Understand negative balance line exports

Negative balance lines represent credits (or deductions) attached to a bill.

What changes in exports

Negative balance lines are exported as regular line rows with a negative signed unit/total value.
Sales summary still includes all bill lines in TotalNoTax and TotalTax.
Export summary now also includes a dedicated negative-balance breakdown:
- NegativeBalanceTotalNoTax
- NegativeBalanceTotalTax

Why values can be negative

Credits reduce bill totals.
Tax values for credit lines are also negative to preserve accounting consistency.

Validation rules

A negative balance line must use a positive quantity and a negative signed line amount.
Standard sale lines must keep non-negative signed amounts.
