Download White Paper: Ecommerce and Omnichannel Supply Chain Management

What retailers, distributors and manufacturers must know

So You are, or Want to Begin Selling Online

The purpose of this white paper is to give you a complete picture of ecommerce and omnichannel supply chain design. It will help you with the decisions you need to make when considering how to participate in the ecommerce economy. Some key decisions are highlighted in italics.

First, What is Omnichannel?

If you are getting into ecommerce, you need to know about omnichannel as it is the current and future wave of how retailers, distributors and manufacturers will sell online.

Omnichannel is the logistics system that leverages all assets to fulfill in-person and online (ecommerce) orders. Omnichannel companies use stores, warehouse locations, and the inventory in both, to improve customer service by delivering quickly, while maximizing profit. The key omnichannel decision is “how you will fulfill online orders to take advantage of all assets in a network.”

Optimizing Tradeoffs of Omnichannel Ecommerce Fulfillment

Tell a businessperson that they will need to deal with a tradeoff, and they will typically see it as a negative. However, tradeoffs represent an optimization opportunity. The tradeoffs you need to be aware of in omnichannel fulfillment is speed of delivery (and subsequent market share) versus inventory + facility cost.

More Fulfillment Locations = Faster Delivery and Higher Market Share

Speed in online order fulfillment is the critical design criteria for omnichannel companies. The percentage of customers who want same-day or next day delivery without paying a premium is growing. In our research we have found that speed directly translates into market share. Figure 1 shows ecommerce market share based on speed of delivery for a sporting goods omnichannel retailer [1].

More Fulfillment Locations = Higher Costs

Being closer to customers and delivering online orders faster means shipping from more locations, including stores, branches and warehouses. However, the more locations you use, the more complexity you add to your business processes. The simplest, and most labor-efficient option to fulfill an order is to use warehouses. However, they may be far away from customers. Stores are close to customers but they are not set up for efficient picking, often have inventory inaccuracies and do not have space for packing/shipping online orders.

Your job is to balance speed and market share versus costs to maximize your ecommerce profit.

Making these Decisions with Growing Online Demand

Online demand is experiencing a steady increase of its share of total retail and wholesale sales. Because it is still in a growth phase, retailers, distributors and manufacturers need to make decisions about omnichannel logistics without knowing when online demand growth will slow. Will online demand grow to 100% of sales and stores become obsolete? In 2020 online sales soared due to the COVID-19 pandemic. However, will it plateau as people visit stores again, or grow… and how fast? Companies must model different scenarios and make the best possible decision given this uncertainty.

Choosing an Omnichannel Network Design: SFW, SFS, SFWSB, SFW+S

There are four omnichannel fulfillment designs.

  • Ship-from-warehouse (SFW) uses warehouses that both replenish stores and fulfills online demand. SFW is the simplest omnichannel fulfillment design because centralization creates economies of scale.
  • Ship-from-store (SFS) uses brick-and-mortar stores to fulfill online demand. The advantage of using stores is greater inventory utilization and proximity to customers.
  • Ship-from-warehouse-with-store-backhaul (SFWSB) looks at the inventory across stores and warehouses that are in the same market as one inventory. If an item for an online order is in the store, that item is backhauled to the warehouse where all online orders are fulfilled. SFWSB’s advantage is combining the simplicity of SFW with greater inventory availability.
  • SFW+S allocates the online order to the location that is closest to the customer and has the inventory needed on-hand. SFW+S requires a robust order allocation system and rules of how much to use stores versus warehouses, the importance of distance and inventory minimums.

A graphic of each channel design is shown below.

You need to choose one of these designs for your online order fulfillment.

Other Trends You Need to Know about in Ecommerce Fulfillment

Buy-Online-Pickup-In-Store (BOPS): A Customer Inventory Reservation System

In the last few years Wal-Mart and others have implemented BOPS. This saves people the work of shopping and saves the retailer the expense of shipping the order. However, the real benefit of this system to consumers seems to be as an inventory reservation system. People use it to reserve an item in a store to ensure it is on-hand, so they don’t have the hassle of an item being stocked-out when they go to the store.

If you’re a distributor, this has a name, “will-call.” If you are a retailer you need to think about the tradeoffs of giving this convenience to your customers versus the increasing costs and complexities of your own people picking items off shelves as customers are in the store doing the same thing.

