PayPick

For EU online shoppers, a browser extension that shows which payment method unlocks the most cashback or loyalty points at checkout — including Wero, iDEAL, Klarna, and your bank's card — so the cheapest option is one tap away.

Target user

EU online shoppers who care about maximizing rewards and are now facing a real choice between payment methods

Features
  • Auto-detects the checkout page and surfaces a ranked list of payment methods by net rewards, factoring cashback, loyalty points, and any per-method fees
  • One-click redirect to the chosen payment rail (Wero, iDEAL, Klarna, Bancontact, card) so you stay in the checkout flow
  • Monthly savings tracker shows how much you saved in € and which payment method gave you the most value across retailers
  • Privacy-first design: only reads the public checkout page metadata, never touches card numbers or bank credentials
Why now

Wero just hit 56M users and is going live at Decathlon Germany, with Lidl, Rossmann, and Hornbach queued up — the EU payment landscape is fragmenting and shoppers will increasingly face a real choice at checkout without knowing which is best for them.

Demand
6/10

Wero is genuinely going live with major EU retailers (Decathlon, Lidl, Rossmann, Hornbach) and payment fragmentation is real, but the target audience of rewards-optimizing EU shoppers who actively choose between Wero/iDEAL/Klarna/card is a niche subset of the cashback-extension user base (Rakuten/Honey/Capital One Shopping).Wero E-Commerce Payments Go Live in Germany and Belgium with Major MerchantsBest Automatic Cashback Browser Extensions 2026: Tested

Whitespace
7/10

A targeted search for a 'payment method optimizer' extension comparing Wero/iDEAL/Klarna/cashback returns no direct competitor; existing tools (Rakuten, Honey, Capital One Shopping) optimize store-level cashback and coupons but do not cross-compare payment-rail rewards at checkout — a genuinely novel angle, though adjacent giants could trivially expand.Wero E-Commerce Goes Live in Germany - First Merchant Payments for European Payment InitiativeBest Cashback Apps and Browser Extensions Compared

Monetization
5/10

Free cashback tools dominate the category and users show low willingness to subscribe for a checkout overlay; realistic revenue is thin affiliate/lead-gen fees from PSPs and card issuers rather than direct user payment, and payment-method affiliate economics are weaker than merchant cashback.Best Automatic Cashback Browser Extensions 2026: TestedMonetization Models for Browser Extensions: From Free to Premium

Longevity
8/10

EU payment fragmentation is structural and policy-driven (EPI/Wero, PSD2, sovereignty push to reduce Visa/Mastercard fees); confirmed live e-commerce rollout in DE/BE/FR with queued major retailers makes the trend multi-year, not a fad.Wero 2025/2026 - The European payment engine is picking up speedThe $24 Trillion Divorce: Wero's Impact on Payment Giants

Feasibility
5/10

Detecting the payment options on a checkout page is doable, but the hard parts are: (1) maintaining a live database of which merchant supports which PSP and the cashback/loyalty delta per payment rail, (2) integrating with each PSP/bank to surface accurate user-specific rewards, and (3) staying reliable across wildly different checkout stacks — a meaningful data and partnership burden, not a weekend project.Wero E-Commerce Payments Go Live in Germany and Belgium with Major MerchantsWero, a European alternative to Visa and Mastercard - Cybernews
