Finly + Fortnox

What it does
Finly books card spend and invoices into Fortnox daily rather than at month end, and keeps the verification series unbroken. Cost centres and projects come with the row, so the accountant opens a finished ledger instead of a shoebox.
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.
Fortnox → Finly
- The BAS account plan and its active accounts
- VAT codes and their Skatteverket boxes
- Cost centres and projects
- Suppliers and their bankgiro details
- Bank accounts and their ledger mapping
- The locked bookkeeping date
Finly → Fortnox
- Card spend as vouchers in their own series
- Supplier invoices with the PDF attached
- Reimbursements as one voucher per pay run

What it looks like once it is on.
Every line, already coded.
Card spend, bills and reimbursements arrive in Fortnox with the account, the tax treatment and the cost centre already on them.The bank feed matches them without anyone opening a spreadsheet.
Before you start
What you need, and what it will not do.
You need a Fortnox account with adviser or administrator rights and a Finly plan that includes the ledger sync, which means Core and above.One Fortnox organisation maps to one Finly entity, so a group running several sets of books connects each one separately —that separation is what keeps the intercompany lines apart at the close.Nothing is installed, and the credentials never leave Finly.
Two things it deliberately will not do.It will not post into a locked period:if the month is closed in Fortnox, the entry waits in Finly until you reopen it or roll it forward.It will not touch master data —Finly reads your chart, your dimensions and your suppliers and never writes them back, so a mapping change is always yours to make.
