A split shipment is one order despatched as multiple parcels, typically because some items are available now and others are not. It costs more in shipping and generates support contacts from customers who think their order is incomplete. The decision should follow a written rule, because handling the same situation three different ways in a week is what customers notice.
In more detail
Most stores decide this per order, in the moment, by whoever notices. That produces inconsistency, and inconsistency is more damaging than either policy would be on its own, because customers compare experiences and support has to defend a difference nobody intended.
The trade is straightforward once written down. Splitting costs extra shipping and generates a second delivery notification. Holding risks a complaint about the whole order being late. Contacting the customer costs time and sometimes triggers a cancellation.
The rule does not have to be sophisticated. Two variables, delay length and order value, cover almost every case, and having any written rule beats having the theoretically best one applied inconsistently.
Where people get it wrong
- Deciding per order. The inconsistency costs more than either policy.
- Splitting without telling the customer, which reliably generates a where-is-the-rest contact.
- Charging shipping twice for a split you chose to make.
- Not counting the support contact when comparing the cost of splitting against holding.
Common questions
When should I split an order?
By written rule rather than case by case. A workable starting point: split when the delayed item is more than a few days out and the order is above a value floor, hold when it is not.
Does splitting cost more?
Yes, in shipping and usually in support contacts, because a partial delivery generates a where-is-the-rest enquiry unless the customer was told first.
Should the customer choose?
For high-value orders, asking is often worth it. For routine ones the delay of asking usually costs more than either option, which is why a default rule matters.
