The verdict in three sentences
A B2B agri inputs marketplace connecting 40 suppliers of fertilizer and seeds to farm buyers and agri cooperatives across Singapore and its regional supply network can launch as an MVP for 2,500,000 to 7,000,000 FCFA (about 3,810 to 10,670 EUR) depending on the Kolonell development level chosen, in 3 to 4 months. The business model rests on a 5 to 10% commission, collected automatically through split payments between the platform and the supplier via PayNow or a marketplace payment provider. The main risk is not technical: it is having enough active suppliers and up-to-date stock before the buying season opens.
What the MVP must do, and nothing more
The founder often wants everything at once: mobile app, delivery tracking, input credit, buyer scoring. For an MVP that must prove demand over one season, the useful scope is shorter.
| Feature | MVP (simple level) | Full version (medium level) |
|---|---|---|
| Multi-supplier catalogue | Yes, product pages priced per 50 kg bag | Yes, with volume-based tiered pricing |
| Buyer accounts | Yes, one account per buyer company | Multi-user with manager approval |
| Payment | PayNow with automatic split | PayNow, cards, bank transfer and trade credit |
| Platform commission | Single configurable rate | Rate per category (fertilizer, seeds, crop protection) |
| Supplier dashboard | Orders and payouts | Stock, analytics, invoices |
| Logistics | Pickup at warehouse or supplier-managed delivery | Freight calculation by zone (Singapore, Johor, Riau) |
| Kolonell cost (custom application) | 2,500,000 to 4,000,000 FCFA (3,810 to 6,100 EUR) | 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR) |
The simple level is enough for a first season with 40 suppliers and 100 to 200 buyers. The medium level becomes relevant once buyers ask for internal approvals and several payment methods are required.
The commission model: simulate before coding
Agri inputs carry thin margins for suppliers, often 8 to 15% on fertilizer. A commission set too high pushes suppliers back to direct sales. Simulation on a typical order of 30 bags of NPK fertilizer at 50 SGD per bag, or 1,500 SGD (indicative 2026 market price):
| Commission | Platform revenue per order | Supplier keeps | Estimated payment fees (1 to 1.5%) | Net platform revenue |
|---|---|---|---|---|
| 5% | 75 SGD | 1,425 SGD | 15 to 22.50 SGD | 52.50 to 60 SGD |
| 7% | 105 SGD | 1,395 SGD | 15 to 22.50 SGD | 82.50 to 90 SGD |
| 10% | 150 SGD | 1,350 SGD | 15 to 22.50 SGD | 127.50 to 135 SGD |
| 5% fertilizer, 10% certified seeds | Variable | Variable | Same | Common balance in practice |
Certified seeds and crop protection products can bear 8 to 10%, bulk fertilizer closer to 5%. A per-category rate, included in the medium level, avoids losing large fertilizer suppliers.
Automatic split payments
The technical flow works like this: the buyer pays the full order, the platform receives the funds on its merchant account, records the commission, then triggers the payout to the supplier after delivery is confirmed. This escrow period, from 48 hours to 7 days, protects the buyer and reduces disputes.
Points to watch: payment limits on instant transfers (a large buyer order can exceed daily limits, hence the value of split payments or a bank transfer option), the payout API which must be enabled by the provider, and traceability for the platform's accounting and GST obligations.

Wei Ling, founder of an agri inputs platform in Singapore, targets 150 buyers and 40 suppliers over the season. If each buyer places 3 orders of 1,500 SGD on average, volume reaches 675,000 SGD. With an average 7% commission and 1.25% payment fees, net revenue is about 38,800 SGD. An MVP at 3,500,000 FCFA (about 5,340 EUR) plus 6 months of Standard maintenance at 75,000 FCFA a month (450,000 FCFA in total, about 690 EUR) is covered several times over by first-season revenue. Even at only 50 buyers, net revenue (about 12,900 SGD) still covers the investment.
FAQ
How long does it take to launch the MVP?
Allow 3 to 4 months, including 3 weeks to onboard suppliers and load the catalogue. Launch at least 6 weeks before the buying season so buyers have time to order.
What commission should we start with?
5% on fertilizer and 8 to 10% on certified seeds is a common starting point. You can offer 0% to the first 10 suppliers for 3 months to seed the catalogue.
Is a single payment method enough?
PayNow covers most local B2B payments, but regional buyers often prefer bank transfer or cards. The simple level starts with one method, and the medium level adds others for about 10 to 15% of the budget.
How are quality disputes handled?
Payment stays in escrow 48 hours to 7 days after delivery. If the buyer reports a problem with a photo, the payout is suspended and arbitration happens in the back office.
Do we need a mobile app for the MVP?
No, a lightweight web application optimised for mobile is enough. It weighs under 1 MB on first load and avoids app store publishing costs.
