Finance & Billing Operations Specialist (m/f/d) | Part-Time | Fully Remote (EU)

Finance & Billing Operations Specialist Who Keeps Our Numbers Running Smoothly

Part-Time (20-25 h/week) | Remote | HQ: Munich

We’re looking for someone who enjoys bringing order to contracts, invoices, and payments in a structured way.

Why You’ll Enjoy Working Here

Fully Remote (EU-based)

Work from anywhere in the EU. No relocation, no office politics, no pretending to enjoy open spaces.

Flexible Working Hours

We care about outcomes, not clock-watching. Organize your working hours in a way that actually fits your life.

Competitive Compensation

A salary package aligned with your experience and skills, with transparency and no guesswork.

Stability You Can Rely On

We work with long-term marketing agencies and e-commerce companies across the EU. No short-term hype, no client roulette.

Clean Processes, Not Chaos

Finance and billing processes are documented, digital, and structured. You won’t be hired to “fix a mess” but to keep things running smoothly and improve them.

Real Impact, Low Noise

You work directly with the CEO, have clear ownership, and your work actually matters. Fewer meetings, more substance.

Your Profile

• Experience. At least 2–4 years of hands-on experience in finance operations, billing, preferably in a B2B setup.

• Process & Precision. Highly structured, detail-oriented, and accountable for data accuracy, invoicing, and on-time payments.

• Tools & Systems. High confidence working with CRM, billing, and payment tools is a must. Experience with HubSpot, Easybill, Agicap, Stripe, or similar systems is strongly preferred.

• Contracts & Payments. Solid understanding of commercial contracts, invoicing logic, and payment flows, including recurring billing and service periods.

• Customer Communication. Professional, friendly, and solution-oriented communication with customers on payment topics.

• Tax & Compliance. Familiarity with German and EU tax requirements.

• Languages. Business-fluent English and German (C1 level).

• Education. A bachelor’s degree in finance, accounting, business administration or similar.

• Remote Readiness. Comfortable working independently with a high level of ownership.

What You Will Do

• Manage and maintain customer, contract, and billing data across systems.

• Oversee approximately 250 outgoing invoices per month (e.g. via Easybill).

• Handle contracts, contract changes, and cancellations.

• Monitor incoming payments via bank and payment providers (e.g. Stripe) and assign them correctly.

• Spot missing or delayed payments and follow up proactively.

• Handle payment follow-ups in a professional, friendly, and solution-oriented way, with a focus on maintaining strong customer relationships.

• Collaborate closely with external accounting and tax advisors.

• Support the implementation and optimization of finance, billing, and CRM tools.

• Maintain a clear, reliable contract and billing database.

You don’t need to be a CFO, but you do know how finance operations work.

If you like structure, ownership, and flexibility, without the chaos, this role is for you.
