OSLO, Sept 10 (Reuters) - Norwegian software services provider Visma said on Friday it could carry out an initial public offering in 2023 to list its shares on Euronext's Oslo stock exchange.

Visma, majority owned by private equity firm Hg, said late on Thursday that a group of institutional investors had bought stakes in the firm, valuing it at 165 billion Norwegian crowns ($19 billion).

"We are considering an IPO during 2023, of course given that market conditions are favourable. The Oslo Stock Exchange could be a good option," a company spokesperson said in an emailed statement.

Visma provides business software such as accounting packages across much of Europe, delivered through cloud computing, and has seen 20 years of uninterrupted revenue growth.

"The future looks bright for the growth of digital services, as businesses increasingly see the value of cloud solutions to handle their most important business processes," Visma's Chief Executive Merete Hverven said in a statement.

Visma said on Thursday that Aeternum Capital, the Government Pension Fund Norway (Folketrygdfondet) and Vind had each taken stakes of between 0.4% and 0.6% in a sale of existing shares, joining a list of owners that also includes Warburg Pincus and Singapore's GIC.

ABG Sundal Collier and Goldman Sachs International acted as joint placement agents in the share transaction.
