Invoicing a job in stages
On a bigger job, each stage gets its own tax invoice: the deposit, each progress payment and the final balance. Name the stage on the invoice, such as "Stage 2 of 3: retaining walls complete", and reference the accepted quote. The final invoice should show the full job and take off everything already paid, listing those invoices by number.
Materials, hire and tip fees
Show soil, turf, plants and other materials by quantity, the same way you quoted them. Machine hire and tip fees go on their own lines. If you pass on a cost with a markup, the whole line is your price to the customer; GST applies to it like any other taxable line when you are registered. In Karya Falak, billable expenses recorded against a job can be added to the invoice at cost plus your markup.
Maintenance rounds
Garden maintenance clients are usually easiest to invoice once a month, listing each visit by date. Note any extras, such as hedging or a load of mulch, with the visit they were done on.
Staged invoices without the spreadsheet
In Karya Falak the invoice for the accepted quote takes the deposit off automatically, though stage invoices you raise in between aren’t taken off for you. The profit on each job shows in job costing, and maintenance visits can be invoiced monthly. Invoices and payments go to Xero or QuickBooks.
