Build it
Your columns, your sections, your markup.
Set a standard markup for the studio, then adjust individual lines when needed. Add your own columns and they behave like the ones built in — sorted, filtered, pinned, and on the client document if you want them there.
Your own columns
Lead timeFinishFabricInstaller
Installer is on the client document as well.
Markup
20.00% is the studio’s standard, set once in settings.
Line 01.5 carries its own rate of 15.00%.
Issue it
The same line, told two ways.
Ten documents are issued from one schedule — the client estimate, the contractor specification, the supplier enquiry, the purchase order. You decide what each reader may see, and the decision holds: a forgotten column cannot put your trade price in front of a client.
All from the same lines

The client estimate sets out the proposed costs. The client schedule presents the specification, section by section.
Every issue is kept, so there is always a record of what you sent and when.

Reconcile it
What you specified against what you were invoiced.
Orders, deliveries and supplier invoices land back on the lines they came from. When a figure moves, the variance is on the line that moved, not buried in a month-end total — and it reaches Xero already reconciled.

Happy with the estimate. Please go ahead.
Let’s hold this estimate for now.
Could we see a warmer finish for the wall lights?
