Odoo Development

An Odoo development company that won't customise you out of an upgrade path

BinaryBrill is an Odoo development company delivering accounting, inventory, purchasing and sales that work on day one, with custom modules built only where your process is genuinely distinct. Our Odoo implementation services and custom Odoo module development come from in-house senior engineers who write modules to sit alongside the core, so the Odoo ERP consultant you talk to next year isn't stuck untangling a fork.

A senior engineer replies within 24 hours — not a sales rep.

Where Odoo projects usually go wrong

Someone forked the core to save a week

A previous developer edited core Odoo files directly instead of building a proper module, and it worked fine until the next version upgrade tried to overwrite those files. Now every update is a manual merge exercise, and the team has quietly stopped upgrading at all, which is its own accumulating risk.

The instance was customised before it was configured

Custom fields and modules were built for requirements that standard Odoo already covers with a setting most implementers never checked. The result is a system that's harder to maintain than it needed to be, for capability the platform gave away for free.

Modules were installed and nobody owns them

A community app was added two years ago to solve a specific problem, the person who chose it has left, and nobody knows if it's still receiving updates, whether it's compatible with the version you're planning to move to, or what happens if you remove it.

The migration keeps getting postponed

You're several versions behind, deprecated modules are propping up daily operations, and the longer the gap grows the riskier and more expensive the eventual migration becomes. Everyone agrees it needs doing. Nobody wants to be the one who breaks invoicing during the attempt.

How we approach Odoo development

Odoo is often the cheapest honest answer for a growing business, but only if it's implemented with restraint. We configure hard before we build, and build in a way that doesn't fight the next upgrade.

Configure the standard app before writing a module

Odoo's accounting, inventory, purchasing and sales apps already model most of what a growing business does. We check what a setting, a report filter or a standard workflow already covers before proposing custom development, because configuration survives an upgrade for free and code has to be maintained forever.

Modules that extend, never modify, the core

Custom development happens through Odoo's own module and inheritance mechanisms, never by editing core files directly. That's the difference between a version upgrade being a scheduled afternoon of regression testing and a two-month rebuild of everything that was patched in.

Migrations treated as a project with a rehearsal

Moving a heavily customised instance forward a major version is run against a copy first, with every custom module checked for compatibility and every data table reconciled before the real cutover. We'd rather find the breakage in a staging instance than on the Monday morning after go-live.

Hosting and monitoring that don't get forgotten

Whether you run on Odoo.sh or your own infrastructure, backups, monitoring and a patching schedule are part of the setup, not something added after the first outage. An ERP that's down is worse than the spreadsheet it replaced.

What this covers

Pick the piece you need, or bring us the problem and we'll tell you which applies.

Odoo Implementation Services

Implementation and configuration across accounting, inventory, purchase, sales and manufacturing, sequenced so each module is usable on its own rather than delivered as one large go-live. We configure the standard app fully before recommending any custom work.

  • Implementation and configuration across accounting, inventory, purchase, sales and manufacturing
  • Phased rollout by module or site, so the business keeps trading throughout
  • Chart of accounts, warehouse and pricing structures set up to match how you actually operate
  • Odoo ERP consultant guidance on which apps genuinely replace your current spreadsheets

Custom Odoo Module Development

Custom modules for the parts of your process standard Odoo genuinely doesn't cover, built through Odoo's own inheritance and extension mechanisms rather than by editing core files. The test for every module we write is whether it still works after Odoo's next major release.

  • Custom modules written to survive version upgrades rather than block them
  • Development following Odoo's module and inheritance conventions, never core file edits
  • OWL and QWeb front-end work for interfaces the standard views can't express
  • Code reviewed against the next major Odoo release before it ships

Odoo Version Migration

Moving instances forward through Odoo versions, including heavily customised ones where every custom module has to be checked for compatibility before the upgrade touches production. We rehearse the migration against a full copy of your data first.

  • Version migrations, including moving heavily customised instances forward
  • Custom module compatibility checked and fixed against the target version before cutover
  • Full-copy rehearsal migrations run until reconciliation is clean
  • A documented rollback path if the live migration surfaces something the rehearsal didn't

Odoo Integration Services

Connecting Odoo to e-commerce platforms, banking feeds, shipping carriers and other systems you're keeping, through the Odoo External API or webhooks where available, and file exchange where a partner offers nothing better.

  • Integration via the Odoo External API, XML-RPC/JSON-RPC and webhooks
  • E-commerce, banking and carrier integrations that reconcile rather than assume success
  • EDI and file-based exchange for partners without a modern API
  • Monitoring and alerting so a failed sync is caught the same day

Odoo Hosting, Support & Managed Services

Hosting on Odoo.sh or your own infrastructure, with backups, monitoring and a patching schedule in place from day one, plus ongoing support for the routine changes every ERP needs as the business keeps moving.

