Full-Service Business Central Solution Center. 🙌
We provide you with everything you need to operate Business Central successfully: With support, new implementation, migration, programming customization, upgrade, external accounting and licensing, we cover all your needs with our consultants and developers. Free online group training courses round off our offer.
After the introduction of Business Central, we were faced with a number of challenges. Changes to the standard behavior of Business Central were necessary, which could only be solved by individual programming. We opted for IOI because, in addition to short response times, the price and performance had to be right. The performance of IO Integrated is still convincing!

Sascha Marquardt and Thomas Marquardt from IO Integrated have proven to be extremely competent and committed partners. Their expertise, professional approach and commitment have exceeded our expectations. We are extremely satisfied with their work and appreciate the sustainable improvement they have achieved for our company.

I can recommend Mr. Marquardt from IO Integrated without reservation. His work - for over a decade - has always been convincing.

As part of the main contract, our implementation partner IO Integrated implemented automated billing of agency fees in the period from May 2021 to December 2021 on the basis of Microsoft Business Solutions SaaS. Subsequent system enhancements were completed by January 2023. We would like to take this opportunity to thank Sascha Marquardt in particular for his consistently friendly, competent and solution-oriented cooperation. We look forward to continuing our good cooperation for future tasks.

Tech Debt Analysis: Uncovering the hidden costs and risks of tech debt.
Individual adaptations often lead to confusing complexity and high follow-up costs – a classic example of technical debt (tech debt). This arises from unstructured developments that become difficult to maintain over time.
Especially in M&A transactions, it is crucial to clearly understand the risks and costs of the existing system. We provide a comprehensive analysis of your NAV/Navision system, identify tech debt and assess potential impacts. This gives you full transparency and a sound basis for your next step.

External Accounting: Outsourcing Business Central accounting.
Our external accounting service takes the burden of bookkeeping off your shoulders and ensures structured financial processes. We prepare Business Central for your bookkeeping, post current business transactions and offer many other accounting services. This leaves you free to concentrate on your core business and benefit from clean, clear bookkeeping in line with Business Central standards.
