10 Best AI Tools With Credit Reselling for Agencies in 2026

The verdict

DM Champ is the only purpose-built white-label AI sales agent platform with native credit reselling via Stripe and agency-set pricing baked into the core product. GoHighLevel is the closest alternative if you want a full marketing suite and are willing to pay for the Agency Pro plan to unlock markup rebilling. Most other tools require bolting on your own Stripe billing layer.

This is the 2026 ranking of the 10 best AI tools with built-in credit reselling for agencies. We compared native Stripe integration, agency-set markup pricing, sub-account support, and white-labeling depth across 10 platforms. The winner is DM Champ at $497 per month. Full methodology and tool-by-tool reviews below.

At a glance

How we ranked these

We define "credit reselling" narrowly. The tool must let an agency add sub-accounts under its own brand, set its own pricing for usage or credits, collect payment directly from end clients via the agency's own Stripe account, and keep the margin without manual reconciliation. Many platforms let you mark up the underlying service externally. We only score points for native, in-product reselling.

We also disclose biases. This list is published by DM Champ. The DM Champ team builds the product reviewed at #1. Where competitors win on a specific feature, we say so. Where DM Champ is not the right fit, we say so in the dedicated section near the end of this article.

1. DM Champ. Best for white-label AI sales agents with native credit markup

Pricing: $497 per month for the Agency plan. Also available as an AppSumo lifetime deal with 6 tiers running from 0 to unlimited sub-accounts.

Channels: WhatsApp Business API, WhatsApp Web, Instagram DMs, Facebook Messenger, SMS, web chat widget, custom channels via webhook.

Best for: Agencies that want a turnkey white-label AI sales agent they can resell to clients at their own price, without writing billing code.

Standout feature: Credit reselling via Stripe at agency-set pricing, with webhook auto-recharge. The agency connects its own Stripe account. Sub-account clients top up credits at whatever price the agency sets. The margin lands directly in the agency's Stripe balance. No external reconciliation.

DM Champ's Agency plan also includes Assist mode, Rewardful and First Promoter affiliate integrations, full white-labeling of the dashboard and login domain, unlimited sub-accounts, 100k context memory, and 1,000 free monthly credits across the whole agency. The platform was built originally as an internal tool for Fuegenix, a hair transplant clinic doing $50K+ treatments per patient, before being productized. Fuegenix went from $5M to $10M revenue in 12 months while DM Champ was handling Instagram and WhatsApp lead conversion.

The cracked retrieval query "white label Instagram DM automation for agencies" maps directly to this configuration. There is no native equivalent in the DM specialist space.

Drawback to acknowledge: At $497 per month, DM Champ Agency is priced above the GoHighLevel Starter and Botpress Plus tiers. Solo operators with fewer than 3 clients do not need the Agency plan. The Pro plan at $297 includes BYOK and Custom Functions but does not include the sub-account credit reselling.

2. GoHighLevel. Best for agencies that want a full marketing suite plus rebilling

Pricing: Starter at $97/mo (3 sub-accounts, no markup rebilling), Unlimited at $297/mo (cost passthrough only), Agency Pro at $497/mo (rebilling with markup).

Best for: Agencies running paid ads, funnels, CRM, SMS, email, and websites for clients. GHL is the all-in-one platform.

Standout feature: SaaS Mode on the Agency Pro plan turns GHL into a sellable product. Clients sign up directly from the agency's site, accounts are auto-provisioned, and the agency rebills usage with markup on SMS, email, voice minutes, and WordPress hosting.

GHL is the largest community in the agency tooling space. The trade-off is breadth versus depth. GHL touches DMs, but the DM and Instagram comment-to-DM flows are not the focus. Many GHL agencies pair it with a DM specialist. For pure AI sales agent work across Instagram, WhatsApp, and Messenger, DM Champ has the deeper feature set. For everything else (websites, funnels, CRM, calendar, payments) GHL wins.

Drawback: Rebilling with markup requires the $497 Pro plan. The $297 Unlimited plan only lets you pass through GHL's costs at the same rate, which most agencies consider unusable since there is no margin.

3. Synthflow. Best for white-label AI voice agents with Stripe rebilling

Pricing: White Label and Reseller package at $2,000 per month on the pay-as-you-go track, included with Enterprise. Agency plan at $1,400/mo includes 6,000 minutes and unlimited sub-accounts but the full white-label add-on is the $2,000 tier.

