How to choose a plan, pay and manage your usage balance

A plan is needed to use the Trade Engine in production (live API keys). It isn't needed to host TBBN Spaces or to build against the free sandbox. Billing is per Business: one plan covers every Merchant account your Business runs.

Plan prices, allowances and per-call rates are in the pricing reference.

Open Billing

Go to business.tbbnetwork.com, open your Business and select Billing →. Owners and Admins can manage billing.

Choose a plan

Under Choose a plan to start production trading:

Pay-As-You-Go — billed weekly (Mondays) for what you actually use, with a minimum each week. Select Start and add a card. You can add an optional starting usage balance in the same checkout ($10 minimum).
Starter or Growth — a fixed monthly allowance of every service. Choose Monthly or Annual — save up to 25%, then select Continue to checkout.
Enterprise — sales-assisted. Select request a demo. When your agreement is ready, Billing shows Your Enterprise agreement is ready — select Review and subscribe.
Just use the free Sandbox for now — keep building without a plan.

Paying on Stripe

Continue to checkout opens Stripe Checkout, a secure payment page:

Check the plan and price. Tax is calculated from your billing address and shown before you pay.
Enter your email, card and billing address (and a tax ID if your business has one).
Select Subscribe (or Pay).
Stripe sends you back to Billing, which shows your plan.

Invoices are emailed to you by Stripe.

Your usage balance

Your plan includes a monthly allowance of every service. Usage beyond it is paid from your usage balance.

Top up: under Usage balance, enter an amount (USD $10–$10,000, plus tax) and select Add funds.
Alarms: set Email me when my balance drops below ($) and …and when any allowance is this % used, then select Save alarms. Alarms go to the owner and everyone who can manage billing.
See where it went: This month's allowance, Where your usage went (last 30 days) — by service, by Merchant or by day — and Balance history.

If production access is paused

If your allowance is used up and your balance goes below zero, production API access pauses: live (sk_live_) keys get an error, while reads and calls that finish or unwind existing trades keep working, and sandbox keys are unaffected. Top up or upgrade — access comes back within a minute.

Change your plan

Select Change plan:

Upgrade now (prorated) — takes effect immediately. You pay the prorated difference, your new allowance starts now, and any negative balance is settled on the same invoice.
Switch at renewal — a downgrade takes effect at your next renewal.

Cards

Pay-As-You-Go needs a card on file before Monday's invoice: select Add a card (or Replace card). This opens Stripe's secure page.

Space earnings

Space earnings at the bottom of Billing is money already paid out to you as a Space host, net of TBBN's commission — not something you owe.

Common questions

A payment failed. Stripe retries it and emails you. Update your card with Replace card. For Pay-As-You-Go, a failed weekly charge can interrupt production access until it's paid; sandbox keeps working.

Do I need a plan to host Spaces? No.

Where's my invoice? Stripe emails each invoice. For a statement of what you used, open account.tbbnetwork.com → Overview → Billing for the Business.
