PaletteArena end of life:
Why it’s time to choose Medius over Rillion Prime
Rillion recently announced that PaletteArena will reach its end of life (EOL) on September 30, 2026. After that date, your PaletteArena software license will be terminated, and no support or maintenance will be available. Rillion is encouraging customers to migrate to its new cloud platform, Rillion Prime, but this isn’t as easy as flipping a switch. It’s a complete system change with new contracts, costs, and risks.
If you’re a current PaletteArena user, now is the time to re-evaluate your AP automation strategy. Rather than reinvesting in another Rillion migration, many finance leaders are moving to Medius AP Automation, a proven alternative that delivers faster ROI, stronger control, and long-term stability.
