a few years if required and get tax statements from previous FY's.
NegativeI've stopped trading crypto and thus don't require the use of this service. This isn't a con at all, just me sharing an experience - I got charged for another subscription and did a live chat with the AI bot online. Subscription was refunded within a day. Thanks for being streamlined!

Very good product.
Date: Apr 28 2026SummaryExcellent.
Nothing has ever gone wrong for me with this tool.
It's done exactly as I've wanted it to as a crypto trading hobbyist.
If I scaled up my business endeavours to professional trading, I would still use this tool. It's that reliable.
I'd just need to upgrade my yearly subscription and it would be "plug and play" so to speak.PositiveEverything feels modular and interconnected.
There is a high-quality customer support bot and human assistance where it's needed.
The calculations are accurate and the tool corrects errors that I had no clue about.
I completely trust this tool because it's earned it, through good results and quality, especially for the price.
This tool has a massive range of support and integrates well with other tools like TurboTax!NegativeI noticed that one article, specifically about importing into TurboTax, was not kept up-to-date and so I had to figure out a big problem myself when the article could've took hours off of my workload.

I found the same with overly optimistic sync time estimates.
The tool read that sync could take as long as 5 minutes.
It took probably about an hour or longer for a few accounts, presumably because the service is very busy during the end of tax season.
I spent a long time troubleshooting but if I knew that it would just take more time, that would have cut down a lot of my workload.
But, because of the excessively optimistic time estimate, I thought there was a bug and wasted twice or three times the amount being stumped and getting frustrated on what's going wrong. -

Capital Gains reconciliation and complexity
Updated: Jun 03 2026SummarySo far excellent, I am close to finishing my reconciliation of 22,000+ transactions with SUMM becoming my source of truth . Their support is not only responsive but knowledgable and efficient
PositiveCame across some difficulties in editing some transactions, and took some time to ask support the questions in detail. After a very short time , ie 20 minutes I had a concise explanation and walk thru to explain how to change and edit various transactions and which ones. I was able to complete quickly. I am sure this would have taken days to achieve. This is one of the reasons why I have subscribed with Summ and moved off a couple of other platforms where the shortfalls would have limited my ability to complete the tasks efficiently
NegativeNot sure yet, I am sure will find something but a little early still

Got Me Out of a Hole! Only a week to my tax deadline and 1,200 transactions to report!
Date: Jun 22 2026SummaryVery Good. I had a lot of data to process in a short time. It all had to be checked and reconciled, which both sides did in tandem to resolve the matter over a weekend.
PositiveSwift, clear answers. Worked with me. Felt like I was dealing with a human (I will never know!). Very pleasant to work with.
NegativeNot a lot to criticise really. Just a little on the pricy side for an occasional user such as myself. I have only used the product for 3 days and will wait and see whether I will renew next year.

Summ is a huge time and worry saver
Date: Jun 11 2026SummaryI've been using Summ to manage and analyse a large cryptocurrency transaction history, and it has saved me a huge amount of time.

The interface is intuitive, and importing data is straightforward. Customer support has also been responsive when needed.
