TL;DR: Running B2B wholesale on Shopify without proper infrastructure means manual approvals, tax errors, unpaid invoices, and communication breakdowns. This guide covers the ten features that make up a complete B2B portal for EU merchants: from approval workflows and VAT validation to net terms, credit control, and localized communications.
A B2B portal sits between your Shopify storefront and your back office. It’s the system that decides who gets wholesale access, what tax rules apply, how orders are handled after checkout, and what customers see in their account. Without it, you’re relying on spreadsheets, email chains, and someone on your team who “just knows” which customers are approved.
That works for five accounts. It breaks at fifty. It’s a liability at five hundred.
For EU merchants specifically, the stakes are higher. VAT compliance isn’t optional. Reverse charge rules depend on validated tax numbers. Payment terms vary by market. And your German customers expect communications in German, not English. A proper B2B portal handles all of this systematically instead of hoping your team remembers the right process every time.
We’ve worked with dozens of Shopify merchants launching B2B channels. The same five problems come up almost every time:
Approval timing. Teams either rubber-stamp applications to avoid backlog or let them sit for days because nobody owns the review process. Both cost you: one in risk, the other in lost sales.
Tax errors. A VAT number gets validated at signup. Six months later, the company deregisters. You’re still treating them as tax-exempt. The tax authority sends you a letter. Nobody enjoys those letters.
Payment complexity. You offer net terms to ten customers. Now you’re tracking who owes what, sending invoices manually, chasing late payments over email, and hoping your spreadsheet is up to date. It isn’t.
Order data gaps. Your finance team receives a Shopify order and can’t create an invoice because there’s no company name, no VAT number, no PO reference. They email sales. Sales emails the customer. Three days wasted.
Communication breakdowns. The customer gets approved but never receives a notification. A net terms order comes in but the warehouse ships before the credit check. An address changes but nobody tells the finance team. Every handoff is a place where things fall apart.
Every B2B relationship starts with approval. The question is whether you do it manually for every application, or set rules that handle the routine cases automatically so your team focuses on exceptions.
Four modes work in practice:
The goal is getting to rule-based as soon as you’re comfortable. Manual review doesn’t scale, and slow approvals lose you customers who sign up with your competitor while waiting.
Checking a VAT number once at signup and never again is like checking a driver’s license once and assuming it’s valid forever. Companies deregister, merge, go bankrupt. Their tax status changes. Yours doesn’t, unless you keep checking.
A solid B2B portal validates VAT numbers via VIES at signup, then re-checks on a configurable interval (every 30, 60, or 90 days). When a re-check fails, the merchant gets notified so they can adjust tax treatment before the next order ships.

This is the feature that turns a Shopify store from a “pay now” retail site into a real wholesale channel. B2B buyers expect to order on account and pay later. Net 30 is standard. Some industries run Net 60.
The mechanics: set a default payment term (e.g., Net 30), assign a default credit limit per company, auto-send invoices when orders are approved, auto-complete orders when payment arrives, and alert your team when new credit orders come in. Credit limits should reflect total outstanding exposure, not just the latest order.

Your finance team or invoicing software needs data that Shopify orders don’t carry by default. Company name. VAT number. PO reference. Payment terms. Tax treatment.
Order enrichment adds this automatically. You define a note template with placeholders ({{company_name}}, {{vat_number}}, {{po_number}}) and tag each B2B order (e.g., “b2b-order”, “net-30”). The result: every order arrives at your finance team invoice-ready, without a single manual edit.
Some merchants don’t want retail visitors seeing wholesale prices. Catalog mode hides price elements on product pages, collections, and the homepage for non-logged-in visitors. The products are visible, but pricing only appears after a customer logs in with an approved B2B account.
This works through a theme app block. Enable catalog mode in your settings, add the block in Theme Editor, and guest visitors see your products without prices. Approved customers see everything.
Instead of manually creating discount codes for each approved company, let the system generate unique codes automatically. You control the percentage, usage limits, whether codes are one-use-per-customer, and minimum order thresholds.
Each approved company gets their own code. No sharing, no leakage, no manual work. When a new company gets approved, their code is created and communicated automatically.
Price lists, product catalogs, commercial terms, seasonal brochures. B2B customers need these documents to place orders, and sending them as email attachments is a recipe for version chaos.
A document portal tied to B2B accounts gives customers self-service access to current files. When you upload a new price list, the old one disappears. When a customer is approved, they see documents. When they’re not, they don’t. No manual sharing, no outdated files floating around.

Companies change addresses, update contact details, modify their tax information. Two governance options work here: auto-approve changes (fast, hands-off) or require merchant review (controlled, suitable for regulated industries or when address changes affect tax treatment).
Either way, the customer initiates the update from their account. No support tickets, no email back-and-forth.
Every B2B event generates communication needs. A customer gets approved: they need to know. A credit order comes in: the merchant needs to review it. An address changes: finance needs a heads-up.
Customizable email templates let you control the exact message for approvals, rejections, new registration alerts, and credit order notifications. For merchants using automation tools, event triggers can connect to Shopify Flow or other workflow platforms.
If you sell across EU markets, your B2B communications need to speak the customer’s language. Not just “we translated the storefront.” The approval email, the invoice reminder, the success message after placing a net terms order, the form labels on your registration page. All of it.
A localized B2B portal detects active storefront languages and provides per-locale templates for every customer-facing message. Your Dutch buyer sees Dutch. Your Italian buyer sees Italian. Your internal team still sees everything in their preferred language.
Work through these in order. Each step builds on the previous one.
The strongest Shopify B2B stores don’t rely on manual heroics. They use clear rules for approvals, tax compliance, credit control, and order data so the whole team can scale without adding headcount or risk. Every feature on this list exists to replace a manual process with an automated one, and to replace tribal knowledge with system rules.
