This article provides a comprehensive, step-by-step walkthrough for implementing Odoo Financials and CRM.  There will be 5 articles as lot of details to cover.

Step 4: Tax Configuration

Taxes in Odoo are highly flexible but also one of the most commonly misconfigured areas, especially for businesses operating in multiple jurisdictions.

What to Do

• Navigate to Accounting > Configuration > Taxes.
• Review taxes installed by the fiscal localization package.
• Create or adjust taxes: define tax rate, tax type (sale/purchase), tax account (for tax collected/paid), and tax group.
• Configure tax rounding: per line vs. globally (critical for invoice totals matching paper returns).
• Set default taxes on product categories and individual products.
• Configure fiscal positions to map taxes for specific customer/supplier groups (e.g., EU VAT reverse charge, zero-rated exports).
• Set up tax reports and check mapping to your jurisdiction’s tax return format.

Key Issues to Consider

• Tax rounding method must match your jurisdiction’s requirement. UK and EU usually require line-level rounding; some jurisdictions require global rounding. Mismatches cause penny differences on returns.
• Fiscal positions are commonly overlooked. Without them, VAT will be incorrectly applied to EU B2B transactions, exports, and exempt supplies.
• Always test tax calculations with sample invoices and compare to manual calculations before go-live.
• If you are subject to Making Tax Digital (MTD) in the UK or similar digital reporting mandates, verify the tax report integration is correctly configured before the first reporting period.

Step 5: Banking and Payment Setup

Connecting Odoo to your bank accounts enables bank reconciliation, which is the process of matching bank statement lines to accounting entries — a daily or weekly task for any finance team.

What to Do

• Go to Accounting > Configuration > Journals and create Bank journals for each bank account.
• Enter IBAN/account number, bank name, and currency for each bank journal.
• Set up bank feeds: connect via Odoo Bank Synchronization (Plaid/Salt Edge integration on Odoo Online) or import OFX/CSV/CAMT bank statements manually.
• Configure payment methods: define inbound (customer payments) and outbound (supplier payments) methods per journal.
• Set up payment terms (e.g., Net 30, 2/10 Net 30, COD) in Accounting > Configuration > Payment Terms.
• Configure cash journals if your business handles petty cash.

Key Issues to Consider

• Bank synchronization availability varies by country and bank. For UK banks, connectivity via Open Banking APIs may require separate setup and FCA-authorised provider agreements.
• Payment terms directly affect cash flow reporting and aged debtor/creditor reports. Define them precisely and map them correctly to customer/supplier records.
• Outstanding payments account and outstanding receipts account must be configured per journal. These are the transit accounts used between payment registration and bank reconciliation.
• BACS, SEPA, or other batch payment file formats require additional configuration in the payment acquirer/provider settings and may require Odoo Enterprise.

Step 6: Customer and Supplier Master Data

Clean, accurate partner (customer and supplier) master data is essential for accurate receivables management, purchasing, and CRM.

What to Do

• Import or create customers and suppliers via Contacts module.
• Classify contacts: set ‘Customer Rank’ and/or ‘Supplier Rank’ so they appear in the correct views.
• Set default payment terms, payment method, and fiscal position per customer/supplier.
• Assign account receivable/payable accounts per partner if they differ from the default (useful for inter-company accounts).
• Define customer credit limits (requires the Credit Limit module or customization in standard Odoo).
• Tag and categorize customers for CRM segmentation purposes.

Key Issues to Consider

• Duplicate contacts are the most common data quality issue. Run deduplication before import and enforce a naming convention (company name format, abbreviations).
• Ensure VAT numbers are entered correctly for B2B customers in EU/UK. Odoo can validate VIES VAT numbers automatically — enable this in settings.
• Assign the correct country and state to each contact. This drives fiscal position and tax application automatically.
• Opening balances for receivables/payables must be entered as journal entries or opening invoices as at the go-live date.