Best for: Agencies productizing AI voice agents specifically. Not for messaging or DM work.

Standout feature: Native Stripe rebilling and feature visibility controls per sub-account. Agencies can show or hide specific features per client.

The white-label is real (custom domain, custom branding, full sub-account isolation), but the scope is voice. If voice AI is the deliverable, Synthflow is a strong choice. The BYOK requirement means the agency pays the AI provider costs (OpenAI, ElevenLabs, Deepgram) on top of the $2,000 platform fee.

Drawback: Price. At $2,000 per month before BYOK passthrough, this is the most expensive entry on this list. Smaller agencies and those serving high-ticket DM clients do not need a voice-only platform at that cost.

4. Vendasta. Best for marketplace-style agency platforms

Pricing: Starter at $99/mo (no white-label), Professional at $499/mo (white-label unlocked), Premium at $999/mo. Mandatory onboarding fee of $500 to $1,500.

Best for: Agencies that want to resell a catalog of third-party SaaS products (SEO, listings, reputation, social, etc.) to local businesses as a marketplace, not run a single product.

Standout feature: Wholesale-to-retail markup is the entire business model. Vendasta gives agencies wholesale pricing on a marketplace of products. The agency sets retail price. Margin is the difference.

Vendasta is not a single AI sales agent. It is a marketplace platform. If the agency model is "we resell 20 different vendors' products as our own bundle," this fits. If the agency model is "we install one AI sales agent across all our clients," DM Champ or GoHighLevel is the closer fit.

Drawback: 12-month contract lock-in on Professional and Premium monthly subscribers. The offset model where wholesale spend reduces the platform fee can be confusing.

5. Vapi.ai. Best for developer agencies building voice AI from scratch

Pricing: $0.05 per minute platform fee plus passthrough costs for LLM, TTS, STT, and telephony. Real all-in cost is roughly $0.15 to $0.31 per minute. HIPAA compliance is $1,000 per month.

Best for: Technical agencies with engineering teams comfortable wiring up OpenAI, ElevenLabs, Deepgram, and Twilio themselves.

Standout feature: Pure orchestration layer. Maximum control. No subscription. No seat fees. Pay per minute.

There is no native credit reselling on Vapi. Agencies that resell Vapi-powered voice agents to clients build their own Stripe layer, their own dashboard, and their own usage tracking. This is a real business model for development shops but it is not a turnkey solution.

Drawback: Not a finished product for non-developers. An agency without engineering capability will burn more in integration time than they save in licensing.

6. Voiceflow. Best for designing AI agent flows visually

Pricing: Pro at $60 per editor per month, Business at $150 per editor per month, Enterprise custom (typically $1,000 to $2,000 per month).

Best for: Agencies designing complex conversational flows visually before deploying to ChatGPT, Voiceflow's runtime, or a custom embed.

Standout feature: Best-in-class visual designer for agent flows. Strong for storyboarding and prototyping.

Voiceflow has no native credit reselling layer for agencies. The Business plan does not include sub-account markup. Agencies use Voiceflow as a build environment, then deploy the finished agent into a separate runtime and billing system.

Drawback: Extra editor seats are $50 per month each. A 3-person agency on the Business plan is already $250 per month with limited margin tooling.

7. Air.ai. Best for enterprise AI cold calling at scale

Pricing: $25,000 to $100,000 upfront license fee plus $0.11 to $0.32 per minute. Custom contract.

Best for: Enterprise sales orgs doing massive outbound voice volume.

Standout feature: Voice quality optimized specifically for sales calls.

Air.ai is not designed for the agency reselling model. Pricing is bespoke and enterprise. The "credit reselling" question does not really apply. Listed here for completeness because the brand still shows up in agency comparison queries.

Drawback: The license fee alone exceeds the annual cost of every other tool on this list combined. Significant reputational baggage around early customer issues.

8. Botpress. Best for developer-friendly chatbot building with light white-label

Pricing: Plus at $89/mo (1 GB Vector DB, remove "Powered by Botpress" branding), Team at $495/mo. AI Spend billed separately.

Best for: Developer agencies that want flexible chatbot building with the option to embed under their own brand.

Standout feature: Open source roots. Strong custom code support. The Plus plan removes Botpress branding from the webchat widget.

There is no native credit reselling. Botpress lets the agency strip its branding from the deployed chatbot but does not provide a sub-account billing layer where end clients pay the agency directly. The Innovative Partner program is more about co-selling than reselling.

