Websites that take the booking, send the invoice and follow up the lead.

Petronix builds websites for service businesses and rental owners, then connects the payments and automation behind them. Enquiries get an answer in minutes, even when you are out on a job.

A US-registered LLC. One point of contact from first call to launch.

One enquiry, handled
  1. 09:02Enquiry arrives from the website"Two-bedroom deep clean, this Friday?"
  2. 09:02Reply sent with price and open slots
  3. 09:03Lead saved. Owner pinged on WhatsApp
  4. 09:17Slot booked, deposit paid by card
  5. 09:17Invoice and what-to-expect email sent
  6. Thu 16:00Reminder sent the day before

An example of the flow we build. Your steps will be your own.

Most websites stop at the contact form. The work starts there.

A good-looking site still loses customers if nobody answers quickly. This is what changes when the site and the follow-up are built as one thing.

  1. Visit
  2. Enquiry
  3. Reply
  4. Booking
  5. Payment
  6. Follow-up
Website only Website with the system behind it
An enquiry waits in the inbox until you finish work.It gets a reply with a price and a next step within minutes.
A booking takes a chain of messages.Customers pick a slot and pay a deposit on the site.
Invoices are written by hand at night.Invoices and receipts go out when the payment lands.
Follow-up depends on someone remembering.Reminders and follow-ups run on a schedule.
Nobody knows which enquiries became work.Every lead is tracked from first message to paid job.

I had a great experience working with Petros on my website! He was professional, responsive, creative, and really took the time to understand my vision. He was easy to communicate with and made the process smooth from start to finish. I’m very happy with how everything came together and would definitely recommend Petros to anyone looking for a talented and reliable web designer!

I started Petronix after meeting too many owners who had paid for a website and got nothing back from it. A site should earn its place. So we build the part people see, and the part that answers, invoices and follows up after they get in touch.
