The verdict in three sentences
Over 3 years, Shopify Plus totals $160,000 to $205,000 all-in for a B2B manufacturer stacking apps, versus $118,000 to $172,000 for a mid-range custom store. Shopify Plus wins when your catalogue is simple and you also sell to consumers. Custom wins once you manage customer-specific price tiers, negotiated quotes and ordering rules specific to your pharmacy network.
The real cost of Shopify Plus for a B2B manufacturer
The subscription is only the visible part. A cosmetics manufacturer selling to pharmacies needs B2B apps, an ERP connector and an agency for the theme. 2026 orders of magnitude, at $1 = EUR 0.93.
| Shopify Plus item | Monthly cost | 3-year cost |
|---|---|---|
| Plus subscription (3-year term) | $2,300 (EUR 2,140) | EUR 77,000 |
| B2B apps (quotes, tiers, minimum order) | EUR 400 to 900 | EUR 14,000 to 32,000 |
| ERP connector (Celigo, middleware) | EUR 300 to 700 | EUR 11,000 to 25,000 |
| Initial agency setup | Fixed fee | EUR 25,000 to 45,000 |
| Theme maintenance and changes | EUR 500 to 1,000 | EUR 18,000 to 36,000 |
| Payment fees outside Shopify Payments | 0.15 to 0.3% of revenue | Variable |
| Estimated total | EUR 145,000 to 215,000 |
The weak point is not price but dependency: every piece of B2B logic goes through a third-party app, with its own subscription, limits and updates that can break the ordering flow.
The cost of a custom B2B store
Custom requires a heavier upfront investment, but recurring costs are lower and the business logic belongs to you.
| Custom item | 2026 range | Over 3 years |
|---|---|---|
| Initial build (catalogue, accounts, pricing, quotes) | EUR 45,000 to 110,000 | EUR 45,000 to 110,000 |
| Maintenance and changes (15% per year) | EUR 6,750 to 16,500 per year | EUR 20,000 to 50,000 |
| Cloud hosting and CDN | EUR 150 to 400 per month | EUR 5,400 to 14,400 |
| Native ERP connector | Included or EUR 8,000 to 15,000 | EUR 0 to 15,000 |
| Payment fees (Stripe, ACH) | 0.8 to 1.5% on cards | Variable |
| Estimated total | EUR 70,000 to 190,000 |
At mid-range, a EUR 75,000 project costs about EUR 115,000 over 3 years, i.e. EUR 30,000 to 70,000 less than an equivalent app-heavy Shopify Plus setup.
How to decide based on your sales logic
| Criterion | Shopify Plus | Custom |
|---|---|---|
| Mixed B2C and B2B sales | Very well suited | Possible, more expensive |
| Prices per pharmacy and buying group | Via app, limited | Native, unlimited |
| Negotiated quotes and sales approval | Third-party app | Built-in workflow |
| Time to launch | 8 to 12 weeks | 14 to 22 weeks |
| Ownership of code and data | Shopify platform | Full |
| Recurring cost | High and rising with apps | Stable |
The rule of thumb: if more than 30% of your orders go through a quote or a negotiated discount, custom is usually more profitable from year two.

Helen, CEO of a dermatological cosmetics manufacturer in New York, sells to 850 pharmacies with 4 discount levels and quotes for buying groups. Her Shopify Plus estimate: EUR 2,140 subscription, EUR 750 of apps and EUR 500 of connector per month, plus EUR 35,000 setup. Over 3 years: 3,390 x 36 + 35,000 = EUR 157,040 (about $169,000), excluding theme maintenance.
Custom is quoted at EUR 80,000, plus EUR 12,000 maintenance and EUR 3,600 hosting per year. Over 3 years: 80,000 + 46,800 = EUR 126,800 (about $136,000). Savings: EUR 30,240, with a built-in quote workflow and code she owns.
FAQ
Does Shopify Plus handle B2B natively?
Yes, since 2023 Shopify Plus includes B2B features (company catalogues, payment terms). They cover about 70% of simple needs, but multi-step quotes and overlapping discounts still require apps at EUR 100 to 400 per month each.
Is custom riskier?
Risk is managed with precise specifications and delivery in 3 to 4-week increments. Require code ownership and a Git repository in your name from day one.
Can we migrate from Shopify Plus to custom later?
Yes, migrating products, customers and orders takes 3 to 6 weeks. Budget EUR 8,000 to 15,000 for data migration and SEO redirects.
What maintenance budget should we plan for custom?
Plan 12 to 18% of the initial cost per year. For an EUR 80,000 project, that is EUR 10,000 to 14,000 per year.
Which option launches fastest?
Shopify Plus goes live in 8 to 12 weeks, custom in 14 to 22 weeks. A two-phase launch lets you sell from week 10 with a reduced scope.
