Online accounting software firm Xero is gearing up to launch its integrated payroll solution at 6:00am on Wednesday, March 23rd.

"We'll be offline for about 1 hour,” the company said in an update.

"Wages and salaries are the largest expense for many businesses, so sending detailed cost information from a pay run straight into the accounting ledger gives business owners a much better understanding of where the money is flowing. They can then prepare for the deduction of large expenses and the likes of superannuation payments.”

Check out a video of how the new system will work here.

And remember that one-hour downtime on Wednesday morning!
