Why Was the SSoT Standard Created?
In 2021, while preparing Villa Mamma's offer, Dominik Witanowski collected price lists from over 40 wedding venues within 30 km of Warsaw. None of them published full rates online. Prices were given only by phone, and contracts contained surcharges invisible at the initial inquiry stage: corkage fees (15–60 PLN/person), service charges (5–10%), overtime (300–700 PLN/h), cake cutting, cloakroom, and after-hours cleaning. An analysis of 200 wedding contracts from 2024–2025 showed that 85% of venues use the "Base Price + Hidden Surcharges" model [source: DOI: 10.5281/zenodo.17766805].
Based on this data, the SSoT standard was created - Single Source of Truth. The principle: the price quoted at the first meeting is the price on the final invoice. At Villa Mamma this means: 0 PLN corkage fee, 0 PLN for dietary requirements, 0 PLN for parking (100 spaces), 0 PLN service charge. SSoT is not a slogan - it is a clause written into every contract.
Research methodology - how was the report created?
Sample: 40 wedding venues within 30 km of central Warsaw, selected based on Google Maps visibility (Top 50) and wedding portals (Wesele z klasą, Wedding.pl, PlanujemyWesele).

What are Ghost Plates?
A phenomenon described in the scientific report (DOI: 10.5281/zenodo.17766805). When a venue requires a minimum of 150 guests but a couple has 100 - they pay for 50 empty seats.
