What common problems do warehouses face when shipping with PostNL?
Warehouses that ship with PostNL often manage high parcel volumes, tight cut offs, and a mix of domestic Netherlands deliveries and international consignments. The difficult part at the bench is not printing a label, it is choosing the correct PostNL service for each order quickly and consistently. The right decision can change with the total order weight, the total order value, the delivery postcode, and the destination country. During peaks, manual checks multiply and even experienced staff can miss a detail when the belt is full.
Common issues include misreading a postcode segment, totalling the wrong weight across multi line orders, or overlooking a value threshold that should trigger a signature or enhanced cover. When teams rely on memory, spreadsheets, or desk guides, these small slips become relabelling, manual corrections, missed inductions, or delivery failures that then create customer service workload. Throughput becomes sensitive to who is on shift, and training takes longer because the important knowledge lives in people not in systems.
Clarus WMS removes this friction by automating carrier and service selection for PostNL. Instead of asking packers to decide at the bench, you define clear rules once. Clarus calculates order totals, checks address details, evaluates your conditions, and assigns the correct PostNL service automatically. Labels, tracking, and shipment records follow in the same workflow. Any time saving or efficiency figure referenced here is an estimate, because each operation has a different order mix, staffing profile, and layout.
How can a WMS automate carrier selection for PostNL shipments?
In Clarus, carrier assignment is native. You express your shipping policy as rules, and Clarus applies that logic the moment an order is ready to ship. The rules engine evaluates four core inputs that are present on every sales order, the total order weight, the total order value, the delivery postcode, and the destination country. Based on those inputs, Clarus assigns PostNL as the carrier and selects the correct PostNL service automatically. No middleware is required for the capabilities described here, and configuration does not require developers.
The workflow is straightforward and repeatable. First, Clarus receives the sales order from your commerce platform or ERP. Second, Clarus calculates the totals across all lines, so the full weight and total value are accurate without manual arithmetic. Third, Clarus evaluates the delivery address, including postcode and country. Fourth, Clarus matches those inputs to your rule list and assigns the appropriate PostNL service. Finally, Clarus generates the label and tracking and records the shipment against the order while keeping inventory movements in sync. Packers see the service already chosen, confirm the pick, print the label, and move the parcel on without extra checks.
This approach removes decision time at the bench and reduces error rates. If your shipping policy changes, you update the rule once in Clarus, and all future orders follow the new path. If volumes spike, the rules continue to apply instantly, so throughput remains steady even when you rotate staff or bring in new starters. Supervisors can review which rules applied to which orders, which helps with governance and with continuous improvement. Any improvement figures you calculate will be estimates, since no two operations are the same.
Can Clarus assign PostNL services based on weight, value, or delivery location?
Yes. Clarus can assign PostNL services using rules that evaluate total order weight, total order value, delivery postcode, and destination country. These conditions cover real world scenarios and can be combined or prioritised to match your policy. Below are practical examples to illustrate the pattern. Treat them as examples rather than templates, your thresholds and service names will reflect your operation.
• Route light domestic parcels to a standard or economy PostNL option when total order weight is below your threshold and the postcode is within normal coverage.
• Apply a signed or enhanced cover PostNL service when the total order value exceeds a defined limit, while keeping the delivery speed aligned with customer expectations.
• Use a tracked or timed PostNL service for selected postcode ranges where performance data supports a specific choice or where customers expect tracking as standard.
• Direct all non Netherlands destinations to an appropriate PostNL international pathway by using the destination country condition, while leaving domestic rules unchanged.
• Enable a Saturday specific rule that only applies when the requested delivery date falls on a Saturday and the postcode is eligible, while other days follow your standard logic.
Because Clarus calculates totals from the order lines, staff do not need to add up weights or values at the bench. This avoids edge case errors such as missing a heavy line on a multi line order or misreading a decimal point. If your policy includes postcode exceptions, the postcode condition captures them without relying on memory or separate lookup tables. You can also order rules so that safeguards run before general rules, and you can stack conditions inside a single rule when a specific combination is required.
Any efficiency or cost saving claim should be treated as an estimate. Many teams find that removing manual checks reduces decision time and relabelling, others see the main gain in fewer exceptions and simpler training. The exact result depends on your processes and the service mix you use with PostNL.
Do I need custom development to use PostNL with Clarus WMS?
