# Invoice Ninja [](https://travis-ci.org/invoiceninja/invoiceninja) [](https://invoice-ninja.readthedocs.io/en/latest/?badge=latest) ## [Hosted](https://www.invoiceninja.com) | [Self-Hosted](https://www.invoiceninja.org) ### We're on Slack, join us at [slack.invoiceninja.com](http://slack.invoiceninja.com) or if you like [StackOverflow](https://stackoverflow.com/tags/invoice-ninja/) Just make sure to add the `invoice-ninja` tag to your question. #### Note: v5 is now tagged Stable! To upgrade from v4 you need to [install v5](https://invoiceninja.github.io/docs/self-host-installation/) as a separate app and then use the migration tool in the latest version of v4 on Settings > Account Management. All Pro and Enterprise features from the hosted app are included in the open-code. We offer a $30 per year white-label license to remove the Invoice Ninja branding from client facing parts of the app. The self-host zip includes all third party libraries whereas downloading the code from GitHub requires using Composer to install the dependencies. * [Features](https://www.invoiceninja.com/invoicing-features/) * [Videos](https://www.youtube.com/channel/UCXAHcBvhW05PDtWYIq7WDFA/videos) * [User Guide](https://docs.invoiceninja.com/) * [Support Forum](https://www.invoiceninja.com/forums/forum/support/) * [StackOverflow](https://stackoverflow.com/tags/invoice-ninja/) ## Mobile App * [iPhone](https://apps.apple.com/us/app/invoice-ninja-v5/id1503970375#?platform=iphone) * [Android](https://play.google.com/store/apps/details?id=com.invoiceninja.app) * [Linux](https://github.com/invoiceninja/flutter-mobile) ## Desktop App * [MacOS](https://apps.apple.com/app/id1503970375) * [Windows](https://microsoft.com/en-us/p/invoice-ninja/9n3f2bbcfdr6) * [MacOS Desktop](https://snapcraft.io/invoiceninja) ## Installation Options * [Ansible](https://github.com/invoiceninja/ansible-installer) * [Self-Host Zip](https://invoice-ninja.readthedocs.io/en/latest/install.html) * [Docker File](https://hub.docker.com/r/invoiceninja/invoiceninja/) * [Cloudron](https://cloudron.io/store/com.invoiceninja.cloudronapp.html) * [Softaculous](https://www.softaculous.com/apps/ecommerce/Invoice_Ninja) * [Lando](https://github.com/invoiceninja/invoiceninja/issues/2880) * [Yunohost](https://github.com/YunoHost-Apps/invoiceninja_ynh) ## Recommended Providers * [Stripe](https://stripe.com/) * [Postmark](https://postmarkapp.com/) ## Development * [API Documentation](https://invoice-ninja.readthedocs.io/en/latest/api.html) * [PHP SDK](https://github.com/invoiceninja/sdk-php) * [Laminas Framework](https://github.com/alexz707/InvoiceNinjaModule) * [Custom Module](https://invoice-ninja.readthedocs.io/en/latest/custom_modules.html) | [Watch Video](https://www.youtube.com/watch?v=8jJ-PYuq85k) ## Third Party Modules * [Event Scheduler](https://github.com/cytech/Scheduler-InvoiceNinja) * [Manufacturer Module](https://github.com/dicarlosystems/manufacturer-invoiceninja) * [Point of Sale](https://github.com/dicarlosystems/pointofsale-invoiceninja) * [Invoice Design Import/Export](https://github.com/feyst/invoicedesignexport) > Feel free to email us for help if you're working on a module, we're happy to provide developer support. ## Third Party Tools * [InvoicePlane Import](https://github.com/turbo124/Plane2Ninja) * [Toggl Sync](https://github.com/Matth--/toggl-invoiceninja-sync) * [Shopping Cart](https://github.com/Scifabric/invoiceninjashoppingcart) ## Third Party Developers * [Bold Compass](https://boldcompass.com/customize-invoice-ninja/) ## Contributing All contributors are welcome!
