01Days-of-supply calculated per SKU the moment you paste your inventory data — no spreadsheet setup required.
02Reorder-now alerts flag SKUs where stock will hit zero before your supplier can replenish them.
03Exact reorder quantity per SKU based on your velocity, lead time, and safety stock buffer — not a rough guess.
04Handles inbound shipments already on the way, so you don't double-order a SKU that's en route to FBA.
05Seasonal SKUs handled: tell it your peak velocity and it recalculates days-of-supply before Q4 bites you.
06Accepts Seller Central exports, Helium 10, Inventory Lab, or plain pasted text — no reformatting needed.

What it does

You know which SKUs are running low. What you don't have is five minutes to open a spreadsheet, update formulas, and cross-reference lead times for every product — not when you're also dealing with PPC, supplier emails, and listing issues. This skill takes whatever inventory data you have — pasted from Seller Central, exported from Helium 10 or Inventory Lab, or just typed freehand — and produces a complete FBA inventory replenishment dashboard on the spot. The output is a trifecta: days of supply for every SKU, color-coded reorder-now alerts for anything that will stock out before your supplier can ship, and a calculated reorder quantity that accounts for your actual lead time plus safety stock buffer. It handles edge cases that break simple formulas — inbound shipments already in transit, zero-velocity new SKUs, bundle components, seasonal velocity spikes, and hybrid FBA/FBM setups. The bundled `replenishment-formulas.md` shows every calculation with worked examples, and `edge-cases-and-gotchas.md` covers the messy real-world scenarios that trip up generic tools. This skill is built for FBA sellers running 5–50 SKUs who need a real answer fast, not another dashboard subscription to maintain. If you've ever stocked out of a top seller because the reorder math lived in your head, this is the fix.

Frequently asked

Does it just show me days of supply, or does it also tell me how many units to reorder?
Both, plus the stock-out date. You get days of supply per SKU, a reorder-now flag for anything that will hit zero before your lead time is up, and the exact reorder quantity based on your velocity, lead time, and safety stock target — all in one dashboard.
I have an inbound shipment already on the way — will it factor that into the calculation?
Yes. Tell it how many units are inbound and when they're expected to check in at FBA, and it nets that against your projected demand so you don't accidentally double-order.
Can I just build this myself in a spreadsheet instead?
You can, and if you already have one that's current and trusted, keep using it. This skill is for the moments when you don't have the spreadsheet open, the data is sitting in Seller Central, and you need an answer in the next three minutes.
What data format does it accept — does it have to be a specific export from Seller Central?
No specific format required. It parses Seller Central exports, Helium 10 and Inventory Lab reports, or plain text you type or paste. The bundled data-input-formats.md guide covers every common format and what to do if your columns are labeled differently.
Will it work for a seasonal SKU where my velocity triples in Q4?
Yes — tell it your peak daily velocity and when the season starts, and it recalculates days of supply and reorder timing against that number instead of your current slow-season average. The edge-cases-and-gotchas.md bundled guide covers seasonal planning specifically.
