Finance that scales across borders

Light is the AI-native finance platform built for companies growing internationally. Greenstep is the Light partner that sets it up, runs it and keeps your accounting compliant in every market you enter.

New countries, same finance team

Every new market adds entities, currencies, tax rules and reporting requirements. On traditional systems, that usually means more manual work and more people.

Light takes a different approach. All your entities, currencies and ledgers sit on one real-time platform, and automation handles the routine work. Greenstep brings the local accounting expertise to make it work in each country. Your finance team can support a bigger business without growing at the same pace.

The finance platform we recommend to growing international companies

Light combines AI-native automation with the finance controls companies need as they expand into new markets.

AI-native finance

AI is built into daily workflows. Light reads incoming invoices, handles line items, local tax codes and currencies, and posts them. Approvals run through Slack or Teams, so your team can approve from wherever they work. The result is less manual processing and a faster month-end close.

Fast time to value

Most clients are live in 8 to 12 weeks, with automation running from day one. Your team keeps working normally while we handle the switch.

Built for international growth

Light is multi-entity and multi-currency from day one. Every legal entity sits on the same platform, currency conversion is automatic, and you get a consolidated view across the group. Adding a new country doesn’t mean adding a new system.

One finance platform

General ledger, accounts payable, accounts receivable, expenses and payments in one place. Light reads your contracts, builds revenue schedules, generates invoices and manages deferred revenue. Reports load in under half a second, and the immutable ledger leaves a clear audit trail for auditors and investors.
