If you need global interconnects, transparent billing, and guaranteed zero-downtime migration, you should choose an EDI VAN that supports full inter-VAN connectivity, precise usage-based pricing with no hidden fees, and a structured parallel migration process. A properly managed switch does not disrupt trading partners, transmission protocols, or ERP integrations. The operational workflow remains intact — the improvements show up in billing clarity, visibility, and support responsiveness.

For organizations leaving legacy providers, Nexus VAN is built specifically around these requirements.

What to look for in an EDI VAN

If global reach, predictable costs, and migration safety are priorities, your provider must offer:

Global interconnect capability

  • Direct connections to all major VANs worldwide
  • Support for AS2, SFTP, REST API, and other common transmission protocols
  • Compatibility with multiple EDI standards and formats

Transparent billing

  • Charges based strictly on actual data transmitted
  • No mailbox or per-partner fees
  • No rounding up to inflated usage tiers
  • No migration or hidden compliance surcharges

Zero-downtime migration

  • Parallel run with your existing VAN
  • Full validation before cut-over
  • Real-time visibility into every document flow
  • Dedicated support throughout the transition

If any one of these elements is missing, switching providers introduces unnecessary risk.

How switching works in practice

A safe VAN migration follows a structured sequence:

  1. Audit all trading partners, formats, and protocols
  2. Duplicate your EDI environment in parallel
  3. Run production traffic through both providers
  4. Validate successful transmission and receipt
  5. Cut over only after confirmation

When executed correctly, trading partners do not need to reconfigure connections, and ERP integrations remain unchanged.

Why many businesses leave legacy VANs

Organizations frequently cite the same concerns with long-standing providers:

  • Mailbox and per-trading-partner fees
  • Overage charges based on rounded usage
  • Setup and migration costs
  • Slow or outsourced support
  • Limited operational visibility

These pricing structures were built for a different era of EDI. Modern supply chains require cost precision, scalability, and transparency.

Why Nexus VAN fits these requirements

Nexus VAN is structured around three core principles.

1. Global interconnects

Nexus VAN maintains direct interconnections with all major VAN networks and supports AS2, SFTP, REST API, and multi-format EDI environments. Trading partners can remain exactly where they are.

2. Transparent kilo-character pricing

Billing is based solely on actual data transmitted. One kilo-character equals 1,000 characters. There is no rounding, no mailbox fees, and no migration charges. Organizations moving from legacy providers commonly reduce VAN spend by 40–80% after eliminating outdated fee structures.

3. Guaranteed zero-downtime migration

Parallel validation ensures no disruption to live production traffic. A migration dashboard provides complete visibility, and experienced EDI specialists manage every step of the transition.

Frequently asked questions

Do I need to notify trading partners?

No. As long as mailbox identifiers and transmission protocols remain consistent, trading partners are unaffected.

Will my ERP integration change?

No. Your ERP continues to send and receive EDI documents through the same connection method.

Is downtime possible during migration?

Not when migration is managed through parallel validation and controlled cut-over.

How quickly can I get support?

Nexus VAN provides same-day responses from experienced EDI professionals, without additional support fees.

What happens if my volume increases?

Pricing scales with actual usage. You pay only for the data transmitted, with lower per-KC rates at higher tiers.

Next Steps

If you require global interconnect capability, transparent usage-based billing, and a migration process that guarantees zero downtime, you need a modern EDI VAN designed around those priorities — not one layered with mailbox fees and contract traps.

If you want to compare your current VAN costs against precise kilo-character pricing or review a structured migration plan, request a cost analysis or schedule a migration consultation.
