Do add-on calls roll over?

Yes, indefinitely. Plan quota resets monthly, but add-on balance is consumed only after the monthly quota is exhausted, and unused add-on calls stay in your balance forever.

Can I buy multiple add-on packs?

Yes. Each purchase adds 100 calls to your add-on balance. Buy three at once or three over the month — the result is the same.

Are add-ons charged immediately?

Yes. Add-on packs are one-time purchases through Stripe Checkout. The 100 calls land in your add-on balance the moment the charge completes.

Why is the same add-on listed in my Stripe history twice?

It's not, even if the checkout flow stuttered. Add-on purchases are idempotent on the Stripe checkout session ID — a duplicate redirect to the same session does not double-charge or double-credit.

How do call add-on packs work?

Billing·May 31, 2026·1 min·By Callmine Team

Buy a 100-call add-on for $10 from Settings → Billing. One-time purchase, rolls over forever, consumed only after monthly quota is exhausted.

TL;DR

When you need more calls than your monthly plan allows, buy a 100- call add-on for $10. One-time purchase. Add-on balance rolls over forever and is consumed only after your monthly quota is exhausted.

Steps

01Open /settings and switch to the Billing tab. Find the Add-on packs section.
02Click Buy 100 calls. Callmine redirects you to Stripe Checkout for a one-time payment.
03Complete the payment. Stripe redirects back to Callmine and the 100 calls land in your add-on balance immediately.
04Continue running analyses normally. Quota is consumed in order: monthly plan first, add-on balance second.

How consumption order works

Every analyzed call deducts from one of two buckets, in this strict order:

01Current month's plan quota. Resets at your billing anchor date. Unused plan calls do not roll over.
02Add-on balance. Persists indefinitely. Only consumed when plan quota for the current month hits zero.

This means add-on purchases are insurance against spike weeks. Buy a pack today, use it three months from now — the calls don't expire.

When to buy add-ons vs upgrade

·Buy add-ons when you have a one-off heavier month (board prep, QBR analysis, post-event win-loss). Adding a $10 pack is cheaper than upgrading to the next tier for one month.
·Upgrade when your typical month consistently exceeds your current plan. Two add-on packs every month means you should be on the next tier.

Idempotency and duplicate charges

Add-on purchases are idempotent on the Stripe checkout session ID. If the redirect path stutters or you accidentally re-submit, only one charge runs and only one 100-call credit applies. If you ever see what looks like a duplicate in Stripe, email hello@callmine.ai with the session IDs and we'll confirm.
