The best time to implement n8n in your business is when repetitive tasks consume too much time and lead to errors, and you want your different tools to work together automatically.
For example, a small online store can use n8n to automatically record every new order it receives by email into its sales system, without manual input.
If your processes are simple and involve few interactions between apps, using n8n might not be worth the setup time.
