| Which plan to pick | Take the 14-day trial, which needs no card. Solo is a bargain if you sell alone and follow up by hand. Growth is where Close earns its price, because that's where automated follow-ups, the power dialer and Chloe in workflows start. Budget a little extra each month for call minutes. | If you already have a lead list, Growth is all you need to start. If you need leads too, compare Growth plus Growth Credits with the Starter bundle, which adds the AI Sales Agent for about the same money. Agencies sending for clients usually end up on Hypergrowth or Light Speed. | Start on pay as you go with the free credits, build one agent for your most common call and test it on your own phone. Talk to sales only once you run thousands of minutes a month. |
