# When to hire a B2B marketing agency
> A B2B marketing agency is a hired team that runs some of the work: demand, content, paid, brand, or a mix. Hire when you have a brief, a budget, and an internal owner. Do not hire to rent a strategy you have not chosen.

## Hire for capacity or a craft you lack

Agencies make sense when you need paid search operators, designers, or a content engine and you cannot hire that skill this quarter. They also make sense for a bounded launch. They make less sense as a substitute for an ICP. If you cannot tell them who you sell to, they will invent a generic B2B voice and you will pay for it monthly. The [4A's](https://www.aaaa.org) is the U.S. trade body for agencies; useful for how the industry talks about scopes, not as a vendor picker.

*Hire for a motion you will not staff. Keep the offer.*

## The brief is the product you buy against

Write ICP, offer, what success looks like in pipeline terms, brand constraints, and what you will still do in-house. Include examples of work you like and work you reject. A two-page brief beats a 40-page RFP that never states the motion. If the agency has to discover your customer in week six, you bought research you could have done with five sales calls.

## Retainers, and what they quietly include

A retainer buys a block of time and a team mix. Ask who actually does the work (seniors in the pitch, juniors in the file), how many revision rounds, and what happens when a campaign needs extra production. Scope creep is usually a brief problem. If every request is "out of scope," the retainer was priced for maintenance and you are asking for invention.

## Renew, resize, or stop

Quarterly: did they hit the operating metrics in the brief, and is sales using the work? If not, a smaller project or an in-house hire may be cheaper than another year. Ending an agency is a normal business decision. Ghosting invoices is not a strategy.

## Common questions

**Can an agency own our pipeline number?**

They can own leading work (campaigns shipped, qualified meetings in a channel they run) if you give them the list, the CRM access, and a sales SLA. They cannot honestly own closed revenue if your sales team discounts or your product slips. Write the boundary in the contract.

**Should the agency replace our marketer?**

No. Someone internal must own the brief, brand voice, and vendor management. An agency with no client counterpart will either stall or quietly run the company narrative, which you may not want.
