Overview

What this migration involves

Moving from WP ERP to Odoo ERP is a cross-platform migration that must extract data from WordPress custom tables (erp_hr_*, erp_crm_*, erp_ac_*) because WP ERP stores its core records outside standard WordPress posts and user meta. We perform direct MySQL extraction, cross-reference WordPress user IDs for HR employee linkage, resolve WooCommerce CRM integration duplicate contacts, and map the WP ERP Chart of Accounts to Odoo's COA structure before import. Odoo runs on its own application server separate from WordPress, which resolves the PHP memory limits and database bottlenecks that WP ERP users report at scale. Workflow rules stored as serialized PHP in wp_options do not migrate as code; we deliver a written inventory of every active workflow for the customer's admin to rebuild in Odoo Studio or through Python-based server actions. The migration runs through Odoo's XML-RPC API with rate-limit handling and batch chunking, targeting the correct Odoo model (hr.employee, res.partner, crm.lead, account.move) in dependency order.

Why teams make this switch

Two sides of the same decision

Leaving

WP ERP logo

WP ERP

What's pushing teams away

  • Extension costs stack up quickly — Recruitment, Payroll, Deals, Workflow, and others are billed per-month on top of the core module, making the total cost of ownership unpredictable.
  • The CRM module is functionally basic compared to dedicated platforms — no advanced automation, limited pipeline customization, and a shallow integrations marketplace beyond WooCommerce.
  • Plugin conflicts with other WordPress plugins cause data inconsistency or crashes, and support response times frustrate users managing business-critical operations.
  • WordPress as the application layer limits scalability and performance — growing teams hit PHP memory limits and database bottlenecks that standalone ERP systems do not share.
  • Limited API documentation makes third-party integrations and custom development difficult, pushing technically ambitious teams toward platforms with better developer ecosystems.

Choosing

Odoo ERP logo

Odoo ERP

What's pulling them in

  • Modular pay-as-you-grow model with 80+ apps under one database — teams start with CRM and add Accounting, Inventory, or Manufacturing without switching platforms.
  • Free Community edition lets businesses validate Odoo fit before committing to Enterprise licensing costs that scale with user count.
  • Lowest per-user pricing among mid-market ERPs, with a published free tier for one app and Standard plans starting around $24.90 per user per month.
  • Native integration between modules — a confirmed Sales Order automatically updates inventory, invoicing, and accounting without manual re-entry.
  • Strong Odoo Gold Partner ecosystem provides local implementation support, reducing risk for companies without in-house developers.

Object mapping

How WP ERP objects map to Odoo ERP

Each row shows how a WP ERP object lands in Odoo ERP, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

WP ERP

erp_hr_employees

maps to

Odoo ERP

hr.employee

1:1
Fully supported

WP ERP employee records in erp_hr_employees map to Odoo hr.employee. We resolve the wp_user_id foreign key to pull the WordPress user display name, email, and role, then create the hr.employee record with name, work email, department_id (mapped from erp_hr_departments), job_title, hire_date, and employment status (employment_status field). Compensation data from the HRM module (salary, pay frequency) maps to hr.contract records linked to the employee. Department tree is migrated first so that employee.department_id references are satisfied during employee import.

WP ERP

erp_hr_departments

maps to

Odoo ERP

hr.department

1:1
Fully supported

WP ERP department records in erp_hr_departments use a simple parent_id hierarchy. We migrate the department tree top-down, preserving the parent-child structure in Odoo's hr.department model where each department has a manager_id (resolved from the migrated hr.employee record) and a parent_id pointing to the parent department. Departments must migrate before employees so that department_id foreign keys are valid at employee insert time.

WP ERP

erp_crm_contacts

maps to

Odoo ERP

res.partner

1:many
Fully supported

WP ERP CRM contacts map to Odoo res.partner. WP ERP stores individuals (contacts) and organizations (companies) as separate tables (erp_crm_contacts and erp_crm_companies), while Odoo uses a single res.partner model with an is_company toggle. We map WP ERP contacts where is_crm_company=0 to res.partner with is_company=False, and WP ERP companies to res.partner with is_company=True. The lifecycle_stage and source attribution from WP ERP migrate as custom Char fields on res.partner. When WooCommerce CRM integration is active, we detect duplicate contact candidates (same email in both manual CRM contacts and WooCommerce order records) and give the customer the choice to merge before export.

WP ERP

erp_crm_companies

maps to

Odoo ERP

res.partner (is_company=True)

1:1
Fully supported

WP ERP company records map to Odoo res.partner with is_company=True. The company name, billing address, phone, website (domain field), and industry classification migrate directly. Company-to-contact relationships stored in erp_crm_contact_relations are preserved as child res.partner records linked to the parent company partner. Company IDs are remapped during migration to match Odoo's sequential partner ID generation, and the mapping table is maintained so that any deal associations reference the correct partner.

