The verdict in three sentences
An EDI gateway connected to your ERP automates the exchange of orders, shipping notices and invoices with large retailers, in EDIFACT formats. In 2026 in Singapore, budget 15,000 to 35,000 EUR and 6 to 10 weeks depending on the number of partners and messages. Beyond the 30 hours of data entry saved per month, EDI is often a condition for being listed with major buyers.
What an EDI gateway costs in 2026
Pricing depends on the number of trading partners (each has its specifics), the number of message types and the depth of ERP integration.
| EDI scope | Partners / messages | Timeline | 2026 price (EUR) |
|---|---|---|---|
| Starter | 1-2 retailers, orders + invoices | 6-7 weeks | 15,000 - 20,000 |
| Standard | 3-5 retailers, + shipping notice | 7-9 weeks | 20,000 - 28,000 |
| Advanced | 6+ retailers, all messages, WMS | 9-10 weeks | 28,000 - 35,000 |
| Multi-flow international | + US/EU formats, multiple portals | 10-14 weeks | 35,000 - 55,000 |
Add a recurring cost of 150 to 600 EUR/month for the value-added network (VAN) or EDI platform subscription, plus maintenance of 2,000 to 5,000 EUR/year.
Formats, mapping and e-invoicing compliance
Each retailer imposes its variants; per-partner mapping is the most time-consuming item. E-invoicing reinforces the value of EDI in 2026.
| Element | 2026 standard | Impact |
|---|---|---|
| Main format | EDIFACT (ORDERS, DESADV, INVOIC) | Baseline |
| Per-partner mapping | 1,500 - 3,000 EUR / retailer | Cost multiplier |
| E-invoicing | Interoperability / structured invoice | +2,000 - 5,000 EUR |
| Acknowledgement | Mandatory CONTRL | Standard included |
| Logging | Full flow traceability | Standard included |
| Rejects and alerts | Retry queue + notification | +2,000 EUR |
Per-retailer mapping explains why the price rises with the number of partners: each retailer has its own item codes, date rules and mandatory segments.
Mini case study
Sophie runs a food distributor in Singapore that supplies 4 large retail chains. A two-person team manually re-enters EDI orders received via a web portal into the ERP: about 30 hours per month, with recurring quantity errors.
Sophie invests 24,000 EUR in an EDI gateway linked to her ERP, delivered in 8 weeks, covering ORDERS, DESADV and INVOIC for the 4 retailers. Gain: 30 h/month x 12 = 360 hours/year, i.e. 10,800 EUR/year at a loaded cost of 30 EUR/h, plus the disappearance of logistics penalties (around 5,000 EUR/year of quantity disputes). Payback in under 18 months, before counting the retained listing.

FAQ
Is EDI mandatory to work with large retailers?
In practice, yes: most large chains require EDI for supplier listing. Without EDI, you are penalised or dropped from many tenders.
What is the difference between EDI and e-invoicing?
EDI exchanges several message types (orders, notices, invoices) between systems. E-invoicing reform focuses on invoices; a modern EDI gateway handles both interoperably.
Why does the price rise with the number of retailers?
Each retailer imposes its own mapping (codes, segments, rules). Budget 1,500 to 3,000 EUR of configuration per additional partner.
Do we need a VAN or can we use AS2?
Both exist. A VAN charges a monthly subscription; AS2 is a direct exchange often included. The choice depends on your partners' requirements.
How long to pay off the gateway?
For a distributor saving 20 to 35 hours/month and avoiding logistics penalties, payback is between 14 and 22 months, beyond keeping the listing.
