Why This Matters

Messy books cost more than time

Messy books cost more than time

Bad bookkeeping doesn't just create a headache, it creates real, expensive consequences. A few ways this shows up.

Bad bookkeeping doesn't just create a headache, it creates real, expensive consequences. A few ways this shows up.

Working overtime

Nights and Weekends on QuickBooks

You're already working all day, then logging into QuickBooks at night and on weekends just to keep up.

A bookkeeper gives you back those hours every month.

Tax season scramble

The Year-End Mad Dash

Every January (or worse, every April), you're scrambling to pull everything together for your CPA.

With a bookkeeper, everything's already in order, just hand it off.

Lost in the numbers

Invoices Out, Answers Unclear

You're sending invoices, but tracking revenue, undeposited funds, and expenses has become its own job.

A bookkeeper reconciles and balances all of it, every month.

Falling behind

When Life (or Growth) Gets in the Way

Business is booming, or life just got busy, and somewhere along the way, the books fell behind.

Catch-up gets you current, and monthly upkeep keeps you there.

Profitability questions

Which Job Actually Made Money?

With multiple projects running, it's hard to tell which ones are actually profitable.

A bookkeeper tracks revenue and expenses by job site or project, so you know exactly where you stand.

If that's you, ZL Bookkeeping handles it.

Accurate, consistent bookkeeping in a format your CPA will love during tax season.

No long-term contracts. No surprises. Just clean, current books every month, managed personally by someone who's kept the books for large companies.

Services

What I do

Everything here is aimed at one outcome: books that are accurate enough that your CPA can focus on filing and planning, not cleanup.

Ongoing support

Maintained every month

01

Monthly Bookkeeping

Ongoing transaction categorization, account upkeep, and a clean general ledger, maintained every month so nothing piles up.

03

Profit & Expense Tracking

A clear, ongoing view of what's coming in and what's going out, including accurate customer, vendor, and invoice tracking. Every month, not just year-end.

04

Financial Reporting

Monthly P&L, balance sheet, and other reports that give you a real read on your business, and give your CPA exactly what they need.

05

Payroll Reconciliation

I reconcile your general ledger to your payroll each month. I'll post your payroll reports into your books accurately, so your numbers stay clean.

Setup & Integration

Keep your tools synced

06

QuickBooks Online Integration

I'll set up your QB connections and automate syncs so data flows accurately between your tools. Ongoing monitoring keeps everything running smoothly.

One-time cleanup

For getting current first

07

Cleanup & Catch-Up

Behind on your books, or inherited a mess from a previous bookkeeper? I'll get your file reconciled, corrected, and current, then move you into regular monthly service.

All services are built primarily around QuickBooks Online. If you're on a different platform, reach out and we can talk about whether it's a fit.

Where to Start

Not sure which service you need?

Most businesses fall into one of three starting points. Here's how to tell which one is you.

If Your Books Are A Mess

Start with Cleanup & Catch-Up

Missing months, reconciliations that don't tie, or a file you inherited from someone else. This gets you back to a clean baseline.

My Background

A decade of getting it right

Zach, senior bookkeeper and founder of ZL Bookkeeping, portrait photo

Hi, I'm Zach. I've spent 10 years in senior accounting roles across healthcare, tech, startups, and large corporations, ranging from $1M to several hundred million in revenue. In healthcare specifically, I've worked with complex insurance reimbursement, claims, and deferred revenue. You'll work directly with me. Not a rotating team, just one person who knows your books.

When I'm not managing books, I'm a full-time firefighter and paramedic. Same principles apply: show up, pay attention, don't cut corners. I'm based in New Hampshire with my family and two dogs, spending free time hiking and being outside.

Let's take the stress out of your books so you can focus on what you do best.

"I took over the treasury position for our non profit organization. We had lost our tax status and needed to catch up on three years of bookkeeping. Zach made this project easy for me to achieve. He was well versed with quickbooks and made himself available to answer any questions I had. I was able to take the work he put in to reclaim our tax status with no issues."
