What AI can actually do for a small business, and what each job costs

The jobs AI does well are the boring text jobs you already do

AI writes first drafts of the text your business produces every day: replies to inquiries, follow-up emails, notes after a call, quote descriptions, and plain-English explanations of documents. It does not run your business, find you customers, or replace your judgement. Think of it as a fast assistant who never saw your shop and needs everything handed to it.

What that looks like in practice:

• A wedding photographer gets an inquiry at 11pm asking about availability, packages, and travel. She pastes it in with her price sheet and gets a reply draft that answers all three questions. She edits two lines and sends it.
• A body shop owner dictates messy notes after looking at a car: "rear bumper cracked, left quarter panel dent, needs blend into door." AI turns that into clean quote line descriptions the customer can actually read. He still sets the prices.
• A physio clinic uses it to rewrite the intake form and the post-visit care email so they read like a person wrote them, not a lawyer.
• A contractor pastes in a 14-page subcontract and asks which clauses cover payment terms, change orders, and who carries liability for delays. It points him to the right pages in a minute. He still reads those pages himself.

The pattern is the same every time. You supply the facts, AI supplies the wording, and you check it. Jobs that fit that shape are worth doing with AI. Jobs that don't fit it usually disappoint.

What each job costs when you pay the API directly

When you use your own Claude or ChatGPT API key, you pay per token, which is roughly three-quarters of a word. Input (what you paste in) is cheap. Output (what it writes back) costs more. The table below uses Anthropic's published rate for its mid-tier Sonnet model when we checked, $2 per million input tokens and $10 per million output tokens. Token counts are our estimates for a typical version of each job. Your own will vary, so treat these as order-of-magnitude figures.

That is a busy month. Three hundred AI-assisted tasks cost less than a sandwich. A cheaper model such as Claude Haiku or a "mini" OpenAI model costs a fraction of that again, and is good enough for short replies and summaries.

Compare that with a ChatGPT Plus or Claude Pro subscription at $20 a month each, or with the AI add-ons now sold inside booking, CRM, and email tools. Check your own software bills for any line labeled AI or assistant. If you pay for two or three of those, you are likely paying several times what the underlying AI costs.

Prices change, so check the current numbers on the Anthropic pricing page or the OpenAI API pricing page before you trust ours.

What AI will not do for you, despite the pitch

The jobs AI is most often sold for are the jobs where it lets small businesses down.

• It will not bring you customers. A pile of AI-written blog posts or social captions does not create demand. Generic AI text reads as generic, and your customers notice. Use it to answer the people who already contacted you, faster. That is where it pays.
• It does not know your prices, policies, or schedule. If you don't paste them in, it will make something up, confidently. Every reply that quotes a price or a date needs your eyes before it goes out.
• It is not a calculator you can trust unchecked. It can lay out a quote, but totals, tax, and discounts should come from your invoicing software, not the model's arithmetic.
• A website chatbot is rarely worth it for a small shop. Most visitors want a price, a booking link, or a phone number. A clear page with those three things beats a bot that answers in paragraphs.
• It should not see patient or sensitive client data by default. Clinics in the US should not paste identifiable patient information into any AI tool unless they have a signed business associate agreement covering it. Write the template with AI, then fill in the patient details yourself.
• It won't answer your phone in most setups. If missed calls are your real leak, a dedicated AI phone-answering or receptionist service is the better buy than any text tool.

How to try it this week without signing up for another subscription

Pick one job from the table, the one that eats the most of your evenings, and run it with AI for two weeks. For most owners that is inquiry replies.

1. Create an API account with Anthropic or OpenAI and generate a key. This is separate from a $20 chat subscription. You pay only for what you use.
2. Set a monthly spend limit in the account's billing settings. $10 is plenty for a trial and means a mistake can't run up a bill.
3. Write a short "house facts" note: your services, prices, hours, service area, and how you like to sign off. Paste it in with every request, or store it wherever your tool keeps instructions.
4. Use it for one job only, and edit every draft before it goes out.
5. After two weeks, open the usage page in the API console. You will see your real cost per job instead of our estimate, and you can decide whether to add a second job.

You can use the key in any tool that accepts one. Fynl is built around this: the CRM, booking, quotes, and Gmail-connected email all use your own Claude or ChatGPT API key, so the AI cost is whatever your console shows, on top of $49 a month for the portal. Fynl does not do SMS or phone calls yet, so if texting customers is central to how you work, factor that in. The point is the same wherever you run it. Own the key, see the real bill, and stop paying a markup on a penny-per-job service.
