Reports management can explain

The package is structured around revenue, margin, cash, working capital, entities, locations, projects, or other useful dimensions.

One accounting source for tax and decisions

The same reconciled data supports owner meetings, planning projections, lenders, and return preparation.

Quick Answer

Outsourced accounting gives a business an external team for its agreed monthly close, reconciliations, and financial reporting. Taxstra can combine that work with tax preparation and planning. The written scope identifies entities, owner returns, review responsibilities, and any optional CFO support.

Monthly accounting, tax preparation, and planning together

Taxstra can coordinate your monthly accounting, business tax preparation, and proactive tax planning in one engagement. The proposal names the entities, owner returns, reporting needs, and planning work included. Controller oversight and fractional CFO support are separate layers, added where the business needs them.

Each month: close and explain: Reconcile the agreed accounts, review the balance sheet, record payroll and owner activity, and deliver financial statements with unresolved items identified. Agree on whether management needs reporting by location, entity, client, or project. Source-record deadlines and the reporting date belong in the scope.
During the year: connect changes to planning: At the agreed planning cadence, use current books to discuss tax projections and upcoming business changes. New owners, a location opening, equipment purchases, and changes in compensation should reach the planning team before the related decision. Implementation work and additional analysis must be specified.
At year-end: carry the records into preparation: Maintain support for asset activity, loans, payroll, owner balances, and entity transactions throughout the year. Identify the business and owner returns, states, information requests, and review responsibilities covered by the engagement. An owner return is not automatically included with a business return.
Keep the people and services you need: Your bookkeeper or office manager can continue invoicing, gathering records, or processing transactions while Taxstra handles the agreed close and review work. Owners retain payment approvals and operating decisions. Forecasting and CFO meetings are optional; you can combine accounting and tax without buying a CFO engagement.
Scope the transition separately: After engagement, establish the account and entity inventory, access permissions, upcoming deadlines, opening balances, and unresolved items. Price historical cleanup separately from recurring work. Document who owns the first close, who communicates with the former provider, and what changes the ongoing fee.

Need a lighter service? Monthly bookkeeping and tax-preparation-only services remain available. The right scope follows your needs, not a minimum business size.

The problem this solves

The books can be technically complete and operationally useless

The failure usually appears between transaction entry and management use: unreconciled balance-sheet accounts, inconsistent classifications, unexplained changes, missing schedules, and reports delivered without a close owner or decision context.

Bookkeeping stops at the income statement

Cash, debt, receivables, payables, payroll liabilities, owner activity, fixed assets, intercompany balances, and other balance-sheet accounts may not receive consistent reconciliation and review.

The owner becomes the workflow manager

The bookkeeper, payroll provider, bill-pay system, tax preparer, and internal team each need data from someone. Without a defined operating model, the owner spends time routing questions and resolving responsibility gaps.

Reports arrive without explanations

A P&L is not decision support when categories change, unusual items are buried, margins are not segmented, and no one explains variance, cash movement, or the actions management should consider.

How the work moves

A monthly close that moves from source data to management action

The accounting function follows a visible sequence. Each stage has inputs, review responsibilities, open-item rules, and a defined output for the next stage.

01Collect

Control source information

Connect banks, cards, payroll, billing, payables, debt, commerce, and supporting records. Assign responsibility for exceptions and missing documents.

02Close

Reconcile and adjust

Reconcile cash and balance-sheet accounts, record accruals and adjustments, review classifications, and maintain the supporting schedules.

03Review

Apply controller oversight

Challenge unusual balances, trends, cutoff, account mapping, entity activity, owner transactions, and unresolved items before reports are released.

04Report

Explain results and actions

Deliver the financial package with concise commentary, agreed KPIs, cash observations, and a list of decisions or follow-up items.

Scope and deliverables

What the outsourced accounting function should produce

Scope varies with systems, volume, entities, and management needs. The engagement should still define recurring outputs clearly enough that the owner can tell whether the function is operating as designed.

