Credyt: Credyt charges $1 per Monthly Active Wallet with the first 10 active wallets free each month. At 100 customers the effective cost is $90 (90 paid wallets × $1). Payment processing fees from Stripe (or external PSP) are passed through without markup and are not included in Credyt's charge. Event total of 100K is well within the 1M free monthly allowance. Do not express as $0.90 per wallet — the pricing is $1/MAW with 10 free.

Flexprice: The canonical scenario (100K events/month) fits within both the Starter and Premium event limits (10M and 25M respectively). The Starter tier ($500/month) covers core billing, usage metering, wallets, and customer portal. Flexprice does not publicly confirm whether real-time prepaid credit balance, recurring wallet top-ups, and entitlement management require the Premium tier ($1,000/month); if so, effective comparison cost is $1,000/month. Annual billing reduces these by 20%. Payment processing fees are charged by the connected PSP at pass-through rates. The open-source self-hosted version is excluded as it does not include wallet and credit features needed for a like-for-like comparison.

Lago: Lago's cloud Business and Enterprise tiers both require a sales conversation; prices are not published. Historical community discussions reference a starting cloud price of ~$3,000/month. The AGPLv3 self-hosted core is free to run but does not include the customer portal, credit notes and refunds, automatic dunning, tax integrations, CRM/accounting integrations, Lago AI agents, or Lago Embedded. Self-hosting at this event volume requires Postgres, Redis, and compute for 5+ services plus engineering for setup and ongoing maintenance. Payment processing fees are charged by the connected PSP at pass-through rates.

Metronome: Metronome does not publish pricing. This scenario cannot be computed from public information. Payment processing is performed by the customer's PSP (typically Stripe) at the PSP's published rates; Metronome does not collect payments directly. Enterprise pricing requires a sales conversation.

Orb: Orb does not publish pricing. The ~$720/month platform fee estimate is based on previously public pricing captured by third-party analysis before Orb removed its public pricing page. Current rates may differ; Orb's $25M Series B (September 2024) and ongoing product expansion may have affected pricing. Payment processing fees are charged by the connected PSP at pass-through rates. A sales conversation is required for current pricing.

Stigg: Computed per-unit costs for this scenario total ~$192 ($32 per-customer × 100 + $160 seats), but the Growth plan has a $448/month contract minimum billed annually, making $448 the effective monthly cost at this scale. Enterprise subscription rate ($0.47/sub after discount) would increase per-customer costs if subscriptions are classified as enterprise. Scale plan requires custom pricing. Payment processing fees are charged by the connected billing system, not Stigg.

Stripe Billing: Starter plan at 0.5% is the lowest published tier; Scale plan would cost $16 (0.8% × $2,000) in billing fees before processing. Stripe Payments processing (2.9% + $0.30 per US card transaction) is an additional cost that varies by card mix; the ~$62 estimate assumes 100 transactions at average $20. Stripe Billing inherits Metronome's metering and contract tooling post-acquisition (completed January 14, 2026); integration timelines for combined features are not publicly dated.

About the canonical scenario

Every provider is evaluated against the same hypothetical: 100 monthly active customers, $2,000 in monthly recurring revenue, 100,000 usage events, and 5 seats. This scenario is not a typical workload for every provider — it is a normalisation device to make costs comparable across fundamentally different pricing models.

Payment processing is excluded from the total where it is not bundled — PSP fees (typically 2–3%) apply on top for providers that are PSP-agnostic. Canonical totals include only the billing platform cost. See each provider's footnote above for the full breakdown.
