The verdict in three sentences
For a marketplace of technical service providers in Europe, escrow through a licensed payment partner (Stripe Connect or Mangopay) is the only sensible route in 2026: it spares you from applying for a payment institution or agent licence with the regulator. Budget 1.4% to 2.9% in transaction fees plus payout fees, and EUR 15,000 to 40,000 excl. VAT to build the hold, sign-off and dispute flow. The real return comes from the dispute procedure: well designed, it keeps disputes below 2% of jobs.
Why escrow changes the game in B2B
On a marketplace for industrial maintenance, energy audits or transport, the buyer fears paying for a badly executed job, and the provider fears never being paid on 45-day terms. Escrow addresses both: funds are collected at order, held in a ring-fenced account at the payment institution, then released to the provider when the client signs the completion report or when a dispute window expires (often 7 to 14 days).
The key legal point: as soon as your platform collects funds on behalf of third parties, you are carrying out a regulated payment activity. By relying on a licensed partner that holds the funds, you stay within the exemption or the mandated platform model, without building a regulator file (6 to 12 months and EUR 125,000 minimum capital for a payment institution).
| 2026 provider | Transaction fee (EU cards) | SEPA transfer / direct debit | Provider payout | Provider KYC | Native escrow |
|---|---|---|---|---|---|
| Stripe Connect (Custom) | 1.5% + EUR 0.25 (+ 0.25% Connect) | EUR 0.35 to 0.80 | 0.25% + EUR 0.10 per payout | Included, EUR 2 per active account/month | Via delayed payouts, up to 90 days |
| Mangopay | 1.4% to 1.8% + EUR 0.18 (negotiated) | EUR 0.50 to 1 | EUR 0.25 to 0.50 per transfer | Included, volume based | Yes, dedicated wallets |
| Lemonway | 1.5% to 2.5% depending on volume | EUR 0.40 to 0.90 | EUR 0.30 to 0.60 | Included | Yes, payment accounts |
| Adyen for Platforms | Interchange++ + about EUR 0.13 | Per contract | Per contract | Included | Yes, for large volumes |
| Own licence (PI) | Direct bank cost | Direct bank cost | Direct bank cost | Your responsibility | To build, regulator file |
Order of magnitude for 2026, before negotiation: below EUR 2M of annual volume, Stripe Connect and Mangopay are within 0.3 points of each other. Above that, Mangopay and Adyen become more attractive on high B2B tickets (EUR 2,000 to 20,000 per job), because SEPA transfer replaces cards.
What you need to build and what it costs
The payment partner provides accounts and held funds, not the business logic. You code the job state machine: ordered, funded, in progress, delivered, approved, disputed, arbitrated, refunded or paid out.
| Component | Scope | 2026 budget excl. VAT | Timeline |
|---|---|---|---|
| Provider onboarding and KYC | Company registration, ID, bank details, verification status | EUR 3,000 to 6,000 | 1 to 2 weeks |
| Collection and hold | Card, SEPA, bank transfer, deposit or milestone payments | EUR 4,000 to 9,000 | 2 weeks |
| Sign-off and release | Completion report, automatic dispute window | EUR 2,500 to 6,000 | 1 to 2 weeks |
| Dispute module | Opening, attachments, mediation, partial refund | EUR 3,500 to 10,000 | 2 to 3 weeks |
| Commission and invoicing | Platform fee, invoices on behalf of providers, VAT | EUR 2,000 to 6,000 | 1 to 2 weeks |
| Back office and reporting | Reconciliation, accounting export, alerts | EUR 0 to 3,000 | 1 week |
| Total | EUR 15,000 to 40,000 | 8 to 12 weeks |
Milestone payments (30% at start, 70% on delivery) are the most requested option for long audit or maintenance jobs. They add EUR 2,000 to 4,000 to the budget but significantly reduce the provider's tied-up cash.
Keeping disputes below 2%
Platforms with more than 5% disputed jobs nearly always share the same flaw: a vague job scope. Three rules are enough to get back below 2%: a structured job sheet (deliverables, date, acceptance criteria), time-stamped proof of delivery (geotagged photos, PDF report, signed delivery note) and a short dispute window with automatic release. The internal mediator should decide within 5 working days; beyond that, plan for referral to an external mediator or an arbitration clause for business-to-business disputes.

Julien, founder of an HVAC maintenance provider marketplace in Lyon, handles 180 jobs per month with an average ticket of EUR 2,400, or EUR 432,000 of monthly volume. With Mangopay negotiated at 1.5% on average (card and SEPA mix) and EUR 0.40 per payout, his payment fees come to about EUR 6,550 per month. His 12% commission brings in EUR 51,840. Before escrow, 6% of jobs ended in non-payment or long disputes, that is 10.8 jobs and nearly EUR 26,000 of blocked volume each month. After a EUR 28,000 build, the dispute rate falls to 1.8%, or 3.2 jobs. The secured commission on the 7.6 recovered jobs is worth about EUR 2,190 per month, plus support hours saved (about 25 h per month at EUR 45, i.e. EUR 1,125). Payback: about 8.5 months.
FAQ
Do I need a payment licence to run escrow on a marketplace?
No, as long as funds are held by a licensed payment or e-money institution such as Stripe, Mangopay or Lemonway and you act as a mandated platform. Your own licence requires about EUR 125,000 in capital and 6 to 12 months of review.
How long can funds be held?
Stripe Connect lets you delay a payout by up to 90 days in most European countries. Mangopay and Lemonway accept longer periods on dedicated wallets, to be agreed contractually based on actual job duration.
Does escrow work with SEPA transfers?
Yes, and it is recommended above a EUR 1,500 ticket: cost drops to EUR 0.35 to 1 per transaction instead of 1.5% on cards. Collection takes 1 to 2 working days, which must be built into the job start date.
Who invoices the end client?
The provider invoices the service, often through a billing mandate given to the platform, and the platform invoices its commission separately. Plan EUR 2,000 to 6,000 of development to automate both flows with the correct VAT.
What if the client never approves the job?
A 7 to 14 day dispute window with automatic release protects the provider. Without a reasoned dispute within that window, funds are paid out, which removes most abusive holds.
