About this gig
Need Odoo to follow your real business process instead of forcing workarounds? I am an Odoo 19 certified developer. I build custom modules and extend standard apps without breaking future upgrades.
What I can build for you:
- New fields, views, menus, access rights and security rules
- Approval workflows, automatic checks and scheduled actions
- Sales, Purchase, Inventory and Accounting logic changes
- QWeb PDF reports: quotations, invoices, delivery slips, custom forms
- Customer and vendor portals with secure links
- API integrations: payments, SMS, GPS, currency rates, e-invoicing
- Dashboards and KPI reports
How I work:
- You describe the need, I confirm scope and price before starting
- Separate module that inherits standard Odoo, core is never edited
- Tested on a staging copy, delivered with source code and short notes
Odoo 17, 18 and 19, Community and Enterprise, Odoo.sh or on-premise. Please message me before ordering so I can check your version and give an exact quote.

FAQ
Which Odoo versions do you work with?
Mainly Odoo 17, 18 and 19, both Community and Enterprise. My daily work is on Odoo 19 Enterprise.
Will you modify the Odoo core code?
No. Every change is delivered as a separate module that inherits standard Odoo, so your future updates and upgrades stay safe.
Can you work on Odoo Online, Odoo.sh or on-premise?
Odoo.sh and on-premise: yes, with custom modules. Odoo Online does not allow custom code, so there I work with configuration and Studio only.
Do I get the source code?
Yes, always. You receive the full module source code with short installation and usage notes.
