Stock cover and incoming supply: practical guide
This guide explains how to use the Count.ie stock cover and incoming supply. Check how long unreserved stock lasts and whether replenishment arrives in time. Follow the inputs, method and worked example below, then compare your own scenario.
Guide written .
Open the Stock cover and incoming supply calculatorWhat to prepare
- Gather order history, item dimensions, weights and supplier lead times.
- Identify the same units and planning period across stock, demand and capacity inputs.
- Check which freight, storage, import or production costs the model includes.
Understand the inputs
The calculation method
Available stock = on hand − reserved. Cover days = available stock ÷ demand; projected gap compares demand to delivery time.
Worked example
Illustrative inputs and their result.
Example inputs
- Stock units on hand
- 1000
- Reserved stock units
- 100
- Average daily demand
- 50
- Units arriving in next delivery
- 500
- Days until incoming delivery
- 15
Calculated example result
- Days Of Cover
- 18
- Expected Gap Units
- 0
- Incoming Arrives Before Stockout
- Yes
How to interpret the result
A capacity, inventory or landed-cost estimate is not a guarantee of service availability. Variability in demand, lead time, packing and customs treatment can change the operating result.
Keep the service requirement fixed while testing demand, lead time or shipment size. Check practical constraints such as handling, access and supplier minimum quantities separately.
Common mistakes to avoid
- Do not mix usable capacity with nominal capacity.
- Keep net goods weight separate from packaged or shipping weight.
- Do not treat a supplier's usual lead time as a guaranteed maximum.
Assumptions and sources
Incoming stock contributes to total cover, but cannot prevent an earlier stockout if it arrives too late.
