Vital signs

Why it's on the table

On the table, Payments (Pa) is seat 34 of 58, in the Sales & Revenue family. It is a stable element — the category has settled, choosing is cheap, and switching is rare. Pick a holder and move on; this is not where your decision budget should go. It is marked essential: a company that leaves this seat empty is running with a gap that compounds. It sits in the lowest paid band — lunch money against the hours it returns.

Payments: the top 5 — v2026.Q3

Edition v2026.Q3 · ranking, pricing and status verified 2026-08-06.

1. 1StripeStripe, Inc.

   Cards 2.9% + 30¢ (+1.5% intl) · Billing 0.7% PAYG or from $620/mo · Managed Payments MoR +3.5% · Metronome startup tier w/ $100K allotment · agentic Shared Payment Tokens $0.15 each

   Best for The default revenue stack for an AI-era startup — checkout, subscriptions, usage meters, tax, and agent-facing commerce on one API you'll never fully outgrow.

   Businesses on Stripe generated $1.9T in 2025 (+34%, 1.6% of global GDP) and its Revenue suite is tracking toward a $1B run-rate. It bought Metronome (Dec 3, 2025) — the layer that bills OpenAI, Anthropic, and NVIDIA — and co-authored the Agentic Commerce Protocol with OpenAI, powering ChatGPT Instant Checkout. Every upgrade path (MoR via Managed Payments, usage billing via Metronome, machine payments via x402/MPP) now lives in-house.

   Watch Fees stack: Billing + Tax + Radar + Managed Payments can push all-in cost past a flat-fee MoR. Not a merchant of record by default — you carry global tax liability unless you pay the +3.5% Managed Payments adder. Complexity is real; small teams routinely underestimate the integration surface.

   $1.9T total payment volume in 2025, +34% YoY — ~1.6% of global GDP (annual letter, Feb 2026) [src] · $159B valuation via employee tender, Feb 2026 — up 70% from $91.5B a year earlier [src] · Metronome acquired Dec 3, 2025; Revenue suite on track for $1B annual run-rate; ACP live in ChatGPT Instant Checkout since Sep 2025 [src]

2. 2PolarPolar Software (open source, Apache-2.0)

   Starter free, 5% + 50¢ · Pro $20/mo, 3.8% + 40¢ · Growth $100/mo, 3.6% + 35¢ · Scale $400/mo, 3.4% + 30¢ · startup program: 12 mo free at Scale rates

   Best for Solo devs and small AI teams who want a merchant of record — sales tax, VAT, chargebacks handled — plus usage, credits, and LLM-token billing without building any of it.

   The MoR built specifically for AI-era software: meter tokens, API calls, and GPU time down to the event, with LLM billing wired into the Vercel AI SDK. Open source (Apache-2.0, ~9.9k GitHub stars) with a $10M Accel-led seed (Jun 2025) and users like Tailwind CSS, FastAPI, and Midday. It compresses Stripe + tax + entitlements + metering into one checkout.

   Watch A seed-stage company sitting in your entire revenue path — counterparty risk is the honest price. Fees run 1–2 points above raw Stripe, and the May 2026 'Polar Plans' repricing added monthly platform fees where a flat 4% + 40¢ used to be.

   $10M seed led by Accel (Jun 17, 2025) [src] · ~9.9k GitHub stars, Apache-2.0, active releases through May 2026 [src] · Tiered MoR pricing 3.4–5% + 30–50¢ incl. tax/VAT/chargebacks; LLM token metering via Vercel AI SDK (Aug 2026) [src]

3. 3PaddlePaddle.com Market Ltd

   5% + 50¢ per checkout (all-in: MoR, global tax, fraud, support) · custom rates at scale · sub-$10 products and invoicing need a quote

   Best for SaaS and app businesses past first revenue that want the proven merchant of record — one vendor eating tax, compliance, chargebacks, and support across 200+ markets.

