B2B (Wholesale) vs. B2C Online Store — What Are the Differences in Development and Cost

In Brief

B2B (wholesale) and B2C (retail) online stores serve different purposes, so their development requirements differ more than you might initially expect. A B2C store is designed for individual shoppers, with the same product prices for everyone and instant card payments. A B2B store, on the other hand, is built for business customers: each company may have its own price list and discounts, orders often require approval from multiple employees, and payments are frequently made by invoice with 30, 60, or 90-day payment terms. B2B orders also tend to be larger and less frequent than retail purchases. Instead of one-off purchases, businesses typically order regular batches of products under an ongoing agreement. This explains the difference in development costs: a standard online store built by our team costs between €3,000 and €15,000+, while a B2B store with custom pricing, company-specific user roles, and integration with 1C or CRM systems costs more. That's not because the design is more expensive, but because the platform requires more complex business logic. Another common requirement for both models is post-order automation: synchronizing prices between the website and accounting system, automatically sending orders to couriers, and providing electronic delivery confirmation. We've implemented this type of solution in the B2C flower delivery project yesflowers.md, and the same approach can be applied to wholesale operations.

 Key Differences Between B2B and B2C Online Store Development

1. Pricing and Catalog Access

In a B2C store, each product has a single price visible to all website visitors. In B2B, pricing depends on who's viewing it. A long-term wholesale customer might receive one discount, while a new customer gets another. Some parts of the catalog may also be hidden from retail shoppers and accessible only to authorized business partners. For example, a top-tier distributor might receive a 25% discount on a product, while a new wholesale customer gets only 15% on that same item. Technically, this means product prices and catalog visibility aren't managed globally. Instead, they're calculated individually for each authorized account. A standard online store simply doesn't need this level of pricing and access control.

2. Order Placement and Roles Within the Customer's Company

In B2C, one person typically completes an order in a single session, from adding products to the cart to making a payment. In B2B, a single company account often involves several employees with different permissions. For example, a purchasing manager may prepare an order, but only their supervisor or accounting department can approve it or authorize spending beyond a set limit. Another common scenario involves placing one order for multiple locations. A retail chain, for instance, might submit a single purchase order containing different products for different stores, with each location receiving its own shipment. B2B platforms also need features rarely found in retail stores: minimum order quantities or values (MOQ), invoice payments with deferred payment terms instead of immediate card payments, one-click reordering based on purchase history, and bulk order uploads from Excel or CSV files using product SKUs. Net 30 payment terms remain the default for approximately 45% of B2B invoices, while Net 60 and Net 90 terms are also common.

3. Post-Order Automation

This is where B2B and B2C have a lot in common. In both models, it makes sense to automate what happens after an order is placed rather than manually passing information between departments. Orders should move automatically through the process, whether they're going to the warehouse, accounting department, or courier service. The main difference is the scale and complexity of automation. B2B platforms more often require two-way synchronization with 1C or CRM systems, ensuring that inventory levels, prices, and order statuses remain consistent across both systems without manual data entry. In B2C, the priorities are usually faster delivery to the end customer and clear, accessible order tracking. From a technical perspective, both scenarios rely on the same integration architecture, which we'll explore in more detail below.

4. Order Volume, Frequency, and Sales Cycle

A B2C purchase is often spontaneous and can be completed within minutes. A B2B deal, however, may take anywhere from three to twelve months to negotiate, involving six to ten people from the purchasing company, including procurement, finance, IT, and the department that will ultimately use the products. All this can happen even if the final order is placed through the same website. While this doesn't directly change the development process, it explains why certain features are so important in B2B: requests for quotation (RFQ), communication history linked to orders, and access to a dedicated account manager directly from the customer dashboard. Without these tools, managing a lengthy approval and negotiation process becomes significantly more difficult.

