WHAT IS A MINIMUM ORDER QUANTITY?
Minimum order quantities or MOQs are the minimum order size that the supplier is willing to accept. This is often expressed as the minimum number of units. However, suppliers may also set the minimum order quantity in terms of order value. For example, Supplier ABC Ltd will only accept an order in excess of $1000.
As a major constraint, it's important that the minimum order quantities for each product is up to date and correct in the master data. If it is not, this could lead to costly mistakes or avoidable delays when placing the purchase order.
In a perfect world, suppliers would supply the products your business needs in the exact quantity that you need them. More importantly, they would be more than happy to do this at no extra cost.
However, in reality, placing orders with suppliers is far more complex. Given that most suppliers will impose a Minimum Order Quantity, all constraints must be considered before the order is placed.
But what are minimum order quantities? Why do suppliers need to impose such constraints? What impact do MOQs have on your inventory position? More importantly, how can you optimise purchase orders to satisfy order constraints without exposing your business to risk?
WHY DO SUPPLIERS HAVE MINIMUM ORDER QUANTITIES?
While MOQs may price some potential customers out, suppliers still need to ensure that they make a profit. After all, the supplier still has transportation, holding, handling and administration costs to cover. Often these overheads account for a small percentage of the overall value of the order. However, the smaller the order quantity, the more these costs eat into the profit margin.
Take for instance the following scenario:
In scenario A, the supplier makes a healthy profit. However, in scenario B where the customer order quantities are much smaller, the supplier makes no profit at all. Worse still, if the supplier would allow customers to purchase in single units, such as in scenario C, they would actually make a loss on every transaction!
While this is just a simple example, from the supplier’s perspective, selling the products in such small quantities makes no financial sense at all. As a result, suppliers set minimum order quantities to protect their own margins.
WHAT IMPACT DO MINIMUM ORDER QUANTITIES HAVE ON YOUR INVENTORY?
MOQs have a major influence over how many days of stock a business holds as well as how frequently purchase orders are made with suppliers. In the example below, we explore how low MOQs impact the inventory position:
High Minimum order quantity
Where the supplier has a high MOQ in place, the most obvious impact is that inventory has to be held in much higher quantity. At the point of replenishment, the business will hold over 20 weeks of inventory. The consequent of this is that the overall holding costs will be very high such as a large volume of stock will take up a much greater amount of space in the warehouse. More importantly, however, a much higher level of working capital will have to be invested in order to satisfy the MOQ. Consequently, the risk of obsolescence is far greater.
However, the upshot of high MOQs is that the product will not need to be reviewed or ordered as frequently. As a result, administration and ordering costs can be minimised. Furthermore, the risk of stockouts is also very low. After all, the supply chain team has several weeks to respond to any potential availability issue!
Low Minimum order quantity
Low MOQs have a very different impact on inventory. If suppliers are willing to accept a much lower minimum order quantity, businesses can hold a much lower level of inventory and replenish inventory when required. The real benefit here is that a lower investment of working capital is required and the risk obsolescence is reduced significantly.
The danger of ordering lower MOQs is that the product will have to be reviewed and ordered far more frequently. This, of course, comes at a cost in terms of admin and order processing costs.
Unlike with high MOQ where volatility is absorbed by the fact that there is a high level of inventory in the first place, low MOQq will mean that the inventory levels are likely to be leaner. Consequently, low MOQs leave the operation more exposed to spikes in demand and supply issues. To safeguard availability from such factors, it may be necessary to hold a strategic level of safety or buffer stock.
