A Simple IT Checklist for Growing Professional Firms
Growing firms break their technology in a predictable order, so a useful IT checklist follows the same order. The setup that worked fine at five people starts groaning at twelve. The shared drive that made sense for one office turns to soup with two. This checklist for growing professional firms walks through the gaps in the sequence they usually appear, so you can find yours before they find you, typically during the busiest week on your calendar, because that's when strained systems pick their moment.
Work through it honestly. The goal isn't a perfect score. It's knowing exactly where you stand.
Start with the plumbing
Everything else sits on this layer, so start here even though it's dull.
Internet: is it a business-grade connection with bandwidth for your actual peak, and is there a backup connection for the day the primary dies? Firms that live in cloud applications stop working entirely when the internet does.
Network gear: are the router, switches, and access points business-grade and under five years old? Have the default passwords been changed and the firmware updated within living memory? Aging, unconfigured network equipment is the most common source of mystery slowness in small offices.
Workstations: everything under five years old, running a current operating system, patched, with encrypted drives? One ancient machine in the corner running an unsupported OS is a security hole with a keyboard.
This layer is also where growth bites first, because the five-person setup was almost certainly built by accretion. A switch bought in a hurry here, an access point balanced on a filing cabinet there. It all worked fine, right up until headcount doubled.
Printers: working, updated, and on their own network segment. People laugh at printer security right up until they read about how attackers actually move through networks.
The security items that can't wait
If you only fix one section this quarter, fix this one.
Multi-factor authentication on every account that supports it. Email, cloud apps, VPN, practice management. Any account protected by only a password is your most urgent gap, full stop, and it costs nearly nothing to close.
Email defenses beyond the default spam filter: real phishing protection, and encryption available for sensitive sends. Email remains the way attackers reach professional firms, because it works.
Endpoint protection on every device, centrally managed, so someone can actually see alerts across the whole fleet. Ten separate antivirus installs that nobody monitors are ten screens no one is watching.
A business password manager, so shared credentials live somewhere sane instead of a spreadsheet named passwords.xlsx. Which exists at more firms than anyone admits.
And training within the last 12 months, ideally with phishing simulations. Your controls are only as strong as the most tired person clicking email at 11pm, and growing firms have a lot of tired people.
Backups only count if they restore
This is the section where nearly every firm believes it's covered and a surprising number are wrong.
Automated backups of everything critical, because manual backup routines fail the week the person responsible goes on vacation. The 3-2-1 shape: three copies, two kinds of storage, one offsite. A test restore performed in the last 90 days, because an untested backup is an assumption wearing a costume. A known recovery time, compared honestly against how long the firm can survive without its systems. And a written recovery procedure that doesn't live entirely in one person's head, because disasters don't check the vacation calendar.
If the test-restore line made you wince, that's the finding. Do that one this week.
Software sprawl and the licenses nobody uses
Growth breeds tools. Tools breed subscriptions. Eventually nobody knows what the firm pays for.
Build a current inventory of every application and subscription with its annual cost, and expect at least one surprise. Confirm everything runs a supported version, because end-of-life software stops receiving security patches and becomes a standing invitation. Audit the integrations: wherever someone retypes data from one system into another, you're paying an error tax on every entry, and it compounds as you grow.
Then the awkward one: shadow IT. The personal Dropbox, the free AI tool someone pasted client data into, the unofficial spreadsheet that became load-bearing. Ask without blame, because you want the true answer, and the true answer at a growing firm is always longer than the official list. Then make the sanctioned tools good enough that the workarounds stop being tempting, because bans without alternatives just push the sprawl further out of sight.
Who can get into what
Access control decays quietly as headcount grows, which is why it needs a checklist line at all.
Onboarding: a documented setup process, so a new hire is productive on day one instead of watching someone hunt for licenses until Thursday. Offboarding: every account shut off the day someone leaves. Same day. A former employee with live credentials is among the most preventable risks a firm carries, and among the most commonly carried anyway. Periodic access reviews, because people change roles and keep their old keys. And permissions granted by role rather than by individual favor, so the whole thing stays manageable at twice your current size.
The planning layer
The last section separates firms that manage technology from firms that get surprised by it.
An actual annual technology budget covering refresh cycles, subscriptions, and support, because planned spending beats emergency spending every single time. A growing firm is buying equipment on a rolling basis anyway. The budget just decides whether that happens calmly or at retail-plus-panic pricing. A hardware replacement schedule that retires machines before they fail rather than after. A straight answer to the growth question: could your current setup absorb 50 percent more people and clients, and if not, what breaks first? And a simple 12-to-24-month roadmap. A one-page list of planned projects with rough costs is enough. The point is that someone is steering.
If the honest answer is that nobody at the firm has time to be the person steering, that's a role you can rent, and fractional IT management explains what renting it looks like.
Using the list without drowning in it
Don't try to fix everything at once. Nobody does, and the firms that try burn out by section three. Sort your gaps into two piles: risk and friction. Risk items, meaning security gaps, untested backups, and offboarding holes, come first, because those are the ones with a bad week attached. Friction items make the firm faster and can wait their turn.
Timing helps too. Run the list in your slowest month, when there's room to actually fix what you find. An accounting firm auditing its technology in January has located its gaps at the exact moment it can't close them, which is arguably worse than not looking.
Industry wrinkles matter too. Accounting firms carry IRS data-security obligations that shape several of these answers, covered in the piece on IT support for accounting firms. Law firms have confidentiality rules doing the same work, covered in what law firms should expect from IT support.
Run this checklist twice a year and it stops being an audit and starts being a habit, which is the actual goal.

Walking firms through exactly this list is a normal Tuesday here.
