# I read 1-star reviews before building. This time, it killed my Shopify app idea. > Source: > Published: 2026-06-22 07:48:53+00:00 I was considering a small Shopify returns/exchange idea. Before sketching features, I did a deliberately boring check: The result was not a better feature list. It was a kill decision: I would not start by building another full returns platform. The category has real pain, but the complaints that looked promising were attached to heavy operational work: A small team could enter the category thinking it is building software, then quickly get pulled into merchant-specific operations. The narrower angles looked more believable: The part I am still unsure about: Is this kind of pre-build complaint review a useful step for founders, or is it just basic homework everyone should do themselves? Questions: I am intentionally not linking a product page here. I am trying to test the decision value of the research step first.
