Capture inside the ledger
Rossum reads and validates invoices and posts them into SAP, Coupa, NetSuite, Workday or Dynamics. Light captures invoices natively in its own AP, so the document and the ledger entry are one record.

Pay the approved bill from the books
With Rossum the payment run stays in the ERP or the bank. Light pays approved bills from the ledger on local rails in 80+ countries.
- 02
Close and consolidate in one place
Rossum hands the posted invoice to the ERP, where close, consolidation and reporting happen. Light consolidates every entity as transactions post, with drill-down to the source document.
When to choose Light
- 01
The ledger is included
Light is the system of record: spend, AP, AR and the general ledger in one platform, with no ERP decision left open.
- 02
Pay suppliers from the ledger
Approved bills pay from your own bank accounts on local rails in 80+ countries.
- 03
Less close to run
Consolidation posts as transactions happen, so the period end has less to reconcile in the first place.
