Billing, Plans, and Credits

Plans overview

Macha offers four plans to match different usage levels. Each plan determines your limits for connectors, agents, data sources, triggers, and custom tools.

Trial

A free plan with limited access to explore the platform. Try out agents, connect a few tools, and see how Macha works for your team. No credit card required.

Starter

For individuals and small teams getting started with AI agents. Includes basic limits for connectors, agents, and data sources.

Professional

For growing teams that need more power. Includes higher limits across the board, plus access to scheduled triggers (up to 3) and custom tools (up to 5 assignment slots).

Enterprise

For organizations that need the highest limits and priority support. Includes up to 20 scheduled triggers, 20 custom tool assignment slots, and credit check bypass so your agents never stop due to usage limits.

Credits system

Understanding Credits & Choosing the Right AI Model

Macha uses a credit-based system for AI usage. Each time an agent completes a response, credits are deducted from your organization's balance.

How credits work

• Credits are deducted once per complete assistant response — not per tool call, not for every step in the agent's instructions. If an agent makes several tool calls before responding, you're only charged once for the final response.
• The credit cost depends on which AI model the agent is configured to use. More capable models cost more credits per response.
• You set the model on a per-agent basis, so a high-volume triage agent can run on a cheap model while a complex reasoning agent runs on a more capable one.

Choosing the right model for the job

You don't need to use the most powerful model for everything. Picking the right model per agent is the easiest way to control credit spend without sacrificing quality:

• GPT-5.4 Mini (1 credit/response) — fast and affordable. Great default for most Zendesk workflows: triage, drafting replies, summarizing tickets, updating fields. If you're running high-volume support automation, make this your default.
• GPT-5 (3 credits/response) — strong quality at a reasonable cost. Use this when an agent has long, complex, multi-step instructions that Mini struggles with. This is the platform default and a good balance for most agent workflows.
• Anthropic Claude / GPT-5.4 / others — explore these if GPT-5 isn't giving you the quality you need on a particular agent.

You can pick any model when configuring an agent. If you're not sure, click the "Which model should I use?" link on the configuration screen for quick guidance.

Enterprise credit bypass

Organizations on the Enterprise plan bypass all credit checks. Your agents will always run regardless of credit balance, ensuring uninterrupted service.

Usage alerts

Macha sends email notifications to all organization admins when your credit usage reaches certain thresholds:

• 50% used — a heads-up that you're halfway through your credits
• 80% used — a warning that credits are running low
• 90% used — an urgent alert to top up or upgrade before agents stop working

These alerts are sent once per threshold, so you won't receive duplicate emails.

Plan limits

Each plan includes limits on the following resources:

• Connectors — the number of integrations you can connect
• Data sources — uploaded documents and connected data
• Agents — the number of agents you can create
• Scheduled triggers — cron-based automated agent runs (Trial/Starter: 0, Pro: 3, Enterprise: 20)
• Custom tool slots — tool-to-agent assignments for custom API tools (Trial/Starter: 0, Pro: 5, Enterprise: 20)

Managing your subscription

To upgrade, downgrade, or manage your subscription, go to Settings and open the Billing section. From there you can:

• Upgrade your plan — click the upgrade button and complete checkout. The checkout opens directly within Macha (no external redirect).
• Downgrade your plan — switch to a lower plan. The change takes effect at the end of your current billing period.
• View your current plan — see your plan name, credit balance, and usage.
