I Produce Both D2C and Corporate Candle Orders — How Do I Schedule Production When an Unexpected 2,000-Piece Bulk Order Arrives During Normal Monthly Demand?

The order and the month it lands in

Picture a normal month: 3,000 D2C candles of 200 g across your range. That is 600 kg of scented wax, 552 kg of wax and 48 kg of oil at 8%, and at 48 good candles per 10 kg load it is 63 loads. Then a corporate enquiry arrives for 2,000 pieces of a 150 g candle in one scent.

Work out the corporate order first. Each 150 g candle holds 138 g of wax and 12 g of oil at an 8% load on total weight. 2,000 of them is 300 kg of scented wax: 276 kg of wax and 24 kg of oil. A 10 kg load fills 66 candles of 150 g, and about 63 after 5% wastage, so 2,000 ÷ 63 is 31.7 and you plan 32 loads: 294.4 kg of wax and 25.6 kg of oil.

So the month now asks for 95 loads instead of 63, a jump of about half, arriving with a deadline you did not choose. The question is whether your unit can deliver that without the D2C side running dry, and by when.

Check capacity at every stage, not just the melter

Use your own measured figures here. As an example, suppose your unit reliably completes six 10 kg loads a day over 24 working days, which is 144 loads a month. On melter capacity alone, 95 loads fits with room to spare. That is exactly why melter capacity is the wrong place to stop checking.

The shelf-space arithmetic

Shelf space deserves its own sum because it is the stage most often missed. In a corporate week of the example schedule, 16 D2C loads make about 768 candles and 16 corporate loads make about 1,008, so roughly 1,776 candles come off the pouring line in six days, close to 300 a day. Every one of them needs a level, draught-free place to set and then wait until it is ready to pack. Multiply the daily figure by the number of days your candles stay on the shelf, and compare it with the jars your shelving actually holds. If the answer is larger, the shelves, not the melter, set the pace of the corporate blocks.

If the corporate candle is a new format, such as a different jar size, it needs a wick and burn test before production. A 150 g candle is not a 200 g candle poured shorter; the diameter may differ, and so may the wick it needs. Build that test into the plan rather than discovering the answer on candle 400.

Protect D2C before scheduling anything else

The most common mistake is to treat the corporate order as the priority and let D2C fill whatever is left. It feels right because the corporate order is large and has a deadline. But D2C is your repeating income, and stock-outs on your bestsellers during a corporate run cost more than they appear to.

Fix a weekly D2C minimum before you schedule a single corporate load. At 63 D2C loads a month, that is about 16 loads a week. Write those loads into the calendar first. Corporate loads go only into the time that is left, and they do not borrow from the D2C loads when they run behind.

The spare column matters as much as the others. Four spare loads a week during the corporate blocks is your cushion for a D2C spike or a failed batch. Scheduling every last load removes the cushion and turns one problem into a missed deadline. Week four is deliberately light on pouring because the corporate candles are being packed and the team is needed there.

Reserve raw materials for the order

A corporate client expects all 2,000 candles to match. The easiest way to support that is to reserve the order's materials as a set before production starts: wax from as few lots as possible, the full quantity of oil from one lot, and all jars from one supplier batch. Label them for the order and keep them apart from D2C stock, so the D2C team does not use them on a busy day.

Keep one retained candle and a small sealed sample of the oil lot from the corporate run. If the client reorders next year, or raises a query months later, you will have something concrete to compare against rather than a memory of how the order smelled.

Tell the D2C side of the business what is happening, too. If whoever handles online orders knows that the corporate blocks run in weeks two and three, they can hold back promotions on the scents most affected and avoid promising fast dispatch on those weeks. A short note on the production board is enough; the point is that nobody discovers the corporate order through an empty shelf.

Quote a dispatch date from the slowest stage

Once the stage check is done, the dispatch date comes from the slowest stage, not the fastest. Add up the days for materials and sample approval, the corporate production blocks, the time candles need on the shelf before packing, packing itself at your measured rate for the corporate format, and a buffer. Quote that date, and not a day earlier.

If the numbers do not fit, you still have options short of refusing. Offer a split delivery, a later date or a simpler packing format. A clear, honest date that you meet is worth more to a corporate buyer than a fast date you miss, and it protects the D2C customers who keep your unit running every other month.
