1. The Flaw of Hourly Agency Billing
Traditional UK agencies bill between £120 and £250 per hour. This creates a fundamental conflict of interest: the longer an agency takes and the more scope creep that occurs, the more revenue they extract from your business.
2. The Fixed-Price Milestone Advantage
Under a structured milestone contract, every deliverable is specified in detail before work commences. Payments are tied strictly to verified milestones (e.g. Design Prototype Sign-off, Backend API Completion, Staging UAT, Final Live Deployment). If something takes longer than anticipated, the risk remains with the agency, not your company balance sheet.
