Why Procurement Teams Struggle With Cost Forecasting (And How Technology Helps)

Procurement Teams

Being part of the procurement team can be hard! That is because you have to forecast figures amid highly volatile key factors. For example, the prices of fuel fluctuate quickly, and shipments are subject to change as well. Due to that, in the end, your bill looks completely different than what you predicted in the first place.        

Procurement costs can change at any moment. It might be helpful to have access to data related to energy commodity prices. But that alone isn’t key to streamlined forecasting.

Hence, to make the process less of a hassle and more accurate, harness the power of technology. Get the key information in such a way that processing it becomes faster and more rewarding.

Why Input Costs Are Unpredictable

When working on a purchase budget, your past input costs are probably a good representation of what you’ll spend going forward.

At least they used to be that way.

There is more than one factor that can change the cost of inputs, such as oil and natural gas. If there are changes to the supply or demand, transportation, or currency, a company could end up paying more or less for their chosen inputs. Supplier costs can also vary; if labor stays the same but input costs go up, a company could expect a revised quote from their suppliers for better decisions.

Depending on how far those prices move up or down, your input costs could change significantly. The World Bank has made a prediction that energy prices would rise 32% in 2026 according to their global energy price index. That’s a forecast for the annual energy-price index, not a final 2026 result or a prediction that every fuel price will go up by 32%. But the point is, if you have an input cost that can change drastically at any moment, it should be noted in your forecast.

Companies may also find that inputs are indirectly attached to energy through the manufacturing of other products.

Why More Detailed Market Prices Aren’t Enough

It can be difficult to forecast spending when you have fluctuating prices scattered between different sources.

Using a commodity data API can pull live prices, as well as past prices, into your tools of choice, allowing for quick market lookups or comparative analysis when forecasting.

One thing to note, however, is that you need to make sure that the price you’re looking at matches your purchased product, unit, area, currency, and day. The market prices couldn’t line up exactly with what your supplier might have charged, which means you’ll want to cross-check these data points.

If you pull in this data and don’t follow these steps, you’ll just forecast inaccurate figures at a faster rate. 

Know What You Will Pay For

If a manufacturer purchases a product, and the price is attached to an energy input, you can expect that price to fluctuate based on market rates. The product’s pricing may be based on last month’s price, or perhaps your supplier is adding additional processing fees, shipping costs, etc. Currency fluctuations can play into your forecasted prices as well. So, be careful! 

Not only should you ask, “How high will my price go in accordance with current trends,” but also, “What price will I pay, and when?”

To help forecast, break down your purchasing cost into its major components. Estimate what you might have to pay by separating market-linked charges, fixed costs, and other variable costs such as shipping and currency effects. Then, use that knowledge to calculate your expected unit price for each commodity, multiply by your estimated quantities, and you can now provide your financial department with a more detailed prediction of the total spending.

If your team is forecasting what you are going to spend and using market prices, but doesn’t account for the differences, that will most probably lead to inaccurate forecasts, even with more detailed market data. 

The Problems With Using A Spreadsheet

Spreadsheets are great, but when you have multiple people updating forecasts on their own, errors are bound to creep in.

Your financial team might be working off of your yearly forecast, procurement might know what your latest vendor quotes are at the moment, and your operation may know how much quantity they plan on producing, but that piece of information hasn’t been updated on your forecast yet.

Each department knows some aspects of what they’re going to spend, but none of them know all of the details completely.

Manual price updates can bring about outdated or incorrect figures, and some errors may remain unnoticed until a purchase order or invoice is prepared. A shared system with clear data ownership and checks can decrease inconsistencies and help teams spot errors faster.

Use Scenarios To Forecast Spending

You won’t know for sure what your input costs are going to be, so use technology that allows you to create various scenarios to plan out spending. Below are some ways to start using scenarios to forecast spending on energy-tied products in a better way.

  1. Understand what areas or factors will impact your pricing, i.e., commodities, suppliers, contracts, etc.
  2. Research the prices that will correspond with those areas; be cautious that the information you find matches what your supplier is using for their operations.
  3. Design scenarios with increased and decreased energy prices, keeping quantities consistent, unless you are trying to test if that will impact your spending.
  4. Learn what time frame the prices are applied to; are they tied to the price the next day, or is there a lead time that can be used, or shipping delays that need to be factored into your forecast well in advance. 
  5. By comparing the difference between your forecast, quotes, and invoiced costs, you can learn where your discrepancy is, whether it be shipping, quantity, or a market fluctuation.

Allowing for different scenarios will help your forecast evolve, not only giving you one number to predict spending, but showing you where those changes have come from. As long as you understand your scenarios, you won’t expect one specific price, but know you’re doing everything possible to create a detailed forecast to pass on to your financial team.

Technology Won’t Do It All

Technology can collect market observations, maintain historical records, and produce or update forecasts, but users still need to check the inputs, assumptions, and results.

You’ll want to monitor these markets, understand the different data sources, and learn when they apply to your scenario.

You can also have alerts created so that when your forecasted energy input reaches a certain dollar amount, a notification will be sent, and your pricing is recalculated. That will save a lot of time and energy. 

AI tools can already assist with scenario calculations and forecasts, but trustworthy results still depend on verified historical observations, suitable assumptions, and human review.

Stay On Top Of Your Forecasts

Develop habits that allow you to monitor your costs. Learn the cycle your vendors operate on, when prices can increase, or when they reset, etc. By comparing your forecasts to what you were actually charged later on, you can understand if you need to change your model or learn more about the products you are purchasing to forecast more effectively.

The aim is to understand how possible price changes could affect future purchases so your team can respond faster.

FAQs

Ans: It is the practice of predicting future demand, supply requirements, and market pricing for goods and services, in short.

Ans: That is because key components of the cost depend on highly volatile variables. Due to that, costs keep changing, often making the approximations fail and increase inaccuracy in final figures.

Ans:These are for Control, Consolidation, and Compliance.
