Odoo Customisation in Derry

Adapting Odoo to how Derry businesses work, with one principle doing most of the work: extend rather than replace. Odoo's inheritance model lets a custom module add to standard behaviour without editing it — and modifications built that way survive upgrades, while modifications that override core code have to be rewritten each year.

Why this comes up

The problem

Core files were edited to make one screen behave differently, and the annual upgrade now requires undoing and redoing all of it.

What you get

What we deliver

  • Changes delivered as separate modules that inherit rather than replace
  • Core files left untouched, so upgrades apply cleanly
  • Standard behaviour used wherever the process could reasonably adapt to it
  • Studio changes reviewed, since they are convenient and easy to lose track of
  • Each customisation justified against the cost of carrying it through upgrades
  • Custom modules documented and version controlled like the software they are

Odoo Customisation in Derry — common questions

What does extending rather than replacing mean?
Building a module that inherits from a standard one and adds or adjusts specific behaviour, leaving the original intact. The upgrade then updates the standard code beneath your addition, and only your change needs checking rather than the whole feature.
Is Studio a good way to customise?
For small adjustments, yes, and it is easy to accumulate changes nobody has recorded. Studio modifications are real changes that affect upgrades, so they need the same visibility as anything a developer writes rather than being treated as configuration.
How do we decide what is worth customising?
Weigh it against carrying it forward annually. A modification saving ten minutes a week may cost more than that in upgrade effort over three years, whereas one removing a genuine process obstacle repays itself regardless.
Should custom modules be version controlled?
Always. They are source code with the same needs — history, review, the ability to deploy the same thing to test and production. Custom modules living only on the server are a single failure away from being unrecoverable.
Do you work with businesses across County Londonderry?
Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Derry businesses do you usually work with?
Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
Do you cover the areas around Derry?
Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
