Replenishment planning: reorder timing, busy seasons and a worked example

The stock emergency usually starts at delivery

Most urgent reorders are not caused by a sudden spike in demand. They are caused by the previous order arriving, being unpacked and then forgotten until shelves or storerooms look thin. By then, the time needed to confirm, produce and ship the next order may already be longer than the stock that remains. After-sales planning closes that gap by setting the next review date as soon as the current order is received.

For international supply, the lead time is made up of several stages: confirming the order and any changes, production, pre-shipment checks and documentation, freight, and clearance and delivery at the destination. Each depends on product, quantity, approvals and production capacity, and the proposal confirms the indicative schedule. Replenishment planning simply makes sure that schedule starts early enough.

Information to collect after every delivery

• Date the order was placed, date it was confirmed and date it arrived, so the real end-to-end lead time is recorded.
• Quantity received against quantity ordered, and any short or damaged units.
• Average weekly usage or sales since the previous delivery.
• Any change in packaging, artwork or specification that will affect the next order.
• Upcoming events that will change demand, such as a hotel opening, seasonal menu or retail promotion.
• Storage limits at your warehouse or site, which cap how much can be received at once.

Setting a reorder point

A reorder point is the stock level at which the next order should be placed. A simple version multiplies expected usage per week by the lead time in weeks, then adds safety stock to cover variation in either. Safety stock is a judgement: higher when usage is volatile or the lead time has varied in the past, lower when storage is tight and demand is steady. The formula is a starting point for discussion with your supplier, not a guarantee of availability.

A hypothetical worked example

For example, imagine a boutique hotel group using a private-label bathroom amenity range. The numbers here are illustrative only. Across its properties, the group uses around 2,000 units of shampoo a week. Based on its own records from previous orders, it plans on a total lead time of 14 weeks from placing an order to receiving it. Usage during lead time is therefore 2,000 multiplied by 14, or 28,000 units.

Because usage varies with occupancy and one past order arrived later than planned, the group adds four weeks of safety stock, or 8,000 units. Its reorder point is 28,000 plus 8,000, which is 36,000 units. When stock on hand and stock already on order falls to 36,000, the group places its next order.

Now add a busy season. The group expects occupancy to lift during a holiday period, raising usage to about 3,000 units a week for eight weeks. If that peak falls inside the lead-time window, the expected usage during the lead time rises. Assuming eight of the 14 weeks are peak weeks, usage becomes (8 × 3,000) + (6 × 2,000), or 36,000 units, and with the same 8,000 units of safety stock the reorder point for that cycle becomes 44,000. The practical lesson is that seasonal reorder points need to be calculated ahead of the season, not during it.

Planning around busy seasons

Busy periods affect both sides of the supply chain. Your demand may rise at the same time as production lines and freight capacity are under pressure from other buyers. A few habits help:

• Share a forecast for the next two to three orders, not just the next one, so production can be planned in advance.
• Confirm artwork or packaging changes well before the order that needs them, since approvals add time.
• Decide early whether a peak order should travel by sea or by air, and ask for both to be quoted if timing is tight.
• Agree whether a larger order or a split shipment suits your storage and cash flow better.

Making replenishment a routine

The discipline is less about the formula and more about the calendar. Record the next review date on the day goods arrive, revisit the reorder point after each delivery using actual lead time and usage, and flag changes to your operations contact as soon as they are known. When working with Klense Supply, the operations contact coordinates samples, production and delivery, so early notice of a forecast change or an upcoming season gives the most room to plan.

Frequently asked questions

How much safety stock should we hold?

It depends on how much your usage and lead times vary and how much storage and cash you can commit. Start with your own history, then adjust after each delivery.

Can a supplier hold stock for us between orders?

That depends on the product and what is agreed in the scope. Raise it during the proposal stage so any arrangement, cost and responsibility is written down.

When should we tell our supplier about a seasonal peak?

As early as you can estimate it. Even an approximate forecast lets the schedule account for development, approvals, production capacity and freight.

Discuss your supply requirements

If your last reorder felt rushed, it is worth planning the next few together. Send an enquiry with your usage, current stock and upcoming seasons, or request a discovery call to work through a replenishment schedule.
