You can miss invoices or due dates: when you’re dealing with multiple suppliers, it is very easy to miss a deadline, forget to send an invoice or forget to cash out some money. That’s because, as a business owner, you’re dealing with a lot of things. However, at the end of the day, when your cash flow is affected by the missed invoices, you won’t be able to use the “I was busy” excuse. If you’re dealing with the finances of your business, then you are accountable for whatever goes bad.
