Develop leaders around Onlineshop: What does it cost?

Use CMS- & E-commerce platforms, cost calculator: onlineshop, solution: commerce & e-commerce and Comparison: Shopware vs. Magento as structured next steps.

“What does an online shop cost?” is one of the most frequently asked questions in the IT project business – and at the same time one of the most difficult to answer.

The honest answer: between €3,000 and €150,000, depending on needs.

This article shows which cost drivers are really relevant, which system types fit for which companies and how to make a sound decision as a midsize company.

Cost drivers at the online shop

1. System type: Standard vs. Individual

Standard Shop Systems (Shopware, WooCommerce, Magento Open Source):

• License: 0–500 €/month
• Facility: 3,000–30,000 €
• Adjustments: 1.000–50.000 €
• Current costs: Hosting + Updates + Plugins.

Custom shop solution (own development):

• Development: 40.000–150.000 €
• No license fees
• Full control of functions and scaling.
• Maintenance by the development partner.

2. Functional scope

function	effort
Product catalog, shopping cart, checkout	Base – included
Custom price logic (shore prices, discount groups)	medium (2–5 days)
ERP/PIM connection	high (5–20 days)
B2B portal with customer account	high (10-30 days)
Internationalization / Multilingualism	medium–high
Configurator logic / CPQ	very high

3. Data volume and integration complexity

A shop with 200 articles and manual care is technically trivial.

A shop with 50,000 variants, automatic ERP comparison, own stock and cross-channel price maintenance is a full project.

The more your online shop needs to be integrated with existing systems (ERP, CRM, commodities management), the higher the project costs – and the greater the added value compared to an island solution.

What the hourly price really means

Short: Agencies typically pay €80–150/h.

Agencies typically pay €80–150/h. Cheaper offers (< 50 €/h) often come from low-wage countries – this is not flat-rate.

However, the communication costs, quality risks and lack of legal certainty (GDPR, contract law) should be calculated.

Groenewold IT Solutions works exclusively with German developers at the site Leer (Ostfriesland). All projects run at an agreed fixed price – without hidden hourly bills.

Current costs after launch

An online shop is not a unique project – it needs regular care:

Cost block	Monthly (estimate)
Hosting (managed)	50–500 €
Plugin licenses / platform license	0–800 €
Security updates, patches	2–8 h/month
SEO / Content-Pflege	custom
Support / further development	as required

Decision aid: Standard or Individual solution?

Standard shop system recommended if:

• Your product catalog < 5,000 items with little variance.
• No complex ERP integration required.
• Budget < 50,000 €
• Fast go-live more important than maximum adaptability.

Custom solution recommended if:

• Complex B2B logic (customer prices, approval workflows, configurators).
• Deep integration into existing enterprise systems.
• separate scaling needs
• Long-term independence of platform providers desired.

FAQ: Onlineshop Costs

Short: How long does the development of an online shop take?

How long does the development of an online shop take? Standard shops with small size: 6–12 weeks. Custom solutions with ERP integration: 4–9 months.

What shop system is the best? Shopware 6 is most widely used and well recorded in German mid-sized firms.

For maximum individuality, a development based on modern frameworks (Next.js, NestJS, Laravel) is recommended.

What does the connection to our ERP cost? Depending on the ERP system and integration depth between 5,000 € (CSV-based) and 80,000 € (real-time API integration).

We clarify the exact costs in the first interview.

Do we smoke a PIM system for our online shop? PIM (Product Information Management) is recommended from about 1,000 products or in complex variants.

It saves long-term care and prevents inconsistencies.

Can Groenewold IT Solutions expand my existing shop? Yes. We also take over the further development of existing shopware or WooCommerce installations.

Typical stumbling stones – and how to bypass them

Short: Scope-Creep arises when needs are re-suspended without new prioritization.

Scope-Creep arises when needs are re-suspended without new prioritization. Antidote: clear product-over roll, visible backlog and recorded “later” list.

Selective test data lead to surprises in production. Invest early in anonymized snapshots or generated records covering edge cases.

Knowledge islands between development and operation cause long incident times.

Common runbooks, common demos and a common glossary on technical terms reduce friction – especially in complex topics such as Onlineshop. What does it cost? .

Checklist (compact, customizable)

• Monitoring on business figures, not just infrastructure.
• Set up cost and license monitoring for cloud/environment.
• Plan documentation and short courses for key users.
• Set goals, KPI and non-scope in writing.
• Record performance budgets and accessibility in QA.
• Track dependencies on third-party providers and API versioning.

Measurability and quality assurance

Define Erfolg on measurable criteria – for example reduced processing time, lower escalations or higher conversion – and not only managed via “Go-live”.

For onlineshop, a slim set of automated tests is worth on the most important user journeys plus targeted manual exploratory tests before releases.

Quality is also created by code reviews, architecture decision logs (ADR) and clear handovers to the operation. Runbooks, escalation paths and recorded border cases.

Knowledge remains in the company – regardless of custom persons or service providers.
