One request runs through two procedures, and each sends its own queries.
A bakery registers a stall at the weekly market through the citizen service portal. The registration under the Trade Regulation Act (Gewerbeordnung) lands with the trade licensing office, the market licence application with the market administration, and both offices ask for the same documents separately.
1requestA stall at the weekly market, reported informally through the portal.
2proceduresBusiness registration and market licensing run side by side under their own reference numbers.
2requests for documentsEach office writes to request the documents it needs.
4calls to the officeThe applicant phones both offices twice each, because he assumes it is a single procedure.
Both procedures appear with their document lists in the first reply. The four phone calls become unnecessary, and the trade licensing office sees 45% fewer queries.
The 45% is a benchmark from the profile, not a result from your trade licensing office. Your own figure is hidden in the phone calls of the first week after market day.
