First, cover the landlord if you can: a late or short rent payment usually lands on whoever signed the lease. Then talk to your roommate directly, with the facts: the amount, the due date, and when they can pay. If it keeps happening, write down a plan (a new date, a smaller payment now) and look at your lease and local tenant rules. To stop it next month, set a due date before the landlord's and make who has paid visible to the whole house, which is how TableCash works.
Landlords generally want one full payment. If the lease is in your name, or you all signed one lease together, the landlord can often hold any tenant responsible for the whole rent, not just their room. So if you can cover the gap, it's usually cheaper than a late fee or a mark on your rental history. Write down what you covered and when.
Look at your lease and any roommate agreement you signed. If the roommate isn't on the lease, your options differ from when they are. Local tenant rules decide what you can do next; a local tenant's rights group or legal aid office can tell you where you stand. Small claims court is how many people recover money a roommate agreed to pay. This is general information, not legal advice.
If you're still setting up the house, write the late-rent rule into the roommate agreement before anyone moves in.
You run the house. Everyone else just opens a link.
