A visitor asks about an order, or a caller asks for a quote. The chat agent or the voice agent answers from your own catalog and policies, asks the qualifying questions you wrote, and books the appointment. Anything it should not decide goes to a person with the transcript attached.
The lead lands in Automate: the CRM record, the follow-up sequence, the booking, the two-way text thread. That is the self-serve product, priced on the page and billed at Stripe.
When the lead becomes an order, the order, the stock, the invoice, and the books live in Cloud ERP, managed ERPNext on Frappe Cloud. One ledger, no re-keying, and a month-end close that does not depend on a spreadsheet.
You do not need all four on day one. Read the explainers, pick the line that fixes today's problem, and add the next one when it earns its place. Implementation services cover the migration, the build, and the training.
