If you're comparing Smith.ai and ZilchWork, or searching for a Smith.ai alternative, you're probably weighing one real question: do you want a better answering service, or do you want the work after "hello" handled too? These are different products at different prices, and one of them is sometimes the wrong buy. Here's the honest version, including where Smith.ai beats us.

What is Smith.ai genuinely good at?
Smith.ai owns the human-backup niche, and that's a real advantage. Some callers, in some businesses, want a human voice on the line, and Smith.ai's hybrid plan is the credible way to offer one without hiring your own staff. We don't have staffed humans on standby; if that's a hard requirement for your callers, Smith.ai is the stronger pick and you can stop reading here.
The trade-offs are the ones the category shares: per-plan limits and per-call economics can climb as your volume grows, and at the end of the call the lead is handed to you rather than worked for you. The message arrives; the follow-up, the booking discipline, and the CRM entry are still your evening job.
What does ZilchWork do differently?
ZilchWork isn't a receptionist; it's a front office. Our AI, Anna, answers every call 24/7, calls brand-new web leads back in seconds, qualifies them, pitches your actual offer, books the job, asks for the sale, texts a secure checkout link, and takes payment live on the call for unregulated sales. In regulated industries she books and preps, and licensed humans finalize. Every interaction logs itself; the CRM fills itself in. We build it, run it, and maintain it.
The speed piece matters more than most buyers expect. The Oldroyd lead-response research, covered by Harvard Business Review, found five-minute responders qualify leads at roughly 21 times the rate of thirty-minute responders, and Velocify's Ultimate Contact Strategy measured a 391% lift when the callback lands within a minute. An answering service, however good, receives calls; it doesn't chase your inbound leads inside those windows.
Why is ZilchWork 3 to 10 times the price?
Because the two products are priced against different things. Smith.ai competes with voicemail and a part-time receptionist. ZilchWork is priced against payroll: on our math a staffed front office runs roughly $20,500 a month, between a receptionist around $5,000, a sales team and closer around $10,000, back-office data entry around $5,000, and about $500 in tools. If nobody in your business needs that work done, don't pay us for it. If you're doing it yourself at 10 p.m., $997 flat is the cheap option.
Which should you choose?
- Choose Smith.ai if your callers genuinely need a human option, your call volume is modest, and you have the time (or staff) to work every message it sends you.
- Choose ZilchWork if the messages are piling up unworked, leads go cold before you call back, or you're paying for answering and still losing jobs. Answering was never your real problem; follow-through was.
- Budget tight and just starting? There are $49 tools that take messages politely. Run your numbers in the lost-lead calculator first, and see the full field in our alternatives comparison.
How do you test both before deciding?
Call both. Every serious vendor has a demo. Ours picks up any hour at 518-629-1415, or talk to Anna in the browser. Try to break her; edge cases are where these products separate. Switching to us costs $99 for a three-day trial (credited to your first month), the $999 setup is waived until August 31, we migrate your data, and the guarantee is: live in 7 days or your first month is free.

FAQ
Is ZilchWork a good Smith.ai alternative?
If you're leaving Smith.ai because per-call costs climbed or leads still slip after the message, yes; that gap is our entire product. If you're leaving because you want cheaper answering, look at flat-rate message-takers instead.
Does ZilchWork have human backup like Smith.ai?
Not staffed humans on standby; that's Smith.ai's genuine edge. Anna routes calls to your team when a human is needed, and in regulated industries licensed humans finalize every sale.
Why is ZilchWork so much more expensive than Smith.ai?
Different jobs. Smith.ai answers and hands you the lead. ZilchWork answers, calls new leads back in seconds, qualifies, books, asks for the sale, takes payment on unregulated sales, and fills in the CRM itself. You pay against payroll saved, not against other software.
Can ZilchWork migrate my data from Smith.ai?
Yes. Migration is part of the done-for-you setup, and the $999 setup fee is waived through August 31.
Can I keep my current phone number if I switch?
Yes. Keeping your number is standard in this category, ours included.
