Revolut Business,
accounting-ready.

Bookrail is accounting software for Revolut Business. It connects read-only to a company’s account and turns it into a correct, auditable double-entry ledger: numbers that reconcile, receipts that are never missing, and tax-ready summaries your accountant can trust.

Raw Revolut Business data goes in; a reconciled double-entry ledger comes out.

THE PROBLEM

Flat statements
lie.

Revolut Business is excellent at banking and hard on bookkeeping. Exported flat into a spreadsheet or a generic accounting tool, its data misleads in four reliable ways.

  • Transfers that are not income

    A movement between two pockets of the same company looks like an external transfer on a flat statement. Counted once as income and once as expense, it inflates both sides of the books.

  • FX legs that lose their rate

    An exchange is two movements in two currencies. Exported flat, the legs disconnect and the applied rate disappears, so the balances stop adding up.

  • Fees detached from their cause

    Fees arrive as separate line items with no link to the transaction that caused them, so someone guesses them into place by hand.

  • Receipts in another module

    Expenses and their receipts live in the Revolut Business Expenses module, disconnected from the statement your accountant receives. Missing documentation surfaces at inspection time, which is the worst time.

WHAT BOOKRAIL DOES

Books that
reconcile.

  • A ledger, not a statement

    Every movement becomes a double-entry journal entry on the Spanish chart of accounts. The ledger is append-only: corrections are reversal entries, so the audit trail is complete by construction.

  • Internal transfers, deduplicated

    Bookrail knows every account and pocket the company owns, so a pocket-to-pocket movement becomes one neutral entry. Never income, never expense, never counted twice.

  • FX at the applied rate

    Exchanges post with the rate Revolut Business actually applied, and realized differences land where Spanish accounting expects them. Balances agree because the numbers come from Revolut Business itself.

  • Reconciliation as a guarantee

    Every day, per sub-account: the ledger balance must equal the Revolut Business balance, or an alert fires with a diff view. Green means the books are right, not probably right.

  • Every receipt, filed

    Expenses are matched to their transactions and receipts are archived immutably. A missing receipt shows up in a weekly digest, not in an inspection.

  • Balances at any date

    The exact position of every account and currency at the close of any past day, something Revolut Business itself cannot answer historically. Quarter closes stop being archaeology.

RUNNING ON OUR OWN BOOKS

runs on Revolut Business

We built Bookrail because our own accountant could not trust our Revolut Business exports. It has been running on Spainlink’s real books since May 2024: every sub-account and every currency, reconciled daily against the balances Revolut Business reports, to the cent.

What it deliberately does not do

  • It is read-only by design. Bookrail can see the account; it can never move money.
  • It drafts tax summaries and exports; it never files anything. Filing stays with you or your accountant.
  • It does not issue invoices, which keeps it outside Spain’s certified invoicing software regime.
  • The ledger is append-only. Corrections are new entries, never edits.

Built for us. Opening up.

Bookrail runs Spainlink’s own books today. We are opening it to a small number of companies that live on Revolut Business, and to the accountants who deal with their statements. Tell us about your setup and we will tell you honestly whether it is ready for you.
