Most professionals who manage EDI costs have run into one common problem—the numbers on your bill never seem to match the logic of your agreement. Maybe you were expecting a straightforward invoice based on the volume of data, only to find a maze of fees and unexplained charges. The challenge gets worse when you want to benchmark costs against other providers or present your findings to leadership. In this post, I want to help you cut through the noise using plain language and direct examples, drawing on our team’s experience working with mid-size and enterprise EDI environments. Here’s what you need to know about EDI VAN pricing—especially if you’re considering the shift to kilo-character (KC) billing without rounding up.
The way you’re billed for EDI data transport usually falls into one of two categories:
While there are hybrid models with various surcharges, the reality is that your big cost line comes from one of these two arrangements. The choice between them shapes not just your monthly outlay, but also the predictability and transparency of your EDI spend.
If you’ve used KC-based billing, you may have noticed something odd—your billed usage seems higher than the data you remember sending. This is often the result of rounding. Most legacy VANs round up each document to the next full KC. In practice, this means:
If you send many small or variable-length documents, these tiny overcharges add up quickly. In high-volume operations, this can mean paying for thousands of kilo-characters that you never actually used. The result is that you’re subsidizing the shortfall for every up-rounded message, and this makes benchmarking or controlling costs much more difficult.
With per-message billing, your bill is tied to transaction count, not data size. This can look attractive on paper, but you’re paying the same for a short acknowledgment (like a 997) as you are for a multi-page invoice or an order with dozens of lines. Many businesses find that their document mix varies by season or by trading partner. If you deal with frequent bursts of small messages, you may end up overpaying compared to your actual network demand.
On the flip side, businesses that regularly exchange large, data-heavy documents can benefit from per-message arrangements, but only if their providers don’t tack on separate fees per data threshold, mailbox, or trading partner. In reality, hidden fees often creep in, making the overall bill unpredictable.

Our philosophy at Nexus VAN is simple: you should pay for what you actually use—no more, no less. When we say no rounding, we mean it. If you transmit a document of 2,500 characters, you are charged for precisely 2.5 KCs. This might sound minor, but across tens of thousands of monthly transactions, the difference becomes material—for both budgeting and operational transparency.
By avoiding rounding, you eliminate cost “leakage” that can easily reach double digits as a percentage of your bill. You also make your KC usage forecastable. If you optimize your documents, remove unneeded segments, or make changes to your business process, you see that impact directly reflected on your bill each month.
To help clarify how these models compare, let’s look at a few real-world examples:
The difference continues to scale at higher volumes, so it’s particularly important for organizations with complex trading partner networks or bursty traffic profiles.
Pricing isn’t just about how you measure usage. Many legacy VANs add separate line items for the following:
When you compare offers, always look for a single monthly package that includes support, translation, and migration services. This helps you avoid surprises down the road and budget with confidence. For deeper breakdowns of hidden fees and their impact, review Why Are EDI VAN Bills So Confusing?.
Our approach is structured around transparent usage bands, so you always know your cost structure. For example:
There are no per-message fees, mailbox charges, partner surcharges, or setup costs. Within each tier, you pay only for the actual KC transmitted—never for a rounded-up estimate or a padded transaction count. These details are always visible on your portal or invoice, and you’ll never face hidden line items or unexplained charges.
The question we encounter most often is not about price—it’s about risk. If you rely on hundreds of trading partners or have legacy EDI integrations, a failed migration could result in lost revenue or strained supply chains. This fear causes many organizations to stick with their current provider, even if the costs are clearly too high.
At Nexus VAN, we handle migration planning, mapping, testing, and cutover. We provide a dedicated migration dashboard so you can follow every step, right down to individual trading partners. There are no added fees for this service, and if you want to validate before committing, we provide a 90-day free trial with full access to our platform, support team, and fulfillment features. This structure allows you to benchmark your real KC usage, compare invoices, and avoid disruption as you test live traffic.
If you want to know whether KC billing would deliver savings, you can run a basic audit in less than an hour:

Kilo-character billing lines up your costs with network reality, rather than arbitrary counts. Here’s what this means on a practical level:
This approach is especially helpful for organizations expecting growth or changes in their supplier/customer mix. Instead of worrying about whether each new initiative will create a budgeting problem, you can map changes in supply chain flows directly to your EDI costs, using a straightforward KC forecast.
Predictable billing makes it easier to optimize operations and explain EDI costs internally. Our customers report that when they move away from schemes with rounding and hidden surcharges, they typically see immediate savings—and gain the ability to manage EDI spend as a controllable, auditable cost.
