Climate tech accounting

What is climate tech accounting?

Climate tech accounting is bookkeeping and financial reporting for companies building energy, climate and hardware products. It usually means capitalizing and depreciating equipment, tracking spend by program, pilot or grant, spreading long supplier contracts over time, and watching burn closely through long development cycles before revenue.

Each AI suggestion arrives with its reasoning and confidence. Fixed-asset and prepaid schedules wait for your sign-off, and nothing changes in a closed period, so investors and auditors get a clear trail.
