ERP Selection for SMEs 2026 | Decision Guide

Quick Decision Aid – Which ERP Is Right for You?

Most common mistake: Starting too large (SAP for a 10-person team) or staying too small (Billbee at €5M revenue).

Rules of thumb:

• E-commerce with online shop + marketplaces → Xentral (best integrations)
• Pure B2B with field sales → SAP Business One or weclapp
• Complex manufacturing → SAP or industry-specific ERP

Choosing the right ERP system is one of the most important decisions your business will ever make. Once implemented, the system will accompany you for years — and switching is costly, time-consuming, and risky.

Yet this decision is often underestimated, or made for the wrong reasons. Some companies choose based on price, others on brand recognition, and others after an impressive demo. The result is frustration when the system doesn't perform as expected in daily operations.

In this guide, I'll walk you through a structured approach to making the right ERP decision. You'll learn what categories of systems exist, which system suits which type of business, and which typical mistakes to avoid.

Why ERP Selection Is So Difficult

The difficulty with ERP selection is that there is no objectively best system. There is only the system that best fits your specific situation — and that situation differs from company to company.

An online shop processing 10,000 orders per month has different requirements than a wholesaler with 200 B2B customers. A company with complex manufacturing needs different features than a pure trading business. A company operating internationally faces different compliance requirements than one selling only domestically.

To make matters more challenging, vendors naturally present their systems in the best possible light. Demos are perfectly choreographed, reference customers are carefully selected, and weaknesses are skillfully concealed. As a non-expert, it is difficult to distinguish substance from marketing.

Finally, the ERP decision is a decision about the future. You are not choosing for today, but for the next five to ten years. The system must grow with your business without constantly hitting limitations.

The ERP Landscape in 2026

To help you navigate the market, I divide the ERP landscape into four categories. These categories are based on company size and complexity, not on the quality of the systems themselves.

Category 1: Enterprise ERP for Large Corporations

This category includes systems such as SAP S/4HANA, Oracle ERP Cloud, and Microsoft Dynamics 365 Finance. They target large corporations and major mid-market companies with more than €100 million in revenue.

The advantages of these systems lie in their extreme breadth of functionality. They cover literally every conceivable business process — from complex group consolidation and international compliance to industry-specific processes in chemicals, pharmaceuticals, or automotive. They scale seamlessly to enterprise size and have a global partner infrastructure.

The disadvantages are equally clear: these systems typically cost over €100,000 per year, and implementation takes one to three years. You will need an internal IT team dedicated to the system on an ongoing basis. The complexity is overwhelming for smaller companies.

My honest assessment: for most readers of this article, these systems are massively oversized. They make sense if you have 500 or more employees and need to map international corporate structures. For a growing SME, they are the wrong approach.

Category 2: Mid-Market ERP for Established Businesses

This category includes Microsoft Dynamics 365 Business Central (formerly NAV), SAP Business One, and Sage X3. The target audience is established mid-market companies with revenues between €10 million and €100 million.

These systems offer extensive features for finance, logistics, production, and sales. There is a well-established partner ecosystem with deep industry experience, and specialised vertical solutions exist for many industries.

The cost picture is more nuanced than often portrayed: cloud licences start at around €50 to €110 per user per month — for ten users that is €6,000 to €13,000 per year. On-premise models require higher upfront investments. Implementation typically costs €10,000 to €100,000 and takes six to eighteen months. Individual customisations are possible but expensive. You do not need a full IT team, but you do need at least one key user who engages intensively with the system.

These systems are a good choice for manufacturing companies with complex production processes, for businesses with extensive B2B structures and sales organisations, or for industries where proven vertical solutions exist on these platforms.

Category 3: Cloud ERP for Modern SMEs

This is where Xentral, weclapp, Haufe X360, and similar vendors sit. The target audience is small and medium-sized companies with revenues of €1 million to €30 million, typically in e-commerce or trade-adjacent services.

The major advantage of this category: affordable costs between €4,000 and €10,000 per year. Xentral offers package pricing with unlimited users (from €349 per month); weclapp charges per user (€39 to €169 per user per month). Implementation takes two to eight weeks, and modern interfaces plus continuous updates come without any effort on your part.

