Implementing a cloud based system with Xero integration will combine your accounting solution to your online solution.  Combining all your pieces of software to one handy online system will help you improve how you run your business.  Generate invoices from your client orders or work requests, create purchase orders to replenish stock and sync information between the solutions with ease.  If required you may limit access to Xero and control the access in your cloud based system.

  One solution we have implemented is to  stage the information sent from your cloud based system to Xero.  Essentially this would then alleviate the problem if mistakes were made they could be rectified before sending anything to Xero.  
 

You can also configure any Xero settings in your cloud system so that most of the work is done before syncing data to Xero.
