Product substitution is offering a customer an alternative item when the one they ordered is unavailable. In wholesale distribution, it is what keeps an order whole when something is out of stock, discontinued or short.
Handled well, substitution protects the sale and keeps the retailer’s shelf filled. Handled badly, it leads to refused deliveries, credits and a buyer who stops trusting what they will receive
When substitution is used
- The ordered item is out of stock
- Only part of the quantity is available
- The product has been discontinued
- A pack size or format is no longer supplied
- The item is restricted for that customer or region
- A comparable item can be delivered sooner
What makes a good substitute
| Factor | What to look for |
|---|---|
| Function | Serves the same purpose for the retailer’s shoppers |
| Size or pack | Similar unit size, or a quantity adjusted to match |
| Price | Close enough that the retailer’s margin holds |
| Brand | Same brand where possible, since shoppers notice |
| Quality tier | Not a visible downgrade |
| Availability | Actually in stock in the quantity needed |
Quantity matters as much as the item. Swapping a 1L bottle for a 500ml one means doubling the units to supply the same volume, which is easy to get wrong.
Approved vs unapproved substitution
Approved substitution means the retailer agreed to the change before delivery, either for that order or through a standing rule set in advance.
Unapproved substitution means the supplier made the swap and hoped it would be accepted. This is a common source of refused deliveries and credits, and it damages trust even when the alternative was sensible.
Many distributors agree substitution preferences with regular accounts in advance, such as which brands are acceptable and whether a smaller pack is allowed. That turns a conversation into a rule and speeds up the order.
Why substitution slows orders down
Substitution needs a decision, and decisions need the retailer. On a manual order desk, that means a rep emails or calls the buyer, waits for a reply, then updates the order. If the buyer is on the shop floor, the order can sit for hours. Orders placed after hours wait until the next day.
The delay, rather than the substitution itself, is usually what costs the sale. Keeping the order, the approval and the amended line in step is part of the wider job of managing sales orders.
Measuring substitution
- Substitution rate: share of order lines substituted
- Acceptance rate: share of proposed substitutes the retailer accepts
- Time to approval: how long it takes to get a decision
- Lost lines: lines cancelled because no substitute was offered
A low acceptance rate usually means the substitutes being chosen are not close enough. A long approval time means the process, not the product, is the problem.
How Ordana helps
Ordana handles substitution without waiting for a rep to be free. When the Ordana Desk Agent validates an order and finds a line that cannot be supplied, it selects a comparable alternative from your catalog, taking size, pack and pricing into account, and contacts the retailer with the suggestion.
The retailer replies through whatever channel they already use, including text and chat, and the agent closes the order once they approve. Where a call is faster, the Ordana Voice Agent rings the buyer instead. The change is recorded in the confirmation, so nothing arrives unannounced. Ordana’s own example shows this full loop, from stockout to approved substitute to closed order, taking nine minutes.

Frequently asked questions
Do you need customer approval to substitute a product?
Yes, unless the customer has already agreed standing substitution rules for their account.
What is a like-for-like substitute?
An alternative that matches the original closely on function, size, quality and price.
How should substitutions be communicated?
Clearly, before delivery, with the original item, the proposed alternative and any price difference stated.
Is substitution better than a backorder?
It depends on the retailer. A substitute fills the shelf now, while a backorder keeps the exact product but arrives later.
