Voice is where most businesses start because the leak is loudest there, but it is one surface out of six. This page maps all of them — voice, chat, sales, operations, knowledge, content — and says plainly which one to build first based on where your business is actually losing time or money.
Count what you lose. If calls ring out after five, build voice. If leads sit unworked for hours, build sales follow-up. If your team answers the same internal question forty times a week, build knowledge. Building the surface that is fashionable rather than the one that leaks is the most common way a pilot ends up with no measurable result.
Each surface shares the same knowledge base, so the second agent costs materially less than the first and the third is cheaper again. That is the actual argument for a canvas rather than a point tool: the expensive artifact is your business's structured knowledge, and every additional agent amortises it.