Monthly close package

Reconciled financial statements, comparative results, balance-sheet support, open-item status, and review completion.

Output: Close package with signoff

Management reporting

Reporting by the dimensions that reflect how the company earns money and consumes cash, with definitions kept consistent over time.

Output: Decision-ready reporting pack

Accounts-payable workflow

Invoice intake, coding, approval, payment preparation, vendor records, and segregation of owner approval from accounting execution.

Output: Controlled approval queue

Billing and receivables support

Invoice and collection workflow, aging, credits, deposits, write-offs, and escalation rules coordinated with the operating team.

Output: AR and collections view

Payroll and owner-activity accounting

Payroll journals, liabilities, benefits, reimbursements, distributions, contributions, and intercompany activity recorded and reviewed separately.

Output: Reconciled owner and payroll schedules

Tax and adviser handoff

Entity activity, fixed assets, owner transactions, planning actions, and support assembled throughout the year instead of reconstructed at filing time.

Output: Maintained tax-ready file

Compare the operating models

Bookkeeping vs. outsourced accounting vs. controller vs. in-house team

The right choice depends on responsibility and complexity, not simply transaction count. Compare who owns the close, who reviews the work, and what management receives.

Outsourcing accounting services for small business

What to outsource first: bookkeeping, then the close, then controller review

Outsourcing accounting services for a small business works best in layers. Each layer fixes a specific failure and produces the input the next layer needs. Skipping ahead to reporting or CFO work on top of unreconciled books wastes the fee.

01Bookkeeping first: every bank, card, loan, and payroll account reconciled monthly, transactions categorized to a stable chart of accounts, receipts and bills captured in one system. A simpler business may need only this layer; scope follows the work rather than a revenue threshold.
02The monthly close second: a calendar with a deadline, accruals and prepaids where they matter, balance-sheet schedules for debt, fixed assets, payroll liabilities, and owner activity, and a written list of open items with an owner.
03Controller review third: someone above the bookkeeper who checks the close, explains unusual changes, keeps the reporting dimensions consistent, and answers management questions before the numbers go to a lender, a partner, or the tax return.
04Payroll and payables coordination when there are employees or vendor volume: the accounting team reconciles what the payroll provider and bill-pay system produce, so liabilities and cash forecasts tie out.
05Coordinate tax planning with the close; add fractional CFO work when forecasting or a decision requires it. Projections, estimates, entity decisions, and cash forecasts are only as good as the reconciled data underneath them.

Back office accounting outsourcing

Back office accounting outsourcing: what moves out and what stays in-house

Back office accounting outsourcing means an outside team owns the recurring accounting workflows while the owner and staff keep the decisions and the customer-facing work. The split should be written down, because the failures happen at the handoffs.

Typically outsourced: transaction accounting, reconciliations, the monthly close, balance-sheet schedules, financial statements, payroll accounting, payables and receivables support, sales-tax and 1099 data preparation, management reporting, and the handoff to tax preparation and planning.

Typically kept in-house: approving bills and payroll, customer invoicing decisions, pricing, hiring, bank and vendor relationships, and any task that needs someone physically on site. An office manager or internal bookkeeper can stay in the loop with defined responsibilities; the outsourced team owns review and the close.

One-team versions of this, where the same firm runs the books, payroll coordination, and the tax return, remove the most expensive handoff: the year-end scramble to rebuild books for a preparer who has never seen them. That is the model Taxstra runs for small businesses, and the accountant services page describes the full scope.

Buyer checklist

How to evaluate an outsourced accounting proposal

Require enough detail to compare responsibility, review, timing, systems, deliverables, and change management, not only a monthly fee.

Responsibility map

List every recurring workflow and who prepares, reviews, approves, pays, and resolves exceptions.

Close acceptance criteria

Define the accounts reconciled, schedules delivered, review evidence, open-item rules, and management signoff.

Named service team

Identify who performs bookkeeping, controller review, reporting, meetings, tax coordination, and coverage.

Systems boundary

State which ledgers, banks, payrolls, billing tools, bill-pay systems, entities, and integrations are included.

