The continual reduction of costs in the supply chain is a top priority for supply chain managers. The trick is think of it less as a cost cutting exercise and more as a strategic job: the funds being saved should propel differentiation, like free shipping or loyalty programs, which in turn open up new cost cutting opportunities.
Well, normally that’s the case. Since we are in a pandemic, simply having more cash on hand is critical for most companies too. No one wants to make layoffs, and COGS likely aren’t going down, so trimming costs along the supply chain is the next high-impact bucket.
What follows are 4 cost-cutting ideas that might work for different companies in different situations. They are based from my experience at Amazon during past crises, or from what peers much smarter than me have shared.
Everyone is hurting right now, including logistics behemoths like UPS, FedEx, USPS, and DHL. They need the volume.
Right now is the time to go back to the contract, and ask about renegotiating to find better terms.
Your leverage will depend on which of these three brackets fit you over the next 6 months:
My biggest piece of advice with carriers is to understand that there is no unilateral “best rate” to be found. No carrier has the best rate for all situations.
Consequently, we typically advise holding contracts with multiple carriers so you can make use of algorithmic decision making to always pick the cheapest and fastest option. It’s even more beneficial to consider that right now. All carriers are starving for volume, which gives you a little more leverage today than you might have had yesterday in securing cheaper rate tables.
So, the main tip: Explore adding multiple carrier contracts in addition to renegotiating with your existing carrier if you only have one on hand.
Here are some additional considerations:
A lot of factors go into placing a purchase order. The biggest factors include forecasted demand, vendor lead time, and order frequency. These factors all get mixed together into a probabilistic soup to produce an order quantity. This process can be automated or manual, but the calculation must ultimately consider how much you can control all of these factors when arriving at an order quantity.
Based on what you can and can’t control, here is a tip that is counter-intuitive: You will actually save more money by increasing your inbound cost-per-unit.
Let’s breakdown what that means by digging into these factors with a little more detail:
Like most logistics puzzles, you benefit most by putting energy into what you can control. Given the reality of the world right now it is very unlikely that demand or lead time will be predictable. That is why right now is the perfect time to look at increasing your order frequency to give yourself more opportunities to change your decision.
The best way to explain is with a simple example. You will have other complexities, but let’s keep it simple to illustrate the basic principles.
For this example I’m going to assume you are doing a normal best practice of monthly procurement to get a volume discount and lower cost-per-unit on shipping. The order is based on a normal projected demand of 100 units per week for this hot product. The vendor lead time is typically four weeks.
Except it turns out that demand has really dropped because of the global pandemic. There is uncertainty everywhere. A couple days after the order is placed it becomes clear that you are no longer going to sell 100 units a week but you have already placed the order and 400 are on the way.
Now you will exit next month with 280 extra units of inventory. The type of inventory will determine the severity of the miss (bananas vs. batteries, for example). From a modeling point of view, however, the excess inventory added risk to the business because you tied up cash in assets that aren’t usable. Right now cash is more valuable than inventory.
Instead, think about de-prioritizing volume discounts and increasing order frequency to something closer to a weekly cadence.
Let's look at what would have happened in this scenario if you were on a weekly order cycle.
In this scenario you would have ordered only 100 units to cover Week 5 in your first order because you know that you will get a chance to order more next week for Week 6. Just like above, you place your order for 100 units and then immediately realize that demand is dropping. You order 20 additional units in Week 2 instead of 100. Forecast continues to drop so in Week 3 and 4 you don’t place an order at all.
When the demand is uncertain like it is right now it is important to focus on levers that you can pull to give you additional flexibility, in particular the levers that help improve your cash position. The price breaks from placing monthly orders will land a huge amount of overstock. The smaller cost-per-unit amount wasn’t worth the cash flow problems you created.
While reducing the size of the orders will increase your inbound cost-per-unit, it gives you the flexibility to adjust to demand fluctuations which is a great way to improve your cash position.
Here is another counter-intuitive move that might eat into immediate cash reserves, but produce stronger cash flow in a short amount of time with a fast turn around, thus strengthening your mid-term balance sheet if you have the cash available today to do so.
The topic is economic ordering.
Economic ordering is a larger topic but it’s worth diving into because of the rapidly changing economics of the world today due to the pandemic.
At a high level, economic ordering is deciding how much inventory to buy based on maximizing economic outcomes like profit or revenue. The calculus involves all factors that affect the profitability of the transaction: COGS, fulfillment cost, the sale price, whether it gets marked down, etc. The actual calculus depends on the specifics of your business.
There are generally two main approaches to buying economics.
The first is a budget-based approach where the total spend for a buying cycle is managed through a top-down buying process. It is what traditional S&OP does. Basically, demand forecasting informs budget scope which informs what to buy. This works well in situations where demand across SKUs is predictable because shoppers are predictable. For example, if a customer buys a winter coat from your site they will likely not buy another winter coat this season.
The second approach is a bottoms-up approach that looks at each SKU independently and decides how much inventory to buy based on the specific demand and profitability of that SKU. This is mostly what we did at Amazon because each SKU was relatively independent. For example, just because a customer bought a Nespresso does not mean the consumer will buy coffee cups too. Bottoms-up is usually an independent exercise for every SKU, but in reality cash flow and warehouse space constraints often override the pureness of the exercise. I want to focus on the bottoms-up approach for this discussion.
