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
I was manually handling restock requests and having it automated saved me a lot of time and administrative work.
one of our clients was having a lot of friction to re-order they have 6 products but over 100 variations.
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.
I refunded it instantly because it’s not happening.
I need a basic OCR tool that can read a vendor's paper catalog and doesn't hallucinate a comma into a decimal point
why isn't the myDay search as intuitive as the official Target app? It should just pull from the same place.
if we were allowed to adjust the order of items in a pick run, that alone would speed things up so much
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.
Tons of pharmacy items randomly are coming back as not on file, so check lanes are panicking since they can't ring them up.
seems so difficult to track 50+ items for 3 people
checkout itself, where cart and inventory have to stay consistent while the API throttles and the frontend still has to fail softly
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
Retail staff and shoppers
Where they talk
- r/Target
- r/shopify
- r/InstacartShoppers
- r/InventoryManagement
- r/Sparkdriver
- r/walmartogp
- r/smallbusiness
- r/kroger
Tools they use today
- Shopify
- Excel
- Instacart
- Square
- Claude
- DoorDash
- Google Sheets
Why those fall short
- no way to route custom prep requests to store staff
- search returns 90k results, misses items, crashes, slow
- timer ignores real shelf conditions and interruptions, wastes time
- title searches return pages of results or no results; stock edits not saved
- enterprise AI tools hallucinate values and cost too much
