Your entire loan book,
managed and posted to Xero automatically.

Loanbooq connects directly to Xero, calculates interest for every loan in your portfolio, generates amortisation schedules, posts the journal entries for you, or posts them itself every month, and gives you a full audit trail, all in one place.

Loanbooq's Post page: six loans checked up to 31 August 2026, each showing the interest to post, the balance after and a Ready status, with a button to post all six to Xero

Built for accounting firms, licensed FSPs, family offices, private lenders and treasury teams that run their books in Xero.

From spreadsheet to posted journals.

Manual loan book management is slow,
error-prone, and completely unscalable.

Most firms are still tracking loans in spreadsheets and manually entering journals into Xero every month. There's a better way.

Without Loanbooq

  • Calculate interest manually in Excel for every loan, every month
  • Re-enter figures into Xero by hand, one journal at a time
  • No audit trail, so no way of knowing who posted what and when
  • Reference-rate loans need constant rate lookups and manual recalculations

With Loanbooq

  • Connect to Xero once. Opening balances and transaction history are pulled automatically
  • Post every loan to Xero in one click, or switch on automatic posting and each month's interest is posted on the day you choose
  • Every post logged with a full audit trail, and a notification of what was posted and what needs a look
  • Prime changes flagged the day the Reserve Bank publishes them, and applied in one click

See what it does, how it works,
and what it costs.
