B2B Order Portal: Features & Operating Models Compared

A B2B order portal is the digital ordering channel for your business customers: they see their negotiated prices, add products to the cart, and place orders themselves — around the clock, no phone call, no email chain. From the outside it looks like a regular online shop, with categories and a checkout. The difference isn't in the frontend but underneath: at the center are not anonymous purchases but maintained customer relationships — with custom prices per customer group, order history, and approval workflows.

What makes a B2B order portal

Four capabilities carry the day-to-day work of an order portal — without them it's just a shop with a login:

Customer-specific pricing. Every buyer sees the prices that apply to them: custom price catalogs per customer group, tiered pricing above certain quantities, agreed payment terms. That logic has to live in the system — not in the head of your sales rep.

Order lists and quick ordering. Buyers usually know exactly what they need. Type in the article number, enter the quantity, done — instead of clicking through categories. Industrial portals show how it's done: machinery manufacturers like RENK or Röchling run after-sales portals where dealers and factory service providers reorder spare parts in minutes.

Reordering from history. The most common B2B order is the identical repeat: same filters, same consumables, last month like this month. One click on the last order replaces the call to field sales.

Approvals instead of free-for-all. Who is allowed to order? New customers enter the portal by invitation or registration with approval — sales keeps control over the customer circle without having to sign off on every single order.

Three ways to run an order portal

There are three fundamentally different operating models for the same goal — and which one you choose determines cost, speed, and effort more than any feature list.

Classic: run a shop system yourself. Shopware, WooCommerce & Co. on your own hosting or a rented server: the system is your property, all possibilities are yours — and so are all obligations. Setup, B2B extensions, updates, security, maintenance sit with you or your agency. Ongoing costs typically in the triple digits per month plus support.

Custom: an agency builds your portal. For special cases no standard product covers: encapsulated ERP processes, industrial configurators. Entry price from a mid five-figure one-time sum plus continued development — powerful, but a construction project with permanent follow-up.

Modern: a SaaS platform as a service. The order portal runs ready-made in the cloud: you set up products, prices, and customers — operations, hosting, security, and updates are part of the service. The frontend is a full-fledged shop with categories, search, and cart; your team maintains content instead of systems. New requirements like the E-Rechnung mandate from 2027 (Germany's e-invoicing requirement) arrive automatically via update, not as a project at your service provider.

Which model fits you?

Three honest rules of thumb from customer and industry conversations:

You have IT and established processes — say, a Shopware system with a connected ERP that runs and is maintained: stay classic. Migrating would cost more than what you have.

You have a special requirement no standard knows — deep ERP interlocking, configurators, industrial cutting: custom development isn't a luxury then, it's the only way to map your business. But expect project character, permanently.

You want to digitalize your B2B sales without founding an IT department — by far the most common case in the German Mittelstand: SaaS is built for exactly that. Instead of building and maintaining a system, you rent the result.

What makes Kontorly an order portal

Kontorly is a German B2B e-commerce platform (SaaS) for online shops with tiered pricing, customer groups, and direct ordering by business customers. Made in Germany, from Hamburg. For your customers it's a shop: categories, search, cart, checkout, order history — mobile and at the desk. For you it's a service: tiered pricing, customer groups, ZUGFeRD E-Rechnungen, and German taxes are included from day one, you maintain pricing in minutes, and operations run in the background while your customers order around the clock.

Whether a SaaS order portal fits your business is fastest to see in a demo — your catalog, your pricing, your questions.

FAQ

Is an order portal the same thing as an online shop?

From the outside, yes — categories, product pages, cart. The difference lies in the processes behind it: contract-specific prices, approvals, order history, E-Rechnungen. In B2B, the portal is the standard architecture for customer shops.

What does a B2B order portal cost?

Depends on the operating model: SaaS platforms start at around €250 per month, classic systems cost license plus hosting plus support, custom builds start at €30,000. The full calculation with an example is here.

How long does it take to set up a B2B order portal?

Depends on the operating model: a SaaS platform is up in days — set up products, prices, invite customers, done. Classic shop systems take weeks to months, custom agency builds months. The time difference is part of the cost calculation.
