This is my personal project that I worked on. It is a complete SaaS. Using this web app a the User can send SMS and the hotel on the other end, this was meant for use with hotels and their customers, will receive these as push notifications on the site.

What's included to make this all work, and technologies include:

• Twilio for SMS messaging, purchasing of a local phone number for the hotel, use of Twilio Subaccounts for billing
• Stripe for payments
• Payments are structured as "pay as you go", so the customers of this SaaS refill when out of funds. This can be done automatically if "recharge" account is turned on.
• Monthly fees for active phone numbers do occur, so this uses cron with Django custom management commands to make that happen.
• Redis is used for the push notifications, and to keep track of recent messages in case an account recharge is needed, instead of querying the database to see how many SMS have been sent
• Celery is used for sending of SMS and as email, so as not to affect the performance of the site. Celery uses RabbitMQ as it's message broker, and Redis as it's data store.

The site is built using Python2 and django-websocket-redis. I would rebuild in Python3, and use django-channels.
