About David

I help companies selling on Amazon to automate their operations and integrate their business processes with Microsoft Dynamics 365 Business Central, reducing administrative time, errors, and operational costs.

For over 17 years, I have worked in financial management, operations, and international e-commerce within a business group dedicated to the distribution of games and toys, leading digital transformation and process automation projects.

My specialty is connecting business with technology. I don't just know Amazon or Business Central independently; I design and implement processes that integrate sales, taxation, logistics, administration, and ERP to function as a single system.

I don't develop software; I design processes that enable technical teams to develop solutions aligned with real needs.

I can help you with:

• Integration of Amazon Seller and Vendor with Microsoft Dynamics 365 Business Central.

• Automation of administrative and operational processes.

• European taxation for e-commerce (VAT, OSS, and EPR).

• Design and optimization of reconciliation and invoicing processes.

• Development of dashboards with Power BI.

• Functional analysis and coordination with development teams.

One of the most relevant projects I have led has been the functional design of a tax and commercial validation system to automate the management of over 120,000 annual Amazon Seller orders, incorporating automatic validations and significantly reducing the time spent on manual checks.

My way of working always starts from the business. First, I understand the process, identify areas for improvement, and from there, I define the most efficient solution together with the technical teams.

If you are looking for a consultant who understands both daily operations and the technology needed to automate them, I will be happy to help you.

Understand the business before the software.
