Documents reach ADAM the way your suppliers and colleagues already send them: forwarded email, a message with a photo attached, PDFs, scans and spreadsheets. Nobody has to log into a portal, and no supplier has to change how they invoice you.
Where the data lives in a system rather than a document, ADAM can collect it from there instead. That includes a secure file drop you already publish to, a shared cloud folder, or a scheduled API pull from a platform you already run. That last one carries the most weight: an internal record from your own billing or ERP system becomes the expected figure a supplier invoice is tested against, so the check runs on your numbers rather than the vendor's. Each API connection is built for the system in question rather than picked from a catalogue.
Results travel the same way in reverse. Reconciled rows land in the spreadsheet your team already works in, exceptions arrive as an emailed report or a messaging digest, and where a finished record belongs in your own system, ADAM can write it there once a person has approved it.
