Frequently Asked Questions

FAQ about Odoo ERP & CRM

Basics & Getting Started

What is Odoo and who is it suitable for?

Odoo is an open source ERP platform with over 50 integrated business apps. Particularly suitable for SMEs that want to map multiple business processes (CRM, sales, warehouse, accounting) in one system without license costs for the core.

Odoo Community vs. Enterprise – which version do we need?

Community is free and covers about 70% of typical requirements. Enterprise offers additional modules (Studio, MRP, marketing automation) and official support. We advise based on your requirements.

Implementation & Migration

How long does an Odoo implementation take?

A standard implementation with CRM and sales takes 4-8 weeks. Complex scenarios with accounting, warehouse, and manufacturing typically take 3-6 months. We start with a pilot to quickly gain experience.

Can you migrate our existing data?

Yes, we have experience with migrations from legacy systems, Excel, or other ERP systems. We analyze data quality first and develop a clean migration strategy with validation.

Customization & Integration

Can Odoo be connected to our existing systems?

Yes, Odoo has a well-documented API. We connect to shop systems (Shopware, WooCommerce), banks (SEPA, Fintech APIs), shipping providers, or your own legacy systems.

Do you develop custom modules?

Yes, when standard modules are not sufficient. We develop industry-specific extensions that map your special processes – upgrade-safe and cleanly separated from the core.

Costs & Support

What does an Odoo project cost?

Strongly depends on scope: A basic implementation starts at around 10,000 €, complex enterprise projects correspondingly higher. Plus optional Enterprise licenses and hosting. Clear offer after consultation.

Do you offer support and maintenance?

Yes, through maintenance contracts with SLAs. We handle updates, monitor the system, and support with user questions. Many customers have been with us for years.

Odoo Implementation: Open-Source ERP for Growing Businesses

Choosing an ERP system is one of the most consequential technology decisions a growing business can make. Odoo stands apart in this landscape as a genuinely modular open-source platform that lets you start with what you need today and expand as your requirements evolve. Unlike monolithic enterprise systems that demand massive upfront investment and months of implementation, Odoo allows a phased approach where you can begin with CRM and sales, then progressively add warehouse management, accounting, and manufacturing modules as your operations grow.

For handing financial data to tax advisors and DATEV-oriented workflows, we also support Odoo–DATEV integration (exports, interfaces, alignment with your accounting firm).

The open-source foundation of Odoo provides advantages that extend well beyond licensing costs. Full access to the source code means we can customize workflows, create industry-specific modules, and build integrations that proprietary platforms would charge premium fees for or simply not support. Our development team writes clean, upgrade-safe customizations that sit alongside the Odoo core, ensuring your specific business logic survives version upgrades without the painful re-implementation cycles that plague heavily customized commercial ERP systems.

Data migration is often the most anxiety-inducing aspect of ERP adoption, and rightfully so. Moving years of customer records, inventory data, and financial history from legacy systems or spreadsheets into Odoo requires meticulous planning and validation. We have migrated data from SAP, Navision, custom Access databases, and countless Excel-based workflows into Odoo environments. Our migration process includes automated data quality checks, reconciliation reports, and parallel-run periods that give your team confidence in the new system before fully committing.

Long-term success with Odoo depends on more than a successful initial implementation. We provide ongoing support contracts that include system monitoring, security updates, user training, and continuous process optimization. As your business evolves, we help configure new modules, adjust workflows, and develop custom reports that keep Odoo aligned with your operational reality. Many of our Odoo clients have been with us for years, growing from small implementations into comprehensive enterprise platforms that manage their entire business lifecycle.
