Engagement Models

Three Engagement Models. Pick What Fits Your Needs.

Most common

Per-FTE

A dedicated full-time accountant on your engagement.

  • Learns your workflow, your client portfolio, and your review standards
  • Works as a consistent member of your extended team
  • Best when you have steady monthly volume across multiple clients

Per-Project

A scoped engagement for a defined deliverable.

  • A backlog cleanup, a system migration, or a busy-season tax push
  • Fixed scope and fixed timeline, agreed before we start
  • Best when the work has a clear start and finish

Per-Hour

Variable work that does not fit the first two models.

  • Flexible hours for niche projects or overflow
  • Good for firms testing the partnership before scaling
  • Best when volume is unpredictable month to month
Complimentary trial

From the Founder

Meet Your Partnership Lead

Nimesh Soni

Nimesh Soni

Founder - CPA (US)

I'm a US CPA, and I started Datastub in 2019 after years running accounting and tax seasons - so I know exactly how much of a senior CPA's and partner's time gets lost to work that should never reach a partner's desk.

Over 6+ years in accounting, I've worked across industries - eCommerce, real estate, construction, retail, restaurants, contractors, wholesale, and tech/IT - building teams that handle everything from complex reconciliations and multi-state sales tax to business and international tax filings. My focus has always been the same: books that are accurate, review-ready, and built to fit how a firm already works.

That's the standard I built Datastub on, and it's the one I hold every partnership to.

How We've Helped Firms Like Yours

Three firms, three different problems - here's what partnering with us actually looked like.

Client story

A 15-Person Miami Accounting Firm's Clients Were Waiting on Financials

Outcome

Every set of financials delivered by the 5th

The firm was onboarding new clients, but quality bookkeeping staff were hard to find. They handed over five construction clients, each around $1M in revenue. That first month, we delivered every set of financials by the 5th, clean and ready to pass to clients with no rework. Within three months they moved another 10 clients to us, and today we handle their entire accounting client base.

Client story

CPA Firm in DC: 350 Returns, Four People

Outcome

240 returns prepared during tax season

They were looking at 350+ returns with only three preparers and one reviewer. In February, they brought us in for overflow. We completed 240 returns - prepared, checked, and ready for final sign-off - giving the owner enough room to take on additional extended-deadline clients.

Client story

A CPA Firm in Columbus Was Ready to Leave Its Offshore Team

Outcome

Pilot led to nearly three seasons together

They tested us with one complex tax return involving Forms 5471, FBAR, and FATCA. Our international tax team prepared the return, our in-house CPA reviewed it, and we kept the firm updated daily. The finished return showed the precision and communication they had been missing.

The Workflow

Here's Exactly How We Work Together

01
One-time setup

Access & Setup Review

We connect to your environment, tools, and required access, then review how each client is currently set up - books, chart of accounts, open items, and where things stand.

02
One-time setup

Understanding Your Workflow

We learn how your firm works - your standards, your close process, your review expectations, your month-end deadlines - so we fit into your system.

03
Monthly cycle

Daily Accounting

Day-to-day work begins: recording transactions, reconciliations, and keeping the books current across your client portfolio.

04
Monthly cycle

Month-End Reporting

We close the month and prepare financials and management reports on the deadline you set - clean, accurate, and review-ready.

05
Monthly cycle

Review & Ongoing Support

You review the month-end close, financials, and reports. From there the monthly cycle continues, with daily or weekly check-ins on your schedule.

Frequently Asked Questions

Can we start with just one client, or a pilot?
Yes. Most partnerships start with a one-week pilot — free and no-obligation, on a single client or a defined task — so you can judge our quality, communication, and workflow before committing.
How quickly can you onboard a new partnership?
Within 7 days of signing. The first 24–48 hours covers software access, NDAs, and knowledge-transfer setup. The rest is shadow review or an SOP walkthrough. By the end of week one, your assigned team is producing work for your review.
What services do you offer to CPA firms?
Bookkeeping, accounting and CAS, payroll, month-end and year-end close, and the complete range of tax: individual, business, international, sales and use, and 1099s. Plus audit support and advisory production.
What software are your accountants trained on?
QuickBooks Online and Desktop, Xero, NetSuite, Sage, Drake, ProConnect, Bill.com, Ramp, Gusto, and ADP. If you use something outside this stack, we'll evaluate it before we commit.
How do you communicate day-to-day?
Through your channels — email, Slack, Microsoft Teams, and your project management system. Your assigned accountant keeps in touch daily or weekly, so you get status updates continuously.
Can you handle busy-season volume spikes?
Yes, with scope agreed in advance. Per-FTE engagements scale by adding seats; per-project scaling is common around year-end close and Q1 tax season. The earlier you flag the volume, the cleaner the ramp-up.
How is our client data protected?
In most partnerships we work inside your environment — your RDP or VDI, on the licenses you provide — so your data never leaves your systems. Our team works office-only, with role-based access, no personal devices, and NDAs signed on day one.
What if it's not working, or we want to exit?
No long-term contracts. Exit with 30 days' notice. Simple.
