--- title: "CFDI 4.0 Invoicing Bot by Chat" description: "Issue CFDI invoices (Mexico’s e-invoice) by typing the sale in a chat: the bot assigns SAT codes, adds the taxes and returns stamped XML and PDF. Setup $2,500 MXN." canonical: "https://rigolco.com/en/invoicing-bot/" lang: "en" --- URL: https://rigolco.com/en/invoicing-bot/ Automated invoicing # Invoice from a chat: type what you sold, get your stamped CFDI. In Mexico, invoices are CFDIs: electronic invoices validated through the SAT, the federal tax authority. Our chat bot reads the sale as you type it in plain Spanish, assigns the SAT codes, calculates the taxes and sends back the stamped (timbrada) invoice as XML and PDF. No logging into the SAT portal, no code catalogs, no dictating to anyone. And if your customers ask you for invoices, we build them a portal to do it themselves. [ Book a call ](https://cal.com/ton-rigol-rojano-okaosp/30min) [See pricing](#pricing) The problem Invoicing today means logging into the portal, finding the client, wrestling with the product/service code, choosing a unit of measure, remembering whether it was PUE or PPD (paid in full or in installments) and hoping the stamping goes through. Get something wrong and you cancel and start over. Half an hour per invoice that nobody pays you for. The promise You describe the sale in the chat the way you’d tell a colleague, and seconds later you have the stamped CFDI with its XML and PDF. How invoicing works ## From the sale to the stamped invoice, step by step. No forms, no code catalogs to search, no tax portal. This is everything that happens between opening the chat and getting the invoice: you tap and type, the bot handles the SAT side. 1. 1 ### Pick the company that invoices If you invoice under more than one RFC, choose the issuer with one tap. Its tax regime and postal code are already set up. 2. 2 ### Pick the customer One you’ve invoiced before, the general public (it builds the global invoice) or a new customer you add right there. 3. 3 ### Type the sale in your own words The way you’d tell a colleague. The bot turns it into line items with their SAT product code, unit and taxes. 4. 4 ### Say how you get paid Paid now (PUE) or on credit (PPD), payment form and currency. On credit it sets form 99 on its own, as the SAT requires. 5. 5 ### Review the totals and tap Stamp VAT and withholdings calculated by law according to your regime and your customer’s. Anything off? You edit it in the same chat. 6. 6 ### The XML and the PDF land in the chat Stamped, with its tax folio. The number follows the series: if a stamp fails, the retry reuses it, no gaps. Invoiced on credit (PPD)? When your customer pays, the same bot issues the payment complement. Sample conversation and invoice with made-up data · not a real invoice. Self-invoicing portal ## And your customers invoice themselves. If you sell over the counter or online, we build a portal with your brand: your customer enters their ticket and tax details and downloads their CFDI on the spot. No more emails asking for invoices, no more typing them up by hand. - Your brand and your domain - XML and PDF downloaded on the spot - Connected to your invoicing Custom quote [Quote your portal ](https://cal.com/ton-rigol-rojano-okaosp/30min) ## What your bot includes Line items in natural language You type the sale the way you’d say it. The AI builds the line items and assigns each one a product code, a unit of measure and its taxes. Several issuing companies If you invoice under more than one RFC (Mexican tax ID), they all live in the same bot. Pick which one issues the invoice and you’re done. Global invoice Sales to the general public are grouped into a global invoice (factura global), at whatever frequency applies to you. Checks before stamping It checks the payment method and form (PUE/PPD), the tax details and, if you invoice in a foreign currency, the exchange rate. It warns you before stamping, not after. Sequential folio numbers, no gaps Every series is tracked. If a stamping attempt fails, the folio is neither lost nor duplicated: the bot picks the attempt back up. XML and PDF right away Both files arrive in the chat as soon as the invoice is stamped, and your history is always at hand when you need to look something up. What you need ## Your certificates and tax details. Nothing else. To get started we only need your SAT digital seal certificates (CSD) and your tax details. We set up everything else: the PAC (the SAT-authorized provider that stamps your invoices) is included in your plan, so there’s nothing to contract separately and no second platform to deal with. The bot runs on Telegram for now: it’s free and installs in a minute on a phone or computer. WhatsApp is on the roadmap, with no date yet. Investment ## Clear pricing. No surprises.

For now, yes. The bot runs on Telegram, which is free, works on phone and computer and installs in a minute. WhatsApp is on the roadmap, but there’s no date yet and we’d rather not promise it: we’ll let you know when it’s available. Do I need to know the SAT codes? No. You describe the sale in plain Spanish and the AI builds the line items with their product/service code, unit of measure and taxes. Before stamping, the bot shows you a summary and validates the tax details so you can review and confirm. What do I need to get started? Your SAT digital seal certificates (CSD) and your tax details. We provide the PAC (it’s included in your plan), so there’s nothing to contract separately. We handle the rest of the setup. What happens if stamping fails? The folio is neither lost nor duplicated: the bot tracks the series, picks the attempt back up and tells you the actual reason for the rejection in plain language, so you can fix it and stamp again without gaps in your numbering. Can I invoice for several companies? Yes. The same bot can issue invoices under several RFCs (Mexican tax IDs): you register each issuer with its certificates and series, and choose which one invoices each time. It’s standard practice in accounting firms and in groups with several legal entities. Can I pay for the year up front? Yes. Pay for twelve months up front and we bill you for eleven: one invoice at the start, non-refundable if you cancel early. It applies to the monthly fees in this page’s annual payment table, not to the setup. It’s optional: the monthly plan still has no minimum term. ## How many hours a month do you lose to invoicing? Tell us how you invoice today and we’ll tell you whether the bot is a good fit, and what it would take to get it running. [ Book a call ](https://cal.com/ton-rigol-rojano-okaosp/30min)
