My store already runs on Prestashop 8, but several core features need polishing so the shopping experience feels smoother and more reliable. The immediate focus is on functionality improvements rather than design tweaks. I’d like you to review the current setup, pinpoint bottlenecks, and implement practical fixes or optimisations that deliver a measurable difference in speed, accuracy, and usability. At this stage I’m not entirely sure whether new custom modules will be necessary; I’m open to your recommendations. If an off-the-shelf module solves the issue elegantly, great—otherwise I’ll rely on your expertise to scope and build a lightweight custom solution that integrates cleanly with Prestashop 8’s architecture and respects future upgrade paths. Please share examples of similar functionality work you’ve completed on Prestashop 8 (or 1.7 if that’s what you have), outline the approach you’d take to diagnose the site, and estimate a realistic timeline for rollout and testing. I’ll provide full back-office access, staging credentials, and a clear list of pain points once we start.