  • Hosting on Odoo.sh or your own infrastructure, with backups and monitoring in place
  • A defined response time for production issues versus routine change requests
  • Patch and security update management that doesn't wait for an incident
  • Admin training so day-to-day configuration changes don't need to come to us

How we'll work together

Every stage ends with something in your hands — not a status update.

  1. 01

    Audit and process discovery

    We review your current instance (or your spreadsheets, if you're starting fresh), map how accounting, inventory, purchasing and sales actually need to work, and identify what standard Odoo covers versus what's a genuine custom requirement.

    You get: A configuration-versus-custom-module recommendation, a scoped app list, and a written cost comparison between the two paths.

  2. 02

    Configure and build in a sandbox

    Standard apps are configured first against your chart of accounts, warehouses and pricing structure. Custom modules are then built for the genuine gaps, developed against a copy of your real data so the sandbox behaves like the eventual production system.

    You get: A working staging instance with configured apps, custom modules under test, and sprint demos your team can react to.

  3. 03

    Migrate data and rehearse go-live

    Historical data is cleaned and loaded into staging repeatedly until the opening balances reconcile. For version migrations, we run the upgrade against a full copy first and resolve every compatibility issue in custom modules before touching production.

    You get: A reconciled data migration report, a rehearsed upgrade with issues resolved, and a documented cutover plan with rollback steps.

  4. 04

    Go live, host and support

    Cutover happens on a planned date with the old system available as a fallback. Hosting is set up on Odoo.sh or your infrastructure with backups and monitoring live from day one, and we stay close through the first close or stock count.

    You get: A production Odoo instance with monitoring and backups configured, role-based training, and a support handover pack.

Where we've applied this

Manufacturing

Bills of materials, work orders and shop-floor consumption tracked in Odoo Manufacturing, tied to real stock levels rather than a supervisor's estimate.

Retail & wholesale

Point of Sale, e-commerce and warehouse stock reconciled in one ledger, so a shop-floor sale and an online order tell finance the same story.

Logistics & distribution

Multi-warehouse inventory with batch and lot tracking, and purchasing rules tuned to real supplier lead times instead of a fixed reorder point.

Professional services

Timesheets, project costing and invoicing connected end to end, so utilisation and margin are visible before the month closes rather than after.

Construction & real estate

Project-based purchasing and subcontractor billing tracked against budget per job, inside the same system as the general ledger.

Healthcare & consumer goods

Expiry and lot-controlled inventory for regulated stock, with procurement approvals that leave an audit trail rather than an email chain.

Questions buyers ask us

Is Odoo the right fit for us, or should we look at a bigger ERP platform?

Odoo tends to be the stronger choice for growing businesses whose processes are reasonably close to standard practice — you get accounting, inventory, purchasing and sales that work on day one at a fraction of the licensing cost of SAP or Dynamics. It's a weaker fit if your operations are genuinely unusual across every module, where the customisation needed would be as extensive as a bespoke build. We assess this honestly in discovery rather than assuming Odoo is the answer because it's what we were asked about.

Enterprise adds modules like advanced manufacturing, field service and some reporting that Community doesn't have, plus official support from Odoo itself. For custom module development the underlying framework is the same either way, so the choice comes down to whether the Enterprise-only apps genuinely matter to your operation, not which one is easier to build on.

How close your processes sit to Odoo's standard workflow, how many custom modules are genuinely needed, and how messy the data being migrated in is. A configuration-only implementation is inexpensive; a project with several custom modules and three external integrations costs more because each of those needs its own testing and maintenance plan. We price firmly after the audit, not before it.

Usually yes, but it's rarely a single jump. We assess how many versions behind you are, audit every custom module for compatibility with the target version, and often migrate through intermediate versions rather than attempting one large leap. The rehearsal migration against a full data copy is what tells us the real scope before we commit to a date.

When a configuration change, a report filter, or an existing community app already does the job — building bespoke for something the platform gives away free is money spent for no benefit. We'd also push back on a custom module that requires editing core files to work; if a requirement can only be met that way, it usually means the requirement needs rethinking, not the core.

Through Odoo's own access rights and record rules, configured against your actual policy rather than left on defaults, and through the hosting choice itself — Odoo.sh, your own cloud account, or on-premises, depending on your data residency requirements. Integrations move only the fields a receiving system needs, and we document exactly what leaves the instance and where it goes.

A focused implementation of core apps — accounting, inventory, sales — for a straightforward business typically lands in six to ten weeks. Projects with several custom modules or a version migration alongside the implementation run longer, and we phase the rollout so you're using something useful well before the whole programme finishes.

Our own in-house engineers in Sahibzada Ajit Singh Nagar, Punjab — 45+ of them, with over a decade of combined delivery experience, delivering for clients in 15+ countries. Nothing is subcontracted. You own the code, the modules and the instance from day one, whether it's hosted on Odoo.sh or your own infrastructure.

Yes, and we start the same way regardless of who built it: an audit of the configuration, the installed modules and any core file modifications, so we know exactly what we're inheriting before touching anything. Where core files were edited directly, that gets flagged early because it affects both the risk and the cost of any future upgrade.
