Migrate from Growth System to Odoo ERP

Growth System Customer records map to Odoo Contact with partner_type = 'contact' and customer_rank set to positive. The Growth System Customer name maps to Contact name; GSTIN maps to Odoo's dedicated l10n_in_gstin field (available on Contact via Indian localization). PAN and TAN store in custom fields if the customer requires them retained as structured data. Customer code from Growth System maps to Contact ref field for dedupe and external reference.

Growth System Vendor records map to Odoo Contact with partner_type = 'supplier' and supplier_rank set to positive. GSTIN maps to l10n_in_gstin; TDS section (e.g., 194C, 194J) from Growth System's statutory fields maps to Odoo's l10n_in_tds_section via a custom field or into the Fiscal Position mapping if TDS rates vary by vendor category. Vendor code maps to Contact ref.

Growth System stores GSTIN as a structured field on Customer and Vendor. In Odoo, GSTIN stores on the Contact record directly (l10n_in_gstin). We extract all GSTIN values from Growth System counterparties during the extraction phase, validate the GSTIN format (15-character alphanumeric), and write to the Contact field before any Sales or Purchase document is created. This ordering ensures GST calculation on invoices uses the correct state jurisdiction.

Growth System's TDS ledger data (TDS section, rates, threshold limits, certificate tracking) maps to Odoo's Fiscal Position rules under Accounting > Configuration > Fiscal Positions, combined with Withholding Tax configuration under Accounting > Configuration > Taxes. Each TDS section from Growth System (194C, 194H, 194J, 194Q, etc.) becomes a withholding tax rule in Odoo linked to the vendor Fiscal Position. We preserve the effective date and threshold amounts as Odoo tax rule conditions.

Growth System's chart of accounts maps to Odoo Account records. Indian-compliance accounts (CGST Input, SGST Input, IGST Input, CGST Output, SGST Output, IGST Output, TCS Payable, TDS Payable) map to Odoo's l10n_in tax accounts. Growth System cost-center assignments map to Odoo's analytic accounts if the customer uses the Analytic Accounting app. We create the CoA structure in Odoo before any transactional data to ensure all journal items post to valid accounts.

Growth System Items map to Odoo Product records. Growth System item type (goods, service, asset) maps to Odoo Product Type (storable product, consumable, service). HSN codes from Growth System map to Odoo's l10n_in_hsn_code field. GST tax category (exempt, 5%, 12%, 18%, 28%) maps to the product's invoice policy and the applicable Odoo tax. Product variants in Growth System map to Odoo Product Variants if the customer uses them.

Growth System Purchase Orders map to Odoo Purchase Orders; validated Purchase Invoices map to Odoo Vendor Bills (account.move with move_type = 'in_invoice'). Line-item tax amounts from Growth System recompute against the vendor's TDS rule and GSTIN-validated state code in Odoo before posting. The vendor contact's l10n_in_gstin field determines IGST vs. CGST+SGST splitting on the Odoo vendor bill.

Growth System Sales Orders map to Odoo Sale Orders; validated Sales Invoices map to Odoo Customer Invoices (account.move with move_type = 'out_invoice'). E-way bill references from Growth System store as custom fields on the Odoo account.move record. The customer contact's GSTIN validates for B2B vs. B2C invoicing rules in Odoo's Indian localization.

Growth System Employee records map to Odoo Employees (requires the HR app). Employee statutory data (PF registration, ESI registration, UAN, PAN) maps to Odoo's employee fields and contract configuration. If the customer licenses Odoo Payroll (Enterprise) or uses the community Indian Payroll module, we migrate salary structures, pay heads, and payslip history. PF/ESI employer and employee contribution rates migrate as salary rule configurations in Odoo Payroll.

Growth System stock transactions (grn, stock transfer, stock adjustment) map to Odoo Stock Moves and Quants. Growth System's warehouse assignment on line items maps to Odoo's Stock Location hierarchy (WH/Stock Location/Child Locations). Inventory valuation method (FIFO, weighted average) from Growth System maps to Odoo's product category valuation setting. We migrate open stock moves (not yet completed) as Odoo pickings in draft state for the warehouse team to process after cutover.

Growth System expense entries map to Odoo Expense records if the customer uses the Expense app, or to Vendor Bills if expenses are posted directly to the chart of accounts. TDS deduction on expense vouchers from Growth System maps to withholding tax configuration on the corresponding Odoo expense or vendor bill.

Growth System payment receipts and payments map to Odoo Account Payment records linked to the corresponding Customer Invoice or Vendor Bill. Payment mode (cash, bank, UPI, NEFT, RTGS) from Growth System maps to Odoo's journal on the Payment Method. Bank statement reconciliation from Growth System maps to Odoo Bank Statement Reconciliation or the Accounting > Customers > Payments interface.
