Is ChatGPT good for business? What changes when AI knows your ERP

The short answer is yes. ChatGPT works for business, and it’s good at a lot of things: writing a tough email, summarizing a contract, analyzing a spreadsheet, researching a new supplier. If nobody on your team uses AI yet, it’s a good place to start.

The question I find more useful is a different one: which part of the company’s work does it handle, and which part stays with you?

What ChatGPT offers businesses

According to OpenAI’s official ChatGPT Business and pricing pages, checked on September 26, 2026, the Business plan is for companies with 2 or more users. The team works in a workspace with shared company context and plugins, either ready-made or built for the company’s systems. There are admin controls, SSO and multi-factor authentication, and Business data isn’t used to train the models.

With ChatGPT Work, it takes a goal, gathers the context, makes a plan, carries it out and calls you in when it needs your input or approval. It’s a strong general-purpose AI for almost any area of the business.

Where the running around continues

Take a common case at a fictional company, Lume Casa. A customer, Ana Paula R., asks for the third time where order #1842 is. Bia, in customer service, opens Bling, finds the order, searches the purchasing Gmail for Têxtil Norte’s promise, asks Marina on WhatsApp whether it has shipped and only then asks ChatGPT for a polite reply.

The reply comes out great. But notice: Bia was the one who figured out what was going on. The AI wrote. The running around stayed with her.

An AI that doesn’t know the company depends on someone to explain the company to it.

What changes when AI knows the ERP

When AI reads the company’s systems, the same question becomes a different conversation:

• The question already comes with the answer. The AI reads the order, the stock and the supplier’s email, and answers with the source of each piece of information.
• Nobody pastes in context. What’s in the ERP, the inbox and the task board is already within its reach.
• What’s stuck shows up before the complaint does. An open order becomes a task with a plan, without waiting for someone to remember.
• It solves, not just answers. It chases the supplier, updates the date in the ERP and lets the customer know, then tells you what it did.
• It says what it didn’t see. If the information isn’t in any system, it tells you, instead of making up a date.

You can get close to this with ChatGPT Business, because it accepts plugins built for the company’s systems. But someone has to build or set up that connection, decide what the AI looks at and when, and keep it all running. In a small business, who’s going to take care of that?

Three questions to help you decide

• Is the problem writing and analyzing, or chasing things down? For the first, a general AI does the job. For the second, the AI needs to know your systems.
• Who’s going to connect the AI to the ERP and maintain that connection? If nobody, the running around of finding and gathering stays with the team.
• What does the AI do on its own? Agree on what it handles directly and what goes through you, like payments and anything sensitive.

You can use both

You don’t have to pick a side. ChatGPT can take the writing and analysis, and a right hand that knows the ERP takes on the running around of operations. That’s what Will does. In Ana Paula’s case, it finds the order in Bling, reads Têxtil Norte’s promise in Gmail, answers the customer with the new date and lets Bia know: "I replied to Ana Paula. The linen arrives Thursday, and I’ll let you know when the order ships." Nobody had to explain the company to it.

And if your company uses a different ERP? Will works with Bling, Omie, Tiny, TOTVS, SAP and other ERPs, with the banks through Open Finance (regulated by Brazil’s Central Bank), with your store, your CRM and the marketplaces. And if a system has a login, Will uses that too. The side-by-side comparison is in Will vs ChatGPT. And if you’d like to talk about your case, get in touch.
