Billing Manager

Permanent employee · Full-time · Berlin (HQ)

• Own daily invoicing processes to trawa customers: quality, completeness, timing

• Reduce and eliminate our current ticket backlog through prioritization, root-cause analysis, and systematic execution

• Ensure complex billing logic (PPA, spot, futures, EEG direct marketing, grid fees, taxes) is correctly reflected in every invoice

• Own the invoicing KPIs: on-time rate, error rate, ticket aging, time-to-invoice

• Be part of designing and rolling out a scalable invoicing architecture, from today's manual setup to a standardized and automated solution

• Automate recurring process steps

• Document everything: reproducible, hand-off-ready, audit-ready

• Direct customer communication on invoicing questions, in writing (German and English)

• Partner closely with Sales and Customer Success to secure upstream data quality (contracts, prices, delivery points)

• Partner closely with our Tech/Data team, where consumption data, time series, and energy accruals are your input

• Establish escalation paths and priority logic with Sales and CS, so edge cases don't block the standard process

• Ensure invoicing data flows cleanly into accounting, as the interface to our accounting team

• Contribute to month-end close: clean invoicing cut-off, documented open items, accruals-relevant data ready on time

• Audit-readiness from an invoicing perspective: process documentation, invoice-level traceability, controls

• 3+ years in Billing, Order-to-Cash, Finance Operations, or similar operational Finance roles

• Scale-up experience, with at least one station at a fast-growing company. You've worked without a clean ERP, with ambiguous processes, in a team being built as it runs

• B2B billing with complex pricing models, not SaaS flat-rate. You've handled individual contracts, volume-based logic, or formula-driven pricing

• Proven high-output track record. You've personally delivered and you can point to a moment where you built or saved a critical process

• Systems thinker with a detail obsession. You see the pattern behind ticket or invoice corrections

• Excel/ Sheets power user. You build models others can't unpack, and you document them so they can

• Strong stakeholder management

• Ownership mindset. You take things on without asking whether it's "in your role"

• Business fluent in English and German (written); speaking is a big plus

• Energy or utility experience

• Hands-on experience with a Billing Tool rollout or ERP implementation

• SQL, Python basics, or hands-on experience with AI tools (Claude, Langdock, n8n)

• Understand our business model, the German energy market basics, and our billing complexity. Understand what drives our corrections rate. Build relationships with the most important stakeholders.

• Keep invoicing running stably while spotting optimization opportunities. Define clear ticket priorities and escalation paths with Sales and CS. Ship first quick wins in automation and process design. Define and start tracking your KPIs: error rate, ticket aging.

• Deliver a target process architecture for improvements to our current invoicing processes. Actively and proactively reduce time-to-invoice and corrections rates. Present your automation and process roadmap to the finance leadership team.

• Real ownership from day one. You build the invoicing function that unlocks trawa's growth

• Direct collaboration in a complex stakeholder set-up, with direct contact to our finance leadership team

• A uniquely complex problem space at the intersection of energy, tech, and finance

• An AI-first Finance team that embraces new tools and ways of working

• Accelerated career growth in a scaling environment with massive scope

• Flexible working, 30 vacation days, L&D budget, competitive compensation, VSOPs (share package), meal vouchers, Urban Sports membership, and a vibrant office culture
