VisitInvoice Ninja vs Miru
What both publish
| Fact | Invoice Ninja | Miru |
|---|---|---|
| API | A REST API is available on Pro and Enterprise plans under the /api/v1 namespace. | Miru exposes a REST API with CRUD operations for time entries, invoices, clients, projects, expenses and payments using bearer-token authentication. |
| Client portal | Clients receive a branded portal for invoices, payments, documents, saved payment methods and e-signature or approval workflows. | A client portal lets customers view invoice information and pay through secure links without creating a Miru account. |
| Integrations | Invoice Ninja connects to Zapier, Make, Pabbly, n8n, Integrately, Gmail, MSN, QuickBooks, Slack, Mailchimp, Yodlee and GoCardless. | Official pages identify Stripe payments, QuickBooks Online export or sync, SMTP email, CSV and PDF export, Zapier, Make and n8n connectivity. |
| Invoicing | Users can create branded invoices and quotes with product libraries, customizable templates, custom numbering, deposits, partial payments and bulk emailing. | Miru generates invoices from tracked hours, supports line items, taxes, discounts and branded PDFs, and emails invoices to clients. |
| Licence | The source code is distributed under Elastic License 2.0, which permits business use and modification but restricts competing hosted resale; it is source-available rather than OSI open source. | The project is released under the MIT licence and the hosted feature set is stated to be present in the open-source version. |
| Maker | LinkedIn lists Invoice Ninja as privately held, founded in 2014, headquartered in Fort Myers, Florida, with 2–10 employees. | Miru is built and open-sourced by Saeloun, a Ruby on Rails consultancy with 50+ engineers that says it ships from India. |
| Payments | The service supports one-click client payments, recurring billing, ACH or bank transfers and gateways including Stripe, PayPal, Square, GoCardless, Authorize.net and Mollie. | Clients can pay invoices through Stripe Checkout, after which Miru records the invoice as paid. |
| Security | Invoice Ninja states that its hosted platform has SOC 2 certification, PCI-DSS and GDPR compliance, TLS 1.2+ in transit, AES-256 at rest, MFA, role-based access and audit logging. | The security page says hosted data is encrypted at rest and in transit, with TLS 1.3 connections and AES-256 encryption for stored data. |
| Self-hosting | Self-hosted deployments are offered through manual server installation, Docker or Podman, Cloudron, Softaculous, Elestio and YunoHost. | The self-hosting documentation covers Docker, environment variables, PostgreSQL, email delivery and Linux production deployment. |
