Convert your Access database
to a modern web application.
That Microsoft Access database has run your operation for years — and now it's slow, crashing with multiple users, brushing the 2GB limit, and understood by exactly one person. We convert Access databases into modern web applications: same workflows your team knows, none of the structural problems, full source code ownership.
Migrated by senior engineers with a reconciled, parallel-run process — your data and your business rules arrive intact, verified against the numbers you already trust.
Why Access databases hit a wall
Access is a great prototyping tool that quietly became your production system. These are the failure modes that bring businesses to us:
The 2GB wall
Access databases hard-stop at 2GB. As you approach it, corruption risk climbs and performance falls off a cliff — usually right when the business depends on it most.
"Someone else is in the file"
Access was never built for real multi-user work. Locking conflicts, mysterious crashes, and one user's session corrupting everyone's day are structural, not fixable.
Key-person risk
The person who built it retired, left, or is the only one who dares open the VBA editor. Every day it runs unmaintained is accumulating business risk.
No remote access
Your team works from job sites, home, and the road — but the database lives on one office PC or a fragile shared drive that VPNs merely tolerate.
It can't talk to anything
QuickBooks, your CRM, scheduling, e-signature — modern tools integrate over APIs. Access sits alone, fed by re-typing.
Compliance & backup gaps
A single .accdb file on a shared drive has no audit trail, no role-based permissions, and a backup story that's usually "hope."
Our 7-step migration process
The whole process is built around one rule: nothing gets retired until the new system has proven itself on your real work.
Free assessment
A call plus a look at your database (under NDA if you like). You get an honest read: modernize now, stabilize first, or leave it alone.
Data & logic audit
We map every table, query, form, and VBA routine — including the undocumented rules the business actually runs on.
Fixed-price proposal
A written scope with a fixed budget and timeline. You know the full cost before we write a line of code.
Database migration
Your data moves to PostgreSQL or SQL Server — cleaned, validated, and reconciled against the old system's numbers.
Web application build
A modern browser-based app rebuilds your forms and reports — familiar workflows, minus the crashes, plus the features Access never allowed.
Parallel run & training
Old and new run side-by-side on real work until the numbers match and your team is confident. Nothing is cut over on faith.
Launch & support
We retire the Access file, hand you documentation and full source code ownership, and stay available for changes and support.
What replaces Access
A custom web application on a real database — PostgreSQL or SQL Server — running in your own cloud account. It works in any browser on any device, handles as many simultaneous users as you can hire, backs itself up automatically, and connects to the rest of your tools over APIs: QuickBooks, CRMs, scheduling, payments.
And it's yours: full source code ownership, documentation, and no per-seat license fees — with Skilak available as a long-term partner for changes, or any competent developer able to pick it up from our docs. The same applies to Excel/VBA systems we're asked to replace — the approach is identical.
Frequently asked questions
How much does it cost to convert an Access database to a web application?
Most Access-to-web conversions land between $15,000 and $60,000, depending on how many forms, reports, and VBA routines the database contains. After a free assessment and a short audit, you get a fixed written quote — not an hourly estimate that grows.
How long does an Access migration take?
A typical single-department Access database converts in 6–14 weeks, including the parallel-run period. Larger multi-user systems with heavy VBA take longer. You keep using Access throughout — there's no downtime window.
Will we lose our data or reports in the migration?
No. Data migration is reconciled line-by-line against your existing numbers, and every report you actually use is rebuilt in the new system before cutover. The parallel-run phase exists precisely so nothing is retired until the new system has proven itself.
Can you handle the VBA code and macros?
Yes. VBA is where the real business rules hide, and reading it is a core part of our audit. The logic is carried into the new application in modern, maintainable code — and documented in plain English, often for the first time.
What replaces Access — do we have to buy new software?
You get a custom web application running on your own cloud account (or server), backed by PostgreSQL or SQL Server. It works in any browser on any device, needs no per-seat database licenses, and you own the source code outright.
