Time a régie spends on an incomplete dossier before discarding it.

Like many, I watched talented friends get rejected on apartments well within reach — simply because their dossier wasn't ready in time, or didn't match the codes of Romandy property managers. Dossio was born to close that gap: a tool that lets you compete with a dossier as strong as the best-prepared applicants. No bullshit. No inflation. Swiss.
