Overview
Spectrum ERP and Odoo ERP serve different primary use cases: Spectrum is construction-vertical with deep job costing, union payroll, and certified payroll built into the core. Odoo is a horizontal, modular ERP that covers accounting, inventory, manufacturing, CRM, and project management in one platform and scales from a small business to an enterprise deployment. The migration is not a module-for-module replacement — it is a data reconstruction that preserves Spectrum's project phase and cost-code hierarchy inside Odoo's analytic accounting model, remaps certified payroll rules into Odoo's HR and payroll structure, and extracts both sides of every G/L journal entry so the trial balance is audit-ready at cutover. We do not migrate automations, workflows, or SQL-level customizations; we deliver a written inventory of these for the customer's admin to rebuild in Odoo's action-automation framework.

Object mapping
Each row shows how a Spectrum 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.
Spectrum ERP
Project / Job
Odoo ERP
Project
1:1Spectrum Jobs map to Odoo Project records with the job's phase and cost-code hierarchy preserved through Odoo's Analytic Account structure. Each Spectrum cost code becomes an Analytic Account line or a Cost Center tag depending on the customer's Odoo configuration. We extract the full job hierarchy — parent job, phases, and cost codes — during scoping and reconstruct it as nested Odoo Projects or as a flat project with analytic distribution lines. Historical job cost totals carry over as project financial data so that the new system reflects the current state of every project at cutover.
Spectrum ERP
Work Order
Odoo ERP
Task or Project Task
1:1Spectrum Work Orders map to Odoo Project Tasks attached to the corresponding Project. Work order labor, materials, and equipment allocations migrate as Task Line items or as a linked Manufacturing Order if the work order governs production. We preserve the work order number, description, scheduled dates, and any linked notes or images via Odoo's document attachment model. Equipment allocation from the work order links to the Equipment record in Odoo's Maintenance app if that module is deployed.
Spectrum ERP
Chart of Accounts / G/L Account
Odoo ERP
Account
1:1Spectrum G/L Account structure maps to Odoo's Chart of Accounts using a pre-migration mapping session that defines account codes, account types, and any segment-level splits. If Spectrum uses multi-segment account codes (e.g., 4-1234-56), we either preserve the full segment as the Odoo account code or split it into Odoo's account-plus-analytic-tag model depending on the customer's reporting requirements. Account rollup hierarchies migrate as parent-child relationships in Odoo.
Spectrum ERP
G/L Journal Entry (both sides)
Odoo ERP
Journal Entry
1:1Every G/L Journal Entry in Spectrum extracts via the Add G/L Journal Entries web service, which surfaces both debit and credit lines in a single call. We validate that total debits equal total credits before writing to Odoo and flag any entries that fail this check for customer-side correction before cutover. Journal entries carry their original posting date, reference number, and description. Historical journal entries populate Odoo's General Ledger so that trial balance reports reconcile from day one of the destination system.
Spectrum ERP
Accounts Receivable / Customer Record
Odoo ERP
Contact (Customer)
1:1Spectrum A/R Customer records map to Odoo Contact records with the Customer flag enabled. Open invoice data, credit limits, and payment terms migrate as Contact properties or as related Account Receivable records in Odoo's Accounting app. Customer-specific GL assignment codes from Spectrum carry over as analytic tags on the Contact record.
Spectrum ERP
Accounts Payable / Vendor Record
Odoo ERP
Contact (Vendor)
1:1Spectrum A/P Vendor records map to Odoo Contact records with the Vendor flag enabled. Vendor-specific payment terms, bank details, and W-9 or tax registration data migrate as vendor properties. Any vendor-specific cost-code assignments from Spectrum carry over as analytic tags to route AP transactions to the correct job cost account in Odoo.
Spectrum ERP
Payroll / Pay Stub
Odoo ERP
Employee + Payroll Run
1:1Spectrum employee records migrate to Odoo Employees with employment dates, department assignments, and compensation data. Pay stubs and payroll runs migrate as Odoo Payroll Runs with earnings, deductions, and taxes preserved. Certified payroll fields — union rules, prevailing wage rates, fringe benefit allocations — require remapping to Odoo's payroll structure because Odoo's standard payroll module uses a different deduction code model. We flag every certified payroll field identified during scoping and document the mapping to Odoo's HR and payroll configuration so that the customer's payroll administrator can validate before go-live.
Spectrum ERP
Equipment / Equipment Work Order
Odoo ERP
Equipment + Maintenance Request
1:1Spectrum Equipment records map to Odoo Maintenance app Equipment records with preventive maintenance schedules, work order components, and notes preserved. Equipment Work Orders migrate as Odoo Maintenance Requests linked to the Equipment record. Any labor and parts costs recorded against equipment work orders in Spectrum carry over as maintenance log entries on the Odoo Equipment record.
