Overview
Fergus is a field-service management platform built around Jobs, Clients, Quotes, and Pricing Tiers — its data model assumes every customer interaction terminates in a billable work order. Odoo CRM models the same relationship through res.partner (contacts/companies), crm.lead (leads and opportunities), and sale.order (quotations that become confirmed sales). The migration must bridge these two architectures: Fergus's job-centric record graph has to be flattened into Odoo's opportunity-with-lines model, and Fergus's client-level pricing tiers need to become either Odoo pricelist rules or custom fields on the partner record. We export Fergus data via its REST API (100 req/min rate limit) in ordered batches — Clients first, then Contacts, then Quotes and Jobs — before loading into Odoo's xmlrpc/JSON-RPC API. Custom fields and pricing tier logic that cannot map directly are preserved as Odoo custom fields (x_ prefix) with transformation notes for your admin to implement as Pricelists or product variants post-migration. FlitStack sequences the load so foreign keys resolve correctly: partner records exist before quotes, and quote records exist before job-linked sale orders. A delta-pickup window captures any in-flight quotes or job updates during cutover. Workflows, automations, and payment integration settings do not migrate — they must be rebuilt in Odoo's Studio or through custom modules.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Fergus object lands in Odoo CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Fergus
Client
Odoo CRM
res.partner
1:1Fergus Client maps directly to Odoo res.partner. Odoo stores the client type (company vs individual) in the is_company boolean and the contact type in partner properties. Client-level pricing tiers from Fergus become Odoo Pricelist rules linked to the partner record post-migration.
Fergus
Contact
Odoo CRM
res.partner (contact)
1:1Fergus Contact maps to res.partner records of type 'contact' linked to the parent client partner via the parent_id field. Fergus contact mobile and phone fields map to Odoo's phone and mobile fields. Email addresses map directly to the email field on the partner record.
Fergus
Quote / Estimate
Odoo CRM
sale.order
1:1Fergus Quotes map to Odoo sale.order records in draft state. Fergus quote line items map to sale.order.line records. The Fergus quote status (draft, sent, accepted, declined) maps to Odoo's state field (draft, sent, sale_order, cancel) with a manual status review step before go-live.
Fergus
Job
Odoo CRM
crm.lead (Opportunity)
1:1Fergus Jobs map to Odoo crm.lead records with type='opportunity'. The job name becomes the opportunity name. Job status maps to crm.stage using Odoo's default stage pipeline (New, Qualified, Proposal, Negotiation, Won, Lost). Fergus job-assigned staff map to Odoo's user_id via email match.
Fergus
Job Line Item
Odoo CRM
sale.order.line / crm.lead
1:manyFergus job line items with a service description split into two Odoo records: the service line becomes a sale.order.line with the linked product, and the labour description becomes a note on the crm.lead record. Material and labour amounts are stored in separate x_material_amount and x_labour_amount custom fields for reporting continuity.
Fergus
Pricing Tier
Odoo CRM
product.pricelist / res.partner
1:1Fergus Pricing Tiers do not have a direct Odoo equivalent. Each tier's rate rules are exported as Odoo Pricelist rules on the product.product record. Unmatched tier rates are stored as a JSON-formatted custom field (x_pricing_tier_rules__c) on the res.partner for manual Pricelist recreation in Odoo Studio.
Fergus
Invoice
Odoo CRM
account.move
1:1Fergus Invoices map to Odoo account.move records of type='out_invoice'. Line items map to account.move.line with debit/credit based on the Fergus invoice amount and tax configuration. Fergus invoice status (paid, overdue) maps to Odoo's payment_state field using value mapping.
Fergus
Asset / Equipment
Odoo CRM
maintenance.equipment
1:1Fergus Assets at a client site map to Odoo maintenance.equipment records linked to the client res.partner via the partner_id field. The asset name, serial number, and location fields map directly to Odoo's name, serial_no, and location fields.
Fergus
Staff / User
Odoo CRM
res.users
1:1Fergus Staff records map to Odoo res.users by email match. Active staff get Odoo user accounts with the CRM extension rights. Inactive or archived staff are created as Odoo portal users so historical job attribution is preserved without granting internal access.
