Questions

Should I invoice a renovation in stages?

On larger jobs, yes. Bill a deposit before you start, then each stage as it is done. In the Sumocat app, a payment schedule on the estimate turns each stage into its own invoice.

Which taxes does this template use?

The Canada version uses GST 5% and PST 6% for Saskatchewan, in Canadian dollars. The US version uses sales tax 5% for Wisconsin, in US dollars. They are examples: which taxes apply depends on where you work and what you sell, so check with your tax authority.

Is this template free?

Yes. Open it in the free invoice generator, change anything, and download the PDF with no sign up and no watermark. To keep your clients and prices and send each invoice from your iPhone, use the Sumocat app with a free account.
