Digital Servitization: How African Engineering Companies Can Turn Products into Recurring Revenue

By Clifford Benjamin Oppong · Founder, 6Cubits · 11 min read

You sell a generator, a pump, a compressor, a prefab structure — once. That product then earns money for its owner every day for fifteen or twenty years. Digital servitization is how you stay in that story — and get paid for it.

What is servitization — in plain language?

The term was coined back in 1988 by researchers Sandra Vandermerwe and Juan Rada, and it describes something simple: manufacturers competing by selling outcomes and services around their products, not just the products themselves. The academic literature — including the systematic review by Lightfoot, Baines and Smart that guided this article — traces how "product-service systems" became a serious growth strategy: a way to differentiate, defend against cheaper competitors, and earn from the huge installed base of equipment already out in the field.

Think of it as a ladder with three rungs:

  • Base services — you sell the product plus spares and a warranty. Most Ghanaian equipment businesses live here.
  • Intermediate services — you sell scheduled maintenance contracts, repairs, overhauls, condition monitoring, operator training. Predictable revenue begins.
  • Advanced services — you sell the outcome: guaranteed uptime, pay-per-use, power-by-the-hour. The customer stops buying a machine and starts buying what the machine does.

The most famous proof is Rolls-Royce: airlines pay for engine flying hours under long-term care agreements rather than simply buying engines — and by 2023 roughly 70% of its civil aerospace revenue came from services. Kaeser sells compressed air by the cubic metre instead of compressors. Caterpillar wraps telematics and maintenance agreements around machines its dealers sell across African mine sites.

What makes it digital?

Servitization existed before the internet — but it was hard, manual and easy to lose money on. The digital layer is what makes it work at African scale:

  • Connectivity in the product — a SIM card or IoT sensor in the equipment reports usage, condition and location.
  • Mobile money — micro-payments and subscriptions collected without invoices chasing cheques.
  • Remote control — devices that can be enabled, throttled or locked over the air, which is what makes credit and pay-as-you-go viable.
  • Analytics — usage data that predicts failures before they happen and tells you exactly which customer needs which spare part, when.

That trio — embedded connectivity, mobile payments, remote lock/unlock — is precisely the combination that built Africa's pay-as-you-go solar industry. It is not a Silicon Valley fantasy; it is already running in Accra, Kumasi and Tamale.

Proof from Ghana and Africa

Zipline: selling deliveries, not drones

Zipline could have tried to sell drones to the Ministry of Health. Instead, Ghana pays a fixed service fee for guaranteed medical deliveries — a contract worth about $12.5 million over four years, serving some 2,000 health facilities from distribution centres running 24/7. Government buys the outcome (medicine delivered in minutes); Zipline owns, operates, monitors and maintains the fleet. That is advanced servitization, operating from Omenako, not Ohio.

PEG Africa / Bboxx and M-KOPA: the PAYG blueprint

PEG Africa (now part of Bboxx) built a Ghanaian business putting SIM-enabled solar home systems into homes on credit — customers pay in small mobile-money instalments, and the embedded meter can be remotely disabled if payments stop. M-KOPA runs the same playbook across Africa with solar and smartphones: the GSM chip inside the device handles payments, credit and control. The hardware is the entry ticket; the recurring payment stream and the data are the business.

Kofa: energy as a subscription

Accra-based Kofa doesn't sell batteries to motorcycle riders — riders subscribe to its "Swap & Go" network and exchange depleted batteries for charged ones in seconds at stations across Accra and Kumasi (33 stations and growing, backed by a £6.15m programme with PASH Global and Shell Foundation). Kofa's IoT platform authenticates each battery to its user automatically, even offline. A hardware company earning like a telco.

Mining and heavy equipment

Walk any large Ghanaian mine site and the servitization is already visible: OEM dealers selling maintenance-and-repair contracts, telematics subscriptions and condition monitoring alongside machines — because an hour of unplanned downtime on a critical asset can cost hundreds of thousands of dollars. The question is no longer whether this model works in Ghana. It's why your firm isn't earning from it yet.

Why this matters to your engineering business

  • Reduce cost. Remote monitoring cuts "truck rolls" — technicians travel when data says so, not on a guess. Predictive maintenance turns emergency callouts (overtime, air-freighted spares, angry customers) into planned work.
  • Reduce rework. Field data flows back into design and production. When you can see how products actually fail in Ghanaian heat, dust and voltage conditions, the next batch fails less — and warranty claims drop.
  • Master after-sales. An installed-base register — which unit, which customer, which condition, which contract — is the difference between an aftermarket business and answering the phone when something breaks. Spares stop leaking to grey-market suppliers.
  • Earn recurring revenue. Maintenance contracts, monitoring subscriptions, uptime guarantees, pay-per-use pricing and data services smooth the feast-and-famine cash flow of project work — and services typically carry better margins than hardware in a weak-cedi environment where imported product margins get squeezed.

The 6-step playbook to start (without betting the company)

  • 1 · Pick one product line with an installed base. Not everything — one line of generators, pumps, kilns, towers or panels where you already have 50+ units in the field and customers who feel the pain of downtime.
  • 2 · Build the installed-base register. Before any sensor: which units, where, whose, what condition, what history. Most firms discover they can't answer this — that discovery alone is worth the exercise.
  • 3 · Instrument affordably. Retrofit telematics or sensors on a pilot batch — GSM-based, offline-tolerant, solar-buffered where power is unstable. You need hours-run, temperature, vibration or usage counts — not a NASA dashboard.
  • 4 · Design the offer ladder and price it. Bronze: inspection + priority spares. Silver: full maintenance contract with monitoring. Gold: uptime guarantee or pay-per-use, billed by mobile money or monthly invoice. Price against the customer's cost of downtime, not your cost of labour.
  • 5 · Sell it to five existing customers. Your best pilot customers already own your product and already call you when it breaks. Convert those relationships into contracts with a service-level promise and a dashboard they can see.
  • 6 · Stand up the service P&L and the people. Give services its own targets, its own margin line and a named owner. Train technicians to sell and deliver contracts. This is where transformations succeed or quietly stall.

The honest risks

Research warned about this early: Gebauer and colleagues named the "service paradox" — companies that invest in services yet never see the revenue, usually because the organisation, pricing and mindset never actually changed. Outcome contracts also transfer risk to you: guarantee uptime you can't deliver and the penalty clauses will find you. And subscription models trade big invoices today for steady cash tomorrow — finance must model that bridge deliberately. This is why servitization is a transformation programme — technology, processes and people together — not a gadget purchase.

Where to start this quarter

Two moves. First, take the free Digital Maturity Scan — servitization sits on top of the same six dimensions we measure, and it will show whether your data, processes and people are ready. Second, look at our new Servitization Launchpad — a 90-day programme in which 6Cubits acts as your solutions architect and product manager: we build your installed-base register, connect a pilot batch of products, design the offer ladder and pricing, and get your first paying service contracts live.

Your products are already out there, working every day. It's time they worked for you twice.
