How Statemio reads Discover statements

Discover card statements are read with the cardholder sign convention (purchases negative, payments positive) and checked against the account summary.

Statemio has a layout-specific reader for Discover credit card statements. We regression-test it on synthetic statements modelled on the bank's published layout. Banks change their layouts, so we never assume it worked: the balance check tells you on every file.

The balance check

Opening balance + every transaction must equal the closing balance (for credit cards, previous balance − payments + charges = new balance). If the totals don't match, you see a red badge and the rows that break the running balance, before you download anything. Pages from statements that don't balance aren't counted against your allowance.
