K. Strachan updated the QuickBooks Online integration documentation in the codatio/codat-docs repository to clarify a platform limitation affecting default account mappings for shipping and gratuity lines when pulling invoices. Using Markdown and a focus on precise documentation, K. Strachan added a targeted note that explains how changes to default accounts in QuickBooks Online can lead to incorrect mappings within Codat. This work addressed a specific gap in developer knowledge, reducing the risk of mis-mappings and lowering potential support overhead. The update improved the onboarding experience for developers by providing clear, up-to-date reference material, though no code-level bugs were addressed.
