Billing, plans and tax

What plans control

Plans decide which paid features your business can use. SIMCOAI blocks spend-heavy features when a subscription is inactive, unpaid, cancelled, incomplete or outside plan limits.

Use Stripe for payment changes

For security, the Customer Portal is the self-service place for cards, invoices, tax IDs, subscription updates and cancellations. SIMCOAI reads Stripe status and enforces entitlements from the backend.

• Add or update payment methods
• Download hosted invoices
• Add business tax IDs where required
• Change or cancel subscriptions
• Recover billing after failed payments

Allowances and how usage resets

Each plan includes monthly allowances (conversations, AI call minutes, API requests, AI tokens and more) plus live caps (active phone numbers, API keys, team seats). Open Plan & Usage to see exactly what you have, what has been used and when period allowances reset — usage‑based allowances reset when your Stripe subscription renews; live caps do not reset.

• Watch usage before a launch or a busy period so you do not hit a cap mid‑flow.
• Limits are enforced server‑side, so the number you see is the number that applies.

Optional, capped overage billing

Pay‑as‑you‑go lets usage continue past your included allowances instead of stopping — but it is optional and always capped, never unlimited. In Billing you set two limits and accept the terms:

• Monthly cap — the soft limit for overage in a billing period.
• Hard stop — SIMCOAI never bills beyond this; usage pauses when it is reached.

The page shows your projected overage this period and the per‑unit rates before anything is charged. Leave it off and usage simply stops at your included allowance. Overage still depends on successful Stripe payment, provider availability and compliance controls.

Add-ons and free trials

• Add‑ons unlock extra capability on top of your plan (for example SIMCOAI Voice for premium voices and larger voice usage, premium AI models, extra numbers). Open any add‑on’s Details to see what it includes before adding it; it is billed through Stripe alongside your plan.
• Free trial: new accounts can start a 7‑day Stripe trial; promotion codes are supported at checkout where available.
• Change or cancel any time from the Stripe portal; changes take effect at the next billing cycle unless stated otherwise.

Prices and tax handling

Prices are shown in GBP and may exclude VAT or other taxes unless Stripe shows otherwise during checkout or on invoices. Do not add a VAT number to public pages unless SIMCOAI has a valid one.
