Dachs Limousines - Premium chauffeur fleet (Barcelona)
We built FleetBytes so the traffic office stops fighting the ERP. It imports the day's work, answers questions in plain language and reaches drivers over WhatsApp.

Where we came in
Dachs Limousines has run private chauffeurs in Barcelona since 1940. Daily dispatch came out of an industry ERP that is solid for invoicing and history, but slow for the day itself. Exports arrived with junk characters that someone cleaned by hand, flight delays were checked one by one, and finding out whether a driver had arrived meant calling them.
A layer on top, not a replacement
Replacing the ERP of a company that invoices every day is the fastest way to break it. So FleetBytes leans on it instead. You upload the day's export, the system cleans it, normalises dates and times and lands it structured in PostgreSQL in seconds. From there the office works against a modern dashboard rather than an endless table.
Asking instead of searching
On top of that data sits a chat that turns the question into a query. Ask what a driver is doing at two in the afternoon, or how many VIP transfers there are at the airport tomorrow, and the answer comes back formatted. Flight numbers are checked against a tracking API, and the dashboard flags a service when the flight is late, so the driver is not waiting hours in the terminal.
Drivers without phone calls
Drivers get the job over WhatsApp, with buttons to confirm arrival at the pickup point, passenger on board and job finished. They install nothing. One tap and the status changes on the traffic office's screen.
Pricing and proformas
The pricing engine encodes the company's real rate card: overtime, the night surcharge and per diems all come out of the hours worked. It reproduces their proformas to the cent, with regression tests on every change, because in invoicing one euro too many is a call from the client.
Where it stands
It is in production and in daily use. It installs on a phone as an app without going through any store. Next on the list are the carbon report built from total kilometres and vehicle type, and a rush-hour warning when too many jobs land in the same window.
