Purchasing & inventory

Know what you have and what is coming

Order from suppliers at their prices, receive deliveries in parts, and see stock on hand, reserved and available in every warehouse and location. Every movement is recorded in a ledger that is never edited.

Stock

On hand, reserved, available

For every product and location, Modulix keeps what is physically there, what is promised to confirmed sales orders and what you can still promise. Receipts from purchase orders, shipments from sales orders, transfers and adjustments each become a numbered movement in the stock ledger, linked to the document that caused it.

The ledger is never edited afterwards, so the history of every item can be traced.

  • Adjustments with a reason

    Stock counts and corrections recorded with why they happened.

  • Units of measure

    Whole numbers for each or box, decimals for kilograms, litres or metres.

  • Filters and views

    By warehouse, product or SKU, saved for the people who need them.

Product catalog

One catalog for buying, stocking and selling

Products and services are defined once, with their SKU, category, unit of measure, sales price, purchase cost and tax class, and reused by quotations, orders, invoices, purchase orders and bills.

Variants such as colours or sizes each get their own SKU, price, cost and stock. For every item, record which suppliers sell it, under which reference, at what price and lead time, and which one is preferred.

  • Variants

    Generate variants from options and price each one separately.

  • Pictures

    Product pictures shown in the catalog and on the product page.

  • Suppliers per item

    Supplier SKUs, prices, minimum quantities and lead times.

    Receive, issue or adjust stock that comes and goes without a document.

  • Receiving permission

    Recording deliveries is a separate permission, so warehouse staff can receive goods without creating orders.
