SellerHQ presents itself on its website as a full-service marketplace agency for Amazon and Bol.com, running Seller Central management through a three-part process. Flapen employs 50 operators, launches brands from zero, and publishes the outcome it holds itself to. Six written questions, listed below, separate the two models.
The short version
- SellerHQ states a full-service scope. Its website names Seller Central management, Marketplace PPC, SEO, Design, and Platform Management.
- SellerHQ publishes a three-part process. The stages are introduction, optimization, and results, in that order.
- SellerHQ publishes no fee on the captured pages. Its contact page invites a strategy session instead.
- Flapen publishes the outcome it holds itself to. The majority of the brands we run reach profitability within their first year.
- Flapen sources, launches, then runs the brand. Guangzhou sourcing, Dubai creative, 50 operators, nothing subcontracted.
What SellerHQ says it offers
This section comes from two pages on sellerhq.nl captured on 5 September 2026, and the site is in Dutch. The home page is titled as the marketplace agency for Amazon and Bol, and its headline reads grow and win on marketplaces. Its meta description calls SellerHQ your full-service marketplace agency for Amazon and Bol.com.
Seven creative headings run in this order: Listing Images, A+ Content, Storefront Design and Brand Story, and Photography and Rendering. The last three are Branding and Packaging Design, Seo Copywriting, and Product video. Four service headings sit on that page: Marketplace PPC, SEO, Design, and Platform Management.
The words 25% Growth appear three times as a heading band, with no account or period beside them. One sentence states that as a full-service marketplace agency it takes the whole Seller Central management off your hands. That scope includes the parts it says other agencies often skip.
Another sentence runs from profitable PPC campaigns and strong SEO to product images and a complex catalog on Amazon, Bol, and other platforms. The process is stated stage by stage. Introduction names setting expectations, onboarding, kick off, competitor analysis, and an account audit.
Optimization names continuity, catalog, advertising, SEO, and design, and results names tracking growth, traffic, conversion, sales, and A/B testing. A section on full-service management of your marketplace account lists seven items. They are product listings, A+ Content, inventory management, forecasting, pricing, compliance, and account management.
A separate heading states that a fixed team grows with you. A case study heading states a move from loss-making to more than 25% margin on Bol.com within two months.
The contact page invites a strategy session, and a form asks what you are interested in. The options it lists include A+ content, Photography, Brand Story, Storefront, and Website Design. No fee, no partner badge, and no founding year appears on either page as of September 2026.
What Flapen offers
On the day you leave, the Seller Central account is still yours. So are the campaigns we built, the creative we shot, and a written handover. Notice is 30 days, month to month, with no long-term contract and no lock-in.
We work inside your own account on permissions you grant and revoke, and deliverables become your intellectual property on full payment. That is what Amazon brand management means here.
Fifty operators carry about 70 brands between them, all on our payroll, with sourcing in our Guangzhou studio and creative in Dubai. Every tier carries all 50+ services, from $800 a month for one product to $2,400 for five, no commission and no onboarding fee.
Our system runs five steps: market, product, traffic, plan, launch. A market clears $2M a year and returns under 8% before we quote it, and Phase 1 puts 200 units live on $5K to $10K. Our science publishes 193,753 niches scored at the 2026-08-26 capture, with 4.8% passing.
Our operators work in tools we built for ads, marketing, and valuation, on the data layer our platform serves to 15,000 sellers a month.

Where SellerHQ may be the right fit
Fit is not quality, and this is about fit alone. One heading asks why brands in the Netherlands choose SellerHQ, so a Dutch-speaking seller is addressed in their own language.
It names Amazon and Bol.com together. Its captured pages describe a launch on Amazon Germany and Amazon France, with optimized listings and growth in international sales.
A brand we launched and run
Every store on flapen.com/results was built and launched through Flapen's Amazon FBA service. GrillX runs on our Full Account Management membership, with listings, inventory and reporting handled by one team. The headline figure is ACoS 88% to 32%.
The outcome sentence reads: The worst-performing ad line rebuilt into a keeper, while sea freight negotiated to $1.04/kg kept the landed cost honest.
How to test both of us
If your position is my product is live but sales are not where they should be, this list is for you. Send it in writing to every company on your shortlist, mine included.
| # | Ask this in writing | Done properly looks like |
|---|---|---|
| 1 | What outcome do you hold yourselves to? | A result repeated in public. Ours is the majority of brands profitable in their first year |
| 2 | How many brands you took on last year are profitable today? | A count, a date, and the ones that are not |
| 3 | Which account and period sit behind a figure on your site? | One account, one date range, one starting number |
| 4 | What would make you tell me to stop selling a product? | The four signals, read over 60 to 90 days |
| 5 | Who does the work, and where? | Employed roles, named cities, subcontractors named |
| 6 | What do I keep the day I leave, on what notice? | Account, campaigns, creative, handover, notice in days |
Score each answer done or not done. If Flapen does not clear your version of this list, do not hire us.
What most agencies will not tell you
A comparison page by one agency about another proves nothing, so weigh the list, not my adjectives. These four items are the ones sellers skip.
- Profitability carries a date or it carries nothing. Done properly, the answer names the month a brand covered its costs and the ones that never did.
- A published percentage needs an account behind it. Done properly, the figure arrives with its account, date range, and starting number.
- Your share of attention moves when the next ten clients sign. Done properly, the agency states how many brands your manager carries and where that goes next.
- Exit terms belong in writing before you sign. Done properly, the notice period, the account, the campaigns, and the creative are named in the agreement.
SellerHQ alternatives
Four shapes exist here, and the shape matters more than the name on the invoice. Full service hands one team the whole account for a monthly fee. A specialist takes a single function, most often advertising.
An in-house hire puts the knowledge on your payroll. A platform sells data and leaves the doing with you.