Spectrum ERP
Inventory / Stock Item
Odoo ERP
Product / Stock Move
1:1Spectrum Inventory records map to Odoo Products with the inventory valuation method preserved (FIFO, standard cost, or average cost depending on what Odoo modules are deployed). Open purchase orders and their lines migrate to Odoo Purchase Orders with vendor, product, quantity, and scheduled date intact. Current stock levels migrate as Odoo Inventory Quant records so that the physical inventory position is correct at go-live.
Spectrum ERP
Service Request Custom Fields
Odoo ERP
Custom Fields on Project or Task
1:1Spectrum Service Hub allows up to four custom fields per Service Request form. We extract all four-field configurations during scoping, including field definitions, data types, and current values. Custom fields map to Odoo Project or Task custom fields (Char, Integer, Selection, or Boolean depending on the Odoo module version). If the destination Odoo deployment allows more than four custom fields, we carry over the full set; if it enforces a four-field limit, we document which fields are highest priority for preservation.
Spectrum ERP
Document Imaging / Images
Odoo ERP
IrAttachment
1:1Project Log Images, Work Order Images, and Employee Images from Spectrum's Document Imaging web services migrate as Odoo IrAttachment records linked to the corresponding Project, Task, or Employee. Binary image data requires a separate transfer pass after relational data is loaded so that parent record IDs are available for attachment linkage. We extract image metadata (filename, content type, creation date) alongside the binary data.

Migration approach
Discovery and module scope definition
We audit the Spectrum tenant across all active modules — A/R, A/P, Payroll, Project Management, Inventory, Equipment — and identify which are in daily use versus configured but unused. We extract record counts per module, identify custom fields in Service Hub, review the Chart of Accounts segment structure, and map the certified payroll configuration if the Payroll module is active. We pair this with an Odoo edition assessment: Community for companies that need core accounting and project management without recurring licensing costs; Enterprise for companies that require the Payroll, Manufacturing, or Quality Control apps. The discovery output is a written migration scope document with module-level record counts and a data-priority ranking.
Analytic accounting design session
Spectrum stores job cost codes as part of the GL account hierarchy. In Odoo, the chart of accounts is separate from analytic accounts, which gives construction companies more flexibility to report the same GL account across multiple projects and cost codes simultaneously. We run a mapping session with the customer's project manager and accountant to define how Spectrum's job-cost code hierarchy maps to Odoo's analytic account structure. This session determines whether the migration uses nested Odoo Projects, flat projects with analytic distribution lines, or a combination. The design is documented and validated against the customer's current job cost reporting before migration begins.
Pre-migration data cleansing and SQL backup extraction
We recommend running a structured API extraction from Spectrum rather than relying solely on Trimble's SQL backup export, which delivers raw database tables without the relationship context between records. We extract data in dependency order — Chart of Accounts first, then Customers and Vendors, then Projects and Work Orders, then Journal Entries — and validate referential integrity at each step. We identify duplicate vendor and customer records, inconsistent GL account codes, and open invoices with mismatched amounts during this phase. Data quality issues are documented in a cleansing report for the customer's accounting team to resolve before migration. This step also serves as the structured extraction that should begin before the 30-day post-termination window if the customer is in the notice period.
Odoo sandbox configuration and schema deployment
We configure the destination Odoo environment with the chart of accounts, analytic account structure, and tax codes defined during the design session. We set up the relevant apps — Accounting, Project, Maintenance, Inventory, and Payroll (if Enterprise) — and configure the Odoo user access levels to match the customer's role structure from Spectrum. The migration team deploys the configuration to a staging environment that mirrors the production Odoo setup and runs a validation pass with a subset of data before committing to production deployment.
Production migration in dependency order
We run production migration in a strict sequence: Chart of Accounts and G/L Journal Entries (both sides together, with debit-credit validation), Customers and Vendors, Projects and Work Orders, Inventory and Stock, Equipment and Maintenance Records, Employee records and Payroll history, and finally any Document Imaging files. Each phase emits a reconciliation report comparing record counts in Spectrum against Odoo counts before the next phase begins. We use Odoo's batch import tools with CSV templates for high-volume record types and XML-RPC API calls for records requiring relationship resolution at insert time.
Cutover, trial balance validation, and automation handoff
We freeze Spectrum writes during cutover, run a final delta extraction of any records modified during the migration window, and validate the Odoo trial balance against the Spectrum trial balance as of the cutover date. We deliver a written inventory of Spectrum automations and customizations — including any PRO-IV framework customizations, workflow rules, and certified payroll configurations — with Odoo equivalent recommendations. We support a one-week post-cutover validation window where we resolve any record discrepancies raised by the customer's team. We do not rebuild Spectrum automations as Odoo server actions or automated tasks inside the migration scope; that work is handled separately by an Odoo partner or the customer's admin team.
