The software-as-a-service model (SaaS) allows software providers to offer fully integrated software applications to small and medium-sized businesses (SMB) at lower cost. Unlike SMBs, larger companies increasingly implement all-in-one integrated solutions that streamlines both, front-end and back-end operations and connect all information across an entire company. Why do SMBs hesitate? What can software providers do to encourage SMBs to opt for all-in-one SaaS solutions? Software solutions that have been designed for large or medium-sized companies clearly do not work for small companies including start-ups and "one person bands". Most business software out there looks daunting and SMBs, perhaps, only use 10% of the offered functionality. Owner managers and directors of SMBs are often overwhelmed by the complexity and customisability of existing software products that only applies to large organisations. Among the success factors for small business IT are simplicity, flexibility, and automatisation. SMB owners and managers should not need an IT or accounting degree to use their software. Do SaaS providers need to find a balance between black box (for simplicity) and full customisability (for flexibility) to tab the SMB market? A market that has neither standards nor market leaders.
