12 to 36 Month Inventory ReStocking and Cash Flow Planning Excel Tool

Inventory is difficult to work with as far as financial modeling and logic building go. This new tool is more of a cash management planner in order to help you know how much cash you need in order to keep up with your product sales forecast. You will also see the amount of reserve/buffer available over time for each SKU.

Three files are included (one for startups, one for ongoing operations, and a separate reorder tracker). The files can be downloaded immediately after purchase. This is included in the inventory template bundle and the Accounting Templates in Excel bundle.

NOTE, when you download the zip, the V3 versions are the 500 SKU large files, and the V2 versions are the smaller 19 SKU versions. They both work the same and the only difference is the SKU count. You can always cut the 500 SKU versions down be removing rows you don't need, for example using only 100 SKU slots or 50 or what have you will lighten those up.

The hardest part of building this model was how to dynamically account for different lead times for different SKU types. I did figure it out so you will see that based on the amount of inventory purchased at each re-order and the number of days it takes for an order to actually reach your inventory, it will show you the timing of when different SKU's need to be purchased and the cash that it takes month to month.

This is important because oftentimes you have to buy ahead of planned demand. The way the 12-month forecast works will take your average sales counts during each month of the year for the past 3 years and then based on a % increase/decrease you enter, it will give you the forecasted unit sales per SKU for the next 12 months. That logic accounts for seasonality factors that cause more or less sales to happen at different times of the year. You need to know how that impacts cash flow.

The cash management then comes into play as it will show the timing of when things need to be bought in order for you to have enough supply for the planned demand. That is huge as the assumptions can cause dramatic fluxes in how much cash you need and when. Often times this is not accounted for precisely and shortages can occur that are hard to fix because of various logistical problems.

The model will aggregate all the data into one monthly cash flow line. For added visibility, you can also see the total sales per your forecasted unit sales counts. This is a really good tool to implement with your other models that may not take into account the nuances of inventory cash requirements over the course of a year. This tool can plug right into your other models as it shows the data on an aggregate monthly basis.