The limitations are that these systems are less customisable than the large enterprise solutions. There are fewer vertical solutions, and you are more dependent on the vendor since you do not have your own installation.

For e-commerce businesses that want to grow quickly without spending a fortune on IT, this category is the sweet spot. The systems are modern, implementation is manageable, and costs scale with the business.

Category 4: Entry-Level Solutions for Startups

This category includes Billbee, Easybill, sevDesk, and Lexoffice. They target startups and micro-businesses with revenues below €1 million.

The obvious advantage: these solutions are affordable. Accounting software such as sevDesk (from €155 per year) or Lexoffice (from €71 per year) covers the basics. Billbee for multichannel sellers is usage-based — from €9 base fee plus approximately €0.08 to €0.24 per order, meaning at 500 orders per month you pay around €120. They are ready to use immediately, with virtually no setup effort. For getting started with digital business management, they are ideal.

The limitations become apparent when you grow. Automation options are limited, scalability is constrained, and eventually a system change becomes unavoidable.

My assessment: perfect for getting started, but plan from the outset that you will switch at some point. This is not a flaw in the system — it is simply built for a different audience.

Making the Right Choice: A Structured Process

Instead of deciding intuitively or on gut feeling, I recommend a structured multi-step process.

Step 1: Systematically Document Your Requirements

Before you even start comparing systems, you should document your own requirements. This sounds obvious but is often skipped — with the consequence that you later discover the chosen system cannot handle important things.

Start with your business model: do you sell to end consumers, to business customers, or both? Does your business run primarily online, offline, or as a hybrid? Are you a pure trader, or do you also have your own production?

Then look at volume: how many orders do you process per day or per month? How many items or SKUs do you have in the system? How many employees will work with the system?

Sales channels matter: which shop systems do you use — Shopify, WooCommerce, Magento? Which marketplaces do you sell on — Amazon, eBay, Otto? Which payment providers are connected?

Then the processes: how complex is your warehouse — a single room with shelves, or a real logistics centre? Do you need production or manufacturing planning? How important is automation to your daily operations?

And finally, accounting: do you need DATEV export? What tax scenarios apply — OSS for EU sales, exports to third countries? Does someone handle accounting in-house, or does the tax adviser do it?

Step 2: Calculate Your Budget Realistically

One of the most common mistakes in ERP selection is being overly optimistic about the budget. Licence costs are only one component of the total cost.

For entry-level solutions such as sevDesk or Lexoffice, licences cost €70 to €400 per year. Billbee is usage-based and costs €100 to €5,000 per year depending on order volume. Add zero to €500 for setup, similar amounts for training, virtually no room for customisation, and support is included.

For cloud ERP for SMEs such as Xentral or weclapp, licence costs are €4,000 to €10,000 per year — for weclapp depending on the number of users. Implementation typically costs €2,000 to €10,000, training €1,000 to €3,000, customisation another €2,000 to €10,000, and for ongoing support you should budget €1,000 to €5,000 per year.

Mid-market ERP such as SAP Business One or Business Central costs around €10,000 to €15,000 per year for ten users in the cloud; on-premise licences plus maintenance are higher. Implementation costs €10,000 to €100,000 depending on complexity, training €5,000 to €20,000, customisation €5,000 to €50,000, and support runs €3,000 to €15,000 per year.

As a rule of thumb: budget two to three times the pure licence cost in year one. This covers implementation, training, initial customisations, and unforeseen efforts.

Step 3: Think About the Future

You are not choosing an ERP system for today, but for the next five to ten years. That means thinking about where your business will be during that time.

Are you planning to double or triple revenue? Then scalability matters — not just in terms of cost, but also system performance and processes.

Do you want to expand internationally? Then you will need multi-currency support, potentially multiple languages, and the ability to meet compliance requirements in different countries.

Are you planning new sales channels? Then the system should support flexible integrations — not just the ones relevant today.

Will your team grow? Then pay attention to user models. Some systems charge per user; with others, users are included in the package price. That can make a significant cost difference at ten or twenty users.

