Billing, balance, and token usage.

DEF runs on AI tokens. Every time your agent reads a message, classifies it, generates a reply, or writes a Wiki page, it uses a small amount of token credit from your balance. Your balance is pre-loaded and drawn down as DEF works.

Where to find your balance

Open Settings → Billing. You see your current balance in USD, your usage over the last 30 days, and your last few top-up receipts.

A typical operation burns $20 to $80 per month on token usage. The exact number depends on how much your agent talks (more guests = more tokens) and how often you use the board chat to ask questions.

Auto-topup

When your balance drops below a threshold you set (default $20), DEF auto-charges your card for a top-up amount you set (default $40). The agent never stops because of an empty balance, unless auto-topup is off or the card fails.

You can turn auto-topup off and manage top-ups manually, but most owners leave it on.

Manual top-up

Click Add credit on the Billing page. Pick an amount, pay through Recurrente (the payment processor), get a confirmation, balance updates instantly. You can also pre-load a quarter's worth in advance to avoid thinking about it.

What happens if it runs out

If auto-topup is off and your balance hits zero, the agent pauses non-essential work. Critical paths stay alive — incoming guest messages still get acknowledged and logged. But classification, delegation, and proactive features pause until you top up.

DEF pings you on WhatsApp before the balance hits zero, and again when paused. You won't be surprised by it.

What you pay for vs. what's included

The flat monthly fee for your DEF install covers the platform, the integrations, the maintenance, the support. The token balance covers the actual AI usage on top. Two separate lines on your statement.

That's the course.

You've now walked through every part of DEF: the dashboard, the team setup, the agent, daily operations, configuration, and billing. From here it's practice. Run your operation through DEF for a week, come back to any lesson when you need a refresher.
