Three European payment rails compete for research peptide order flow in 2026 — iDEAL (Dutch consumer-flow), SEPA (institutional standard), and the new Wero (EU-wide instant). Each fits a different order context. This is the side-by-side comparison.
The three rails at a glance
| iDEAL | SEPA | Wero | |
|---|---|---|---|
| Geography | Netherlands only | EU-wide | EU-wide (rolling out) |
| Settlement | ~10 seconds | 1–2 business days | ~10 seconds |
| Consumer flow | Excellent (bank-app) | Adequate | Excellent (mobile-first) |
| Institutional flow | Limited (lab budget orders) | Excellent | TBD as it matures |
| Confirmation | Instant | Delayed | Instant |
| Fees | Low (~€0.30) | Free | Low |
| Market share NL | ~80% online | ~15% institutional | <5% (growing) |
iDEAL — the consumer/individual researcher rail
Fits:
- Individual researchers placing orders against personal budget or institutional credit cards
- Lab budget orders under €1,000
- Anyone with a Dutch bank account ordering for Dutch addresses
- Same-day-dispatch orders where instant confirmation matters
Doesn’t fit:
- Large institutional procurement workflows
- Non-Dutch researchers (account must be at Dutch bank)
- Pre-approved bulk PO orders that require invoice-then-pay flow
See our iDEAL guide for full detail.
SEPA — the institutional standard
Fits:
- University procurement (UMC, KNAW institutes, research universities)
- Pharmaceutical company R&D departments
- Hospital research divisions
- Bulk orders over €1,000 requiring formal invoicing
- Multi-supplier procurement workflows with consolidated payment
Doesn’t fit:
- Same-day-dispatch orders (SEPA 1–2 day settlement delays dispatch)
- Cross-EU orders where iDEAL or Wero would be faster
- Individual researcher convenience
SEPA invoicing flow:
- Order with “SEPA / Bank Transfer” payment method
- Receive invoice immediately
- Procurement team processes payment via bank transfer (1–2 days)
- Funds clear, order moves to dispatch
- Total order-to-delivery: 3–5 days
Wero — the future consumer flow
Fits (when available at your bank):
- Cross-EU orders where you want instant payment but iDEAL isn’t available
- Mobile-first order flow (researchers ordering from phone)
- Future-proofing payment infrastructure as European banks consolidate
Doesn’t fit (yet):
- Researchers whose bank hasn’t rolled out Wero yet (most NL banks still rolling)
- Institutional procurement (institutional Wero adoption is years away)
See our Wero introduction article.
Decision tree for research peptide orders
Use this to pick the rail that fits:
- Individual order <€1,000, Dutch bank account, want same-day dispatch → iDEAL
- Institutional order >€1,000, formal invoicing required → SEPA
- Individual order, non-Dutch EU bank, want instant → Wero (if your bank supports it) or local equivalent (Bancontact, etc.)
- One-time bulk order requiring approval workflow → SEPA
- Recurring research orders, want streamlined flow → iDEAL (or Bunq Pay if Dutch fintech account)
What Chempeptides supports
All three rails are supported on Chempeptides checkout:
- iDEAL via Mollie payment processing — instant confirmation, all major Dutch banks
- SEPA bank transfer for institutional orders — invoice generated on order, settlement on transfer receipt
- Wero — rolling out as Dutch banks complete integration in 2026
- Plus: Bunq Pay (Dutch fintech), card processing as fallback
What we don’t support — and why
We don’t accept crypto-only payments. Reason: legitimate EU research suppliers operate through regulated banking infrastructure. Crypto-only suppliers typically can’t pass payment-processor KYC requirements — which is itself a supplier-quality signal. See our red flags article.
The bottom line
For most Dutch researchers placing personal-budget orders: iDEAL. For institutional procurement: SEPA. For future-proofing and cross-EU orders: Wero as it matures. Chempeptides supports all three rails to fit every research order context.
