Is there any subscription management software which is completely free?

Good subscription management software is never free. You can consider buying software – in which case you're looking at a one-time cost.

Another option is to use an online service like sendgrid or sendinblue – they will give you a free ‘quota' after which you need to pay.

So the consideration is more on the lines of:

1. Pay one time upfront and manage it yourself – like Sendy
2. Take something that's free upfront but will likely become a HEFTY billable once your userbase grows – like Sendgrid or Sendinblue
3. Take a fixed-rate monthly subscription service – like Mailmule

My experience: I had to make the same consideration a little while back for one of my customers (I consult) – and I chose to go with mailmule. The rates are awesome, support is awesome.

Hope that helps!

I don’t think there is any subscription management software which is completely free, but yes there is some billing software that is pocket-friendly.

I found a blog which I want to share with you:-

Cheapest Recurring Billing Software

The blog compiled cheap subscription management software that will help you to choose the right service for your business within the budget.

I hope this helps you.

Yes, there is a software named AZIMIO that is free for lifetime and I found that it is OK to use a free software to manage the subscription business.

This AZIMIO software offers all the features like dunning management, payment gateway integrations, plan management, API, customer portal etc. that the paid subscription software does.

This is the best option for those who have just started their business or who don't have a large amount to invest in the paid subscription software, they can go with this.

Otherwise, you want a good price high-quality service for your business, then my vote goes for Recurly. It is the best subscription management tool I have ever found.
