Government and public sector
Government and Public Sector EDI and API Integration
Orders and invoices that meet each government buyer's submission rules
Government buyers specify exactly how suppliers receive orders and submit invoices and receiving documents, often through their own portals or electronic invoicing systems. Public agencies, for their part, exchange files with banks, vendors and other agencies. ECOM connects those exchanges to the ERP and finance systems behind them, so documents are produced once and submitted the way each buyer requires.

- Who we help
- Suppliers to federal, state and local government, and the public agencies and authorities that buy, pay and report.
- What we connect
- Orders, receiving documents and invoices between your ERP and each government buyer's submission system, and agency files with banks, vendors and other agencies.
- Problems we solve
- Each agency specifies its own submission method, rejected invoices delay payment, and contract clauses set the rules.
- Even without EDI
- Government buyers often use their own web submission systems, portals, APIs or file uploads rather than EDI. ECOM works with those routes as well as EDI.
What is government EDI?
Government EDI is the electronic exchange of procurement, invoicing, payment and program data between government organizations and their suppliers, banks and partner agencies. Suppliers commonly exchange ANSI X12 purchase orders (850), ship notices (856) and invoices (810), or submit the same data through a government portal or file upload. Agencies also exchange payment files and program data in formats set by the receiving organization.
Who you connect with
Who a government supplier or agency exchanges data with
Suppliers and agencies see the same exchange from opposite sides. The first group is submission systems; the second is the agencies' own partners.

Two sides of the exchange
Government suppliers and public agencies need different integrations
Suppliers submit documents to government systems. Agencies exchange files with banks, vendors and other agencies. Military-exchange retailer guides do not replace the broader federal procurement coverage below.
-
Suppliers to federal agencies
Contractors submitting invoices and receiving documents under federal contracts.
- How it runs
- The contract names the submission system. Defense contracts name a DoD electronic invoicing system, and many civilian agencies enroll vendors in Treasury's Invoice Processing Platform (IPP). ECOM is not an agency system and holds no agency authorization; it prepares the data your team submits or sends as the agency requires.
- Systems
- ERP, the agency's submission system.
- Typical problem
- Documents must be submitted through the named system with the right fields, and rejections delay payment.
Source note. For IPP, the agency starts a vendor's enrollment. SAM registration remains a separate requirement. Confirm the current steps with your contracting office.
-
Suppliers to state and local government
Suppliers to cities, counties, school districts and state agencies.
- How it runs
- Purchase orders and invoices follow the agency's e-procurement portal, or are exchanged as files where the agency supports them.
- Documents
- Systems
- ERP, agency e-procurement systems.
- Typical problem
- Each jurisdiction has its own portal and rules, so there is no single format to build once.
-
Military exchange and commissary retail
Suppliers selling retail goods to military exchanges and commissaries.
- How it runs
- Purchase orders, ship notices and invoices follow each exchange's vendor program, similar to other retailers.
- Systems
- ERP, retailer vendor portals.
- Typical problem
- Exchange programs have their own requirements, which are separate from federal contract submission systems.
-
Public agencies and authorities
Agencies and authorities exchanging files with banks, vendors and other agencies.
- How it runs
- Payment, vendor and reporting files move over secure, monitored connections, with remittance and acknowledgments tracked.
- Systems
- Agency finance and case systems, bank connections.
- Typical problem
- Files must be delivered reliably, and exceptions must be visible to the right team.
How to read this page: a standard or system named here shows where a requirement is published or what ECOM can connect. It does not mean ECOM has a verified partnership with any named company, and your own contracts and partners define the final requirements.
Who it's for
Different roles, different workflows
-
Suppliers to federal agencies and the military
Your contract names how invoices and receiving documents are submitted, and orders may arrive electronically or through a portal. Marking, packaging and data-handling clauses apply alongside.
-
Suppliers to state and local government
States, counties, cities and school districts buy through their own eProcurement systems, each with its own supplier registration and invoice submission rules.
-
Public agencies and authorities
Agencies exchange payment, remittance and program files with banks, vendors and other agencies, and need secure, logged transfers with clear ownership.
How the workflow runs
From government order to accepted invoice and payment
Government buyers often separate ordering, receiving and invoicing into different systems. The supplier's job is to send the same data consistently to each.
- Agency buyer→Your company 850 Order or delivery order Contract, line items and ship-to.
- Your company→Agency buyer 855 Acknowledgment Where the buyer requires one.
- Your company→Government system 856 Shipment or receiving document Submitted as the contract requires.
- Your company→Government system 810 Invoice Contract and line references.
- Government system→Your company 824 Status or rejection Accepted, rejected or returned.
- Agency buyer→Your company 820 Payment and remittance What was paid against which invoices.
- 01
Receive the order
Orders arrive by EDI, portal or email and are loaded into the ERP with the contract and line references the invoice will need.
- 02
Ship and document
Shipment or receiving documents are produced from shipping data and submitted the way the contract requires.
- 03
Submit the invoice
Invoices carry contract and line references and are sent as EDI, file upload or portal entry, depending on the buyer.
- 04
Track acceptance
Rejections and returned invoices are captured with their reason so they can be corrected quickly.
- 05
Reconcile payment
Remittance is matched to invoices so receivables reflect what was actually paid.
Beyond EDI
Every way government documents move, kept consistent with your records
A supplier may enter an invoice in a web system, send an EDI file to another and upload a receiving report to a third. ECOM prepares the same data for each route.

Challenges
Integration challenges in government and public sector
A different system for every buyer
Federal, state and local buyers each run their own procurement and invoicing systems with different rules.
Rejections for missing references
Invoices without the exact contract, order or line references are returned, delaying payment.
Manual portal entry
Re-keying invoices and receiving documents into portals takes time and introduces errors.
Data-handling obligations
Contracts may set rules for how data is transmitted, stored and accessed.

Frequently asked questions
Can government invoices be submitted by EDI?
Many government invoicing systems accept EDI files as well as portal entry or file upload. The contract and the buyer's system define which methods are accepted.
Is ECOM authorized or certified for government cloud use?
This page makes no government authorization claim. ECOM's current security attestations are listed on its security page, and your contract's requirements are reviewed during scoping.
Does ECOM provide government procurement software?
No. ECOM integrates documents and data between your systems and the systems government buyers specify.
Do military exchanges use EDI?
Yes. Military exchange retailers run supplier EDI programs for orders, ship notices and invoices, like other retailers.
