Can a landlord use Mercury for a rental LLC's bank account?

What Mercury is and is not

Mercury describes itself as a financial technology company that offers business banking through partner banks. That matters to a landlord for two reasons. The account behaves like a modern online business account (no branch, fast sign-up, clean screens), and the protections behind your balance depend on the partner bank and on how deposit insurance works, not on Mercury itself.

Read Mercury's own pages for the current account types, fees and eligibility. Account terms change, and a blog post is the wrong place to learn a fee schedule. What a landlord should do is write down the three or four things the rental needs from a bank, then check each against the pages. The list below is a good start.

• How tenants will pay: bank transfer to an account and routing number, Zelle, check or cash.
• Whether you can open one account per LLC, so each property keeps its own money.
• What FDIC insurance covers at the balance you expect to hold. Read the FDIC's page on how coverage works for each depositor at each bank.
• Whether you can give your bookkeeper or software read-only access instead of your login.

How tenants will pay a Mercury account

A bank transfer works with any business checking account: the tenant sends money to your account number and routing number from their own bank. Tenants usually find this easy once the details are in a message they can copy. Put the unit and last name in the memo so you can tell payments apart.

Zelle is different. Zelle is offered through participating banks and credit unions, so a landlord whose bank is not a participant cannot give tenants a Zelle address for that account. Check Zelle's own list of participating banks and your bank's help pages before you promise Zelle in a lease. If your bank does not support it, tell tenants to use a bank transfer instead.

Checks and cash need a plan too. Most online-first accounts handle deposited checks through a mobile or mailed process, and cash can be hard to deposit. A landlord who still gets cash should read the bank's rules before opening the account, or keep a second account for it. A paper trail for cash matters either way, as covered in Can a landlord refuse cash for rent?.

One account for each LLC

When each property sits in its own LLC, each LLC needs its own bank account, so rent, expenses and the security deposit liability never mix between properties. Opening a business account usually asks for the LLC's legal name, its EIN, the formation papers and the operating agreement. Have those ready as files. If the LLC has two members, the bank may ask for each owner's ID.

Example a made-up owner has three single-property LLCs. Each has its own checking account, which opened at $0. In October, Maple LLC collects $4,800 of rent and pays $1,900 of expenses, so its account ends the month at $2,900. Birch LLC and Cedar LLC are untouched by those payments, and the owner can read each balance without sorting anything.

A second account for tax and insurance escrow money or for repairs is a choice, not a rule. Many owners keep one operating account per LLC and track reserves as a line in their books. Pick the setup you will actually keep clean.

Connecting the account to your books

Mercury publishes API documentation for developers, and its docs describe API tokens that can be limited to reading balances and transactions. That kind of read-only access is what a bookkeeping tool needs, because a tool that only reads can never move money. Never share your Mercury login with a tool, and never put a token that can send money in a chat.

The same idea applies to any bank. Prefer a connection that can only read, check that you can revoke it from the bank's side, and look at your connected accounts every few months to remove any you no longer use.

How DoorKeeping handles it

DoorKeeping reads your bank transactions through a read-only bank connection, matches deposits to the rent each tenant owes, and gives each LLC its own books. Rent and deposits stay in your own bank accounts, and DoorKeeping never holds your money: tenants pay your own bank account, by bank transfer or by Zelle where your bank supports it. DoorKeeping is $2 per unit per month with $0 in other fees.

Questions

Is Mercury a bank?

Mercury describes itself as a financial technology company, not a bank. Its banking services are provided through partner banks, so read the partner bank's role and the FDIC rules for how your balance is protected.

Can tenants pay a Mercury account by Zelle?

That depends on whether the account supports Zelle, which only participating banks and credit unions offer. Check Zelle's participant list and Mercury's help pages. If it is not supported, tenants can pay by bank transfer.

Do I need a separate Mercury account for each rental LLC?

A separate account for each LLC keeps each property's money and records apart, which supports the liability protection an LLC is meant to give. Ask your accountant how it applies to your structure.
