The short version
- Reseller agency: runs your marketing, then resells third-party tools (HubSpot, Podium, AgencyAnalytics) or sends you to buy them yourself. You pay the markup or juggle the subscriptions.
- In-house agency: runs the same marketing and builds its own software (Chat, Reviews, Reports, Voice, Inbox). They come with the retainer, not as a separate bill.
- Same channels, same media spend. The difference is who built your tools and how you pay for them.
