1. Core App (Freemium): The core expense tracking, list management, and settlement features are provided entirely free of charge. All users can create unlimited lists, add expenses, invite participants, and use the settlement algorithm at no cost.
2. Payment Processing Fees: When users opt to pay or receive money through the app via iDEAL, Wero, or Bancontact, a service fee of €0.35 per transaction is charged. Bank account verification also incurs a one-time €0.35 fee. This is a usage-based transaction fee model.

Expansion highlights4 records

Direct peers

• Tricount: Tricount is a group expense management app owned by BNP Paribas serving primarily European markets. It competes directly with WieBetaaltWat on shared-expense tracking and multi-person settlement, offering similar core features for friends, households, and travel groups.
• Splid: Splid is a German expense-splitting app offering group expense tracking and settlement with a near-identical core feature set to WieBetaaltWat. It is a direct competitor in German-speaking markets where WBW also operates via its Splitser brand, making it a regional head-to-head rival.
• Splitwise: Splitwise is the global leader in group expense-splitting apps, founded in 2011 and headquartered in the US. It offers essentially the same core product as WieBetaaltWat and is the primary global competitor — which is why WBW built a dedicated CSV migration tool targeting Splitwise users directly.

Broad incumbents

• N26: N26 is a European mobile bank offering P2P payments and shared-spending features (Spaces, Shared Spaces). It is a broad incumbent that increasingly competes with WBW by integrating group expense and shared budget functionality into its core banking app across Germany and other WBW markets.
• Revolut: Revolut is a European fintech super-app offering multi-currency accounts, P2P payments, and increasingly expense-tracking and group-payment features. As it expands into shared-bill functionality, it competes indirectly by bundling group-payment capabilities into a broader financial super-app used by millions in the same geographies as WBW.
• ING (Tikkie / Wero): ING is a major Dutch bank whose Tikkie payment-request brand has been migrated into the pan-European Wero standard. ING competes for the same Dutch user moments as WieBetaaltWat by bundling shared-expense and payment-request features directly into its banking app, where Tikkie alone has driven billions of payment requests in the Netherlands.

Regional players

• ABN AMRO: ABN AMRO is a major Dutch bank offering payment-request features (also contributing to Wero) within its core banking app. It serves the same Dutch primary market as WieBetaaltWat and pressures WBW by bundling similar functionality into an app users already have installed for daily banking.
