Use this logistics calculation for a transparent shipment, inventory, warehouse, customs, packaging, carrier, or service-level estimate when the governing units and business rules are explicit.

Delivered at

Doorstep delivery timestamp (ISO 8601).

Ordered at

Order placement timestamp (ISO 8601).

Target hours

Delivery promise in hours.

Measure elapsed hours between order placement and doorstep delivery and check the result against a delivery-promise target in hours. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Elapsed hours

Elapsed time from order to door in hours.

SLA met

True when delivery met the target.

• Carrier tariffs, customs rules, dangerous-goods requirements, hours-of-service rules, surcharges, port terms, dimensional divisors, and service definitions vary by jurisdiction, contract, date, mode, and commodity. A calculation is not a booking, classification, or compliance determination.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Verify current carrier and authority documents, retain shipment dimensions and timestamps, test boundary cases, and reconcile estimates against invoices and operational scans.

• Delivery Time Slot Promise Percentile

  Compute the p-th percentile (linear interpolation between closest ranks) of observed door-to-door delivery minutes to set a promised time slot that the fleet can keep.

• Concealed Damage Window Checker

  Check elapsed time against a configurable concealed-damage notice window. Confirm the applicable carrier contract, tariff, bill of lading, and law rather than treating the five-day planning default as a universal deadline.

• Detention Detach Hours Trigger Checker

  Check driver wait hours at a facility against the free time allowance to see whether detention billing triggers.
