Download a bill from the provider's app and upload the file itself, charges table readable; photographed screens, summary-only pages and others' bills are refused. Up to 100 per contributor come from a global base strongest in Southeast Asia, the United States and Europe, so dense Southeast Asian utility and telco tables sit alongside American and European formats, in several languages and currencies. Native text layer where the provider produced one; no field annotations. Proof-of-address documents are hard to source because every one is a name, an address and an account number on a page; for an onboarding vendor this is the proof-of-address training distribution; for a document team, a hard, table-heavy class with a usable license.
