It is possible to work with CRM consultants on one-time projects as well as longer-term engagements; however, the ROI (return on investment) may vary depending on the type of project. Shorter projects produce results quicker than long-term projects but may not yield the same significant returns over time. More extended engagement periods allow for more comprehensive strategies to be implemented, which could result in higher ROI by maintaining the CRM to cater to the updates in the industry and your customers.
