Modernizing a decades-old Microsoft Access database and banking application
Tevpro rebuilt a decades-old Access banking application as a web app, tracing financial calculations and period-end controls before replacing its interface and database.
Microsoft Access modernization
Tevpro helps teams map the workflows, rules, data, and integrations inside business-critical Microsoft Access applications. We assess what to stabilize, what to move, and what to rebuild, then plan the work around the people who rely on it.
Why discovery matters
Forms, VBA, macros, queries, reports, and manual handoffs often carry rules that are not documented elsewhere. We inspect the application with the people who use it and identify the processes a replacement must preserve. The result is a scoped decision, not an automatic rewrite.

Choose the right scope
Some teams can keep familiar Access screens while moving the data layer and validating existing workflows. Others need a new web application, updated permissions, and redesigned integrations. We compare the options against risk, maintenance needs, user workflows, and the effort to prove that the new system behaves correctly.

AI-assisted modernization
AI can help organize user walkthroughs into draft workflow tests, surface patterns in queries and code, and prepare candidate mappings or test cases. That can reduce time spent transcribing and structuring discovery, but the output still needs review by engineers and the people who run the application. We validate business rules and expected results before relying on a test or migration plan. Whether this lowers the total project cost depends on the application, the quality of its documentation, and what the review uncovers; we do not price a project by assuming an AI shortcut.

The first engagement
An initial assessment can inventory users, workflows, business rules, data quality, reports, integrations, and operating constraints. From that evidence, we recommend a practical scope, identify the highest-risk unknowns, and define how the critical work will be tested. Delivery estimates follow the assessment, not a table count.

What does it do today, and what needs to change? Share the critical workflows, current pain points, and any timing constraints. We will follow up to discuss a sensible first step.
Common questions
Not always. If the current workflows still serve the business, a staged approach may retain the frontend while the data layer changes. We assess the application before recommending a bridge or full replacement.
