Functionality in Dynamics GP Compared to D365 Business Central | Purchase Orders

For organizations planning a transition from Dynamics GP to Dynamics 365 Business Central, purchase order (PO) processing is a noticeable area of change. While both systems support core purchasing requirements, Business Central introduces a more flexible, automated approach.

This article discusses the key differences you can expect when managing purchase orders in GP compared to Business Central.

To see a complete side-by-side system comparison, watch the recording below:

Issuing Purchase Orders in Dynamics GP and Dynamics 365 Business Central

The PO entry experience in Dynamics GP uses a more traditional window-based interface where users select a vendor, enter item lines, designate sites, and optionally apply prepayments. In GP, purchase orders must be printed before they move to a Released status, which is required for MRP and downstream processes. Non-inventory items can be entered, but adjusting the account requires drilling into additional detail windows.

Business Central provides a more streamlined and modern experience. The PO entry page uses an Excel‑like grid, allowing users to tab quickly across fields or copy and paste directly from spreadsheets. Vendor lookups support flexible “contains” searches, and dimensions such as department or division can be updated inline—with changes cascading to all item lines automatically. Business Central also offers more flexibility when adding non‑inventory lines, allowing users to select G/L accounts, resources, fixed assets, or charges without opening secondary windows.

Printing, Sending, and Approvals

Both systems offer options for printing and sending POs, but Business Central enhances the workflow with built‑in PDF generation and modern email capabilities through Outlook. Templates can be customized visually, including branding elements such as logos and headers. Business Central also integrates with approval workflows and Power Automate, enabling organizations to build consistent purchasing processes with automated notifications and routing.

Receiving Items: Full and Partial Receipts

Receiving items works differently between GP and Business Central. In GP, users must choose between recording a receipt-only transaction or a combined shipment/invoice entry. Receiving non‑inventory items creates an immediate G/L impact in GP. Partial receipts are supported, and any remaining quantities stay open on the PO.

Business Central separates the concepts of receiving and invoicing, especially for non‑inventory lines. Inventory items update expected cost on receipt and finalize costs on invoice. Non‑inventory items do not hit the G/L until the invoice is entered. Business Central’s posting preview helps users understand exactly which G/L and item ledger entries will be created before committing the transaction.

Invoice Matching and Purchase Price Variance

Invoice matching is handled differently in each system. Dynamics GP processes invoice matching in a dedicated window, allowing users to auto‑match remaining lines and edit prices as needed. When invoice prices differ from receipt prices, GP records the difference as purchase price variance (PPV).

Business Central takes a different approach. Instead of posting PPV to a dedicated account, the system reverses the original expected cost entry and reposts the corrected actual cost. This creates cleaner item valuations and sends the adjustment to the appropriate inventory or expense accounts. For organizations seeking tighter cost accuracy, this automatic correction can be a major advantage.

Vendor‑Specific Pricing and Discount Capabilities

One of the standout differences between GP and Business Central is the flexibility of vendor pricing in Business Central. While GP tracks only the last purchase cost for an item, Business Central allows organizations to maintain detailed vendor purchase price lists, including quantities, date ranges, and discount percentages. These structured vendor agreements reduce manual work and ensure that negotiated terms are consistently and automatically applied.

Two Key Advantages of Business Central:

• Advanced vendor pricing and discount automation: Business Central supports vendor‑specific price lists, quantity breaks, discount structures, validity periods, and vendor item references—functionality that GP does not provide out of the box.
• Modern receiving, invoicing, and costing workflows: Expected costs, automated reversals, and enhanced posting previews make Business Central’s purchasing lifecycle more transparent and accurate.

Both Dynamics GP and Dynamics 365 Business Central offer robust purchasing capabilities, but Business Central delivers a more modern, automated, and flexible experience—especially in areas like vendor pricing, cost adjustments, workflow integration, and data visibility.
