What changes at a repair shop with an AI agent?
What changes is who answers first: the message no longer waits for you and gets answered right away. These are four everyday repair shop situations before and after the CertuAI agent.
TodayA queue of price questions while you solder a board
With CertuAIQuote by model and fault answered right away, from your price list
TodayCustomer keeps calling to ask about the device
With CertuAIStatus answered on its own and automatic notice when it's ready
Today"I'll think about it" and the customer is gone for good

TodayWarranty and turnaround explained a hundred times a week
With CertuAIWarranty rules and turnaround times answered the same way every time
What does a conversation handled by the AI look like?
Example conversation
Repair shop AI agent
Customer: How much is a Samsung A54 screen?
AI agent: The Samsung A54 screen is your price, with a turnaround of your turnaround.
Customer: My phone fell in water. Can it be fixed?
AI agent: Tell me what it does now: won't turn on, black screen? I'll note the symptom and the history before the device arrives.
Which is better for repair shops: an AI agent or manual customer service?
The agent wins at repetitive tasks, and people keep winning at what takes judgment. With manual service, someone at the repair shop has to stop what they're doing; with the CertuAI agent the answer goes out on its own and you join the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| A queue of "how much is the screen?" during a repair | The bench stops with every reply, or the customer waits for an answer until night | Price list by model and fault answered right away, with turnaround time |
| "Is my device ready yet?" | Calls all day interrupting the board soldering | Stage answered on its own and automatic notice on completion |
| Warranty explanation | Repeated a hundred times a week, a different way each time | Term, coverage and what voids it answered the same way every time |
| Customer who asked for a price and said "I'll think about it" | Gone for good and nobody chases | Automatic follow-up days later, with the offer's expiry date |
| Device arriving with no context | Fault discovered at the counter, with the customer waiting | Symptom and history collected in the conversation before the device arrives |
