The verdict in three sentences
A wedding in Thies or Saint-Louis mobilizes 15 to 25 vendors over 60 to 120 days, and a single failure breaks the logistics chain. An app that centralizes electronically signed digital contracts, Wave deposits and the budget P&L cuts the vendor cancellation rate from 18% to 3%. On an average budget of 2,500,000 to 4,500,000 FCFA, the overspend alert at D-30 protects the planner's margin.
Centralizing 15 to 25 vendors without missing anything
Caterer, sound, decoration, griot, photographer, transport, venue rental, pastry: each vendor has its contract, deposit and balance. Managing this on WhatsApp and notebooks creates costly oversights. The app sets the schedule and responsibilities.
| Vendor item | 2026 avg budget (FCFA) | Typical deposit | Balance due |
|---|---|---|---|
| Caterer (200 covers) | 1,200,000 | 50% | D-3 |
| Venue/tent rental | 600,000 | 50% | D-7 |
| Sound & DJ | 350,000 | 40% | D-1 |
| Floral decoration | 400,000 | 50% | D-2 |
| Photo/video | 450,000 | 30% | Delivery |
| Griot & entertainment | 250,000 | 50% | Day of |
| Guest transport | 300,000 | 40% | D-1 |
*Minimum deposit 75,000 FCFA per vendor, Thies/Saint-Louis 2026 order of magnitude.*
Wave deposits and real-time P&L
The core of the system: pay 30 to 50% at booking via Wave, track balances and watch the P&L update with every expense. The electronically signed digital contract commits the vendor and reduces last-minute drop-outs.
| Indicator | Without app | With app + Wave contracts |
|---|---|---|
| Vendor cancellation rate | 18% | 3% |
| Deposit tracking | notebook | live dashboard |
| P&L visibility | end of event | real time |
| Budget overspend alert | none | automatic D-30 |
| Balance disputes | frequent | timestamped signed contract |
| Coordination time/week | 12h | 4h |
The D-30 overspend alert leaves time to renegotiate or cut an item before the margin disappears.
Mini case study
Aida, a wedding planner in Saint-Louis, runs a 3,800,000 FCFA wedding with 21 vendors. Last season, 2 vendors canceled at D-10 (18% failure), generating 320,000 FCFA in urgent replacement costs. With digital contracts and the 50% Wave deposit locking commitment, she dropped to 3% cancellation. The D-30 alert also flagged a 180,000 FCFA caterer overspend, renegotiated in time. Her planner net margin (15%) rose from 410,000 to 570,000 FCFA on this wedding alone.
