I demystify finances for 7 & 8 figure business owners | Founder @ Celerity Accounting | Top 100 Proadvisor 2024

I’m Tailor Hartman, founder and CEO of Celerity Accounting.

We’re a fractional accounting and advisory firm for 7 and 8-figure businesses using NetSuite and QuickBooks Online.

If your books are messy, your reports are unclear, or you’re scaling fast without the right financial visibility, we’re the team that fixes it.

A few milestones along the way:

- Named one of CPA Practice Advisor’s “40 Under 40 CPAs in the Profession” 
- Built Celerity from a solo operation into a trusted partner for $5–50M businesses.
- Launched a modern firm owner newsletter called "The Net Effect" for accountants

We partner with e-commerce, manufacturing, and other growth-minded companies to turn chaos into clarity.

Because accounting shouldn’t just be about compliance. It should be a system that drives better decisions, faster growth, and fewer surprises.

At Celerity, we don’t just clean up your numbers. We own the outcome. That means clear communication, controller-level oversight, and real partnership.

If your NetSuite or QBO setup isn’t doing its job, let’s fix it.

Happy to connect and share what we’ve learned!

How a Michelin-star potato changed how I think about business.

I went to a Michelin restaurant for my birthday.

It was one of the most memorable food experiences I’ve ever had.

One dish in particular blew my mind.

They serve a hot-and-cold potato.
Hot on the outside.
Cold on the inside.

In 34 years, I’d never really thought about temperature as a variable in food.

But that one detail completely changed the experience.

And it got me thinking, what's the one variable people overlook in accounting firms?

Everyone knows clean books, solid systems, and accurate numbers are important.

But what gets missed?

For me, it's timing.

Month-end reports tell you what happened after the fact. By the time you see the numbers, the decisions are already behind you.

Real-time or near real-time financials change that. When you can make decisions with fresh data, a whole new world of opportunities opens up.

Same data.
Different moment.
Totally different experience.

In accounting, timing is a variable that can completely alter the outcomes.

Bringing clarity, speed & automation to $5–50M SMBs | Founder @ Celerity

I’ve been obsessed with the Japanese concept of umami.

Umami roughly translates to “the essence of deliciousness.”

It’s about balance, subtlety, and drawing out the natural qualities of good ingredients.

Nothing jumps out.
Nothing feels forced.
Everything works together.

That's exactly how I want to come off to my clients.

Not as a firm offering a collection of services.
But as an overall experience.

Most accountants try to create value by adding more. Deliverables. Dashboards. Meetings.

But "more" doesn't always mean "better".

A great service gives clients peace of mind.

It feels like everything is under control.
Like problems surface early.
Like decisions are easier than they used to be.

Clients don’t experience that as individual actions but as a whole.

Nothing flashy.
Nothing missing.

Just a sense that the business finally makes sense.

That’s the standard I care about.

That’s umami.

One of the most common mistakes I see in growing firms:

Confusing capacity with capability.

Just because you have time doesn’t mean you should take the work.

This usually doesn’t show up as a big decision.

It shows up in small moments.

You start with a tight core: Monthly accounting. Clean closes. Clear reporting.

Then something extra sneaks in.
“Can you help with sales tax?”
“Can you take care of payroll too?”
“Can you just fill this out?”

You look at the calendar.
There’s space.
So you say yes.

Nothing breaks right away.

But now there’s:
• Another checklist someone has to remember
• Another exception that doesn’t fit the process
• Another handoff that only one person understands

And slowly,
Month-end takes longer.
Reviews require more context.
Mistakes are harder to catch.

That’s the difference between capacity and capability.

Capacity asks if you can squeeze it in.

Capability asks if this is something you want to be excellent at, every month, for every client.

Strong firms don’t decide based on open hours. They decide based on what they want their work to look like when things are busy.

If the work pulls you away from what you want to be known for, it doesn’t belong in your scope.

Director of Client Accounting Services (CAS) | CPA | Scaling Operations, Pricing Strategy, Process Design & Tech Innovation in Accounting

I'm down in Cerritos Mexico for a friend's wedding (CONGRATS Megan Leesley, CPA & Campy!!) 🥂 

I’m normally a high velocity traveler. But after Japan & Taiwan, I was in need of slower down time. Mexico beach time was perfect for that. ⛱️ 
 
I spent Sunday morning by the pool, catching up on the stacked-up newsletters in my inbox. I’m an aggressive Unsubscriber, so the ones that accumulate are ones I really value. Sharing some of my favorites:
 
💠 Career Hack - Cassie Divine - this fills this gap I didn’t realize I had when thinking about the less tangible elements of professional work and leadership from a FEMALE PERSPECTIVE, and ultimately in a way that is deeply integrated with life. I feel heard and learn new approaches to thinking about self and interpersonal relationships.
 
💠 AEG Performance & Coaching - Todd Greider, ACC - I don’t recall how I came across Todd’s newsletters, but I remember the first one being so timely leading up to my first large speaking engagement. His topics are often about MINDSET. The elements he talks about are so in alignment with the way I think about things, and he elevates those ideas to a level that gives me stronger groundedness and focus on those values.
 
💠 The CAS Cache - 💸 Luke Templin - he always hits on CAS INSIGHTS that are super relevant for building CAS and developing advisory services. He shares personal stories, experiences, and analogies that make things understandable and approachable. He does this is in speaking sessions on CFO/FP&A topics too. 
 
💠 The Net Effect - Tailor Hartman - super clear, practical takes on FIRM RUNNING. He puts words to things I’ve dealt with but never really named, and once he spells it out, it just clicks. He has great takes on firm operations and client interactions. They’re short, too. He sticks to one main point, so it’s easy to keep up with. It’s a quick read but ends up having way more impact than you’d expect for something you can read in just a few minutes.

▲ Day 0.

Today I’m joining Vercel as Head of Growth.

I have a long history with Vercel — I was a huge fan and power user when they (we?) were still called ZEIT. My three-letter username is so old I can’t edit my profile anymore without an error (we’ll fix that).

Hyper was the first terminal that actually felt like it belonged on my Mac, and that mix of aesthetics, polish, and developer-first thinking matters a lot to me.

I’ve been a front-end developer for a long time — since before React was even a thing if you can believe it. When React came out, routing was client-side and shipping anything meaningful meant duct-taping React and Express and a bunch of other tools together. Then Next.js and now.sh showed up and it felt like magic.

When we migrated the Redis site off of WordPress to Sanity, Vercel was the obvious choice. And when we shipped it, it felt like we had stepped into the future — And we got 6x better performance instantly, massive developer productivity gains, and infinite more joy.

My first time seeing v0 by Vercel was at Redis Released London when Rowan showed me something he had prototyped for the product team (product teams love when the CEO does that). Then I built the first version of Clareo Health (more about that in a near-future post) with v0, using NextJS, ShadCN, and the AI SDK. All hosted on Vercel, because of course.

Rickrolling Keith in my interview project was a bucket list item, and I’m stoked to be getting the marketing bois back together. But most of all, I’m really excited to bring Vercel to a whole lot more developers and help more people experience what it’s like when you can just ship things.

I’ll miss my friends at Redis.
