Low Stock & Restock Planner from Sales CSV
Upload your sales and stock exports and see days of stock left per SKU, a reorder point and a suggested purchase list grouped by supplier.
Economics
- Pricing example
- $19 lifetime (free: 20 SKUs)
- Daily math
- 1 sale a day x $19 = $19/day; about 32 sales a month averages $20/day.
- Target if you hit the daily math
- Target: $550 - $800 / month if the daily math is hit
Audience and urgency
Audience: Small online sellers and shops that track stock in spreadsheets and order from a few suppliers.
Urgency: Best-sellers run out right before campaigns while slow items tie up cash. Without inventory software, sellers guess reorder quantities from memory.
MVP scope
- ✓ Upload a sales export (date, SKU, quantity) and a stock file (SKU, on hand, supplier, lead time, minimum order)
- ✓ Average daily sales over a chosen window and days of stock left per SKU
- ✓ Reorder point = daily sales x (lead time + safety days), with a suggested order quantity rounded to the supplier minimum
- ✓ Colour-coded table and a purchase list per supplier
- ✓ Browser-only; Stripe Payment Link unlocks unlimited SKUs
Omitted features
- - Do NOT connect to marketplace or store APIs in Day 1
- - Do NOT forecast with complex models or claim accuracy
- - Do NOT build purchase orders or supplier messaging
