B2B SaaS billing and financial operations platform combining Chargify billing with SaaSOptics revenue accounting.
Maxio is the merger of Chargify (subscription and usage billing) and SaaSOptics (SaaS revenue accounting), sold as one financial operations platform for B2B SaaS. It handles the billing side — plans, usage events, proration, invoicing — and the accounting side — ASC 606 revenue recognition, deferred revenue schedules, and GL sync — plus the SaaS metrics reporting (ARR movements, retention, cohorts) that boards and investors ask for. Its typical buyer is a growth-stage B2B SaaS finance team that has outgrown spreadsheets and Stripe-native billing but is not ready for an enterprise ERP.

Scored against UsagePricing's Usage-based billing & metering rubric v1.0 (0 weak · 1 adequate · 2 strong), assessed July 2026. Requirements we couldn't verify from public material stay unscored — never guessed. Read the method.
| Requirement | Score | Why |
|---|---|---|
| Real-time balances & drawdown Can a customer (and your product) see an accurate credit or spend balance mid-period? | 1 · Adequate | Balance and credit handling at subscription grain. |
| Correction & re-rating When a meter was wrong, can you fix history without hand-editing invoices? | 1 · Adequate | Adjustment-based corrections. |
| Commits, credits & custom rate cards Can it express how enterprise AI deals are actually signed? | 1 · Adequate | Ramps and contract terms via the SaaSOptics lineage; usage commits are lighter. |
| Billable-metric flexibility Can finance define a new meter without re-instrumenting the product? | 1 · Adequate | Events-based billing supports standard aggregations. |
| Invoice & proration correctness Do mid-cycle changes, consolidation, and multi-currency come out right? | 2 · Strong | Strong B2B invoicing with proration and consolidation for finance-led SaaS. |
| Rev-rec & ERP handoff Can the numbers survive an audit once they leave the billing system? | 2 · Strong | Rev-rec is core DNA — the SaaSOptics half of the merger. |
| Ingestion scale & integrity Does the meter stay correct at production event volumes? | 1 · Adequate | Built for B2B SaaS volumes, not event firehoses. |
| Price-change velocity How fast can you ship a pricing change safely? | 1 · Adequate | Catalog changes are governed; live-data simulation is limited. |
Maxio's distinct position is covering billing and revenue accounting in one system, so an invoice, its rev-rec schedule, and its ARR impact stay consistent without reconciliation glue. Competitors tend to pick a side — billing platforms bolt on rev-rec, subledgers bolt on nothing — while Maxio was assembled from a strong product on each side.
Platform fee, sales-quoted. Sized to billings under management.
Both, which is the point. It bills customers and simultaneously keeps the revenue schedules and deferred revenue balances your accountants need, syncing journal entries to your general ledger. You still keep a GL like QuickBooks or NetSuite underneath it.
It supports usage components and events-based billing well for typical B2B SaaS meters like seats, API calls, or transactions. If your model is high-volume real-time metering with credits and commits, a dedicated metering and rating layer is usually a better center of gravity, with Maxio-style tools downstream.
