CompleteLine vs Allo

CompleteLine vs Allo: a new phone system, or an AI on the number you have

Allo is a modern business phone system for teams: per-seat numbers, calling, texting, CRM sync, with missed-call text-back and AI features. CompleteLine sits on your existing business number and does one job: turn every missed call into a booked job.

Two different products, honestly compared

Short answer: if you want to replace your phone system and give each person their own business line, Allo is a strong, inexpensive option. If you want to keep your phone setup exactly as it is and have AI follow up and book every missed call, CompleteLine does that without a switch.

Allo’s missed-call text-back sends an automatic reply. CompleteLine’s text starts a conversation: the AI answers questions from your business profile, books the appointment, and later asks for a review.

Pricing

Allo’s published pricing (as of October 2026) is per seat: Solo $15/mo, Business $45/mo and Ultra $120/mo (less billed yearly), plus a $24 one-time carrier registration for texting, with a 7-day free trial and no contract. Its AI receptionist is an add-on. CompleteLine Core is $249/mo plus a one-time $500 setup, with 1,000 texts and the AI included; Pro is $499/mo and adds the AI phone receptionist.

When Allo is the better choice

  • You want a new phone system with a line for each person on your team.
  • Your team is at a desk and can reply to texts themselves; you mainly need the automatic first text.
  • CRM sync with HubSpot, Salesforce or Pipedrive matters to you.
  • Budget is tight and per-seat pricing from $15 fits.

When CompleteLine is the better choice

  • You do not want to change phone systems. CompleteLine works with the number and phone you already have.
  • Nobody is free to reply when a call is missed, because you are on a roof or under a sink. The AI holds the conversation and books the job for you.
  • You want review requests and website chat handled too, at one price per business, not per seat.

Common questions

Isn’t Allo much cheaper?

Per seat, yes. Allo starts at $15 a month and CompleteLine Core is $249. They are different purchases: Allo replaces your phone system and leaves the follow-up conversation to your team, while CompleteLine leaves your phones alone and has the AI do the follow-up and booking. If someone on your team can always reply quickly, Allo may be all you need.

Do I have to port my number to use CompleteLine?

No. You dial a short call-forwarding code once, and your calls reach CompleteLine. Your number and carrier stay the same, and you can turn forwarding off the same way.

Try the difference on your own phone

Once your texting is approved, miss a call and watch CompleteLine text back in about 5 seconds and hold the conversation. From $249/mo plus a one-time $500 setup, month to month, 30-day money-back guarantee.
