The Accounting Outsourcing Checklist

How to use this checklist

This page is built to be worked, not read. Copy it into your tracker, assign an owner to each line, and date anything with a filing deadline.

The phases run in order. Skipping ahead is the most common cause of a bad transition, because a provider cannot fix a scope you never defined. Delete what does not apply, deliberately rather than by omission.

Before you start

Readiness work is cheap and transition work is expensive. The goal is a scope a provider can price without guessing, plus an honest picture of your books. Expect one to three weeks.

Define the scope

0 of 5 done

Write down which functions you are outsourcing (bookkeeping, full accounting, controller, fractional CFO) and note inventory, multicurrency, job costing, audit or investor reporting needs.
List what explicitly stays in-house, including approvals and payment release.
Count legal entities and intercompany activity, and record monthly transaction volumes, AP and AR counts, headcount and payroll frequency.
Decide cash or accrual basis, and say so in the scope document.
Identify revenue recognition complexity: subscriptions, milestones, grants, deferred revenue.

Document the current state

0 of 4 done

Export a current trial balance, note any account you cannot explain, and identify the last fully reconciled month.
List every system in the finance stack, its owner, and who holds admin rights.
Confirm your QuickBooks Online plan and renewal date, since list prices change on renewals from August 1, 2026.⁶
Write down how many calendar days your close takes, measured to distribution.

Pin the compliance calendar

0 of 3 done

Confirm monthly or semiweekly depositor status against the $50,000 lookback threshold, and note the $100,000 next-day deposit rule.¹
Diary Form 941 quarterly filing dates, and January 31 for Form 940, W-2s to employees and the SSA, and Form 1099-NEC.²⁷
Count your information returns; 10 or more aggregated returns must be e-filed, and list state and local filings.⁷

During selection

Comparisons only work when everyone quotes the same scope. Send the same document to every provider and insist on one deliverable list. Allow two to four weeks.

0 of 9 done

Shortlist three to five providers, send an identical scope document to each, and ask for recurring and one-time fees separately.
Benchmark onboarding and cleanup quotes against published examples: Bench lists $1,200 onboarding, Bookkeeper360 lists prior-period cleanup from $1,000, and Kruze notes a one-time onboarding fee applies.⁴⁵⁹
Ask for the named accounting lead, their backup, and who signs off on the close.
Ask for a committed close timeline in calendar days, and what a retainer actually includes.
Confirm whether payroll tax filings and 1099 and W-2 preparation are in scope.
Ask who bears the cost of a missed deposit, given failure-to-deposit penalties of 2%, 5%, 10% and 15% depending on lateness.⁸
Confirm you retain ownership of the accounting data file, and ask about security, access controls and background checks.
Read the termination clause, notice period, and data handover terms.
Check the contract for scope-change pricing, so growth does not become a renegotiation.

Onboarding

Onboarding is where scope becomes reality: access, documentation, cleanup, and a dated cutover. Budget four to eight weeks and protect it. A rushed cutover produces a bad first close.

Access and setup

0 of 3 done

Grant accounting system access at defined permission levels, not admin by default, and set up read-only bank and card feeds.
Grant payroll system access, and confirm who can approve a run.
Confirm EFTPS access, that federal deposits stay on electronic funds transfer, and that IRS and state authorizations exist.²

Documentation and cleanup

0 of 5 done

Deliver the chart of accounts and agree any restructuring before cutover.
Hand over the last reconciled trial balance as the opening position.
Complete prior-period cleanup and get written confirmation of the periods now clean.
Document AP approval thresholds and the revenue recognition policy in writing.
Agree the monthly reporting pack contents and format.

Cutover

0 of 3 done

Set a cutover date at a period boundary, never mid-month.
Run one parallel close if a filing deadline falls within eight weeks of cutover.
Confirm in writing who is responsible for the next 941 and the next deposit.¹²

First 90 days

The first three closes tell you whether the engagement works. Measure them rather than judging by feel, and raise issues in the first cycle, not the third.

0 of 7 done

Track close cycle time in calendar days for each of the first three months.
Compare against the APQC benchmark: median 6.4 days, top quartile 4.8 days or less, bottom quartile 10 or more, across 2,300 organizations.³
Confirm all balance sheet accounts are reconciled, not just cash, and review the first reporting pack line by line.
Verify the first payroll tax deposit and the first 941 landed on schedule.¹²
Test the AP approval workflow with a live payment, and confirm whoever records payments does not release them.
Log every error and its root cause, and review them at 30 and 90 days with the named lead.
Confirm the contract scope matches the work actually being done.

What good looks like at day 90
Area	Good	Needs attention
Close cycle time	At or below the 6.4-day median³	10 or more days, APQC’s bottom quartile³
Reconciliations	All balance sheet accounts reconciled monthly	Cash only
Payroll compliance	Deposits and 941 on schedule, no notices¹²⁸	Any failure-to-deposit notice⁸
Reporting	Same pack, same day, every month	Format changes each cycle
Access control	Least privilege, documented	Shared logins, ex-staff access
Escalation	Named lead responds in agreed times	Requests go to a general inbox

Ongoing

After 90 days the relationship shifts from transition to governance. The work is lighter but not zero, and the annual review is where scope drift gets corrected.

0 of 5 done

Hold a monthly close review with the named lead and a quarterly business review on metrics, issues and upcoming changes.
Re-check depositor status each year, since the lookback threshold can move you between monthly and semiweekly.¹
Review the January 31 calendar every fall, before it is urgent.²⁷
Review pricing against scope annually before the renewal date.
Maintain a documented exit plan and test it with a full data export once a year.

Questions

Questions people ask about this

How long should the transition take?

One to three weeks of readiness, two to four of selection, four to eight of onboarding. Compressing onboarding is what most often produces a poor first close.

Do I need cleanup before I switch?

If your last fully reconciled month is more than a quarter old, yes. Price it separately. Bookkeeper360 publishes prior-period cleanup from $1,000.⁵

What close timeline should I ask for?

APQC's benchmark across 2,300 organizations puts the median at 6.4 calendar days and the top quartile at 4.8 days or less.³ Ask for a committed number in the contract.

Who is liable if a payroll deposit is missed?

Your business remains responsible to the IRS. Failure-to-deposit penalties run 2% for 1 to 5 days late, 5% for 6 to 15 days, 10% beyond 15 days, and 15% after an IRS notice.⁸ Agree in writing who absorbs a penalty caused by provider error.

Do I have to e-file my 1099s?

If you file 10 or more aggregated information returns, yes, for returns due on or after January 1, 2024.⁷ Confirm your provider files electronically.

What does Finalert charge?

Finalert quotes after a scoping call. Bring transaction volumes, entity count, headcount, and your current close timeline so the quote reflects real scope.
