The change also improves reliability when multiple devices or offline orders are involved by marking offline-generated numbers distinctly and reducing numbering conflicts.

Point of Sale screens now better support offline use for customer selection, payment, ticket handling, and related order workflows. This helps store teams keep serving customers more reliably when connectivity is limited or interrupted.

GSTR-1 reports now warn users when credit notes do not have a linked main invoice. The alert helps users quickly find and update those credit notes, improving the accuracy of Indian tax reporting.

In the CDNUR section of the GSTR-1 reports, the main invoice amount of credit notes is checked for reporting. However, there are instances where credit notes exist without corresponding main invoices.

With this PR, an alert will be displayed above the report if any credit notes are found without main invoices. This alert will include an action that redirects the user to the list view of these credit notes. From there, the user can select the main invoice for each credit note.
