Typically, implementing financial accounting without support and tools ends in failure and wasted time.
We rely on our practical experience in initial business model digitization, strategy development, service implementation, owner and manager training, video training for future employees, annual support, and annual service subscription.
The key result will be the implemented and functioning financial accounting, without which turnkey implementation will not be considered a result.
For financial accounting, any business is just numbers and it doesn't matter what the business does. Therefore, the complexity of the business model cannot be a reason to refuse financial accounting.
The only, but manageable, complexity will be building management policies or rules for data management and display for the manager or owner.
But this is a matter of one or two brainstorming sessions.