Dark Stores

An interesting strategy, as less people shop in brick-and-mortar stores, is for companies to convert their retail (light) stores to mini-warehouses that can fulfill online orders or serve as BOPS locations. Dark stores allow retailers, or pure ecommerce companies, keep an assortment of high-velocity items very close to customers for same-day delivery. The light stores are converted into dense storage and picking layouts, so they are more efficient and have lower operating costs due to their less desirable locations. As with much of ecommerce, Amazon started this strategy by purchasing closed K- Marts and converted them to dark stores.

I think soon, grocery retailers and many other companies selling a wide merchandise assortment are going to set up dark stores or convert light to dark stores. This is a tough decision that requires detailed cost versus benefit modeling.

Next Day, then Same Day, now Next Hour Shipping

A supply chain researcher once said that “the internet killed distance then mobile brought it back.” Back when ecommerce first arose, no one cared where the warehouse was located. However, when people started shopping on their phones, suddenly there was a need for immediate satisfaction. Ecommerce supply chain strategies are now focused on fulfilling orders with same day or even same hour delivery. Amazon teased us with the potential for drone deliveries from their warehouses. This seems to have been premature but the need to provide immediate delivery is a problem all companies need to solve.

Ultra-fast delivery could be the great advantage of having stores or branches. They are already close to customers and form an inventory and delivery network.

Again, this is a tough decision that requires detailed cost versus benefit modeling. What will you gain in market share? Or will you just make existing sales cost more for you to fulfill because existing customers switch to same day when they don’t need this service?

Order Allocation/Assignment (distributed order management)

Another problem that needs to be solved when implementing omnichannel supply chain is what site to use to fulfill an individual order. A simple algorithm is to use the closest location to the customer. Because it is simple, it is also fast and can be done almost immediately after receiving the order. However, it has been shown to be ineffective because of inventory considerations. Would you ship from a site that is closer if you were taking the last item out of the store or ship from a site is farther way that has more inventory? What about the probability of multiple items on a single order and the potential for costly split shipments (shipping one order from multiple locations) – would this affect your order allocation decision? Instead, a model that considers all of these issues, and is fast, is needed to optimize both customer experience and cost.

You need to consider distributed order management software to automate this complex decision.

Omnichannel Warehouse Operations

In the “good old days” warehouses were designed for specific functions. They either processed pallets or packages. However, for a retailer to have two warehouses that are designed for each specific function causes extra inventory and doubles facility costs. Instead, companies are designing omnichannel warehouses that blend full pallet, mixed pallet and package operations in one facility. This requires innovative layouts, sophisticated processes and use of different types of equipment including forktrucks, reach-trucks, stock-pickers, vertical lift modules and other robotics.

There is a cost to having many different types of warehouse operations in one facility. But it is the way most omnichannel companies are headed because it is lower total cost than building dedicated facilities.

Omnichannel for Manufacturers and Distributors

An important new topic is omnichannel for manufacturers and industrial distributors. Instead of having to put a store on Amazon, or using Amazon for fulfillment, manufacturers and their industrial distributors are teaming up to create a network of warehouses and branches that can fulfill online orders quickly and efficiently. I don’t think either a manufacturer or distributor can “go it alone” in the battle against Amazon. Manufacturers control the product and brand, and have a global view of demand. Distributors, with their warehouses and (possibly more importantly) branches can provide same-day delivery in focused geographies.

Manufacturers need to set up agreements on profit-sharing in a different way than traditional wholesaling so they get broad geographic coverage of their products, at a deeper level than wholesalers (distributors) may be willing to carry. Distributors need to shift from a model where they only deliver large items and have customers pick up smaller items from their branch to an efficient pick/pack/ship operation at all facilities.

Significant and difficult changes will be required for manufacturers and distributors to embrace omnichannel. However, the alternative is for Amazon to own the customer supply chain.

“Mitch Millstein and his team helped guide our shop fabrication division in the re-layout of our custom pipe and steel fabrication facility when we moved into a new building. It is not only the results but how he helped. We were involved in every step. I personally did time studies and was able to see the non-value added steps required to manufacture in our old layout. When we created our new layout, everyone was involved, from the executive team to our direct labor force. With Mitch’s help we increased our throughput by a 3x multiple, while providing more competitive prices to our clients as a result of the efficiency improvements.

This has enabled us to not only make more money but also to expand our commercial reach and serve more, and larger customers. I would recommend Supply Velocity to any company that wants to make improvement in supply chain and operations.”

