Partial Shipment / Backordered Quantity: Flexible Order Fulfillment in Procurement Management
March 30, 2026
Partial delivery/backorder quantity refers to the splitting of an order into several separate deliveries, whereby available quantities are delivered first and missing quantities are delivered later. This practice enables companies to maintain production and bridge supply bottlenecks flexibly. Below, learn what partial delivery/backorder quantity means, which methods are used, and how to successfully manage risks.
Key Facts
- Enables continuous production despite supply bottlenecks
- Reduces tied-up capital through staggered goods deliveries
- Requires precise documentation and tracking of outstanding quantities
- May cause additional logistics costs due to multiple deliveries
- Important tool for increasing supply chain flexibility

Definition: Partial Delivery/Backorder Quantity – Meaning in Procurement
Partial delivery/backorder quantity describes a delivery process in which an originally ordered total quantity is handled in several separate shipments.
Basic Characteristics and Distinction
A partial delivery exists when the supplier can deliver only part of the ordered quantity on the agreed date. The remaining backorder quantity is delivered at a later point in time. This differs from planned Delivery Schedule Release, which are scheduled from the outset.
- Unplanned split due to availability problems
- Separate delivery notes and invoicing possible
- Documentation of outstanding backorder quantities required
Partial Delivery vs. Complete Delivery
While complete deliveries process the entire Purchase Order in one shipment, partial deliveries offer greater flexibility in the event of supply bottlenecks. The Goods Receipt becomes more complex as a result, since multiple receipts must be managed.
Importance of Partial Delivery/Backorder Quantity in Procurement
In strategic procurement, partial delivery serves as a risk minimization tool. It makes it possible to maintain critical production processes while increasing supply chain flexibility at the same time, without having to carry out a complete Purchase Order Cancellation.
Methods and Procedures
The successful handling of partial deliveries requires structured processes and clear agreements between procurement and suppliers.
Contract Design and Agreements
Rules for partial deliveries should already be defined during contract design. This includes minimum delivery quantities, tolerance ranges, and cost allocation for additional transport costs.
- Definition of minimum delivery quantities per partial shipment
- Agreement on delivery tolerances and replenishment deadlines
- Regulation of cost responsibility for multiple transports
Documentation and Tracking
Complete Document Review is essential for managing backorder quantities. Modern ERP systems support the automatic recording and monitoring of open items.
- Separate recording of each partial delivery in the system
- Automatic calculation and display of backorder quantities
- Deadline monitoring for outstanding replenishment deliveries
Communication and Escalation
For critical backorder quantities, defined Escalation Process should apply. Regular coordination with suppliers and internal stakeholders ensures transparent communication about delivery status and expected replenishment dates.
KPIs for Managing Partial Deliveries/Backorder Quantities
Systematic measurement and evaluation of partial deliveries enables continuous optimization of procurement processes.
Delivery Performance KPIs
The partial delivery rate measures the share of incomplete deliveries in the total number of orders. A low rate indicates reliable suppliers, while high values signal a need for optimization.
- Partial delivery rate = (Number of partial deliveries / Total number of orders) × 100
- Average replenishment lead time for backorder quantities
- Degree of completeness of the initial delivery
Cost Analysis and Efficiency
The additional costs caused by partial deliveries are determined by comparing the actual logistics costs with the costs of a complete delivery. These Procurement KPIs are incorporated into supplier evaluation.
Process Quality and Compliance
The backorder tracking rate measures how completely open items are documented and tracked. High values indicate efficient processes and reduce the risk of forgotten replenishment deliveries or duplicate orders in the Purchase Requisition (PR).
Risk Factors and Controls for Partial Deliveries/Backorder Quantities
Partial deliveries involve specific risks that can be minimized through suitable control mechanisms and preventive measures.
Operational Risks and Cost Traps
Multiple deliveries cause additional logistics costs and increase administrative effort. Incomplete deliveries can cause production stoppages if critical components are missing.
- Higher transport costs due to multiple deliveries
- Additional administrative effort for backorder tracking
- Risk of production interruptions for critical parts
Quality and Compliance Risks
With staggered deliveries, quality differences may occur between batches. Goods Receipt with QA Inspection becomes more complex because each partial delivery must be inspected separately.
Contractual Legal Protection
Unclear agreements on partial deliveries can lead to legal disputes. Precise contract clauses and documented Complaint Notice in the event of delivery delays create legal certainty and enable appropriate responses to breaches of contract.

Practical Example
An automotive supplier orders 10,000 screws for series production. Due to a machine failure, the supplier can deliver only 6,000 units on the agreed date. The remaining quantity of 4,000 screws is announced for the following week. The company accepts the partial delivery because the available quantity is sufficient for three production days.
- Immediate recording of the partial delivery in the ERP system
- Automatic creation of a follow-up order for the backorder quantity
- Deadline monitoring and escalation in the event of a delay in the replenishment delivery
Current Developments and Impacts
Digitalization and changing market conditions significantly influence the handling of partial deliveries and backorder quantities.
Digital Transparency and Tracking
Modern track-and-trace systems enable real-time monitoring of partial deliveries. IoT sensors and digital delivery notes create full transparency regarding the status of backorder quantities and expected replenishment dates.
- Automatic notifications in the event of delivery delays
- Real-time dashboard for open backorder quantities
- Integration into supply chain management systems
AI-Supported Forecasts and Optimization
Artificial intelligence analyzes historical delivery data and forecasts probabilities for partial deliveries. Machine learning algorithms optimize order quantities and timing to minimize the risk of backorder quantities.
Sustainability Aspects
Environmental awareness leads to a critical view of multiple transports in partial deliveries. Companies develop strategies to consolidate shipments and prefer suppliers with sustainable logistics concepts for Order Processing.
Conclusion
Partial delivery/backorder quantity is an important flexibility tool in modern procurement management. Through structured processes and clear agreements, the benefits can be leveraged while risks are minimized. Digitalization offers new possibilities for transparent tracking and optimized management of partial deliveries. Successful companies integrate these practices strategically into their supply chain.
FAQ
What is the difference between partial delivery and call-off delivery?
Partial deliveries arise unexpectedly due to supply bottlenecks, whereas call-off deliveries are scheduled and planned from the outset. In the case of partial deliveries, an originally complete order is split, while in call-offs delivery takes place according to predefined schedules.
When should partial deliveries be accepted?
Partial deliveries are useful when the delivered quantity is sufficient to avoid production stoppages and the replenishment delivery takes place promptly. The decision depends on the criticality of the items and available inventory levels.
How are additional costs for partial deliveries handled?
Additional transport costs caused by partial deliveries are generally borne by the supplier, provided this has been contractually agreed. In cases of force majeure or at the customer's request, the additional costs may also be borne by the buyer.
What legal aspects must be considered for partial deliveries?
Partial deliveries must be contractually regulated or accepted by the buyer. Without a corresponding agreement, the buyer may demand complete delivery or withdraw from the contract in the event of significant delays.
