Inventory runway for Amazon sellers

Know your days out before stock runs out.

DaysOut shows how many days each SKU really has left by combining sell-through, inbound shipments, supplier lead times, and Amazon receiving lag so you can reorder before stockouts cost rank, ads, and revenue.

Planning intelligence

See true runway before it becomes a stockout.

DaysOut turns scattered inventory reports into a clear priority list: what will run out, when to reorder, and how much margin you really have before rank, ads, and revenue take the hit.

Inventory runway

See true days out at the SKU level.

DaysOut converts sell-through, reserved inventory, inbound timing, and supplier lead times into an actual days-out view so Amazon sellers know when they need to act.

Inventory signals

Know where the risk is forming.

DaysOut replaces the spreadsheet guesswork with a live inventory control surface built for the decisions Amazon sellers make every week.

Velocity analytics

Surface risk before the stockout window closes

See when velocity spikes, ads compress runway, and receiving delays erase your buffer faster than the unit count suggests.

Inventory dashboard

See every ASIN on one screen

Your entire catalog in a single view — days remaining, velocity trends, inbound status, and alert states so you can spot the problem before it becomes a stockout.

Risk signals

Act on signals, not spreadsheets

DaysOut surfaces the risk signals that matter — velocity spikes, receiving delays, ad-driven burn — so you can act while there is still time to protect rank and revenue.

How it works

From inventory noise to reorder action.

01

Connect the seller data

Bring in inventory, sell-through, inbound shipments, and supplier timing across the SKUs that matter.

02

See which SKUs are truly at risk

DaysOut turns scattered reports into a days-out view that reflects real Amazon inventory behavior.

03

Reorder before rank and ads take the hit

Act while there is still time to place the PO, slow spend, expedite, or rebalance before stock goes dark.

Use cases

Built for the moments that cost you rank, revenue, and sleep.

Every week, Amazon sellers face decisions where a few days of visibility make the difference between protecting rank and watching it collapse.

Best seller at risk

A top ASIN has 12 days left and the next PO will miss check-in.

DaysOut makes the runway visible early enough to cut ad spend, move inventory, or expedite.

Catalog planning

One parent listing is healthy, but two child ASINs will stock out first.

See variant-level risk before the best seller drags the whole listing into trouble.

Seasonality and PPC are burning faster than last month.

Model the shorter runway before promos, Prime peaks, or new traffic push coverage below safe levels.

Testimonials

The proof is in the operators.

Trusted by founders, inventory planners, supply-chain leads, and marketplace operators who manage stock risk every week.

Canvas Commerce

DaysOut made FBA receiving lag visible in the same place as sell-through. That changed when we place POs, not just what we order.

Nina Foster Inventory Planner

Forge Beauty

We now know which ASINs can survive a promo and which ones need protection. The tradeoffs are finally obvious.

Atlas Wellness

It cut our stockout review from a long spreadsheet meeting to ten minutes. We know exactly what needs attention first.

Samir Dutta COO

Bramble Kids

The catalog view is what sold us. One glance and we can see where safety buffer is disappearing across marketplaces.
