Wellington-based accounting software maker Xero has reached the milestone of more than one million subscribers worldwide.
Chief executive Rod Drury said the milestone coincided with the firm's 10th anniversary of being a listed company and will be celebrated with teams around the world.
"It's a massive achievement and it means a lot of risks have been taken out of our business," he said.
"It's nice to be able to celebrate both occasions at the same time."
Drury said he'd be celebrating with hot cross buns for staff.
