![Flapen cover for Cost to switch Amazon agency and expected ROI: a Flapen operator showing a client a sales chart beside an open proposal binder](https://flapen.com/_vercel/image?url=%2Fimages%2Fblog%2Fclusters%2Fhiring-an-agency-04.jpg&w=1536&q=100) Budget one month of double fees for the overlap, plus four to eight weeks of reduced momentumwhile a new team diagnoses and ad learning recalibrates. Against that, the cost of stayingcompounds. If cost of customer acquisition has drifted for two quarters, staying is almostalways the more expensive choice. ## The short version - **One-time cost:** two weeks of double fees plus four to eight weeks of softer performance. - **Ongoing cost of staying:** compounding, and usually larger. - **Quantify it** with your own acquisition cost trend rather than by feel. - **Payback usually lands in month three to four** when the switch was warranted. - **Do not switch on one bad quarter.** Switch on a bad diagnosis. ## Building the actual number I run Flapen with 50 operators managing about 70 brands, and clients arrive fromother agencies regularly. This is the arithmetic I would run before deciding. | Cost line | Typical size | Notes |
| --- | --- | --- | | Overlap fees | Two weeks of both fees | Worth paying. Buys knowledge transfer | | Your time | 10 to 20 hours | Collection, selection, onboarding | | Reduced performance | 4 to 8 weeks, partial | Ad learning and diagnosis period | | Rebuilt creative | Sometimes zero | Only if you hold flattened exports | | Rebuilt campaign learning | Sometimes significant | If campaigns lived in their tooling | | **One-time total** | **About one to two months of fee, plus a soft quarter** |  | The two variable lines are creative and campaign learning, and both depend on decisions madewhen you hired the outgoing agency rather than on anything happening now. If you own yourSeller Central account, hold source files, and campaigns were built in your own account, bothlines are close to zero. ## The cost of staying, which nobody quantifies Take your cost of customer acquisition twelve months ago and today, at comparable volume. If it has risen 20 percent and nobody has explained why, that gap is your monthly cost ofstaying, and it compounds. On a brand spending $10,000 a month on acquisition, a 20 percentdrift is $2,000 every month, indefinitely, against a one-time switching cost of about oneto two months of fee. That comparison is why sellers on month-to-month terms switch decisively and sellers ontwelve-month contracts talk themselves into waiting. The transition cost is known andone-time. The staying cost is invisible and recurring, so it loses the argument despite beinglarger. ## When the ROI is not there Three cases where switching will not pay.**The problem is your product economics.** If landed cost leaves no margin or the market isbelow the about $2 million a year floor where there is enough revenue to capture profitably,no agency fixes that. Switching buys a new opinion on an unwinnable position.**You have not raised it once.** A direct conversation naming the numbers, the unshippedinitiatives, and what you need in sixty days frequently produces a reassignment or a scopechange. That costs nothing and often resolves a caseload problem.**One bad quarter with a good diagnosis.** Numbers fall for reasons nobody controls. If thecause was identified early, explained specifically, and met with a proposal, the partnershipis working even though the results are not. ## Expected payback When a switch was warranted, expect the following shape. Weeks one to two are diagnosis. Weeks three to six are execution with performance still soft.Most accounts show measurable ACoS improvement inside the first 30 days of new management,though the full picture takes longer. Payback on the one-time cost typically lands somewherein month three or four. If nothing has moved by day 90 against the baseline you recorded before giving notice, theproblem was probably not the agency. That is worth knowing too, and it is why recording thebaseline matters. ## What most agencies will not tell you The incoming agency has an incentive to make switching sound cheap, and the outgoing one hasno incentive left at all. Neither will give you the honest arithmetic, so do it yourself withyour own acquisition cost trend. The other quiet point: most of the switching cost was determined when you signed with theprevious agency. Account ownership, creative source files, and where campaigns physicallylive decide whether the transition line is near zero or painful. If you arecurrently choosing a first agency, that is the moment to make your future switch cheap. ## Related answers - [Switching Amazon agency without losing momentum](https://flapen.com/blog/switching-amazon-agency-without-losing-momentum) - [When to switch Amazon agency](https://flapen.com/blog/when-to-switch-amazon-agency) - [Amazon agency transition timeline and risks](https://flapen.com/blog/amazon-agency-transition-timeline-and-risks) - [Month-to-month vs annual Amazon contracts](https://flapen.com/blog/month-to-month-vs-annual-amazon-contracts) - [Hiring an Amazon agency: the complete guide](https://flapen.com/blog/hiring-an-agency) Our terms are built so leaving is cheap.
