Here’s an idea, being able to pay for a meal/shop and afterwards, being able to split the spend with other friends who use Monzo.
Monzo sends a notification to the friends phone, the friends can accept the split spend, and money will be taken out of their account accordingly and transferred the the payee.
A simple split would divide the spend equally. A more detailed option could be used to split according to who bought what. This would require inputting values.
If a friend doesn’t have Monzo a invite message could be sent to the friend, also with an IOU message. ‘You owe bill £15.80’ calculated by Monzo as mentioned. The user can pay this in cash or join Monzo and pay through the app.
This idea’s one of the features that are up next on the roadmap so it’ll be interesting to see how similar Monzo’s solution is to the one you’ve described
