AI finance platforms compared

A batch ledger collects work and posts it in cycles. That is fine when volumes are low and one entity carries most of the activity.

It gets expensive at group level. Entities close at different speeds, intercompany waits for both sides, and the consolidated view is rebuilt each month.

A live ledger keeps the group current. The value is not speed for its own sake. It is that an agent can act on today's position rather than last week's snapshot.

When you demo, ask to see the group P&L on day nine of the month rather than after close. That answers the question faster than a feature list.

Start with intake. Supplier invoices arrive by mail or upload, card spend produces receipts, and customer invoices go out on a schedule. Every platform here reads invoices with AI; the difference is what the read produces.

On NetSuite, Intelligent Bill Capture extracts fields and you review on a scanned bill screen before a vendor bill is created. Three-way match and approvals are the existing NetSuite mechanics.

On Business Central, the Payables Agent monitors a mailbox and creates drafts for a supervisor. It stops when it cannot identify a vendor, and it does not silently post.

On Sage Intacct, the 2026 R1 AP automation extracts invoice PDFs, suggests coding, matches PO lines, and predicts tax into a draft bill that staff review.

On Light, AI reads bills and receipts including line items, tax, and terms, approvals run in Slack or Teams, and agents carry AP through to the ledger with finance reviewing the result.

Then the group layer. Consolidation, intercompany, and multi-book determine how many hours the team loses each month. On Light this is the core design; on the suites it depends on how the entities and books were configured at implementation.

Then revenue. If you bill subscriptions or contracts, check whether revenue recognition is native, and what happens when a contract spans entities or books.

Then payment. Light includes native bill pay from the company's own bank in more than eighty countries. On the other platforms, payment is usually a bank integration or a partner rail, which adds a reconciliation step.

If the company holds stock, builds product, or runs commerce operations, choose the suite. NetSuite or Business Central will carry finance well enough and carry operations too.

If the company is US-centric with heavy audit and CPA expectations, Sage Intacct is the comfortable answer and the bench of people who know it is deep.

If the company is finance-led, has two or more entities, and does not need inventory, Light is the shape that removes work rather than drafting into it. Cloud-only in AWS EU, from $35,000 per year, usual fit 30 to 5,000 employees. Named customers include Tillo, KeyShot, and Alva Labs.

If the company is a single entity doing straightforward bookkeeping, none of these are right. Stay on Xero, QuickBooks Online, or Fortnox until a second entity appears.

Load one real month of supplier invoices, including the ugly ones with multi-line tax and a missing PO.

Run a real approval chain with real approvers, in the tool they actually use every day.

Do an intercompany transaction between two entities and watch what the group view does.

Close a period and count the manual journals. That count is the comparison.
