would love feedback - Building a digital receipt + customer intelligence tool for retail.

I've been building a product that rethinks the paper receipt — turning it into a digital touchpoint that helps retail and food businesses actually retain and understand their customers, instead of losing them the moment they walk out the door.

The core problem I'm trying to solve: most small and growing businesses have no idea who their repeat customers are, no easy way to reach them again, and no simple way to understand what's actually driving sales. Existing solutions tend to require heavy POS replacements or enterprise-level data tools, which puts them out of reach for a lot of business owners.

What I'm building includes digital receipts, automatic loyalty recognition, a simple customer dashboard, and plain-language AI insights (like flagging at-risk customers or peak hours) — designed to sit on top of a business's existing setup rather than replacing it.

I'm still in active development and testing with real merchants, and I'd genuinely like input from this community, especially if you've built something in retail tech, loyalty, or POS-adjacent spaces:

• Have you seen products try to solve this "customer disappears after purchase" problem before, and what made them succeed or fail?

• For those who've sold into small/mid-sized businesses, what's usually the biggest blocker to adoption — price, integration effort, or something else?

• Is there a feature here that seems like a "nice to have" versus something that would actually change behavior?

Would appreciate any perspective, whether from experience building similar things or just as someone who's dealt with this as a customer or business owner.
