Sign in and choose
Sign in to Billingz. By default it can only read. Tick more only for what you want it to do, then confirm.
Steps may change in Claude’s and ChatGPT’s own settings.
You decide.
By default it can only read. Switch the connection to Ask me in Billingz, and every action that issues, sends, reminds or records waits under Needs you until you approve it there. Drafts do not wait.
Disconnect any time.
Open Account, then Connected AI tools, and choose Disconnect. From that moment Billingz refuses every call. Remove it in your assistant as well, so you are sure.
What it is
Billingz, inside your assistant.
Add Billingz to Claude or ChatGPT once. Then you tell it in plain words, and it works with your own numbers.
- It reads only, until you allow more.
- It finalizes, sends, reminds and records a payment when you confirm in the chat.
- It never moves money and never touches your bank details.
- What it can do follows your plan. There is no extra price.
Your assistant asks you before it acts. Billingz cannot see the chat, so that depends on your assistant. To keep the last word in Billingz, switch the connection to Ask me in Billingz.

Questions
Short answers.
Does it move my money?
No. Billingz never moves money, and nothing in this connection does. Recording a payment you received only records it. A bill to pay waits under Needs you, and you pay it in your own bank.
Can it send an invoice on its own?
Not if your assistant asks you first. It shows you what goes to whom, and you confirm in the chat. If you told your assistant to always allow, it can send without asking. To keep the last word in Billingz, switch the connection to Ask me in Billingz.
What happens to my data?
What the assistant asks for is sent to its provider and handled under its terms. Billingz does not choose your assistant and is not its processor. How this works: Privacy Policy, section 2d.
Does it cost extra?
No. There is no separate price. What it can do follows your plan.
Can it be wrong?
Yes. Check what it shows you before you confirm. Billingz gives signals, not financial, tax or legal advice.
Use Billingz in the assistant you already use. The decisions stay with you.