   The scaled MoR: 10,000+ businesses, $130M in sales taxes remitted last year, customers from Fortinet to Tailwind Labs and n8n. It won the vibe-coding wave's distribution prize — 'Lovable Payments, powered by Paddle' makes it the default checkout for prompt-built apps — and its App2Web push targets the Apple-tax arbitrage every consumer AI app now runs.

   Watch 5% + 50¢ is the priciest headline rate in this table, and onboarding involves real vetting — approval isn't instant. It's a packaged platform, not a primitives API: deep custom billing logic fits Stripe or a billing layer better.

   10,000+ businesses; 190M transactions processed; $130M sales tax remitted last year (site, Aug 2026) [src] · 5% + 50¢ pay-as-you-go all-in MoR pricing (Aug 2026) [src] · 'Lovable Payments, powered by Paddle' — MoR checkout embedded in the leading vibe-coding platform (2026) [src]

4. 4OrbOrb → Adyen (closed Jul 1, 2026)

   Custom (Core / Advanced / Enterprise), priced on invoice billings + events ingested — no public rate card

   Best for Series A+ companies whose pricing IS the product — usage, credits, prepaid thresholds, hybrid seats — and who keep their own payment processor.

   The reference usage-billing platform for AI infrastructure: Vercel, Replit, Supabase, Fal, and Writer run on it, it's stress-tested past 250,000 events/second, and it shipped agentic payment-method support (shared payment tokens) before any rival. The Adyen acquisition (closed Jul 1, 2026) puts a payments giant behind it while Orb pledges standalone operation and processor neutrality.

   Watch No public pricing — expect a sales cycle and real invoices. Acquisition integration risk is unproven despite the neutrality pledge; the Metronome-into-Stripe precedent shows independents get pulled toward their owner's rails. Overkill below ~$1M ARR.

   Acquisition by Adyen closed Jul 1, 2026; Orb continues as a standalone, processor-neutral product [src] · Customers incl. Vercel, Replit, Supabase, Fal, Writer; stress-tested to 250,000+ events/sec (Aug 2026) [src] · First billing platform supporting agentic payment methods / shared payment tokens (2026) [src]

5. 5LagoLago (open source, AGPL-3.0 core)

   Open-source self-host free (AGPL-3.0) · Lago Premium (cloud or self-hosted) custom, with paid add-ons for premium ingestion, tax, 24/7 support

   Best for Teams that must own the billing stack — self-hosting, EU data residency, gateway neutrality, or pricing logic too weird to rent.

   The open-source billing engine AI's fastest companies actually run: Mistral AI, Groq, Gladia, Synthesia, and Laravel are customers. AGPL core with 9.7k stars and steady releases (v1.46, May 2026), metering-to-invoice in one self-hostable stack, and payment-gateway orchestration across providers — the only top-5 path with zero platform lock-in.

   Watch The gap between the free core and Premium is wide, and Premium pricing is opaque contact-us territory. Self-hosting billing is genuine ops burden — dunning, tax, and invoice edge cases become your on-call problem.

   Customers incl. Mistral AI, Groq, Synthesia, Laravel, OVHcloud (Aug 2026) [src] · AGPL-3.0 core, 9.7k GitHub stars, 185 releases, v1.46.0 shipped May 13, 2026 [src]

Payments: the top 8 compared

Edition v2026.Q3 · ranking, pricing and status verified 2026-08-06.

How to choose your payments

If you're pre-revenue or unsure what your pricing will be

Stripe. 2.9% + 30¢, usage meters included, and every future need — MoR, Metronome-grade usage billing, agentic checkout — is an upgrade, not a replatform. One in five Atlas startups now charges within 30 days of incorporating; be one.

If you're a small team selling AI software globally and refuse to touch VAT registrations

Polar — the 1–2 point MoR premium is cheaper than compliance, and LLM-token billing comes free. Creem or Dodo if you want a flat-fee indie alternative.

