We solve real pain points for marketplace sellers

Pick the situation that applies to you — we'll show exactly how Marketplace365 eliminates it.

Amazon · Most common issue

Account Health in the red. A-to-z claims. One bad week and you lose years of account work.

Amazon monitors Response Rate, Late Response Rate and Customer Dissatisfaction Rate in real time. Crossing a threshold triggers a warning. A second warning means suspension risk. A-to-z claims automatically penalise your account if you don't respond in time. There is no margin for error here.

eBay · Most common issue

Buyer Protection disputes, negative feedback, cross-border communication in 9 languages.

eBay sellers face high buyer expectations shaped by years of C2C interactions. Buyer Protection means slow or unclear communication escalates rapidly into formal disputes against your account. Selling across Germany, UK, France and Italy at the same time — without dedicated native-language agents — is a recipe for falling seller scores.

Q4 / Seasonality · Most common issue

Black Friday, Christmas — your support team won't cope with 3× normal volume.

Every order generates questions and complaints. If you rely on one person, seasonal temps or handle it yourself — your metrics will drop exactly when Amazon and eBay are watching most closely and the stakes are highest. Hiring for 6 weeks makes no sense. We are already ready.

Multi-platform · Most common issue

Amazon, eBay, ManoMano — each platform has different rules. Everything lands on one person.

Each platform has its own response rules, its own messaging panel, its own penalties for delays and its own suspension thresholds. One person cannot handle everything simultaneously — especially when one platform has a sale running and another is seeing a wave of complaints.

Business Growth · Most common issue

Your sales are growing. customer service isn't keeping up. The owner is still answering messages personally.

Hiring, training and managing support agents takes time and money you don't have. In the meantime metrics deteriorate, customers grow impatient, and you're stuck in the inbox instead of growing your business. Outsourcing is not a luxury — it's a cost calculator.

Why Marketplace365 is a different league

We stand behind the corporate infrastructure of Salesupply — and we do things no freelancer or small agency can.

Unique advantage
📞

We call the buyer before the claim destroys your ODR

A-to-z claim filed by a French buyer? Our agent calls them in French — same day. A buyer who gets a phone call in their own language withdraws the complaint. Withdrawn claim = zero impact on Account Health. Email can't do that.

🌍

Multilingual support — native

Germany, UK, France, the Netherlands, Poland — we respond in the buyer's language without translators and without delays. One partner, multiple markets, one SLA.

⚖️

Salesupply corporate infrastructure

Marketplace365 is part of Salesupply — one of Europe's largest e-commerce outsourcing operators. ISO-grade processes, contractual SLA with financial liability, professional indemnity insurance.

🔄

New platforms without a new contract

Expanding to ManoMano, Cdiscount, OTTO or Mirakl? We continuously build integrations with new marketplaces. No new vendor search — we're already ready alongside you.

How we work in practice

A real client story — data changed at the client's request.

📍 France · Amazon FR · 2024

Polish seller's Amazon account on the edge of suspension due to A-to-z claims from France

An electronics distributor from Warsaw, active on Amazon DE and FR (~8,000 orders/year). Account Health below threshold — 4 undeserved A-to-z claims escalated by French buyers, no Amazon response to emails for 3 weeks.

🔴 Problem

Account Health below 200 points

French buyers filed A-to-z claims after non-delivery (carrier fault). The client tried to resolve the issue via email for 3 weeks — without result. Account on the edge of suspension.

🟡 Action

Phone call to Amazon Seller Support in French

Within 48h of the brief, our agent called Amazon Seller Support — in French, with complete delivery dispute documentation. Each of the 4 claims escalated to the Account Health department with a full case file.

"We launched on Amazon DE without hiring a single support person."
We had board approval to expand to Germany, but no additional hires. Marketplace365 solved that paradox. Three months after signing — Amazon DE live, customer service in German, 100% SLA, one invoice. The expansion that was supposed to be impossible became our fastest-growing channel.

"Zero Amazon warnings for 14 months — even through Q4."
We had two Account Health warnings in Q3. One more and Amazon would have suspended us. Marketplace365 took over in 4 weeks. 14 months later — zero warnings, zero A-to-z claims lost, Account Health consistently green. I sleep well now.

