01 · What you get

What a Tradex integration gives you.

Faster PO-to-cash cycle

Buyers see orders acknowledged immediately and invoices delivered with complete shipment data, shortening their three-way-match time and speeding payment.

Accurate contract compliance

Negotiated pricing and payment terms are applied automatically during order intake and invoice generation, reducing disputes and manual price adjustments.

Clearer order and shipment visibility

ASNs and dispatch confirmations arrive in the buyer's procurement system with tracking data, so they know what is in-transit and can plan receipt and warehouse capacity.

Reduced approval bottlenecks

Orders that meet contract rules flow straight through; only exceptions need human review. Approval workflows are visible, so finance teams know where orders are stuck.

02 · When it's worth it

Where a Tradex integration earns its place.

If two or more of these are true, the integration usually pays for itself quickly.

Inbound purchase orders from buyer procurement systems via Tradex EDI
Punchout catalog sessions for account-based buyers
Contract pricing and discount terms application to POs
Automated order acknowledgement and ASN dispatch confirmation
Invoice and credit note exchange with buyer reconciliation
Approval workflow routing before PO acceptance
03 · The limits

Where off-the-shelf connectors fall short.

Vendor connectors are fine for simple cases. Here's where the real ones need more.

Punchout catalog configuration requires manual curation

Tradex punchout typically requires product selection, pricing tier mapping and content approval per buyer. Without integration, catalog updates must be manually republished, creating delays and drift risk.

PO-to-ERP mapping is not automatic

Tradex receives purchase orders but does not natively map buyer line items, cost codes or approval workflows to your ERP order structure. Manual intervention or custom scripting is needed to avoid order mismatches.

Contract pricing application is labour-intensive

Buyer-specific discounts, volume tiers and payment terms must be maintained separately in Tradex and your ERP. Without governed sync, pricing mismatches between what the buyer negotiated and what you invoice are common.

Invoice validation and three-way-match is incomplete

Tradex does not natively validate invoices against PO and shipment data, leaving buyers unable to automate approval. iWeb integration ensures invoices carry all required data for buyer three-way-match workflows.

Approval and exception queues lack visibility

Orders held for approval, orders with pricing mismatches, or rejected shipment notices can pile up in Tradex without clear ownership or escalation. Manual dashboards are often the only way to surface stuck orders.

04 · The real work

B2B procurement requires that contract pricing be applied consistently during order intake, and that every EDI message reach the buyer without silent failure; the integration layer is where that governance lives.

05 · Where it sits

Where this integration sits in your estate.

Tradex holds the commercial record. The iWeb integration layer manages the rules, mappings, monitoring and exceptions. The commerce platform presents the customer-facing experience. The estate map helps agree ownership before anything is built.

No platform lock-in. We integrate Tradex with the commerce core you already have, or the one you are moving to.

07 · Data flows

The data flows we wire.

Each flow has a direction and an owner. We agree both before a line of code is written.

→Into COMMERCE & ERP
←From ERP
↔BOTH WAYS
Buyer punchout catalog setup: Buyer-specific product data, pricing tiers and contract terms flow into Tradex punchout sessions so buyers see their negotiated catalogue and pricing when they log in
Account eligibility and cost-centre rules are applied at session time.
Purchase orders from buyers: Purchase orders arrive via Tradex EDI (cXML, PEPPOL or native format) and are mapped to your ERP order intake
Contract pricing validation and PO line-item matching happen before order acceptance.
Order acknowledgement and ASN: Order acknowledgements and advance shipment notices flow back to Tradex and are delivered to the buyer's procurement system so they can track receipt and invoice matching.
Invoice and credit note delivery: Invoices and credit notes are sent via Tradex EDI to the buyer, mapped to their PO and shipment data so they can reconcile and approve payment within their three-way-match rules.
Contract pricing and terms: Buyer-specific pricing, payment terms, shipping rules and approval thresholds are maintained in Tradex and applied during PO intake and invoice generation
Changes to contract terms flow through to new orders.
08 · How we build it

How iWeb configures the integration around your business.

Same method on every integration. The decisions come before the code.

  1. 01
    EDI mapping and inbound PO processing

    iWeb interprets Tradex EDI messages (cXML, PEPPOL, native format), maps buyer line items to your product and cost-centre structure, applies contract pricing validation, and posts orders to your ERP for acknowledgement and fulfillment.

