Managing Stock

Path: Catalog › Stock › Stock Management (/admin/stock)

Stock management is the heart of e-commerce operations. Merzio lets you track products, variants, availability, reservations, and warehouses in one place. In this guide you'll learn how to manage your stock efficiently and set up warehouses.

The Stock Management page

The Stock Management page gives you an overview of all products and their stock. On it you select products and edit them all at once.

Search and filtering

At the top of the page there is a search box and a Filter button; the chosen filters appear as removable chips:

• Search — Enter a product name, SKU, or EAN (variant SKUs, EANs, and barcodes are searched too)
• Warehouse — Select a specific warehouse to see stock for that warehouse only (default All Warehouses)
• Category — Narrow the list to one category
• Stock Status — All Stock, In Stock, Low Stock, Out of Stock, or To reorder (negative stock)

Sorting

The filters also include Sort By:

• Name: A to Z / Name: Z to A — Alphabetically by name
• Stock (Low to High) / Stock (High to Low) — By stock quantity
• Position A–Z / Position Z–A — By warehouse position

Import and export

The page header has two buttons:

• Export stock — Downloads a file with the current stock data
• Import stock — Opens a dialog where you upload the downloaded or edited file (CSV or Excel) and update stock in bulk

See Import and export for details.

What you see for each product

Each row shows:

Column	Description
Product	Thumbnail, name, and product codes (SKU, EAN)
Position	Position in the warehouse (shelf / bin)
On hand	Physical quantity in stock
Reserved	Quantity held for carts and orders
Available	Stock available for sale (on hand minus reserved)
Delivery	Number of working days for delivery set on the item

At the end of the row there are icons to view the product in the shop and to edit it. If stock is negative, a note under the row shows how many units need to be ordered.

Products with variants

If a product has variants (e.g. different sizes or colors):

• Click Variants (X) to expand the list of all variants
• Each variant has its own SKU, EAN, position, and stock
• Stock is counted separately for each variant

Stock actions

First select one or more products or variants with the checkbox (the checkbox in the header selects everything on the page). A bar appears at the bottom with the number of selected items and an action switch: Add, Subtract, Transfer, Position, and Delivery (days).

Add stock

1. Select products or variants and choose Add in the bar
2. Enter the quantity you want to add (a positive number)
3. Optionally select a warehouse — if you leave the field empty, the change is applied to all active warehouses
4. Optionally enter a note
5. Click Update Stock

Subtract stock

1. Select products or variants and choose Subtract in the bar
2. Enter the quantity to subtract (a positive number; the system applies it as a negative change)
3. Optionally select a warehouse and enter a note
4. Click Update Stock

Transfer between warehouses

The Transfer action appears when you have more than one warehouse.

1. Select products or variants and choose Transfer in the bar
2. Choose From warehouse and To warehouse — they must be different
3. Enter the quantity to move
4. Optionally enter a note
5. Click Transfer

WARNING

If the source warehouse does not have enough stock, the transfer is rejected with an error stating the available quantity.

Bulk change of position and delivery

• Position — after choosing a warehouse, enter the warehouse position for all selected items at once.
• Delivery (days) — set the number of working days for delivery for many items at once. An empty field = leave unchanged; ticking Reset to Stock settings default clears the override. You can also edit delivery directly on an item via the small Delivery chip (truck icon) in the stock list.

Warehouses

Path: Catalog › Stock › Warehouses (/admin/warehouses)

Warehouse list

Warehouses are shown in a table with search. For each warehouse you see:

• Name and code — e.g. "Main warehouse" (ESHOP); the default warehouse has a Default badge
• Location — the warehouse address
• Contact — phone or e-mail
• Role — badges Pickup point, Supplier, and On storefront (the warehouse is shown as an availability line on the product)
• Status — Active / Inactive

Use the ⋯ menu at the end of the row to edit the warehouse (Edit), make it the default (Set as Default), or remove it (Delete).

Adding a new warehouse

Click Add Warehouse in the page header. A dialog opens with these fields:

• Name (the warehouse name) and Code — e.g. "Second warehouse", code "SK02"
• Address, City, Postal Code, Country
• Phone and Email
• The Active and Set as Default toggles
• Pickup Point Settings — for personal pickup
• Supplier Warehouse and Storefront Display — see Warehouses & Suppliers

When you're done, confirm with Create (when editing, Update).

Reservations

Path: Catalog › Stock › Reservations (/admin/stock/reservations)

The Stock reservations page shows goods currently held for orders and carts. At the top there are four figures: Reserved units, Orders holding stock, Carts holding stock, and Oldest reservation.

• Use the All / Orders / Carts tabs to narrow the list; the Newest / Oldest switch changes the order, and the search looks up a product, SKU, order number, or e-mail.
• Each card is one order or one cart with its items, number of units, and the time the reservation was created or when it expires.

Each reservation has two actions:

Action	What it does
Release	The reservation is cancelled and the goods are available for sale again. Stock levels do not change.
Complete	Orders only. The order's reservations end and stock is reduced by the ordered quantity (only once).

If stock has already been reduced for the order (the Stock already lowered badge), a single End reservation button is offered instead — the reservation just ends and stock is not reduced again.

In bulk: tick several cards and choose Release or Complete in the floating bar at the bottom. Bulk completion skips carts. You confirm every action in a dialog.

When to use it

Reservations are normally released on their own (after the cart timeout, or when an order is fulfilled or cancelled). Use this page when goods are "stuck" in a reservation — e.g. on an old unfulfilled order — and you need to put them back on sale.

Watchdogs

Path: Catalog › Stock › Watchdogs (/admin/stock/watchdogs)

The Watchdog Management page lists customers waiting for a product to come back in stock. For each entry you see the product (and variant), e-mail, sign-up date, notification date, and status (Active, Notified, Cancelled). You can search the list, filter it by status, and download it with the Export button.

You turn the watchdog on in Stock settings (the Reservations & alerts tab). When the product is back in stock, the subscribed customers receive an e-mail notification.

Stock Settings

Path: Catalog › Stock › Stock Settings (/admin/settings/stock)

Reservations, back-in-stock alerts, orders into negative stock, availability texts, and bulk tools (including the Global Stock Status overview) are described in the separate chapter Stock settings. In short:

• Enable Stock Reservations — stock is reserved as soon as an item is put in the cart; Reservation Timeout (minutes) (1–1440, default 30) sets after how long an inactive cart's reservation is released
• Enable Watchdog — sold-out products in the shop show an option to be notified when they are back in stock
• Allow Backorder to negative stock (Global) — whether goods that are not in stock can be bought

Tips and best practices

• Regular export — Export your stock regularly as a backup
• Use warehouses — If you have several physical locations, create a warehouse for each one
• Monitor variants — Regularly check that all variants are properly stocked
• Shorten the reservation time — If you have higher traffic, shorten the reservation time to fewer minutes
• Check reservations — Look at the Reservations page now and then and release the ones that no longer have a reason to hold goods
