Receptionists by the minute, or a secretary at a flat rate.

Your callers expect a human voice, and that matters to your brand

Nexa is the reasonable pick.

If a human on the line is the point, not just a way to get calls answered, buy the human service. Go in with a written quote and your real call volume modeled, so the per-minute bill doesn't surprise you.

Your call volume swings hard — slow winters, slammed summers

KaiCalls.

Per-minute billing means your busiest, best months are also your priciest. With a flat plan, July costs what February costs, and every one of those extra calls still gets answered, booked, and texted back.

You keep missing calls at night and on weekends

KaiCalls.

Nexa answers 24/7 too, billed by the minute. With KaiCalls the 9pm call rings your cell first. If you don't pick up, Kai books it into tomorrow's calendar and texts the caller a confirmation. You wake up to a summary, with no after-hours charge.

You want a service that also places outbound calls for you

Either could work.

Nexa lists inbound and outbound sales on its 300 and 500 minute plans, with people dialing. KaiCalls does outbound follow-up and callbacks too, from your own number. Decide on the same fork as everything else: a person billed by the minute, or a secretary at a flat rate.

Nexa is a virtual receptionist service. Trained receptionists answer your calls, set appointments, qualify leads and pass on messages. It also sells a "Voice + AI" service. KaiCalls is your business phone line with a secretary built in. Your cell rings first. If you can’t pick up, Kai answers, books into Google Calendar, texts the caller back and texts you a summary.

For many of the same jobs, yes: answering, booking, taking details and follow-up. The trade is the voice. With Nexa’s live plans a person picks up. With KaiCalls your cell rings first, then Kai answers, at a flat monthly price.

When you want a person on the line, or you need client intake and outbound sales calls handled by trained receptionists. Nexa answers 24/7 on every plan.

When you want a predictable bill and you answer most calls yourself. Your cell rings first. Kai picks up when you can’t, at 2am or during the lunch rush, and the call ends with a booked appointment, a text to the caller and a summary on your phone.

As of November 4, 2026, Nexa does not publish prices. Its plans are sold by minutes (100, 300 or 500), extra minutes are charged at your base rate, and there is a setup fee. KaiCalls is $10/month flat for Kai Backup with ~20 Kai-answered calls/mo, your business number included, and no per-minute or per-call charges on any plan.

It means the bill grows with your call volume. That's not a trick. It's how per-minute pricing works. Your busiest months are also your most expensive. Flat pricing works the other way: more calls don't grow the bill.

Three things: (1) Get a written quote and model it against your real monthly call minutes. (2) Ask about the setup fee and the cancellation terms. (3) Check whether appointments go straight into your calendar and whether callers get texted back, or whether messages still land on your plate.
