Why MercStack
Built for companies with a warehouse, not just a website
Most shop systems stop at the checkout. MercStack follows every order through stock, delivery and your books.
Consumers and trade customers together
Retail customers buy at gross prices. Approved trade customers get net prices, their own terms, offers and ordering on account.
Connected to your back office
Orders, deliveries, refunds and returns run through one process across all your warehouses — with invoicing by MercStack or in the accounting program you already use.

Selling across borders
Any market, any language
Each market gets its own VAT and its shipping zone with prices and a free-shipping threshold, while products, stock and customers stay in one place. A new market is a setup step, not a project.
Your shop in any major European language, each with its own web addresses and customer e-mails. AI translates your products and pages, and you approve the result.
AI catalogue enrichment
AI that completes your catalogue
Most product data arrives as a code and a short name. MercStack turns it into a product your customers can find and understand — in every language you sell in.
- Categories suggested for each product, with a confidence score.
- Missing descriptions written from the product data and sources you provide.
- Translations for every market — products and pages, kept in sync.
- You stay in control: uncertain suggestions wait in a review queue, and your team's edits are protected.

Illustrative example
Back office
Keep your accounting. We run the shop.
Your books stay where they are. The shop handles orders, payments, stock and shipping — and you choose who issues the invoices.
- Option 1 — invoicing by MercStack: invoices, delivery notes and credit notes for every order, with advances and amounts exact to the cent.
- Option 2 — your own accounting program: orders are handed over for invoicing there. A direct connection to your accounting system can be finalized after reviewing its capabilities.
- Either way: orders, deliveries, refunds and returns run through one process across all your warehouses, and every payment is recorded once.

What you get
Everything a growing shop needs, already connected
From the first offer to the last refund, every step of an order happens in one place.
Sell
Consumers and trade buyers in one shop.
Trade accounts that save time
Agreed prices, saved lists and buying on account within a credit limit.
Fast ordering for trade buyers
Order by item code or product name with suggestions as you type, by CSV file or pasted list — also on a phone.
Sell under your own brand
Your domain, design and logo. Sell chosen products or whole ranges under your house brand, and pick the brands you feature.
Orders & money
From the first offer to the last refund, in one process.
From offer to invoice
Offers with cost and margin in view, discount per line or in total; the customer accepts in their account.
Orders from your shop and your team
Web orders and orders entered in the admin run through one process, each showing where it came from.
Orders you can still correct
Change quantity, price or discount until the order is invoiced, even after shipping. Amounts stay exact to the cent.
Invoicing on your terms
Invoice automatically at shipment or with one click. Payments before shipment are recorded as advances.
Payments that don't lose orders
Card payment inside your shop, retry after a failed payment, secure payment links, bank transfer, cash on delivery and payment on account.
Refunds and returns done right
Refund by items or by amount. Card payments go back to the card; you decide per item whether goods return to stock.
Stock & purchasing
Real stock, shown the way you sell.
Stock across all your warehouses
Several warehouses and goods receipts in one view; customers can ask to be told when an item is back.
Stock shown the way you sell
Show the full stock until shipment, or only what is still free. Your team sees physical, reserved and free stock and the orders holding it.
Margins under control
Receipt calculation spreads extra costs and sets prices from your markup; discounts cannot go below a recorded purchase cost.
Your processes, configured — not programmed
Stock timing, what the shop shows, when invoices are issued, which brands you feature: set per shop. Updates keep working for everyone.

Questions
Good to know
Do we have to change our accounting program?
No. MercStack can issue your invoices, delivery notes and credit notes — or hand each order over for invoicing in the accounting program you already use. A direct connection to your accounting system can be finalized after reviewing its capabilities.
Can we keep our current products and customers?
Yes. Moving your products, customers, stock and past orders from your current shop is available as a migration service, scoped with you for your current system.
Which languages and markets are possible?
Any major European language, each with its own web addresses and customer e-mails. Each market gets its own VAT and shipping zone; a new market is a setup step, not a project.
Does AI change our product data on its own?
AI makes suggestions. Uncertain ones wait for your approval in a review queue, and edits made by your team are protected.
Where is our data hosted?
On servers in the EU. Your data stays yours.
