The integrated on-demand business management suite is now available in the UK, US, France, Germany, China, and India after several delays for fine-tuning.
SAP also announced the introduction of three new starter packages that provide a starting point for adoption of the complete Business ByDesign system.
SAP has been criticised for being too slow to bring its software-as-a-service offering to the market.
But, Tim Noble, managing director of SAP UK & Ireland, said the company believes it came to the marketplace early enough with SAP Business ByDesign.
"We have been working with pilot customers until now to ensure the solution is robust and ready for volume business," he said.
In May, Jim Hagermann Snabe, co-chief executive at SAP, said he had supported a delay in a full roll-out of Business ByDesign until now.
"I wanted Business ByDesign to be perfect from an infrastructure and delivery point of view before we rolled it out in volume," he said.
The new feature pack includes several innovations, such as real-time in-memory analytics, support for mobile devices, and a customisable user interface.
According to SAP, the feature pack provides the customer lifecycle management capabilities needed to support a large volume roll-out and reduce the cost of delivery.
Starter packages are predefined, focused subsets of the full SAP Business ByDesign suite that are deployed simply and are available at fixed implementation prices.
As business grows, users can expand the scope and turn on additional functionality that is already built in, said SAP.
