I looked at our VoIP invoice one day and tried to figure out what we were actually buying.
We had seats for everyone on the team. But when I pulled the call logs, roughly a third of those seats hadn't generated meaningful call volume in the past month. They existed. They were billed. They made zero calls.
That's not a staffing problem — it's a pricing model problem. Seat-based VoIP bills you for access, not usage. The vendor wins when your team is quiet. You're essentially subsidizing their revenue floor.
The number that stuck with me: seat-based plans waste around 34% of budget on idle users on average. That's not edge-case, that's structural. It's how the model works.
Consumption-based pricing flips this. You buy a pool of credits. They get used when calls happen. Nothing gets charged when nobody's dialing. For companies with variable call volume — which is most small teams, most agencies, most founders — it consistently beats flat-seat pricing on actual spend.
There's one scenario where seats win: very high, very consistent volume per user. If everyone on your team is making 400+ minutes of international calls per month without fail, a flat plan can undercut pay-as-you-go rates. Outside that threshold, you're almost certainly overpaying.
The full breakdown of why this model is costing more than it looks — including how to calculate your actual per-minute cost once you fold in seat fees — is here: Why seat-based VoIP pricing costs your business more than you think
Worth reading alongside the shared balance vs per-seat comparison if you're doing the math on a switch.
We built GlobCall on consumption pricing because it was the only model that felt honest. No seats. No contracts. Pay for what you use.
