Compare the Artist-Patron Register
Other companies offer provenance systems that involve buying special stickers or stationery that you can use to authenticate artworks. These are primarily focused on photographers who have unique challenges preventing unauthorized copying of their work since every photo print is identical.
We believe that Fine Artists really need a process that organizes and manages your art business efficiently while improving the quality of your work's provenance as a by-product. Our focus is primarily on serving the Artist and Gallery. That said, registration of serially numbered, hand-signed COA certificates in a database is an excellent and completely sufficient record of fine art provenance.
