You ordered 10,000. You received 9,870.
On a bulk print job, the quantity that arrives is rarely the exact number on the order. It might be a little more, it might be a little less. For a buyer who has never seen it before, a short delivery looks like a mistake or worse. For a printer, it is a normal part of production, and most printers' terms say so somewhere in the small print.
The industry term is overs and unders. This guide explains why they happen, what a reasonable tolerance looks like, how you are usually charged for them, and how to set the quantity terms on your order so you are never short on the day it matters.
Why the count is never exact
Every bulk print run loses some sheets along the way. The press needs sheets to reach correct colour and registration at the start of the run. Folding, binding and trimming machines need setting up and adjusting, and each adjustment uses up a few copies. Some sheets are pulled for quality checks. A jam in a folder or a stitcher spoils a handful more. Printers plan for this by printing extra, called spoilage or waste allowance, on top of your order.
The trouble is that spoilage is an estimate. On a simple flyer it is predictable. On a job with several finishing steps, such as a saddle-stitched booklet with a gatefold cover and a shrink-wrapped pack, each step adds its own uncertainty. The printer aims for your quantity, and the run ends slightly above or slightly below it.
| Job | Why the count varies |
|---|---|
| Single-sheet flyers | Little finishing; count is usually close |
| Folded leaflets | Folder setup and occasional jams |
| Saddle-stitched booklets | Several sections must match; any spoiled section spoils a copy |
| Perfect-bound books | Binding setup, trimming, and covers and text spoiled separately |
| Die-cut packaging | Die setup, stripping waste, gluing |
| Personalised or numbered items | Each piece is unique, so a spoiled one must be reprinted individually |
What tolerance is normal
Many printers work to a tolerance of a few percent either way for standard commercial work, and some quote larger percentages on short runs of complex products, where a few spoiled copies are a bigger share of the total. There is no single rule in Singapore that sets this. It is a matter of each printer's terms and what you agree on the order.
Read the printer's terms of sale, or ask directly, before you place a bulk order. The questions are simple:
- What tolerance do you work to on this kind of job?
- Will I be charged for overs, and credited for unders?
- Can you guarantee a minimum quantity, and what does that cost?
How overs and unders are charged
There are three common approaches, and the quote should say which applies:
- Charged at run-on rate. You pay for what was delivered. Overs are charged at the low per-copy rate for extra copies, and unders are credited at the same rate. This is common in commercial print.
- Fixed price, quantity approximate. You pay the quoted price whatever the final count, within the tolerance. Simple, but you are carrying the risk of a short delivery.
- Exact quantity guaranteed. The printer prints extra to make sure you get at least your number. Usually this costs a little more, because they plan for higher spoilage, and any copies above your number may or may not be delivered.
Our guide to how bulk print pricing tiers work explains run-on rates, which are also what makes overs cheap and unders worth only a small credit.
When a short delivery is a real problem
For most marketing material, 2% fewer brochures is not noticed. For some jobs it matters a great deal:
- Direct mail to a fixed list. If you have 12,000 addresses, you need 12,000 printed and addressed pieces. Our article on direct mail runs covers the data side.
- Packs for a known headcount. Conference delegate packs, student workbooks and staff handbooks have a fixed number of recipients.
- Regulated or controlled items. Numbered tickets, vouchers and certificates, where every number must exist exactly once.
- Distribution to many branches. If 40 outlets each expect 250 copies, a shortfall means one branch receives none. See our guide to distributing a bulk run to multiple branches.
In these cases, put "minimum quantity" on the purchase order, not just "quantity". It changes how the printer plans the run.
Setting the quantity terms on your order
A clear order removes most disputes before they start. Write these points into the purchase order or confirm them in the quote:
- The quantity and whether it is a minimum. "10,000 minimum" or "10,000, tolerance plus or minus 3%".
- How overs and unders are billed. At the run-on rate, or included in a fixed price.
- Whether you want the overs. Some buyers prefer the printer to keep or recycle overs above a certain number, especially if storage space is tight.
- How the count is confirmed. By carton labels, by weight, or by a counted sample. Ask for the quantity per carton to be printed on each carton label.
- What happens if the count is short. A credit, or a top-up print of the missing copies. A top-up costs the printer a fresh setup, so agree in advance whether it is offered.
Checking the count when the job arrives
Counting 10,000 leaflets by hand is not realistic. Most receivers do three things instead:
- Count the cartons and multiply by the quantity per carton on the labels.
- Open one or two cartons at random and count them, or weigh a counted stack of 100 and compare it with the weight of a full carton.
- Note any shortfall on the delivery order before signing, and tell the printer the same day.
The same receiving check is a good moment to look for transit damage. Our guide to checking a pallet when it arrives lists what else to look for.
Overs worth keeping
Overs are not always a nuisance. On a recurring job, a few hundred extra copies can cover the requests that come in after the main distribution: a branch that ran out early, a sales team that needs samples, or a late addition to a mailing list. Some buyers ask the printer to pack overs in a separate, clearly labelled carton so they do not get mixed into the main distribution and can be stored as a reserve. If you hold reserves like this, record where they are and how many, so the next reorder takes them into account. Our guide to storing a bulk print run explains how to keep spare stock in good condition.
Planning your quantity with tolerance in mind
The simplest protection is to order a little above what you actually need. If you need 10,000 brochures for a mailing and the printer works to a 3% tolerance, ordering 10,300 as a minimum, or 10,500 with normal tolerance, covers the shortfall and leaves a few spares for the office. Our article on forecasting print quantities covers how to arrive at the base number.
Bulk print runs with clear quantity terms
We state the tolerance and the billing method for overs and unders on every bulk quote, and we can guarantee a minimum quantity where your job needs it. Each carton is labelled with its count, and the delivery order shows the total delivered. If you are planning a mailing, a delegate pack or a multi-branch distribution, tell us the exact number you need and we will plan the run around it. See our express printing options for tight timelines, or send your specification through the contact page.
