The verdict in three sentences
A single ecommerce site serving both consumers and trade customers in Munich sits in a 2026 market ballpark of €25,000 to €100,000, ex VAT, with €350 to €1,600 a month in running costs. Two items drive most of the spread: the trade portal with customer-specific pricing and ERP sync, which alone can vary by a factor of two. Ask for a quote in days per item, with the exact data flows of the ERP sync written down, before you compare totals.
The itemised quote, line by line
Take a Munich specialty coffee roaster with 250 SKUs (beans, equipment, accessories) that sells online to consumers, including subscriptions, and supplies 140 cafés and offices across Bavaria by phone and email. It wants one store in German and English. The quote assumes €800 a day, a 2026 estimate for a Munich agency.
| Item | Scope | Days of work | Cost (EUR, ex VAT) |
|---|---|---|---|
| Discovery | Workshops on both journeys, pricing rules, user roles | 4 to 6 | 3,200 to 4,800 |
| UX and UI design | Consumer and trade journeys, mobile first | 8 to 12 | 6,400 to 9,600 |
| Platform build and catalogue | 250 SKUs, grind and size variants, subscriptions | 8 to 12 | 6,400 to 9,600 |
| Trade portal | Price lists per café, volume tiers, quick reorder, pay on invoice | 10 to 16 | 8,000 to 12,800 |
| English version | Bilingual setup, URL handling, translation import | 3 to 5 | 2,400 to 4,000 |
| ERP sync | Stock, prices, orders, invoices, customer accounts | 10 to 20 | 8,000 to 16,000 |
| Payments, shipping, legal checkout | Payment methods, carriers, Impressum, compliant order button | 3 to 5 | 2,400 to 4,000 |
| Testing, SEO migration, training | QA, redirects from the old shop, handover | 4 to 6 | 3,200 to 4,800 |
| Total | 50 to 82 | 40,000 to 65,600 |
German ecommerce law sets specific checkout requirements, including a clearly labelled order button and full seller information. Have your counsel or a trusted legal text provider review the checkout rather than relying on the agency alone. Quotes near €100,000 usually add a B2B quote module for large accounts, marketplace connectors or a custom subscription engine.
Which platform for combined B2C and B2B
| Option | Indicative build (EUR) | Recurring cost | Strength | Watch out for |
|---|---|---|---|---|
| Shopify with B2B features | 25,000 to 55,000 | Monthly subscription, public price varies by plan | Managed hosting and security | B2B features limited to certain plans |
| Shopware | 30,000 to 70,000 | Hosting, edition-dependent licence | Strong in German-speaking markets | Specialist agencies needed for complex B2B |
| WooCommerce with B2B extensions | 25,000 to 50,000 | Hosting and extension licences | Flexible, low entry cost | Many extensions to maintain |
| B2B-focused open source platform | 50,000 to 100,000 | Hosting, specialist maintenance | Complex pricing out of the box | Scarce skills, higher cost |
| Custom build | 60,000 to 100,000 and up | Dedicated maintenance | Fits your exact rules | Vendor dependency |

Mini case study
Illustrative example, not a real client: Lukas, managing director of a Munich coffee roaster, turns over €1.6 million, 45% from cafés and offices. His team rekeys trade orders received by email for about 2.5 hours a day. He approves a quote of €55,000 plus €800 a month, or €64,600 in year one.

The trade portal removes most of the rekeying: about 550 hours a year at a loaded €38 an hour, or €20,900 a year. If online reordering lifts trade revenue by 6%, that is €43,200 at a 40% margin, adding €17,280 of margin. The project pays back in under two years, before counting consumer growth or fewer order errors.
FAQ
What does a combined B2C and B2B store cost in Munich in 2026?
The ballpark is €25,000 to €100,000. For 250 SKUs, two languages and ERP sync, most serious quotes fall between €40,000 and €66,000.
Do we need separate sites for consumers and trade?
Rarely. One store with a gated trade area usually costs 20% to 30% less than two sites, and the catalogue is maintained once.
What does ERP sync cost?
€8,000 to €16,000 in this quote, for 10 to 20 days of work. Price depends on whether your ERP has an API and how many data flows you sync.
How long does it take?
Allow 4 to 6 months, including 3 to 4 weeks of testing. Avoid launching in the run-up to Christmas, when roasters see their peak.
Is an English version worth it?
For international consumers and expat-run cafés, often yes. Here it takes 3 to 5 days of setup plus external translation costs.
