The verdict in three sentences
For a consultant network or umbrella company placing more than 100 assignments a year, a custom matching platform costs between 50,000 and 90,000 EUR in Amsterdam in 2026 (40,000 to 70,000 EUR with a French or West African delivery team) and usually pays for itself in under 18 months. The main gain is staffing time, which drops from about 10 days to 3 days once profiles are filtered by skills, availability and day rate. A generic marketplace such as Malt or Toptal is still useful for sourcing, but it does not handle your contracts, your commission or your proprietary talent pool.
What an internal matching platform actually does
The core of the product is an engine that matches an assignment brief (skills, seniority, location, target day rate, start date) with the profiles in your pool. Around that engine sit application management, generation of assignment contracts, monthly timesheet tracking and commission calculation.
| Module | Function | Share of budget (2026 estimate) |
|---|---|---|
| Consultant profiles | Structured CV, rated skills, availability, day rate | 15% |
| Assignment briefs | Client input, needs, budget, on-site Amsterdam / remote | 10% |
| Matching engine | Score by skills, rate, availability, history | 25% |
| Contracts and e-signature | Assignment contract, umbrella agreement, e-sign | 15% |
| Timesheets and invoicing | Monthly entry, client approval, accounting export | 20% |
| Commission and reporting | 8-12% rate, margin per assignment, dashboard | 15% |
The matching engine does not need generative AI to work well. A weighted score (skills 50%, availability 25%, rate gap 15%, client history 10%) is enough for 800 profiles. Semantic CV search can be added in V2 for 6,000 to 10,000 EUR.
Budget, timeline and options: three scenarios
| Scenario | Scope | Budget (Amsterdam agency) | Timeline | Annual run cost |
|---|---|---|---|---|
| Internal MVP | Profiles, briefs, filter matching, PDF export | 50,000 EUR | 4 months | 5,500 EUR |
| Standard | MVP + generated contracts, e-signature, timesheets | 70,000 EUR | 4.5 months | 7,500 EUR |
| Full | Standard + client portal, advanced scoring, payroll API | 90,000 EUR | 5 months | 10,000 EUR |
| Malt / Toptal (subscription) | External sourcing, no umbrella contracts | 0 EUR build | Immediate | 10-20% commission taken |
| No-code (Bubble + Airtable) | Basic matching, limits beyond 300 profiles | 18,000 EUR | 2 months | 6,000 EUR |
Run cost covers EU hosting (GDPR), corrective maintenance, e-signature licences and security updates. The choice between Standard and Full mostly depends on the client portal: when clients post their own needs, it removes about 2 email exchanges per assignment.
Commission and profitability: the deciding calculation
| Indicator | Before platform | After platform |
|---|---|---|
| Average staffing time | 10 days | 3 days |
| Assignments placed per year | 150 | 170 (lost deals recovered) |
| Average day rate | 680 EUR | 680 EUR |
| Average commission | 10% | 10% |
| Account manager hours per assignment | 9 h | 3.5 h |
| Assignments lost for lack of a fast profile | 18% | 6% |
A 60-day assignment at a 680 EUR day rate generates 40,800 EUR of revenue, or 4,080 EUR of commission at 10%. Recovering 20 assignments a year therefore means about 81,600 EUR of extra commission, before counting the hours freed up.

Sanne, COO of a consultant network in Amsterdam (800 active freelancers), picks the Standard scenario at 70,000 EUR. Her 3 account managers spent 9 hours per assignment over 150 assignments, or 1,350 hours a year. With the platform they spend 3.5 hours, or 525 hours: 825 hours saved, valued at 55 EUR loaded cost, or 45,375 EUR a year. Add 12 recovered assignments at 4,080 EUR commission, or 48,960 EUR. Total annual gain: about 94,300 EUR, minus 7,500 EUR of run. Payback comes in roughly 10 months.
FAQ
How much does a consultant matching platform cost in Amsterdam in 2026?
Expect 50,000 to 90,000 EUR depending on scope, with a 4 to 5 month timeline. Annual run cost sits between 5,500 and 10,000 EUR.
Do you need artificial intelligence for good matching?
Not for a pool under 2,000 profiles: a weighted score on skills, availability and rate already yields 80 to 85% relevant suggestions. Semantic search can be added later for 6,000 to 10,000 EUR.
Can contracts be generated automatically?
Yes, from templates approved by your legal counsel, with built-in e-signature. Contracting time drops from 2 days to about 2 hours.
How is the 8 to 12% commission handled?
The rate is set per client or per assignment, then applied to approved timesheets. The dashboard shows real margin per assignment and per account manager.
Does consultant data stay GDPR compliant?
Yes, with hosting in the Netherlands or elsewhere in the EU, defined retention periods and data export on request. This work stream is about 5% of the budget.
