Hello! Yes, the listing is still active. I'm looking at availability for a viewing this week — morning or afternoon, and will you be alone or accompanied?

One client asks for a quote, another for an appointment — while an important request waits for a reply.

The SENTARA difference

Before SENTARA.
With SENTARA.

The same customer message. Two very different levels of reply.

Message received
"Hi, do you have availability tomorrow and what's the rate?"
Without SENTARA
Improvised reply
"Hi, yeah maybe. Depends what you want."
✕Vague and unconvincing
✕No next step
✕Unstructured
With SENTARA
Prepared reply
"Hello, thank you for your message. We can check tomorrow's availability. Could you tell me which service you're interested in so I can give you the right time slot and rate?"
✓Clear and professional
✓Next step defined
✓Reassuring and conversion-oriented
Context understood
The intent of the message is analyzed before the reply
Structured reply
Adapted tone, industry vocabulary, coherent message
Clear next step
Every reply naturally moves the conversation forward

Your requests, everywhere

All your requests. One place to organize them.

  • Hi, do you have a slot on Friday?
  • Could you prepare a quote for me?

“Hi, can you give me a quote to replace my brake pads?”

Reply prepared by SENTARA

Hello, happy to help. To put together an accurate quote for your brakes, could you tell me the model, year and engine of your vehicle? As soon as I have them, I'll prepare a detailed estimate for you.

You review. You approve. You send.

The time you save: a few seconds to review and approve, where an improvised reply often takes long minutes of thought.

The result

Fewer repetitive tasks. More time for your business.
