Custom automation vs SaaS, an agency, or an in-house hire
Four honest ways to solve the same problem. SellerUp is one of them — and not always the right one.
| What you are comparing | Off-the-shelf SaaS | Generalist dev agency | In-house hire | SellerUp |
|---|---|---|---|---|
| Setup time | Same day — sign up and connect an account | 2–6 months, plus time spent teaching them the marketplace | 1–3 months to hire, then months to ramp up | First working piece in weeks; full build in 2–4 months |
| Cost shape | Monthly subscription per seat or per order | Project fee, usually higher because marketplace context is billed as discovery | Salary, taxes and equipment — permanent | Project fee, then optional support; no per-seat licence |
| Fits your process | You adapt your process to the tool | Fits what you specified — marketplace edge cases usually surface late | Fits exactly, at the speed one person can build | Built around your operations; we already know the marketplace edge cases |
| Data ownership | Your data lives in the vendor’s account | Usually yours — confirm it in the contract | Yours | Yours: code and data run on your infrastructure |
| Who maintains it | The vendor — including changes you did not ask for | Usually a separate retainer | The same person, alongside their other work | We support it, or we hand it over with documentation and training |
| When it breaks down | When the last 30% of your process is the part that makes you money | When marketplace APIs and fee logic turn out to be the hard part | When that person leaves | When the task is genuinely standard — then a subscription is cheaper |
SellerUp is the wrong choice if you need a fix this week, or if an off-the-shelf tool already covers your process end to end. In those cases buy the SaaS — we will say so on the call.
FAQ: choosing a service
Which service do I need if I already sell and just want fewer manual hours?
Turnkey AI automation, and within it the agents track. We map where the hours go — listings, prices, stock, ads, reports — and automate the repetitive part first.
If the problem is that the numbers themselves are unreliable, we start with the analytics track of the same service instead: automation built on bad data automates the mistake.
Can we start small instead of committing to a full build?
Yes, and most engagements do. The usual starting point is a strategy session or a process and data audit, which ends in a written automation plan you can execute with us or without us. From there we cut the work into a first piece that lands in weeks, so you see something running before the larger commitment.
Which marketplaces do you work with?
Amazon is the core. Allegro is second, with a dedicated service line for the Polish market covering launch, analytics and training. We also build integrations for Kaufland, Castorama, Leroy Merlin, eMAG, Bol and other European platforms. If a platform publishes a usable API we can build against it; if it does not, we say so before you commit.
How long does a project take, and what does it cost?
The two fixed-price Allegro services are published: turnkey launch from $2,500 and product analytics from $900.
Engineering work is quoted per project. A first working piece usually lands in weeks and a full build in two to four months. Describe the task and we come back with a range within one business day.
Do you work with sellers outside Poland and Ukraine?
Yes. The engineering work — AI automation, custom software and analytics — is location-independent, and we work with sellers across the EU. The hands-on Allegro launch service is specific to the Polish market, with optional expansion to allegro.cz for Czechia and Slovakia. Everything else is delivered remotely.
