Try asking

“Which sales invoices from March are still unpaid?”
The AI lists invoices in that date range filtered by state, with client and totals.
“Create a draft invoice for Talleres Ruiz: 8 hours of maintenance at 45 euros plus IVA.”
It finds the client and the IVA rate and creates a draft invoice with one line. The draft stays provisional.
“Email invoice F-240 to the client.”
It sends the invoice by email to the address you give, with an optional subject and message.

What your AI can do

Invoices and payments

Create, update and email sales invoices, get PDFs, and record payments received against your bank accounts.

Estimates and bills

Create, update and email estimates, and list, read and record supplier bills.

Contacts and products

Search, create and update clients, suppliers and products, and list IVA rates and payment methods.

Questions

What can the AI do in FacturaDirecta?

The AI can read contacts, sales invoices and their PDFs, estimates, supplier bills, products, bank accounts, payment methods and IVA rates. It can create and update contacts, products, invoices and estimates, email invoices and estimates, record payments on invoices and record supplier bills.

Does the AI see my FacturaDirecta API key?

No. Your FacturaDirecta credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start read-only. Sending invoices and estimates emails your clients, a final invoice gets a legal number, and recording a payment books it in your accounts. These tools can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own FacturaDirecta account.

Can the AI create a final invoice?

Yes, if you allow it. The AI can create an invoice as a draft, which stays provisional, or as a final invoice, which gets a legal number and cannot be freely deleted. Final invoices may also be locked by Spanish invoicing rules. Working with drafts and requiring approval for invoice creation keeps you in control.
