Maxio
Maxio is the direct swap: billing, GAAP/IFRS revenue recognition and metrics in one platform, with published pricing from $599/month.
Formed from the 2022 SaaSOptics and Chargify merger, Maxio does the same core job as Subscript with a much bigger footprint: 85+ native integrations, 2,300+ customers and G2 Leader placements across six billing categories (4.3/5 from 829 reviews). Unlike Subscript, the Grow tier price is public.
The trade is implementation pain. Reviewers on G2 and TrustRadius report onboarding stretching past 10 months for some companies, support cases left open for months, and recurring invoice accuracy issues on usage-based billing. Subscript's weeks-long implementation is precisely the complaint Maxio buyers wish they could import.
