# [015] Closed (playbook sample): Shopify app for the EU withdrawal button (Directive 2023/2673,2026-06-19 in force).

The first three took the money; the dozens who entered around the deadline earned close to zero. Closed Inspirational (playbook sample, window closed) · policy window (closed); a sample of a reusable playbook First seen 2026-11-02 · last updated 2026-11-02 Status Closed Why this is written up This is a full example of "a one-time Shopify must-have driven by a regulatory deadline." The rule: those who entered 5 months early, with German localization, and listed first got search ranking and reviews that were almost impossible to displace later. Those who entered a month before the deadline basically wasted their time. Confidence High (the review count distribution is clear). This entry is closed and only kept for comparison. ## Evidence Grouped by store. Each group starts with the charts that can be graphed (real curves, data dates below the chart), then the scanner's original notes and source links. ### Shopify App Store 6 pieces of evidence - Shopify App Store (2026-11-02, live): roughly 2023/2673 withdrawal-button apps with withdrawal / Widerruf / 100 in the name or description, almost all listed in 2026. Review count (a rough proxy for merchants using it): - EW: EU Withdrawal Button & Form (401layers UG, Germany, listed 2026-01-09): 2,321 reviews, 4.9★, lowest paid tier $9.99/month, still 30 new reviews in the last 16 days. - Revoq (BuschBytes, Germany, 03-11): 579 reviews. - Address Check & Withdrawal Pro (ECOMBEAT, Austria, 05-07): 329 reviews. - Anviara (05-06): 106 reviews. - Those listed around or after the deadline (June) and later: the most is Nayvo's EU Withdrawal Button Free (06-03) with 63 reviews; the rest, dozens of them, have 0 to 20 reviews, including many copycat versions from developers in Vietnam, India and Hong Kong. - Shopify App Store (11-02 verified): three leaders: EW: EU Withdrawal Button & Form (eu-widerrufsbutton) 2,321 reviews (11-01 is 2,320), 4.9★, BFS, last 30 days 16, last 90 days 30, free + $9.99 / $29.99; average 234 reviews per month since listing, only 30 in the last 16 days, growth has fallen from its peak. Revoq (eu-withdrawal-form) 579 reviews, 30 days 13, last 90 days 20, free + $9 / $25,11 in several languages. Address Check & Withdrawal Pro (eu-widerruf-pro, ECOMBEAT) 329 reviews, 5.0★, last 30 days 1, last 90 days 10; the pricing is the smartest: Essential $11.99/month includes 150 orders, overage $0.03 per order, Premium $17.99 includes 500 orders, bundling the compliance button with address validation that actually saves returns money, billed by order volume (pricing details from the report). - Shopify App Store (by listing month, name contains withdrawal / Widerruf; report value → 11-02 verified): listed 2026-01 2 apps totaling 2,322 reviews → 2 apps 2,322; 2026-06 (effective month) 32 apps 154 reviews → 29 apps 148 reviews; 2026-08 onward 27 apps totaling 4 reviews → 27 apps 4 reviews. Name-match totals in the report were 128 apps / 3,755 reviews; today it's 103 apps / 3,787 reviews (counting difference). - Shopify App Store (merchant countries from sampled reviews, 11-02 verified): Germany 98 reviews (report 101), Denmark 15, Poland 13, Austria 13, Italy 11, Spain 9; Germany alone is about 40%. The report's inference: Germany's Abmahnung (competitor lawyer letter) culture makes merchants most willing to pay for "legally required page elements." - Shopify App Store (report numbers): "Apps only have opportunity where the law requires a feature, not where it requires text": GPSR (which only requires manufacturer info on product pages) has 59 apps with 126 reviews in total, the top at 74 (today by subtitle count 60 apps / 219 reviews / top 78); the EU Accessibility Act (EAA) has 155 accessibility apps, with the top newly listed in the past year at 31 reviews. - Shopify App Store (report numbers): in a sample of the top app's 30 reviews, 30% were written less than 1 hours after install, many thank it with "kostenlos / gratis," and most reviews come from the free tier. The only 1-star review (09-23, Germany) says the button covered the Impressum in the footer. Compliance tools' biggest risk is creating new non-compliance. ### Other sources (official sites, press releases, web pages) 1 pieces of evidence - Regulation (web, crowell.com, commercraft.com): from 2026-06-19, all online shops serving EU consumers must offer an electronic withdrawal button and confirm receipt of withdrawals to the consumer. ## Already being built (11-02 backfill) Anviara EU Withdrawal Button (wideruf-button, US individual LLC, 05-06) 106 reviews; EU Withdrawal Button Free (eu-withdrawal-button-form, 06-03, developer address in India) 63 reviews, last 30 days 10; BOO (boo-eu-withdrawal-button, Vietnam, 04-20) 52 reviews; EU Widerrufsbutton Pro (eu-widerrufsbutton-1, Germany, 05-12) 50 reviews; the free version from the SlashCart family (seolab-eu-withdrawal) 12 reviews; Complimus Omnibus & Withdrawal (omnibus-price, Hungary, 2022 older app) 74 reviews. 401layers earlier shipped GPSR Compliance & GARAN (gpsr, 2024-09,29 reviews), having already practiced on the previous regulation. ## Reusable playbook Watch EU and national e-commerce compliance obligations about to take effect, and publish half a year before the effective date (inference: Shopify, WooCommerce and Shopware follow the same playbook; we have no WooCommerce or Shopware data). We haven't found the next confirmed deadline today; if one turns up later, it gets its own record. ## Should every product builder know this? Yes (especially for e-commerce plugin builders). ## Change log 2026-11-02 Backfill (from Shopify App Store New Opportunities (Batch 1) §1.1 first half, §3.3): added the review distribution by listing month, the German merchant share, "law requires a feature vs. requires text" (GPSR and EAA side by side), and ECOMBEAT's per-order pricing. Today I verified eu-widerrufsbutton 2,321, eu-withdrawal-form 579 and eu-widerruf-pro 329, consistent with the report; the June listing cell is 29 apps / 148 reviews (report 32 / 154, counting difference).
