Key takeaways
- Connect every marketplace and store to one panel so stock, orders and delivery logs live in one place.
- One shared stock pool means a sale on one channel updates availability on every other channel.
- Paid orders deliver automatically, instantly on Pro, so nights and weekends need no staff.
- Automatic repricing above your floor is dependable on G2A; on other channels you set prices yourself.
- You pay per dispatch with credits, with no subscription, so costs follow sales.
You run five marketplaces from one place by giving them one stock pool, one delivery engine and one log. Connect G2A, Kinguin, Eneba, eBay and your own store to Keysender, put your keys, codes and licences into shared inventories, and link each marketplace offer to the inventory it sells from. A sale anywhere updates stock everywhere, and every paid order delivers without you.
That is the short answer. The rest of this guide is for the seller who already has the volume: about 20,000 offers, five channels and nobody spare to watch them at night.
What changes when you sell on five marketplaces instead of one?
On one marketplace, the native dashboard is enough. You list, you sell, you deliver, you read your rating. On five, the work does not grow by five. It multiplies, because the channels cannot see each other.
- Every marketplace keeps its own stock number. Keep five numbers by hand and one of them is always wrong.
- Every marketplace has its own order queue. Orders arrive at all hours, in five places.
- Every marketplace rewards fast handling. A slow delivery on one channel costs you rating on that channel.
- Every marketplace has its own fees and price war. The same key earns a different amount on each.
An example from a normal week
Picture a seller with 20,000 offers. On Monday a new batch of a popular game arrives. Someone adds the stock to G2A and Kinguin but forgets Eneba. On Tuesday night the game sells out on Kinguin while G2A still shows stock, and three G2A buyers pay for codes that are gone. On Wednesday morning the team cancels orders, answers angry buyers and watches the rating dip. Nothing here is unusual. It is what five separate stock counts do at volume.
The fix is not more people watching more tabs. It is moving the shared work, stock and delivery, into one layer that sits under all five channels. The marketplaces keep doing what they do well: listings, payments, buyers. Our guide to G2A, Kinguin, Eneba and Gamivo seller tools maps where each native dashboard stops.
Which marketplaces and stores can one panel run?
Keysender connects to the key marketplaces, the general marketplaces and the store platforms most digital sellers use. You can run all of them from the same account.
| Type | Channels |
|---|---|
| Key marketplaces | G2A, Kinguin, Eneba, Gamivo, K4G |
| General marketplaces | eBay, Allegro, Mercado Libre, Hood.de |
| Your own store | Shopify, WooCommerce, BigCommerce, Ecwid, PayPal Buttons |
Integrations are unlimited on every plan, so adding a sixth channel later costs nothing extra to connect. You pay when you deliver.
Which channel should you connect first?
Start with the one that sells most. It gives you the most real orders to check the setup against, and it is where a mistake would hurt most, so you want it watched closely in the first days. Add the second biggest next, linked to the same inventories. Once two channels share stock without trouble, the rest follow the same pattern.
How do you keep 20,000 offers on one stock pool?
Think in inventories, not in offers. An inventory holds the codes for one product. Each marketplace offer for that product links to the same inventory. Your G2A offer, your Kinguin offer, your Eneba offer and your Shopify product for the same game all draw from one place.
When a code sells on any of them, Keysender updates availability on the others. That is what helps prevent overselling: there is one count, and every channel reads it. Each integration account also has its own sync stock switch, so you decide which accounts follow the pool. The full method is in our pillar on one stock pool across eBay, G2A, Kinguin, Eneba and your own store.
At 20,000 offers you will not type codes in. Bulk import takes a CSV or XLSX file with columns for the code, the unit cost, the currency and the supplier, checks for duplicates and reports any error row by row. Our guide to moving 20,000 offers to Keysender in bulk walks through the order to do it in.
Who delivers the order when nobody is awake?
Keysender does. The moment a marketplace confirms payment, the buyer gets the key, code, licence or file, and the order is marked shipped on the channel it came from. This runs around the clock, so an order placed at 3 a.m. is delivered at 3 a.m.
Speed depends on the plan. Pro delivers instantly. The free Starter plan dispatches within 5.5 hours, which suits testing but not a marketplace that ranks on handling time. Every dispatch is logged with a timestamp, and a resend or reissue is one click. The details are in our pillar on delivering marketplace orders with no one in the loop.
How should pricing work across five channels?
Be honest with yourself about where automation helps. On G2A, Keysender reprices automatically, above the floor you set. You type the lowest price you will accept for each offer, and Keysender follows the market without going under it. This is where repricing is dependable today.
On Kinguin, Eneba, eBay and your own store, plan to set prices and floors yourself, channel by channel, while Keysender keeps stock in sync and delivers. Work out each floor from what you paid for the stock and that channel's fees, so a low price on one marketplace still makes sense for you. Review those prices on a fixed day each week, starting with your top sellers, because a price that was right last month can be far off the market today. Our pillar on automatic repricing on G2A covers how to set floors you can live with.
What records do you need when a buyer disputes an order?
Five channels means five dispute processes, but the evidence is the same: what was sent, when, and to whom. Keysender keeps a timestamped dispatch log for every order on every channel, on every plan. When a buyer says a key never arrived, you look it up in one place instead of five.
On Pro you can also turn on fraud screening. It is opt-in, each check uses 1 credit, and on eBay and Shopify you can set thresholds per listing. Blacklists and whitelists, with wildcard and regex matching, let you stop known bad buyers on any channel. Our chargeback and fraud playbook covers the review workflow.
What does it cost to run five channels this way?
Keysender is paid per dispatch with credits. One credit covers one delivery. Every account starts with 20 free credits. Pro starts as low as 6 cents per dispatch, credits do not expire, and there is no subscription or minimum. Inventory sync, custom SMTP, a custom access page and dispatch logs are included on every plan.
Fraud screening on Pro is the one extra cost, and only if you turn it on: each check uses 1 credit.
That model matters at scale. A slow month costs almost nothing, and a busy one costs in line with what you sold. If you run thousands of orders, your rate depends on volume: see pricing, or step through the demo, then ask the team for your rate.
A five-channel setup checklist
- Connect each marketplace and store under Integrations.
- Create one inventory per product and import codes in bulk.
- Link every marketplace offer to its inventory.
- Turn on sync stock for each integration account that should follow the pool.
- Set floors on G2A and prices on every other channel.
- Switch to Pro for instant delivery, and decide whether to turn on fraud screening.
- Check the dispatch log after the first night of orders.
Start with the two channels that sell most, prove the setup on real orders, then add the rest. Keep notes on anything you change during the first week, so you know which change fixed which problem. The game keys multi-marketplace playbook covers where each marketplace fits.
