The Smith.ai alternative
without per-call math.
Smith.ai is a strong service — but per-call billing means a busy month is an expensive month. PhoneMachine answers your calls 24/7 on flat plans from $39/mo billed annually, with texting, booking, and call screening built in.
Smith.ai’s published live-receptionist Starter plan is $300/month for 30 calls, then $11.50 per call over 30; appointment booking is a $1.50/call add-on. PhoneMachine is a flat-rate full phone system — AI answering, two-way texting, and calendar booking from $39/month billed annually, with a personalized sample call available before its card-required trial.
WHY PEOPLE LOOK FOR AN ALTERNATIVE
Where Smith.ai costs you
more than money.
Per-call pricing punishes growth
On Smith.ai Starter, every call after the 30-call allowance is $11.50. Flat plans make monthly budgeting more predictable because a short call and a long call do not each consume the same billable call unit.
It’s an answering service, not your phone system
Smith.ai answers calls. You still need a business line, texting, and somewhere for the records to live. PhoneMachine is the whole stack: your number (ported or new), two-way SMS with AI replies, missed-call text-back, voicemail, fax, and a unified inbox.
Texting is the follow-up channel
PhoneMachine texts the caller a confirmation during the call, texts back missed calls instantly, and runs keyword auto-replies 24/7 — included, with guided 10DLC carrier registration.