  2. 02
    Contract pricing governance and application

    iWeb maintains buyer pricing tiers, volume discounts and payment terms in Tradex, applies them during PO intake, and ensures invoices reflect the agreed terms so buyers can reconcile without manual adjustment.

  3. 03
    ASN and invoice delivery back to buyers

    iWeb collects dispatch, tracking and shipment data from your ERP or WMS, maps it to Tradex ASN format, and delivers it to the buyer's procurement system for receipt matching and three-way-match validation.

  4. 04
    Approval and exception routing

    iWeb sets up approval workflows for POs that exceed thresholds, carry pricing exceptions or need sign-off against budget codes. Stuck orders and exceptions are surfaced with ownership and escalation paths.

  5. 05
    Tradex network credential and version management

    iWeb handles Tradex API authentication, EDI version upgrades and format changes so that schema drift or new buyer requirements do not break order intake silently.

10 · Experienced integrator

Built structured B2B order exchange before

iWeb has built Tradex integrations across multiple B2B commerce estates. We understand how Tradex sits alongside your ERP, order management, approval workflows and finance systems, and how to design reliable, governed flows for PO intake, contract pricing, ASN delivery and invoice exchange.

iWeb maps Tradex EDI formats (cXML, PEPPOL, native) to your ERP order schema, cost-centre structure and approval rules so POs land with no manual re-entry.
iWeb governs contract pricing so buyer tiers and negotiated terms are applied consistently during PO intake and invoice generation, reducing disputes.
iWeb handles Tradex network requirements (credentials, format versions, buyer account setup) and API changes without breaking order intake.
iWeb routes stuck POs, pricing exceptions and failed ASNs to named owners with clear escalation paths so exceptions do not accumulate silently.
iWeb collects dispatch and invoice data from ERP or WMS, formats it for Tradex EDI, and delivers it to buyers for receipt matching and payment.
11 · Before launch

What we test before launch.

Every one of these is rehearsed before a customer ever sees the integration.

Validate that test POs from Tradex arrive in ERP with correct line mappings, cost codes and buyer pricing applied, and that acknowledgements route back to Tradex without delay.
Confirm that pricing tiers in Tradex punchout match ERP pricing tables and that invoices reflect negotiated discounts so buyer three-way-match validation passes.
Test that rejected POs (invalid cost code, delivery address, product not on contract) trigger clear exception messages sent back to Tradex and logged with named owner.
Verify that ASN messages with shipment, tracking and PO reference data are sent to Tradex and delivered to test buyer account successfully.
Confirm that invoice messages with complete PO, shipment and payment-term detail are sent to Tradex and can be retrieved by test buyer for three-way-match.
Test approval workflows: orders below threshold pass through; orders above threshold route for approval and are visible in exception dashboard with SLA tracking.
Validate that Tradex credential rotation, EDI format changes and buyer account setup changes do not cause order intake failures or require manual intervention.
12 · Failure points

Common risks and where they bite.

We name these on day one. A risk written down is a risk you can plan around.

Silent PO rejections at contract validation

A buyer PO arrives with a cost code or delivery address not in the contract. The order is rejected at intake validation, but the buyer never receives an acknowledgement or error detail. Days pass before the buyer follows up.

Pricing mismatches between Tradex and ERP

Contract pricing is updated in Tradex but not in your ERP pricing tables, or vice versa. Buyer sees negotiated price in punchout but invoice shows standard price. Buyer withholds payment pending credit memo.

Missing or late ASN delivery to buyers

Shipments are dispatched from your warehouse but ASN messages fail to route to Tradex, or Tradex delivers them late. Buyer cannot match receipt to PO and holds payment pending manual ASN research.

Approval workflows blocking orders with no escalation

POs that need approval stack up in your approval queue because the approver is on leave or the approval threshold is unclear. Orders sit pending while the buyer wonders why they are not being fulfilled.

Unowned exception queues after go-live

Orders with validation errors, pricing mismatches or missing data land in an exception queue. No named owner monitors it, and buyers escalate to support weeks later about orders that never shipped.

14 · Questions

Common questions about Tradex integrations.

