Purchase returns represent a critical component of the procure-to-pay cycle in any business, serving as a mechanism to correct errors, handle defects, or manage over-deliveries while safeguarding cash flow and maintaining accurate inventory records. By processing returns effectively, organisations can ensure that their financial statements remain compliant with standards like GAAP or IFRS, prevent distortions in inventory costs, and foster stronger vendor relationships.
The return process covers accounting and supply chain principles, as outlined by bodies like APICS, which emphasise reverse logistics to minimise waste and optimise resource recovery.
In this post, we will learn about how to handle purchase returns in Dynamics 365 Business Central to maximise efficiency while maintaining accurate costing and traceability.
Core Concepts & Terminology
To master purchase returns in Business Central, it's essential to understand the foundational elements that drive the process.
The Purchase Return Order is the primary document for handling returns that involve physical goods, allowing you to manage both the shipment back to the vendor and, optionally, the financial reversal in one place. This is particularly useful when items need to leave your warehouse, as it generates shipment documents for logistics teams.
In contrast, the Purchase Credit Memo focuses solely on the financial aspect, reversing the invoice amount without necessarily involving physical movement (with some exceptions that we will learn later in this post), which is ideal for services or adjustments where goods aren't returned.
A key feature to enable is Exact Cost Reversing Mandatory, found in the Purchases & Payables Setup.
When activated, this ensures that returns reverse the exact original cost from the purchase receipt, rather than applying a current average or estimated value, which keeps your inventory valuation precise and compliant with accounting standards.
Tools like Get Posted Document Lines to Reverse pull in data from original receipts to populate your return order with accurate quantities and costs, while Get Return Shipment Lines allows you to consolidate multiple shipped returns into a single credit memo later.
These concepts ensure traceability, with every step linking back to the source transaction for audits and reporting.
Critical Setup and Configuration
Setting up purchase returns in Business Central begins with a few straightforward configurations to align the system with best practices.
Start by navigating to the Purchases & Payables Setup page using the search function (Alt+Q).
Here, check the box for Exact Cost Reversing Mandatory to enforce accurate cost reversals. This is a simple toggle, but one that I recommend to most of my clients to maintain inventory integrity.
Without it, returns will default to the item's costing method, potentially leading to valuation drifts over time. However, in some cases, organisations might use the default costing method when returning items to suppliers.
Like what I always say when I train and consult clients and consultants, do not make assumptions when discussing costing or tax-related features of any business applications. Always check with the finance team or the company auditor before making the final decision.
Additionally, consider defining Return Reason Codes under Purchasing Setup. These are predefined categories like "Damaged Goods" or "Over-Delivery" that you can assign to return lines, enabling better analytics through reports.
This setup takes just minutes but pays dividends in tracking vendor performance and identifying patterns in returns, all without any customisations.
Workflow 1: Simple & Immediate Return
For businesses that do not use warehouse management features and teams that prefer a quick workflow to return goods to a supplier, the simple, immediate return workflow in Business Central allows you to handle everything in a single document.
Begin by creating a new Purchase Return Order from the list page.
Fill in the vendor details, then, on the action bar, use the Get Posted Document Lines to Reverse function to pull in lines from the posted purchase invoices or receipts; this action automatically brings over quantities, costs, and item tracking lines.
If it's a partial return, adjust the quantity on the line as needed.
Note that the return order lines can be shipped from different locations and can have different reason codes, as shown in the picture below:
Once ready, post the document by selecting Ship and Invoice (or first post the Return Shipment for physical dispatch, then post the Invoice separately).
At this point, Business Central automatically generates and posts a Posted Purchase Credit Memo, reversing the financials and updating your inventory and ledger in one seamless step.
This method is efficient for quick resolutions, ensuring minimal disruption to operations while maintaining full traceability.
Workflow 2 – Segregated Duties / Delayed Crediting
Organisations that maintain segregated duties, such as those requiring quality checks and formal approvals, or when warehouse tasks are needed to pick and ship goods back to the supplier, Business Central supports a more controlled workflow that separates handling physical stock and the financials.
Quality typically initiates the return by identifying the issue and notifying procurement. Procurement then creates the Purchase Return Order, populating lines via Get Posted Document Lines to Reverse to ensure exact matching to the original transaction.
Next, the procurement or the warehouse team posts the Return Shipment, which generates a posted shipment document and allows the dispatch of the goods without touching the finances yet.
The vendor receives the items and provides confirmation, often with a document that Quality reviews before alerting Accounts Payable (AP).
AP then opens a new Purchase Credit Memo, fills the vendor header, and uses Get Return Shipment Lines to select and import all relevant shipped but uninvoiced return shipments, even from multiple original purchases.
After verifying the lines, AP posts the credit memo to complete the financial reversal.
This approach preserves segregation of duties, reduces risks of premature crediting, and allows batching of multiple returns into one vendor document for efficiency, all while leveraging out-of-the-box features for automation and accuracy.
Post-Acceptance Resolution Options
Once the vendor accepts the return and confirms receipt of the goods, Business Central offers flexible ways to resolve the transaction based on your agreement.
For a fast refund or credit, simply post the Purchase Credit Memo as described in the workflows above. The system applies the credit to the vendor's ledger, which can offset future invoices or trigger a direct refund if already paid.
If a replacement is needed, where the vendor sends back identical items, add a line to the Purchase Return Order with a negative quantity.
Then, use the Move Negative Lines function, which automatically creates a new Purchase Order for the positive quantity, allowing you to receive the replacements.
For substitutions, where an equivalent but different item is agreed upon, edit the item number on the return line or add a new line for the substitute.
If there's a price difference, incorporate an item charge line to adjust the cost positively or negatively, ensuring the valuation reflects the new agreement. These options integrate seamlessly with inventory and finance, supporting business continuity without custom tools.
Reports You Should Know
Business Central does not include many reports to monitor and analyse purchase returns, but you can use pages and lists to gain insights without additional setup.
The Inventory Valuation report is invaluable for verifying that costs have reversed correctly, showing how returns impact your overall stock value. The same report is available in a Power BI app.
For tracking open processes, the Purchase Return Order List provides an overview of all active return orders, including statuses and details.
The Vendor – Detail Trial Balance helps monitor open credits on vendor ledgers, ensuring they're adequately applied.
Finally, if you've used Return Reason Codes, the Item Ledger Entries page shows the costs and quantities returned, including the reason codes. Using Analysis Mode on this page allows users to query items returned by reason, value and even vendor.

In Summary
Purchase returns in Business Central allow the return of physical goods to vendors and serve as the first step of a vendor return process that can end with a posted credit memo applied to existing pending invoices, a replacement, a substitution or even a vendor refund.
Choose a simple workflow that supports the shipment and the invoicing tasks concurrently or a two-step process if more control is required. As always, before deciding on a configuration that affects costing, consult the finance team or a qualified professional.