Management output

See a sample package and confirm dimensions, commentary, KPIs, meeting cadence, and action tracking.

Scope-change method

Document onboarding, cleanup, new entities, transaction growth, special projects, and what changes the fee.

Strong fit

The owner needs dependable monthly financial statements, not transaction coding alone.
Several systems, entities, accounts, locations, projects, or revenue streams must be coordinated.
A bookkeeper exists but controller review and close ownership are missing.
The company needs accounting, tax planning, and return preparation to use the same data.
Management will provide approvals, source records, and operational context on a defined schedule.

Probably too early or the wrong service

The business has only a few simple transactions and the owner is comfortable with DIY books.
The immediate need is a historical cleanup rather than a recurring function.
Management wants reports but will not maintain billing, approval, payroll, or source-document discipline.
The company expects accounting to make operating approvals reserved for management.
The only requested service is annual tax-return preparation.

Implementation

From accounting diagnostic to a controlled recurring close

Onboarding maps the current process before changing systems or account structure. The first close then tests the design against real transactions, dependencies, and management questions.

Accounting-function diagnostic

Review entities, chart of accounts, systems, reconciliations, payroll, billing, payables, debt, reports, deadlines, users, and open problems.

Workflow and reporting design

Define the close calendar, responsibilities, approvals, integrations, schedules, reporting dimensions, review controls, and management package.

Conversion and first close

Clean the opening position, document exceptions, operate the first monthly cycle, and resolve differences between the proposed process and real operations.

Recurring close and improvement

Run the close, issue reports, discuss exceptions, coordinate planning, and improve the workflow as the company adds volume or complexity.

Questions business owners ask

Outsourced Accounting FAQ

What is included in outsourced accounting services?

A full scope can include transaction accounting, reconciliations, close management, financial statements, controller review, payables, billing and receivables support, payroll accounting, reporting dimensions, management commentary, tax-ready schedules, and adviser coordination. The engagement letter should state which workflows Taxstra operates and which remain with the client.

How is outsourced accounting different from outsourced bookkeeping?

Bookkeeping focuses on recording and reconciling activity. Outsourced accounting adds ownership of the monthly close, balance-sheet support, reporting design, review, workflow controls, and coordination with management and tax work. Some businesses need only bookkeeping; others need the broader function.

Will I still use QuickBooks Online?

QuickBooks Online is often part of the stack, but the system design depends on current software, integrations, entities, transaction flows, and reporting needs. A platform decision should follow the workflow diagnostic rather than precede it.

When will monthly reports be available?

The close deadline depends on source-system timing, bank and payroll availability, invoice and approval workflows, inventory or project complexity, and how quickly management answers exceptions. Taxstra establishes an agreed calendar and measures blockers rather than promising a date before reviewing the process.

Can Taxstra work with our internal bookkeeper or office manager?

Yes. An outsourced function can retain useful internal responsibilities while Taxstra owns review, close management, reporting, or selected workflows. The key is a written responsibility map so tasks, approvals, and escalation do not overlap or disappear.

Can accounting, tax planning, and CFO services be combined?

Yes. Reliable accounting is the foundation for planning and CFO work. A combined scope can connect the close, tax projection, cash forecast, management meeting, and return handoff while preserving clear preparation, review, and approval responsibilities.

Is outsourced accounting right for a small business?

It is when the owner needs reliable monthly numbers and does not want to manage a bookkeeper, a payroll provider, and a tax preparer separately. A business with simple activity may need only outsourced bookkeeping; the full accounting function makes sense once there are employees, multiple accounts or entities, lender reporting, or decisions that depend on current data.

What does back office accounting outsourcing include?

The recurring accounting workflows: reconciliations, the monthly close, balance-sheet schedules, financial statements, payroll accounting, payables and receivables support, management reporting, and the handoff to tax preparation and planning. Approvals, pricing, hiring, and customer relationships stay with the owner. The engagement letter should list which workflows the outsourced team operates.