Xentral Compared with Alternatives

Since this blog specialises in Xentral, here is an honest comparison with the most relevant alternatives.

Xentral vs. SAP Business One

Both systems target the mid-market, but with different focuses. SAP Business One is strong in production and manufacturing; Xentral is strong in e-commerce.

Costs differ depending on the model: Xentral sits at approximately €4,200 to €8,600 per year (€349–719 per month). SAP Business One now also offers cloud licences from €91 per user per month (Professional) — for ten users that is around €10,900 per year. On-premise licences cost approximately €2,700 per user as a one-time fee plus annual maintenance. In addition, SAP typically involves €10,000 to €50,000 in implementation costs. Implementation takes two to eight weeks with Xentral, six to twelve months with SAP Business One.

In terms of e-commerce functionality, Xentral has clear advantages with native Shopify and Amazon integrations. SAP Business One requires third-party solutions for this. Conversely, SAP Business One leads when it comes to complex manufacturing control, bill of materials, and production planning.

My verdict: for e-commerce companies, Xentral is the better choice. For manufacturing businesses with complex production processes, SAP Business One may make more sense.

Xentral vs. Microsoft Dynamics Business Central

Business Central (formerly NAV) has a broad functional range covering many industries. Xentral is more focused on e-commerce and trading.

The cost structure: Xentral sits at approximately €4,200 to €8,600 per year with unlimited users. Business Central charges per user — new pricing has applied since November 2025: Essentials costs US$80 per user per month, Premium US$110. For ten users on the Essentials plan, that is approximately US$9,600 (around €8,800) per year. Business Central also typically involves €35,000 to €90,000 in implementation costs.

For e-commerce integrations, Xentral has a clear advantage with its Shopify Connector — available directly as an app in the Shopify App Store. Business Central requires third-party solutions that add cost and need to be maintained. Xentral is also better positioned for Amazon and other marketplaces.

My verdict: for e-commerce companies, Xentral is faster and more affordable. Business Central makes sense if you have a broader requirements profile that goes beyond pure trading.

Xentral vs. weclapp

weclapp is Xentral's most direct competitor in the cloud ERP segment for SMEs. Both systems target similar audiences but have different pricing models.

The pricing: Xentral uses package pricing — from €349 per month (Starter) to approximately €719 per month (Business), including unlimited users. weclapp charges per user: €39 per user on the Starter plan, €69 to €89 per user for ERP Services, and €139 to €169 per user for ERP Trade. With a team of five users on the Trade plan, you pay €695 to €845 per month with weclapp.

The biggest difference lies in automation. Xentral Flows enable complex workflow automations — though individual Flow creation is currently only available for Premium customers or through certified partners. weclapp offers simpler but directly accessible automation features.

My verdict: Xentral is particularly worthwhile for larger teams (five or more users), since the number of users is included in the package. weclapp can be cheaper for small teams of two to three users.

Avoiding Typical Mistakes in ERP Selection

From my consulting practice, I know the mistakes that are made time and again. Here are the most common ones and how to avoid them.

Mistake 1: Starting Too Large

The scenario: a company with ten employees and €3 million in revenue opts for SAP because "it's the safe choice."

The problem: implementation takes a year, consumes €150,000, and in the end the company uses perhaps ten percent of the features. The complexity overwhelms the team, nobody wants to use the system, and the hoped-for efficiency gains never materialise.

Better: start with a cloud ERP that fits your current size. If you really grow to the point where you need SAP, you can always switch then — and by that time you will also have the resources to do so.

Mistake 2: Planning Too Small

The scenario: a company with €2 million in revenue and 100 orders per day stays with Billbee because "it works."

The problem: the system hits its limits. Automation is missing, the DATEV export causes problems, and warehouse management is too basic. The team spends hours on manual work that could be automated.

Better: upgrade in time. The switching costs are lower than the cost of inefficient processes over years.

Mistake 3: Deciding Based on Feature Lists

The scenario: you compare three systems in an Excel spreadsheet with 100 features. System A has 85 ticks, System B has 82, so you choose System A.

