How Much Does Bookkeeping Cost in Boston in 2026?
Bookkeeping in Boston costs anywhere from $200 to $3,500 per month for most small and mid-sized businesses. At A&I Financials, we publish our rates openly: $499.99/month for under 100 transactions (Silver), $999.99/month for 100–200 transactions (Gold), and $1,999.99/month for 200+ transactions (Platinum).
Bookkeeping pricing isn’t always easy to find online — many Boston firms prefer to share rates after a consultation, which is one of the reasons we decided to publish ours upfront. The rest of this post breaks down what actually drives these prices, what you should expect to pay no matter which firm you choose, and the hidden costs to watch out for.
The quick answer — what bookkeeping costs in Boston by business type
Here’s what real Boston businesses are paying for bookkeeping in 2026, alongside A&I Financials’ published rates for the same scope:
| Your business looks like… | Boston market range | A&I Financials price |
| Solo consultant or one-person LLC (under 50 transactions/month) | $200 – $550 | Silver — $499.99 |
| Small business with 50–100 transactions | $400 – $700 | Silver — $499.99 |
| Growing business with payroll and 100–200 transactions | $800 – $1,400 | Gold — $999.99 |
| Established business with 200+ transactions | $1,500 – $3,500 | Platinum — $1,999.99 |
| Startup needing investor-grade reporting | $1,500 – $5,000+ | Custom quote |
If you’re getting Boston quotes dramatically outside this range, it’s worth asking why. Sometimes the firm is bundling services you don’t need; sometimes it’s missing services you do.
What A&I Financials charges (and why we publish our pricing)
A&I Financials offers three published tiers for bookkeeping in Boston. Here’s what each one covers:
Silver tier — $499.99/month
For businesses with under 100 transactions per month. This is most freelancers, consultants, solo LLCs, and small service businesses just getting started.
What’s included: – Income and expense tracking – Accounts receivable management – Accounts payable management – Monthly categorization in QuickBooks Online or Xero.
Gold tier — $999.99/month
For businesses with 100 to 200 transactions per month. This is most established small businesses with regular customer activity and a few credit cards or bank accounts.
What’s included (everything in Silver plus): – Daily bank reconciliation – Multi-account reconciliation (banks + credit cards) – Cleaner month-end close
Platinum tier — $1,999.99/month
For businesses with 200+ transactions per month. This is typically growth-stage companies, multi-location operations, or businesses with payroll and inventory complexity.
What’s included (everything in Gold plus): – Cash-basis financial statements (P&L, balance sheet, cash flow) – Tax support documentation – Year-end close ready for your CPA.
Custom packages
For businesses outside these tiers — unusual industry requirements, multiple entities, international operations, or investor-grade monthly reporting — we build a custom package after a free 30-minute consultation.
Why we publish our pricing
We believe transparent pricing helps both sides of the conversation. You can budget accurately and compare apples-to-apples without filling out a contact form first. And when we do speak, the first call can focus on whether we’re a genuine fit for your business — not on negotiating a starting number.
Transparent pricing also means you can comparison-shop honestly. If you find a Boston firm offering similar scope for less, take it. If you find a firm offering more for the same money, we’d genuinely like to hear about it — we benchmark our pricing twice a year and adjust when the market shifts.
Why bookkeeping prices vary so widely
Five factors drive almost all the variation in pricing. Understanding them helps you compare quotes fairly — whether you’re looking at A&I or anyone else in Boston.
Transaction volume is the biggest factor
A “transaction” is any line item that has to be categorized — a customer payment received, a bill paid, a credit card charge, a bank fee. Most Boston firms (including A&I) price in tiers based on volume: under 100/month, 100 200/month, 200+/month. The price roughly doubles between each tier because the work roughly doubles.
Quick check: pull your bank and credit card statements for the last three months and count the lines. That’s your real transaction count. Most owners underestimate by about half.
What’s actually included
“Bookkeeping” means different things to different firms. At minimum, every bookkeeper should categorize transactions and reconcile your bank accounts each month. Beyond that, scope varies enormously:
Basic: transaction categorization + monthly bank reconciliation
Standard: the above + accounts payable + accounts receivable + monthly financial statements
Full-service: the above + payroll integration + sales tax filings + 1099 prep + cleanup of older books
Controller-level: the above + month-end close + management reports + KPI dashboards + audit prep
A $400/month quote and a $1,400/month quote can both be fair — for very different scopes. Always get a written list of what’s included.
The software you use (or pay for)
Most bookkeepers in Boston use QuickBooks Online or Xero. If you don’t have a subscription, you’ll pay roughly $30 to $150 per month for the software itself — separately from the bookkeeper’s fee.
At A&I, the QuickBooks Online subscription is your responsibility (passed through at Intuit’s published rate). Some Boston firms bundle the software into their fee. Both models are reasonable; ask which one applies before signing.
Your industry’s complexity
A consulting firm with one bank account and 30 invoices a month is simple. A construction company with job costing, three credit cards, lien waivers, and percentage-of-completion accounting is not. Same with restaurants (tip allocation, daily deposits), e-commerce (multi-channel reconciliation, sales tax across states), and healthcare practices (insurance receivables, HIPAA-aware document handling).
If you’re in a complex industry, expect to pay 25–50% more than the basic ranges above. The work itself takes longer.
Cleanup and catch-up
If your books are behind, you’ll typically pay extra to bring them current before monthly service starts. Cleanup fees in Boston typically run $500 to $2,500 as a one-time charge, depending on how many months are behind and how messy things are. Worth doing — going forward with a clean baseline saves money long-term.
Hourly vs flat monthly: which is better for your business?
