Field notes on AI-era growth, deliverability, voice, and messaging for developers and teams building on Orbit by Devotel.
Google Jibe and the GSMA-tier carriers activated per-message RCS billing on the verified-agent path in late 2025, making RCS cost like SMS premium on delivered traffic. This explainer covers what changed, what template mix does to the bill, and which tenant-owned controls decide what you actually pay.
A CPaaS vendor bills on one of three pricing models — usage-based per-event metering, a flat-rate platform subscription, or a revenue-share cut of traffic. This post runs the worked TCO equation for all three across three monthly message-volume bands and names the winner per band, with an illustrative-figures disclaimer.
An educational deep dive into every line on a voice AI agent's bill — speech-to-text, the language model, text-to-speech, and telephony — why each line moves independently, and the ROI discipline that separates a cost per minute you admire from a cost per resolved conversation you can defend. Builds on our AI voice agent pricing guide with the component-math and break-even frameworks applied end to end.
Video and RTC businesses bill on three pricing models — per-minute of room time, per-participant metering, and pure pay-as-you-go. This post runs the worked TCO arithmetic at three usage shapes with illustrative unit rates, and shows where an all-in-one pay-as-you-go account (Devotel Orbit) lands against each.
The four-bill problem (Programmable Voice + Messaging + SendGrid + Segment) asserted on /compare/twilio, walked through with arithmetic: a worked 50,000-message-month scenario priced on published rates, the hidden line items that ride on top, a footnoted TCO table, and an honest map of when the assembled Twilio stack still wins.
Meta has moved WhatsApp Business Platform billing from per-conversation to per-message, while widening free windows from API entry points. This explainer covers what changed, what costs less now, and which tenant-owned controls decide what you actually pay.
UCaaS bills per seat per month; CPaaS bills per message, minute, and API call. This post models both on a 20-agent mixed call/SMS/workflow profile, shows where the break-even sits, and explains when each billing model actually wins.
What an AI voice agent actually costs in 2026 — the four per-minute components (speech-to-text, the language model, text-to-speech, and telephony), why a single per-minute quote misleads, how the three pricing models compare, and a framework for calculating ROI against human-handled calls.
