We resolve these error messages daily for our clients.
A whole exchange, wallet, or time period missing from the import, often without any error message. Balances look plausible but are incomplete and distort every calculation.
Many fail to upload their exchange CSVs or fill CoinTracking's manual template and map everything correctly. TX-Partner handles format, columns, and mapping.
Holdings in your dashboard or balance-per-exchange overview don't add up or turn negative? Then the transactions are incomplete or misassigned.
Learn moreCoinTracking's "Missing Transactions" check (Analysis → Checks): deposits and withdrawals without a transfer counterpart, caused by bridges, scam tokens, or incomplete API imports.
Learn more"Show warnings" flags "Short (Warning)" and unrealistic gains: a sale without a matching buy sets the cost basis to 0. The cause is the data, not the tool.
Learn moreCoinTracking's "Duplicate Transactions" check finds what overlapping CSV and API imports created twice. TX-Partner cleans it up.
Tax reports are only as good as the underlying crypto accounting. TX-Partner analyzes the root cause behind every error message.
CSV imports from different exchanges overlap, duplicates creep in. CoinTracking cannot automatically determine which data is correct.
Wrong timestamps, typos in amounts, swapped exchange names – manual entries are error-prone and lead to incorrect results.
Exchange APIs are often incomplete. Old transactions are missing, DeFi swaps are not exported. What the API doesn't deliver won't appear in CoinTracking either.
CoinTracking classifies transactions automatically, but is often wrong. A "transfer" is classified as a "trade". This massively distorts the tax burden.
Whichever level you start at, the result always meets the TX Documentation Standard. You decide how deeply TX-Partner gets involved.
TX-Partner is your contact for crypto accounting, your crypto tax software and everything that requires transaction data. Personal, experienced, on equal terms. Just what customers also report.
"I felt very well taken care of at TX-Partner. Initially I was in panic because lots of things didn't add up in CoinTracking. Many errors, including missing cost basis. Luckily, with the help of Johannes and Robert, everything was sorted in short time. I am very grateful and can recommend TX-Partner unreservedly."
"Top job. Quick and simple handling. Very good work."
"The collaboration is really enjoyable, and I notice that this year I am much less worried about handling my crypto accounting myself."
"My Blockpit report showed several discrepancies, especially unlabeled transactions and balance warnings. The support was competent and helpful."
"I have been in crypto since 2017 and honestly never documented anything. TX-Partner looked at it and gave me a clear overview of how to approach this."
"My crypto transactions were entered cleanly, fully and traceably in Blockpit. Saved me a lot of time and effort."

"I did not know exactly where I stood. TX-Partner reviewed my data and explained clearly where I am and what to watch out for."
