Wallet

The Wallet is your balance of purchased AI credits — the credits you buy on top of what your plan includes. Buying an AI credit pack is what tops up the Wallet. Knock Knock App draws from it for telephony — renting phone numbers and paying for calls — and as a backup for AI usage when your plan's included credits run out.

info

Your plan's included AI credits are AI-only — they never pay for telephony. Phone numbers and calls are funded solely from the Wallet (purchased credits). See AI Credits Usage for how plan credits work.

Your Wallet Balance​

The Wallet holds your purchased credits, where 1 credit = $0.01. Unlike plan credits, purchased credits don't reset with your billing cycle — they stay in the Wallet until spent. Your balance appears as a Wallet pill in the main sidebar, so you can always see how much you have left. Click the pill to top up.

If your account is managed by an agency, it may start with an opening transfer from the agency's wallet, and the agency can send further credits at any time. See Managing Companies.

When your balance gets low, the Wallet pill turns amber — a visual nudge to top up before anything gets interrupted.

Wallet Statement​

To review where your credits are going, open Packages & Billing → Wallet. The page is one statement, newest first:

  • Calls, chats and AI tasks — each call, chat conversation or AI task is a single line with what it cost (calls also show their length). Click View to open its breakdown — the separate charges that made it up.
  • Top-ups and transfers — credits you added, auto-recharge, and transfers from your agency.
  • Other charges — for example monthly number rental, or a charge that doesn't belong to one call or chat.

Use the dropdown to show Everything, Calls, chats & AI usage, Top-ups & transfers, or Other charges. Charges under 1¢ are hidden until you tick Show items under 1¢. New calls, chats and AI tasks appear within a few minutes.

The tiles above the list show your Current wallet, Total added, and Total spent. AI usage is billed hourly, so a recent line can be marked Pending — it is charged at the next hourly billing, from your plan credits first and then the Wallet. Because plan credits are spent first, a line's cost is what the activity used, not necessarily what came out of your Wallet balance.

If charges land while your balance is empty, the balance can go negative — your next top-up settles it first.

note

On accounts where the per-activity statement is switched off, the page shows the older Wallet transactions list instead: one row per wallet movement (When, Description, Amount, Balance) with a filter by type — top-ups, auto-recharge, agency transfers, number rental, calls, text messages, AI usage and each Agent K step.

Your balance, plan and subscription update on screen as soon as they change — a top-up, an auto-recharge, or a change made by your agency or the Knock Knock team shows without refreshing the page.

Agent K Charges​

When Agent K is enabled, its data lookups are billed from the Wallet as itemized line items — one transaction per step, at the per-step prices shown in the pricing table before you turn Agent K on. A call to a data provider that fails costs nothing, but searches and on-demand lookups are charged per attempt, whether or not they find anything — see Agent K billing.

The connected LinkedIn seat is also billed here — once when you connect, then monthly while it stays connected. If the Wallet can't cover a renewal, the LinkedIn account is disconnected immediately (you get a heads-up email the day before if your balance won't cover it). Top up and reconnect to resume.

How Phone Numbers Are Billed​

Phone numbers you buy inside the app (see Call Agent) are billed from your Wallet:

  • The first month is charged at the moment of purchase.
  • After that, rent is charged monthly from the Wallet on the number's billing anniversary.

Low-Balance Bar​

When your balance runs low, a bar across the top of the app says so — "Your wallet balance is low — $3.20 left (about 4 days). Visitor identification and AI calls will pause at $0." — with Add funds. The days estimate is your balance over your average daily wallet spend in the last 7 days (left out when there's no recent spend). It follows the same rule as the low-balance email below: below $5 (or your auto-recharge threshold), on a wallet that has been in use, and not when a working auto-recharge will top it up. It can't be dismissed — it clears as soon as you top up. At $0 the "AI is paused" bar takes over.

If your agency funds your account and you have no card of your own, the bar asks you to contact your agency instead of offering Add funds.

Agencies get a matching bar in the agency portal for clients whose wallets are low or empty: one client is named with a Top up button right there; several are rolled into one bar with Review wallets. Only agency staff with billing access see it.

Low-Balance Emails​

The account owner gets an email when the Wallet drops below $5 — or below your auto-recharge threshold, if you've set one — ("Your wallet balance is running low"), and another when it reaches $0 ("Your wallet is empty"). Each is sent once per dip and re-arms when you top back up. If auto-recharge is on and working, you get its own emails instead. For an agency-managed account, your agency is told as well.

What Happens When the Wallet Runs Dry​

If your Wallet cannot cover a number's monthly rent:

  1. Warning emails — you receive reminders to top up, around day 3 and day 6.
  2. Suspension — the number is suspended. Rent stops accruing while the number is suspended.
  3. Incoming calls declined — while your balance is empty, incoming calls to app-purchased numbers are declined, and callers hear that the number is temporarily unavailable.
  4. Release — after roughly 7 days, a suspended number is released and is no longer yours.

Topping up in time un-suspends the number automatically — no support ticket needed.

note

Only numbers purchased through the app can be suspended or released. Numbers you brought yourself — connected from your own telephony account — are never suspended or released by the Wallet.

Agency-Managed Accounts​

If your account is managed by an agency, the Wallet works the same as for any other account. You always see the Wallet, you can spend from it — buying phone numbers and making calls — and you can top it up yourself with your own card.

Your agency can also switch on auto-recharge for your Wallet, funded from its own wallet: when your balance drops below the amount it set, it adds a set amount automatically. The auto-recharge card on the Add-ons page then reads "your agency adds … automatically" and has no Manage button — only your agency can change or switch it off.

If your agency sells Wallet balance at its own price, top-ups are charged by your agency (through its own payment account) and each dollar you top up goes a little less far — your agency sets the rate.

For agency-managed accounts, the Packages area shows four tabs: Your Plan, Wallet, Add-ons, and Payment Methods. Add a card under Payment Methods to top up and buy add-ons — you don't need to go through your agency. Plan and subscription changes, however, remain with the agency.
