Is a monthly subscription or pay-per-minute better for AI calling?
Pay-per-minute is better when volume is uneven or still unknown; a subscription can be cheaper when you reliably use most of a fixed bundle every month. Outpero is pay-as-you-go only, at ₹5 to ₹6.8 per connected minute from prepaid credits that never expire, with no monthly base fee, so quiet months cost little and busy months scale up. Prices exclude 18% GST.
How the two models differ
| Pay-per-minute | Monthly subscription | |
|---|---|---|
| Fixed monthly cost | None, apart from any number rent | Plan fee, whether used or not |
| Unused minutes | Nothing is lost | Often lost at month end |
| Busy months | Cost rises with usage | Overage rate above the bundle |
| Budgeting | Varies with volume | Predictable |
| Best for | Seasonal, new or uneven calling | Steady, high, predictable volume |
The number that decides it
A subscription's real price is the plan fee divided by the minutes you actually use, not the minutes it includes. Take a hypothetical plan of ₹10,000 a month for 2,500 minutes. Used fully, that is ₹4 a minute. Used for 1,200 minutes, it is about ₹8.33 a minute.
On Outpero's Standard voice, 1,200 minutes cost ₹6,000, plus ₹649 for a dedicated number. In a month with 2,500 minutes, the cost is ₹12,500 plus ₹649. Which is cheaper depends entirely on your real usage, month by month.
When a subscription makes sense
If you run a call centre-scale operation with the same volume every month, a well-priced bundle can beat pay-as-you-go. It also suits finance teams that want one fixed invoice. Check the overage rate and whether minutes roll over before signing.
When pay-per-minute makes sense
- —You are starting out and do not know your volume yet.
- —Volume moves with seasons: admissions, festivals, launches, harvests, wedding months.
- —You want to stop or pause without paying for an idle plan.
- —You want to switch voice tiers by campaign without changing anything on your account.
Because Outpero's credits never expire, the usual drawback of prepaid wallets, losing an unused balance, does not apply.
A practical test: look at the last six months of call or lead volume. If the busiest month is more than double the quietest, a fixed bundle will either be too small in peak months or wasted in quiet ones, and pay-per-minute will usually come out ahead. If volume stays within a narrow band, get a subscription quote and compare it honestly.
