Prime Big Deal Days can put a lot of pressure on an e-commerce operation in a very short space of time. Naturally, there's the stock to think about, along with packaging, warehouse space, and whether there’s enough capacity to deal with the orders coming in - but the preparation for events like this goes a little bit further than that.
If you already know certain products are likely to be popular, that shouldn’t be news to the warehouse when the orders start landing. A good 3PL should be working with brands on forecasting ahead of events like Prime Big Deal Days, using expected demand to plan stock, space, labour and picking capacity before the pressure arrives.
That becomes particularly important when a product that normally shifts a few hundred units a week suddenly sells a few thousand in 24 hours. Stock moves faster, picking priorities can change, and the warehouse may need to rethink where products are positioned. With the right forecasting and communication in place, those decisions can be made before the rush rather than in the middle of it.
At TSP Fulfilment, forecasting is part of that wider partnership. The aim isn’t simply to receive a forecast and hope it holds up. Working with brands to understand what’s coming means the operation can prepare for changes in demand, flag potential pressure points and make sensible decisions before they become urgent problems.
That’s where communication really matters during a big sales event. When the brand and 3PL are working from the same plan, there’s far more opportunity to move stock, adjust priorities and make sure capacity is in the right place. It’s when that communication breaks down that the little things can become rather less little: a change in plan doesn’t make it to the warehouse, stock isn’t where the system says it is, or someone assumes someone else has already dealt with it.
Then there are the returns. They won’t necessarily come straight away, but they’re still part of what happens after those 48 hours. Orders have gone out, customers receive them, and some will eventually make their way back to the warehouse. Having a clear process in place for those returns helps keep everything running smoothly once the Prime rush is over, rather than leaving the warehouse to work it out afterwards.
The best preparation is often in the details. Know which lines are likely to cause the biggest rush, make sure they’re easy for the warehouse team to get to, agree what happens if stock starts running low, and work out how returns will be handled before they arrive. Those decisions are much easier to make before the first wave of orders hits than when everyone is already trying to keep up, including the bits nobody thought to put on the spreadsheet.
