01The real objection, taken seriously
A real reply on a small business forum put the tension plainly: we really should just have a salary employee doing these tasks, AI costs too much. That objection deserves an honest answer, not a dismissal. A part-time hire in Romania costs a fixed monthly amount whether the phone rings ten times or a hundred, and comes with training time, sick days and turnover. An AI assistant scales with volume and never calls in sick, but it also cannot notice that a regular customer sounds upset today, or make a judgment call about waiving a fee for someone who has been loyal for years. Both are real costs, just different shapes of cost.
- A part-time employee costs a fixed monthly amount regardless of actual call volume
- An AI assistant scales with volume but cannot make a judgment call on a relationship
- Training time, sick days and turnover are real costs an AI assistant does not have
- Neither option is automatically cheaper, the shape of the work decides
02Where the line actually sits
The honest test is whether the business can write down what a correct answer looks like for every case the role handles. A receptionist confirming a booking, answering opening hours, or taking a name and number for a callback is following a script whether a person or an AI runs it. A receptionist who also decides which walk-in gets squeezed in during a busy afternoon, or who calms down a client who has been mistreated by another business, is doing something no script covers yet. PROOF48's own AI assistant page states this directly: it is not a good fit where every client situation needs a human judgment call, and that is not modesty, it is the actual boundary.
- If a correct answer can be written down for every case, the role can be scripted, by a person or an AI
- Judgment calls on relationships, exceptions and escalations still need a person
- PROOF48 refuses builds it can see failing from day one rather than overselling the fit
- The AI assistant handles volume, a person still handles the exceptions it flags
Automation that removed a step, not a person
Rotiseria Baba Novac's ordering system sends a Resend confirmation email the moment a Stripe payment clears, with the pickup slot attached, without anyone in the kitchen retyping an order into an inbox. It is not an AI assistant deciding anything, it is a fixed rule running automatically, but it shows the same principle: automate the repeatable step, keep a person on the parts that still need one.

Is an AI assistant always cheaper than an employee?
Not always. At low volume, a part-time hire and an AI assistant can cost about the same once setup and monitoring are counted. The AI assistant tends to win as volume grows, because the fixed cost of the person does not shrink on a quiet week.
Can the two work together instead of replacing each other?
Yes, and that is the usual setup. The assistant handles the repeatable volume and hands off anything unclear to a person, so the hire spends time on the calls that actually need a human rather than repeating the same answer all day.
Where PROOF48 fits
An AI assistant replaces the part of a role that can be written down as a script, not the part that needs judgment. PROOF48's AUTOMATE plan, at 2,997 EUR a month, is built for the first kind, and we say plainly when a build needs a person instead.
