ChatGPT Connector Coming soon

Billyou in ChatGPT.
Just ask.

Add Billyou as a ChatGPT connector, authorize one organization, and ask conversationally about invoices, payments, and reports. Billyou remains the source of truth; ChatGPT receives only the data needed for your answer.

How it works

Four steps. Set it up once.

01

Add Billyou as a connector

From ChatGPT (on plans that support connectors), add Billyou. You're redirected to the authorization page. Setup happens once.

02

Authorize one organization

Sign in with your Billyou account. The connector requests access to the organization you choose, via OAuth 2.0 with PKCE. No global access.

03

Ask in plain English (or Romanian)

Ask ChatGPT for clients with overdue payments, this month's report, or details about a specific invoice. Answers use real Billyou data.

04

Verify at the source

ChatGPT can summarize or reformat in ways that introduce errors. For any number that goes into a report, audit, or filing, verify directly in the Billyou dashboard or in SPV.

What you can ask

Concrete prompts, real answers from your Billyou account.

Prompt

Who are my clients with the most unpaid invoices?

How ChatGPT answers

ChatGPT calls the unpaid-invoices tool, groups by client, and returns the top list with total outstanding per client.

Prompt

Generate a summary for April for my internal report.

How ChatGPT answers

ChatGPT pulls the income/expense report for April, formats it as report text, and proposes a layout you can paste in.

Prompt

Find me the invoice for Acme Solutions from March.

How ChatGPT answers

ChatGPT calls the invoice-search tool with client and month filters and returns the invoice with serial, total, and SPV status.

Prompt

What's my average days-to-payment for recurring clients?

How ChatGPT answers

ChatGPT lists invoices with payment dates, computes the gap from issue date, and returns the average per recurring client.

Prompt

Export September's issued invoices for Saga.

How ChatGPT answers

ChatGPT calls the Saga export tool for September 1-30 and hands you the XML file, ready for your accountant. It covers issued invoices; expenses export from the app.

How it's built

Built on Model Context Protocol

Same open standard as the Claude connector. Specific tools (list invoices, find client, SPV status), not raw database access. ChatGPT calls only what the prompt requires.

Per-organization isolation

Each connection binds ChatGPT to a single Billyou organization at the moment of authorization. For a second company, authorize the connector again with that company's credentials.

OpenAI's policies apply

How data is handled after it reaches ChatGPT, including training and retention, depends on your OpenAI plan (Free, Plus, Team, Enterprise, API) and your account settings. On API, Team, and Enterprise plans, OpenAI states that customer data is not used for training by default. Check OpenAI's official privacy policy for the exact terms.

Every action, logged internally

We log every call internally: tool name, duration and outcome, with sensitive request data removed before storage. Records are kept for 90 days, then deleted automatically. Disconnecting does not delete them sooner.

Questions about the ChatGPT connector

No. ChatGPT calls specific tools and only receives the data needed for your prompt. Asking about invoices returns invoice fields. Without an expense question, expenses don't come along. The connector doesn't expose a full database mirror.
It depends on your OpenAI plan and your ChatGPT account settings. On API, Team, and Enterprise plans, OpenAI states that customer data is not used for training by default. On consumer plans (Free, Plus), there are settings you can review in your account. The official policy is OpenAI's. Billyou only sends data to ChatGPT when you prompt for it and does not control what OpenAI does with the data afterward.
The connector enforces scope at the OAuth level, bound to a single organization. The token cannot be used to query another company. Circumvention attempts are blocked by the MCP server and are a breach of these Terms.
Not at launch. The connector is read-only. Write capabilities will come in future versions: opt-in per organization, gated behind a paid-tier flag, with mandatory in-assistant confirmation for any destructive operation.
Two points. In ChatGPT, remove the Billyou connector from settings; the OAuth token is invalidated immediately. In Billyou (Settings, Active Sessions, MCP), revoke the session at the source. After revocation, ChatGPT must be re-authorized to make any further calls.
Billyou is built together with AxACont, an accounting firm with over 25 years of experience. The technology is built by developers; what data makes sense to expose to AI assistants, and under what conditions, is validated by accountants who file with ANAF every day. More at axacont.ro.

Your data, in ChatGPT.
With the lines an accountant would draw.

Read-only at launch. Every action logged internally. Strict single-org isolation.
