Real-time billing, built for AI
AI products incur real costs in real time. Traditional billing doesn't. AI products incur real costs in real time. Traditional billing doesn't.
In 2025, credit-based pricing models grew 126% compared to 2024. This post explains the three pricing models that work, when each one breaks down, and why billing infrastructure matters more than you think.
Why does traditional SaaS pricing fail for AI products?
A $29/month subscription made sense when serving one more customer cost you nearly nothing. AI products don't work that way. Every API call costs money. Every token generated, every inference run, every GPU second consumed: these are real costs that happen in real time.
Traditional billing collects revenue at the end of the month. Your infrastructure costs happen immediately. This gap creates cash flow risk that can break your business before it scales.
Data from PricingSaaS' "Pricing Trends" report backs this up. In 2025, packaging events surged 21% year-over-year. Pricing events rose 15%. Companies stopped debating $19 versus $29 and started rebuilding their entire monetization model. The pricing structure matters exponentially more than the price point.
What are the three pricing models AI products actually use?
Hybrid subscription plus usage
Base subscription covers platform access. Usage-based pricing handles AI features. Figma and HubSpot both adopted this model. You get stable recurring revenue with consumption-based upside.
When it works: You have venture backing or healthy margins. You can front infrastructure costs during billing cycles without sweating cash flow.
When it breaks: A customer burns through $500 in API costs. You collect revenue 30 days later. You're carrying that risk. For bootstrapped founders, this kills profitability before you reach scale.
The overage model variant creates different problems. When Cursor introduced usage limits to what was previously unlimited, the backlash was immediate. Reddit threads and YouTube videos filled with discussions about which competitor to switch to. When users don't have good visibility into spending or don't get notifications, surprise bills destroy trust.
Credit systems (prepaid consumption)
Customers buy credits upfront. They spend credits as they use your product. OpenAI's API, Claude API, and Perplexly all use variations of this approach.
When it works: Cash flow risk disappears. You collect payment before costs hit. Customer spending stays within known bounds.
When it breaks: Credit implementations vary wildly. Fixed allocations, prepaid pools, monthly refreshes, rollovers: there's no established best practice yet. Most founders underestimate the complexity. Authorization logic, wallet state, grant lifecycles. Each creates edge cases that compound. Developer forums are full of posts like "billing is a distraction" from founders trying to figure out whether to price by API calls, GPU usage, or tokens.
Outcome-based pricing
Charge for measurable outcomes, not inputs. Intercom charges $0.99 per resolved customer service conversation. Not per message. Not per token. Per actual outcome.
Reddit is full of stories where this approach works. A founder building a GPT-based support tool wrote: "We started with pay-per-token but customers had no idea what that meant. Switched to per-conversation resolved and churn dropped." This shift from raw usage to measurable results makes billing a product problem, not just a finance one.
When it works: You have crystal-clear, measurable outcomes customers understand. The value calculation is obvious. Customer service resolutions, document processing completions, successful API integrations.
When it breaks: Outcomes are fuzzy or hard to measure. Internal resistance runs deep. Intercom's CFO called it "uncomfortable and scary" even with CEO-level conviction. Their resolution rate improved from 25% to 70% over three years. They restructured sales compensation and accepted margin pressure throughout. Most teams don't have that runway.
Why do margins matter more than you think?
Founders optimize for adoption. They keep prices low. They don't track profitability per customer. When costs scale with usage and revenue is fixed or delayed, you can grow yourself into bankruptcy.
The margin challenge is uniquely difficult for AI products. Costs are directly tied to third-party LLM usage. Model pricing changes. Context windows expand. Customer behavior shifts. Any of these can destroy your unit economics overnight.
Intercom uses 12+ different models optimized for different conversation types. Most indie hackers can't build that level of sophistication. You need visibility into costs at the event level. Monthly billing summaries arrive too late.
What does building billing infrastructure actually cost?
The biggest time sink isn't deciding what to charge. It's building the infrastructure to support your pricing model.
Real-time authorization. Check balance before allowing usage. Immediate deductions. Debit the wallet as usage happens. Cost tracking at the event level. Know your margin per request. Flexible top-ups and limits. Let customers add credits, set spending caps. Hybrid models that combine subscriptions with usage.
Traditional billing systems weren't designed for this. Stripe handles subscriptions and one-time payments well. It doesn't handle consumption that happens in real time.
Most teams underestimate the surface area. Authorization logic. Wallet state. Grant lifecycles. Edge cases compound. You build yourself into a corner and spend months unwinding it later.
How often should you change pricing?
Continuous pricing iteration has become standard. Particularly for AI products where underlying economics shift as models improve and costs change.
Three principles matter:
Revenue timing matters as much as revenue amount. Collecting $100 upfront is fundamentally different from collecting $100 at month-end when you've already fronted infrastructure costs.
Limits are conversion opportunities. When a customer hits a usage limit, you have a signal about engagement and an opportunity to convert them to a higher tier. Only if your infrastructure can detect and respond to those moments in real time.
Simplicity beats precision. Intercom kept pricing at $0.99 per resolution even though some conversations cost more than others. Complex pricing creates friction. Friction kills adoption.
Why we built Credyt
Dozens of founders hit the same wall. They spend weeks building billing infrastructure. They take on cash flow risk. They lose visibility into margins. We built Credyt to solve the underlying problem.
Real-time billing infrastructure for AI products. Credyt handles wallet balances, usage authorization, immediate deductions, and cost tracking. You focus on building your product instead of reinventing billing systems.
We're not replacing your payment provider or invoicing system. We're adding the missing layer. Real-time control over usage and monetization that matches how AI products actually work.
The hard part of monetizing AI isn't just picking a price. It's building infrastructure that aligns your costs, your pricing, and your cash flow in real time.

This matches what I have seen on the API gateway side too. The hard part is not only charging before cost happens; it is explaining the cost after a request moves through routing.
For AI products, usage authorization and wallet debits become much more useful when they include model route, provider or channel, retry count, fallback path, and the balance bucket that paid for the request. Otherwise prepaid credits solve cash flow but still leave the user asking why a run consumed what it did.
That is one reason we separate the accounting language in Tokens Forge: official/direct balances, lower-cost route balances, API key or project attribution, and per-run accounting for heavier researcher-style jobs. Same general lesson as your post: billing has to become part of the product surface, not just a Stripe event after the fact.
