    Subscription

    Flat subscription

    One product, one price, billed monthly or annually.

    The original SaaS deal. You promise unlimited use, the customer promises a recurring cheque, and both sides pretend the cost-to-serve is constant. It works beautifully when your product has narrow surface area and your buyers want to stop thinking about it. It collapses the moment one customer uses 100× more than another and your gross margin starts choosing favourites.

    The mechanics
    MRR = subscribers × price

    Revenue is a function of logos, not load. Forecasting is a calculator.

    Wins
    • Single-product B2B with stable workloads
    • Buyer wants a fixed line item, not a meter
    • Cost-to-serve is roughly flat across customers
    Breaks
    • AI features land — inference cost dwarfs the price
    • Your top 5% of users consume 80% of capacity
    • Land-and-expand has no second motion

    Five mistakes that cost the most.

    Mistake 01

    The seven-tier pricing page

    Three tiers segment customers. Seven tiers paralyse them. Every additional tier doubles your sales-cycle length and halves the conversion rate of self-serve.

    Mistake 02

    Borrowing a competitor's model wholesale

    Their model is tuned to their COGS, sales motion, and ICP. You inherit none of those. You inherit the optics and the margin trap.

    Mistake 03

    Pricing the input, not the value

    Per-token pricing made sense when token cost was 80% of COGS. As models commoditise, charging per token charges customers for your supplier's choices, not your own value.

    Mistake 04

    Treating overages as punishment

    If your customer success team has to email apologies when usage exceeds the included pool, your pricing page is misframing your own product.

    Mistake 05

    Locking pricing in code

    Every model above will need to change within 18 months. If a price change requires a deploy, you do not have a pricing strategy — you have a pricing release schedule.

    Pick a model. Stress-test the math. Then change it next quarter.

    Every model on this page will need to evolve within 18 months. Our pricing engine lets you switch, A/B, and migrate models without a deploy — so the choice you make today doesn't lock you in.