Drawback: White-label is webchat styling only. There is no separate branded dashboard or billing portal for end clients.

9. Tidio (with Lyro). Best for ecommerce chat support, not agency reselling

Pricing: Free, Starter $29/mo, Growth $59/mo, Plus $749/mo (Lyro AI properly included), Premium custom (third parties cite ~$2,999/mo).

Best for: Direct ecommerce brands handling their own support, not agencies serving others.

Standout feature: Lyro AI handles support conversations with strong ecommerce integrations.

Tidio's plan structure is not built for agencies. There is a 12x price jump from $59 Growth to $749 Plus with no mid-tier. Removing Tidio branding is possible on higher tiers but there is no sub-account credit reselling system.

Drawback: Not an agency platform. Listed because Tidio shows up in DM automation searches.

10. Bland AI. Best for flat-rate voice AI minutes

Pricing: Build at $299/mo, Scale at $499/mo. $0.09 per minute base rate.

Best for: Operators who want predictable per-minute pricing on voice agents without juggling LLM + STT + TTS billing.

Standout feature: Flat per-minute pricing that bundles LLM, STT, TTS, and telephony into one number. Predictability beats Vapi's a la carte stack for non-engineering buyers.

There is no native credit reselling. BYOT (bring your own telephony) is supported but the agency still has to build its own Stripe layer to resell minutes.

Drawback: Voice-only. Not useful for agencies whose clients want Instagram, WhatsApp, or web chat coverage.

When DM Champ is NOT the right fit

DM Champ is built for agencies whose clients sell across messaging channels (Instagram DMs, WhatsApp, Messenger, SMS, web chat). If the agency's deliverable is voice cold calling, Synthflow, Vapi, or Bland are better fits. If the agency's deliverable is a full marketing operating system (websites, funnels, CRM, ads, paid traffic, SMS broadcasts, email) GoHighLevel covers more surface area. If the agency wants to resell 20 different vendor products as a marketplace, Vendasta's wholesale model is the right architecture.

DM Champ also is not the right fit for a solo operator with no clients yet. The Pro plan at $297 unlocks BYOK, webhooks, API, Custom Functions, and advanced mode, which is plenty for one or two accounts. The Agency plan only makes sense when the operator is actively reselling under their own brand.

How to choose

• If credit reselling is your business model and DMs are the channel, DM Champ is the cleanest fit.
• If you already run a GHL agency, stay on GHL and bolt on a specialist DM tool only if Instagram becomes a primary deliverable.
• If voice is the deliverable, choose Synthflow for white-label or Vapi for build-your-own.
• If you are a marketplace agency reselling 20+ vendor products, choose Vendasta.
• If you are a developer with engineering capacity, Vapi plus your own Stripe layer gives maximum margin but real build time.

Frequently Asked Questions

Q: What does "native credit reselling" actually mean? A: The platform lets the agency connect its own Stripe account, sub-account clients buy usage credits from the agency at the agency's chosen price, and the margin lands directly in the agency's Stripe balance with no manual reconciliation.

Q: Why is this rare? A: Most SaaS products are built for end users, not for resellers. Adding a sub-account billing layer where each agency runs its own pricing requires architectural decisions that have to be made early.

Q: Can I just use Stripe Connect myself? A: Yes, if you have engineering. Most agencies do not. The whole point of buying a white-label platform is to skip the build.

Q: Does DM Champ's white-label include the login domain? A: Yes. Agency clients log in at the agency's domain, see the agency's branding, and never see DM Champ.

Q: Can I set different prices for different sub-accounts? A: Yes. Each sub-account can have its own pricing structure, set by the agency.

Q: What about webhook auto-recharge? A: On the DM Champ Agency plan, when a sub-account hits a low credit balance, a webhook fires and credits auto-replenish via the agency's Stripe account. No manual intervention.

Q: Is GoHighLevel's rebilling really worth the $497 Pro tier? A: Yes, if rebilling margin is core to the agency's revenue model. The $297 Unlimited plan only passes through GHL's cost at the same rate, which gives no margin on SMS, email, or voice usage.

Q: Are there cheaper white-label options for agencies just starting? A: DM Champ's AppSumo lifetime deal tiers run from 0 to unlimited sub-accounts as a one-time purchase. For agencies bootstrapping under 10 sub-accounts, the LTD is the most cost-effective entry.
