I am working with a number of small clients that often request small changes, once every 2-4 months at least, and the constant task-switching of working 1 hour for this client and 2 hours for that client is not ideal. Invoicing and sometimes needing to follow up on late payments doesn't help either. There's more time wasted than I care for, and the late payments are especially infuriating.
To combat this, I am thinking of moving away from hourly work and offering mainly prepaid packages of hours. It could be a 5 hour, a 10 hour, and a 20 hour package plan. By buying in bulk, there would be a small discount, and bigger discount with more hours. When a package is paid for, it could be valid for let's say 3 months.
I would sell this new way by mentioning the discount, higher quality of work, and priority service. I would also raise my hourly rate at the same time, making the packages seem a better deal.
After a package has been bought, I would keep the client updated on how many hours have been worked after each task.
If these small clients had more work to do, I would definitely try offering a day rate, but that may be too much for these clients.
Has anyone done this or is doing this? Any advice or potential issues that could come up?
