sight: bartenders need to mix drinks, not spreadsheets.
What We Learned
Industry Pain Points 73% of bartenders still use paper or basic Excel to generate quotes Average time to create a single quote: 3.5 hours 40% reported losing events due to unprofessional proposals Calculation errors cost bartenders an average of R$500 per month
User Behavior Mobile-first is essential: 80% create quotes on-the-go Visual customization matters: branded PDFs increase close rates by 35% Simplicity wins: users prefer a 3-click experience for core actions WhatsApp integration is critical for the Brazilian market
Technical Insights Supabase’s Row-Level Security was initially complex but became key to our data protection strategy React’s component architecture aligned perfectly with our modular design approach PDF generation posed challenges (we tested three libraries before landing on a stable solution) Real-time price calculations required careful and optimized state management
