Your Bookkeeping Team. Without the Extra Hire.
Keeping your books accurate takes time, consistency and attention, but hiring someone internally isn’t always the right answer. You may not have enough work for a full-time bookkeeper, or you simply don’t want another person to recruit and manage.
Simplex provides Outsourced Bookkeeping Services that give your business reliable bookkeeping support without building an in-house finance team. We’ll keep your records organised and up to date, reduce the admin on your plate and give you more time to focus on running your business.
Skip the Recruitment
Get ongoing bookkeeping support without having to recruit, train and manage another member of staff.
Everything Up to Date
Keep your financial records organised throughout the year instead of facing a bookkeeping backlog when a deadline approaches.
Support Beyond the Books
Your bookkeeping sits within an accounting firm, so when wider financial or tax questions arise, We’re here to help.

Bookkeeping Needs Doing. You Don’t Need to Do It.
As your business grows, so does the financial admin behind it.
There are more transactions to process, more receipts and invoices to deal with and more records that need to stay accurate.
Eventually, doing the bookkeeping yourself stops being a good use of your time.
With Outsourced Bookkeeping Services, Simplex takes responsibility for the agreed bookkeeping work without you needing to build an internal bookkeeping function.
You get the support your business needs while you get your time back.
A Bookkeeping Function That Fits Around Your Business
Outsourcing doesn’t mean losing visibility or control.
It means handing repetitive financial admin to people who know how to deal with it, while you stay focused on the business.
We can help with:
✅ Recording and categorising transactions
✅ Bank and account reconciliations
✅ Processing receipts and purchase invoices
✅ Maintaining accurate financial records
✅ Keeping your bookkeeping organised throughout the year
We’ll agree a straightforward process around your business, so everyone knows what needs to happen and when.

“Simplex are super easy to work with. I love that I have a portal to track all documents and paperwork that need my attention. Everything else just seems to run in the background so I can focus on my business”
Jordan, Design

Why Hire When You Can Outsource?
Taking on an employee comes with more than a salary.
There’s recruitment, onboarding, training, payroll, holiday cover and the ongoing responsibility of managing another person.
For many businesses, outsourcing bookkeeping can provide a simpler alternative.
You get regular bookkeeping support without needing to create another internal role.
And because your bookkeeping is handled by Simplex, it connects naturally with the wider accounting and tax support your business may need.
One relationship. Less duplication. Fewer things for you to manage.
Your Books Shouldn’t Depend on Your Spare Time
Bookkeeping shouldn’t take over your evenings.
A customer calls, a team member needs help, and there is work to deliver, so suddenly another month has passed before bookkeeping is even thought about.
Outsourcing creates consistency by making bookkeeping part of an established process rather than something that depends on finding a spare evening to catch up.
And when you need help, Simplex is easy to reach. Clients receive unlimited calls, WhatsApp messages and emails at no extra cost, with a 48-hour response guarantee. We’re available from 9 am to 6 pm.

“Simplex have been with our company from the start and are a crucial linchpin in our Operations. They are organised, methodical, quick to respond to needs and queries and ultimately professional while maintaining a friendly, caring approach. We couldn’t ask for more.”

The cost of outsourced bookkeeping depends on your transaction volume, business complexity and how much support you need. Some providers charge hourly, while others offer fixed monthly packages. For small businesses, monthly pricing can make costs easier to manage while ensuring the books stay up to date throughout the year. We tailor our outsourced bookkeeping service around your business, giving you reliable financial records without the cost and commitment of employing an in-house bookkeeper.
An outsourced bookkeeper manages your day-to-day financial records without being employed directly by your business. This can include recording transactions, reconciling bank accounts, organising purchase and sales information and keeping accounting software up to date. Depending on your package, support may also cover VAT and financial reporting. We provide bookkeeping remotely, giving you accurate, organised records and more time to concentrate on running your business.
How much you should pay for bookkeeping depends on the amount of work involved rather than simply the number of hours spent. Transaction volumes, VAT registration, accounting software and the condition of your existing records can all affect the cost. A fixed monthly bookkeeping service can provide better certainty than an hourly rate. It also means your bookkeeping is handled consistently, helping you maintain accurate records and understand your finances throughout the year.
AI and accounting software are automating more bookkeeping tasks, but they do not remove the need for accurate financial oversight. Technology can speed up data entry, receipt processing and bank reconciliation, but transactions still need to be checked and unusual items handled correctly. We use modern accounting technology to make bookkeeping more efficient while providing the human oversight and accounting knowledge needed to keep your records reliable and useful for making business decisions.
