CUSTOM CRM required... I do not want to use software / app which requires me to pay a monthly subscription. I require a simple CRM developed, which must have a sales funnel, as shown in attachment. I need to be able to add clients manually or bulk upload with XML file. I need the CRM to integrate with WhatsApp, allowing me to message client easily.
Please, only reply if you have experience building a CRM of this type before. Thank you
