Three housemates split a takeaway order, agree who owes what, and then the message about who needs to pay up gets lost in a group chat nobody checks anymore. Splitwise already knows the moment a new expense is created and who is on the hook for it, so instead of waiting for someone to open the app and notice a balance, a text can land on their phone straight away.

Connected through Zapier, Splitwise can push each new expense straight into Mobile Message, so a text goes out the moment the bill lands rather than whenever a friend happens to check their notifications. The same connection works the other way too, a reply that comes in through Mobile Message can be turned into a new expense in Splitwise, so a quick text is enough to get a cost logged and split without opening the app at all.

For anyone who organises shared costs for a house, a trip or a regular group, this turns a habit of chasing people up into something that happens on its own. The group still settles up inside Splitwise, the text is just there to make sure nobody forgets there is a balance sitting on their name.
