Can Maditon compare suppliers before I buy?

Yes. A purchase project takes candidates from your register or from pasted addresses, reads their published documents and scores them against requirements — EU hosting, a DPA, no AI training on customer data, 72-hour incident notice, a transfer mechanism, plus your own. Every result shows the passage it was read from, and the decision you record closes the project and starts watching the chosen supplier.

A purchase project is how you compare candidates for something you are about to buy, and the record of why you chose one of them. It is built to hold up a year later, which is when it matters.

  1. Name the project after what you are buying.
  2. Add candidates, from the register or by pasting the addresses of a supplier you have never used. Pasted addresses register the supplier as under evaluation and start tracking its documents.
  3. Set the requirements. The built-in ones — EU hosting, a data processing agreement, no AI training on customer data, incident notice within 72 hours, deletion on exit, sub-processor notice, a transfer mechanism — are evaluated automatically from what each candidate has published. Add your own where you need them.
  4. Read the comparison. Each result shows the passage it was read from. Where the documents do not answer, the result is unanswered — a question for the supplier, not a fail. You can override a result by hand, and the override is recorded as yours.
  5. Record the decision — which supplier, and why. That closes the project to changes and starts watching the chosen supplier’s documents.

The report is a PDF in your language with the comparison, every finding with its quote, the requirement results including your manual overrides, and the decision with its reasons. Reports are archived as the file that was generated, so the document you show somebody later is the document that existed that day.
