My BigCommerce store is stable and already generating sales, but it needs smarter upsell functionality to reach the next level. I want conversion-focused on every screen size. I also need full-stack support for: • Upselling and optimized checkout flows that surface add-ons, cross-sells, and post-purchase offers without slowing the site down. Especially, buy now pay later promoting/marketing. • Graphic assets that match the upsells (icons, banners, and any custom illustrations). • Coding the redesign directly into BigCommerce (Stencil, HTML/CSS, JavaScript) and keeping performance tight. • Ongoing long-term edits, so any future tweaks or A/B experiments are handled quickly. • Integration with third-party services—think email marketing, reviews, —using BigCommerce APIs or ready-made apps when they make sense. Deliverables will be considered complete once the checkout upsell logic works end-to-end, third-party integrations sync correctly, and Lighthouse scores remain in a healthy range.

Hello, We will implement upsell logic, cross-sell prompts, and BNPL promotion across your BigCommerce store using Stencil, keeping Lighthouse scores healthy. For upsell placement, we will load add-on widgets asynchronously so they render after core content. This prevents layout shift and keeps page speed tight even on mobile. A couple of quick things to confirm: 1) Which BNPL provider are you using (Afterpay, Klarna, other)? 2) Do you have existing graphic assets, or do we need to create those? The number quoted here is a starting estimate. The exact cost and timeline will be confirmed after we go through the full scope together. Looking forward to potentially working together. Thanks, Faizan

Hello, "checkout upsell logic works end-to-end" — this is exactly the part where most BigCommerce stores lose conversion due to blocking scripts or poorly timed BNPL prompts. The real challenge here is adding upsells and BNPL promotion without slowing checkout or breaking Stencil rendering flow. I would implement this by separating the upsell layer into lightweight client-side modules injected into Stencil templates, while keeping API-driven logic for offers and BNPL triggers. Post-purchase offers would be handled asynchronously so checkout speed stays intact. First step would be building a minimal upsell + BNPL placement layer on a staging theme so you can instantly test conversion impact. One key edge case I usually handle here is duplicate or overlapping upsell triggers across cart → checkout → post-purchase flows, which can easily double-charge or annoy users if not deduplicated at session level. I’d design a single offer-state manager to control all triggers across pages. What BNPL provider are you currently prioritizing (Afterpay, Klarna, or mixed routing)? Looking forward to working with you. Srdjan
