It's a calculation.

Cadence calculated this timeline using your last 90 days of sales velocity, your saved supplier lead times, and your FBA inbound buffer. You waited too long — order today.

01

Connect your Amazon account

Cadence syncs your inventory levels, sales history, and ASIN data directly from Seller Central. Setup takes under five minutes.

02

Enter your supplier lead times

Production days, shipping method, FBA check-in buffer — set it once per supplier. Cadence applies it to every SKU you source from them.

03

Get your reorder alerts

Each morning, Cadence sends a prioritized list: which SKUs need ordering today, and exactly how many units — calculated from your current velocity and lead time.

Built for real supply chains

Every feature exists because
a seller lost money without it.

Per-supplier lead times

Your supplier takes 28 days, not 14. Cadence knows that.

Set production time, shipping method, and FBA inbound buffer separately for each supplier. When you add a new SKU from that supplier, the lead time is already there — no manual entry per product.

  • Production run time (per SKU or supplier default)
  • Ocean, air, or express shipping options
  • Amazon FBA inbound processing buffer
  • Seasonal demand multipliers for Q4

Supplier Profile — Guangzhou Factory A

Production time 21 days
Ocean freight (LA port) 32 days
FBA inbound buffer 7 days
Total lead time 60 days

Demand Forecast — Q4 Adjustment Active

+47% demand increase detected for Nov–Dec based on last 2 years. Reorder quantity adjusted automatically.

Historical demand trends

Q4 is coming. Cadence started planning in August.

Cadence analyzes two years of your sales data to detect seasonality patterns. It automatically adjusts your reorder quantities and timing before demand spikes — not after you stock out.

  • Seasonal demand multipliers from historical data
  • SKU-level trend detection (growth or decline)
  • Prime Day and Black Friday planning windows
  • Velocity recalculated every 24 hours
Daily reorder alerts

One email every morning. No dashboard required.

Each day, Cadence sends you a prioritized reorder list — SKUs that need ordering today, the exact quantity to order, and a direct link to your purchase order template. Act on it in under five minutes.

  • Sorted by urgency — critical stockouts first
  • Exact order quantities, not just flags
  • One-click PO generation per supplier
  • Slack integration available on Pro plan
Daily Reorder Alert — Oct 14

"I used to live in spreadsheets trying to figure out when to reorder. With Cadence, I check one email every morning and I'm done. We haven't had a stockout in eight months."

Why Cadence

Not another bloated suite.
One focused tool that does one thing.

Other inventory tools

  • Lead times buried in settings — not the main event
  • Reorder points are manual thresholds, not dynamic calculations
  • Demand forecasting requires hours of configuration
  • Dashboards with 40 metrics, none of them actionable
  • Priced for agencies, overkill for a solo seller with 50 SKUs

Cadence

  • Timing is the product — your reorder date is front and center
  • Dynamic reorder points recalculate daily from real velocity
  • Demand forecasting works on day one, no configuration needed
  • One daily email with the three things you actually need to act on
  • Priced for sellers at $200K–$2M — not enterprise bloat

Pricing

One stockout costs more