The problem: most features on the list you will never use. And the features that are truly important to you carry the same weight as all the others in the list.

Better: define your ten most important requirements and check these specifically. Do not be dazzled by feature lists.

Mistake 4: Overrating the Demo

The scenario: the sales rep delivers a perfect demo. Everything runs smoothly, the interface looks sleek, you are impressed.

The problem: demos are choreographed. They show the system's best side, not the daily reality with its rough edges.

Better: contact reference customers and get honest feedback. Test the system yourself — ideally with your own data.

Mistake 5: Underestimating the Internal Team

The scenario: you buy an ERP system and expect the service provider to do everything. Nobody is assigned internally to manage it.

The problem: no ERP implementation works without an internal champion. The service provider does not know your processes in detail, cannot make decisions on your behalf, and needs a contact person for questions.

Better: plan for at least one person to dedicate fifty percent of their time for two to three months to the implementation. This person becomes the internal expert who learns the system and spreads knowledge throughout the team.

Practical Example: A Real ERP Decision

To illustrate what the selection process can look like in practice, here is an anonymised example from my consulting work.

The starting situation: An online shop for office supplies, €1.8 million in revenue, approximately 150 orders per day. The team consisted of five people, two of them in the warehouse. The existing solution was a combination of Billbee and Excel.

The problems: The manual effort was enormous. Orders had to be entered into Billbee partly by hand. The DATEV export was error-prone. The warehouse was chaotic because there was no real inventory management system.

The selection process: We started by documenting the requirements: primarily B2C with some B2B, two channels (own shop and Amazon), DATEV export essential, automation desired, warehouse management needed.

The longlist included: Xentral, weclapp, JTL, Microsoft Business Central. After demos and conversations with reference customers, Xentral and weclapp remained on the shortlist.

The decision went to Xentral — primarily because of the superior automation capabilities through Flows and the stronger Amazon integration.

The result: Implementation took six weeks. Order processing is now eighty percent automated. The DATEV export works reliably. The warehouse was reorganised with proper storage locations.

The costs: Licence approximately €6,000 in year one, implementation approximately €8,000, training approximately €2,000. Total costs in year one: €16,000.

The ROI: The saved working time corresponds to approximately half a full-time position. With employer costs of €35,000 per year, the investment pays for itself within twelve months.

Frequently Asked Questions (FAQ)

How long does an ERP implementation take?

This depends heavily on the system and the complexity. Cloud ERPs like Xentral are typically implemented in two to eight weeks. Mid-market ERPs like SAP Business One require six to twelve months. Enterprise systems can take one to three years.

Can I keep my existing system running in parallel?

Yes, and this is actually recommended. Running both systems in parallel for one to four weeks reduces risk and allows corrections to be made before the old system is switched off.

What happens to my historical data?

Most important data can be migrated: customers, items, open orders, and order history. How far back to migrate is a cost-benefit question. The last twelve to twenty-four months is often sufficient.

Do I need an external consultant?

Not strictly necessary for cloud ERPs, but advisable. A consultant knows the pitfalls and can accelerate implementation. The cost of consulting usually pays for itself through mistakes avoided and faster productivity gains.

What if I am not satisfied with the system?

Switching is possible, but expensive. That is precisely why careful selection is so important. Most vendors have notice periods of three to twelve months.

How do I find the right implementation partner?

Ask for references from your industry. Check whether the partner is certified. Pay attention to chemistry in personal conversations — you will be working closely together.

My Recommendation

For most e-commerce SMEs with revenues of €500,000 to €10 million, Xentral is an excellent choice. It offers rapid implementation, affordable costs from approximately €4,200 per year with unlimited users, strong e-commerce features, and solid DATEV integration. For the full power of automation through Flows, I recommend the Premium package or working with a certified partner.

That said: every business is different. If you have complex manufacturing processes, SAP Business One or Business Central may be a better fit. If you have a small team of two to three users, weclapp is a price-competitive alternative. If you are just getting started, Billbee is sufficient for now.

The right decision can only be found by honestly analysing your own situation and systematically comparing different options. I am happy to help you with that.
