AI finance transformation

A copilot suggests. It drafts a bill, writes a variance sentence, or answers a question about a report. The work still queues for a person.

An agent runs a job. It works through AP, AR, reconciliation, or the close on the ledger, and finance reviews the outcome instead of assembling it.

Both are useful. They are not interchangeable, and a finance transformation built on the wrong assumption will miss its numbers.

The practical test in a demo is simple. Ask who posts, and ask what happens when nobody opens the queue for two days.

Start by writing down the baseline. Days to close, share of invoices touched by a human, hours spent on consolidation, and how many receipts are still missing at month end.

Then look at intake. On all four systems, AI reads supplier invoices. NetSuite uses Intelligent Bill Capture, Business Central uses the Payables Agent from a mailbox, Sage Intacct extracts invoice PDFs in the 2026 R1 AP automation, and Light reads bills and receipts on the live ledger.

Next, look at coding and approval. The copilot systems produce a draft that lands in a queue. Light routes approvals into Slack or Teams and keeps the entry on the live ledger rather than in a staging area.

Then reconciliation. NetSuite has AI-assisted reconciliation with a user driving. Sage Intacct has Close Assistant. Business Central has Copilot close help. Light runs reconciliation with agents and finance reviews the result.

Then the group. For a multi-entity company this is where the hours hide. On a batch ledger, consolidation is a monthly build. Light treats multi-entity and multi-book as the core, so the group view is current rather than reconstructed.

Then revenue. Native revenue recognition matters if you bill on subscriptions or contracts. In Light it is natively included. On other stacks, check whether it is part of the core licence or a separate line.

Then payment. Light has native bill pay from the company's own bank across more than eighty countries. That keeps payment and ledger in one place instead of a separate rail to reconcile.

Finally, re-measure the same four numbers after a full quarter with a real month end. That is the only honest report on a finance transformation.

NetSuite wins when finance sits inside operations and commerce, and one suite matters more than the shape of the AI.

Business Central wins in a Microsoft estate with inventory or manufacturing, where Copilot and supervised agents are a bonus on a platform you were choosing anyway.

Sage Intacct wins for US-centric finance teams with heavy audit and CPA expectations and a preference for a familiar, partner-supported platform.

Light wins for finance-led buyers with two or more legal entities and no inventory need, who want agents running the work rather than drafting it. Light is cloud-only in AWS EU, from $35,000 per year, and typically fits 30 to 5,000 employees. Named customers include Tillo, KeyShot, and Alva Labs.

Which steps run without a person, and which steps require one? Ask for the list, not the adjective.

Is the ledger live or batch, and what does the group view look like on day nine of the month?

Is revenue recognition part of the core, and what happens with two books and two entities?

What is generally available today, what is in preview, and which regions or languages are supported now rather than planned?
