The process

Live in 14 days.
Reviewed every month.

No 90-day onboarding nightmare. No mystery process. Here's exactly what working with us actually looks like.

01

Discovery call

30 minutes. We review your current setup, walk you through the Yesler Portal, and quote a clear monthly engagement scoped to your business — before any work begins.

02

Onboarding

We connect to your bookkeeping software (or set you up fresh in QuickBooks/Xero), build your Portal, and your dedicated Massachusetts-savvy team learns your business. Live in 14 days.

03

Monthly close, 3-tier review

AI handles the first pass. Your dedicated specialist reviews and catches edge cases. Senior management or our in-house CPA signs off. You see every step in the Portal.

Why Boston picks us

Massachusetts-aware bookkeeping.
Real humans on every account.

National firms treat you like a number. Small local shops disappear when their one bookkeeper takes vacation. We're built differently.

Massachusetts-specific expertise

We handle MA corporate excise tax (the $456 minimum + 8% on net income + property/net worth tax), navigate MA PFML compliance (employer and employee portions), file sales and meals tax through MassTaxConnect, and understand the R&D credit qualifications that biotech and tech founders care about.

Three layers of review on everything

AI handles the repetitive work. Your staff specialist checks it and handles edge cases. Senior management or our in-house CPA signs off before anything is finalized. No single point of failure, no "trust us" black box.

Multi-platform specialists

QuickBooks Online & Desktop, Xero, FreshBooks, Wave, Sage. We work where you already do — your books stay where your CPA, lender, and tax software expect them.

Eastern business hours

Your dedicated team is available during EST. Same-day responses on weekday messages. No outsourced call centers, no 3am email chains.

Right-sized for your business — and scales with you

Whether you're a one-person shop, an owner-operator with a small team, or a multi-entity company outgrowing your last firm, we scope every engagement to where you actually are. As you grow, your team stays the same — we scale alongside you instead of handing you off to a different tier.

Free 30-min demo

Built to scale with your business.

Whether you're a solo founder finally getting your books in order or a multi-entity company outgrowing your last firm — we'll show you what life looks like with Yesler running your back office.

We're a Cambridge-based biotech running through a Series A — we needed real bookkeeping that understood R&D credit qualifications and our partnerships with two academic institutions. Yesler cleaned up two years of self-managed books, and now our CFO actually trusts the numbers. Their three-tier review caught things our last firm missed entirely.

FAQ

Questions Boston business owners ask.

Honest answers to what we hear before every demo.

Are you actually based in Boston?
We're a US-based remote team that specializes in serving Massachusetts businesses. Every team member is in the US, and your dedicated bookkeeper is available during Eastern business hours. We've handled bookkeeping for Boston-area companies across biotech, tech, healthcare, real estate, restaurants, and professional services — we know the Massachusetts-specific quirks national firms miss. If meeting in person matters to you, we can also arrange that.
Do you handle Massachusetts corporate excise tax?
Yes — every year, included with your engagement. We file your MA corporate excise (the $456 minimum + 8% on net income + the property/net worth measure), navigate MA PFML compliance for both employer and employee portions, and handle the annual reporting that catches out-of-state firms off-guard. We file everything through MassTaxConnect on schedule.
We're a biotech / life sciences startup — can you handle R&D credits and grant accounting?
Yes. R&D tax credit qualification documentation, federal and Massachusetts R&D credit filings, grant revenue recognition (NIH, SBIR, private foundations), milestone-based revenue accounting, multi-entity rollups for clinical-stage subsidiaries, and the qualified small business stock (QSBS) tracking that matters for founders. We've worked with Kendall Square and Seaport-area biotechs at every stage.
How do MA sales and meals taxes work?
Massachusetts sales tax is a flat 6.25% statewide — there are no local sales tax add-ons, which is unusual. Meals tax is also 6.25%, but cities and towns can opt in to a local 0.75% meals option, taking certain restaurants to 7%. We file everything through MassTaxConnect on the correct schedule (monthly, quarterly, or annual depending on volume). If you ship interstate, multi-state economic nexus is also handled.
We're already in QuickBooks Desktop — is that a problem?
Not at all. A lot of established Boston-area service businesses, real estate operators, and family-owned shops still run QBD because it works. We work in it daily. We'll only recommend migrating to QuickBooks Online if it would genuinely serve you better (multi-user remote access, better integrations, etc.) — and if so, we handle the entire migration. No pressure either way.
I'm a solo founder / small business — am I the right fit?
Yes — small businesses are a big part of who we serve. Whether you're a solo founder finally getting your books in order, an owner-operator running a small shop, or a 1–10 employee business that's outgrown DIY QuickBooks, we're built for you. You get the same dedicated team, the same Portal, the same three-tier monthly close as our largest clients — scoped to where you actually are today. As you grow, we scale with you; we don't push you onto a different tier or hand you off mid-relationship.
How fast can you actually start?
Live in 14 days for most Boston clients from the day you sign on. Onboarding takes about a week (connecting to your software, building your Portal, getting your team up to speed on your business). Catch-up work — if you need 6 or 12 months brought current — runs in parallel and finishes within 30–45 days for most cases. If you need it faster because of a lender, audit, or MA Department of Revenue deadline, tell us during the demo; we can usually accommodate.
