How Much Does It Cost to Convert an Access Database to a Web App?

It's the first thing everyone wants to know, and most agencies dodge it. Here's an honest look at what it costs to turn a Microsoft Access database into a web app — and what actually drives the number.

How much does it cost to convert an Access database to a web app?

Most projects land in the low-to-mid five figures. A simple single-purpose tool sits at the lower end; a large, multi-module system with integrations sits at the higher end. The only way to get a real number is from your actual file — which is exactly what our free review gives you, along with an up-front quote. No call required.

What drives the cost?

Four things, mostly:

  • Size and complexity — how many forms, reports, and business rules are in play.
  • Data cleanliness — tidy data converts faster than years of accumulated quirks.
  • Integrations — connections to email, accounting, payments, or other systems.
  • Users and permissions — how many people, and whether you need roles and an audit trail.

Is it worth it?

If your current setup is causing real pain — lockups, corruption, key-person risk, or no remote access — a web app usually pays for itself in saved time and avoided risk. If it's stable and low-risk, maybe it's not time yet — and we'll tell you so.
