B2B ordering system: what it is, how it differs from a B2B store, and what happens to your reps
"B2B ordering system" covers three different things, and vendors use the term for whichever one they sell: the ordering portal, the full B2B store, and back-office order management. If you're a wholesaler trying to get orders off the phone, you're choosing between the first two. This guide explains the difference, what either one does to your sales reps, and what the options cost.
"B2B ordering system" covers three different things, and vendors use the term for whichever one they sell. There's the ordering portal — a login where your existing customers place orders. There's the full B2B store — the portal plus the public catalog, the rep tools and the customer management around it. And there's order management software — the back-office system that routes and fulfils orders from every channel, which is a different product entirely.
If you're a wholesaler, distributor or manufacturer trying to get orders off the phone, you're choosing between the first two. This guide explains the difference, what either one does to your sales reps — the question that actually decides whether it gets used — and what the options cost.
What a B2B ordering system does
Strip the marketing and it does four things:
- Lets a customer place an order without talking to anyone. At their price, with their minimums, on their terms.
- Makes repeat orders fast. From history, from a saved list, from a grid where sixty lines take two minutes.
- Gets the order into your system — the ERP, the accounting package, or the store itself if that's your record — without anyone retyping it.
- Keeps the people in the loop. The rep sees the order and gets the commission. You see the order that's over the credit limit before it ships.
The first three are what every vendor shows. The fourth is what decides whether the system survives contact with your sales team.
Ordering portal vs. B2B store
| Ordering portal | B2B store | |
|---|---|---|
| Who can see it | Existing customers, after login | Anyone sees the catalog; prices after login |
| What's on it | Order form, history, documents | Catalog, product pages, order form, history, documents, account |
| New customers | Come from somewhere else | Find your products in Google, request an account |
| Reps | Often an add-on, priced per seat | Usually part of the product: portfolio, orders, commission |
| Your brand | Sometimes on the vendor's subdomain | Your domain |
| Typical fit | You already have all the customers you want and just need them to stop calling | You want orders off the phone and new accounts finding you |
The honest summary: a portal is a B2B store without the front door. If you have 200 accounts and no intention of adding more, a portal is enough. If you'd like Google to bring you the 201st, you want the store — a public catalog where retailers find your products and the prices appear only when you've approved them.
Most products in this market are both and call themselves whichever sells. Check which one you're being shown.
What happens to the rep
This is the part the vendor pages skip, and it's where B2B ordering projects fail.
A rep's fear is simple: if the customer orders on a website, what am I for? Build the system around that fear and it gets ignored by the reps — who then tell their accounts to "just send me the order like before," and your ordering system becomes a login nobody uses.
Build it the other way around:
- The rep has a portfolio on the system. Their accounts, their orders, their numbers. They log in from a phone in the customer's back room, see the customer's price and the stock, and place the order there instead of on a notepad.
- Commission follows the account, not the channel. If the customer orders alone at 11 pm, the rep still earns on it. The system is working for the rep while they sleep; that's the pitch, and it's true.
- The routine order leaves the rep's day. The 40-SKU reorder that took a phone call and fifteen minutes of typing now takes the customer two minutes. The rep's day fills with the new product, the lapsed account and the shop that wants to try a line — which is the job.
We've watched this go both ways. Reps who got a portfolio and visible commission brought their accounts onto the system in weeks. Reps who got bypassed made sure it never worked. If a vendor can't show you the rep's screen and the commission rule, that's the answer about who the system was built for. (Here's ours.)
The features that matter, in order
- Price list per account — the customer's price, not a discount.
- Minimums and multiples — enforced in the cart.
- Reorder from history and an order grid for long orders.
- Net terms and credit limits — over-limit orders wait for approval.
- Rep portfolios with commissions — on every order the account places.
- Account approval — prices only for approved accounts.
- ERP connection or open API — orders out of the system, prices and stock in.
- Documents the customer can download in their portal — invoice, packing slip, status.
- Payments that fit a business — cards and terms, US sales tax where it applies.
"Shopping cart software" is what some vendors call item 3. A cart is one feature of an ordering system, not a product; if what you're being sold is a cart, the other eight are missing.
What it costs
What the platforms that publish prices charge, from their own pricing pages as of October 2026. For an ordering system the question is what happens when the orders actually move online — the third column:
| Platform | Entry price (published) | What makes it grow |
|---|---|---|
| OrderEase | From US$ 500/mo + setup fee | Order volume, order sources, systems connected |
| Orderspace | US$ 65/mo (no reps) to US$ 185 (20 reps) | Reps per tier |
| B2B Wave | €320/mo | 10 users, 20 price lists included; more is a quote |
| SparkLayer (on Shopify) | Free to US$ 299/mo, Enterprise from US$ 499 | Order caps: 5, 50, 100, 150 per month |
| BigCommerce | US$ 39 to US$ 1,499+/mo | Sales caps; fees on sales above them |
| NuORDER, RepSpark, MarketTime | Not published | — |
| VentasxMayor | US$ 99.00/mo, flat | Nothing. No order caps, no per-rep fees, no commissions, no contract |
From each vendor's pricing page, read October 14, 2026.
Look at SparkLayer's column: the plan is priced by how many orders your customers place a month. For a system whose entire purpose is to move orders online, a cap on orders is the model working against the product. Per-rep pricing has the same problem one step earlier: it charges you for putting the team on it. We charge a flat fee because an ordering system should get cheaper per order the more it's used, not more expensive.
Order management software is something else
If what you need is to route orders from Amazon, your website, EDI and your reps into one place and out to warehouses, that's order management (OMS) — Brightpearl, Cin7, Acumatica, IBM Sterling and the like. It sits behind the store, not in front of the customer. A distributor usually needs the B2B store first and an OMS only when there are several channels and several warehouses to reconcile. Don't buy the second to solve the first.
Frequently asked questions
What is a B2B ordering system?+
Software that lets your business customers place orders on their own — at their price, with their minimums, on their terms — and gets those orders into your system without retyping, while your reps keep their portfolios and commissions. Vendors use the term for ordering portals, full B2B stores and sometimes back-office order management; make sure which one you're looking at.
What's the difference between a B2B ordering portal and a B2B store?+
A portal is for customers you already have: login, order, history. A store adds a public catalog so new retailers find your products in Google, with prices visible only after you approve the account. Most products are both.
Will a B2B ordering system replace my sales reps?+
It shouldn't, and the ones that try get ignored. The good ones give reps a portfolio, let them order on behalf of accounts from a phone, and pay commission on every order the account places — including the ones the customer places alone.
How much does a B2B ordering system cost?+
Published entry prices run from about US$ 39 to US$ 500+ a month, and most grow with reps, orders or sales. VentasxMayor is US$ 99.00 a month flat, with no order caps and no per-rep fees.
Does it connect to my ERP?+
On most platforms the connector is scoped and quoted separately; ask before you sign. VentasxMayor has an open REST API with a token, so your ERP or accounting system can read orders and push prices and stock.
Is "B2B shopping cart software" the same thing?+
A cart is one feature of an ordering system — the grid where the customer builds the order. If a product is only a cart, the price lists, terms, reps and ERP connection are missing.
