What's the difference between a Master Product and an Inventory Lot?

This is the most important concept in Nstock.

• A Master Product is the definition or blueprint of an item. It holds the core, unchanging information like its Name, SKU, Category, and the Unit it's measured in. It does not have a quantity. Think of it as the entry in a catalog.
• An Inventory Lot is a physical batch of that item in your stock. It has a quantity, a specific lot number, an expiry date, and a location. You can have many different lots of the same Master Product.

How does Unit Conversion work?

Nstock allows you to track inventory in one unit while purchasing in another.

• Inventory Unit: The primary unit used for BOMs and internal stock tracking (e.g., 'g' or 'ml'). This is set in the Master Product.
• Purchase Unit: The unit you buy from your supplier (e.g., 'kg' or 'L'). This is set when you create a material order.
• Conversion Factor: Nstock auto-converts common units (for example kg to g, lb to g, L to ml, and gal to L). If your units are custom (for example case to each), provide a custom Conversion Factor. Example: if you buy a 25kg bag of flour but use grams, factor is 25000.

Which CSV upload should I use?

• Master Products CSV: To define many products at once. This creates the blueprints.
• BOMs CSV: To define many product recipes at once. The components must already exist as Master Products.
• Stock Inventory CSV: To add initial quantities of items you already have on hand. The items must first be defined as Master Products.
• Suppliers CSV: To import your supplier list at once, instead of adding them one at a time.

Raw Materials Stock

View and manage your current raw material stock levels. Materials are grouped by SKU. Click on a material to expand and see individual lot details, edit details, or adjust quantities.

Finished Goods Stock

Overview of all manufactured products ready for sale or shipment. This lists items that have completed the production process. Batch codes are displayed and link to their production batch tickets for traceability.

Cycle Count

Tools for performing physical inventory counts.

• Scan & Update: Use your device's camera to scan a barcode, find the item, and quickly update its quantity.
• Manual Quick Edit: A table-based view of all inventory lots. Allows for rapid, spreadsheet-like adjustments to quantities and locations. Your progress is saved as a draft automatically.

Place Material Order

Initiate orders for new or existing raw materials.

• Define & Order New Material: For items not yet in your Master Products. Define its core details (SKU, units, etc.) while creating the order.
• Repurchase Existing Material: A quick form to reorder a single, existing raw material.
• Create Purchase Order (PO): Build a formal PO with multiple line items for a single supplier. Best for bulk ordering.

Pending Material Orders

Manage and receive materials that have been ordered but not yet added to stock. Click "Receive" to process incoming shipments, record quantities (passed/failed QC), and update inventory.

Box Inventory

Manage your stock of shipping boxes and other packaging materials.

Waste Log

Track all instances of raw material or finished good wastage, including associated costs.

Lot Documents

Attach documents to any material lot from the lot's detail view. Pick a typed slot — CoA, SDS, CoC, TDS, Allergen Statement, Kosher/Halal/Organic/Non-GMO/Fair Trade/Vegan Certificates, Country of Origin Certificate, Nutritional Panel, Test Report, REACH/RoHS Compliance, or Other with a custom label — then upload a file or paste a link. Documents stay attached to the lot as it moves through receiving and production, and carry through to waste or end-of-life records if that lot is ever logged as waste.

Master Products

The central definition for every item you use or sell, including raw materials and finished goods. This is where you set an item's SKU, name, inventory unit, and category.

Bills of Materials (BOMs)

Your product recipes. A BOM links a finished good Master Product to the specific raw material Master Products (and their quantities) required to make it. Secondary items (like an unbranded component made from its own BOM) get their own SKU and cost, which then rolls up into the cost of any finished good that uses them.

Sales Orders

View, create, and manage customer orders. Fulfilling an order will automatically deduct the correct finished goods and shipping boxes from your inventory.

Sales Quotes

Build a sales quote for a finished good or secondary product using real-time FIFO and BOM cost data, so you always know your margin at the price you're quoting. Buyers only ever see the sell price — internal cost and margin figures stay visible to your team only.

Suppliers

Manage your supplier list, view what you buy from each one, and create a purchase order directly from a supplier's page. POs can be emailed straight from Nstock with a reorder template or a custom message.

Start Production Run

Initiate a production batch from a BOM. You'll specify the quantity to produce and select which inventory lots of raw materials to consume. This deducts raw materials and creates a pending batch.

Pending Batches

Track batches that are in progress. Once production is complete, you can "Receive" the batch to add the finished goods into your inventory.

Inventory Projection Analysis

Uses AI to project inventory depletion times based on historical usage data.

AI Reorder Advisor

Leverages AI to analyze inventory, usage, and lead times to provide smart reorder suggestions.

Finance Reports

A dedicated section with key financial reports:

• Inventory Valuation: A snapshot of the total value of your raw materials and finished goods.
• Monthly Report: A frozen, point-in-time ending inventory value for each closed month, generated automatically — ready to hand to finance without it changing underneath them.
• Cost of Goods Sold (COGS): Calculates the cost of materials consumed for fulfilled orders in a given period.
• Purchase Spend: Analyzes total spending on raw materials, filterable by supplier and date.
• Waste: A detailed report on the value and quantity of all wasted items.
• Inventory Turnover: How many times your average inventory value was sold through in a given period.
• Inventory Aging: Groups on-hand raw materials and finished goods into 0-30/31-60/61-90/90+ day buckets so you can spot slow-moving stock.
• WIP Valuation: The value of materials currently consumed into active production batches.
• Open Purchase Commitments: Purchase orders placed but not yet fully received — useful for cash-flow planning.

The settings area allows you to manage your profile, company details, users (as admin), production settings, notification preferences, billing, and system data modes.

Manage Units, Categories & Suppliers

Create, edit, and manage custom lists for units of measure, product categories, and suppliers to tailor the application to your specific business needs.

Integrations

Connect Nstock to the tools you already run your business on, from the Integrations page in your account. Every integration below is unlocked by the same Integrations add-on starting at the Starter plan, and included free at the Business plan.

• Shopify: Connect your store to automatically create orders in Nstock and deduct finished goods inventory as orders are fulfilled, plus restock automatically on refunds.
• WooCommerce: The same order-and-inventory sync as Shopify, for WordPress/WooCommerce stores. Paste the Consumer Key/Secret pair generated in your WordPress admin — no OAuth redirect required.
• QuickBooks Online: Connect via a standard "Sign in with Intuit" flow, no keys to copy. Once connected, map your Chart of Accounts (Inventory Asset, COGS, Inventory Adjustment, Sales Income), then optionally turn on a monthly inventory journal entry and/or order-to-invoice syncing — both are off by default, since they write real financial data to your books.

Custom Email Sending

Verify your own company domain so purchase order and sales quote emails send from your own address instead of Nstock's. Available on the Business plan or as an add-on.

Billing & Subscription

View your current plan, switch plans at any time, and add or remove extra features from the Billing page.
