Finly + Mercury
Payments · Two-way sync · Live since 2025 · About 6 minutes to connect
What it does
Finly reads the Mercury account and its cards as one feed, so a card charge and the statement line that clears it never arrive twice. Sub-accounts come across as they are set, which keeps a runway reserve out of the operating numbers.
What syncs
What moves, and which way.
Both directions, on every sync.Nothing here is a nightly batch —a record that changes at 14:02 is in the ledger before you look at it.
Mercury → Finly
- Account and sub-account balances
- Incoming and outgoing transfers, with references
- Card authorisations and their settlements
- Wire and ACH detail, including the counterparty
- Treasury movements, flagged as non-operating
- Statement lines, ready for matching
Finly → Mercury
- Ledger account codes, written back as metadata
- Reconciliation status on every statement line
- Entity tag, so a multi-entity group stays separate
Connected
What it looks like once it is on.
Every settlement, already split.
Gross, processing fees and refunds land as separate lines against the same Mercury settlement, each on its own account.The bank line that arrives two days later matches without anyone touching it.
Before you start
What you need, and what it will not do.
You need a Mercury account with owner or administrator access and a Finly plan that includes bank feeds, which means Core and above.One Mercury account maps to one Finly entity, so a group running several entities connects each one separately —that separation is also what keeps the fee accounts apart at the close.Nothing is installed, and the key never leaves Finly.
Two things it deliberately will not do.It will not move money:Finly reads Mercury and never initiates a payout, a refund or a transfer, so a bad sync cannot cost you anything.And it will not rewrite history —activity that settled before you connected stays exactly as it is unless you ask for the ninety-day backfill, which is a separate run and a reversible one.
