Launching 2027, 20 founder spots up for grabs
Orders. Inventory. Shipping. Invoices. Marketplaces.
Automated. Seamless. Scalable.
SELLUNIQ brings every order from Amazon, eBay and your shop into one place, writes the invoices and prints the shipping labels. On your computer, on your tablet and on the go.
Connects with
You decide once how things should run. From then on, SELLUNIQ handles every order the same way, whether it comes from Amazon, eBay or your own shop.
From every channel into the same list.
In your own warehouse, at your fulfillment partner or at your supplier.
Whenever you want, as XRechnung for business customers.
Right carrier, right box.
Bank, PayPal and marketplaces, automatically.
DATEV export, archived tamper-proof.
Selling
Create listings for Amazon, eBay, Kaufland, Otto and Etsy right in SELLUNIQ, without logging in to the marketplace. Sync price, description, images and stock for one product or hundreds at once.
Warehouse, fulfillment, dropshipping
Your own warehouse, Amazon FBA, a fulfillment provider or your supplier: SELLUNIQ knows the stock at every location, reserves it when an order comes in and prevents overselling. Your rules decide which warehouse ships.
Invoices and payments
Invoices, credit notes, quotes and payment reminders, numbered sequentially and locked once issued. Automatically as XRechnung or ZUGFeRD for business customers. Payments from your bank, PayPal and marketplaces are matched to invoices on their own.
Automation
You decide when the invoice is created: at purchase, on payment or on shipping. Which email goes out, which carrier and which warehouse. Set it once and it applies to every order.
SELLUNIQ runs on your computer, iPad, Android tablet and phone, with every feature. Check orders, write invoices, change prices, reply to customers, view stats: at a trade fair, at your supplier or from the sofa.
What you pay three or four tools for today is included in every SELLUNIQ plan.
Deutsche Post, DHL, DHL Express, DPD, GLS, Hermes, UPS, GO!, Amazon labels, Austrian Post, shipcloud and Sendcloud. As many box sizes as you like, SELLUNIQ picks the right one. Print labels and barcodes from your PC, tablet or phone, on almost any label printer.
Templates, pages built from blocks, edit products right in the shop.
PayPal, Klarna, credit card, Apple Pay, Mollie, GoCardless, pay by invoice.
Reminder, three escalation levels, fees, automatic or with approval.
Terms, cancellation policy and privacy policy, versioned for every order.
If you have a direct debit agreement with your bank, you don’t need a middleman: SELLUNIQ manages the mandates, submits the direct debits via EBICS or FinTS and matches payments and returned debits automatically.
REST API and webhooks for your own integrations.
Interface, documents and emails in German and English, more languages to follow.
Unlimited users, roles and permissions the way you want them, custom fields and tables that everyone sets up to suit how they work.
In Germany, every invoice to a business customer will soon have to be machine-readable. SELLUNIQ creates XRechnung and ZUGFeRD automatically, with no extra software and at no extra cost.
Highlighted items are planned for the 2027 launch. The rest follows in the months after.
The biggest worry when switching is your own data. Bring everything you need: from Billbee, JTL, Afterbuy, plentyONE, Xentral, from web shops like Shopify, WooCommerce, Shopware or Gambio, and from many other programs. If all else fails, a CSV or Excel file will do.
A CSV or Excel file is all it takes. There are ready-made templates for common programs and web shops; anything else you map once yourself.
SELLUNIQ shows you in advance what will be imported. Nothing is written until you approve.
Connect Amazon, eBay and your shop, continue your document numbering, done. We support our founders personally.
SELLUNIQ launches in German-speaking countries, but it’s built for cross-border trade. Want to expand into a new country? SELLUNIQ brings the local marketplaces, carriers, payment methods and tax rules with it.

The core features are included in every plan. Book these services only when you need them, at a fixed price you know upfront.
You stay on your plan, even in strong months. We never upgrade or downgrade you automatically. Each order above your allowance costs €0.10 on Start and €0.08 on Growth and Pro. From 750 orders a month, Growth is cheaper than Start; from around 2,500 orders, Pro is cheaper than Growth. You can switch at any time.
| Example | Invoice | You pay (excl. VAT) |
|---|---|---|
| Start, 400 orders | €29 + 150 × €0.10 | 44 € |
| Start, 1,000 orders | €29 + 750 × €0.10 = €104, with Growth only €79 (€25 cheaper) | 79 € |
| Growth, 3,000 orders | €79 + 2,000 × €0.08 = €239, with Pro only €199 (€40 cheaper) | 199 € |
| Pro, 4,000 orders | €199 + 1,000 × €0.08 | 279 € |
SELLUNIQ is for businesses only. All prices are planned net prices at launch, excluding VAT; for businesses in the EU the reverse-charge mechanism usually applies, and you account for the VAT yourself. Monthly plans can be cancelled at the end of any month; the annual plan is paid in advance and runs for twelve months. You can upgrade at any time and downgrade at the end of your term. A shop on a SELLUNIQ address is free.
SELLUNIQ wasn’t dreamed up on a drawing board. Its core has been running live since October 2026 at a German online retailer with its own shop, Amazon and eBay.
Every feature had to prove itself there in day-to-day business before it made it into SELLUNIQ: real orders, real invoices, real returns.

2027. Everyone on the waitlist gets early access to the beta and is the first to hear the launch date.
Yes, including from many other programs and web shops, for example plentyONE, Xentral, Shopify, WooCommerce, Shopware, Gambio or Magento. If all else fails, a CSV or Excel file will do. SELLUNIQ imports products, customers, stock and open orders. You can bring old invoices along as an archive, so you keep meeting your record-keeping obligations.
Yes, with every feature. SELLUNIQ runs in the browser on tablets and phones. Apps for iOS and Android with a camera scanner and notifications follow after launch.
You stay on your plan. Each order above your allowance costs €0.10 on Start and €0.08 on Growth and Pro. You can upgrade yourself at any time if it pays off for you.
No. You can connect just marketplaces, or your existing Shopify, WooCommerce or Shopware shop. The SELLUNIQ shop with your own domain costs €19 per month excl. VAT.
Yes. Manage as many warehouses as you like, including fulfillment warehouses and suppliers. SELLUNIQ uses your rules to decide which warehouse gets an order.
Yes, with Enterprise, no matter how many orders you have. At extra cost, we build custom automations and adjustments or connect your own database server that you can access directly. We discuss what’s possible with you and put it in the contract.
Almost any label printer, for example Zebra, Brother, Dymo, Godex or TSC, plus regular office printers. SELLUNIQ controls the printers directly, without drivers. Prefer to print through your driver? That works too. You decide which printer prints what: for example the delivery note in the warehouse and the shipping label at the packing station, or everything on one printer. If a printer model is missing, we’ll add it.
Yes, with the optional tax assistant. It guides you step by step through applying for a VAT ID, OSS registration and foreign tax numbers, and prepares your OSS return. Where needed, we work with tax advisors.
Yes. If you have a direct debit agreement with your bank, SELLUNIQ creates the direct debits and submits them straight to your bank. Returned debits and incoming payments are matched automatically. Alternatively, you can use GoCardless.
In data centres in Germany. Each seller sees only their own data, and this is checked automatically with every code change.
You export all data and documents in one click. Your documents stay available for the legally required retention period.
We’re raffling 20 founder spots among everyone on the waitlist: Growth for €49 instead of €79 per month excl. VAT, for 24 months. We have more planned for our founders, details to follow.
