Dynamics 365 Business Central – Purchasing & Inventory
Business Central is a business management solution for small and mid-sized organizations that automates and streamlines business processes and helps you manage your business. Highly adaptable and rich with features, Business Central enables companies to manage their business, including finance, manufacturing, sales, shipping, project management, services, and more. Companies can easily add functionality that is relevant to the region of operation, and that is customized to support even highly specialized industries.
Today we are going to focus on Purchasing & Inventory features.
1. PURCHASING
You create a purchase invoice or purchase order to record the cost of purchases and to track accounts payable. If you need to control an inventory, purchase invoices are also used to dynamically update inventory levels so that you can minimize your inventory costs and provide better customer service. The purchasing costs, including service expenses, and inventory values that result from posting purchase invoices contribute to profit figures and other financial KPIs on your Role Center.
You must use purchase orders if your purchasing process requires that you record partial receipts of an order quantity, for example, because the full quantity was not available at the vendor. If you sell items by delivering directly from your vendor to your customer, as a drop shipment, then you must also use purchase orders. In all other aspects, purchase orders work the same way as purchase invoices.
You can have purchase invoices created automatically by using the OCR (Optical Character Recognition) service to convert PDF invoices from your vendors to electronic documents, which are then converted to purchase invoices by a workflow. To use this functionality, you must first sign up for the OCR service, and then perform various setup. For more information, see Process Incoming Documents. Products can be both inventory items and services.
For all purchase processes, you can incorporate an approval workflow, for example, to require that large purchases are approved by the accounting manager. For more information, see Using Approval Workflows.
The following table describes a sequence of tasks, with links to the topics that describe them.

2. INVENTORY
For each physical product that you trade in, you must create an item card of type Inventory. Items that you offer to customers but do not keep in inventory you can register as catalogue items, which you can convert to inventory items when necessary. You can increase or decrease the quantity of an item in inventory by posting directly to the item ledger entries, for example, after a physical count or if you do not record purchases.
Inventory increases and decreases are naturally also recorded when you post purchase and sales documents respectively. Transfers between locations changes inventory quantities across your company’s warehouses.
To increase your overview of items and to help you find them, you can categorize items and give them attributes to search and sort by.
Planning for items to fulfil demand is covered as part of supply planning functionality.

Inventory Reconciliation
When you post inventory transactions, such as sales shipments, purchase invoices, or inventory adjustments, the changed item costs are recorded in item value entries. To reflect this change of inventory value in your financial books, the inventory costs are automatically posted to the related inventory accounts in the general ledger. For each inventory transaction that you post, the appropriate values are posted to the inventory account, adjustment account, and COGS account in the general ledger. Even though inventory costs are automatically posted to the general ledger, it is still necessary to ensure that the costs of goods are forwarded to the related outbound sales transaction, especially in situations where you sell goods before you invoice the purchase of those goods. This is referred to as cost adjustment.
Item costs are automatically adjusted when you post item transactions, but you can also adjust item costs manually. The following table outlines related tasks.
