1
Calculate the complete 3-year cost
|
Acquisition cost, logistics, installation, service, and training
|
Illustrative planning case: equipment price US$42,000;
freight, insurance, and import charges US$6,000;
installation and training US$4,000;
preventive service US$3,600 per year.
|
3-year TCO = US$42,000 + US$6,000 + US$4,000 +
(US$3,600 × 3) = US$62,800.
Exclude coffee, milk, cups, payment fees, rent, and taxes unless they are being compared separately.
|
Request a written quotation that separates machine price, shipping terms,
customs responsibility, commissioning, software fees, warranty coverage, and recurring service charges.
|
Compare at least three quotations using the same delivery term and the same operating period.
A low purchase price may produce a higher TCO if service, software, or spare parts are expensive.
|
|
2
Measure ROI using contribution profit
|
Daily volume, selling price, ingredient cost, labor saving, and annual operating cost
|
Illustrative operating case: 80 cups per day,
average selling price US$4.50,
contribution margin after ingredients and payment fees 55%,
labor saving US$32,000 per year.
|
Annual sales = 80 × 365 × US$4.50 = US$131,400.
Contribution profit = US$131,400 × 55% = US$72,270.
If annual service and utilities total US$8,000, estimated annual benefit =
US$72,270 + US$32,000 − US$8,000 = US$96,270.
|
Validate the expected cup volume with location traffic, opening hours, average queue time,
menu mix, and seasonal demand. Do not use revenue alone as ROI.
|
Use conservative, base, and optimistic scenarios. Test the model at 50, 80, and 110 cups per day
before approving the investment.
|
|
3
Check payback and cash-flow risk
|
Initial investment, monthly benefit, financing cost, and break-even volume
|
Using the illustrative US$62,800 three-year cost and US$96,270 annual benefit,
simple payback is approximately 7.8 months before taxes and financing.
Actual payback will be longer if utilization is lower.
|
Simple payback period = initial cash investment ÷ monthly net benefit.
Break-even cups per day = monthly fixed cost ÷ contribution per cup ÷ operating days.
|
Include deposit timing, currency exchange, financing interest, local taxes,
downtime, product waste, and the cost of replacing the unit earlier than planned.
|
Set an internal payback limit, such as 18–24 months, and approve the purchase only
if the base-case scenario remains below that limit.
|
|
4
Verify capacity and drink consistency
|
Peak-hour output, preparation time, drink accuracy, and menu flexibility
|
A suitable specification should state tested throughput rather than only maximum theoretical capacity.
For many self-service locations, a planning target of 20–40 drinks per hour
may be more useful than a headline daily figure.
|
Required hourly capacity = peak-hour orders × safety factor.
Example: 25 peak-hour orders × 1.25 = 31.25 drinks per hour minimum target.
|
Ask for a live or recorded acceptance test covering temperature, extraction time,
portion accuracy, milk performance, cleaning interruptions, and simultaneous orders.
|
Test the robot with the intended cup sizes, recipes, payment flow, water quality,
local voltage, and actual peak-hour demand before final acceptance.
|
|
5
Evaluate maintenance and consumable logistics
|
Cleaning time, spare parts availability, water requirements, and service intervals
|
A practical service plan should identify daily cleaning tasks, weekly checks,
scheduled preventive maintenance, and common replacement parts.
Target spare-part dispatch time: 7–14 calendar days
for standard components.
|
Annual maintenance burden = scheduled service cost +
consumable replacement cost + internal staff hours + expected downtime cost.
|
Confirm whether filters, seals, pumps, grinders, milk lines, touchscreens,
and payment modules are locally stocked or shipped internationally.
|
Purchase a starter spare-parts kit and document cleaning responsibilities,
escalation contacts, preventive-maintenance intervals, and safe shutdown procedures.
|
|
6
Assess supplier reliability objectively
|
Warranty, uptime, response time, references, cybersecurity, and financial continuity
|
Useful contract targets include 98% monthly operational availability,
remote response within 4 business hours, and a documented
corrective-action plan for repeated failures.
|
Availability = (scheduled operating hours − downtime) ÷ scheduled operating hours × 100.
Example: 300 scheduled hours and 6 hours of downtime = 98% availability.
|
Request two or more customer references in comparable climates and operating environments.
Review warranty exclusions, software support duration, data ownership, cybersecurity updates,
and the supplier's ability to provide parts after the warranty period.
|
Link service payments or renewal terms to measurable service levels.
Include repair-time limits, spare-part obligations, escalation procedures, and termination rights.
|
|
7
Confirm compliance, localization, and scalability
|
Electrical certification, food safety, accessibility, language, payment integration, and expansion
|
Confirm compatibility with the destination market's voltage and frequency,
local food-contact requirements, electrical safety rules, payment regulations,
accessibility expectations, and data-protection obligations.
|
Deployment readiness score = completed compliance items ÷ total required items × 100.
A buyer should target 100% completion before commercial launch.
|
Check certification documents, import classification, labeling, allergen information,
cleaning chemicals, user-interface languages, payment integration, remote monitoring,
and the process for software updates.
|
Run a site pilot before a multi-location rollout. Use pilot results to standardize recipes,
training, maintenance, reporting, and spare-parts inventory for future locations.
