In-house marketing vs agency — the real math for SMBs.
Hiring a marketing manager feels like control. For most SMBs under $50k/month in total marketing spend, the fully loaded cost of a good in-house hire exceeds a senior-led agency — with worse channel coverage.
| Dimension | In-house hire | Agency partner |
|---|---|---|
| Fully loaded cost (US/UK) | $65k–$110k/year salary plus benefits, tools, and training — one generalist. | $3k–$8k/month retainer covers senior strategy across Google, Meta, SEO, and web. |
| Channel depth | One person cannot stay current on Google Ads, Meta CAPI, technical SEO, and CRO simultaneously. | Team specialists with cross-account pattern recognition from dozens of SMB accounts. |
| Speed to fix tracking | 3–6 months to hire, onboard, and audit — ad spend keeps leaking meanwhile. | 24-hour audit turnaround; tracking rebuilds in weeks not quarters. |
| Accountability | Hard to fire quickly; political cost if they are underperforming. | Contract terms align to results; easier to change if fit is wrong. |
| Best fit | Companies with $100k+ annual marketing budget needing daily brand voice and internal coordination. | Owner-led SMBs who need performance channels managed by seniors without building a department. |
When in-house wins
In-house makes sense when marketing is core to the product (content businesses, large e-commerce) or when spend exceeds what any agency team can justify on a percentage fee. For the typical service SMB, a marketing manager becomes an expensive project coordinator who still outsources Google Ads.
Hybrid works: in-house for brand and email, agency for paid and SEO. We are comfortable being the performance layer while your hire owns comms — as long as tracking is single-source.