No, not for the functionality described here. Clarus provides native automation for assigning PostNL and selecting PostNL services based on total order weight, total order value, delivery postcode, and destination country. Configuration happens in the Clarus dashboard with plain language controls. You can create and edit rules, test scenarios with example orders, set rule priority, and enable changes without writing code. Once saved, the next eligible orders follow the updated logic.
You also do not need middleware for these capabilities. By keeping carrier assignment, label generation, tracking, and inventory updates inside Clarus, you remove an extra layer that can fail or drift from policy. Teams gain a single place to define and audit how PostNL is used. Training becomes simpler because staff learn one workflow, and the chance of unofficial workarounds reduces across sites and shifts.
If your policy evolves, you extend the rule set in the same place. For example, add a new postcode exception, adjust a value threshold, or combine conditions to capture a new edge case. Supervisors can review which rule fired for each order, so outcomes are explainable and improvements are easier to validate. Any timeline for setup or optimisation will be an estimate until measured in your own environment.
How does Clarus keep orders, labels, tracking, and inventory aligned for PostNL?
Clarus keeps the shipping workflow in one system so data stays aligned. Sales orders flow into the WMS. Inventory updates as picks are confirmed. When an order is ready to ship, the PostNL assignment has already been made by your rules. Clarus then generates the required label and tracking, and records the shipment against the order while updating inventory at the same time. This removes copy and paste steps and reduces the chance of mismatches across systems.
At the bench, packers see a single screen that guides the task. Because service choice is made upstream, the focus is on confirming picks and printing labels rather than checking eligibility. For supervisors, the benefit is visibility. You can see rule definitions, rule order, and which orders matched which rules. That makes it easier to refine policy and to explain outcomes to colleagues and customers. Customer service teams benefit from the same clarity when answering delivery queries.
If an exception occurs, the audit trail inside Clarus helps you find and fix the root cause without switching between multiple tools. You can trace which rule applied, whether a threshold was met, and whether a postcode match triggered a specific path. This supports continuous improvement and reduces time spent on investigations.
What does setup look like, and how can we validate our rules before go live?
Setup follows a structured sequence that most teams complete without developers. First, review your current use of PostNL, including service types, weight and value thresholds, and any postcode or country based exceptions. Second, model that policy as rules inside Clarus using the native conditions for total order weight, total order value, delivery postcode, and destination country. Third, create a set of sample orders that reflect your real scenarios and use them to test the rules in Clarus. Fourth, enable the rules in your live environment and monitor the first shipments for confirmation.
The Clarus dashboard uses clear fields and plain language so non technical users can configure and adjust logic. You can label each rule with a description so colleagues understand the intent, and you can drag to reorder rules when priorities change. If you discover a new exception, for example a postcode that requires a different service, you add a condition and test it immediately. Any quoted timelines for setup or training are estimates, because operations differ in data quality, service mix, and availability of test orders.
Training focuses on two groups. Packers learn the simpler bench flow, the service is already assigned, they confirm picks and print labels. Supervisors learn how to read and edit the rule set, how to test changes safely, and how to review which rules applied to which orders. This gives you control with less complexity and reduces reliance on single points of knowledge inside the team.

FAQ
Can Clarus apply different PostNL services for domestic and international orders automatically?
Yes. You can use the destination country condition to route non Netherlands addresses to PostNL international pathways while domestic parcels follow your NL rules. No custom development is required for this routing.
What happens if more than one rule could match a single order?
You set the priority. In Clarus, rules are ordered, so you can place a high value safeguard before a general weight based rule. You can also combine conditions to capture a specific scenario in one rule.
Do packers still need to calculate weight and value at the bench?
No. Clarus calculates total order weight and total order value from the order lines. Packers do not need to add up weights or check values manually, which reduces the risk of mistakes.
How are labels, tracking, and inventory kept in sync when shipping with PostNL?
Clarus generates the label and tracking in the same workflow that confirms the pick and ships the order. The shipment is recorded against the order, and inventory is updated at the same time, which keeps data aligned without copy and paste.
Do we need developers or middleware to go live with PostNL in Clarus?
No, not for the functionality described on this page. Clarus provides native service assignment automation and configuration in the dashboard that non technical users can manage. Any timeline claims are estimates, but the process is straightforward, review your policy, model it as rules, test, then enable in production.
