Level 1: subscriptions
Business-tier AI assistants and AI features inside your existing software are priced per user per month, in the range of a phone plan rather than a consultant. For most small businesses this level already delivers hours of saved time per employee per week, which makes the math easy.
Level 2: configuration
The middle level is connecting AI to your own knowledge: a chatbot fed with your FAQ, an assistant that knows your product documentation, automations between your existing systems. Expect a one-time setup effort, either internal time or a small external project, plus the ongoing subscription costs.
Level 3: custom builds
Custom AI agents and integrations are a real software project: engineering time is the dominant cost, and maintenance continues after launch. The rule of thumb that keeps budgets honest: a custom build should earn itself back within a year in saved hours or added revenue, otherwise stay at level 1 or 2.
The hidden costs to plan for
Training time for your team, cleaning up the data an AI will rely on, and review time for AI output. These are not reasons to wait; they are simply lines that belong in the plan.
FAQ
What is the cheapest way to start?
One business assistant subscription for the two or three people with the most repetitive text work. Measure saved hours after a month, then decide the next step.
When does custom AI make sense?
When a process is unique to your business, runs at volume and demonstrably hits the limits of standard tools. Prove the pattern with off-the-shelf software first.
Are there ongoing costs besides subscriptions?
Yes: someone maintaining prompts and workflows, and periodic re-evaluation of tools. Budget a few hours per month, not a full role, at small scale.
