Part-Time Finance & Operations Assistant

Only Growth Agency PTY LTD – Melbourne VIC

Part-Time Finance & Operations Assistant
Remote | Melbourne, VIC | $40–$50 per hour | Flexible hours

Your Next Career Move Shouldn't Feel Like Just Another Job.
Imagine swapping the daily commute and corporate routines for a flexible, work-from-home opportunity where you can work directly with successful entrepreneurs and become an important part of a rapidly growing digital business.

At Numero, we're offering exactly that.

We're a young, ambitious and growing company operating in the exciting world of digital creators, social media and online marketing.

We're looking for a reliable, organised and detail-oriented Finance & Operations Assistant to help manage our invoicing, staff payments and day-to-day financial administration.

This is a part-time remote position, starting at approximately 10–15 hours per week, with the potential to grow into a full-time role as our company continues to expand.

If you're great with numbers, love keeping things organised and enjoy having the flexibility to work from home, we'd love to hear from you!

A Little About Us

Numero is a growing digital creator management agency specialising in content monetisation, digital marketing and creator growth.

We work with a diverse portfolio of online personalities, supported by an international team across marketing, sales, content and operations.

We're ambitious about where we're heading, but equally passionate about creating a positive, enjoyable working environment where great people feel valued.

We're now looking for someone to work closely with our founders and help manage the financial administration that keeps our business running smoothly.

What Will Your Day Look Like?

Your main focus will be ensuring our invoicing and staff payments are handled accurately, efficiently and on time.

Your key responsibilities will include:

Client Invoicing & Payment Tracking

• Prepare, issue and manage client invoices.
• Track incoming payments and follow up on outstanding invoices.
• Maintain accurate invoicing records and payment spreadsheets.
• Identify discrepancies and help resolve payment-related issues.

Staff Payments & Payroll Administration

• Prepare and coordinate regular payments for our international team.
• Calculate staff earnings, commissions, bonuses and payment adjustments.
• Review payment records to ensure accuracy before processing.
• Maintain organised records of staff payments and payment schedules.

General Finance & Administration

• Keep financial spreadsheets and internal records accurate and up to date.
• Assist with basic financial reporting and reconciliations.
• Support our founders with general financial administration.
• Identify opportunities to improve and streamline our existing processes.

Who Would Thrive in This Role?

We're not necessarily looking for someone with experience in our exact industry.

We're looking for someone who's reliable, detail-oriented and takes pride in getting things right.

You’ll ideally bring:

• Previous experience in invoicing, bookkeeping, payroll administration, accounts or a similar role.
• Excellent attention to detail, particularly when working with numbers and payments.
• Strong spreadsheet skills, including Excel or Google Sheets.
• Confidence managing invoices, payment records and financial calculations.
• Excellent organisational and time management skills.
• The ability to work independently and manage recurring weekly responsibilities.
• Strong written communication skills.
• A proactive attitude and willingness to learn.
• Availability to work remotely from Melbourne, Victoria.

Experience managing payments for international teams or working in a digital business is a bonus, but certainly not essential.

Above all, we're looking for someone we can trust to take ownership of their responsibilities, work accurately and consistently follow through.

Work From Home

Enjoy the comfort and flexibility of working remotely, without the daily commute.

Flexible Part-Time Hours

Start with approximately 10–15 hours per week, with the flexibility to manage your workload around agreed deadlines and payment schedules.

Potential to Grow Into a Full-Time Role
