At a glance
| Invoice My Clients | Invoice Ninja | |
|---|---|---|
| Product focus | Hosted invoicing, proposals, purchase orders, time to invoice, and automated collections, with an AI assistant and MCP server on top. | Open-source invoicing, quotes, and time tracking, with a self-hosted option for teams that want to run their own server. |
| Pricing approach | Free plan, then flat monthly plans that bundle the AI allowance. See our Pricing page for current numbers. | Free self-hosted option and paid hosted plans. Check their site, published terms change. |
| AI and automation | Chat and voice assistant on Claude 5 models that creates and sends invoices, chases overdue balances, and builds reports, plus an MCP server for your own tools. | Automation through recurring invoices, reminders, and an API; AI is not the center of the product. |
| Getting paid | Stripe-powered links on every invoice: cards, ACH, Apple Pay, and Google Pay, settling to your own Stripe account. | Supports many gateways that you configure yourself, which is flexible but puts setup and upkeep on you. |
| Often the best fit | Service businesses that want collections and AI to run themselves and nobody on staff to maintain a server. | Technical teams that want to own the stack, customize the code, or keep invoicing entirely on their own infrastructure. |

Payments are Stripe-powered: cards, ACH, Apple Pay, and Google Pay through a link on every invoice, settling to your own Stripe account with no markup from us.
