Why retainers beat projects, and why no client should be more than a quarter of the business.
A few clients, mostly projects, priced by the hour or the job. The point of this year is a portfolio, three testimonials and the knowledge of how long things really take, so write down every hour, billed or not.
The same clients, on a monthly retainer for the ongoing work: updates, content, ads, support. Retainers smooth cash flow and let you plan the month; projects stay, as the top-up rather than the floor.
The first hire or the first steady subcontractor. Your job changes from doing the work to selling, scoping and checking it, and gross margin, what's left after the people who deliver, becomes the number that says whether growth is worth it.
Agencies known for one thing, one industry or one channel, win bigger clients at better rates and are worth more to a buyer. Recurring revenue, written processes and no single dominant client are what turn an agency from a job into an asset.
| Revenue stream | Pays | Scales |
|---|---|---|
| Monthly retainer The backbone. Predictable revenue you can staff against, as long as the scope is written down. | Steady | Good |
| Project work Websites, campaigns, launches. Price by the job, take a deposit, and treat it as the way new clients start. | High, lumpy | Medium |
| Maintenance & support Hosting, updates, small changes. Little effort once it's set up, and the stickiest revenue you have. | Small each, recurring | Excellent |
| Productised service One defined package at one price: an audit, a launch kit, a monthly report. Easy to sell, easy to deliver, easy to hand to a team. | Medium | Excellent |
| White-label work Work for other agencies under their name. It fills quiet months; never let it become most of the book. | Lower margin | Good |
| Training & workshops Teaching a client's team what you do. Good margin, and it often leads to the retainer. | High per day | Medium |
| Referral & partner fees Software and platform partners pay for the clients you bring them. Tell the client. | Small | Good |
Whether the people who work for you are contractors or employees depends on how the work is done, not on what the contract calls them: the Department of Labor applies an economic-reality test, and many states, California among them, use a stricter ABC test. From 2026 a Form 1099-NEC is due only for a contractor paid $2,000 or more in the year, up from $600, but the income is reportable either way. Write down who owns the work product, and any code or templates you reuse, before the job starts. A marketing agency carries its client's risk too: the FTC's rule against fake reviews and testimonials has allowed civil penalties of more than $50,000 a violation since October 21, 2024, and the agency that writes or buys them is in the frame. Professional liability (E&O) insurance is worth having from the first client. This is general information, not legal or tax advice.