WP ERP

erp_crm_deals (Deals extension)

maps to

Odoo ERP

crm.lead

1:1
Fully supported

WP ERP Deals ($9.49/mo extension) map to Odoo crm.lead. Deal title, value, currency, stage, owner (hubspot_owner_id resolved to Odoo res_users), and pipeline association migrate to crm.lead fields (name, planned_revenue, currency_id, stage_id, user_id, team_id). WP ERP pipeline stages are mapped to Odoo stage names within the crm.lead stage pipeline configuration. The deal_currency field from WP ERP maps to Odoo's currency_id using ISO 4217 currency codes. Deals without a linked contact or company are migrated as unassigned leads for the customer admin to route.

WP ERP

erp_crm_activities

maps to

Odoo ERP

mail.message + mail.activity

1:1
Fully supported

WP ERP CRM activities (calls, meetings, emails, tasks, notes) stored in erp_crm_activities with polymorphic type fields map to Odoo mail.message records linked to the parent res.partner or crm.lead. Each activity type maps to a different Odoo model: calls and tasks become mail.message with subtype indicating call or task; emails become mail.message with email=True; meetings create calendar.event records linked via mail.message. Notes migrate as mail.message with note=True. We preserve the original activity timestamp and the owner (resolved via wp_user_id to Odoo res_users) for audit continuity.

WP ERP

erp_ac_chart_of_accounts

maps to

Odoo ERP

account.account

lossy
Fully supported

WP ERP Chart of Accounts in erp_ac_chart_of_accounts maps to Odoo account.account records. The primary challenge is translating WP ERP's flat COA with type and subtype fields into Odoo's structured account type hierarchy (view, receivable, payable, liquidity, revenue, expense, etc.). We map WP ERP account types (Asset, Liability, Equity, Income, Expense) to Odoo account.account.account_type values, and preserve the parent-child account grouping in Odoo's account.group model for financial statement structuring. Account codes are mapped directly; the customer configures Odoo's account_digits setting to match WP ERP's code length before import.

WP ERP

erp_ac_customers

maps to

Odoo ERP

res.partner (customer=True)

1:1
Fully supported

WP ERP accounting customers in erp_ac_customers link to CRM contacts via erp_crm_contacts.id. We resolve this cross-reference during migration so that the accounting customer lands as the same res.partner record as the CRM contact, with customer_rank elevated and the account_receivable account assigned from the mapped COA. Any open receivable balance from WP ERP's accounting ledger migrates as a start_balance on the res.partner record.

WP ERP

erp_ac_vendors

maps to

Odoo ERP

res.partner (supplier=True)

1:1
Fully supported

WP ERP vendor records in erp_ac_vendors map to Odoo res.partner with supplier=True. We migrate the vendor name, billing address, contact email, and phone. Vendor-ledger entries in the accounting module link via the vendor_id foreign key to the partner record. The account_payable account from the mapped COA is assigned to the vendor partner record in Odoo.

WP ERP

erp_ac_invoices

maps to

Odoo ERP

account.move

1:1
Fully supported

WP ERP invoices in erp_ac_invoices map to Odoo account.move records with move_type set to out_invoice (customer) or in_invoice (vendor). We extract line items, tax codes (mapped to Odoo account.tax records using the tax name as the dedupe key), payment status, and due date. WP ERP invoice status (open, paid, voided) maps to Odoo's state field (draft, posted, cancel). Open invoices migrate as posted journal items against the correct receivable or payable account. Closed invoices migrate with state=posted and the payment reconciliation recorded against the bank journal. We flag any partially paid invoices for manual reconciliation in Odoo after import.

WP ERP

erp_ac_journal_entries

maps to

Odoo ERP

account.move (entry)

1:1
Fully supported

WP ERP journal entries in erp_ac_journal_entries (both manual entries and those generated by the Payroll module) map to Odoo account.move records with move_type=entry. Each journal entry's debit and credit line items are mapped to Odoo account.move.line records with the correct account_id resolved from the COA mapping, partner_id for receivable/payable lines, and analytic_account_id if analytic dimensions exist in the WP ERP entry. Payroll-generated journal entries are imported as entry moves with a payroll reference in the narration field for audit trail purposes.

WP ERP

erp_hr_payroll_historical (Payroll extension)

maps to

Odoo ERP

hr.payslip

1:1
Fully supported

WP ERP Payroll extension ($9.49/mo) historical payslip records in erp_hr_payroll* tables map to Odoo hr.payslip records linked to the corresponding hr.employee. We extract payslip date, worked days, inputs (allowances, deductions), and the computed net pay. Payslip PDFs are not regenerated by Odoo; if the customer requires payslip documents for compliance, they must either regenerate them in Odoo using the payslip data or retain the original WP ERP PDFs as an archive. We document this as a post-migration action item.

