Odoo Customisation in London

Adapting Odoo to how London 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

London

London clients usually come to us because they want senior people actually on their project rather than a large agency's B team, and because Midlands rates buy considerably more delivery per pound.

Odoo Customisation in London — 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 Greater London?
Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of London businesses do you usually work with?
Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
Do you cover the areas around London?
Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
