Payment method w/M to M lease

[Austin Albright]

Good morning all, 

Bought a house last year, moved in two friends to house hack. Was new to this mindset. One paying via bank transfer (we have the same bank and I trust him), the other paying via Venmo. They are both on month to month rental agreements. Now that I am trying to treat this more more like a business I've decided to switch over to Innago for payment processing. 

I notified them both two weeks ago that this change is happening. One of the tenants completely ignored me and has yet to talk to me. Context: long time friend, he is the sightly paranoid type (doesn't like online banking, loves routine and hates change). I have messaged him multiple times over the last two weeks and he continues to ignore me and hide out in the basement (his rented portion.) 

I'd like some input on how to deal with this. Ultimately I think I might have to put my foot down and say look if I need to end your rental agreement I will. Agree to the change or move out. I would hate to have to do this as it would likely ruin our friendship, I'm having a hard time finding other options. Please advise. Thank you for your time, have a beautiful day.
