Light – Accounting that works while you sleep

A new generation of accounting software, that's built for AI, not adapted for it

Most accounting platforms were built for manual entry and retrofitted with "AI features". Light was designed from scratch as an AI-native system, with real-time reporting and automation at every layer.

Automated accounts payable

AI extracts and posts invoice data, handles fine items, tax codes and multi-currency, including approval workflows via Slack and Teams.

Automated accounts receivable

Light reads contracts, creates revenue schedules, generates invoices automatically and handles deferred revenue accounting end-to-end.

Real-time general ledger

Built on an in-memory HTAP database, reports load in under 500ms. The immutable ledger creates an audit-proof trail – no entry can be silently edited.

Multi-entity, multi-currency

One unified view across all your legal entities with automatic currency conversion and consolidated reporting means no more Excel consolidation.

The future of accounting is already here.

Finance leaders who move to AI-native platforms now will close faster, report in real-time and redirect their teams to work that actually matters – analysis, strategy and growth.

Greenstep helps you make the switch without disruption.

From legacy spreadsheets to AI-powered finance in four steps

We review your current systems, entity structure and reporting needs. We confirm whether Light is the right fit, and explain exactly why.

2. Setup & data migration

Our team configures Light for your chart of accounts, entities, currencies and approval flows. Historical data is migrated cleanly.

3. Go-live & automation

We activate AR, AP and GL automation. Your team gets hands-on training and Greenstep stays close through the first close cycle.

4. Ongoing accounting & support

Greenstep’s accountants run your day-to-day bookkeeping and reporting on Light – combining expert humans with AI efficiency.