Two pricing models are common in the Boston market.
Hourly rates run roughly: – Independent freelance bookkeepers: $35 – $75/hour – Boston-based accounting firms with junior bookkeepers: $60 – $120/hour – CPA firms doing bookkeeping: $100 – $250/hour
Flat monthly fees are increasingly common — and for most ongoing engagements, they tend to be the better deal. A&I uses the flat monthly model exclusively because we think it aligns our incentives with yours. Here’s the side-by-side:
| Hourly | Flat monthly (what A&I mostly uses) | |
| Predictable cost | No — varies every month | Yes — same fee, same scope |
| Bookkeeper is incentivized to… | Spend more time | Be efficient |
| Easy to budget | No | Yes |
| Good for one-off projects (cleanup) | Yes | No |
| Good for ongoing monthly work | No | Yes |
The honest answer: hourly is right for cleanup or one-time projects; flat monthly is right for ongoing work. If you have steady monthly transaction volume, you’ll usually save money and stress on a flat-fee plan — regardless of which firm you choose.
Hidden costs to watch for
A few items don’t always make it into a headline quote, so it’s worth asking specifically about each one before you sign with anyone:
Software subscriptions — usually $30–150/month for QuickBooks or Xero, sometimes passed through, sometimes included
Year-end cleanup — some firms charge a separate fee to close out the books for your CPA at year-end. At A&I, year-end close is included in the Platinum tier; on Gold and Silver, we add it only when needed and bill at
our standard rate.
1099 prep — typically $5–25 per 1099 issued
Sales tax filings — usually extra if you operate in multiple states
Catch-up fees — for any months not covered in your starting engagement
Document collection time — some firms bill extra when they have to chase you for receipts or statements
Software conversion — if you’re moving from one platform to another (e.g., QuickBooks Desktop to QuickBooks Online), expect $300–1,000
A good firm will tell you about these proactively. If you have to ask, ask — and get the answers in writing.
How to estimate your bookkeeping cost in 4 questions
Quick worksheet for any Boston business:
1. How many transactions did you have last month? – Under 50 → $300–$450/month market range, A&I Silver at $499.99 – 50–100 → $450–$700/month market range, A&I Silver at $499.99 – 100–200 → $700-$1,200/month market range, A&I Gold at $999.99 – 200+ → $1,200–$2,500/month market range, A&I Platinum at $1,999.99
2. Do you process payroll? – If yes, add about $50–150/month depending on employee count – (Payroll software like Gusto is separate, usually $40–80/month)
3. Do you have inventory, multi-state sales, or anything complex? – If yes, add 25–50% to the market estimate – A&I adds a complexity factor only on a custom basis after a quick review
Are your books currently up to date? – If no, expect a one-time cleanup fee of $500–$2,500 across most Boston firms
That ballpark will land within about 20% of what most Boston firms will quote.
Frequently asked questions
At A&I Financials, bookkeeping costs $499.99 per month for the Silver tier (under 100 transactions), $999.99 per month for the Gold tier (100–200 transactions), and $1,999.99 per month for the Platinum tier (200+ transactions).
Across the broader Boston market, prices range from $200 to $3,500 per month depending on transaction volume and what’s included. The main factor in pricing is transaction count, followed by service scope. A&I Financials publishes pricing online; some Boston firms prefer to share rates during a consultation.
No, bookkeeping and tax preparation are separate services. A bookkeeper keeps your financial records organized throughout the year. A tax preparer (typically a CPA or Enrolled Agent) uses those records to file your annual returns.
Many firms — including A&I Financials — offer both, but they’re priced separately. A common bundle: $999/month bookkeeping + $1,500–$3,000 annual tax filing for a typical small business.
A bookkeeper records and categorizes transactions, reconciles accounts, and produces basic financial statements.
An accountant does the same, plus interpretation, adjusting entries, and higher-level reporting — and usually holds a bachelor’s degree in accounting.
A CPA (Certified Public Accountant) is a licensed accountant who can also sign off on audits, reviews, and certain tax filings. You don’t need a CPA to keep your books, but you’ll likely want CPA involvement for tax planning, audits, or formal financial reporting.
Yes, if you have under 30 transactions a month and the time. QuickBooks Online’s Self-Employed plan ($20/month) plus a bank feed can keep most one-person businesses organized. The math shifts once you’re over 50 transactions or your time is worth more than $40/hour — at that point, outsourcing usually pays for itself in saved hours and avoided mistakes at tax time.
Once a month, minimum. The longer transactions sit uncategorized, the harder they are to remember and the higher the chance of errors. Most professional bookkeepers update weekly or daily via bank feeds, then close out the month within 10 business days of month-end. At A&I we close by the 7th business day of the following month
for Gold and Platinum tiers.
Catch-up work is common. A bookkeeper will typically quote a flat one-time cleanup fee based on how many months are behind and how complete your records are. Once you’re current, you transition to standard monthly service.
For a typical Boston small business, expect $500–$2,500 for cleanup of a year of books. Worth doing — you can’t file taxes, get a loan, or sell the business without clean books anyway. A&I quotes cleanup fees after a free 30-minute review of your existing records.
Not strictly. Most bookkeeping in 2026 is virtual — cloud-based software, bank feeds, video calls. That said, a Boston-area firm understands Massachusetts state tax rules, Boston-specific compliance (like the local meals tax), and local business culture in a way that a national virtual provider may not.
For most owner-operated businesses, a hybrid model — virtual day-to-day, with the option of in-person meetings — works best. A&I Financials is based in Cambridge and offers both fully-virtual delivery and in-person meetings throughout the greater Boston area.
