The verdict in three sentences
A multi-currency B2B e-commerce platform for export in Singapore costs between 40,000 and 90,000 EUR in 2026, covering currencies, tax/customs and international payments. The real issue is not showing a price in dollars, but correctly handling export taxes and cross-border payment costs. Plan for 5 to 9 months of delivery and roughly 600 EUR/month in support.
What a B2B export platform covers
Selling internationally adds layers: currencies, languages, per-country tax rules, incoterms, customs documents. 2026 breakdown.
| Line item | 2026 range (EUR) | Detail |
|---|---|---|
| Discovery + multi-country UX | 5,000 - 11,000 | Per-market journey, languages, currencies |
| Multi-currency engine | 6,000 - 15,000 | Rates, rounding, net/gross display |
| Tax + customs rules | 7,000 - 18,000 | Per-country tax, export exemption, HS codes |
| International payment | 5,000 - 14,000 | Cards, SEPA/SWIFT transfer, global PSP |
| Languages + content | 4,000 - 12,000 | Translations, datasheets, legal notices |
| ERP + logistics connector | 6,000 - 16,000 | Sync, carriers, export documents |
| Project total | 40,000 - 90,000 | Operational export platform |
The tax/customs line is the most underestimated: between cross-border VAT/GST, export exemptions and customs codes, fine configuration is needed (7,000 to 18,000 EUR).
The hidden cost of cross-border payments
In export, payment fees weigh on margin. 2026 orders of magnitude by payment method.
| Payment method | Typical 2026 fees | Settlement time | Note |
|---|---|---|---|
| International card | 1.8 - 3.2% | 2 - 3 days | + FX fee 1-2% |
| SEPA transfer (EU) | 0 - 1 EUR/txn | 1 - 2 days | Ideal intra-EU |
| SWIFT transfer (non-EU) | 15 - 50 EUR/txn | 2 - 5 days | + correspondent bank fees |
| Global PSP (multi-currency) | 1.5 - 2.9% + FX | 1 - 3 days | Simplifies reconciliation |
| Letter of credit | 0.5 - 1.5% of value | 5 - 15 days | Secured large orders |
On an average B2B order of 8,000 EUR, a card at 2.5% plus 1.5% FX costs roughly 320 EUR in fees, versus a few euros for a bank transfer: steering large customers to transfer protects margin.
Mini case study
Wei Lin leads export at a food manufacturer in Singapore: sales into 12 countries, average order 8,000 EUR, roughly 600 international orders/year. She invests 62,000 EUR in a multi-currency platform with tax/customs rules and mixed card + transfer payment, plus 600 EUR/month support. By steering 70% of orders to bank transfer, she saves roughly 140,000 EUR/year in payment fees versus card-only. The platform pays back in under 6 months on that line alone.

FAQ
How do you handle export tax?
The platform configures tax per country: exemption outside the customs union with proof, reverse-charge intra-union with a valid tax number. This configuration costs 7,000 to 18,000 EUR depending on country count.
One global PSP or several local ones?
A global multi-currency PSP simplifies reconciliation but charges FX and commission. For large orders, transfer remains cheapest. The two are often combined.
Does the platform handle customs documents?
It can generate commercial invoices, packing lists and embed HS codes. Full customs paperwork often goes through the carrier or a logistics connector.
How many languages should we plan?
Usually 2 to 4 at launch (EN plus 1-2 target markets). Each extra language adds translation and content maintenance (part of the 4,000-12,000 EUR line).
What is the maintenance budget?
Roughly 7,200 EUR/year (600 EUR/month) for support, plus FX-rate and tax-rule updates. Major regulatory changes are quoted separately.
