Wave
Wave free SMB accounting and invoicing
Wave is the free-tier-generous SMB accounting platform — invoicing, accounting, banking, payments at no cost for the core features (revenue model from payment processing fees and payroll add-on). Tiny Command exposes two actions, no triggers (Wave emits webhooks for invoice events configured in admin; point at a Tiny Command webhook trigger URL): Create Invoice (new invoice for a customer with line items, taxes, due date), List Customers (every customer in the business). The connection uses Wave OAuth. For solo consultants, freelancers, and very small businesses that want free invoicing + accounting without paying for QuickBooks/Xero/FreshBooks, Wave is the right pick. The trade-off is fewer enterprise features (no time tracking, limited reporting, US/Canada-focused). For workflows that auto-generate invoices on project completion or sale, Wave + Tiny Command is a powerful free combo.
Do anything Wave can do, from a workflow.
Every action accepts dynamic inputs from upstream nodes, whether that's an AI output, a form field, or a search result.
| Action | What it does |
|---|---|
| Create Invoice | Creates an invoice in Wave via the GraphQL invoiceCreate mutation, with customer, line items, taxes, and due date. Used to invoice on milestone completion or to mirror billable activity from another system. |
| List Customers | Lists customers in Wave using the GraphQL API, scoped to a business ID. Use to populate a customer picker or to keep your CRM and Wave in sync. |

Three things worth knowing.
Tiny Command counts a run the moment a trigger fires. Filtering early means only matching events spend your usage budget.
Connect Wave once and every workflow on your account can use its triggers and actions. You don't have to re-auth per workflow.
Every Wave field shows up in the visual picker for downstream nodes. The raw payload is there for power users, optional for everyone else.
