p
- Package Acceptance PendingA carrier tracking status indicating a shipping label exists or the parcel has been presented, but the carrier has not recorded the initial acceptance scan. The item may be at a drop off counter, pickup location, or in a container awaiting its first scan, so tracking shows only pre shipment details. The status updates to accepted or received once the first physical scan is recorded.
- Packaging CertificationA documented approval that a packaging design meets specified standards or regulations for transport, handling, and storage. It is granted after testing or audit against criteria such as drop, vibration, compression, environmental exposure, or hazardous materials performance. Programs include ISTA transit tests, UN markings for dangerous goods, and retailer or carrier requirements that define packout and labeling. Certificates state the tested configuration, limits of use, test lab, date, and reference method.
- Packaging EngineeringThe discipline that designs, specifies, and validates containers and packing systems to protect products during handling, storage, and transport. Scope includes material and structural design, manufacturability, line and warehouse fit, labeling, and regulatory compliance such as food contact and dangerous goods. Activities include lab testing like drop, vibration, compression, and environmental conditioning, plus evaluation of cost, recyclability, and carrier requirements.
- Packaging OptimizationA structured process that improves pack design, materials, and unitization to meet protection, cost, and handling goals across storage and transport. Work typically covers right sizing cartons, selecting cushioning or insulation, setting case pack and inner pack counts, and designing pallet patterns to raise cube utilization and lower dimensional weight charges. Validation uses lab tests and line trials with metrics such as damage rate, cost per shipment, material use, pack time, recyclability, and conformance to carrier, retailer, and regulatory requirements.
- Packing SlipA document placed in or on a shipment that lists the items sent and their quantities. It typically includes order and shipment identifiers, destination and return addresses, carton count, SKU or part numbers, item descriptions, and notes such as lot or serial numbers. Receivers use it to verify contents and record discrepancies. It is not an invoice and does not request payment.
- Pallet ConfigurationThe specified arrangement of cases or items on a pallet, including case pattern per layer, number of layers, orientation, and whether layers are column stacked or interlocked. It also defines pallet size, allowable overhang, total height and weight, load stabilization such as stretch wrap or banding, and any labeling or footprint limits. Documented pallet configurations standardize unit loads so they fit handling equipment, storage racks, and receiver or carrier requirements.
- Pallet ExchangeA shipping practice in which pallets used to deliver or collect freight are swapped for pallets of the same type and quality at pickup or delivery. The arrangement keeps pallet ownership and inventory balanced between trading partners. Exchange terms specify pallet standard such as size and grade, one to one counts, who inspects and documents, and how shortages, damage, or nonconforming pallets are charged.
- Pallet PoolingA shared pallet supply model in which shippers rent standardized pallets from a pool operator instead of owning them. The operator retains ownership, inspects and repairs pallets, tracks movements, and redistributes inventory across the network. Participants pay per issue and return, with charges for loss or damage, and follow specified return points and quality standards. Pooling standardizes pallet specifications across trading partners and replaces one way pallet exchange programs.
- Pallet RackingA steel storage system for palletized goods, built from upright frames, beams, and bracing to form bays with multiple vertical levels accessed by forklifts. Common configurations include selective, double deep, drive in and drive through, push back, pallet flow, and mobile. Specification and safe use rely on rated capacities, pallet dimensions, aisle width, lift truck type, anchoring, decking, and applicable fire and seismic codes.
- Parcel ConsolidationThe practice of combining multiple small parcels into a larger shipment such as a master carton, pallet, or truckload for transport to a regional hub. At the hub the shipment is broken down and individual parcels are entered into parcel carrier networks for final delivery. The process uses destination based grouping, container and piece level labels, and a single manifest to manage routing, tracking, and billing.
- Parcel ForwardingA service in which a third party receives parcels at an assigned address, logs and stores them for a defined period, prepares required shipping paperwork, and reships them to a specified destination. Providers may consolidate multiple parcels into one shipment, repackage, relabel, and complete customs declarations. Charges usually cover handling, storage, and outbound carrier postage.
- Parcel Invoice AuditA systematic review of parcel carrier invoices to confirm billed charges match contract terms and shipment data. The audit checks base rates, zones, dimensional weight calculations, fuel and accessorial fees, address corrections, residential and delivery area surcharges, minimum charges, and duplicate billing. It also verifies service level performance for potential late delivery credits, flags exceptions, submits disputes to carriers, and reconciles credits to the account and general ledger.
- Parcel ShippingTransportation of individual packages that meet carrier size and weight limits, moved through collection, sorting hubs, and final delivery to the recipient. It uses standardized labels with tracking barcodes, service levels such as ground and air, zone based rating, dimensional weight pricing, and published surcharges and minimum charges. Core steps include pickup scheduling, manifesting, tendering to carriers, tracking events, delivery confirmation, returns handling, and claims processing for loss or damage.
- Perpetual InventoryA record keeping method that updates item quantities and valuation as each transaction occurs. Movements captured include receipts, picks, returns, transfers, and adjustments recorded through systems such as WMS, ERP, point of sale, barcode or RFID scans. The ledger maintains stock on hand by location and, when used, by lot or serial, and applies costing methods such as FIFO, LIFO, or weighted average. Accuracy is maintained with cycle counting and exception review rather than relying solely on scheduled full physical counts.
