ERP for Small Businesses — Mid-Market under 50 Employees
An ERP for a German small business is not a scaled-down enterprise product; it is its own market with its own vendors and its own success criteria. Companies under 50 employees need a system that they can implement in months rather than years, run with one or two internal IT-capable people rather than a dedicated team, and pay for in monthly subscription rather than capital outlay. The good news is that this market is well-served: a handful of long-established DACH vendors plus a generation of cloud-native challengers cover almost every variant of the small-business model.
This guide covers what to look for, what to avoid and which vendors actually fit the German Mid-Market small-business segment.
What a small-business ERP must cover
The core feature set for a small Mid-Market business is narrow but uncompromising. Financial accounting must be GoBD-compliant out of the box, with SKR03 and SKR04 chart-of-account templates, DATEV export and immutable audit trails — the German tax authority does not negotiate on this point. Order management covers quotes, orders, delivery notes and invoices, with proper credit-note and cancellation handling that satisfies UStG (Umsatzsteuergesetz) requirements. Inventory at the level of bin or shelf, with at least basic stocktake support and serial / batch tracking for the industries that need it. Procurement with supplier orders, goods receipt and three-way invoice match.
Beyond the core, most small businesses need e-invoicing (ZUGFeRD 2.x and, from 2026 onwards, XRechnung receipt-capability for B2B), banking integration via SEPA and HBCI or FinTS, time tracking for service businesses, CRM-light for sales pipeline visibility and e-commerce integration for shop-driven brands. The boundary between ‘core’ and ‘extra’ depends on the business model, but the German regulatory baseline is the same for everyone.
Budgets and total cost of ownership
For a small business under 50 employees, total cost of ownership over five years for a cloud ERP typically lands between EUR 50,000 and EUR 250,000. The split is roughly 40 % subscription licences, 35 % implementation and customisation, 15 % training and change-management and 10 % integration with surrounding tools. On-premises and hosted on-premises options cost more in year one (hardware and implementation are heavier) but converge with cloud over the five-year horizon for companies that minimise re-implementation cycles.
Per-user list pricing for the German small-business ERP market in 2026 ranges from EUR 25 / month for entry-level products (Lexware Office, Sage 50 Cloud) to EUR 80–150 / month for full-suite mid-market products that small businesses also use (myfactory, weclapp, Business Central). Implementation effort scales with the number of modules and the integration count, not directly with headcount — a 30-person company with a complex production process can require more implementation work than a 200-person trading company.
Vendor landscape
Five vendors dominate the German small-business ERP market.
myfactory — Swiss-German cloud ERP with strong financials, trade and light manufacturing. EU hosting, German-language support, well-suited for trading and service companies up to 200 users.
weclapp — German cloud-native ERP with strong CRM integration and e-commerce focus. Particularly strong for digital-native small businesses and project-driven service companies. Owned by 3U Holding, financially stable.
Sage 50 Cloud / Sage 100 — Sage 50 covers the very smallest businesses (under 10 employees, freelancers, micro-enterprises) with strong DATEV integration. Sage 100 is the next tier up, on-premises or hosted, with more depth in manufacturing and trade.
Lexware Inventory Management / Lexware Office — Haufe Group products targeting micro and small businesses with simple inventory and order management needs. Strong for service businesses and small traders.
SelectLine — Magdeburg-based, on-premises and hosted, with broad coverage from financials to production. Strong in industries with German-specific compliance needs (waste management, recycling, food production).
Two additional categories deserve a look. Microsoft Dynamics 365 Business Central is the natural choice when the small business is already Microsoft-centric and expects to grow past 100 employees. Industry specialists — JTL-Wawi for e-commerce, MOCO for agencies, datev SmartLogin variants for tax-advised micro-enterprises — can outperform horizontal vendors for businesses that fit their niche.
Implementation in a small business
The realistic implementation timeline for a small-business ERP is 3–6 months from contract to go-live for a standard configuration, 6–12 months when significant customisation or integration is involved. The phased approach used in mid-market projects scales down: a discovery phase of 2–4 weeks, a configuration phase of 6–12 weeks, a data-migration and testing phase of 4–8 weeks, a cutover of one to two weeks and a hypercare phase of 2–3 months.
The most common small-business implementation mistake is to staff the project as a part-time side-line. ERP implementation requires a dedicated internal project lead with 50–80 % time allocation for the duration; key users from each module need 20–40 % time during their respective phases. Companies that cannot free this time should defer the project rather than try to compress it — the avoidance cost surfaces during go-live and erases any savings.
Selection criteria for small businesses
- GoBD compliance and DATEV export — non-negotiable for any German operation, must be live on day one
- Cloud or hosted, not self-hosted — few small businesses have the IT capacity to run an ERP server stack securely
- EU data residency — either EU-only or Germany-only, with the BSI C5 attestation question answered in writing
- Implementation partner availability — the vendor matters less than the partner's realistic capacity for a small-business project
- Three- to five-year contract term — long enough to amortise implementation, short enough to renegotiate
- Module-level activation — ability to start with core financials and add modules later without re-implementation
- Healthy partner ecosystem — for surrounding tools (shop, banking, payroll, time tracking)
The single most under-asked selection question is the vendor's implementation-partner capacity for small projects. The big vendors' biggest partners are not interested in a EUR 80k project; the smaller partners may be excellent or barely competent. Reference checks specifically against small-business projects from the last 18 months matter more than any feature comparison.

Frequently Asked Questions
Can a 10-person company really run a real ERP?
Yes, and increasingly should. The cloud-native products (weclapp, myfactory, Lexware Office) start at price points that 10-person companies can absorb, and the operational benefit of a single source of truth across orders, stock and invoicing is meaningful even at that size. The alternative — spreadsheets plus accounting software — works at 5 employees, strains at 10 and collapses at 20. Starting earlier rather than later saves an emergency migration during growth.
What is the cheapest credible option for a German small business?
For micro-enterprises (under 5 employees): Lexware Office Plus or Sage 50 Cloud at EUR 25–60 / month covers accounting, invoicing and basic inventory. For 5–20 employees: weclapp starter or myfactory cloud at EUR 80–150 / month / user covers the full ERP scope. Below those price points the market is dominated by purpose-built accounting tools (sevDesk, BuchhaltungsButler, Billomat) that solve invoicing and accounting but not real ERP.
How long until we can switch off the old system?
For a typical 30-person trading company moving from spreadsheets and Lexware to a real cloud ERP: 4–6 months from contract to a stable go-live, plus a 2–3 month period of partial dual-running for the year-end accounting cycle. Switching off the old system entirely usually happens 8–10 months after contract.
Do we need an implementation partner or can we do it ourselves?
For the very smallest accounting-only setups (Lexware Office, sevDesk): self-implementation is realistic. For real ERP projects starting at weclapp or myfactory: a partner is almost always cheaper than DIY when the cost of go-live mistakes and operational disruption is factored in. The exception is companies with an existing internal team member who has implemented the same product before; that experience compresses the timeline dramatically.
