About the role
Accounts Receivable Accountant
Permanent employee · Full-time · Berlin (HQ)
Our Mission For You
Own the process that turns invoices into cash, and shape how trawa's Finance function scales with our customer base.
trawa enables mid-sized industrial and commercial companies to access green, intelligent energy. We're in a hyper-growth phase in one of the most complex markets in Germany. It's a rare moment to join: the foundations are being built right now, the problems are real, and the room to shape how Finance runs at scale is wide open.
This is one of the most critical roles in the company. Cash is what enables trawa's growth, and you own the process that protects it. Every reconciliation you close, every overdue account you resolve, every dispute you clean up feeds directly into how fast we can move.
As our Accounts Receivable Accountant, you'll own the end-to-end AR and collections process. You'll be the person customers talk to when something on an invoice isn't clear, and the person internally who makes sure open items don't stay open. You'll work closely with Customer Success, Business Operations, and our Finance team.
If you're excited by ownership, an AI-first way of working, and building something that actually matters, this is your role.
What You'll Own
Collections and Dunning
Own the collections cadence end-to-end: monitor AR aging, prioritise the highest-impact accounts, and drive them to resolution via email and phone.
Reduce DSO measurably. You set the pace, we give you the tools and the mandate.
Manage our dunning process reliably and with the right tone: firm on cash, respectful of the customer relationshipDebitorenbuchhaltung und operative Prozesse.
Reconciliation and Cash Application
Reconcile incoming payments against open invoices, investigate and resolve unapplied cash, short-pays, and discrepancies.
Run structured reconciliations reliably, and independently drive ad-hoc analyses for complex payments or edge cases.
Support month-end close with AR reconciliations and clean aging reports.
Ticket Ownership and Customer Interaction
Take ownership of our AR ticket queue, which is currently high-volume and one of the most visible pain points across the company. You get on top of it, categorise what's coming in, and resolve the majority of tickets directly.
Be the go-to Finance contact for customers on all relevant topics: invoicing, payments, and account requests.
Work closely with Customer Success and BizOps to resolve customer issues end-to-end and make sure Finance topics don't get stuck between teams.
Who You Are
Must-haves
3+ years of experience in Accounts Receivable, Collections, or Credit Control, or a comparable Finance role. Ideally in a high-volume and complex B2B environment
Solid understanding of AR processes: dunning, cash application, reconciliations, and month-end AR work.
Confident with customers in writing and on the phone. You can be firm on cash without damaging the relationship.
Strong ownership mindset. You don't wait for someone to flag a problem. You spot it, dig into the root cause, and drive it to resolution across stakeholders.
Structured, analytical, and detail-oriented. You keep complex open items straight without losing the bigger picture.
Business fluent in English and solid written German (customer correspondence in German needs to work reliably). Spoken German is a strong plus but not required.
Comfortable in the standard office and analytics toolset (Excel or Google Sheets) and able to navigate independently.
Nice-to-haves
A degree in Accounting, Finance, Business, or a comparable field, or a solid vocational qualification (e.g. Bilanzbuchhalter:in IHK, Steuerfachangestellte:r, kaufmännische Ausbildung). We care about what you can do, not the badge on your CV.
Experience with AI-powered reconciliation tools or modern ticketing systems.
Genuine curiosity for AI and automation. Bonus if you've already used Langdock, Claude, or similar tools to speed up your own work.
Experience in a fast-growing start-up or scale-up environment.
Your First 90 Days
Month 1: Understand
