Budget: 27000 UAH Deadline: 18 days
I would consider Whapi or Green API first. If you need a turnkey service without maintaining your own server - Whapi, if manageability and transparent webhooks are more important - Green API. Baileys makes sense only if you are ready to maintain your own microservice and take on support after WhatsApp Web updates. The fixed turnkey implementation is 120,000 UAH, with a term of 18 working days after access is provided. Similar WhatsApp connections with CRM have been made, and we have also worked with Odoo CRM.
At the implementation level, I would include a message queue, status log, retries on failures, attachment processing, matching numbers with contacts, creating a lead on the first contact, and rate limiting. A gray connection cannot be made !!without a guarantee of zero risk of banning!! - it can only reduce the risk through limits, warming up, pauses, and avoiding mass mailings =/
You will need to provide access to a test Odoo, rights to install the module, a separate WhatsApp number for testing, and a list of lead fields. It is practically important to check the version of Odoo, where it is hosted, and whether there are custom CRM modules.
> Questions
>> What version of Odoo is it and is it Odoo Online, Odoo.sh, or a self-hosted server?
>> How many managers and WhatsApp numbers need to be connected at the first stage?
