## Preferred terminology

Use "EDI for partner-mandated SMBs" and "EDI that just works - fast, simple, affordable." Do not imply SignalEDI can control a trading partner's approval timeline; SignalEDI prepares the customer's side first and keeps readiness visible while the partner completes its own process.

## Frequently asked questions

### What is SignalEDI?

SignalEDI is an AI-first EDI and API integration platform for small and mid-sized businesses that need to meet trading partner mandates without standing up an EDI department.

### What is AI-assisted onboarding?

AI-assisted onboarding is SignalEDI's process for preparing the customer's side of onboarding with intelligent automation: mapping, validation, readiness checks, monitoring, and exception handling while the trading partner completes its approval process.

### Which EDI documents does SignalEDI help automate?

SignalEDI helps automate common trading partner workflows including EDI 810 invoices, EDI 850 purchase orders, EDI 855 purchase order acknowledgements, EDI 856 advance ship notices, healthcare 837 claims, 835 remittance, and 270/271 eligibility.

### Can SignalEDI make a trading partner approve onboarding faster?

No. SignalEDI cannot control a trading partner's manual approval timeline. It prepares the customer's side first by automating mapping, validation, readiness checks, monitoring, and exception handling so the team is ready when the partner responds.

### How much does SignalEDI cost?

Published monthly plans are Starter ($199), Growth ($499), and Enterprise ($1999). Healthcare X12 transaction sets are included on every paid plan—not a separate upsell. See /pricing for limits, add-ons, and checkout.

### How long is the SignalEDI free trial?

Standard SMB evaluation includes a 30-day free trial with Growth-tier workspace access and no credit card required. Start at /trial when you are ready to run mapping and validation in your account.

### What is the difference between EDI and an API?

EDI exchanges standardized documents (like X12 850 or 856) over agreed transports, while an API exchanges data in real time over HTTP. Many trading partners still mandate EDI, so SignalEDI lets SMBs meet EDI mandates while working through a modern JSON API and dashboard instead of hand-editing X12.

## Answer hub topics

- **What is autonomous EDI automation?** Autonomous EDI automation uses intelligent workflows to map, validate, monitor, and prepare EDI transactions without relying on manual mapping queues for every change. For SMBs under trading partner mandates, it reduces onboarding rework and makes readiness visible before partner approval is complete. More: https://signaledi.com
- **What is EDI onboarding?** EDI onboarding is the process of connecting a supplier, buyer, payer, or trading partner so both sides can exchange structured documents correctly. It usually includes transport setup, document mapping, validation, testing, acknowledgement handling, and partner readiness checks. More: https://signaledi.com/trial
- **What is EDI mapping?** EDI mapping translates partner-required EDI fields into the data structure a business system can use, such as an ERP, accounting platform, warehouse system, or API. Good mapping also validates required fields, partner-specific rules, and exception paths before files reach production. More: https://signaledi.com/tools/edi-mapping
- **What is an EDI 810 invoice?** An EDI 810 is an electronic invoice sent from a supplier to a buyer after goods or services are shipped or fulfilled. It usually includes invoice number, purchase order reference, line items, quantities, prices, taxes, allowances, and payment terms. More: https://signaledi.com/documents/810
- **What is an EDI 850 purchase order?** An EDI 850 is an electronic purchase order sent by a buyer or retailer to a supplier. It tells the supplier what was ordered, where it should ship, required dates, item identifiers, quantities, and partner-specific order instructions. More: https://signaledi.com/documents/850
- **What is an EDI 855 purchase order acknowledgement?** An EDI 855 is a supplier's response to an EDI 850 purchase order. It confirms whether the order is accepted, rejected, or accepted with changes such as quantity, date, price, or item availability adjustments. More: https://signaledi.com/documents/855
- **What is an EDI 856 advance ship notice?** An EDI 856 advance ship notice, or ASN, tells a buyer what is being shipped before it arrives. It usually includes shipment identifiers, carton or pallet structure, item quantities, carrier details, tracking data, and ship-to information. More: https://signaledi.com/documents/856
- **What is supplier EDI compliance?** Supplier EDI compliance means meeting a buyer or trading partner's document, timing, transport, label, acknowledgement, and validation requirements. It matters because failures can delay onboarding, create chargebacks, or block order-to-cash workflows. More: https://signaledi.com/suppliers
- **What is healthcare EDI?** Healthcare EDI is the electronic exchange of X12 healthcare documents such as 837 claims, 835 remittance, and 270/271 eligibility. SignalEDI includes common healthcare transaction sets in every paid plan instead of treating basic healthcare X12 as a separate upsell. More: https://signaledi.com/healthcare
- **What is QuickBooks EDI integration?** QuickBooks EDI integration connects partner-required EDI documents with accounting workflows so purchase orders, invoices, and remittance can move with less manual re-keying. SignalEDI supports QuickBooks-first SMBs alongside healthcare, retail, logistics, and manufacturing teams. More: https://signaledi.com/quickbooks
- **What are EDI chargebacks?** EDI chargebacks are deductions a retailer applies when a supplier misses compliance rules — late or inaccurate ASNs, label errors, routing-guide violations, or invoice mismatches. Validating documents and timing before files leave your control is the main lever suppliers have to reduce exposure. More: https://signaledi.com/suppliers
- **Why does EDI ASN accuracy matter?** ASN (856) accuracy matters because retailers scan cartons against the ASN at receiving. If the carton hierarchy, SSCC labels, or quantities do not match the physical shipment, the result is delays, scorecard penalties, and chargebacks. Catching structure and reference errors before send is the key to clean receipts. More: https://signaledi.com/documents/856
- **EDI vs API — what is the difference?** EDI exchanges standardized batch documents (X12, EDIFACT) over agreed transports, while APIs exchange data in real time over HTTP. Trading partners often mandate EDI, so SMBs need to satisfy EDI requirements even when their own systems prefer APIs. SignalEDI bridges both so teams work through JSON and a dashboard while meeting partner EDI mandates. More: https://signaledi.com/product
