Designing Your Business Model — Beyond Just Pricing

Pricing is a tactical decision. Business model is a strategic one. Founders who only think about pricing end up shipping a great product attached to a fragile, unscalable revenue mechanic — and wondering why growth stalls at £500k ARR.

The four levers of a business model

1. Value unit. What are you actually charging for? Per seat, per transaction, per outcome, per hour, per integration, per AI call, per asset under management, per ton of CO2 saved? The choice shapes everything downstream.

2. Pricing structure. Subscription, usage-based, tiered, freemium, marketplace take-rate, performance fee, hybrid. Each has profoundly different cash dynamics and customer behaviour.

3. Buyer. Self-serve individual user, departmental head, IT/procurement, executive sponsor, board-level. Each requires a different price point, sales motion and contract length.

4. Stickiness mechanic. Why does the customer not leave? Switching cost, network effect, embedded data, integration depth, contractual lock-in, habit. No mechanic = high churn = no compounding.

Common business model mistakes

• Per-seat pricing for a product that gets more valuable with usage (caps your upside).
• Pure usage-based pricing without a floor (revenue lurches month-to-month, kills planning).
• Freemium with no clear paid trigger (you build a charity).
• Selling to end-users when the buyer is the CFO (you waste cycles delighting non-buyers).
• Annual contracts billed in arrears (working capital nightmare for an early-stage business).

How to design yours

• Map the value created — what the customer measurably gets that they did not have before.
• Pick a value unit that scales with that value (not with your cost).
• Test 3 structures with 5 customers each — listen to what they push back on, not what they say they like.
• Model 24 months of cash and unit economics for each structure. The numbers usually pick the winner.
• Layer in stickiness deliberately — do not assume it appears.

Stage-appropriate models

Pre-revenue. Charge something. Even £100. The act of taking money changes everything you learn.

Early revenue (£0–£100k ARR). Concierge pricing — bespoke, high-touch, learning-driven. Standardise later.

Scale-up (£100k–£1m ARR). Crystallise 1–3 standard packages. Kill the bespoke. Start adding self-serve tiers if it fits.

Growth (£1m+ ARR). Optimise for LTV/CAC, expansion revenue and net dollar retention. Pricing reviews quarterly.
