The Real Cost of Running Three Vendors for One Phone System

Most New Zealand businesses didn’t choose to run three separate communications vendors. It happened one decision at a time: broadband from one provider because it had fibre first, mobile from another because someone got a good deal, and a phone system from whoever installed it when the office moved. Nobody sat down and designed it this way. But that’s exactly how most SME communications setups end up — assembled, not built.

The direct cost of this is usually visible: three invoices, three contract renewal dates, three account managers who don’t know the others exist. What’s less visible, and usually more expensive, is what happens when something breaks.

Take a common scenario: the office internet drops mid-morning. Is it the broadband connection, the router, the phone system, or the mobile failover? Nobody in the building can say for certain, so someone has to ring the broadband provider first, get told it’s not their end, then ring the phone system vendor, get told it’s not their end either, and eventually land on the actual cause an hour or two later. Every one of those calls is time an office manager isn’t spending on their actual job, and every hour of downtime is lost calls, missed enquiries, and a team standing around waiting.

This is the hidden cost of vendor fragmentation: not the invoices, but the coordination tax. Somebody in the business — usually whoever’s least equipped to diagnose a telecommunications fault — becomes the unpaid integrator between three companies who each have an interest in the fault being someone else’s problem.

There’s a second cost that’s harder to quantify but just as real: inconsistent service levels. A broadband provider’s idea of “priority support” and a PBX vendor’s idea of the same phrase can be wildly different, and when an SME is a small account for each of them individually, none of the three has much incentive to move quickly. Scale matters in vendor relationships, and splitting spend three ways means being a small fish in three ponds instead of a meaningful account in one.

The alternative isn’t complicated, even if the switching process can feel daunting: one provider responsible for connectivity, calling, and mobile, with a single support number and a single point of accountability. When something breaks, there’s no ambiguity about who picks up the phone, and no incentive for anyone to point elsewhere. The provider who sold the connection is the same provider who built the phone system on top of it, so they have every reason to make sure the whole stack works together — because when it doesn’t, there’s nowhere for them to hide.

This is the model Digital Island has built its business around. As an NZ-owned business communications and connectivity specialist — not a generic telco reselling someone else’s platform — Digital Island brings broadband, mobile, and business calling under one roof, backed by support that’s NZ-based and available around the clock. The point isn’t that a single vendor is always cheaper line item for line item; sometimes it isn’t. The point is that a single vendor removes the coordination tax altogether: no more triangulating between three support desks to find out whose fault an outage is, and no more discovering mid-crisis that “priority support” means something different to everyone involved.

There’s a version of this that shows up every March or June, too, when end-of-year reconciliation means someone has to match spend against budget across three completely separate billing systems, three different invoice formats, and three different customer portals with three different logins. None of that work adds value to the business — it’s pure overhead created by the vendor structure itself, not by anything the business actually needs. A single consolidated invoice from a single provider doesn’t just save an afternoon of admin twice a year; it means whoever holds the budget can actually see, at a glance, what the whole communications spend is costing the business, rather than reconstructing it from three statements that were never designed to sit next to each other.

For a growing SME, the practical test is simple: next time something goes wrong with your business communications, count how many phone calls it takes before someone actually starts fixing the problem, rather than ruling themselves out of it. If the answer is more than one, that’s not a technology problem, it’s a vendor structure problem — and one that gets more expensive, not less, as the business grows and the stakes of downtime rise.