Development Costs: B2C vs. B2B

Based on our experience in Moldova, a standard turnkey online store with a product catalog, shopping cart, payment functionality, and customer accounts costs between €3,000 and €15,000+, depending on the number of products and the complexity of integrations. A B2B store starts with the same foundation but requires additional modules that aren't typically needed in retail: customer-specific price lists and discounts, employee roles and internal order approval workflows, deferred payments with credit limit management, and synchronization with 1C or CRM systems. Based on a preliminary estimate, which should always be adjusted to the specific project, these features add approximately €1,500 to €4,000+ to the cost of a basic online store, depending on how many systems need to be connected. Integrating a single external system, such as a payment gateway, 1C, CRM, or courier service, starts at €300 for simpler cases and increases with the complexity of data exchange. A separate consideration is developing a mobile application for couriers or warehouse managers using React Native, our primary technology for mobile development. This is treated as a separate project, with pricing calculated individually based on the number of screens and required integrations.

Automation in Practice: Synchronizing Prices, Orders, and Deliveries

Whether you're running a B2B or B2C store, you'll eventually face the same challenge: once an order has been paid for, it shouldn't get stuck on the website. It needs to reach the warehouse, courier, and accounting system automatically, without anyone having to copy information manually. In practice, this usually involves the following:

• Price synchronization. If your business has different prices for retail and wholesale customers, or regularly updates prices in 1C, your website shouldn't maintain a completely separate set of prices. Otherwise, discrepancies are inevitable. The solution is scheduled or real-time data synchronization between the website and 1C/CRM. When a price changes in the accounting system, it's automatically updated on the website for the appropriate customer group.
• Order synchronization. After payment, the order is automatically created in the accounting system or CRM, without requiring a manager to enter the same information again. This saves time and eliminates errors caused by manual data entry.
• Courier dispatch and delivery confirmation. Orders are also automatically sent to the courier's application or dashboard. There's no need to call or message the courier with instructions, as they can immediately see the order details and delivery address. Once the delivery is completed, the courier records confirmation directly in the app. This might involve issuing an electronic receipt, uploading a photo, or updating the delivery status. The customer's order status is then updated automatically in their account, eliminating the need to call and ask whether the order has arrived.

We implemented this exact type of workflow in the yesflowers.md project, a B2C flower delivery service operating in Chișinău and more than 30 other cities across Moldova. Although it's not a B2B store, the project clearly demonstrates how this automation works: customers place and pay for orders on the website, the orders are automatically assigned to couriers, and couriers use a dedicated mobile app to confirm deliveries and issue electronic receipts on the spot. The project took 3 months to complete and included 3 external integrations. The same principle of synchronizing prices, orders, and statuses between the website, accounting system, and couriers can also be applied to B2B wholesale stores. In wholesale operations, this type of automation reduces the repetitive order-processing work handled by managers, which is typically more complex than in retail.

When Is a Standard Online Store Enough, and When Do You Need a B2B Module?

• A standard B2C store is sufficient if all customers see the same prices, orders are placed by a single person, payments are made immediately by card, and purchases don't require internal approval from the customer's company.
• A B2B module is necessary if certain customers need personalized prices and discounts, orders must be approved by several employees with different permissions, invoice payments with deferred terms are required, or product catalogs and prices need to be hidden from unauthorized visitors.
• Combining both models on one website is a practical and common solution. You can have a public retail storefront with visible prices alongside a restricted B2B section offering personalized price lists to authorized business partners. Technically, this means using a single codebase with different access rules rather than building two separate websites.
• Order and delivery automation makes sense for both business models once manual processing starts slowing down operations. There's no fixed order volume at which automation becomes essential. A better indicator is how much time your managers actually spend manually transferring order information between different systems.

How We Approach These Projects at ilab.md

Our technology stack includes PHP/CodeIgniter and MySQL for web development, along with React Native for mobile applications. This allows us to build both retail and B2B functionality within a single codebase. Access permissions, pricing, and user roles are handled through different rules within the same system, rather than requiring separate websites. If a client only needs a straightforward retail store, we say so and don't push unnecessary approval workflows or role management modules. Adding these features would only introduce complexity where it isn't needed. However, if a business already handles wholesale orders, offers deferred payment terms, or involves multiple employees in purchasing decisions, we plan these features from the beginning. Retrofitting a basic B2C platform with multiple user roles and personalized pricing is always more expensive than designing these capabilities properly from the start. We also handle integrations with 1C, CRM platforms, and courier services as part of the same development process. Based on our experience with yesflowers.md and other integration projects, this automation often saves clients more time and manual work than simply having an online store in the first place.
