Why Rex
How Rex helps enterprise AR teams
The problem isn’t strategy. It’s capacity.
CFOs know what would improve cash: tighter terms, faster collections, enforced contracts. Rex handles the long tail no one has time for.
AI that does the work, not just surfaces it
Rex handles execution end-to-end. Uploading invoices, sending follow-ups, validating POs. Your team steps in when judgment is required.
Deploy in days, not quarters
No migration, consultants, or rip and replace. Rex connects directly to your existing systems. Go live in days, see DSO improve in weeks.
