The verdict in three sentences
For a purchasing group of 220 hospitality members and 60 suppliers, a B2B marketplace only pays off if it captures a real share of purchasing: aim for at least USD 2 million in annual trading volume at a 3% commission. A SaaS platform lets you launch in 2 to 3 months and test the model, while a custom platform becomes cheaper beyond 3 years and as soon as business rules (member-specific negotiated prices, year-end rebates, grouped deliveries) get complex. The decision rests on the break-even volume, not on the development price.
What a purchasing group marketplace must handle
A hospitality purchasing group is not a standard online store. Prices are not public, each member has its own terms, and the group is often paid through a supplier commission and annual rebates. The platform must reflect that model without breaking it.
| Business need | Standard SaaS marketplace | Custom marketplace |
|---|---|---|
| Supplier catalogues with member-specific prices | Partial, often by customer group | Price grids by member, brand, emirate |
| Multi-supplier order in a single cart | Yes | Yes, with automatic purchase order split |
| Commission by supplier (2 to 6%) | Single rate or by category | Rate by supplier, product family, volume tier |
| Year-end rebates | Not handled | Automatic calculation and supplier statements |
| 30 or 60-day terms, bank transfer, post-dated cheques | Limited | Terms per member, due-date tracking |
| UAE VAT-compliant invoicing (5%) | Export to rework | Compliant invoices and commission statements |
| Mobile app for head chefs | Responsive web interface | Quick ordering, favourite lists, scanning |
2026 cost: SaaS or custom
The amounts below are 2026 market estimates for the UAE, in USD (1 USD is about 3.67 AED). They are not Kolonell prices.
| Item | SaaS marketplace | Custom marketplace |
|---|---|---|
| Setup and configuration | USD 8,000-20,000 | Included in the project |
| Development | None | USD 60,000-150,000 |
| Time to launch | 2 to 3 months | 5 to 7 months |
| Subscription | EUR 1,000-5,000 per month, about USD 1,100-5,400 | None |
| Hosting, maintenance, enhancements | Partly included | USD 1,500-3,500 per month |
| Provider transaction fees | Sometimes 0.5 to 1% of volume | 0% excluding bank fees |
| Code and data ownership | Vendor | Purchasing group |
Over 3 years, a SaaS at about USD 3,250 per month with USD 15,000 setup costs around USD 132,000. A custom platform at USD 100,000 with USD 2,500 monthly maintenance costs USD 190,000. The gap narrows sharply if the SaaS also takes a percentage of volume.
The commission model: 2 to 6% by product family
In B2B, the commission must stay below the margin a supplier is willing to give up. Fresh produce suppliers rarely accept more than 2 to 3%, while equipment and consumables can bear 5 to 6%.
| Product family | Typical 2026 commission | Typical share of hospitality purchasing |
|---|---|---|
| Fresh produce (meat, fish, fruit and vegetables) | 2 to 3% | 35 to 45% |
| Dry goods and beverages | 3 to 4% | 20 to 25% |
| Hygiene and cleaning products | 4 to 5% | 8 to 12% |
| Tableware, linen, consumables | 5 to 6% | 8 to 10% |
| Small kitchen equipment | 5 to 6% | 5 to 8% |
| Services (maintenance, cleaning) | 4 to 6% or subscription | 5 to 10% |
A 3% weighted average rate is realistic for a hospitality group. A supplier subscription of USD 100 to 300 per month can top up the commission without putting off small suppliers.
Mini case study
Omar, director of a hospitality purchasing group in Dubai, wants to cover the cost of a custom platform: USD 100,000 development and USD 2,500 monthly maintenance, or USD 190,000 over 3 years, about USD 63,300 per year.

At a 3% average commission, he needs 63,300 / 0.03 = USD 2.11 million in annual volume. His 220 members buy on average USD 4,000 a month from listed suppliers. If 20% of that goes through the platform, or USD 800 per member per month, volume reaches 220 x 800 x 12 = USD 2.11 million. Break-even comes with one in five purchases made online.
If adoption stalls at 10%, SaaS is the better first-year choice while usage is proven. Omar can negotiate a data export clause to move to custom later.
FAQ
How many suppliers do we need at launch?
Launching with 15 to 20 suppliers covering 70% of routine purchases is enough. Onboarding all 60 at once adds 1 to 2 months of catalogue loading.
Should the supplier or the member pay the commission?
In purchasing groups it is almost always the supplier, at 2 to 6%. Charging members slows adoption, except as an annual membership fee, often USD 300 to 1,000.
Do we need to collect payments on the platform?
Not necessarily. Many groups let suppliers invoice and collect, then bill the commission monthly. Collecting yourself secures the commission but requires treasury management and a UAE bank or payment provider agreement.
What is a realistic timeline for a custom launch?
Allow 5 to 7 months: 1 month of scoping, 3 to 4 months of development and 1 month of pilot with 20 to 30 members.
How do we get members to order online?
Effective levers are slightly better online prices, around 1 to 2%, recurring order lists and year-end rebate tracking visible to each member.
