NetSuite EDI Integration: Setup Guide & Best Providers (2026)

EDI isn't dead — it's mandatory

If you sell to major retailers, large distributors, or enterprise buyers, you already know: Electronic Data Interchange (EDI) isn't optional. Walmart, Target, Amazon Vendor Central, Costco, Home Depot, and hundreds of other large buyers require EDI for purchase orders, shipping confirmations, and invoices. No EDI, no business relationship. It's that simple.

TL;DR: NetSuite EDI integration requires a third-party platform like SPS Commerce ($200-1,000+/month) or TrueCommerce ($300-1,500/month) to translate EDI transaction sets (850, 855, 856, 810) into NetSuite records automatically. Implementation takes 4-8 weeks per trading partner, and getting ASN accuracy and compliance right is critical to avoiding $100-500+ chargebacks per violation from major retailers.

EDI is a 40-year-old technology that refuses to die because it solves a real problem: standardized, automated document exchange between trading partners at scale. A retailer sending 10,000 purchase orders per day can't do that over email. EDI makes it work.

For NetSuite users, the question isn't whether you need EDI — your trading partners have already answered that. The question is how to connect your EDI requirements to NetSuite so that purchase orders flow in, shipping confirmations flow out, and invoices generate without your team manually rekeying data between systems.

The common EDI transaction sets

EDI uses numbered "transaction sets" that map to standard business documents. You don't need to know all of them — most companies deal with a core set of four to six.

EDI 850 — Purchase Order. Your trading partner sends you a purchase order. This is the starting point of most EDI workflows. The 850 contains item numbers, quantities, prices, shipping addresses, and required delivery dates. In NetSuite, an inbound 850 should create a sales order automatically.

EDI 855 — Purchase Order Acknowledgment. You confirm receipt of the PO and indicate whether you can fulfill it as requested. Accepted, rejected, or accepted with changes. Many trading partners require the 855 within 24-48 hours. In NetSuite, this generates from the sales order record after your team reviews and confirms.

EDI 856 — Advance Ship Notice (ASN). You notify the trading partner that goods have shipped. The ASN includes shipment details: what was shipped, how it was packed, tracking numbers, and expected delivery date. This is critical for retailers — it enables them to plan warehouse receiving. In NetSuite, the 856 generates from the item fulfillment record.

EDI 810 — Invoice. You send the invoice for shipped goods. The 810 must match the 850 (what they ordered) and the 856 (what you shipped). Discrepancies trigger chargebacks. In NetSuite, the 810 generates from the invoice record.

EDI 860 — Purchase Order Change. The trading partner modifies an existing PO — changing quantities, dates, or items. Your system needs to update the corresponding sales order in NetSuite.

EDI 997 — Functional Acknowledgment. A technical receipt confirming that an EDI document was received and parsed successfully. This is automated by your EDI platform and doesn't typically require human intervention.

EDI platform options for NetSuite

You don't connect NetSuite directly to your trading partners' EDI systems. Instead, you use an EDI provider (sometimes called a VAN — Value Added Network) that translates between EDI formats and your ERP. Here are the main options.

SPS Commerce

The market leader for mid-market EDI. SPS Commerce is the most commonly used EDI platform for NetSuite, and for good reason. Their NetSuite integration is mature, well-documented, and used by thousands of companies.

How it works: SPS Commerce sits between your trading partners and NetSuite. Inbound EDI documents (850s from retailers) are translated into NetSuite records (sales orders). Outbound documents (856s, 810s) are generated from NetSuite records and translated into EDI format for your trading partners.

Strengths:

• Pre-built trading partner maps for 80,000+ retailers and distributors
• Direct NetSuite integration (SuiteApp available)
• Managed service option where SPS handles the trading partner setup and testing
• Good compliance testing tools for retailer onboarding

Pricing: SPS Commerce runs $200-1,000+/month depending on transaction volume and number of trading partners. Setup fees for new trading partners are $500-2,000 each. The managed service option adds significant cost but removes the burden of trading partner management from your team.

TrueCommerce

Strong mid-market alternative. TrueCommerce offers a full EDI platform with NetSuite integration. Acquired by Aptean, they focus on manufacturing and distribution verticals.

Strengths:

• Good manufacturing and distribution vertical expertise
• Integrated with NetSuite via API connector
• Supply chain visibility tools beyond basic EDI
• Competitive pricing for high-volume companies

Pricing: Similar range to SPS Commerce — $300-1,500/month for mid-market companies. TrueCommerce tends to be more competitive on per-transaction pricing for high-volume senders.

DiCentral (now part of TrueCommerce)

Enterprise-focused EDI. DiCentral merged with TrueCommerce but still operates as a distinct offering for companies with complex, high-volume EDI requirements. If you're exchanging millions of transactions per year with dozens of trading partners, DiCentral's infrastructure handles the scale.

