Outsourced Accounting or an In-House Accountant?

Outsourced Accounting or an In-House Accountant?

I hear this question almost every month from owners of small and medium businesses: should we hire an accountant or hand the work to a firm? This article compares both options across true cost, tax risk and management control, and explains the hybrid model that works best for most companies.

First define what you are outsourcing

"Accounting" is not one job. It is at least five layers, each with a different skill requirement and risk profile:

  • Daily recording: journal entries, purchases, sales, receipts and payments.
  • Periodic statutory filings: payroll and insurance lists, VAT, quarterly transaction reports, electronic invoice submission.
  • Period close and reporting: adjustments, costing, financial statements.
  • Tax defence: preparing submissions, attending assessments and dispute boards.
  • Management advice: profitability analysis, budgeting, pricing decisions.

Most companies believe they are comparing an accountant with a firm, when in fact they are comparing different layers.

The true cost of an in-house accountant

Any comparison based on monthly salary alone reaches the wrong conclusion. Include these items:

Cost component Note
Monthly salary and allowances Basis for everything else
Statutory year-end benefits Roughly two months of salary per year
Employer social security share A percentage of covered pay under the Social Security Act
Leave and absence About one month a year with no output
Workspace and equipment Desk, computer, software licence
Training Tax rules change frequently
Turnover risk Vacancy period and knowledge transfer cost

My rule of thumb: the annual cost of a full-time accountant is roughly 15 to 17 times monthly salary, not 12. And if that person is your only accountant, a second risk appears — segregation of duties disappears, because the same person records, reconciles and reports.

Concentrating recording, control and payment in one person is the most common internal-control weakness in small companies. Whichever model you choose, keep recording separate from payment approval.

The true cost of outsourcing

Outsourcing is normally priced as a monthly fee based on document volume and scope. The essential discipline is to compare identical scope. If the contract excludes audit defence, tax return preparation and year-end close, price those separately and add them.

Items commonly outside the base fee: preparing a defence and attending dispute boards, audited financial statements, inventory counts, new software implementation, and correcting prior-year books. Agree on them in advance.

Comparing the three options

Criterion In-house Full outsourcing Hybrid
Cost at low volume High Low Medium
Cost at high volume Medium High Medium
Day-to-day availability High Medium High
Breadth of expertise Limited to one person Team-based Team-based
Continuity during leave High risk Covered Low risk
Segregation of duties Weak if single-handed Good Good
Knowledge of operations Excellent Medium Good
Tax defence capability Variable Usually strong Strong

The hybrid model

For most mid-sized companies the best structure is one internal person handling daily recording, inventory, invoicing and collections, with an external adviser or firm doing monthly review, statutory filings, period close and defence. Operational knowledge stays inside, a second pair of eyes reviews the work, and someone with comparable case experience is available when an assessment arrives.

Two things make it work: shared software with simultaneous access, and a written calendar of obligations. On choosing software that allows this, see the accounting software selection guide.

When outsourcing is the wrong answer

  • Complex, real-time operations such as high-turnover retail or multi-stage manufacturing with work in progress.
  • Businesses needing daily financial decisions with someone immediately available.
  • Companies whose master data is already chaotic; clean it up first, or outsourcing simply relocates the mess.

Provider selection checklist

  1. Ask for proven experience in your industry and look at sample reports.
  2. Ask how many people will work on your file and who covers absences.
  3. Get the scope, and everything outside it, in a written list.
  4. Fix delivery dates: monthly close by which day, quarterly reports by which date.
  5. Check their record in assessment meetings and dispute boards.
  6. Clarify software and data ownership — the data must be yours.
  7. Include confidentiality and, if relevant, exclusivity against direct competitors.
  8. Write the exit process and full handover of records.
  9. Make the provider liable for penalties caused by its own delay or error.
  10. Set a three-month trial with defined evaluation measures.

Do not treat the handover clause as boilerplate. The most expensive situations I have seen involved companies that lost full access to their own electronic records when a contract ended.

One tax point that does not change

Responsibility for tax obligations rests with the taxpayer and the directors regardless of who does the work. Even under full outsourcing, the manager should see the obligations calendar and receive submission receipts. Early-stage obligations are covered in the post-registration compliance checklist, and what matters during an assessment in tax audits and appeals.

If you would like an assessment of which model fits your document volume and structure, I am glad to work through it with you.

Key takeaways

  • Decide which layer of accounting you are outsourcing before comparing prices.
  • An in-house accountant costs roughly 15 to 17 monthly salaries per year, not 12.
  • Comparisons are only meaningful at identical scope; price tax defence separately.
  • The hybrid model gives most mid-sized companies the best balance of cost, control and expertise.
  • Put data ownership, staff cover and exit terms in the contract.

Frequently asked questions

Which companies suit outsourced accounting?
Small and medium businesses whose monthly document volume does not fill a full-time role, and companies that need varied tax expertise only periodically. With dozens of daily documents and several active warehouses, a hybrid arrangement usually works better.
Is outsourcing cheaper than hiring?
At low to moderate volumes it usually is, because fixed salary, insurance, year-end benefits, workspace and training costs disappear. The comparison is only valid when both sides cover the same scope; a cheap contract that excludes audit defence is not comparable to a full-time accountant.
Who is responsible if a tax filing is wrong?
Legal responsibility for tax obligations always rests with the taxpayer and the company's directors and cannot be contracted away. You can, however, include a written provision making the service provider liable for penalties caused by its own delay or error.
What must stay inside the company?
Payment approval, custody of cheques and negotiable instruments, sales invoicing and inventory control. Outsource recording, reporting and analysis, never authority over company assets.