Geoff Gross, President, Gross Mechanical
“In 2015 we began working with Dr. Mitch Millstein to optimize our inventory locations supporting e-commerce and in-store inventory needs. From this work we developed a new omni-channel warehousing and inventory plan that entirely redefined our approach to warehousing, inventory management, store distribution and fulfillment. As a result of the analyses by Dr. Millstein we have begun the move to an improved omni-channel design by reassigning MSAs to new warehouses, greater leveraging of in-store inventories to satisfy e-commerce demands, and exploring acquisitions of new warehousing space in strategic locations. We have already seen an improvement of $300,000 from both more efficient shipping strategies due to better inventory management.”
Rob Bowers, Vice President of Strategy, Total Hockey
“In the spring of 2003, the St. Louis Area Chapter of the American Red Cross engaged Supply Velocity, Inc. to perform a study and make recommendations to streamline office processes, maximize cash flow in purchasing and warehousing and restructure and enhance our maintenance department. Supply Velocity, Inc.’s process was methodical, flexible, staff-oriented, inclusive and, above all, trackable.

In the last six months, our Chapter has realized expense savings of over $380,000 annually, and significant improvement in intra-company service levels has been attained. Supply Velocity, Inc. will return to the Chapter periodically throughout the next 18 months to audit our newly implemented processes.

“In thirty years of hiring consultants, Supply Velocity, Inc. was the first to tell me what they were going to do, set a price they stuck to and substantially exceed my expectations. I have recommended them to friends and acquaintances. They were true partners in assisting with the turnaround of an acquisition we had been struggling with for two years.

Their math-based technology, solid down-to-earth facilitation skills, and positive, patient and enthusiastic attitude combined to make our implementation of Lean a very rewarding experience.

We increased our production by 50% in the first month of implementation and continue to see improvements. Improvements have not only been realized in productivity, but also in quality and morale. We have increased profitability by $2M on flat sales of $10M.

Based on Supply Velocity, Inc.’s integrity and our results, I will continue to refer them to others and utilize them in the future as we expand our company through acquisitions.”

“Supply Velocity has helped Clean succeed in a number of ways. First, they provided the education that kicked off our Lean Process Improvement journey. They also facilitated a number of large supply chain and process improvement projects including: 1) building quality into our direct-labor productivity incentive program, 2) designing the layout of our garment warehouse, and 3) streamlining our route service process.

We have integrated the methods that Supply Velocity taught us into our management and strategic planning. In the process our quality measurement has improved 22% from 2013 to 2015, we have reduced required annual labor by 2200 hours from the garment facility layout project and we’ve seen 50% decrease in error rate. Obviously the numbers speak for themselves, but just as important, Supply Velocity has been fun to work and have become true partners. They have “taught us how to fish” so our internal teams are able to implement change on their own, with the skills we learned from Supply Velocity. This relationship has been invaluable.”

Jeff Lazaroff, Senior Vice President, Clean Uniform
“We engaged with Supply Velocity to help us embed process improvement at all levels of the business. Our team learned from Mitch to let the data drive decisions, to use Lean tools to help us see our processes critically and objectively, and to create a control plan to manage all of the tasks that were the outcome of the data study.

The project turned out to be very significant to the company and most importantly, our customers. We reduced our customer wait times by 40%, and cut in half the labor cost to fulfill customer orders.

Some results are not able to be measured. However, as a result of this project, we have started to build a Lean mindset and culture, which is part of our strategic mission to save our customers money. Supply Velocity has been a valued partner in this mission.”

Dionne Dumitru, COO, Weekends Only
“The role of the Erie Insurance Marketing Department has been evolving over the past several years – from a support role to a more critical role of driving growth in our organization. Because of our increased workload and desire to prioritize the most critical projects, we hired Supply Velocity to teach us the skills of Lean Six Sigma.

Participants included the Promotions, Market Research and Agency Licensing sections of the Marketing Department.

We learned valuable tools to help us to prioritize based on the voice of the customer.

I firmly believe these skills made a difference in how we work every day. We are moving new projects forward, eliminating or changing ineffective processes, and we are a much stronger department. We continue to use the tools to help us with our highly-complex and time-consuming projects. Supply Velocity helped us to accomplish our goals.”

“Myerson engaged Supply Velocity, specifically Ray Davis to visit our plant in Trinidad to conduct a two day assessment of our production procedures and provide us feedback on areas for improvement and where applicable, areas for future analysis.

Put simply, we got everything we paid for and in addition to more in depth analysis, we got specific tasks that were immediately actionable. Our local management team found Ray to be engaging, highly credible and insightful based on his wide experience. In other words the cultural differences and lack of specific industry knowledge weren’t impediments to things we could implement immediately and on our own. In a nutshell it was money well spent and will pay itself back many times over.”