Fergus
Quote Attachment
Odoo CRM
ir.attachment
1:1Fergus files attached to Quotes and Jobs are downloaded and re-uploaded to Odoo ir.attachment records linked to the corresponding sale.order or crm.lead via res_model and res_id. Odoo's default 25MB per-file limit applies; files exceeding this are flagged before migration.
Fergus
Quote Workflow / Sequence
Odoo CRM
None
1:1Fergus workflows that trigger job creation when a quote is accepted do not transfer. The automation logic must be rebuilt in Odoo using Studio automation rules or server actions triggered on sale.order state change to 'sale_order'.
Fergus
Payment Integration Settings
Odoo CRM
None
1:1Fergus payment gateway configuration (Stripe, PayPal links) does not migrate. Odoo's payment providers are configured independently in Accounting > Configuration > Payment Providers. We provide a rebuild checklist with the Fergus payment provider names and credentials for your Odoo admin to re-enter.
Fergus
Settings / Business Config
Odoo CRM
None
1:1Fergus business-wide settings such as default tax rates, invoice numbering sequences, and default job templates do not have Odoo equivalents that migrate automatically. These are documented in a settings export sheet for manual configuration in Odoo Accounting and CRM settings screens.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Fergus gotchas
100 req/min API rate limit constrains bulk exports
Customer pricing tier data requires explicit mapping
Quote and invoice warning badges are state-dependent
No documented public schema for custom fields
Job photos and attachments require separate file export
Odoo CRM gotchas
Odoo.sh version gating blocks assisted migrations from trial
Enterprise modules fail to install on Community after database restore
Custom module view inheritance breaks between Odoo major versions
Custom fields risk losing their application context on Community
API access for Community is gated behind the Custom Plan
Pair-specific challenges
Migration approach
Audit Fergus API schema and export full object graph
FlitStack connects to the Fergus REST API using your company credentials and enumerates all objects: Clients, Contacts, Quotes, Quote Line Items, Jobs, Job Line Items, Invoices, Assets, Staff, and Pricing Tiers. We validate foreign-key integrity before extraction and identify any objects that exceed the 100 req/min rate limit under batched export. A pre-migration data quality report flags duplicate clients, missing email addresses on contacts, and orphaned job records that need resolution before the migration runs.
Build Odoo target schema: res.partner, sale.order, crm.lead, account.move
Before loading any data, FlitStack creates the custom fields required on Odoo models: x_job_number__c on crm.lead, x_pricing_tier_rules__c on res.partner, x_original_create_date__c on all migrated models, and x_asset_id__c on crm.lead. The Odoo Pricelist structure is documented using the Fergus Pricing Tier export so your admin can create the Odoo Pricelists before the full run. All custom fields use the x_ prefix following Odoo naming conventions for non-managed fields.
Load partners and contacts before quotes and jobs
The migration runs in strict dependency order: res.partner (Clients) first, then res.partner (Contacts with parent_id set), then sale.order (Quotes) referencing partner_id, then crm.lead (Jobs) referencing the partner and optional sale_order relation, then account.move (Invoices), and finally maintenance.equipment (Assets) with their linked partners. This ordering ensures Odoo's many2one foreign-key constraints are satisfied at each step. Any record that fails validation is logged to a mismatch report and retried after manual review.
Run a sample migration with field-level diff on 100–500 records
A representative slice of Fergus data — spanning at least 5 clients, 10 contacts, 5 quotes, 5 jobs, and 2 invoices — is migrated to Odoo and compared field-by-field against the source. The diff report surfaces any value-mapping gaps (e.g., Fergus status values not in the Odoo stage mapping table), missing custom fields, and pricing tier preservation failures. You review the sample diff and approve field mapping rules before the full run commits.
Execute full migration with delta-pickup window and rollback plan
The full migration loads all Fergus records into Odoo using the approved mapping rules. A delta-pickup window of 24–48 hours after the initial load captures any new or modified Fergus records (new quotes, updated jobs) created during the cutover. FlitStack maintains a full audit log of every write operation. If reconciliation fails — for example, a pricing tier was missed — one-click rollback reverts all Odoo records to their pre-migration state so the run can be corrected and re-executed without data loss.
