In Brazil, card sales are registered as receivables: money a merchant will be paid on a given date for a given card network. You get a CSV of transactions (customer, merchant, payout date, card type, amount) and a CSV of contracts in which a lender buys a merchant's receivable (contract ID, merchant, payout date, card type, amount).
- Sum the transactions into one receivable per merchant, card type and payout date, and print them as CSV sorted by ID, card type, date and amount.
- Apply the contracts: each one takes over the matching merchant receivable, which is then listed under the contract's ID instead.
- A contract may buy only part of a receivable: list the contract's share under its ID and keep the rest under the merchant, dropping the merchant row when nothing is left.
