Product-as-a-Service gives a customer the use of a physical asset, or an agreed output from it, while the provider retains ownership and specified service responsibilities. The useful question is what the contract transfers: acquisition cost, maintenance work, failure risk, residual value, or measurable performance. A monthly invoice establishes none of those on its own.

Section 1

Identify what you are buying

A subscription describes recurring access or payment. Rental provides temporary asset use and can include services. Product-as-a-Service overlaps with rental when the provider also manages the asset across its life; an outcome contract goes further by defining what usable performance must be delivered. These are practical distinctions, not mutually exclusive legal categories.

Performance-based maintenance is another arrangement: a supplier can accept repair-cost risk while the customer or a third-party lessor owns the equipment. Do not infer ownership from a service name. Read title, coverage, payment and exit provisions separately.

For a buyer, compare the cost of an equivalent usable result. For a provider, test whether the promised payment covers funding the asset, servicing it and recovering it at the end. A provider that controls repairs but cannot influence misuse or demand may need exclusions, minimum payments or a different price.

Section 2

Three examples with different evidence

These are public disclosures checked September 7, 2026. The Hilti document is an unsigned framework; the other sources are provider descriptions. None supplies an individual customer's complete signed terms. Missing detail below means the reviewed source does not establish it.

Ownership, payment and service risk

Example and scope	What is disclosed	What needs checking
Hilti Fleet Management Great Britain; GB VPL2024.10 framework.	Hilti retains tool ownership, without a purchase option (§11, p2). Individual Tool Contracts set monthly fees and periods (§2, p1). Repairs have exclusions (§4.1, p1); loans depend on availability and may differ from the original (§5.2, p2).	Customer early Tool Contract termination is unavailable (§2); framework termination has separate grounds (§13, p3). Non-return extends monthly billing (§8.3, p2). Check individual terms, exclusion lists and price-adjustment conditions (§14, p3). Read the framework.
Philips/Cofely at Schiphol Netherlands; April 16, 2015 announcement.	Schiphol pays for light; Philips retains fixtures and installations. Philips/Cofely take performance, durability and end-of-life responsibilities. Lighting intensity and reliability use a KPI model.	Tariffs, numerical targets, remedies and early-exit terms are undisclosed. The announced 50% electricity reduction was prospective, not a verified outcome. Read the dated announcement.
Rolls-Royce TotalCare Undated service page; individual contract jurisdiction unspecified.	A related maintenance-risk example: payment per engine flying hour; time-on-wing and planned/unplanned shop-visit cost risks transfer to Rolls-Royce.	Engine ownership, individual rates, exit terms and a quantified uptime guarantee are not established. This is not evidence that Rolls-Royce owns every covered engine. Read the service description.

Section 3

Make the obligations explicit

Funding and residual value. Who pays before the first useful hour? Record the deposit, installation cost and financing terms. Identify who receives resale proceeds and who pays for damage, removal or an asset with little remaining value. Retaining title does not mean accepting every loss.

Maintenance and utilization. Who schedules service, pays for parts and supplies replacements? Separate routine wear from misuse and excluded consumables. Then ask who controls demand. An idle asset still needs financing; a minimum fee can transfer part of that utilization risk back to the customer.

Usable output. Specify a unit that matters to the buyer, its quality threshold and measurement method. Billed operating hours are not automatically productive hours. Define planned downtime, disputed readings and the evidence both parties can inspect. A performance claim without a measurable threshold and remedy is hard to compare.

Remedies and exit. Record service credits, repair deadlines, substitutes and liability limits. Check minimum payments, escalation, cancellation, return conditions and settlement costs. A low headline fee is incomplete if the buyer must pay through a period when the asset is no longer needed.

Section 4

A fictional 36-month buyer comparison

This exercise uses invented terms, unrelated to the companies above. Assume both options deliver the same usable output at each usage level. Ownership costs $12,000 today, plus $140 each month for maintenance and insurance, with $3,000 resale proceeds at month 36. Service costs $220 per month plus $4 per used hour, including the same assumed maintenance and insurance coverage. All recurring payments occur at month-end; service has no deposit, exit charge or residual receipt.

Both options exclude equal energy, consumables and tax. Downtime costs are also excluded because none have been supplied; equal usable output is an assumption, not a demonstrated service guarantee. All amounts in this fictional example are US dollars (USD). Use one currency throughout when replacing the inputs. The 8% effective annual discount rate is an illustrative opportunity cost, not a market borrowing quote.

Use the buyer comparison workbook to replace the fictional inputs with your own assumptions.

Discount monthly cash flows

r = (1.08)^(1/12) − 1 ≈ 0.6434% per month
A = [1 − (1 + r)^(−36)] / r ≈ 32.0433
Ownership present cost = 12,000 + 140 × A − 3,000 / (1 + r)^36
Service present cost = (220 + 4 × monthly hours) × A

The ownership net present cost is $14,104.57. Dividing by A gives an equivalent month-end cost of $440.17. That is a comparison measure, not the buyer's actual monthly bill: the $12,000 still leaves immediately.

Constant monthly usage: fictional results

Positive differences mean service costs more than ownership in present-value terms.

Hours/month	Service/month	Service present cost	Difference
30	$340	$10,894.73	−$3,209.84
60	$460	$14,739.93	+$635.36
90	$580	$18,585.13	+$4,480.56

The cost crossover is (440.1718 − 220) / 4 = 55.04 hours per month, using unrounded values. Below it, service has the lower modeled present cost; above it, ownership does. This assumes constant use and unchanged operating costs. With seasonal use, discount each month's actual expected payment rather than inserting an unweighted average.

Section 5

Change the assumptions before deciding

Test repair costs, residual proceeds and financing independently. An extra $50 monthly ownership cost raises its equivalent monthly cost by $50 and shifts the crossover upward by 12.5 hours. Losing $1,000 of month-36 resale proceeds adds about $24.77 to equivalent monthly ownership cost. Neither change estimates any named company's economics.

If financing the purchase, model the deposit, borrowing and repayments consistently; do not add loan payments on top of the full cash purchase without accounting for the loan proceeds. A higher discount rate changes how upfront and deferred cash flows compare. Different repair exposure, output quality or downtime can outweigh a small modeled price difference.

FTN decision analysis

Choose the arrangement whose economics and obligations fit your expected use. Before deciding, replace the fictional inputs with dated quotes, a realistic usage range and the clauses that allocate failure and exit costs. If a missing term could reverse the result, keep the decision open until that term is known.
