Logistics AI build or buy: compare aligned costs, benefits and operating ownership

Compare logistics AI build and buy options on one defined workflow, such as scheduling, document preparation or lookup. Both face the same data, quality, interface, permission and operating requirements.

Do not compare a whole team's annual investment directly with a supplier's single-task quote. Establish horizon, volume, acceptance and internal coordination, then obtain each option's project-specific cost evidence.

Align responsibility and expense scope

Internal, external or mixed arrangements all require internal decisions and coordination. Existing capabilities and dependencies shape estimates; option labels do not establish lower cost, speed or complete ownership transfer.

The GAO cost guide supports scope, baseline, assumptions, alternatives, sensitivity and actual-cost records, not market salary or consultant rates.

Include preparation, use and operation

Assess source units, gaps, updates, access and available interfaces. Record preparation, integration, review, training, model/tool use, changes, support and exit. Separate initial and recurring costs; identify inclusions, owners and estimate sources.

Measure opportunities, eligible tasks and accepted completion separately. Evaluate errors, effort and service after source, model or operating changes before deciding on correction, retraining or other responses. Fixed-calendar retraining is not a required expense for every workflow.

Separate benefits by unit

Human work: compare lookup, preparation, review, changes and recovery together. Released hours times agreed work cost value capacity. Lower spending needs staffing, outsourcing, overtime or other expense records. The UK Government Efficiency Framework distinguishes cash effects from non-cash productivity as a method, not local accounting rules.

Distance-related cost: define baseline distance for aligned work. If r is the relative reduction in baseline annual empty distance D:

Annual distance saved = D × r

Value it using avoidable cost per kilometre in matching units, then check actual expenses. Trip counts are not distance. For a per-trip model, multiply kilometres saved per trip by comparable trips instead. Retain price, order-mix and concurrent changes.

Service losses: define stockout, delay and return events, denominators, comparisons and handling costs separately. Stockout rates are not forecast accuracy. Better service events do not automatically establish revenue or profit; finance confirms attributable valuation and overlaps.

Name ROI conventions and model payback separately

With positive same-horizon total cost C, period ROI can mean (compatible monetary benefits B − C) / C, multiplied by 100% for a percentage. Align periods and valuation basis, reporting cash and capacity separately.

An initial-investment denominator can instead define a named annual-net-benefit return on initial outlay. Explain annual expenses and one-time investment treatment. This differs from total-period-cost ROI; count each expense once and compare consistent conventions.

Payback requires period-by-period cash investment and benefits rather than inference from annual ROI. Update actual costs, accepted work and benefits, test influential assumptions and decide to continue, prepare further or stop without a universal payback-month rule.
