Execution Steps

1. Step 1

   Step 1: Opening balance on new supplier

   When a new supplier is created with initial balance, the system creates an opening_balance record in supplierBalance and sets supplier currentBalance.

2. Step 2

   Step 2: Purchases post payable movements

   Non-draft purchases create/update purchase ledger movements and increase supplier payable balance.

3. Step 3

   Step 3: Supplier payments reduce payable

   Supplier payment creates payment ledger movement and reduces supplier current balance. Editing payment adjusts by delta.

4. Step 4

   Step 4: Reversals and deletes

   Deleting purchase or payment triggers reversal logic to neutralize previous effect and keep balances consistent.
