These four options solve the missed-call problem in different ways. Ruby is a live human receptionist service billed by the minute. Smith.ai sells live agents billed by the call and, separately, an AI receptionist. Goodcall is AI only, billed per agent per month by the number of unique customers who speak to it. FlashCrafter is not a standalone answering service: it is a done-for-you growth platform (website, CRM, local SEO and a set of AI agents) in which a Voice Answering Service AI answers missed calls and captures the request.
Price is hard to compare because each vendor counts something different: calls, minutes or unique customers. Published entry prices run from $79 a month per agent for Goodcall's Starter plan, to $250 for Ruby's 50 minutes, to $300 for Smith.ai's 30 live-agent calls. Smith.ai also has an AI tier that starts at $0 for 25 calls. FlashCrafter publishes no price. Reviewers of Smith.ai, Ruby and Goodcall all describe billing surprises, so the headline plan price is a floor, not a forecast.
Choose Ruby if you want live people answering and prefer minutes-based plans with a 21-day money-back window. Choose Smith.ai if you want live agents or a pay-per-call AI tier and use Housecall Pro or ServiceTitan, which Smith.ai documents integrations for. Choose Goodcall if you want the lowest published monthly price and are comfortable with an AI-only agent. Choose FlashCrafter if you want a new website, CRM and local SEO along with call answering from one provider, and you are willing to evaluate a vendor with no published price and no independent reviews. If you only need someone or something to pick up the phone, one of the other three is the more direct fit. If you already answer nearly every call, measure your own missed calls before paying for any of them: the commonly quoted missed-call statistics are published mostly by vendors and are unaudited.
