Odoo Development in Chelmsford
Building custom modules for Chelmsford businesses running Odoo, where computed fields are the feature most often got subtly wrong. A computed field only recalculates when something it declares a dependency on changes — declare the wrong ones and the value quietly goes stale, showing a figure that was correct at some point in the past.
Why this comes up
The problem
A calculated total is wrong on some records and right on others, and nobody can find a pattern in which ones.
What you get
What we deliver
- Computed fields written with complete and accurate dependencies
- Stored versus non-stored decided per field, since it affects searching and speed
- Operations written against recordsets rather than looping record by record
- Modules structured to inherit standard behaviour instead of replacing it
- Access rules and record rules defined for anything the module introduces
- Code version controlled and deployable, not edited on the server

Odoo Development in Chelmsford — common questions
- Why do computed fields go stale?
- Because recalculation is triggered by declared dependencies, not by anything changing. If a computation reads a field it never declares, Odoo has no reason to recompute when that field changes — and the stored value stays as it was, indefinitely and silently.
- Should computed fields be stored?
- Store them when you need to search, sort or group on the value, and accept the recomputation cost. Leave them unstored when they are display-only, which avoids writing to the database every time a dependency changes across a large table.
- What is the usual performance mistake?
- Looping over records and writing to each one individually. The ORM is built to act on a whole recordset at once, and a per-record loop turns one database operation into thousands — fine in testing, painful on a real dataset.
- Do custom modules need their own access rules?
- Yes. A new model with no rules is either invisible or open depending on configuration, and neither is what you meant. Defining access and record rules alongside the model is part of building it, not a hardening step afterwards.
- Do you work with businesses across Essex?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout East of England, including Chelmsford and the surrounding Essex area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Chelmsford businesses do you usually work with?
- Professional services systems and hybrid-working setups for firms whose staff split time between here and London. Beyond that we work across Financial Services, Professional Services, Retail, Construction and Public Sector.
- Do you cover the areas around Chelmsford?
- Yes — we work throughout East of England, including Colchester, Southend, London. Chelmsford is an urban area of roughly 180,000+, and we take on work across the wider Essex region rather than the city boundary alone.
