Most freelancers have been there: one client is responsible for 60, 70, or 80 per cent of their income. It feels stable — until that client changes direction, cuts the budget, or brings the work in-house. The goal isn’t to avoid long-term client relationships; it’s to make sure no single one can sink you if it ends.
Know your number
A common rule of thumb: no single client should account for more than 30–40 per cent of your annual income. That doesn’t mean you can’t take on a big retainer — it means you should be actively building other revenue alongside it, not treating the big retainer as a reason to stop looking for work.
Keep your pipeline active, even when you’re busy
The feast-and-famine cycle is almost always caused by the same thing: when you’re busy with client work, you stop doing business development. Then work ends and you have to start from scratch. Set aside a minimum of a few hours a week for staying visible and maintaining relationships, regardless of how full your schedule is.
Diversify by type, not just by client
A mix of retainer and project clients is more resilient than five retainer clients, because retainers tend to end at similar times (financial year, budget cuts) and for similar reasons. Having some project-based income alongside retainers means short-term work can fill gaps when longer-term relationships pause.
Build passive or semi-passive income
Templates, courses, guides, or other productised offerings can generate income that isn’t directly tied to your time. Even a modest amount — enough to cover a few days of expenses a month — reduces pressure during slow periods and gives you more flexibility to be selective about client work.
