What it does

Lateby is for Xero users who charge late payment interest. Choose your Xero invoice export, or the Aged Receivables Detail report saved to Excel, and Lateby works out simple interest on every late invoice, under the UK statutory rule (8% plus Bank Rate) or your own rate. It writes one draft interest invoice per customer as a Xero import file, with a PDF notice per customer showing each calculation. The file is read in your browser and is not uploaded.

Capabilities

Your Xero export in

The invoice export from Sales, Invoices, or the Aged Receivables Detail report saved to Excel. No file at hand? The page has a made-up sample to try.

UK statutory rate or your own

Under the UK rule each invoice gets 8% plus the Bank of England Bank Rate for its half-year, from a built-in table you can edit. Or enter your own yearly or monthly rate. Grace period, minimum charge, fixed sums and an "already billed up to" date.

Drafts and notices

A Xero import file with one draft interest invoice per customer, and a PDF notice per customer with each calculation. You import the drafts and approve them in Xero.

Files stay in your browser

The export is read in the page and is not uploaded. Lateby does not sign in to Xero. No sign-up is needed to try it.

Is Lateby independent?

Lateby is not affiliated with, endorsed by, or certified by Xero.

Limits and what we do not claim

  • Xero’s invoice export has no payment dates, so Lateby does not work out interest on invoices already paid late, and a part-paid invoice is charged on the amount still due today for the whole period.
  • Lateby does not connect to Xero and does not approve or send anything. You import the drafts and approve them in Xero.
  • Lateby is not affiliated with, endorsed by, or certified by Xero.
