How we ranked them
We ranked by how well each tool gets specific documents from clients and shares files back.
- We looked at requesting specific documents (one item per document, reminders, asking again), not just file storage.
- We also weighed security basics and whether the tool keeps an ongoing record per client.
- Prices are list prices checked in September 2026. Denby is our product, placed where we think it honestly belongs.
