Vetoed by codeClose and accounting Start from this workflowMore for asset management What it decides ## Narrow questions, each with a check behind it. Whether a price move or stale price is explained Vetoed by code: tolerances, second source. Code can't prove the answer right, but it can prove it wrong: an amount out of range, an impossible date, a name not on the document. Many settle; the rest go to a person. | Reads | Prices from two sources, the NAV, last period's prices | Produces | Approved NAV, exceptions | Who signs | A person on your team, with every figure traced to its document and every call on record | Process | Close and accounting | Industry | Wealth, asset management and fund administration See it run ## Every line, decided where it's safest.

Nothing settles below the cutoff, or when the check disagrees. The item goes to a person in the inbox with what the engine saw, its best answer and the runner-up. The person's ruling is kept and tunes the next run. How are its judgements checked? Code can't prove the answer right, but it can prove it wrong: an amount out of range, an impossible date, a name not on the document. Many settle; the rest go to a person. Can we change it to fit how we work? Yes. Start from this workflow and describe your differences in plain words. The design assistant revises it, the validator checks it, your expert reviews it on the canvas, and your admin publishes it. Does it read our files as they are? Yes: spreadsheets and CSV in any layout, PDFs, bank formats and e-mail attachments. Sumarity suggests how each column maps, proves the mapping on a sample and remembers it once a person confirms it. Where does our data go? Sumarity runs in Zurich. Your data, backups and logs are stored in Switzerland. How does it get better? Your team's rulings become an answer key. Better questions and cutoffs are proposed, tested on data they haven't seen, and published only when your admin approves. It improves itself, with permission. ## Start from this workflow. Run it on your data. A pilot runs alongside your own process for a few weeks, at our cost, and ends in a line-by-line comparison. Talk to usBack to the library
