Guidelines for Selling a Custom Microsoft Access Application

Understand the legal considerations and distribution methods when preparing a custom Access database for commercial sale.

As a developer, applications you build entirely from scratch in Microsoft Access are generally considered your intellectual property. This means you have the right to sell and distribute your original work. However, you must carefully manage how users access the database and avoid reselling proprietary Microsoft assets.

Build from scratch

Ensure your database is entirely your own work. Do not incorporate, modify, or resell Microsoft-provided templates or proprietary sample code, as these are protected by Microsoft's licensing terms.

Utilize Microsoft Access Runtime

To allow customers to use your database without purchasing a full Microsoft Access license, direct them to download the free Microsoft Access Runtime. Alternatively, bundle the Runtime installer if permitted by the current Microsoft EULA.

Compile and protect your code

Before distributing your product, save your database as an .ACCDE file. This process compiles your VBA code and locks the design of your forms and reports, protecting your intellectual property from end-user modification.

Draft a proper EULA

Work with a legal professional to draft an End User License Agreement (EULA) specific to your database. This document will define the terms of use, limit your liability, and establish your copyright ownership.
