Expanding your clean energy operations? Manual invoicing may be slowing your growth

Written by Power Factors | Jun 26, 2025 2:00:50 PM

If you’re managing a renewable energy portfolio that’s expanding into new markets, invoicing is no longer just an administrative task. It's a critical function that directly shapes your company’s financial health, contract performance, and ability to scale. 

Every new region adds complexity: new tax rules, currencies, and different requirements for contract structures, from power purchase agreements and land leases to operations and maintenance services. And with so much at stake, invoicing needs to be accurate and on time to satisfy off-takers, regulators, and auditors. 

Relying on manual invoicing processes only adds to the challenge, taking up to 60 percent longer and increasing the risk of costly errors with every invoice. 

The pressure on finance teams 

Despite rapid expansion, most finance teams are still using the same tools that worked when their operations were smaller and limited to a single region. Tools that were never built to handle multi-country tax logic, currency conversion, or cross-border compliance. 

It’s understandable — companies have rightly focused on scaling operations and increasing revenue, while many back-office processes are left to “make do” with existing tools. 

But every new region multiplies complexity and risk, leaving finance teams stuck managing those challenges with workarounds like: 

  • Pulling financial data from disconnected systems 

  • Managing tax rules manually in spreadsheets 

  • Reformatting invoices and PDFs for each region 

  • Double-checking tax codes and relying on manual reviews to catch errors 

The inefficiencies of manual invoicing 

Manual processes do more than waste time. They put strain on finance and accounting teams, complicate operations, and create inefficiencies that add up to real costs:  

  • Delayed collections that impact cash flow 

  • Higher risk of tax penalties and expensive rework 

  • Reliance on costly external consultants for complex tax handling 

And as your portfolio grows, these challenges only multiply, making it harder to expand without adding headcount or increasing risk.

The measurable difference 

The impact of automating invoicing with Unity Invoice Management is measurable. Companies that once struggled with slow processing, tax errors, and expensive stopgaps are now seeing real results: 

A U.S.-based solar IPP operating across California, Texas, and New Jersey reduced invoice processing time by 60 percent and avoided over $150,000 annually in tax penalties by automating state-specific compliance. 

A European wind developer managing 1.2 GW across Spain, France, and Germany saved more than €200,000 each year through automated VAT handling, reducing reliance on consultants and avoiding costly rework. 

These are the kind of results that happen when finance teams adopt a platform purpose-built for the growth and complexity of global renewable energy operations.
