The plan buys the software. Who pays for the messages?
How the two are put together
Agency platforms are usually licensed. You pay for the login, and the texts and the minutes ride a second meter behind it. GoHighLevel publishes plans at $97, $297, and $497 a month, and its support portal describes phone, email, and AI usage as separate charges drawn from a prepaid agency wallet that tops itself up from the card on file. Rebilling that usage to your clients unlocks on the $297 and $497 plans. For an agency, that is not a flaw. That meter is the margin.
Drop Cowboy is built the other way around. We run our own phone layer, so the volume you send is part of the plan you already bought. Messaging plans start at $125 a month. The complete platform starts at $224. One line on the card, one number to budget against, and nothing to top up in the middle of a send.
Already have a carrier? Bring it. Bring your own carrier works across the products, with messages as low as $0.006 each. You will need an existing Twilio account or a compatible SIP provider to do it. GoHighLevel supports connecting your own Twilio account too, so if you go that route, run the per-message math on both.
