Network as a Service or CapEx: Choosing the Right Model for a South African Estate

Every network refresh eventually lands on the same board question: do we buy the equipment, or do we consume the network as a service? In South Africa, where import pricing swings with the rand and hardware lead times stretch for months, that question has real weight.
Neither answer is universally correct. What follows is the honest comparison, including the cases where owning your hardware is still the right call.
The real cost of buying outright
The purchase order is only the visible part. A CapEx refresh carries costs that rarely appear in the original business case.
- Currency exposure: Network hardware is priced in dollars. A weak rand at the wrong moment can add double digit percentages to a budget approved months earlier.
- Spares you hope never to use: Meaningful redundancy means buying cold spares that sit in a cupboard depreciating alongside the live kit.
- Skills to run it: Owning equipment means owning the monitoring, patching, firmware discipline and after-hours response that keeps it healthy.
- The end-of-life cliff: Five years on, vendor support lapses and the whole estate needs replacing at once, usually in a year the budget was earmarked for something else.
What NaaS actually shifts
Network as a Service converts that lumpy capital cycle into an operating subscription that bundles hardware, licensing, monitoring and support.
- Predictable monthly cost: One line item per site, which makes multi-year budgeting and internal cost allocation far easier to defend.
- Refresh becomes someone else's problem: Hardware lifecycle, firmware currency and replacement of failed units sit with the provider, not your team.
- Scale that follows the business: Opening a branch adds a subscription. Closing one removes it, instead of leaving you with stranded assets.
- Support included, not negotiated: Monitoring, incident response and on-site attendance are part of the service rather than a separate contract each year.
When CapEx still wins
Be sceptical of anyone who says subscription always beats ownership. Buying outright remains sensible when:
- Your estate is static: A single stable site with no growth plans and strong in-house skills may simply not need the flexibility premium.
- Capital is cheap for you: Organisations with available capital and favourable tax treatment on assets sometimes come out ahead over a full seven year hold.
- Compliance demands full ownership: Certain regulated or sovereign workloads require assets and control paths that a shared service model complicates.
How to decide in one afternoon
- 1
Build a five year total cost view
Include hardware, licences, spares, support contracts, staff time and the cost of the refresh at the end. Compare that against the equivalent subscription total.
- 2
Price the risk, not just the kit
Put a number on downtime per site per hour. A model that shortens response time has measurable value even when it looks more expensive on paper.
- 3
Match the model to the site type
Most South African estates end up hybrid: owned core at head office, subscription network at branches where local skills are thin.
How 2bo approaches it
We model both options against your actual site list and growth plan, then build the mix that fits. Owned where ownership makes sense, managed subscription where it removes risk you should not be carrying.
