The Whoza.ai alternative with a flat monthly fee
Whoza.ai answers your calls with an AI voice and charges per booked job on top of its monthly fee. TextBack Pro replies by SMS for one flat price, however many jobs you book.

What a good month costs you
Whoza.ai's pricing rewards you for missing calls and charges you for winning them. Here's what that looks like in practice.
| Scenario | Whoza.ai (Starter) | TextBack Pro |
|---|---|---|
| Quiet month, 8 jobs booked | £59/mo (within the 10 included) | £47/mo |
| Good month, 20 jobs booked | £59 + (10 × £4.50) = £104/mo | £47/mo |
| Great month, 35 jobs booked | £59 + (25 × £4.50) = £171.50/mo, or upgrade to Growth at £125+/mo | £97/mo (Pro, 500 SMS included) |
| Cost of your best month | Highest when business is best | Predictable regardless of performance |

Which one is right for you?
Both are built for UK trades. The right choice depends on whether you want a voice or a text, and how you want to be billed.
- You want callers to hear a voice rather than receive a text
- You're comfortable with a bill that rises as you book more jobs
- You want built-in competitor analysis and review automation bundled in
- You're happy trying a brand-new company with no published reviews yet
- You want the same monthly cost whether business is quiet or booming
- You'd rather your customers get a text they can reply to in their own time
- You don't want to track per-job charges alongside your subscription
- You want a 14-day trial with no card required
Whoza.ai and TextBack Pro: voice vs text, per-job vs flat fee
Whoza.ai is a Scotland-based AI receptionist built for UK trades, with named AI voice agents (Katie and Mark) that answer your phone in a UK accent of your choosing and pass the qualified lead to your WhatsApp. It's a well-built product and it has attracted UK press coverage. The two things worth understanding before you compare it to TextBack Pro are the mechanism and the pricing model.
Voice vs SMS
Whoza.ai answers the call itself, with a synthetic voice, and holds a spoken conversation before handing off the lead. TextBack Pro does not answer the call: it lets it go to voicemail as normal, then sends the caller an SMS within seconds. Some callers prefer speaking to something, even an AI. Others find an unexpected AI voice on the other end of a call unsettling, and would rather receive a text they can reply to when it suits them. Neither approach is objectively better, but they are genuinely different experiences for your customer.
The pricing model is the bigger difference
Whoza.ai's pricing includes a set number of "booked jobs" per plan, then charges £2.25 to £4.50 for every additional job booked that month. In practice, this means your bill is lowest in your quietest months and highest in your best ones, the opposite of what most tradespeople want from a fixed monthly tool. TextBack Pro charges one flat fee per plan, with no per-job charge, so a great month costs exactly the same as a quiet one.
Track record
Whoza.ai's Trustpilot profile was claimed in July 2026 and had no published customer reviews at the time of writing, despite genuine UK press coverage of the company. That's not necessarily a red flag for a new company, but it does mean there's little independent evidence yet of how the product performs at scale. If proven customer feedback matters to you before committing, that's worth factoring in alongside the product comparison above.
