Join fiskaly - Help Us Simplify Receipts for Millions

Millions of people interact with fiskaly every day, even if they don’t realize it. As a B2B company, we power the retail technology behind digital receipts and secure, legally compliant transactions.

Job Details

• Role: Working Student / Billing Support Associate – Finance (all genders)
• Location: Vienna (Hybrid) or Berlin (Hybrid)
• Hours: 15–20 hours/week, part-time (ideal alongside your studies)
• Language: German (C1) & English (B2/C1)
• Salary: €1,300 – €1,500 gross/month for 20 h/week

By making receipts tamper‑proof through digital signatures, we help fight tax fraud. And with our paperless receipt solution, we offer consumers a modern alternative while helping merchants streamline their operations.

Sure, our solutions sound complex but our mission is simple: make receipts easy for everyone.

The Role

Billing has moved into Finance, and we are looking for someone who wants to own it. As our Billing Support Associate, you are the first point of contact when a customer has a question about an invoice: “Why was I charged for this?”, “Can you send me a copy?”, “We paid twice.” You handle these tickets from start to finish, work closely with Accounting, Sales, Data and Customer Support, and make sure our customers understand exactly what they pay for – and why.

This is not a “just answer tickets” job. You will see patterns nobody else sees, and we expect you to turn them into better processes, clearer templates and fewer tickets. If you are studying business, accounting or something similar and want real responsibility in a scaling SaaS company, this is your role.

What You’ll Do

• Own the Billing Inbox in Zendesk: Handle incoming billing tickets (invoice questions, copies, corrections, credit notes, payment allocation) from our customers in Germany, Austria, Spain, Italy and Sweden – accurately, friendly and on time.
• Investigate & Resolve: Check contracts, usage data and invoices in our billing tools, find out what happened, and give the customer a clear answer.
• Corrections & Credit Notes: Prepare invoice corrections and credit notes for review by Accounting and make sure the changes are documented properly.
• Dunning Support: Support our collections process – answer questions about reminders, coordinate payment plans with Accounting and keep the receivables clean.
• Knowledge Base: Maintain and improve our customer‑facing billing explanations and internal FAQs, so the same question doesn’t have to be answered twice.
• Process Improvement: Track recurring ticket types, report them to Finance and Product, and help us fix the root cause instead of the symptom.

What You Bring

• Studies: You are enrolled in a Bachelor’s or Master’s programme (business administration, accounting, finance, economics or similar) and available 15–20 hours per week.
• Customer Mindset: You like helping people, stay calm when someone is annoyed about an invoice, and write clear, polite emails in German and English.
• Numbers Don’t Scare You: You understand how an invoice, a credit note and a payment relate to each other. First experience in accounting, billing or customer service is a plus, not a must.
• Structured & Reliable: You keep track of open tickets, follow up, and don’t let things fall through the cracks.
• The Tech Mindset: You are comfortable with Google Workspace / MS Office, learn new tools quickly, and are curious about how automation and AI can make support faster.
• Languages: German (C1) and English (B2/C1) for our customers and internal communication. Spanish or Italian is a nice bonus, not a must.

What We Offer

• A team that values output over hours. We plan around your lecture schedule and exam periods.
• Flexible working hours and a hybrid setup in Vienna.
• Real ownership from day one and insight into the finance operations of a scaling and fast growing international SaaS company.
• Mentoring by our Accounting team and the option to grow into a permanent Finance role after your studies.
• Hardware of your choice (Windows/Mac).
• A company culture that is open, direct, and pragmatic.