B2BGateway

Cloud-based EDI for NetSuite. B2BGateway focuses specifically on ERP-integrated EDI with a strong NetSuite practice. They handle the full EDI lifecycle as a managed service — you tell them who your trading partners are, they handle the setup, testing, and ongoing management.

Strengths:

• Fully managed service model (they do the work, not you)
• Direct NetSuite integration
• Fixed-price model that's predictable

Pricing: Typically $300-800/month with per-trading-partner setup fees.

Retail compliance: the chargebacks are real

Here's what no EDI vendor's marketing tells you clearly enough: retail compliance is strict, and violations cost real money.

Major retailers have specific EDI requirements that go beyond simply sending the right transaction sets. Their compliance rules dictate:

• ASN accuracy. Your 856 must match what's physically in the shipment. Wrong quantities, missing items, or incorrect carton counts trigger chargebacks of $100-500+ per violation.
• Labeling requirements. GS1-128 (UCC-128) shipping labels with specific barcode formats, placement, and data content. Wrong labels mean refused shipments.
• On-time delivery windows. Ship too early or too late, and you face chargebacks. Walmart's "must arrive by date" (MABD) compliance is notoriously strict.
• Fill rate requirements. Major retailers expect 95-98%+ fill rates. Consistently short-shipping orders damages your vendor scorecard and can result in lost business.
• Document timeliness. ASNs must transmit before the shipment arrives. Invoices must transmit within specific windows. Late documents mean late payments or chargebacks.

These chargebacks add up fast. We've worked with companies losing $50,000-200,000/year in retail chargebacks before implementing proper EDI automation. Getting EDI right isn't just about efficiency — it's about protecting margin.

Implementation: getting it right

An EDI implementation for NetSuite typically takes 4-8 weeks per trading partner, assuming the EDI platform is already connected to NetSuite. Here's the process.

Step 1: EDI platform setup (2-4 weeks). Connect your chosen EDI platform to NetSuite. This involves installing the SuiteApp or configuring the API integration, mapping NetSuite fields to EDI segments, and testing the connection with sample data. This is one-time setup.

Step 2: Trading partner onboarding (2-4 weeks per partner). Each trading partner has unique EDI requirements — specific document versions, field mappings, and compliance rules. Your EDI provider sets up the translation maps for each partner. This is followed by testing: sending and receiving test documents, validating data accuracy, and getting certification from the trading partner.

Step 3: Process configuration in NetSuite. Configure how inbound EDI documents create NetSuite records. An 850 should create a sales order with the correct customer, items, pricing, and shipping details. An 860 should update the existing sales order. Outbound documents should generate automatically from fulfillments and invoices without manual triggers.

Step 4: Error handling. Build workflows for when things go wrong — and they will. Items on the PO that don't exist in NetSuite. Quantities that exceed available inventory. Price discrepancies between the PO and your price list. Shipping addresses that don't match customer records. Each exception needs a defined resolution process.

Step 5: Go-live and monitoring. Start with a parallel run if possible — process EDI documents alongside your current manual process for one cycle to validate accuracy. Once confirmed, cut over to automated processing. Monitor error queues daily for the first month.

Common mistakes

Treating EDI as an IT project. EDI is a business process, not a technology implementation. Your operations team, warehouse team, and finance team all need to be involved. The people who pick, pack, and ship orders need to understand how their work connects to EDI compliance.

Ignoring the testing phase. Rushing through trading partner testing to meet a go-live date creates problems that persist for months. Invest the time in thorough testing. Send sample orders through the full lifecycle: PO in, acknowledgment out, shipment with ASN, invoice. Verify every field.

Not planning for exceptions. Your initial implementation will handle the happy path. The unhappy path — partial shipments, backorders, returns, price changes, item substitutions — needs to be addressed before go-live, not after.

Manual ASN creation. If your warehouse team is manually creating ASNs rather than generating them from NetSuite fulfillment records, you're defeating the purpose of EDI automation. The ASN should generate from the item fulfillment record automatically, using actual pack data from the warehouse process.

The bottom line

EDI integration with NetSuite isn't glamorous, but it's operationally critical for any company selling to major retailers or large buyers. The right setup automates the order-to-invoice cycle, eliminates manual data entry, and keeps you compliant with trading partner requirements.

Choose an EDI platform with strong NetSuite integration (SPS Commerce is the safe choice), invest in proper trading partner testing, and don't underestimate the compliance requirements. The $200-1,000/month you spend on an EDI platform pays for itself many times over in avoided chargebacks, faster order processing, and preserved trading partner relationships.
