Invoicing Software You Can Run from Claude or ChatGPT
SolidInvoice has a built-in MCP server, the open standard AI assistants use to work with your apps. Connect Claude, ChatGPT or Cursor and ask it to create an invoice, record a payment or chase what is overdue. It does the work, not just read your data. Included on Pro ($19/mo) and Business ($39/mo).
Free forever. No credit card required.
Your AI Can Do the Billing, Not Just Talk About It
Some invoicing connectors only let an AI assistant read your numbers. SolidInvoice lets it act: create the invoice, convert the quote, record the payment, send the reminder.
Typing the same client, rate and due date into a form every month is the slow part of invoicing. Say "bill Acme for 12 hours at my usual rate, due in 30 days" and the draft is waiting for your review.
Finding out who owes you means filters and exports. Ask "what is overdue more than two weeks?" and get the list, with totals, in the chat you already have open.
Handing an AI your books feels risky. You sign in, choose read-only or read and write access, and can revoke the connection at any time.
Everything You Need, Nothing You Don't
Create invoices and quotes
Draft invoices and quotes, clone last month's invoice, convert an accepted quote into an invoice, and set up recurring invoices, all from a sentence.
Record payments and send reminders
Tell the assistant a client paid by bank transfer and it records the payment. Ask it to nudge a late client and it sends the invoice reminder.
Answer billing questions
Outstanding and overdue totals, revenue by month, invoice status breakdowns and a summary per client, answered from your live data.
You control the access
OAuth sign-in with no API keys to copy. Read access is required, write access is your choice, and you can revoke a connected assistant instantly.

What to ask your assistant
Once connected, these requests work in Claude, ChatGPT or any MCP client. Most assistants show you each action and ask before they run it.
- 1
"Create an invoice for Acme for 12 hours of consulting at $120, due in 30 days."
The assistant looks up the client, adds the line, sets the due date and creates the invoice for you to review and send.
- 2
"Which invoices are overdue, and how much is outstanding in total?"
It lists overdue invoices with client, amount and days late, plus your total outstanding and total overdue.
- 3
"Acme paid invoice 1042 by bank transfer today."
It records the payment against the invoice, which marks it paid and stops any remaining reminders.
- 4
"Send a reminder for every invoice more than a week overdue."
It finds the matching invoices and sends each client a reminder with a link to pay.
- 5
"Turn the accepted website quote into an invoice."
It converts the quote to an invoice with all of its lines, ready to send.
- 6
"How much did I invoice each month this year?"
It pulls revenue by period from your account, so you can ask follow-up questions without opening a report.
