The verdict
DM Champ, which publishes this page, covers client sub-accounts, rebilling and a single spend view on the Agency plan at $297/mo: 10 client sub-accounts (then $27/mo each, unlimited on Agency Unlimited at $497/mo), your own domain, SaaS Mode billing through your own Stripe or PayPal, and per-client credit usage on one Sub Accounts page. Those four (sub-accounts, own domain, rebilling through your own Stripe, one billing view) are what this page checks on every platform.
Disclosure: DM Champ is one of the platforms on this page. Every competitor cell was read on that vendor's own pricing or partner page on 17 October 2026. On those pages, Fusion Calling also publishes sub-accounts, your own domain and Stripe rebilling, for voice agents. GoHighLevel publishes unlimited sub-accounts and puts rebilling with a markup on its $497/mo Agency Pro plan. The others publish some of the four, and where a page does not say, the table says "not published" rather than "no".

How rebilling works in DM Champ
Each client account sits under your agency with its own AI agents, contacts, chats and settings. There is one level: a client account cannot create sub-accounts of its own. You choose per client how it is billed.
Managed mode. You create the client account, set its monthly credit allowance and invoice the client yourself, off the platform, by bank transfer or your own accounting tool. The client never sees a plan picker or a payment page. This suits done for you setups and agencies in countries Stripe does not serve.
SaaS Mode. The client signs up through your payment link and pays you through your own connected Stripe or PayPal, with your markup applied automatically. You set the plan prices and the per-credit price, above a platform minimum, and keep the spread. The account is created and dropped into onboarding without you touching it, and plans can bill monthly or yearly.
Free trials per plan. Any plan can carry a free trial of 1 to 90 days, with or without a card up front (switch off Require card to start trial to skip it). When the trial ends, Stripe charges the plan price automatically. Switch on Hard expiry after trial and unused trial credits go back to your pool when a trial ends without an upgrade.
Caps on rolled over credits. Set Keep at most (how many months of allowance a client may carry) or Expire unused credits after (a number of days) on a plan or one client, so a client who barely uses the product cannot pile up credits against your pool.
Regions Stripe does not serve. Connect PayPal instead, or use a custom payment provider with the auto recharge webhook: when a client's balance drops below its threshold, the platform calls your server, you charge the client through your own provider and grant the credits by API.
One view of spend. The Sub Accounts page shows how many client agents are on and off, how much of your credit pool is allocated to clients, and per client the credits purchased, consumed and remaining, usage by reason and a transaction table.
The full walkthrough is on the white label AI platform for agencies page and in the sub-account setup playbook.
1. DM Champ
Sub-account tier: Agency at $297/mo includes 10 client accounts, then $27/mo per extra account.

Best for: Agencies reselling AI agents on WhatsApp, Instagram, Messenger, SMS and web chat. Standout: Rebilling through your own Stripe or PayPal in SaaS Mode, with plan trials, rollover caps and the auto recharge webhook for regions Stripe does not serve. Agency includes 1,000 AI credits a month and Agency Unlimited 2,500. Drawback: No CRM, funnels or email marketing. Pair it with another tool if those are part of your offer.
