How to price AI-automation work: fixed, retainer or hourly

Price AI-automation work by matching the billing model to the certainty of the outcome: a fixed price when the scope is written and the result is measurable, a monthly retainer when you keep the automation running and improving, and hourly only for undefined work such as research or emergency fixes. Build the number from the hours you expect, the risk you carry, and the value the outcome has for that business, then write down what is excluded. This guide gives the method and the traps; it deliberately does not give you a rate.

Which billing model fits which work?

Most builders end up with a pattern: a pilot fee, then a fixed price for the full build, then a retainer. The pilot-to-retainer guide covers the transition.

How do you build a fixed price?

Start from hours, then adjust for risk and value. Never start from "what would they pay".

1. Estimate the hours by phase. Discovery and scoping, building, testing on real data, hand-over and documentation. New builders forget the last two and lose money there.
2. Add a risk margin. Unknown systems, messy data, a client who is slow to reply: each adds hours you can't see yet. A written scope reduces the margin you need.
3. Check against value. What does the outcome save or earn the business each month? A price far above a year of that value will not close; a price far below it leaves money and credibility on the table.
4. Write the exclusions. Everything not listed is not included. This sentence is worth more than any margin.
5. State the payment schedule. For a fixed price: part on start, the rest on the agreed "done". For a retainer: monthly in advance.

What goes into a retainer?

A retainer is not "unlimited changes". It is a defined service: monitoring the runs, fixing failures within an agreed time, a fixed number of small improvements a month, and a monthly note on what ran and what changed. Write those four items down with numbers ("up to two small changes, each under two hours"). Everything else is a new fixed-price add-on.

The client is buying the confidence that someone is watching. That is a real service; price it as one, not as a discount for loyalty.

The mistakes that cost new builders most

• Quoting before the audit. You cannot price what you haven't seen. The discovery-call guide gives you the questions.
• Pricing only the build. Testing on real data and hand-over are where automations succeed or fail; they are billable.
• Hourly for defined outcomes. It punishes you for being fast and makes the client watch the clock.
• Silent scope creep. "Can you also..." answered with "sure" instead of a two-line add-on.
• Underpricing the pilot to zero. A free build attracts clients who never commit; a modest paid pilot filters for the ones who will.
• No invoice discipline. In Israel, decide your business status and invoicing early; the Tax Authority publishes the current thresholds and rules for exempt and licensed dealers.

How to present the price

Put the outcome first, the model second, the number third. One page: what it does, what "done" means, what is excluded, the schedule, the price. Offer one alternative at most (for example a smaller pilot), not three tiers. When the client pushes back, ask what they'd remove from the scope rather than lowering the number for the same work.

Note AgeBridge never sets or suggests prices inside the product or on profiles. This guide is public editorial education; use it to build your own number.

Best fit and not a good fit

Best fit: builders with at least one documented pilot who want a repeatable way to quote. Not a good fit: looking for a "market rate" to copy. Rates vary by niche, speed and proof; your number should come from your hours and your risk, and it should rise as your proof grows.

What to do this week

Write your three models on one page: what a pilot includes, what a fixed build includes and excludes, what a retainer covers each month. Then price your last project again with the method above and compare it to what you charged.
