This article ranks the top ten B2B payment gateways tailored for Singapore e-commerce, providing key facts on fees, settlement times, and local business features to help merchants choose efficiently.
1 PayNow Corporate Bank Transfer Solution
Singaporean businesses widely use PayNow Corporate for instant bank transfers between local banks. It leverages the FAST system, enabling real-time settlement with no transaction fees for most peer-to-peer transfers between DBS, OCBC, UOB, and others. Major e-commerce platforms integrate it for B2B invoice payments, reducing payment friction. However, it lacks global card acceptance and chargeback protections often needed for cross-border trade.
2 Stripe B2B Recurring Payment Engine
Stripe powers over 60% of Singapore e-commerce startups with its robust B2B invoicing and subscription management. It supports local payment methods like PayNow and GrabPay alongside international credit cards. Stripe’s Smart Retries feature automatically retries failed payments for recurring invoices, minimizing revenue loss. Transaction fees are 2.9% plus $0.50 SGD per successful charge, with no monthly minimums.
3 PayPal Business Invoice Gateway
PayPal Business remains a trusted B2B gateway for Singaporean firms due to its global buyer protection and familiarity. Over 40% of local B2B invoices are sent via PayPal, and it offers batch payment capabilities for vendor settlements. The fee is 3.9% plus a fixed $0.50 SGD per transaction for domestic invoices. PayPal supports 25 currencies, simplifying cross-border invoicing.
4 Adyen Unified Commerce Platform
Adyen provides a single platform for both online and in-store B2B payments, widely adopted by Singaporean marketplaces like Carousell. It processes multiple local schemes including NETS and PayNow. Adyen’s revenue share model charges a flat fee of 0.85% per transaction plus a small per-authorization cost. Settlement occurs within 48 hours, critical for inventory-intensive B2B operations.
5 Square Invoicing for Small Merchants
Square’s invoice module enables Singaporean SMEs to send payment links via email or SMS for B2B orders. It supports credit and debit cards with a 2.9% fee per transaction, and instant transfers to any local bank account for an additional 1% fee. Square’s inventory sync feature automatically updates stock levels when payments are confirmed, reducing manual reconciliation.
6 Alipay Global Cross Border Gateway
Alipay Global offers a dedicated B2B cross-border payment solution for Singapore merchants selling to China. It handles both buyer and seller accounts with anti-fraud tools tailored for high-value transactions. The gateway charges 2.5% per transaction with no hidden currency conversion markups. Over 700 million Chinese consumers use Alipay, creating a massive B2B demand.
7 WeChat Business Payment Integration
WeChat Business allows Singapore e-commerce sites to accept payments from Chinese corporate buyers via WeChat Pay. It integrates seamlessly with WeChat’s CRM and marketing tools. The fee is 2.8% per transaction, with same-day settlement available for verified merchants. Despite lower adoption in Singapore, it remains essential for B2B sales targeting Mainland China corporate clients.
8 Grab Pay Biz for Local Market
Grab Pay Biz extends Grab’s consumer payment network to B2B transactions, especially for food and logistics suppliers in Singapore. It processes payments directly from GrabPay wallet balances, bypassing expensive card networks. Fees are capped at 1.5%, among the lowest for local B2B gateways. Settlement is instant, making it ideal for high-volume, low-margin wholesale orders.
