Frequently Asked Questions

Will the alert prevent posting of the bill or just raise a warning?

By default, the module raises a validation alert in Odoo 18. Contact us if you want to have a hard blocking that prevents bill posting till the price correction.

What if I have a vendor that constantly changes prices?

Use a higher tolerance percentage in this case. Module's per-setting tolerance allows you to configure an acceptable range of deviations. Use wider threshold to avoid unnecessary warnings for planned price changes.

What if I don't have a purchase order as a bill reference?

It doesn't work in this situation — the validation is performed only in case if the bill line has a reference to the purchase order line.

Is it compatible with Odoo Community Edition?

Yes — compatible with Odoo 18.0 Community and Enterprise editions on Odoo.sh and On-Premise. Requires Purchase and Invoicing modules. Not available for Odoo Online (SaaS).
