On-Demand is currently in beta. The behavior described below may change as we refine pricing and limits.
On-Demand is an opt-in overage layer for paid subscriptions. Your plan’s included usage is consumed first, followed by any usage credit in your wallet. Once both are exhausted, On-Demand lets Notis keep running and bills the extra usage separately. Think of it like a safety valve: instead of stopping mid-conversation when your included credits run out, Notis can continue as long as On-Demand is enabled, your payment method is valid, and you have not reached the On-Demand limit you set.

​
Who can use it?

On-Demand is available on every paid plan — Pro, Pro+, and Ultra — for any subscriber with a payment method on file. Accounts on the Free tier, and trials that have not been activated into a paid subscription, cannot enable it. If you’re on a team plan, only the team owner can change On-Demand settings. Team members inherit the owner’s configuration as read-only. Everyone on the team uses the same included usage pool and the same On-Demand limit.

​
How does it work?

  1. Notis consumes your included monthly usage and any wallet credit first — On-Demand stays idle.
  2. When both are exhausted, On-Demand kicks in and Notis keeps responding.
  3. Overage is tracked against your monthly On-Demand limit. On teams, this limit applies to the whole team, not each teammate.
  4. Notis periodically invoices the accumulated overage balance once it reaches your settlement threshold. Automatic payments are grouped so there is at most one successful On-Demand charge every 24 hours for you or your team.
  5. At the end of the billing cycle, Notis charges any remaining overage balance if it is large enough for Stripe to process. Tiny balances carry forward and are included in the next settlement.
You can monitor your overage usage and unbilled balance from the On-Demand section on the subscribe page.

​
The three modes

When you open the On-Demand card, you choose one of three modes:
  • Fixed — Set a hard monthly USD ceiling (for example, $20). The task that reaches the remaining limit can finish, but you are never billed above the limit. Later tasks pause until you raise the limit or a new billing cycle begins.
  • Unlimited — No monthly overage ceiling. Notis keeps working as long as your payment method stays valid. Use this if you’d rather not be interrupted and trust your team to self-regulate.
  • Disabled — Default. Once your included usage is exhausted, Notis pauses until your billing cycle resets or you upgrade.
Start with a Fixed limit that matches roughly one extra month of plan usage. You can switch to Unlimited later once you have a feel for your overage pattern.

​
How am I billed?

On-Demand is billed in arrears — you only pay for the extra model usage you actually use.
  • Each overage request adds to your unbilled balance using the same Notis model rates listed in Usage & model rates.
  • When your unbilled balance reaches your settlement threshold, Notis automatically charges the exact outstanding overage amount.
  • To reduce small card charges, successful automatic settlements are grouped to no more than one every 24 hours. Your exact new usage keeps accumulating for the next invoice during that window.
  • At the end of each billing cycle, Notis tries to settle any remaining overage balance before your usage counter resets.
  • If the remaining balance is too small for Stripe to charge, it carries into the next cycle and is included in your next settlement.
  • Carried overage does not reduce your next month’s included plan credits.
Your first settlement threshold is $1.00. As you build a good payment history, Notis can wait longer before charging so you see fewer small card charges: If an On-Demand payment fails, the threshold resets to $1.00 until the payment issue is fixed. If you use a Fixed monthly limit, that limit controls whether new overage can continue; it does not change the settlement threshold. For example, if your threshold is $5 and your overage balance is $3.20, Notis keeps tracking the balance but does not charge yet. If your next task brings the balance to $5.40, Notis charges $5.40. If your billing cycle ends with only $0.30 outstanding, that $0.30 carries forward and your included plan credits still reset in full. On-Demand charges are processed securely through Stripe as invoices. Each invoice shows the exact accumulated amount being settled and includes a hosted invoice page and downloadable PDF. You can find On-Demand and subscription invoices from the Notis portal → Manage Subscription → Invoice history.

​
What happens if a payment fails?

If Stripe can’t charge your card for an On-Demand settlement, your On-Demand status switches to suspended:
  • Further overage usage is blocked.
  • Your plan’s included usage still works normally until it’s exhausted.
  • A red banner appears on the On-Demand card.
If you’re the subscription owner, the banner can show:
  • Retry payment when there is an overage balance ready to charge.
  • Resume on-demand when the remaining balance is too small to charge right now.
  • Update payment when you need to change the card in Stripe.
After you update your payment method and return to Notis, Notis automatically retries the same open invoice for you. You can also click Retry payment from the On-Demand card. A failed retry does not create another invoice for the same balance. If the balance is too small for Stripe to charge, Notis can resume On-Demand and carry that small balance forward. It will be included the next time your overage balance reaches the settlement amount. If you’re a team member, ask your team owner to update payment or retry recovery. Team members can view the team’s On-Demand settings, but only the owner can change or recover them.

​
Enabling On-Demand

  1. Open the subscribe page in your portal.
  2. Scroll to the On-Demand section below the pricing grid.
  3. Pick Fixed (and set a monthly limit) or Unlimited.
  4. Click Save.
To turn it off, switch the mode back to Disabled and save. You’ll keep access to any unbilled balance through the end of the current cycle, and no new overage will be charged after the change takes effect.

FAQ

Does On-Demand reset every month? Yes. Your On-Demand usage counter resets at the same time as your plan’s billing cycle. Does carried debt reduce next month’s plan credits? No. If a sub-minimum balance carries forward, it’s added to your next settlement — your included plan credits reset in full. Can I cap a teammate’s On-Demand spend? On-Demand limits apply to the whole team subscription, not per-member. Use a Fixed limit to bound total team overage. Do team credits pool together? Yes. A team’s included usage is shared. If your team has 10 paid seats on Ultra, at $149 of monthly usage per seat, the team gets one $1,490 monthly pool. Does the 7-day trial include On-Demand? No. On-Demand is only available after you activate a paid subscription, on any paid plan.
