Set the Expense Account field +2. Then add deductions + +### Problem: Wrong journal entry + +**Cause:** Using wrong account types + +**Solution:** +- Expense Account: Use expense account type +- Deductions: Use tax payable (current liability) accounts + +### Problem: Payment doesn't balance + +**Cause:** Deductions exceed payment amount + +**Solution:** +- Check Total Deductions +- Ensure it's less than Amount +- Adjust deduction amounts if needed + +## FAQ + +### Q: Why is Expense Account required? + +**A:** The Expense Account is required to ensure proper journal entry creation. It specifies which expense account should be debited for the full amount. + +### Q: Can I use Accounts Payable instead of Expense Account? + +**A:** No. When using deductions, you must use an Expense Account. This ensures the correct accounting treatment where: +- Expense is recorded at full amount +- Tax liabilities are created +- Bank is reduced by net amount + +### Q: What accounts can I use for deductions? + +**A:** Use tax payable accounts (Current Liability type) such as: +- PPh 21 (Income Tax Article 21) +- PPh 23 (Income Tax Article 23) +- PPh 29 (Income Tax Article 29) +- Other tax withholding accounts + +### Q: Can I have multiple deductions? + +**A:** Yes! You can add as many deduction lines as needed. Each deduction can have its own account and amount. + +### Q: What if I don't have deductions? + +**A:** If you don't have deductions, you don't need to set the Expense Account. You can use the standard payment flow with Accounts Payable. + +## Support + +For additional help: +1. Check the module documentation +2. Review example payments +3.
