Quick Answer

Cost depends on risk, not just screens

  • AI prototype: GBP 5k-15k
  • AI SaaS MVP: GBP 15k-45k
  • Production SaaS: GBP 45k-150k+
  • Enterprise AI platform: scoped after discovery

An AI SaaS app costs more than a traditional dashboard because the product has to manage prompts, model selection, data quality, usage costs, evaluation, security, failure handling, and customer trust. A simple wrapper around an AI API can be quick. A reliable product that customers pay for needs stronger architecture, monitoring, onboarding, billing, admin tools, and a plan for model changes.

The main cost drivers are user roles, data sources, AI workflow complexity, integrations, privacy requirements, model usage volume, and how much human review is needed before an AI answer reaches the end user.


How to control the budget
Start with one valuable workflow, one clear user type, and one measurable outcome. Build the smallest version that proves customers will use it, then add automation, analytics, and advanced AI features after the workflow is validated.
