OLSB customers have also complained that Office 365 is generally more expensive, and that having to hire a Microsoft partner to carry out the transition adds to the cost. OLSB is free, with optional fee-based add-ons. In comparison, the Office 365 plan for small businesses, called P1, costs US$6 per user, per month, and more if customers add the option of Office Professional Plus, an upgrade over the standard Office Web Apps.

While Office 365 is more feature-rich than OLSB, the question for OLSB customers is whether they will use the additional features they're paying more for.

"OLSB appealed to a lot of different people, especially because of the free website. Office 365 is targeted at meeting the needs of small business owners and professionals. Many OLSB customers won't see Office 365 as a good fit, especially since Office 365 isn't free," reads a on the official OLSB website.
