Promotional product overruns and underruns describe delivery quantities above or below the amount ordered. For a custom squishy campaign, that difference can affect the invoice, event allocation, and number of complete giveaway packs.
A quotation for 1,000 pieces does not, by itself, tell you whether exactly 1,000 acceptable finished units will arrive. Confirm the quantity terms before approving production, especially when every recipient needs the same branded item.

Separate the Order Quantity From the Required Quantity
Start discussions about promotional product overruns and underruns with the number of usable units the campaign actually needs.
Suppose an event has 1,000 confirmed recipients. An illustrative 1,000-piece order with an agreed 5% underrun could deliver 950 pieces. Paying for fewer units would not solve the missing 50 giveaways.
That percentage is a hypothetical example, not an industry standard or a Vilora policy.
Tell the supplier whether your number is a target, a minimum acceptable delivery, or an exact requirement. Ask whether the proposed product and production process can meet it. Ordering extra is a separate purchasing decision, not a substitute for understanding the terms.
Our Bulk Event Giveaway Toys guide covers scheduling around the required arrival date.
Ask What the Supplier Actually Allows
Policies on promotional product overruns and underruns differ between suppliers.
Hit Promotional Products publishes an overrun and underrun allowance and states that exact-quantity orders are unavailable under its listed terms. By contrast, 4imprint’s FAQ says it does not charge customers for overruns and charges for the received quantity if an order ships short.
These examples show why buyers need to read the actual quotation and order confirmation. Neither policy establishes the conditions for another supplier.
For a proposed squishy order, ask whether any tolerance applies, whether an exact quantity is available, and whether a minimum delivery can be confirmed. Get the answer in writing before production starts.
Define the Quantity by Design and Artwork
Promotional product overruns and underruns become more complicated when the order contains multiple versions.
Imagine 1,000 squishies split between two event locations, each requiring 500 with its own logo. Receiving 520 of one version and 480 of the other still totals 1,000. It does not meet both locations’ needs.
Specify quantities separately where the distinction matters: artwork, color, shape, individual package, or delivery destination. Ask whether any allowance applies to each line or only to the order total.

For sets, define a complete pack. If each recipient needs one yellow and one blue squishy, extra yellow units cannot make up for missing blue ones.
The Mixed-SKU Squishy Toy Wholesale guide explains how assortment ratios and packing configurations should be recorded.
Clarify Billing and Acceptance Separately
When reviewing promotional product overruns and underruns, separate permission to ship a quantity from permission to bill for it.
Ask which units are chargeable and whether any permitted quantity change affects decoration charges, packaging, freight, or the order total. Do not assume every charge changes proportionally with the piece count.
Quantity tolerance also should not blur the agreed quality requirements. Confirm how units with unacceptable printing, damaged packaging, or other agreed defects will be counted and handled.
A small difference in the final bill can be manageable. A delivery that leaves an event short of complete, usable giveaways creates a different problem.
Put the Agreed Limits Into the Order Confirmation
Record promotional product overruns and underruns alongside the approved quantities, rather than leaving them in a separate email thread.
| Item | What to confirm |
|---|---|
| Required units | Target, minimum delivery, or exact quantity |
| Quantity allowance | Agreed upper and lower limits, if any |
| Application | Per SKU, artwork, color, set, or total order |
| Billing | Chargeable quantity and related charges |
| Short delivery | Notification and agreed next steps |
| Final count | Packing list breakdown by approved version |
Ask when the supplier expects to confirm the final packed quantity. For a dated campaign, discuss what happens if a shortage is identified too late for another production run.
When contacting Vilora about a custom squishy project, include recipient counts and the quantity needed for each version. Request confirmation of the applicable terms; do not assume exact-quantity supply or free extras.
Clear terms for promotional product overruns and underruns help buyers connect production quantities with the campaign’s actual needs. Agree on what can arrive, what can be billed, and how exceptions will be handled before approving the order.
