The causes are billing, currency or verification, a service window counted from the wrong side, templates, a handoff with no transcript, a bad phone number, and a workflow that reports success when nothing was delivered. Delivery status shows each failure before a customer does. https://samambai.com/blog/does-llms-txt-work/ https://samambai.com/blog/does-llms-txt-work/ Sat, 03 Oct 2026 12:00:00 GMT llms.txt does not get a business cited by ChatGPT, Gemini, or Google's AI. Google says Search ignores the file. OpenAI tells sites to allow OAI-SearchBot and the published IP ranges. The file still works as an index for coding agents and docs. https://samambai.com/blog/how-much-does-ai-automation-cost/ https://samambai.com/blog/how-much-does-ai-automation-cost/ Sat, 03 Oct 2026 12:00:00 GMT AI automation in 2026 is our fee plus the vendor bills in your name. The public table is a sprint at US$ 1,200, a project from US$ 3,000, and a partnership from US$ 900 a month. WhatsApp, the model, and n8n are not inside those numbers. https://samambai.com/blog/lovable-app-production-checklist/ https://samambai.com/blog/lovable-app-production-checklist/ Sat, 03 Oct 2026 12:00:00 GMT Publish puts a Lovable app on a public URL. Production means a second user can sign in, see only their own rows, and come back tomorrow with the service still up. This is the checklist we run before we call it ready. https://samambai.com/blog/meet-samambai/ https://samambai.com/blog/meet-samambai/ Sat, 03 Oct 2026 12:00:00 GMT samambai is an engineering studio that puts AI into production, with USD prices published before the first call. We grew out of PowerAds, we are based in São Paulo, and we already work with companies in São Paulo, New York, Madrid, and Tel Aviv. https://samambai.com/blog/n8n-self-hosted-vs-cloud/ https://samambai.com/blog/n8n-self-hosted-vs-cloud/ Sat, 03 Oct 2026 12:00:00 GMT As of 2 October 2026, n8n Cloud Starter is €20 a month on the annual plan, and self-hosted Community is a €0 license plus a server. Pick Cloud or a server based on who operates the machine, how many executions you burn, and what the license lets you do for a client. https://samambai.com/blog/what-gets-a-business-cited-by-ai/ https://samambai.com/blog/what-gets-a-business-cited-by-ai/ Sat, 03 Oct 2026 12:00:00 GMT A business gets cited when the page is in that engine's index, answers the question with a price and a date, is corroborated by someone else, and stays current. An llms.txt file, special schema, and fabricated mentions do not clear those gates. https://samambai.com/blog/whatsapp-ai-agent-off-the-shelf-or-custom/ https://samambai.com/blog/whatsapp-ai-agent-off-the-shelf-or-custom/ Sat, 03 Oct 2026 12:00:00 GMT An off-the-shelf WhatsApp tool is enough when your system is already on its connector list and the rule fits the product. A custom agent is worth it when the reply has to read your calendar, CRM, or ERP and hand the thread to a person.
