Looking for a Linnworks alternative?
Linnworks runs orders, listings and stock across your sales channels. If you are leaving it over order management, we are not the answer: we do none of that. If what you are missing is the buying decision, what to order, when and how much, you may not need to leave at all.
What Linnworks says it does.
Its homepage puts the pitch plainly: “One platform to run and grow every channel you sell on,” connecting inventory, orders, warehouses, listings and shipping carriers. Planning is sold separately, as a paid add-on to Linnworks Advanced. Its stock forecasting page says the add-on uses your sales velocity and supplier lead times “to tell you how much to order and when,” and adds: “It even builds the POs.” It is just as plain about who sets the targets: “You set optimal stock levels.”
For the harder inputs, Linnworks points to a partner. Its own comparison table marks seasonality and promotions as adjusted manually in the built-in tool and factored in automatically in Inventory Planner, its preferred planning integration, which it offers to roll into your existing contract. Either way, the software suggests. The levels, the lead times and the order still need an owner.
The routes Linnworks offers.
Linnworks’ own forecasting
A paid add-on to Linnworks Advanced. Its documentation says it bases next year on what you sold the previous year, adjusted by any demand profile you give it, and replenishes back to target levels you set. For accurate forecasts, every order has to run through Linnworks.

The quiet third option
Keep Linnworks for orders and skip the planning subscription. A model built once on your own catalog, in files you can open, kept true by a weekly rhythm. That is the Volumetris build. What it covers →
The add-on builds the PO. Somebody still sets the levels.
A forecast is only as good as the inputs under it, and Linnworks’ own documentation is candid about whose job those are. Any change you expect this year (growth, a new channel, a campaign) “needs to be manually inputted,” in its words. The lead time defaults to a static value on the supplier record, and the order quantity to two lead times of stock. Three ways that drifts:
A target level is a guess with a date on it
You set the level in spring. The add-on replenishes back to it, faithfully, whether demand has doubled or halved since. Nothing in the tool knows the guess has aged.
A static lead time goes stale quietly
The add-on reads the lead time from a field. The factory that slipped two weeks said so in a chat thread, not in that field, so every order date downstream is built on one that no longer exists.
Anything new is adjusted by hand
Last year’s sales carry last year’s seasons. A promotion, a launch or a peak that moves does not, and Linnworks’ own comparison marks seasonality and promotions in the built-in tool as adjusted manually. Somebody has to see it coming and change the inputs before the stock runs out.
At Coda Music a planning tool was already in place. Run beside it, our manual plan found that across 37 order lines, supplier minimums more than doubled the commitment, and nobody had ever added it up. A tool sizes the order from the fields it is given. The record →
Buy the decision, not another add-on.
The In-Stock Engine is managed inventory planning: one build that models your catalog, then a weekly rhythm of suggested POs, transfers and risk flags, run by a dedicated account lead and analysts. Linnworks keeps running your orders, listings and stock sync, and we leave its setup alone. The engine runs beside the forecasting add-on, or replaces it with the built workbook. Both are normal. The product is the same either way: order-by dates that are owned, every week, by name.
Worth twenty minutes if you hold 50 or more SKUs of real stock on 30 to 120 day lead times. Under that, book nothing: the free map and the health score are built for exactly you.
The three questions this page gets.
Does Volumetris replace Linnworks?
No. Linnworks runs orders, listings, warehouses and shipping, and we run none of it. We plan what to buy, when and how much, beside whatever runs your orders. If you are leaving Linnworks over order management, we will tell you on the call that we are the wrong answer.
Can you work from our Linnworks data?
The build works from the exports you already have: channel reports, supplier terms and whatever sales history you can hand over. Configuring Linnworks is not the product, so this is not an integration or a migration service.
What does it cost next to the Linnworks add-on?
Different line items for different jobs. The build is $1,500 once, Core is $1,250 a month, Partner is $2,250, published in full on the services page. Linnworks prices by order volume and quotes each customer, which is why no Linnworks prices appear on this page.
Linnworks belongs to its owner. Inventory Planner is a product of Sage. Linnworks’ descriptions are drawn from its own website and documentation, October 2026, and appear for factual comparison only. No affiliation or endorsement is implied, in either direction.
