T-Sets | ANSI X12 810

Electronic Data Interchange (EDI) continues to be a vital part of how businesses communicate with each other. The market has been growing at a CAGR of 9.8% since 2022, and is slated to continue that track record all the way to 2030.1

But while EDI has been around for decades, there is still a lot on the subject that businesses should continue to learn about. An example is the American National Standards Institute X12 (ANSI X12), one of the key standards within EDI. Considering its wide usage across a variety of industries and company sizes, it’s critical to understand to make the most of how your business addresses EDI.

That’s why today, of the multiple messages within this standard, we’ll be covering the ANSI X12 810 transaction set (T-Set.) With this guide, we can help you understand everything you need to know about this T-Set, including:

  • The ANSI X12 810 message’s main uses.
  • How a typical ANSI X12 810 message is structured.
  • The steps that go behind processing an ANSI X12 810 message.

What is the ANSI X12 810 T-Set?

The ANSI X12 810 T-set, often referred to as the Invoice Transaction Set, serves as a standard for sending invoice data between businesses. 

Due to its capabilities in facilitating the exchange of sales information, this T-Set is used in multiple industries, from Retail to Transportation & Logistics. If you want to improve how your organisation carries out B2B transactions, the ANSI X12 810 T-set is an essential tool for efficient, reliable communication.

Benefits and drawbacks of the ANSI X12 810 message

Like all technologies, the ANSI X12 810 T-set comes with its strengths and limitations. However, the advantages greatly outweigh the challenges.

Key benefits of the ANSI X12 810 T-set include:

  1. Efficiency improvement: Automating the invoice process reduces time-consuming manual tasks, allowing you to direct more of your efforts on to other critical business operations.
  2. Data accuracy: Automation minimises human errors, ensuring the data accuracy of your invoices.
  3. Payment cycle acceleration: Digital invoice processing reduces payment cycle duration, enhancing cash flow.

The main challenge associated with the ANSI X12 810 is its complexity. While its automation capabilities save a lot of errors in communication, the actual data input needs to be accurate to prevent the message from being rejected. 

The best way of addressing this is through considering external solutions and expert EDI partners that can seamlessly integrate with your business operations.

How is an ANSI X12 810 T-Set structured?

A typical ANSI X12 810 message follows this structure:

ISA*…*  // Interchange Control Header
GS*IN*SellerDept*BuyerDept*YYMMDD*HHMM*1*X*004010
ST*810*0001
BIG*YYMMDD*InvoiceNo*YYMMDD*PONo
N1*ST*ABC Company*9*123456789
ITD*05*3*1.5**15**45
DTM*011*YYMMDD
IT1**1*EA*10**UP*012345678905
TDS*1000
CAD*SCAC*ProNo*BOL*RefNo
SE*10*0001
GE*1*1
IEA*1*000000001

Now let’s break down each segment and the purpose they serve within the message:

SegmentDescriptionPurpose
ISAInterchange Control Header: Begins the interchangeThe start of the interchange
GSFunctional Group HeaderStart the Invoice group
STTransaction Set Header: Begins the transaction setStart of the Invoice Transaction Set
BIGBeginning Segment for Invoice TransactionIndicates the invoice and purchase order dates and numbers
N1Name: Identifies a party by organisation, name, and codeIdentifies the buyer ‘ABC Company’
ITDTerms of Sale or Deferred TermsSpecifies the payment terms
DTMDate/Time Reference: Provides key datesIndicates the invoice date
IT1Baseline Item Data (Invoice): Provides details on each invoiced itemDetails of the item invoiced
TDSTotal Monetary Value SummaryIndicates the total invoice is for $1,000
CADCarrier Details (Invoice): Provides the transportation detailsSpecifies the shipment details
SETransaction Set Trailer: Marks the end of the transaction setEnd of the Invoice Transaction Set
GEFunctional Group Trailer: Marks the end of a functional groupEnd of the Invoice group
IEAInterchange Control Trailer: Marks the end of an interchangeThe end of the interchange

How an ANSI X12 810 T-Set is processed

Here are the steps for processing the ANSI X12 810 T-set:

  1. EDI document creation: Prepare and send the EDI document, such as the Invoice (EDI 810), to the trading partner.
  2. EDI document reception and processing: The receiving system accepts the incoming EDI document and checks for errors.
  3. Invoice generation: If the document passes the checks, the receiving system generates the invoice.
  4. Invoice transmission: The invoice is sent to the original sender, notifying them about its receipt and processing status.
  5. Error handling: If an error indicates rejection, the original sender then corrects the mistake and resends the document — effectively restarting the process.

EDI standard equivalents

It’s also worth knowing the equivalents of the ANSI X12 810 message in other major EDI standards. Having this knowledge helps your business see greater interoperability (across various regions and industries), integrations with other systems, and in meeting compliance regulations.

Here are examples of how the ANSI X12 810 T-Set translates into other standards:
