The interconnected Customer Management feature between WHMCS and Lexoffice guarantees that any alterations made to a customer’s profile in WHMCS are promptly synchronized with their corresponding details in Lexoffice. This real-time synchronization streamlines data consistency across both platforms, automating the process and alleviating the burden of manual updates, thereby ensuring accurate and up-to-date customer information management.
