The program processes shareholding and director changes, produces resolutions, gives reminders of statutory deadlines, and securely stores the share register and other key company records.
The software is primarily targeted at accountants because, Bloy said, it would enable them to make their records legally compliant while avoiding costly consultations with lawyers.
"What we're seeing is that a lot of software companies trying to market time-saving software to lawyers who actually charge [for] their time. That's a tough sell.

Cunningham-Adams said people weren't hiring lawyers because of this cost, so accountants were doing this work themselves; sometimes incorrectly.

"The whole idea is to remove the dark art that the lawyer has, put it all down here with the people who are best placed to serve the business community of New Zealand, and get people compliant."
She said Kiwi accounting success story Xero had forged the path that CataLex hoped to follow.
"They're an informer as to what the accounting market's doing, but also just the world-wide market generally and they've shown the appetite for software to do things that have traditionally been done by people with a lot of education behind them."
CataLex has been working to integrate its software with the Companies Office so changes made on Good Company can be directly notified to the Companies Register. This will include filing annual returns.
CataLex has three other free pieces of software: Law Browser, which enables easier searching of legislation; Working Days, which calculates legal deadlines; and ConCat, which combines PDF documents.