- Perpetual Inventory SystemA method and supporting software that updates inventory quantity and valuation continuously as each transaction is recorded. It captures receipts, picks, returns, transfers, and adjustments through inputs from WMS, ERP, point of sale, barcode, or RFID. Records keep on hand balances by site and location and, when used, by lot or serial, and apply costing such as FIFO, LIFO, or weighted average with audit trails and timestamps. It uses cycle counting and exception review and differs from a periodic system that updates only at set intervals.
- Pick AccuracyThe warehouse metric that measures how many items were picked correctly compared with the pick list. Calculated as correct picks divided by total picks times 100. Errors counted typically include wrong SKU, wrong quantity, missing items, or picks from the wrong location.
- Pick and PackAn order fulfillment process in which warehouse staff retrieve items from storage to fill a customer order, then pack them for shipment. Tasks typically include following a pick list or scanner prompts, locating SKUs, confirming quantities with barcode scans, consolidating items, selecting a carton or mailer, adding dunnage or inserts, and applying the shipping label and paperwork. Common execution methods include single order picking, batch or cluster picking, and zone picking, after which cartons move to manifesting and carrier handoff.
- Pick To LightA warehouse picking method that uses light modules with numeric displays mounted at storage locations to direct workers to the correct SKU and indicate the quantity to pick. The worker confirms each pick by pressing a button or scanning at the light, which records the transaction in a warehouse management system or dedicated controller. Installations are typically arranged on shelving or flow racks and support workflows such as batch picking, zone picking, and put wall operations.
- Picking Accuracy RateA warehouse metric that measures the share of picks completed without error. Calculated as correct picks or lines divided by total picks or lines, multiplied by 100 percent. Errors include wrong item, wrong quantity, wrong location, or missing item. Reported by unit, line, order, or time period to compare performance across teams, processes, or systems.
- Picking MethodologyThe set of rules and processes a warehouse uses to plan and execute order picking. It covers how orders are released, how items are grouped, the routes workers follow, and the tools used to direct and confirm picks. Common approaches include discrete picking for a single order, batch or cluster picking for multiple orders in one trip, zone picking with later consolidation, and goods to person workflows where automation presents items to the worker. Methods can run in waves or be released continuously and may use RF scanners, voice systems, pick to light, or autonomous robots to capture transactions and track accuracy.
- Pod Proof of DeliveryDocumentation that verifies a shipment was delivered to the consignee. It may be a signed paper receipt or an electronic record. Standard fields include shipment ID or tracking number, delivery date and time, recipient name and signature, driver ID, delivery address, and item counts. Some systems add barcode scans, GPS coordinates, or photos. Carriers and shippers use PODs to confirm delivery, trigger invoicing, resolve claims, and meet contractual or regulatory requirements.
- Pool DistributionA regional delivery method that consolidates many shipments into one linehaul move to a pool point near the destination, where freight is deconsolidated and dispatched for local delivery to multiple consignees. The workflow includes origin consolidation, linehaul, destination cross dock, sort by consignee or store, and final mile delivery. Programs rely on consistent carton labeling, a shipping manifest, and scheduled receiving times. It differs from less than truckload service by using a single long haul with many short local runs inside a defined area.
- Port of EntryA government designated location where people, goods, and vehicles legally enter a country or customs territory. Officials there conduct customs and immigration processing, inspect cargo and documents, assess duties and taxes, apply import restrictions, and authorize release. Examples include seaports, airports, land border crossings, rail terminals, and inland ports with customs offices or bonded facilities.
- Predictive ShippingA logistics method that uses demand forecasts to stage inventory or begin fulfillment before a customer places an order. Models draw on order history, product attributes, customer location, and transit times to predict what will be needed and where. Execution may include pre allocation of stock, pre printing labels, or moving items to forward nodes or carrier hubs so an order can be finalized on confirmation. It relies on real time data exchange among commerce, warehouse, and carrier systems and defined rules for cancellations, returns, and billing.
- Pro Forma InvoiceA preliminary document issued before shipment that states a seller’s quote and intended terms for a specific order. It lists the parties, goods description, quantities, unit and total prices, currency, weights and dimensions, HS codes, delivery terms such as Incoterms, expected ship date, and a validity period. It is used to request import licenses, begin customs clearance, and support bank or letter of credit applications, but it is not a tax invoice and not a request for payment. A commercial invoice replaces it once the goods ship.
- Product LiquidationThe process of converting excess, obsolete, returned, or distressed inventory to cash through secondary sales. Common channels include bulk sale to liquidators, auctions, closeout brokers, and off price retailers. Activities typically include setting eligibility rules, grading condition, creating lots and manifests, debranding or destruction when required, and transferring title under as is terms. Financial handling may involve write downs and removal of the items from available stock records.
- Product SegmentationThe practice of dividing a product portfolio into defined groups using shared attributes such as demand pattern, margin, size and handling needs, risk classification, life cycle stage, or regulatory status. The segments provide rules for planning and execution, for example service levels, safety stock targets, replenishment methods, assortment by channel, or transportation mode. In warehouse operations it can guide slotting, storage conditions, packaging standards, and picking methods. Segmentation criteria and segment assignments are recorded and maintained in master data.
- Public WarehouseA third party storage facility that serves multiple clients on a fee for use basis. Space and labor are charged by pallet position, cubic footage, weight, or time. Services commonly include receiving, putaway, inventory control, order picking, packing, cross docking, and shipment staging. Operators issue warehouse receipts, hold goods under bailment, and maintain stated liability through a tariff or contract. Some locations also provide bonded storage for customs controlled goods.
