How do I hire someone to build an AI agent for my business?
Decide first whether ready-made software covers your job; if it does not, hire a freelancer for one small, well-defined agent, or a specialist team when the agent must connect to your ERP, run on your servers or be maintained for years. Start with one paid pilot on your real data, and put code, hosting, testing, approvals and maintenance in writing before the full build.

Software, freelancer or team
| Option | Fits when | Watch out for |
|---|---|---|
| Ready-made software (invoice OCR, chatbot builders) | Your job is standard and the product already does it | Monthly fees per user or document; your process bends to the product |
| Freelancer | One small agent, clear inputs, low risk, a short project | One person for build, security, testing and support; availability later |
| Specialist team or agency | Several systems, ERP integration, your own servers, ongoing changes | Higher starting cost; check that the people who pitch are the people who build |
| In-house hire | Agents are core to your business and there is enough work for years | Hiring time, and one person rarely covers models, integration and operations |
What to put in the contract
- The architecture: written in code, or built on a no-code platform. If you want no Zapier or n8n dependency, say so.
- Where it runs: their cloud, your cloud account, or your own servers, and which model provider, if any, sees your data.
- Who owns the code, the prompts and the data, and what you receive at the end.
- Which actions need human approval: payments, postings, messages to customers, deletions.
- How it is tested: on your real past cases, with an agreed accuracy check before go-live.
- Logging: every action recorded, in a place you can read.
- Maintenance: who fixes it when your systems change, response times, and the monthly cost.
- An exit: how you take it over or move it if you stop working together. With us, you own the source code from the start.
Questions to ask before hiring
- Can you show an agent you built working, not slides?
- Will you test on our real documents or messages before we commit to the full build?
- Which of our systems have you connected to before, and how: API, database, exports or screens?
- What does the model see, and where does that data go?
- What happens when the agent is unsure?
- How will we know it is working after launch?
- What will it cost per month to run at our volume, including model usage?
Warning signs
- A promise of full automation with no human approval step.
- No test on your own data before a large contract.
- Accuracy figures without saying on which data they were measured.
- A quote that skips running costs: model usage, hosting and maintenance.
- A builder who cannot explain where your data is stored.
A sensible way to start
Pick one job that repeats daily, such as supplier invoices or WhatsApp orders. Ask two or three candidates for a pilot on a sample of your real cases, compare the results and how each team works, then commit to the full build with the one that did best.
SynthesisLogic is a team that builds AI agents in code, connected directly to your systems, and can run them on your own servers. We work remotely and start the same way: one job, tested on your real cases.
Questions
How much does it cost to hire someone to build an AI agent?
It depends on the number of systems, the messiness of the input and the hosting. Our projects start at US$1,000. Ask any builder for the build cost and the monthly running cost separately, for your volume.
Should the agent be built in code or on a no-code platform?
No-code is fine for simple flows. For ERP work, your own servers, approvals and real volume, code is faster, cheaper to run and easier to secure; our code vs no-code page compares them.
How long does a first agent take?
A focused first job usually takes weeks, not months, when the systems have APIs and the team has real cases to test on.
Can we hire you if we are outside your country?
Yes. We work remotely with companies in other countries and have no local offices.
