XERO

 It's one of the world's most popular cloud-based accounting platforms for small and medium-sized businesses. It was founded in New Zealand and is widely used by tradespeople, builders, retailers, consultants, and service businesses. 

Some of Xero's key features include:

• Invoicing and quotes – Create professional invoices, send quotes, and track when customers pay.

• Bank reconciliation – Connect your bank accounts so transactions are imported automatically and matched to your records.

• Bills and expenses – Record supplier bills, track expenses, and manage payments.

• GST and tax – Prepare GST returns and keep tax records organized for New Zealand businesses.

• Payroll – Available in some regions, including New Zealand, to manage employee pay and leave.

• Financial reporting – Generate profit and loss statements, balance sheets, cash flow reports, and other financial reports.

• Mobile app – Send invoices, approve bills, reconcile bank transactions, and monitor your business while away from your desk. 

For a residential building company, Rave Build and Xero complement each other rather than compete:

• Rave Build manages your projects, estimating, scheduling, purchase orders, and job costing.

• Xero manages your accounting, banking, invoicing, payroll (where applicable), GST, and financial reporting.

Many building companies integrate Rave Build with Xero so project costs and invoices flow into the accounting system automatically, reducing duplicate data entry.

Cambridge Homes uses this combination because it separates operational project management from financial accounting while allowing the two systems to work together.
