Document verification has a high failure rate across the industry — according to SumSub, up to 50% of KYC checks require resubmission (poor lighting, blurry photos, expired documents, mismatched data). Wert was no exception. Verification for larger purchases can take minutes or hours, so few stay on screen. Users rely on follow-up emails to complete the process.
After a necessary major security update, we changed how the widget could be triggered (the details are sensitive). The resubmission flow broke: users could no longer return to their verification directly from emails and had to restart the entire purchase from the partner's website. Re-verification drop-off rose from 52% to 64%. High-value user KYC recovery fell from 15% to 9%.
Approach
Map the full journey, not just the break. After a UX audit, the problems went beyond broken links. Emails didn't reflect the case or context, had no design, and were easily replicated by fraudsters. Support couldn't help users without routing them through partner sites. No tracking to understand where users dropped.
Reframe the problem. Resubmission isn't a checkout retry. It's a separate user journey with different context, timing, and trust. Users come back hours or days later, often from a different device, with little context of where they left off. I proposed separating resubmission from the purchase flow entirely with a standalone widget that works without a partner session.
Redesign every touchpoint. Transactional emails redesigned for clarity, branding, and trust. Direct resubmission link for Support. So, we no longer send users to partner sites for KYC issues. Amplitude tracking across the new flow so we could see what was actually happening.
Drive it across squads. This wasn't on my squad's roadmap. I saw the drop-off numbers, made the case for urgency, set up the work with a frontend lead outside my squad, and we shipped everything within a month.
Impact
- New standalone resubmission flow. Users could now return and complete verification directly, from any channel.
- Redesigned emails with clear context, step-by-step guidance, and trustworthy design.
- Re-verification drop-off: 52% before → 64% after security update → 27% after release.
- High-value user KYC recovery (failed → completed): ~15% before → 9% after security update → ~17% after release and held steady at ~18% median over the following quarter.
