LATAM context
PSE is operated by ACH Colombia. When you shop online in Colombia and choose "pay with PSE," you get redirected to your bank's page to authorize the debit. It's equivalent to a direct ACH transfer with the account holder's authorization.
Concrete example
On a Bancolombia statement, a PSE purchase shows up as: "DEBITO PSE - MERCADOLIBRE COLOMBIA - REF PSE: 12345678 - 250,000".
How it shows up on your bank statement
On Colombian statements, PSE payments appear as debits labeled 'PSE' followed by the name of the merchant or entity that charged you. The transaction ID shown on screen when you pay doesn't always make it into the statement, so reconciling usually relies on matching date, amount and merchant name.
How does finO$ handle this?
finO$ extracts the PSE reference, the associated merchant and the amount. It identifies recurring patterns for budgeting and categorization.
