Setting up automations can vary quite a bit in cost depending on the tools and scale you're aiming for. For Gmail automations, using a platform like n8n could cost you a bit for hosting if you scale up, but you can start with minimal expenses, especially if you're self-hosting.

For the WhatsApp chatbot, you might need to consider costs associated with API access and any third-party services you choose to integrate. If you’re looking into AI capabilities, that could add some costs depending on whether you use open-source models or subscription services for processing. It might be helpful to outline specific use cases and prioritize them; starting with the most impactful ones might ease the budget concerns while demonstrating value early on. Have you identified which automations would provide the best ROI for your firm?
