It’s good if you have a system in place to monitor your subscriptions. You are already one step ahead of other companies! But also your method costs much more time than it actually needs. Put your focus on automation! Because: If all costs are debited from the same card, your accounting department will need more time for the correct allocation to cost centers etc. You also have to maintain budgets manually and thus hardly get real-time insights. And last but not least, you have to rely on the employees responsible for the subscriptions to forward the incoming invoices. These must then still be manually matched with the respective transactions in the accounting department.
