Microsoft Dynamics NAV (Navision) and Business Central development services for businesses
I am Evaldas Jablonskas, a Microsoft Dynamics NAV (Navision) and Business Central developer with over 10 years of ERP development experience. I help businesses maintain and extend their existing systems through custom changes, troubleshooting, integrations, reporting and business process automation. I also support older NAV versions using C/AL.
Development services
Support for businesses using Microsoft Dynamics NAV or Business Central, from individual changes to more complex requirements.
Integrations
Data exchange with external systems using SOAP, OData, REST APIs, XML and JSON.
Reports and documents
Development and modification of RDLC and Excel reports, and processing of invoices and other business documents.
Troubleshooting and fixes
Code analysis and diagnosis of issues with imports, VAT calculations and business logic.
Process automation
Optimization of purchasing, sales, financial document and warehouse processes.
Existing system maintenance
Support for older Dynamics NAV (Navision) versions and Business Central On-Premises systems: C/AL and AL code changes, bug fixes and functionality enhancements within an agreed scope.
A solution I developed – BC Invoice Portal
Create Business Central sales invoices through a separate web portal. Staff select a company, customer and items, enter quantities, prices and discounts, while Business Central calculates totals and VAT.
A straightforward way to create and manage unposted sales invoices.
Direct Business Central Cloud integration through standard Microsoft APIs. No custom AL extensions are required; initial Microsoft Entra application setup and Business Central application permissions are necessary.
