Warehouse management systems (WMS) are widely used in larger organisations where stock and order volumes demand a high-level of control. However, in smaller companies, where stock turn and order volumes might be lower, much of the same problems are experienced when handling ‘physical stock’. Therefore, is a WMS about high-levels of control or just the way to do things properly, and is it something that businesses of any size could use?
The usual route for a growing company is to perceive a need for ‘stock control’ at a certain stage of its development. Software modules that provide it are often a component of accounts systems or, in the e-retail sector, online selling solutions. Most businesses need accounts and order capture so there is a logical step to using the stock or inventory solutions that come with them.
What these systems do in many cases is OK. If you do not hold the stock yourself you may only need a numeric stock total in order to advise availability to your customers. If you hold your own stock but work with smaller quantities and order volumes such a solution may also be adequate. But as your business expands the problem of relying on a system for stock accuracy that does not control stock in the physical sense – or is not linked to one that does – becomes bigger.
That is one reason why larger companies nearly always consider WMS to be essential. The other reasons are for operational efficiency. As you expand, hold more stock, and process higher numbers of orders, the level of operational control you need to do so efficiently increases. This is where the control offered by WMS – based on system instruction, verification of stock transactions, and increasingly, real time movement updates – becomes the only true form of ‘stock control’. In other words, these businesses need to know not just how much stock they have but also other information such as where it is located, whether it is accessible, how old it is, its weight and size, and more.
So what stops smaller businesses embracing the WMS system? Clearly cost has been a deterrent in the past, with little available in the market for the smaller company. But now, cloud-hosted systems such as ProSKU are available by monthly subscription, which makes them accessible to a wide range of companies. The monthly cost of use can represent a minimal sum compared with total labour and operating expenses, and requires little cost justification in the traditional sense.
It would be wrong to say ROI does not matter, but it is of less concern than with capital projects. A capital spend involves cash outlay, so a decision to invest in software rather than other business areas needs to be justified. You need to know when you will get your money back! A service-based solution on the other hand need only be justified to the extent of its minimum term. This can de-risk the exercise, enabling benefits to be realised, or assessed, at low cost.
The potential upheaval to implement a WMS system also deters smaller businesses. But now, with no need to install big infrastructure, manage servers, or administer a database, things are much simpler. Systems developed specifically for the cloud with the latest web technology and API functionality mean fewer integration issues. In ProSKU’s case we have used experience of larger company projects to refine set-up processes and perfect a system genuinely accessible to the smaller user.
So does a WMS pay for itself in the smaller company? People often say: “We’ve only two people in the warehouse, it wouldn’t give us any benefit.” I disagree. Even with just two people you will see some savings. They will not be huge, as the cost of using a system is higher as a proportion of labour cost. But based on expected improvements, savings become significant at around four warehouse employees, when annual efficiency gains would equate in value to around one staff member.
As staff numbers hit double figures, you could expect savings of around GB£45,000 – GB£50,000 per year, or two to three staff members, based on employee costs of GB£7.50 per hour, plus minimum on-costs. Bear in mind this is probably a cautious estimate. The number of factors you can improve by using a WMS and their knock-on business effects mean you could see considerably greater benefits. In the end, what value do you put on customer satisfaction and retention?
