What Sisow does

Sisow is a Collecting Payment Service Provider headquartered in Helmond, Netherlands, operating as a payment solutions brand within the broader Buckaroo platform — a Dutch PSP registered with the KVK under number 04060983 and headquartered in Utrecht. Founded in 2011, Sisow delivers an integrated payment product portfolio spanning online payment methods (iDEAL, credit cards, PayPal, Wero, Pay by Bank, iDIN), in-person acceptance via fixed and mobile PIN terminals and a Tap to Pay solution that turns Android smartphones into contactless terminals, and a 360-degree omnichannel proposition aimed at unifying payment experiences across physical and digital touchpoints. The platform is supported by a documented API (docs.buckaroo.io) and downloadable payment plugins for six major e-commerce platforms — CCV Shop, Lightspeed, Magento, Shopify, Shopware 6, and WooCommerce — which serve as the primary distribution surface for SMB and mid-market merchants.

Beyond core acceptance, Sisow/Buckaroo layers enterprise modules on top of the payment rail: Credit Management for friendly AR follow-up, Subscription Management for recurring billing, Payment Plaza as an enterprise payment platform, Smart Checkout, Digital Wallet, and Split Payments for multi-party settlement. The combined offering is positioned as a horizontal payment solution rather than a vertical specialist, targeting general merchants, e-commerce/webshop operators, and enterprise customers requiring customized infrastructure. Distribution is dual-track: a self-service online signup flow for SMBs and an enterprise field-sales motion for larger accounts, with a Buckaroo Plaza customer portal and My Buckaroo access for existing merchants.

The business model is a transaction-fee-driven PSP model with quote-based pricing that is not publicly disclosed. Customers are segmented horizontally across use cases (general merchants, e-commerce, enterprise) rather than by industry vertical. Revenue mechanics rest on payment-processing margins across online and in-person rails, hardware rental/lease/sale of PIN terminals, and value-added enterprise modules. Geographic focus is the Netherlands with localization suggesting adjacent Benelux reach (Belgian Dutch/Flemish, English-LU, French-LU, German, French). Sisow has no disclosed funding rounds, M&A activity, leadership changes, or standalone financials in the source material; the relevant operational, marketing, and developer-distribution assets are shared with parent Buckaroo.

Broad incumbents

• Stripe: Global payments incumbent with online checkout, POS, subscription billing, and Smart Checkout capabilities. Competes with Sisow for the same e-commerce platforms (Shopify, WooCommerce, Magento) and increasingly for European enterprise merchants.
• Adyen: Amsterdam-based global payments platform offering online, in-person, and omnichannel acceptance plus enterprise modules. Competes with Sisow in the Dutch enterprise segment while operating at vastly greater scale across Europe and beyond.
• Worldline: European payments incumbent offering merchant acquiring, POS terminals, and omnichannel solutions across Benelux; competes with Sisow in Dutch enterprise and omnichannel segments while operating a much broader portfolio.
• Checkout.com: Global payment service provider with strong European enterprise coverage and Smart Checkout optimization; competes with Sisow for mid-market and enterprise Dutch merchants needing higher-value cross-border acquiring.

Emerging players

• SumUp: European SMB-focused mPOS and online payments provider with strong Tap to Pay and terminal offerings; competes directly with Sisow in the Dutch micro-merchant and SMB segment.
• Klarna: European BNPL and full-service payments provider operating in the Netherlands with online checkout integrations and merchant tooling; partial overlap with Sisow's e-commerce plugin strategy and merchant base.

Direct peers

• CCV: Dutch in-store payments specialist providing fixed and mobile POS terminals, Tap to Pay, and integrated checkout software; both a Sisow integration partner and a direct competitor in the PIN-terminal product line.
• Mollie: Amsterdam-headquartered PSP serving SMB and mid-market merchants with multi-method online checkout, plugins for the same e-commerce platforms (Shopify, WooCommerce, Magento), and a strong Dutch/Benelux footprint — the closest like-for-like competitor to Sisow.
• MultiSafepay: Dutch PSP with very similar product mix to Sisow: iDEAL, credit cards, PayPal, afterpay, plugins for WooCommerce/Magento/Shopify, and POS solutions. A direct head-to-head competitor in the Dutch SMB and webshop segment.
• Pay.nl: Netherlands-based payment service provider offering online checkout, point-of-sale terminals, and a broad plugin ecosystem, directly overlapping Sisow's target SMB and webshop merchant base.
