| 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. | 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. | Ask for a trial first and check the data covers your market, especially outside the US. Copilot Advanced is where the AI and buying signals come in, which is most of the reason to pay ZoomInfo prices. Negotiate the renewal terms before you sign, and if your budget is under five figures, look at Apollo instead. |
