The verdict in three sentences
A B2B fresh produce marketplace only works if it solves two problems at once: reliable supply for hotels and restaurants, and cash flow for growers. With an 8 to 12% commission on an average order of about $650, the model breaks even around 1,500 to 2,000 orders a month, provided net-15 hotel terms and weekly grower payouts are under control. Kolonell builds this kind of platform as a custom project between 2,500,000 and 15,000,000+ FCFA (3,810 to 22,870+ EUR) depending on complexity.
The market: demanding buyers, scattered growers
Miami Beach and Brickell hotels, Wynwood and Coral Gables restaurants, corporate and school cafeterias buy produce, seafood, poultry and dairy daily. Today, chefs and purchasing managers juggle broadline distributors and a handful of specialty suppliers, with inconsistent quality and little visibility on local sourcing. On the other side, growers in the Redland and Homestead agricultural area sell through intermediaries that capture much of the value.
A marketplace with 60 growers and 150 professional buyers structures this flow: a daily catalogue, prices known the evening before, refrigerated delivery before 9 am and a single invoice.
| Model parameter (2026 order of magnitude) | Conservative case | Target case |
|---|---|---|
| Active buyers | 80 | 150 |
| Orders per buyer per month | 10 | 14 |
| Average order | $550 | $650 |
| Monthly GMV | $440,000 | $1,365,000 |
| Platform commission | 8% | 12% |
| Monthly commission revenue | $35,200 | $163,800 |
| Refrigerated delivery cost per order | $45 | $35 |
Must-have features
- Daily catalogue updated by each grower from a phone: available quantities, prices, photos.
- Order by 6 pm for next-morning delivery, grouped into refrigerated routes.
- Quality check on receipt: the buyer approves or flags an item, triggering an automatic credit note.
- Net-15 terms for approved hotels, with credit limits, and instant card or ACH payment for others.
- Automatic split: the commission is retained, the grower's share is credited to their balance.
- Weekly grower payouts by ACH with a detailed statement.
- Dashboards: sales per grower, dispute rate, hotel receivables, margin per route.
- Food safety records: lot tracking and traceability, increasingly expected by hotel groups under FSMA rules.
| Kolonell project level | Kolonell budget | Typical scope |
|---|---|---|
| Simple | 2,500,000 to 4,000,000 FCFA (3,810 to 6,100 EUR) | multi-grower catalogue, ordering, online payment, flat commission |
| Medium | 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR) | + net-15 terms, automatic split, weekly payouts, disputes |
| Complex | 7,000,000 to 15,000,000+ FCFA (10,670 to 22,870+ EUR) | + route planning, driver app, demand forecasting, multi-city |
| Maintenance | 35,000 / 75,000 / 120,000 FCFA per month | fixes, backups, payout monitoring |
| Accounting integration, native mobile app | quote-based | depends on tools and timeline |
For comparison, a Miami agency typically quotes $60,000 to $200,000 for a comparable marketplace in 2026 (order of magnitude), and subscription marketplace software runs about $300 to $1,500 a month, with weak support for buyer credit and quality credit notes.
The cash flow trap
Net-15 hotel terms combined with weekly grower payouts create a gap: the platform advances money for about 8 days on average. On $1 million of monthly GMV sold on terms, that is roughly $270,000 of working capital. Three levers: reserve terms for hotels with a payment history, offer 1% off for immediate payment, and set up invoice factoring with a lender once volume is proven.
Mini case study
Maria and Jordan, co-founders in Miami, start with 60 growers and 90 buyers. By month six they process 1,400 orders at $600, $840,000 of GMV.

- Average 10% commission: $84,000 monthly revenue.
- Logistics: 1,400 × $40 = $56,000.
- Team of 4: $24,000. Payment fees at 1.5% of GMV: $12,600.
- Monthly result: $84,000 − $92,600 = −$8,600.
At 1,400 orders, the Miami model still loses money because delivery is expensive. Raising the average order to $700 through minimum orders and dense routes ($30 per drop) turns it positive: $98,000 revenue against $42,000 logistics, $24,000 team and $14,700 fees, a $17,300 monthly margin. Platform cost, at 6,500,000 FCFA for a medium build, is minor next to route density.
FAQ
What commission should we start with?
Start around 8% to attract growers, then move to 10 to 12% once you deliver visible services: cold chain logistics, guaranteed payment, weekly payouts.
How are rejected items handled?
The buyer flags the item with a photo within 2 hours, a credit note is generated automatically and deducted from that grower's payout. Aim for a dispute rate under 3%.
Do we need a native mobile app?
Not at launch. A PWA works for growers and buyers. A native app makes sense above 500 active users and is quote-based.
How do we limit hotel non-payment?
Set a credit limit per hotel, for example $10,000, block automatically beyond 15 days overdue, and require upfront payment from new accounts for their first 2 months.
How long until launch?
Allow 12 to 16 weeks for a medium-complexity platform, then a 2-month pilot with 20 buyers before opening widely.
