Odoo Accounting Setup

Example 1: Create a Payment Term (Net 30 with 2% Early Pay Discount)

Menu: Accounting → Configuration → Payment Terms → New

Name: Net 30 / 2% Early Pay Discount
Company: [Your Company]

Lines:
  Line 1:
    - Due Type: Percent
    - Value: 100%
    - Due: 30 days (full balance due in 30 days)

Early Payment Discount (Odoo 16+):
  Discount %: 2
  Discount Days: 10
  Balance Sheet Accounts:
    - Gain: 4900 Early Payment Discounts Granted
    - Loss: 5900 Early Payment Discounts Received

Note (v16+): Use the built-in Early Payment Discount field instead of the old split-line workaround. Odoo now posts the discount automatically when the customer pays within the discount window and generates correct accounting entries.

Example 2: Fiscal Position for EU VAT (B2B Intra-Community)

Menu: Accounting → Configuration → Fiscal Positions → New

Name: EU Intra-Community B2B
Auto-detection: ON
  - Country Group: Europe
  - VAT Required: YES (customer must have EU VAT number)

Tax Mapping:
  Tax on Sales (21% VAT) → 0% Intra-Community VAT
  Tax on Purchases      → 0% Reverse Charge

Account Mapping:
  (Leave empty unless your localization requires account remapping)

Example 3: Reconciliation Model for Bank Fees

Menu: Accounting → Configuration → Reconciliation Models → New

Name: Bank Fee Auto-Match
Type: Write-off
Matching Order: 1

Conditions:
  - Label Contains: "BANK FEE" OR "SERVICE CHARGE"
  - Amount Type: Amount is lower than: $50.00

Action:
  - Account: 6200 Bank Charges
  - Tax: None
  - Analytic: Administrative

Best Practices

• ✅ Do: Install your country's localization module first (l10n_us, l10n_mx, etc.) before manually creating accounts — it sets up the correct chart of accounts.
• ✅ Do: Use Fiscal Positions to automate B2B vs B2C tax switching — never change taxes manually on individual invoices.
• ✅ Do: Lock accounting periods (Accounting → Actions → Lock Dates) after month-end closing to prevent retroactive edits.
• ✅ Do: Use the Early Payment Discount feature (v16+) instead of splitting payment term lines for discount modelling.
• ❌ Don't: Delete journal entries — always reverse them with a credit note or the built-in reversal function.
• ❌ Don't: Mix personal and business transactions in the same journal.
• ❌ Don't: Create manual journal entries to fix bank reconciliation mismatches — use the reconciliation model workflow instead.

Limitations

• Does not cover multi-currency revaluation or foreign exchange gain/loss accounting in depth.
• Country-specific e-invoicing (CFDI, FatturaPA, SAF-T) requires additional localization modules — use @odoo-l10n-compliance for those.
• Payroll accounting integration (salary journals, deduction accounts) is not covered here — use @odoo-hr-payroll-setup.
• Odoo Community Edition does not include the full lock dates feature; some controls are Enterprise-only.
