The verdict in three sentences
A B2B matching platform connecting companies with technical contractors in Singapore (HVAC, electrical, IT) costs 80,000 to 200,000 SGD with a local agency, while Kolonell builds a V1 for 4,000,000 to 7,000,000 FCFA (about 8,800 to 15,400 SGD) with verified profiles, quote requests and ratings. Escrow payment (funds held until the job is validated) lifts the Kolonell budget to 7,000,000 to 15,000,000 FCFA, but it is what makes an 8 to 15% commission actually collectable. The real risk is not technical: it is liquidity, meaning enough reliable contractors in a district before you acquire clients.
Two business models, two budgets
In Singapore, many B2B service referrals still happen through personal networks, WhatsApp groups and generic directories. A platform captures value in two ways: a subscription paid by contractors to receive leads, or a commission on each job paid online. The choice shapes the architecture, and therefore the price.
| Criterion | Listings + subscription model | Commission + escrow model |
|---|---|---|
| Typical revenue | 50 to 150 SGD per contractor per month | 8 to 15% of the job value |
| Online payment | Subscription only (cards, PayNow) | Every job, with payout to the contractor |
| Bypass risk | Low, the contractor already pays | High if the added value is weak |
| Local agency budget | 80,000 to 120,000 SGD | 130,000 to 200,000 SGD |
| Kolonell budget | 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR) | 7,000,000 to 15,000,000 FCFA (10,670 to 22,870 EUR) |
| Time to launch | 8 to 12 weeks | 14 to 22 weeks |
| Fit to start | Yes, to validate demand | After 300 to 500 jobs a month |
Most serious projects start with the first model, measure demand for six months, then switch on escrow for categories where the average ticket exceeds 1,000 SGD (cold room maintenance, network cabling, electrical installation).
What a useful V1 contains, and what to postpone
| Feature | Estimated effort | Version |
|---|---|---|
| Contractor sign-up with documents (ACRA registration, insurance, licences) | 6 to 9 days | V1 |
| Manual profile validation by your team | 3 to 5 days | V1 |
| Multi-contractor quote request (3 replies maximum) | 8 to 12 days | V1 |
| Verified ratings and reviews after the job | 4 to 6 days | V1 |
| SMS and WhatsApp notifications | 4 to 7 days | V1 |
| Escrow payment with Stripe Connect and PayNow, with payouts | 15 to 25 days | V2 |
| Dispute management and arbitration | 8 to 12 days | V2 |
| Contractor mobile app (PWA) | 10 to 15 days | V2 |
On compliance, the platform collects personal data: Singapore's PDPA requires clear consent, a data protection officer and secure handling of identity documents. Hosting with encrypted documents and an access log costs 150 to 400 SGD a month depending on volume.
Mini case study
Illustrative example: Serge, a founder in Singapore, targets 120 technical contractors and 400 client SMEs across the central and eastern business districts.
- Phase 1 (subscription model): Kolonell V1 at 5,500,000 FCFA (about 12,000 SGD). 80 contractors subscribing at 100 SGD a month bring in 8,000 SGD a month. Hosting, SMS and Standard maintenance (75,000 FCFA, about 165 SGD) cost about 700 SGD a month. Monthly margin: 7,300 SGD, payback in about 2 months.
- Phase 2 (escrow): an extra 5,000,000 FCFA (about 11,000 SGD). 350 jobs a month at an 800 SGD average ticket and a 10% commission generate 28,000 SGD a month, minus about 3% card and payout fees (8,400 SGD).
The total investment of 10,500,000 FCFA stays within the range of a complex app and can be spread over two financial years.

FAQ
How much does a B2B matching platform cost in Singapore in 2026?
Local agencies quote 80,000 to 200,000 SGD. At Kolonell, a V1 with verified profiles and quotes costs 4,000,000 to 7,000,000 FCFA; with escrow and dispute management, 7,000,000 to 15,000,000 FCFA.
Which commission rate should we apply?
Between 8 and 15% depending on the category. High-value jobs (industrial refrigeration, networking) bear 8 to 10%, small interventions 12 to 15%.
How do we stop clients and contractors from dealing directly?
By offering value direct contact does not: payment guarantee, verified reviews, compliant invoicing. Hiding phone numbers until confirmation reduces bypass by 30 to 50% as an order of magnitude.
Which payment methods should we integrate?
Cards and PayNow cover most B2B payments in Singapore, with fees of about 1 to 3.5%. Bank transfer completes the setup for large accounts.
How long does it take to launch?
8 to 12 weeks for the V1, then 6 to 10 weeks to add escrow once demand is validated.
