One-off project — when there's a single, finite task
You need a logo, a website or a brand book — and once it ships, you don't need a designer again until the next big task comes up. This fits startups at launch, one-time events, a rebrand. The upside: you pay once for one deliverable and know the budget upfront.
Ongoing support — when tasks keep coming and never really stop
If a brand constantly ships content — social posts, marketplace cards, ad banners, presentations, print for events — hiring separately every time means: finding someone, explaining the task from scratch, waiting for them to get up to speed on the brand. Ongoing support removes that friction: the designer already knows the brand, already has the source files, and tasks get closed as a steady stream.
For MONIN®, for example, I've run ongoing brand support for over two years — that's produced 547 layouts across 28 categories, from marketplace cards to trade show print. If each of those had been ordered separately from different people, explaining the brand context alone would have taken multiples of the time.
How it's structured, money-wise
Ongoing support is set up as a monthly agreement with a fixed number of hours or tasks. Payment happens at the start of the month. This tends to work out cheaper than hourly freelance rates if the task volume is genuinely high: the effective hourly rate on a retainer is usually lower, and quality is more consistent because one person owns the whole visual language of the brand.
How to tell which one you need
A simple test: count how many design tasks came up over the last three months. If it's occasional — three or four tasks a quarter — one-off projects cover the need fully. If tasks arrive in a steady stream, weekly or more often, ongoing support is almost always faster and cheaper than scattered one-off orders.