Pair-specific challenges

  • WP ERP custom tables require direct MySQL extraction

    WP ERP stores its core data in custom WordPress tables (erp_hr_*, erp_crm_*, erp_ac_*) rather than standard WordPress posts or user meta. Neither the WordPress XML export nor WP-CLI exports capture these tables. We perform direct MySQL extraction from each custom table, cross-referencing wp_users and wp_usermeta for HR employee assignments. Failing to do a direct database pull means HR employee records, all accounting data, and CRM deal associations silently drop from the export. This is a known limitation of WP ERP's architecture that affects every migration off the platform.

  • Chart of Accounts structure does not map automatically

    WP ERP's chart of accounts uses a flat table with type/subtype labels; Odoo uses a nested account.group model with account_type enums that determine financial statement placement. A WP ERP account marked as an Expense type in Odoo must be assigned the correct account_type (expense, expense_depreciation, expense_direct_cost) to appear in the right P&L section. We flag every account that cannot be auto-mapped from the WP ERP subtype field and escalate to the customer for manual COA review before the Odoo import begins. Mis-mapped accounts produce incorrect financial statements that are expensive to correct after go-live.

  • WooCommerce CRM duplicates inflate contact record count

    When the WooCommerce CRM integration is active, WP ERP creates a CRM contact record for every WooCommerce order customer. If the same email address appears in both a manually created CRM contact and a WooCommerce order, WP ERP creates two separate contact records. We detect these duplicate candidates during the migration scope phase using email deduplication across erp_crm_contacts and the WooCommerce order customer table. The customer chooses whether to merge duplicates before export. Without this step, Odoo imports both records and the duplicate must be merged manually in Odoo after migration, which is more error-prone than doing it at the source.

  • Workflow automation rules are serialized PHP in wp_options

    WP ERP's Workflow extension stores automation rules as serialized PHP arrays in the WordPress wp_options table under option_name LIKE '%erp_workflow%'. These cannot be imported into Odoo, which uses Python-based server actions and Odoo Studio for workflow automation. We extract the rule structure (trigger module, conditions, action set) and document it in a migration summary with a recommended Odoo equivalent (domain-based automatic actions, computed fields, or Python server actions). The customer's Odoo admin rebuilds equivalent rules post-migration. This applies to every customer who used the Workflow extension, regardless of the destination ERP.

  • Odoo does not validate imported data — bad data enters silently

    Unlike some ERP platforms that enforce data quality at import, Odoo accepts whatever data is provided through its XML-RPC API unless validation rules are explicitly configured. WP ERP datasets with duplicate vendor listings, contacts missing email addresses, products with out-of-date SKUs, or open invoice balances from years prior will all import into Odoo without correction. We run a pre-migration data quality audit against the WP ERP dataset and produce a deduplication and cleanup report before the Odoo import. The customer is responsible for acting on that report; we proceed with migration only after the customer signs off on the data quality state.

Migration approach

Six steps for a successful WP ERP to Odoo ERP data migration

  1. Discovery and scope definition

    We audit the source WP ERP installation across all active modules (HRM, CRM, Accounting, and any paid extensions: Deals, Payroll, Document Manager, Inventory, Workflow). We count record volumes per table (erp_hr_employees, erp_crm_contacts, erp_crm_companies, erp_ac_chart_of_accounts, erp_ac_invoices, erp_ac_journal_entries), identify any WooCommerce CRM integration tables, and flag the payroll extension presence. We pair this with an Odoo edition recommendation: Odoo Community (free, self-hosted) covers most migrations; Odoo Enterprise is recommended if the customer needs the Studio builder, automated actions, or Odoo.sh hosted deployment with built-in CI/CD. The discovery output is a written migration scope and data volume summary.

  2. Source data extraction from MySQL

    We connect directly to the WP ERP MySQL database and extract each relevant table using SELECT queries ordered by foreign key dependencies. We extract Departments first (no dependencies), then Employees (with wp_user cross-reference), then CRM Contacts and Companies (with deduplication against WooCommerce customer records), then Deals, then Activities. The accounting extraction runs in parallel and includes Chart of Accounts, Customers, Vendors, Invoices, and Journal Entries. Each extraction produces a CSV with header row mapping to the Odoo XML-RPC field names. We flag any records with missing required foreign keys and surface them in a pre-migration data quality report.

  3. Odoo schema provisioning and COA design

    Before any data import, we configure the destination Odoo database. This includes activating the required apps (HR, CRM, Accounting, Inventory as needed), creating the COA structure by mapping WP ERP account records to Odoo account.account entries with correct account_type values, configuring taxes (mapping WP ERP tax codes to Odoo account.tax records using name and amount as the dedupe key), setting up Odoo chart of accounts digits to match WP ERP account code length, and creating any required Odoo journal records (sale journal, purchase journal, general journal) that invoice and journal entry imports target. We deploy this configuration into a test database first.