Top-down is easier to isolate demand stability per customer profile, while bottoms-up is easier to isolate demand stability per SKU.
Bottoms-up ordering when conditions are stable is interesting because, if all factors are stable, the actual calculation is not very interesting at all. Imagine the scenario where I have stable customer demand and the purchase price for the item is locked into an agreement with a vendor who won’t go out of business. The math ends up being straightforward because the purchase timing isn’t changing (no advantage to buying early) and if I buy too much I’ll just sell it next week (no risk of markdown).
But things are not so stable right now.
The first obvious observation about the current state of the world's ecommerce supply chain is where demand is outstripping supply. Goods that fight COVID-19 are the strongest example as hand sanitizer and face masks are out of stock everywhere. There are lots of categories where this is the case (hair grooming products!), and the knock-on effects up the supply chain into manufacturers and suppliers will reverberate into your supply chain too.
The second observation is that this has introduced an immediate opportunity for price gouging because of our old friend scarcity pricing. Similar price inflation can float up the supply chain and is one way to feel the reverberations.
It turns out that the converse is also true but we don’t pay as much attention to it because it doesn’t represent an immediate business problem like price gouging from a supplier. Specifically, demand patterns have changed enough with goods where demand is not outstripping supply that there is excess inventory in all stages of the e-commerce supply chain. Anytime this happens, some portion of manufacturers and suppliers will want to offload their excess supply now to increase their cash flow.
It goes without saying that right now is probably an excellent time to look for discounted inventory if you have the cash. Heavy discounts on product cost will almost always outweigh holding cost even if it is for several months.
The conundrum is whether to spend the cash now or not.
How playing offense factors into improving your cash position depends on turnaround time related to the economic purchase. If your business has fast turnaround times, then you will see the profit gains quickly, with the extra profit hitting the balance sheet fast enough to strengthen your cash position in a way that didn’t create much risk for your business. If you have very long turnaround times from when you would make an economic purchase, then you might want to consider whether or not spending the cash now on opportunistic discounts is worth it.
If you are one of those manufacturers, suppliers, or retailers who has excess inventory, I also caution you to be careful about marking down inventory too quickly.
Using the same principle as above, the cost of holding inventory for a couple extra months is going to be small in comparison to heavily marking the item down now to sell it.
Businesses always have strain because of cash flow but if you can weather the storm you will be in a much better position when things clear up.
If possible, look for other angles to boost cash reserves first, and think of liquidating excess inventory as one of the last resorts.
This is a situation many will likely face in summer due to the bullwhip affect, which is different than the situations you faced at the beginning of the pandemic in March.
Consumer predictability has been erratic at best, so short-term forecasting has been difficult. A surge in demand for a certain product has or will quickly dissipated for many companies.
The result is "overstock" — a frustrating scenario for supply chain managers.
There are ways to handle overstocks to generate either quick or sustainable cash flows. The methods come with a caveat however. They aren't a universal solution, but potential tools to use if
Let's establish a few assumptions so you can determine if your company and situation is a fit.
→ Let's assume you believe the overstock will still have some demand, just on a longer time horizon. It's not dead stock.
→ Let's assume you are comfortable tolerating the stowage costs, and desire to sell the stock at full price. No discounting.
→ And let's assume you have more than one FC.
If this is the case, then reallocation of overstock based on geographical projections will save you major basis points in margin.
Reallocation is often a tough pill to swallow, though, because of the upfront costs to ship a truckload cross-country. It's an underutilized tactic.
The key insight stems from the fact that outbound shipping from FC to final destination is one of the most expensive operational expenses. It can be as high as 70% of total logistics COGS, depending on the makeup of your business.
Subsequently, saving a big chunk of 70% shipment-over-shipment more than makes up the difference of the painful decision to pay to send an FTL shipment between FCs.
A simple model:
In this specific pandemic overstock scenario, you should consider that you are potentially overstocked at the FC level and not in a macro sense. Meaning, eventually the stock will sell, but maybe it's selling better in west zones than east zones, so your east FC is constantly sending long-haul shipments to customers. That's what we call a margin eater!
Instead, look at historical purchasing patterns and make an educated projection on future sales of the remaining overstock. You might find reallocation to be a strong way to improve cash flow as the overstock slowly sells.
Some companies might be facing the prospects that they overestimated demand and the way the pandemic has played out has resulted in severe overstock of something they feel might not ever sell.
That's a tough situation to be in.
In this scenario, the calculus comes down to two measurements:
(A) Either you take the hit by paying for a warehouse expansion to stow the goods in hopes of eventual sale.
(B) Or you take the hit in margin by liquidating the goods via resellers.
I'm normally a proponent for ecommerce companies to consider liquidation as a last-resort idea. Most of the time the math works out to hold onto stock and eventually sell it at full price (or at least not pennies on the dollar).
But these aren't normal times.
In this case, ecommerce liquidators are a boon for a few reasons:
