The workflow was designed for a small guiding operation in the Pyrenees that runs six-week summer and winter seasons. The main constraint was offline access: most bookings come from mountain huts with no mobile signal. We needed a system that could sync later, not in real time.

We started by mapping the actual booking path. A client calls or sends a message from a hut phone. The guide writes down name, dates, and group size on paper. Later, at a village with internet, that data is entered into a shared spreadsheet. The problem was double entries and lost notes when two guides handled the same week.

The approach was to build a lightweight form that works offline in a browser cache. The guide fills it on a phone or tablet, and the entry stays local until a connection appears. When the device finds Wi‑Fi, it pushes the data to a central log. No real‑time dashboard, no notifications — just a reliable queue.

We tested the workflow during the 2023 summer season. Three guides used it for 47 bookings across five huts. The main tradeoff was that the guide had to remember to open the form and sync before leaving the village. Two entries were delayed by a day because the device ran out of battery. No data was lost.

The result is a process that fits the actual conditions of mountain guiding: low tech, high reliability, and a clear paper trail. The same approach can be adapted for gear rental logs or hut reservation sheets.
