Some vendors never attach anything. They mail "your invoice is ready", or nothing at all, and the invoice waits behind a login. Seeing "OPENAI CHATGPT SUBSCR" on a statement is enough to say which page it is on, and that turns a dead end into a one-click errand. Deliberately not what Presto does. They log in for you across a thousand portals, with a desktop app so credentials never leave the machine. Holding a customer's supplier passwords is the expensive and legally heavy half of that product, and skipping it costs little of the value: knowing *where* is most of it. The lookup runs at read time and nothing is stored against a transaction, so adding an entry fixes every ledger at once, retroactively, with no migration and no backfill. A supplier added today starts answering for purchases made last year. Eighteen entries, ordered by how many companies actually pay them, measured across production ledgers and cross-checked against a customer poll. The two agree closely: Google and OpenAI lead both by a wide margin. Measured coverage: 769 of 10 182 undocumented purchases, which is 7.6% of rows but 120 of 224 companies, so more than half of all companies have at least one purchase this can now answer. Two things it refuses to do. It offers nothing for payments that have no invoice, reusing the rule that already keeps the hunt from searching mail for salary and tax: a link there implies somewhere to go. And longer aliases win, so a Google Cloud bill is not sent to the Workspace console. Vendors whose billing page could not be pinned down were left out rather than guessed at, including some with real volume: Fortnox, Apple, Klarna and Mynt. A wrong URL is worse than a missing one, because it spends the trust the feature runs on. Every entry here still deserves a human clicking it before anyone relies on it. No interface yet: this is the data and the lookup, so the workspace can use it the day it lands.
