What an MS Access VBA Automation Expert Actually Does

Every business running on Access seems to have one: the export somebody runs by hand every Friday afternoon, the report that takes forty minutes of copying and pasting, the supplier file that gets checked line by line before anyone dares import it. I've spent more than ten years doing this work, and most of what an MS Access VBA automation expert actually does is find those routines and replace them with code that runs in seconds and never mistypes anything.

VBA, Visual Basic for Applications, is the programming language built into Access. It's the difference between a database that stores records and one that does work on its own. "Automation" stays a vague word until you see the specific jobs it does, so let me walk through them, along with what a real project involves and how to spot someone who claims this skill but doesn't have it.

The Tasks Businesses Actually Pay to Automate

Across 1,500-plus clients, the requests cluster into four categories. If your team does any of these by hand, a few days of VBA work can often remove the job entirely.

Reports that build and send themselves

The most common request by a wide margin. Instead of someone running queries, pasting results into Excel, tidying the formatting, exporting a PDF, and attaching it to an email, one procedure does all of it. Date ranges fill themselves in, each manager receives only their own region's figures, and the email goes out through Outlook at 7 a.m. whether anyone is at a desk or not.

Imports that check their own work

Businesses receive files constantly. Supplier price lists, bank exports, timesheets from some legacy system that will never be replaced. VBA can watch a folder, open whatever arrives, validate every row against rules you define, import the clean records, and write the rejects to a log with a reason attached. The validation matters more than the import: a bad row caught at the door never gets the chance to quietly corrupt a report three months later.

Keeping two systems in step

Plenty of companies run Access alongside something else. An accounting package, a SQL Server database, an Excel workbook a director refuses to give up. Code that synchronizes records between them on a schedule ends the double data entry, and with it the mismatches nobody notices until an audit does.

Documents from live data

Quotes, invoices, contract letters, appointment reminders. VBA fills a Word template or builds a PDF straight from the record, so the letter always matches the data, and generating fifty takes about as long as generating one.

One category is deliberately missing from this list: things a saved query or a simple macro already handles. Writing code for those is billing you for the wrong tool. Knowing when not to write VBA is part of the expertise.

What a Real Automation Engagement Involves

There's no mystery to the process. A typical project with me runs in five steps:

1. I watch the job being done by hand, and I ask the person who actually does it, not just their manager. The Friday export always has an undocumented step seven that only one member of staff knows about.
2. We agree the scope in writing: which tasks, which files, and what should happen when something fails.
3. I build against a copy of your database. The live file stays untouched until the code has proven itself.
4. We test with your ugliest real data, not a tidy sample. The supplier file with an extra column and a date typed as text is exactly what the code has to survive.
5. I hand over with error handling, logging, and documentation included.

That last step is where cheap automation and professional automation part ways. Code that works on a sunny day is easy. The real work is deciding what happens when the folder is empty, the file has a column missing, or Outlook throws a security prompt. Every routine I deliver logs what it did and fails loudly with a readable message instead of dying on a numbered runtime error.

Cost-wise, this is smaller than most people expect. Many automation jobs are one to three days of work, and my rate for work on an existing database is $30/hour, so a typical small project lands in the low hundreds of dollars. Set that against an employee spending five hours every week on the same task and the payback period is measured in weeks. The details of what this covers are on my VBA programming and macros service page.

How to Spot a "VBA Expert" Who Isn't One

Access has a low barrier to entry, which is mostly a good thing, but it means plenty of people who once recorded an Excel macro now advertise automation services. A few tells show up again and again in code I get called in to rescue:

• No error handling anywhere. The moment anything unexpected happens, the user gets a raw "Run-time error 3021" and a frozen form.
• One giant procedure doing everything. Five hundred lines behind a single button, impossible to test or modify safely.
• Code doing a query's job, looping through records one at a time to change a value that a single UPDATE query would handle in a fraction of a second.
• A firm quote before they've seen your workflow. Nobody can price automation without watching the process it replaces.
• Delivering only a compiled .accde file and keeping the source, which makes them the only person on earth who can ever change your system.

Two questions filter most of this out before you hire. Ask to see a sample of their code; even if you can't read VBA, you can see whether comments exist and whether the code is broken into named, sensible pieces. Then ask how they handle errors. Anyone doing this work seriously will have an immediate, specific answer.

Frequently Asked Questions

Can automation be added to an existing Access database without breaking it?

Yes, and that's most of my work. VBA sits alongside your existing tables, forms, and queries rather than replacing them. I build and test against a copy first, so the live database only changes once the new code has proven itself. Some of the databases I've automated were originally built fifteen years ago.

How much does MS Access VBA automation cost?

My rate for work on an existing database is $30/hour, and small automation jobs usually take one to three days. Larger projects involving several systems take longer and get a fixed quote up front. Describe the manual task you want rid of and I can usually give a rough estimate in one conversation — contact me for a free quote.

What happens when an Office update breaks the code?

It's rarer than the horror stories suggest, but it happens, usually around library references or Outlook security changes. Well-written code with explicit references and proper error handling survives most updates untouched. When something does break, the fix is normally a short job, and clients on an ongoing support arrangement have it handled without opening a new project.

Will another developer be able to maintain the automation later?

If it was written properly, yes. You should receive the full source, commented code, and documentation describing what each routine does; that's my standard handover. Any developer who resists giving you those things is planning to charge you rent on your own database.
