How to avoid vehicle booking conflicts at work

Two people booking the same car at the same time almost never happens through carelessness: it happens because the tool being used doesn't prevent it. Here's why, and how to make it impossible rather than just rare.

The problem comes from the tool, not the people

On a shared spreadsheet, nothing stops two people from editing the same cell at the same time: each sees the version they opened, not the other person's changes in progress. The conflict is only discovered afterward, when both show up at the parking lot.

A check "on display" isn't enough

Many tools only check availability when displaying the schedule, not when saving the booking. In between, someone else may have booked the same slot: the check comes too late.

The only reliable protection: a database-level constraint

The structural way to prevent a conflict is to make it impossible to record, not just unlikely on screen. A database exclusion constraint rejects the insertion of a second booking that overlaps an existing one on the same vehicle, even if both requests arrive at the same millisecond. That's the mechanism Flotalyo uses: if a conflict is technically impossible to record, it can no longer happen, no matter how many people book at the same time.

Frequently asked questions

Is a simple warning message enough to avoid conflicts?

No: an on-screen warning can always be ignored or bypassed (two open tabs, a missed refresh). Only a constraint at the point of saving truly prevents the duplicate.

Does this slow down booking for the user?

No: the check is instant and invisible to the person booking. They only notice a difference in the rare case where the vehicle was just taken in the meantime — in which case another available vehicle is automatically suggested.
