Up to 40 development staff at Peace, formerly Peace Software, may leave the energy billing software provider following a review, chief executive Brian Peace says.
"There's no exact figure, but it may be up around 40 people."
Peace says those leaving will be split between the company's US and New Zealand operations.
However, the purpose of the review is to focus Peace away from development, towards product sales and therefore a significant number are likely to be leaving from Peace's Auckland development centre.
A statement from the company says 10-15% of the company's 400-odd staff may leave.
Brian Peace says the review has been prompted by a desire from its customers to deal with Peace for product sales and with systems integrators on development matters.
"That's something we believe the industry is driving at - moving from building, customising and implementing a product to providing a packaged product through partners."
Peace has partnerships with IBM and Accenture and Brian Peace says "utilities are looking at different ways of billing and are looking at outsourcing, with vendors as pure product companies".
The slowdown in the US economy has hit the energy sector less than some others but has still had an effect, he says and the high New Zealand dollar is also having some impact on Peace's returns.
Peace will be launching the newest version of its billing software, version 8, over the next few months.
