Consolidation, not a spreadsheet export
Most "consolidation" in small-business software is a folder of separate company files and a manual spreadsheet that stitches them together at year-end. It breaks the first time an intercompany invoice, a minority shareholder, or a foreign subsidiary enters the picture — which is to say, immediately for any real group.
HelloBooks consolidates the way an audit expects. Each member company keeps its own books; the group layer reads them live, converts to your presentation currency, removes the transactions companies did with each other, attributes the outside owners their share, and produces eight consolidated statements you can drill from the group total all the way down to a single member’s journal line.
