Pdf creation from odoo checkout
Hannan delivered great work. Clear communication, timely delivery and the solution was exactly what we needed. We decided to move from odoo online to odoo sh in order to have a well integrated solution. Hannan identified this preferred option from the very beginning. This required some extra steps that were well guided by Hannan and included in the fixed price we agreed upon at the beginning.
The communication was clear and to the point. Hannan could be reached easily. Options and choices were clearly layed out and allowed me to make informed decisions on domains were I lack technical expertise. Big steps in the project were well elaborated in advance and shared via documents. I was involved to perform the quality checks before implementing any step.
I highly recommend Hannan.

Odoo Sales Module Customization
Great experience working with this freelancer. The Odoo customization was completed exactly as requested — the new field was added properly in the Sales app and reports. Communication was smooth, and delivery was fast. I’ll definitely consider hiring again for more Odoo work.
