Short answer: A failed Odoo implementation, or one that never closes, usually comes down to management rather than technology: no clear scope, no project owner, endless customization, dirty data, no acceptance criteria, a changing team and a budget that runs out. You can reduce these risks before the project starts, through the contract and the plan. Deep Vision, an Odoo Gold Partner from Tashkent, splits projects into phases and closes each one with a defined result.
“The project has been running for two years and Odoo still doesn't fully work” is something many business owners say. A failed Odoo implementation is not always a dramatic collapse. More often it happens quietly: deadlines slip, new requirements pile up, staff keep working in Excel, and the project is never formally closed. This article covers seven reasons projects stay unfinished, how to prevent them and what to look for in a partner.
How often do Odoo implementations fail?
A failed Odoo implementation is a project that missed its deadline, budget or business goals, and most often dragged on without ever being formally closed.
This is not unique to Odoo. Gartner expects that by 2027 more than 70% of recently implemented ERP initiatives will fail to fully meet their original business goals (Gartner). A Gartner analyst put it more sharply in 2025: 70% fail to fully meet business case goals, and 25% fail catastrophically (The Register).
McKinsey and the University of Oxford studied more than 5,400 IT projects and found that large projects run on average 45% over budget and 7% over time, and deliver 56% less value than predicted. One key finding: every additional year of duration adds another 15% to cost overruns (McKinsey). A project that drags on is not just late. It keeps getting more expensive.
What are the 7 reasons Odoo projects never close?
1. No clear scope
The project starts with a vague goal like “move everything into Odoo.” Nobody writes down which processes, modules and reports belong in phase one. Every meeting widens the scope, and the finish line never appears.
2. No project owner on the client side
If no one at the company makes decisions and makes time for the project, questions sit unanswered for weeks. The provider waits and deadlines slip. A project owner is not an IT person but a manager who can change how processes work.
3. Endless customization
Every “we do it differently” becomes new custom code. The more code there is, the harder testing, bug fixing and version upgrades become. A configuration project turns into a software development project.
4. Dirty data
Duplicate products, wrong stock balances, an outdated customer base. If data is migrated without cleanup, Odoo shows wrong numbers from day one and staff stop trusting it.
5. No acceptance criteria
When is a phase finished? If you never agreed that “the phase is accepted when these 20 scenarios work,” each side has its own idea of done, and the project never closes.
6. The provider's team changes
The specialist who started the project leaves, and a new one carries on without documentation. Knowledge is lost, decisions are reopened and some work is redone.
7. The budget runs out
In an hourly, uncontrolled project, money runs out before results arrive. Remaining work is postponed “for later,” and the system runs half-finished. On how pricing works: Odoo ERP cost in Uzbekistan.

How do you structure a project so it actually closes?
Use this list to check yourself at the start.
- Is the scope of phase one written down (modules, processes, reports)?
- Is there a named project owner on your side who makes decisions?
- For every non-standard request, did someone ask “can standard Odoo do this?”
- Is there a separate plan and owner for data cleanup and migration?
- Are acceptance scenarios (UAT) agreed in advance for each phase?
- Does the provider keep project documentation and hand it over to you?
- Are payments tied to results, meaning phase acceptance?
- Is there a change-request process for anything outside scope?
- Are the go-live date and the parallel-run period defined?
A phased approach is the most reliable: launch core processes such as Sales and Inventory first, then add the rest. More on phases: Odoo ERP implementation guide.
What should you do if the project has already stalled?
First, stop and assess the situation honestly. Which processes really run in Odoo, and which are still in Excel? Which custom modules are in use, and who holds their source code? List the remaining work and sort it into essential, useful and unnecessary. Then set a short phase for the essential items only, with clear acceptance scenarios and a deadline. Rescuing a project rarely means starting over: a proper audit and a firm scope are usually enough.
How can you check a partner's track record of closing projects?
Closing projects is a skill built by carrying many implementations to completion. One public way to check it is the odoo.com partner directory. Odoo's official requirements (odoo.com):
- Ready: 10 new Enterprise users per year, 1 certified staff member, no retention minimum.
- Silver: 75 new users per year, 3 certified staff, at least 70% retention.
- Gold: 300 new users per year, 6 certified staff, at least 80% retention.
Three hundred new users a year means many projects have actually gone live and people are working in the system. Retention shows that clients stay with the partner after the project. If a provider is not in the directory at all, or has no references, it cannot openly show finished projects.
How does Deep Vision close projects?
Deep Vision is an official Odoo Gold Partner from Tashkent. Its Odoo partner directory page (checked 13 October 2026) lists 7 certified experts, 20+ client references and 89% retention. The Gold tier itself requires a large yearly volume of delivered Enterprise users, which means a steady flow of closed projects.
How we work:
- Every project starts with diagnostics and a written scope.
- Work is split into phases: a typical rollout takes 2 to 6 months, and standard Sales and Inventory often go live in 6 to 8 weeks.
- Standard Odoo first; custom code only when it is justified.
- Ready modules for Didox and Asl Belgisi shorten the timeline.
- Each phase is closed with acceptance scenarios.
- The team includes experienced senior specialists who know industries and finance.
One result: at Timsoll, with 18 branches and 7,000+ SKUs, setting up a new product went from 6 to 8 months down to 2 to 3 days (case study).

Frequently asked questions
What is the most common reason an Odoo implementation fails?
Most often, unclear scope and endless customization. Both leave the project without a finish line.
Can a stalled project be rescued?
Yes. Start with an audit: what works, what does not, which code is really needed. Then split the remaining work into clear phases and close each against acceptance criteria.
How long should an Odoo project take?
In Deep Vision's experience, a typical rollout takes 2 to 6 months. Standard Sales and Inventory often go live in 6 to 8 weeks.
Why do milestone payments matter?
When payment is tied to phase acceptance, both sides focus on a concrete result and the budget stays under control.
How do I know a partner has closed many projects?
Check the tier, references and retention in the Odoo partner directory, and talk to the clients listed as references.
