Managing one client's catalog is already work. Managing ten is a whole different league: ten stores, ten supplier formats, ten brand voices, ten taxonomies that look nothing alike. If every client starts from scratch and ties up one person, the agency doesn't grow: it drowns. The question isn't "how do I build a catalog?" but "how do I build ten without cloning the chaos ten times?"
The agency problem: multiplying without cloning the chaos
Every new client brings their own world: their store and its credentials, their suppliers and their impossible CSVs, their way of talking, their categories. The mistake is treating each one as a separate, handcrafted project. It works with two clients; with ten, you spend your days switching contexts and putting out fires.
One isolated account per client
The first principle: each client has their own account, with their catalog, their store, their voice and their approvals, and we set it up with you. One client's data never mixes with another's: each one is its own space, not one more tab in a giant spreadsheet with everything lumped together. That clean separation is what makes ten clients ten tidy folders instead of a junk drawer. The multi-client console is coming soon.
Each brand's voice, not yours
An agency that writes the same way for all ten clients does them a disservice: they all sound like the agency, none like themselves. The brand voice is defined once per client, with its examples and its limits, and applied to their whole catalog. That way, the cosmetics brand sounds like cosmetics and the hardware brand sounds like hardware, even though the same team manages both from the same tool.
Setup, once per client; the weekly work, in bulk
The trick is to separate what gets configured from the recurring work. Connecting the store, defining the voice and mapping the taxonomy are done once per client. From then on, the weekly work — importing the new CSV, enriching, reviewing, publishing — is done in batches, supervising instead of typing. The effort stops being proportional to the number of products and becomes proportional to the number of decisions.
The business model this opens up
When managing a catalog no longer eats up a whole person, the agency can take on more clients with the same team and offer ongoing catalog management as a recurring service — not just the initial setup, but keeping it correct month after month. The catalog goes from being a cost to being a predictable revenue stream.
Start with one, plan for ten
You don't need to build the perfect machine on day one. Start with one client, get their catalog in order, define their voice, automate the repetitive work. Once that client practically runs itself, the second costs less and the tenth is routine. That's how an agency goes from "I can't take on more clients" to "how many do I want to take on?"
