This article details the information displayed in the Vendor Price Analysis dashboard, and a guide on using this functionality in order to understand the ‘opportunity cost/gain’ of purchasing products from different Vendors within a specific date range, where product prices are not fixed.
The Vendor Price Analysis tab compares the receiving price of a product in base units (per kg/litre/gal/lb), against the median price paid for that product within a specific date range. For example, if apples were purchased as per following Purchase Orders
PO_001: 10kg @ $3/kg
PO_002 3kg @ $4/kg
PO_003 5kg @$5/kg
The median price per unit is $4/kg (middle price).
This means that when the same apples were purchased at $3/kg, a saving of $3*10kg = $30 was made. Similarly, when they were purchased at $5, an overspend of $5*5 = $25 was made.
In this example, overall, a net saving of $5 was made in the month as the total value of product bought below the median price exceeds the total value of product bought above the median price.
Paid +/- Median Base Price Trend
Shown in the top-left of the page, this graph is pre-set with monthly data for the last 24 months. It shows the net (overall) difference for each month in terms of product prices paid against the median for that month.
Small variations to 0 indicate little opportunity between various purchase options, whilst large variations indicate potential savings (black label, below zero) / over-spends (red label, above zero) between various purchase options.
Fig.1 – Paid +/- Median Base Price Trend
The graphic shown in Fig.2 is displayed on the top right of the page (KPI panel). It indicates the lower total (in green) against median price paid, and higher total (red) against median price paid, along with the total net (orange box) for the chosen time period.
In the example in Fig.2, savings made were greater than costs incurred, producing a net overall saving for the month of 5,286, where overall volumes of products were purchased for less than the median price for the period.

Total Savings / Overspend Trend
These graphs show the breakdown of the net result in the Median Base Price Trend graph (shown on the top left of the page) between less paid (left) and more paid (right).
From the Median Base Price Trend graph (see Fig.1), the net saving for Jan 2016 was 354. The Total Savings Trend graph show that in Jan 2016 4,163 was saved (left), and from the Overspend graph in Jan 2016, 3,809 was overspent (right).

Top 10 Savings / Overspend by Vendor & Property
These graph show Vendors and Properties with the highest variances between receiving/paid price, and the Median price for the chosen time period.
Fig.4 - Top 10 Savings / Overspend by Vendor & Property
Top 10 Savings / Overspend by Product
This shows the 10 products with largest net variance to median base price.
The size of the sphere indicates the amount saved/overspent – a large sphere indicates highest overspend, a small sphere highest saving.
The graph also shows the volume received (horizontal axis) and net receiving value (vertical axis).
Hover over each bubble to see the relevant figures – the example in Fig.5 shows that a saving was made of £120 on 18.15 litres of Rapeseed Oil

Saving / Overspend by Vendor Category
This report highlights, per category, the amount purchased from each Vendor and saving/overspend incurred. The example in Fig.6 shows that £97 more was paid on Fish & Seafood when purchasing same products from Johnny Winter.

Using the Dashboard
In order to identify the opportunity for overspend or saving within the example category of dairy products for the last 3 months:
First choose the required time period using the Date Dimension (Business day) filter under Property Details
Within the Product details filters, set the Category filter as required
The Paid +/-Median Base Price graphic (shown in the top right of the page) will show if there is a significant difference in pricing being made, and the trend graph will indicate if this has also been the case historically
Small values in each of these graphics indicate there is little opportunity either due to minor price fluctuations or low volume of purchases, while high values indicate greater opportunity
The Total Savings Trend and Total Overspend Trend graphs will indicate if net movements are both positive and negative swings
The Top 10 Savings / Overspend by Vendor will show which Vendors are driving this, and the Top 10 Savings / Overspend by Property will indicate which properties have the most opportunity
Refer to the Top 10 Overspend / Savings by Product to determine which products have had the largest variations
Then reference these products on the Vendor Price Comparison table to see if the price variation was because products were purchased from a different Vendor. If so, it may be preferable to restrict purchasing to a certain Vendor to prevent overspend or facilitate savings
If Vendor has remained the same, it will indicate a price change by the Vendor
