ESBringing AI into your business: on your own with ChatGPT, a freelancer, an agency or a big consulting firm?
Updated October 27, 2026 · NouCodi
In short: if you just want your team to write and summarize faster, start on your own with ChatGPT or Claude on business accounts. If you want a specific process to stop being done by hand, a freelancer works when you already know what to build; a specialized agency, when you first need to find where the savings are; and a big consulting firm, when the project is corporate and has the budget for it.
The four options at a glance
| On your own | Freelancer | Specialized agency | Big consulting firm | |
|---|---|---|---|---|
| Entry cost | Licenses (≈ $20 per person per month) | Per project or hour | Diagnosis + project | High, long projects |
| Who decides what to automate | You | You | Together, with data | Together, with data |
| Measures savings before investing | No | Rarely | Should, ask | Yes |
| Reviews security and data | Up to you | Sometimes | Should, ask | Yes |
| Best fit | Small teams getting started | A well-defined task | SMBs with repetitive processes | Large enterprises |
1. On your own with ChatGPT or Claude
The cheapest and fastest way to start: drafting, summarizing, translating and brainstorming. The limit comes when you want a process to run on its own, because that means connecting software, testing with real cases and maintaining it. Essential: use business accounts and set written rules on which data can go in.
2. A freelancer
Good value when you know exactly what you want built, such as "create invoices from Stripe automatically." The risk is automating the wrong task or a step that shouldn't exist, and depending on one person for maintenance.
3. A specialized agency
Makes sense when you're not sure where to start: it first measures how your team works, calculates the savings of each improvement, then implements what pays off most. Always ask to see the savings math before a quote, for a security review, and for accounts to stay in your name.
4. A big consulting firm
Brings methodology, large teams and backing for transformation projects at large enterprises. For a small or midsize business it is usually out of proportion in price and timeline.
Five questions to choose
- Do I already know which process I want to improve and what it costs me today?
- Who will maintain it when something changes?
- Will they show me the calculated savings before I pay for the project?
- Do the accounts and data stay in my name?
- Have they done something similar in my industry, and can they show it?
