Launch week: every idea card is free.Get Pro

SaaS ideas, mined from what people actually complain about.

Every idea comes from real Reddit posts, was researched against today's competitors, and survived an independent skeptic before it made the list.

Unsynced Retail Stock Data

Retail staff and shoppers waste time on manual inventory checks because stock data is stale, unsynced, or wrong across stores and channels.

In their words

just an easy way for our employees to scan barcodes, upload and have our inventory be updated

r/shopify on Reddit

I was manually handling restock requests and having it automated saved me a lot of time and administrative work.

r/EtsyCommunity on Reddit

one of our clients was having a lot of friction to re-order they have 6 products but over 100 variations.

r/ShopifyAppDev on Reddit

I need to build a simple app that can be used to check materials in and out (and keep track of who has things checked out) via scanning a barcode.

r/webdesign on Reddit

I refunded it instantly because it’s not happening.

r/InstacartShoppers on Reddit

I need a basic OCR tool that can read a vendor's paper catalog and doesn't hallucinate a comma into a decimal point

r/smallbusiness on Reddit

why isn't the myDay search as intuitive as the official Target app? It should just pull from the same place.

r/Target on Reddit

if we were allowed to adjust the order of items in a pick run, that alone would speed things up so much

r/OGPBackroom on Reddit

I feel like every day I’ve come in for the last month there are AT LEAST two new carts of items to be ticketed.

r/MichaelsEmployees on Reddit

Tons of pharmacy items randomly are coming back as not on file, so check lanes are panicking since they can't ring them up.

r/Target on Reddit

seems so difficult to track 50+ items for 3 people

r/Sparkdriver on Reddit

checkout itself, where cart and inventory have to stay consistent while the API throttles and the frontend still has to fail softly

r/nextjs on Reddit

I’d like to know if there’s a way for me to integrate these two ERPs to control product inventory.

I've built a grocery shopping skill, so that it roughly knows what I have in fridge

Why those fall short
