The complete guide to outsourced accounting for small businesses

Outsourced accounting means handing some or all of your finance work to an external team instead of employing people in house. Done well, it gives a small business the discipline of a proper finance function without the cost of building one.

This guide covers what can be outsourced, how the arrangement works in practice, and how to choose a provider you can trust.

What can be outsourced

Most finance work can be done by an external team. The most common services are:

Service	What it covers
Bookkeeping	Recording transactions, reconciling accounts, closing the month
Financial reporting	Monthly statements, management reports, budget versus actual
Accounts payable	Processing bills, preparing payment runs, reconciling vendor balances
Accounts receivable	Invoicing, applying payments, chasing overdue accounts
System implementation	Setting up or moving to new accounting or ERP software
Tax compliance	Preparing and filing returns, where the provider is qualified in that country

You do not have to outsource everything. Many businesses start with bookkeeping and add reporting or payables once the books are in order.

What stays with you

Outsourcing the work does not mean outsourcing control. You should always:

Own your accounting system and decide who has access to it
Approve and release payments yourself
Answer questions about transactions only you can explain
Make the business decisions the numbers inform

A good provider will be clear about this split from the start. We publish ours on our How we work page.

How it works day to day

A typical monthly rhythm looks like this:

During the month, transactions flow in through bank feeds and documents are shared through a folder or receipt app.
At month end, the team reconciles every account and sends you a single list of open questions.
By an agreed date, the month is closed and reviewed by a qualified accountant.
On report day, you receive your financial statements, often with short commentary.

Communication is usually by email or messaging for quick questions, plus a short monthly call to review the numbers.

What it costs

Fees depend mainly on:

The number of transactions each month
The number of bank, card and loan accounts
How many entities or locations you have
The reports you need and how often
Whether your books need a cleanup first

Most providers charge a fixed monthly fee for an agreed scope, with one off fees for catch up work. Ask for the scope in writing so you know exactly what is included.

Questions to ask before you choose

Who will do my work, and what are their qualifications? Look for professionally qualified accountants, such as ACCA or CA, leading the work.
Who reviews it? Every close should be checked by a second, qualified person.
Which software do you work in? The provider should work in your system, not move you to theirs.
How do you protect my data? Expect a confidentiality agreement and access you control.
What do I receive each month, and when? You want a fixed list of deliverables and dates.
How do we communicate? Find out who your contact is and how quickly they respond.
What happens if I want to leave? Your books should stay in your system, with documentation of how they were kept.

Common mistakes to avoid

Choosing on price alone. Cheap bookkeeping that needs redoing at year end is expensive.
Starting without a cleanup. If your books are behind, fix that first, or every month inherits old errors.
Not reading the reports. The value of outsourcing comes from using the numbers. Book the monthly review call.

Is it right for you?

Outsourced accounting suits businesses that need accurate books and regular reporting but not a full time finance team. It is especially useful when the owner is currently doing the books, when a bookkeeper has left, or when the business is preparing for growth, investment or an audit.
