Zusammenfassung

trawa is seeking a Billing Manager to own the invoicing end-to-end for our growth-stage energy-tech business. You will design processes, manage complex pricing, and ensure data quality from contracts to accounting.

You will lead the rollout of a scalable invoicing architecture, automate recurring steps, and collaborate with Sales, CS, and the Tech/Data teams to remove bottlenecks and shorten time-to-invoice. Fluency in English and German is required.

Qualifikationen

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

• Systems thinker with attention to detail in ticket/invoice corrections.
• Advanced Excel/Sheets skills; ability to document models clearly.
• Strong stakeholder management across finance and operations.
• Ownership mindset; proactive in taking on tasks beyond defined roles.
• Business fluency in English and German (written); speaking is a plus.

Aufgaben

• Own daily invoicing processes to customers: quality, completeness, and timing.
• Reduce ticket backlog through prioritization, root-cause analysis, and execution.
• Ensure complex billing logic (PPA, spot, futures, EEG, grid fees, taxes) is reflected in invoices.
• Own invoicing KPIs: on-time rate, error rate, ticket aging, time-to-invoice.
• Help design and roll out a scalable invoicing architecture from manual to automated.
• Automate recurring process steps and document everything for audit readiness.
• Direct customer communication on invoicing questions in German and English.
• Coordinate with Sales and CS to ensure upstream data quality (contracts, prices, delivery points).
• Collaborate with Tech/Data on consumption data, time series, and accruals.

Jobbeschreibung

Billing Manager

Permanent employee · Full-time · Berlin (HQ)

Our Mission For You
Own the invoicing engine of a hyper-growth energy-tech company. Your work directly protects our cash flow and keeps our growth engine running. Invoicing directly affects our cash flow in the millions. This role is a lever, not a cost center.
trawa enables mid-sized companies to access green, intelligent energy. We're a hyper-growth company with strong team growth, rising invoice volumes, and increasing complexity per invoice. Individual contracts, PPAs, spot, futures, EEG direct marketing, grid fees, taxes: every customer segment is a small puzzle. Today, that puzzle is solved mostly manually, and it needs to move to the next level.
You'll build order out of that complexity. You'll jump into individual invoices when it matters. At the same time, you'll design the process that makes those individual jumps unnecessary. You'll be part of our Billing Tool Rollout and help prepare invoicing for our ERP migration. This is a hands-on role for someone who wants to own the operation, not just manage it.
What You'll Own

Own Invoicing End to End

• 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

Build Scalable Processes

• 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

Stakeholder & Customer Communication

• 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

Data Quality & Handover to Accounting

• 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

Who You Are

Must-haves

• 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

Nice-to-haves

• 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)

Your First 90 Days

Month 1: Land & Understand

• 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.

Month 2: Stabilize

• 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.

Month 3: Build

• 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.

Why trawa?

• 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
