Bolna Rule: Price Per Minute Before You Promise a Retainer

Can our agency quote a fixed monthly retainer on Bolna without losing margin when client call volumes run past the pilot? Model every Bolna engagement at $0.06 per minute of agent runtime and set a call-volume ceiling in the client contract before you quote a flat retainer.

“Can our agency quote a fixed monthly retainer on Bolna without losing margin when client call volumes run past the pilot?”

Model every Bolna engagement at $0.06 per minute of agent runtime and set a call-volume ceiling in the client contract before you quote a flat retainer.

Common Mistake

Agencies quote a fixed monthly retainer off a single pilot week of call data, then absorb the overage themselves when a client's inbound volume doubles, because the $0.06 per minute line was never converted into a contractual minute ceiling or an overage clause.

Why This Works

Bolna bills pay-as-you-go at $0.06 per minute with flexible credits and top-up when balance runs low, so cost scales with talk time rather than with seats or accounts. The verdict flags exactly this: per-minute runtime creates variable cost exposure when clients exceed expected call volumes, and the Pilots Plan and committed-volume Plan are quote-based rather than published. Sub-accounts make multi-client delivery workable at 5+ deployments, but they do not cap the minutes each client burns.

Apply When
  • •The client's use case is inbound support, cart recovery, recruitment screening, or COD confirmation in Hindi, Hinglish, Tamil, Telugu or another of Bolna's 10+ Indian languages
  • •You are scoping a retainer for a client whose monthly call minutes are not yet measured, or are estimated from a sample week
  • •The agency plans to run 5 or more concurrent client deployments and needs Bolna sub-accounts to keep them separated
  • •Telephony already runs through Twilio or Plivo, so Bolna's native integrations shorten build time rather than adding a migration
  • •The client wants a pilot before commitment and 12,000 included minutes would cover the trial period
