What's your strategy to avoid future work from such clients? I've thought the contract should include creating documentation for maintenance (e.g. login details to various services to update payment information or software versions or whatever) that the business can keep secured and that while you can be reached to perform certain kinds of maintenance at some fee you aren't obligated to. I had a friend in freelancing who self-hosted everyone on his own servers and charged an ongoing fee, though if I were a client I'd be nervous if the freelancer decided to raise their fee for the understandable reason that maintenance costs can increase.
