The verdict in three sentences
An event planner steering 3 to 8 million FCFA per wedding cannot afford a forgotten deposit or a venue booked twice. A purpose-built app that unites timeline, vendor book, budget vs actual and mobile-money deposits removes those blind spots and saves 8 to 14 admin hours per event. At an MVP of 1.2-2.5M FCFA, the tool pays for itself within 3 to 5 managed weddings.
Why spreadsheets and WhatsApp no longer cut it
A beginner planner runs on a notebook, one WhatsApp group per wedding and a budget spreadsheet. That holds up to 2-3 simultaneous events. Beyond that, information scatters: the caterer's deposit sits in one chat, the decor delivery date in another thread, the photographer's balance in the planner's head. The result: forgotten follow-ups, vendors paid late, and the constant stress that something will slip through the cracks.
A purpose-built app doesn't replace the planner's talent — it removes the mental load. Each event becomes a single dashboard where you see at a glance what is booked, paid, pending and overdue.
| Module | Concrete benefit | Indicative cost (MVP) | Dev time |
|---|---|---|---|
| Event timeline (D-90 to D+7) | Zero forgotten task, automatic alerts | Base included | 1 week |
| Vendor book + contracts | Contacts, rates, availability centralized | 250,000-400,000 FCFA | 1 week |
| Budget vs actual tracking | Margin protected, overruns visible | 300,000-500,000 FCFA | 1-2 weeks |
| Mobile-money deposits (Wave/OM) | Automatic collection and reminders | 400,000-700,000 FCFA | 2 weeks |
| Client portal (approval, photos) | Fewer back-and-forths, pro image | 300,000-500,000 FCFA | 1-2 weeks |
The game-changing module: budget vs actual
A wedding planner's margin runs around 10 to 15% of the total budget. On a 5M FCFA wedding, that's 500,000 to 750,000 FCFA. A single uncontrolled overrun (caterer billing 300,000 more, forgotten chair rental) can halve that margin. The budget vs actual module shows the live gap between planned and paid, line by line.
| Line item | Planned budget | Actual committed | Variance |
|---|---|---|---|
| Venue + catering | 2,500,000 | 2,650,000 | +150,000 |
| Decor + flowers | 800,000 | 780,000 | -20,000 |
| Photo + video | 700,000 | 700,000 | 0 |
| Entertainment + DJ | 500,000 | 550,000 | +50,000 |
| Misc + contingency | 500,000 | 420,000 | -80,000 |
| Total | 5,000,000 | 5,100,000 | +100,000 |
Seeing that +100,000 FCFA live lets you renegotiate or adjust before the margin is eaten.
Mini case study
Fatou, a wedding planner in Dakar, handles 3 weddings a month in high season, average budget 4.5M FCFA. Her margin: 12%, or 540,000 FCFA per wedding. Before the app, she spent about 12 admin hours per event (follow-ups, spreadsheets, deposit tracking) and had two double-bookings in one year, each settled with a 150,000 FCFA goodwill gesture.
With a purpose-built app at 1.8M FCFA, she saves 10 hours per wedding. Across 3 weddings/month — 30 freed hours — she can take a 4th wedding some months: +540,000 FCFA of margin in those months. By eliminating double-bookings, she saves roughly 300,000 FCFA/year. The app pays for itself within 3 to 4 months of high season.

FAQ
How much does an event-planner app cost?
A working MVP (timeline, vendor book, budget, mobile-money deposits) sits between 1.2 and 2.5M FCFA depending on modules. Advanced features (client portal, dedicated mobile app) are added later in stages.
How long to build the app?
An MVP typically ships in 5 to 8 weeks. You start with the timeline and vendor book, then add budget and deposits once the core is validated.
Can I collect client deposits directly in the app?
Yes. The Wave and Orange Money integration lets you send a payment link, collect the deposit and trigger an automatic reminder for the balance. Each payment updates the budget in real time.
Is it suitable for an event agency, not just weddings?
Absolutely. The same structure serves seminars, conferences, birthdays or launches. You just adapt the timeline templates and vendor categories.
What if my connection is unstable on the big day?
The app can run offline to view the timeline and vendor book, then sync as soon as the network returns. Essential for poorly covered venues.