"Q4 used to flatten us. This year we handled 3× the volume with zero SLA breaches."
Every November was a nightmare — temp workers, errors, seller scores dropping exactly when it mattered most. With Marketplace365 the peak became invisible to us. They scale seamlessly, SLA holds, seller score holds. Q4 is now our best quarter start to finish.

"One contract instead of 3 freelancers across 3 platforms."
I was managing three people on Amazon, eBay and ManoMano — different quality, different availability, constant coordination. Marketplace365 replaced all of that with one agreement. Now I have one dashboard, one invoice, one account manager. Quality improved, cost dropped, and I finally have headspace for sales.

"Expanding to France without a French speaker on the team."
We wanted to sell on Amazon FR and ManoMano but had no French-speaking staff. Marketplace365 handled buyer communication natively in French from day one. Six months in — 4.9 star seller rating, zero Buyer Protection disputes lost, sales up 60%. The language barrier simply stopped existing.

"The owner finally stopped answering messages personally."
For 3 years I personally replied to every message on eBay and Amazon. Evenings, weekends. Marketplace365 took it over in 4 weeks. Today my accounts have better metrics than ever, and in that time I focus on what drives sales — not sitting in the messaging inbox.

Everything you need to make a decision

A question not answered here? Ask it during the free audit.

How much does marketplace customer service outsourcing cost?
We offer two pricing models:

Per-ticket: You pay per message handled. Predictable cost, scales with volume. Ideal for sellers with a regular order flow.

Per-hour: You pay for dedicated agent time. Flexible — preferred by marketplace agencies managing multiple accounts.

Both models include the same guaranteed 24h SLA. During the audit we'll tell you which model fits your profile.
Which platforms do you support?
We cover all major European marketplaces: Amazon, eBay, ManoMano, Kaufland, Decathlon Marketplace, OTTO, Bol.com, Cdiscount, Allegro, Modivo, Empik and more.

We also handle messages from your own webshop (Shopify, WooCommerce, Magento) through your existing helpdesk (Zendesk, Freshdesk, Gorgias or others).
How long does implementation take?
Standard implementation — from contract signing to the first handled message — takes 3 to 4 weeks. This includes:
  • Building the knowledge base (products, policies, escalation rules)
  • Agent training and quality review
  • Platform access configuration (seller accounts, helpdesk tools)
  • SLA setup and activation of the reporting dashboard

In urgent situations (e.g. account health in the red) we offer accelerated onboarding in 10 days. Ask about this during the audit.
Is the 24h SLA genuinely guaranteed in the contract?
Yes. 100% 24h SLA is a contractual commitment — not a target, not "we try". Our standard agreement includes SLA definitions, measurement methodology and financial liability clauses for breach.

This is one of the key differences between Marketplace365 and freelancers or small agencies, where SLA guarantees are typically verbal only.
What about Q4 — does the price increase with higher volume?
No. The per-ticket model is naturally scalable — you pay for messages actually handled, without Q4 surcharges and without renegotiation when volume grows.

In the per-hour model Q4 may require a temporary increase in hours — we agree this in advance so you have time to plan. We recommend getting in touch before October, not after.
What is the minimum contract length?
The standard initial term is 12 months, then monthly rolling. That's how long it takes to build a solid knowledge base and train agents to your brand voice — typically 2–3 months to reach full quality.

For marketplace agencies managing multiple sellers we offer more flexible terms. Let's discuss during the audit.
How does reporting work?
You receive a monthly report with key metrics: message volume per platform, first response time, CSAT, SLA compliance, most frequent topics.

For clients on Zendesk, real-time reporting is available through a dashboard. The monthly report is sent by the 5th of the following month — always with a comment from your account manager.
How do you handle data security and GDPR?
We operate as a GDPR-compliant data processor. Our standard DPA (Data Processing Agreement) covers all EU data protection requirements. Agents only access the data necessary to resolve the request.

All access is logged and auditable. We can also work within your existing helpdesk environment — in that case customer data never leaves your systems.
