What to do next
Start here
Upload your transaction data
Export your payments as a CSV from your system. Any format works — we read the columns automatically.
Drop your transaction file here
Or select it from your computer. You need at least a date/time column and a transaction amount. That's it.
A
Works with your export format
Column names like "txn_date", "transaction_time", or "date" are all recognized automatically. You don't need to rename anything.
B
Missing columns? No problem.
If merchant IDs or account numbers aren't in your file, those checks are skipped — you still get everything else.
C
We only use what you give us
Nothing is assumed or invented. Every alert is backed by data in your file. If it's not there, we say so.
