Outsourced Bookkeeping Cost: What to Expect in 2024

"Outsourced bookkeeping" gets thrown around as if it were one thing. It isn't. The phrase covers everything from a $10/hour offshore team doing data entry to a $90/hour onshore firm that delivers reviewed, audit-ready books. The spread between those is 9x, and most businesses end up somewhere in the middle without knowing what they're actually paying for.

Here's what outsourced bookkeeping really costs in 2024, broken down by model, geography, and what's included. The numbers come from BLS OES 2024 wage data across the 390+ US metros we track, plus prevailing market rates for offshore providers. You can run your own numbers in the calculator or browse the full city directory once you know which model fits.

What "outsourced bookkeeping" actually means

Outsourced bookkeeping just means your books are handled by someone outside your company — not a W-2 employee. That umbrella covers three very different arrangements:

The cost differences between these three aren't marginal. They're structural. Understanding them is the whole game.

The cost models

Outsourced bookkeepers price in three ways. The model matters as much as the rate, because it changes your total bill and their incentives.

ModelTypical rangeBest for
Hourly$27–$90/hr (onshore)Messy or unpredictable engagements, cleanups
Monthly retainer$800–$3,500/moSteady, recurring work — most small businesses
Per-transaction / flat fee$1–$5/txn or $300–$1,500/mo flatHigh-volume, simple transactions (e-commerce)

For most businesses, a monthly retainer is the sweet spot: predictable cost, predictable service, and the bookkeeper isn't incentivized to stretch hours. Hourly makes sense when your volume is genuinely erratic. Flat per-transaction pricing works for e-commerce with thousands of identical sales — but read the fine print on what counts as a "transaction," because scope disputes are common.

Onshore vs offshore: the real comparison

This is the decision that drives most of your cost. Here's a side-by-side using current market rates.

FactorOnshore (US-based)Offshore
Hourly rate$50–$90/hr$10–$30/hr
Monthly retainer (40 hrs)$1,200–$3,000$400–$1,000
Median effective rate~$55/hr~$18/hr
Time zone overlapFullLimited (often nights/weekends)
QuickBooks / Xero fluencyNative, certified commonVariable; usually QBO-trained
US tax & sales tax knowledgeStrongOften limited
CommunicationDirect, native EnglishMostly async, possible language friction
Data security oversightUS law applies (state privacy laws)Weaker legal recourse

The 3–5x cost difference is real, and so is the quality gap. Offshore works best when your books are simple, your transaction types are repetitive, and you're comfortable reviewing work asynchronously. Onshore wins when you need someone who understands US payroll taxes, multi-state sales tax, or who can sit in on a call with your CPA without you translating.

A common hybrid: an offshore team handles routine data entry and categorization at low cost, while a US-based bookkeeper (or you) reviews monthly. You get the savings without the accuracy risk. The catch is you have to actually do the review — a hybrid only works if someone competent is signing off.

What's typically included

A standard outsourced monthly retainer should cover:

Things that usually cost extra: payroll processing, sales tax filings, 1099 prep, inventory tracking, multi-entity or multi-currency consolidation, catch-up work, year-end tax packages for your CPA, and any advisory or forecasting work. If a quote looks surprisingly low, it's almost always because these aren't included — clarify scope before signing.

The hidden costs

How to choose

Match the model to your actual needs, not to the cheapest headline rate:

  1. Simple books, tight budget: Offshore team with a monthly US review. Expect $600–$1,200/month all-in.
  2. Growing business, moderate complexity: Solo onshore freelancer on retainer. $1,200–$2,500/month.
  3. Multi-entity, payroll, inventory, or audit prep: Onshore firm with review layer. $2,500–$5,000+/month.
  4. One-time cleanup only: Hourly with a US bookkeeper. $500–$2,500, scoped tightly.

Across our 390+ metros, the typical 40-hour onshore retainer lands near $2,200/month. Use that as a sanity check.

Red flags

The bottom line

Outsourced bookkeeping spans roughly $400/month for basic offshore work up to $5,000+/month for a reviewed, multi-entity onshore engagement. The headline rate is the smallest part of the decision — what's included, where the bookkeeper sits, and how scope is bounded determine your real cost. Get a written engagement letter, confirm what's in and out of scope, and benchmark any quote against your local market using the cost calculator or the city directory before you sign.
