Keep four quantities separate.
The ordered quantity is the commercial request. The produced quantity is what comes off the manufacturing route before every finishing and quality step is complete. The accepted quantity is the usable stock after the agreed checks. The delivered quantity is what reaches the named destination. An invoiced quantity may follow the order, the accepted delivery or another written basis. Those numbers need not be treated as synonyms.
An overrun means more acceptable finished units than the nominal order; an underrun means fewer. Neither word supplies a percentage, price rule or permission by itself. Trade practices, processes and supplier terms differ. Ask for the permitted range, the invoicing basis and the treatment of excess or short supply to be stated in the quotation.
The print-run planning notes address demand and stockholding. Quantity tolerance is a different decision: it deals with what may be delivered against the placed order after production has been planned.
Explain when exact quantity has a real job.
A numbered edition, one kit per delegate, regulated pack count or matched set may need an exact usable quantity. Say why. The production route may require extra printed components so that losses during cutting, binding, collating or packing do not leave the final set short. Exact delivery can therefore change the amount produced, the controls used and the price.
Other projects can accept a sensible written range. A campaign team may prefer additional leaflets if they are usable, while a small warehouse may not want unplanned cartons. The decision is commercial as well as technical. Define whether extras are welcome, billable, free, capped, held, recycled or excluded; do not let the delivery team invent the answer. Where serials, access codes or regulated identifiers are involved, say whether unused numbers must be reconciled or destroyed and who records that outcome. Keep that control separate from the acceptable physical overrun, because an extra printed shell may not be an authorised active item.
Versioned work makes one total misleading.
Imagine 6,000 brochures split across English, French and German versions. A tolerance applied to the combined run does not necessarily protect the quantity required in each language. Record the ordered and minimum acceptable count per version. The same applies to packaging SKUs, numbered cards, regional catalogues and any set in which one missing component limits the whole usable quantity.
Keep version labels unambiguous throughout production and packing. The version and data planning route helps separate shared artwork from changing content, while the kit and collation checks show why component counts must reconcile at set level.
Destination splits add another layer. If 2,000 copies go to one warehouse and 3,000 to events, say whether an allowed quantity difference applies to the whole order or each allocation. A dispatch note cannot fix a quantity rule that was never agreed.
Reconcile the delivery while the evidence is intact.
At receipt, count cartons, check the stated units per carton and retain labels or packing records long enough to reconcile the shipment. A carton count is useful only when the pack quantity is known. If a shortage, duplicate version or mixed carton appears, record what was received before stock is distributed across a team. Photograph any damaged or relabelled carton before opening it, because the outer evidence may explain a later count discrepancy.
Compare the delivered count with the accepted quotation and order, not with an early estimate. If the quantity sits outside the agreed range, notify the supplier using the project reference and evidence. The delivery and issue route explains why the next step depends on the accepted specification and facts rather than an automatic defect decision.
