ERP Development
ERP Development on Odoo
Custom ERP solutions built on Odoo's framework — when off-the-shelf modules don't fit your business and you need a tailored multi-module system maintained as code. Senior Python + OWL engineers, upgrade-safe patterns.

What it is
Custom ERP solutions built on Odoo's Python ORM + OWL frontend framework. We treat Odoo as the platform, not the product — using its accounting, inventory, HR, and other base modules for free while building tailored business logic on top. Output is a multi-module system that's yours, lives in your Git repo, and survives Odoo version upgrades because we follow recommended extension patterns.
Why it matters
Off-the-shelf SaaS doesn't fit every business. Building from scratch is expensive and slow. Odoo's framework (with proven base modules for the boring stuff like accounting and HR) lets you focus development effort on the parts of your business that are actually differentiated — usually 20% of the workflow that creates 80% of the value. Result: production-grade ERP for the price of building only the differentiated part.
Features
-
Senior-only engineering
Every developer is a 5+ year Odoo specialist. No junior devs cutting their teeth on your codebase; no rotating cast through a managed-service queue.
-
Upgrade-safe by default
We follow Odoo's official extension patterns so custom code survives major-version upgrades. Tests run against the Odoo CI image.
-
Multi-module architecture
Domain-driven module boundaries reviewed in an upfront architecture workshop. Inter-module dependencies kept clean; no spaghetti.
-
Fixed-scope, fixed-price
After a one-week paid spike on the riskiest piece, we quote fixed-scope. Change requests go through documented change-control.
-
Code in your repo
All code lands in your Git repo from day one. Code review is real (with comments and rejections, not rubber-stamping). Your engineers can join PRs at any point.
-
Test coverage on every PR
Unit, integration, and end-to-end tests for all custom code. Tests run on Odoo's CI image to catch upgrade breakage early.
-
Production-grade defaults
Structured logging, error reporting, feature flags, and CI/CD pipeline ship by default — not as 'nice to haves' you discover are missing six months in.
-
Documentation
Architecture decision records (ADRs), per-module README, API docs, and admin runbooks. Everything a new developer needs to onboard solo.
How it works
-
Architecture workshop
Two-day workshop with engineering leadership. We map proposed system, decide module boundaries, and identify riskiest unknowns.
-
Spike on highest-risk piece
One-week spike on the technically riskiest piece. De-risks the estimate and gives you a working prototype before signing for full scope.
-
Fixed-scope quote
After the spike, written fixed-scope quote with module breakdown, dependency graph, and assumptions called out.
-
Iterative build
Two-week sprints with weekly demos and continuous PR review. Your engineers can join PRs or contribute directly.
-
User acceptance + load testing
UAT with real users + load testing against representative data volumes. Performance issues fixed before production.
-
Production rollout + 30-day stabilization
Phased rollout (canary → small cohort → full) with feature flags. Free bug-fix window for issues uncovered in production.
Deployment timeline
Most ERP-development engagements run 6–16 weeks of build time. Smaller scopes (2–3 modules, no third-party integrations) ship in 6–8 weeks. Larger systems with new APIs, OWL frontends, and multi-module dependencies run 12–16 weeks. The architecture workshop and one-week spike happen upfront; you get a working prototype within 2 weeks of contract.
Best for
Engineering-aware businesses building a meaningful custom system on top of Odoo — vertical SaaS products, internal ops tools that need deep ERP integration, or multi-module workflows beyond what Odoo Studio can handle. Less useful for teams who only need 1–2 small features (Odoo Customization fits better) or teams without engineering leadership to act as a counterpart.
Frequently asked questions
-
How is this different from Odoo Customization?
Customization is smaller-scope: tweaks to existing modules, custom workflows, custom reports — typically 2–6 weeks. ERP Development is larger: building entire new modules, custom apps, or vertical SaaS extensions — typically 6–16 weeks. Customization usually has a configurator running it; ERP Development has a senior engineer with architectural responsibility.
-
Will the code be upgrade-safe?
Yes — we follow Odoo's official extension patterns (inheriting from base models, upgrade-safe field definitions, avoiding monkey-patching) specifically so custom code survives major version upgrades. We've taken clients from Odoo 15 to 19 with minimal rework.
-
Can your developers work alongside our engineering team?
Yes — hybrid engagements where TechUltra developers contribute alongside your in-house engineers are common. PRs flow into your repo, code review is shared, onboarding documentation is mutual. For long-term embedded resources, see Hire Odoo Developer.
-
Can you build a public API on top of Odoo?
Yes — REST and GraphQL APIs from Odoo for partner integrations, mobile apps, or external client systems. Auth, rate-limiting, observability, and documentation are part of standard scope.
-
What about technical debt in our existing custom code?
We audit before quoting and share findings so you know the state of the system before paying for changes. Sometimes the right answer is to rewrite a problematic module before adding new features; sometimes wrap-and-contain is better. We share both options and let you choose.
-
How is pricing structured?
Fixed-scope and fixed-price after the one-week spike. The spike is paid (~$5–10k typically) and de-risks the full estimate. Most engagements are quoted in two-week sprints; you can pause, scale, or end at any sprint boundary.
-
Implementation timeline?
Architecture workshop + spike: 2 weeks. Build: 4–14 weeks depending on scope. UAT + load testing: 1–2 weeks. Production rollout + 30-day stabilization: 4 weeks. Total: 8–20 weeks for most engagements.
