I'm looking for a big sample of accounts (payable or receivable) or bills. No matter if it's structured data, scans, or physical receipts.
I haven't found data more relevant than government contracts. But contracts usually include a bulk of goods and services, and it's difficult to separate those.
Some firms use software to manage their accounts, but that's closed data, even when exportable.
Do you have any hints where I can get it anyway?