What EDI formats does iWeb support over Tradex?

iWeb handles cXML, PEPPOL, and Tradex native EDI formats. The integration interprets the format, maps buyer line items to your product and cost-centre structure, and posts orders to your ERP. Format changes or new buyer requirements are managed through the integration layer without storefront downtime.

How is buyer-specific pricing applied during PO intake?

iWeb maintains buyer pricing tiers, volume discounts and payment terms in Tradex for punchout display. During PO intake, iWeb validates each line item against the contract, applies negotiated discounts, and routes the order to your ERP with the correct pricing. If a line item is outside the contract, the order is flagged for approval.

What happens if a PO arrives with invalid cost codes or delivery addresses?

iWeb validates cost codes and delivery addresses against your ERP master data at intake. If a PO line is invalid, the order is held in an exception queue with a clear error message. iWeb sends a structured rejection back to Tradex so the buyer knows why the PO was not accepted and can resubmit with correct data.

How do ASNs and tracking get back to buyers?

iWeb collects dispatch data from your ERP or WMS (shipment date, tracking number, contents and destination). iWeb formats the data as a Tradex ASN message and sends it to Tradex, which delivers it to the buyer's procurement system so they can reconcile receipt against their PO.

Can invoices be sent via Tradex with complete PO and shipment detail?

Yes. iWeb extracts invoice data from your ERP, enriches it with PO and ASN references, and formats it as a Tradex invoice message. Tradex delivers the invoice to the buyer with all the data they need for three-way-match validation (PO line, shipment detail, invoice amount and terms).

How are contract pricing changes rolled out to buyers?

When a buyer contract is renegotiated, the pricing tier and terms are updated in Tradex and your ERP pricing tables in parallel. iWeb ensures both systems stay in sync. New POs use the updated pricing; existing orders continue on their original terms. Changes are tracked so you can audit what pricing each buyer received.

What approval workflows can iWeb enforce on incoming POs?

iWeb can route POs for approval based on buyer, total value, cost centre, delivery date or contract exception. Orders that pass validation flow straight through to fulfillment. Approval workflows are named and monitored so finance teams know which approvers need to act and can escalate stuck orders.

What happens if an ASN or invoice fails to deliver to the buyer?

iWeb monitors all outbound Tradex messages. If an ASN or invoice fails to deliver, the exception is logged with full details (buyer, PO, reason). iWeb can retry or escalate the issue, and you are notified so the buyer does not go silent waiting for shipment confirmation or invoice data.

How does iWeb handle Tradex credential rotation and API version upgrades?

iWeb manages Tradex API keys, tokens and version compatibility as part of the integration layer. When Tradex releases format changes or new buyer requirements, iWeb adapts the mapping so EDI flows do not break. Credential rotation is handled without manual intervention or downtime.

Can iWeb integrate Tradex with multiple ERPs or order systems?

Yes. iWeb maps Tradex EDI flows to your ERP, OMS or custom order system. If you have multiple operational systems, iWeb can route orders to the correct destination (e.g. direct fulfillment vs. drop-ship via a partner ERP) and ensure acknowledgements and invoices are consistent.

How are exception queues monitored and who is responsible for resolving them?

iWeb sets up named exception queues (e.g. pricing mismatch, validation error, approval pending) with clear ownership and SLA targets. Dashboards show which orders are stuck, why, and who needs to act. Escalation paths are defined so exceptions do not languish without resolution.

What data do buyers see in a Tradex punchout session?

Tradex displays buyer-specific product selections, pricing tiers, inventory availability and contract terms during punchout. iWeb ensures the punchout catalog reflects your current product data, buyer pricing and contract discounts so buyers see accurate information when they shop.

How does iWeb ensure that payment terms in the invoice match the contract?

iWeb retrieves negotiated payment terms (discount periods, net days, special terms) from the buyer contract in Tradex and ensures the invoice reflects them. Buyers can automate payment matching because the invoice data is complete and accurate.

Can iWeb handle split or partial shipments and ASN reporting?

Yes. iWeb can map partial shipments and split ASNs to Tradex, so buyers see which lines are being fulfilled now and which are pending. ASN data includes quantities, tracking and delivery dates, allowing buyers to reconcile receipt accurately.