If you're past ~$1M ARR with a subscription product and want one vendor liable for tax, fraud, and chargebacks everywhere

Paddle — 10,000+ businesses and $130M in tax remitted last year say the model works; or Stripe Managed Payments (+3.5%) if you're already deep on Stripe.

If usage, credits, or outcome pricing IS your product (AI infra, agents, GPU time)

Orb if you're enterprise-track, Metronome-inside-Stripe if you're all-in on Stripe rails, Lago if you must self-host. Prepaid credits with threshold billing are the 2026 default for controlling fraud and runaway spend.

If you want agents to buy from you — or your agent to buy things

Implement ACP product feeds + Stripe Shared Payment Tokens today (that's the only rail live in ChatGPT), support x402 for machine-to-machine API payments, and watch AP2 — but don't bet the stack on any protocol yet; even Stripe puts the industry at level 1–2 of 5.

Payments: the category in numbers

Edition v2026.Q3 · ranking, pricing and status verified 2026-08-06.

• Stripe processed $1.9T in 2025 (+34% YoY, ~1.6% of global GDP); startups hitting $10M ARR within three months doubled YoY; Feb 2026 tender valued Stripe at $159B (+70%) [src]
• Independent usage billing got rolled up in under a year: Metronome → Stripe (Dec 3, 2025), Orb → Adyen (closed Jul 1, 2026), m3ter → Salesforce, OpenMeter → Kong — Lago is the last major independent [src]
• Three agent-payment protocols are racing: ACP (Stripe+OpenAI, live in ChatGPT Instant Checkout since Sep 2025), AP2 (Google, 60+ partners, now under FIDO), x402 (Linux Foundation; 75.4M transactions and $24.2M volume in 30 days, self-reported Aug 2026) [src]
• Stripe's Revenue (billing) suite is on track for a $1B annual run-rate — billing software is now a unicorn-scale line item inside a processor [src]
• Merchant-of-record went mainstream in 2026: Stripe launched Managed Payments (+3.5%) and re-platformed Lemon Squeezy onto it (Jan 28, 2026); Paddle passed 10,000 businesses and powers Lovable Payments [src]
• Even Stripe places agentic commerce at 'level 1–2 of 5' maturity (2025 annual letter) — early adopters are retail brands (Etsy, Urban Outfitters, Coach), not yet the long tail [src]

Payments: method & sources

Ranking criteria: time-to-first-dollar, fit for usage/credit/AI pricing, global tax exposure, agent-readiness, and lock-in cost — editorial, no affiliate consideration. The MoR debate resolved honestly: an MoR (Polar/Paddle/Creem/Dodo, or Stripe's own Managed Payments) charges 1–2.5 points over raw processing to take tax and chargeback liability off you; below ~$500K revenue that trade is almost always right, and Stripe now plays both sides of it. Conflict resolved: metronome.com still presents as independent with its own 0.8%-of-billings pricing, but Wikipedia (Dec 3, 2025 acquisition) and Stripe's own pricing page (Metronome startup tier) confirm Stripe ownership — we report it as acquired-and-operating. Orb–Adyen terms are undisclosed; only the Jul 1, 2026 close date is from Orb's own post. x402's 30-day volume figures are self-reported dashboard numbers — directionally real, not audited. Paddle's '190M transactions' homepage stat is undated. Weak-source flags: FastSpring, Zuora, and PayPal entries rest partly on pre-2026 knowledge plus live-site checks. Adjacent elements: Stripe Atlas incorporation → In · Incorporation; Mercury/Brex/Ramp → Bk · Banking; bookkeeping and revenue recognition → Ac · Accounting; Lovable itself → Vb · Vibe Builder; CRM handoff of paid accounts → Cr · CRM. Stablecoin rails (Bridge, Privy — both Stripe-owned) are deliberately footnoted here: they matter to agent payments but aren't how a startup charges its first customer. Ranking criteria: verified commercial traction, independent satisfaction surveys, agent benchmarks, and founder-fit (price floor, lock-in, surfaces). Editorial, never paid — the charter. Machine-readable twin: pa.json.