  4. Sandbox migration and data reconciliation

    We run a full migration into an Odoo test database (a clean Odoo install or a restored backup) using the extracted CSV data. We validate record counts per object, spot-check 20-30 records against the WP ERP source for field-level accuracy, confirm that partner records are correctly linked to accounting accounts, and verify that journal entries balance (debits equal credits for each entry). The customer reviews the sandbox and approves the mapping before production migration begins. Any COA corrections, duplicate merge decisions, or account type adjustments happen here.

  5. Production migration in dependency order

    We run production migration in strict record-dependency order: Departments (no dependencies), Employees (with wp_user resolution), Companies/Partners, Customers, Vendors, Products (if inventory is in scope), Chart of Accounts, Invoices, Journal Entries, Deals/Leads, Activities. Each phase emits a reconciliation report (record count in, record count created, record count failed). Partner reconciliation links accounting customers and vendors to the same res.partner record that CRM contacts created, preventing duplicate partner records. We use Odoo's XML-RPC API with batch writes of 100 records per request and exponential backoff on rate-limit responses.

  6. Cutover, validation, and workflow handoff

    We freeze WP ERP writes during the cutover window, run a final delta migration of any records modified since the initial extraction, verify invoice and journal entry totals match WP ERP's accounting trial balance, then set Odoo as the system of record. We deliver the workflow inventory document to the customer's Odoo admin. We support a three-day hypercare window to resolve any post-import reconciliation issues. We do not rebuild WP ERP Workflow extension rules as Odoo automated actions inside the migration scope; that is a separate engagement requiring a business requirements workshop to map trigger-action logic to Odoo's Python-based automation model.

Platform deep dives

Context on both ends of the pair

WP ERP logo

WP ERP

Source

Strengths

  • Free core plugin provides functional HRM and CRM without any purchase, making pilot migrations low-cost.
  • Deep WooCommerce integration syncs order history, customer LTV, and product data directly into CRM contacts.
  • Extension marketplace of 23+ add-ons covers specific verticals like Recruitment, Payroll, and Asset Management for businesses with targeted needs.
  • Runs entirely inside WordPress admin — no separate application to log into for teams already managing their site via WordPress.
  • Open-source core available on GitHub allows self-hosted deployments and code-level customization.

Weaknesses

  • WordPress as the underlying application layer constrains performance, security, and scalability compared to standalone ERP platforms.
  • CRM features are intentionally narrow — limited pipeline stages, basic activity logging, and no native marketing automation.
  • API lacks public documentation and a developer SDK, making automated integrations and migrations harder to architect.
  • Extension-based pricing model means the advertised starting price of $12.99/user/month does not reflect the full cost of Payroll, Recruitment, or Workflow modules.
  • Plugin architecture creates cross-dependency risks — deactivating one extension can break data relationships in others.

Odoo ERP

Destination

Strengths

  • Modular architecture with 80+ apps sharing one database — add Sales, Accounting, Inventory, and Manufacturing incrementally.
  • Free Community edition for self-hosting with no per-user license cost, backed by an active open-source community.
  • Per-user pricing starting around $24.90/month on Standard, significantly lower than comparable ERPs like NetSuite or SAP.
  • Automatic workflow propagation across modules — a confirmed sales order updates inventory, triggers invoicing, and posts accounting entries without manual steps.
  • Odoo.sh provides a managed cloud hosting environment with CI/CD for custom module deployment and staging databases.

Weaknesses

  • Performance suffers under heavy customization — large implementations with many active modules require dedicated optimization.
  • No single-click migration between Odoo major versions; each release introduces ORM changes, deprecated API calls, and schema revisions requiring manual adaptation.
  • Per-user and per-module licensing costs can escalate unpredictably for growing teams adding multiple apps.
  • Steep learning curve with hundreds of configuration options across dozens of modules creates adoption friction and training requirements.
  • Support tiers on Enterprise have inconsistent response times, pushing some customers toward alternatives with more reliable SLAs.

Most migrations land between two and four weeks for accounts with no paid accounting extensions, up to 2,000 employees, 5,000 contacts, and under 500 open invoices. Migrations that include the full accounting module (COA remapping, open invoice migration, multi-year journal entry history) plus payroll historical records move to six to ten weeks because of COA structure translation, Odoo chart of accounts configuration, and accounting ledger reconciliation. Odoo implementation timelines from external sources (Techvoot, Waogroup, Ahex Technologies) confirm that 3-5 module deployments typically run 8-12 weeks; WP ERP migration time is a subset of that since we handle only data migration, not Odoo configuration itself.
