How eTIMS works with Odoo
Odoo is a popular ERP, and Kenyan businesses running it need its invoices to be compliant KRA eTIMS invoices, not just internal documents. That means connecting Odoo to eTIMS so each invoice it produces is transmitted to KRA and carries the control number and signature that make it valid.
In practice this is done through KRA's system-integration approach, usually one of the control units, OSCU (Online Sales Control Unit) or VSCU (Virtual Sales Control Unit), or through a certified integration or middleware that bridges Odoo and eTIMS. The right route depends on your Odoo version, whether you self-host, and KRA's current requirements, so confirm the supported approach against KRA's official documentation and any certified Odoo connector before committing.
The cheapest eTIMS integration is often the one you do not have to build, certify and maintain yourself.
How to approach it
A practical path. Confirm exact technical details against KRA's official documentation.
- 1
Confirm your Odoo setup and version
Identify your Odoo version and hosting, since these shape which integration approach and connectors are available to you.
- 2
Choose the integration route
Decide between a control unit approach (OSCU or VSCU), a certified connector, or middleware, based on KRA's current requirements and what fits your stack.
- 3
Map Odoo data to eTIMS fields
Ensure Odoo's products carry the correct tax treatment and that customer PINs are captured, so transmitted invoices validate.
- 4
Test in a sandbox before go-live
Validate the integration against KRA's testing environment, confirm invoices transmit and validate, then go live.
What to check before you build
Assuming Odoo is eTIMS-ready out of the box
Standard Odoo is not Kenya-specific. Confirm the eTIMS connection approach rather than assuming invoices are already compliant.
Skipping sandbox testing
Test against KRA's environment before go-live so validation and transmission issues surface safely, not on real sales.
Underestimating maintenance
A custom integration needs maintaining as KRA's requirements change. Factor that cost against using compliant software.
A distributor connects Odoo
A distributor in Nairobi ran Odoo for inventory and accounting but issued eTIMS invoices separately, so the two never reconciled cleanly.
They scoped the eTIMS connection, mapped their Odoo products to the correct tax treatment, captured customer PINs, and tested against KRA's environment before going live.
With Odoo invoices transmitting to eTIMS, sales, stock and compliance finally lived in one place and reconciled. Where the build cost outweighed the benefit, others in their network chose compliant software instead.
Trading without eTIMS-compliant tax invoices risks KRA penalties, blocked VAT input claims for your customers, and receipts a business buyer cannot expense.
Veira signs every sale to KRA eTIMS automatically, so each receipt is compliant the moment it prints, with no separate device to reconcile.
When you can skip the integration
The biggest decision here is whether you need to build an integration at all. Veira is already a compliant eTIMS system: it issues compliant KRA invoices automatically, applies the right tax treatment, captures the buyer PIN, transmits to KRA, and works offline. For many businesses that removes the need to build, certify and maintain a custom integration yourself.
If you do run an ERP or a custom stack, weigh the cost of building and maintaining an integration against running point of sale and invoicing on Veira and reconciling. Veira runs from KES 2,999 a month with a free terminal and a 30-day money-back guarantee. See how Veira works, or book a free demo to talk through your setup.

How do I integrate Odoo with eTIMS?
Is there a ready-made Odoo eTIMS connector?

Where is the authoritative eTIMS technical spec?
eTIMS Odoo integration comes down to the concepts above plus KRA's official documentation for the exact details, and for many businesses the simplest path is compliant software that handles it for you. See how Veira works, or book a free demo. Always build against KRA's current official eTIMS documentation.
