IT can be a profitable business, especially if you are good at what you do an build up a strong reputation in the field. If this is a strong point for you, why not offer IT services to your customers as an added extra? This is a good upsell for digital and technology businesses, and it will offer real value to your customers as well.
You can gauge interest by asking your customers how they currently conduct their IT affairs and asking if this is something they would use. You can then go on to put together a package that will work for your customers, including some flexibility for the services they want and will use.
If you use a good IT company, you can also white label services, taking on the responsibility of the service for your customer but adding on your price. This is efficient for the customer because you take care of it, and you make money as well.
