Delivery time calculation

If you would like to use these functionalities, contact our Support team for more information and activation support.

The delivery time calculation determines, for each sourcing option, the estimated date on which the recipient (either the end customer or an ordering facility) will receive the requested goods.

The calculation takes the following factors into account:

• Earliest possible picking start: Considers stock availability, fulfillment times, and capacity constraints

• Average fulfillment buffer: Represents the average time required to pick an order in a specific facility

• Facility connection cutoff times: Indicates when goods are typically handed over to the carrier

• Facility connection transit time: Specifies how long a particular transfer usually takes

Example use cases

Example 1: Simple use case

In this simple example, the facility Store New York delivers directly to the consumer via DHL without any intermediate stops or internal supply steps.

The calculation of the estimatedDeliveryDate in this case would proceed as follows:

• Time point of request: Monday, 25/08/2025: 09:00

• earliestPickingStart: Monday, 25/08/2025: 10:00

  • fulfillmentTimes of Store New York: Monday-Friday: 10:00-18:00

  • No capacity limitations are set

• fulfillmentprocessbuffer of Store New York: 120 minutes

• CutoffTimes for facilityConnection Store New York to consumer: Monday-Friday: 16:00

• TransitTimes for facilityConnection Store New York to consumer:

  • no packagingUnitsbyContext defined

  • fallbackTransitTime: 1-2 days

  • transitTime calculationStrategy: earliest

• no nonDeliveryDay within transitTime

= estimatedDeliveryDate: Tuesday, 26/08/2025

Example 2: Complex use case

In this more complex use case, the consumer will receive two partial deliveries. Additionally, an external supplier ships the goods first to the Los Angeles store, where they are consolidated with items already in stock. After consolidation, the goods are forwarded to the consumer via DHL.

The calculation of the estimatedDeliveryDate in this case would proceed as follows:

• Time point of request: Monday, 25/08/2025: 09:00

Parcel 1: Store New York to consumer via DHL

• earliestPickingStart: Monday, 25/08/2025: 10:00

  • fulfillmentTimes of Store New York: Monday-Friday: 10:00-18:00

  • No capacity limitations are set

• fulfillmentprocessbuffer of Store New York: 120 minutes

• CutoffTimes for facilityConnection Store New York to consumer: Monday-Friday: 16:00

• Calculated targetTime is Monday, 25/08/2025: 16:00 (at this point in time DHL picks up the goods in New York)

• TransitTimes for facilityConnection Store New York to consumer:

  • No packagingUnitsbyContext defined

  • fallbackTransitTime: 1-2 days

  • transitTime calculationStrategy: earliest

• No nonDeliveryDay within transitTime

= estimated arrival date of requested item 1 at consumer: Tuesday, 26/08/2025

Parcel 2: Supplier 1 to Store Los Angeles via UPS

• As facilities of type "SUPPLIER" are externally operated, there is no information about fulfillment times, fulfillment process buffer, or capacities

• CutoffTimes for facilityConnection Supplier 1 to Store Los Angeles: Monday-Saturday: 14:00

• Calculated targetTime is Monday, 25/08/2025: 14:00 (at this point in time UPS picks up the goods at Supplier 1)

• TransitTimes for facilityConnection Supplier 1 to Store Los Angeles:

  • packagingUnitsbyContexts are defined and the ordered items 2 and 3 are fitting in packagingUnit M

  • transitTime for packagingUnit M: is 3 -3 days

  • transitTime calculationStrategy: earliest

• no nonDeliveryDay within transitTime

= estimated arrival date of requested item 2 and 3 at Store Los Angeles: Thursday, 28/08/2025

Parcel 3: Store Los Angeles to Consumer via DHL

• Store Los Angeles already has item 4 in stock

• Since items 2 and 3 are scheduled to arrive in Los Angeles on 28/08/2025 and the exact arrival time can't be predicted, it's assumed that processing of the goods will only begin one day later, which in this case means on 29/08/2025

• earliestPickingStart: Friday, 29/08/2025: 08:00

  • fulfillmentTimes of Store Los Angeles: Monday-Friday: 08:00- 17:00

  • No capacity limitations are set

• fulfillmentprocessbuffer of Store Los Angeles: 180 minutes

• CutoffTimes for facilityConnection Store Los Angeles --> Consumer: Monday-Friday: 17:00

• Calculated targetTime is Friday, 29/08/2025: 17:00 (at this point in time DHL picks up the goods in Los Angeles)

• TransitTimes for facilityConnection Store Los Angeles --> Consumer:

  • no packagingUnitsbyContext defined

  • fallbackTransitTime: 2-3 days

  • transitTime calculationStrategy: earliest

• Sunday is a nonDeliveryDay

= estimated arrival date of requested items 2, 3, and 4 to the consumer: Monday, 01/09/2025

Total

In total, the consumer will receive two partial deliveries with this sourcing option:

• Parcel 1 containing item 1 will arrive 26/08/2025

• Parcel 3 containing items 2, 3, and 4 will arrive 01/09/2025

For the delivery time rating, the date considered is always the point at which the customer has received all partial deliveries. In this case, 01/09/2025.
