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 that no one has time for.

AI that does the work,
not just surfaces it

Rex handles execution. Uploading invoices, sending follow-ups, validating POs. Teams step in when judgment is required.

Deploy in days,
not quarters

No migration, consultants or rip and replace. Connect your existing systems. Go live in days, see DSO improve in weeks.
