There is a relationship between Finance and the Supply Chain in almost any company. The Supply Chain has a majority of the assets of the company and is responsible for managing the lions share of the costs. The assets include factories, warehouses, and all the equipment and machines used in this facilities. The costs include the Cost of Goods Sold, labor, conversion costs, transportation, and distribution costs. When we add to all of this the value of the inventory being held, it is easy to see why Finance focuses on the Supply Chain.
It is the role of the Supply Chain to effectively and continuously manage the above mentioned assets and costs to help deliver the profit goals of the company. It is the role of Finance to ensure that exactly this happens. Finance accomplishes this by a mixture of partnering with and policing the Supply Chain. Finance prepares reports, briefs senior management, and oversees audits both internal and external to ensure that the company is being properly managed financially.
We have seen and experienced situations where Finance and the Supply Chain form a team and work together to achieve the company objectives. We have seen other companies where the relationship is more adversarial and Finance basically plays the role of a policeman. This often has to do with the culture of the organization and the personalities of the two executives leading the functions. It is in the power of the President or CEO of the business to nurture either partnership or adversity between Finance and the Supply Chain. There are CEOs that believe a little adversity, butting of heads, is good and the resulting course of action is more optimal for the vigorous debating.
Either way, it is imperative for the Supply Chain to understand exactly how finance views and calculates inventory. Let us look at few financial definitions regarding inventory management. While it might seem odd when first reading this, it is true. The Supply Chain does not have full control over the inventory as reported. When it comes to reporting, the Finance reports are what senior management and Wall Street tend to look at. Therefore, it is imperative for Supply Chain personnel to fully understand some basic Finance definitions.
There are two ways of recording and reporting inventory: Perpetual and Periodic.
Perpetual: This is the real time reporting, the day to day, hour to hour, reporting of what is on-hand in terms of Raw, Pack, WIP, Finished Goods, E&O, and what is in transit in each of these categories. Because of the sophistication of ERP systems, we can look at perpetual inventory levels in total, by part, and category any time we wish from any PC in the company. This inventory, these records and transactions, is what Supply Chain personnel deal with all the time. It is the inventory that is tangible and real. You can go out to the factory or warehouse floor and see this inventory.
Periodic: As the name suggests, this is the periodic reporting of inventory. This is more the space Finance controls. The most common periods are months, quarters, and fiscal years. This is less about transaction records and much more about reporting. The periodic reports are the official reports of the company. They are based on the perpetual inventory at a set close point e.g. 11:59 pm of the last day of the month. If this was all Periodic inventory was about, there would be no difference between what the Supply Chain sees and manages and what Finance reports. This is rarely the case. Finance takes this base data and makes adjustments and accruals. They add and subtract dollars, not units, to inventory accounts to fund or account for things such as scrapping obsolete goods, returns, warranty related transactions, in transits at the end of the period, and a variety of other bookkeeping details. This does impact the inventory levels positively or negatively depending on the nature of the adjustments. Supply Chain personnel need to know exactly how since these final numbers are what the inventory objectives of the company are set on.
Many companies use the term Consolidated instead of Periodic. Finance takes the Perpetual view at the end of a Period and “consolidates” all of the reserves, accruals, and other adjustments. We prefer the term Consolidated to Periodic.
The Supply Chain lives in the Perpetual world. Yet, the Supply Chain is measured against Consolidated objectives. Therefore, it is imperative that the Supply Chain be bilingual. We must know what we can control which is the Perpetual inventory. But, we must know what happens in month end Consolidations. The Supply Chain leaders need to know exactly what is consolidated at month end to better manage the Perpetual. They must also know how and why reserves, accruals, and adjustments are made and why. If a policy is flawed or will have a long term negative impact on operations, we can better advocate for a more balanced policy. Finance and General Management can and do use inventory as a cistern, sometimes, for costs that are in a gray zone from a Supply Chain perspective. The business decision may supersede Supply Chain logic, but at least we know what is being done and why. At least, we can make a good knowledgeable case for the Supply Chain point of view.
