How to Create a Professional Invoice
ZenBuild's PDF Creator includes a pre-built Invoice template with your business details, client information, line items, and automatic calculations. Fill in the fields and download a professional PDF in seconds.
Step-by-step guide
Open the Invoice template
Navigate to the PDF Creator and select the Invoice template from the template gallery. The template comes pre-designed with a professional layout including your business details, client information, line items table, totals, and payment terms.
Fill in your details
On the left panel, fill in the variable fields: your business name, address, and contact info, client details, invoice number and date, line items with descriptions, quantities, and prices, and payment terms. The right panel shows a live preview that updates as you type. Line item totals and the grand total calculate automatically.
Download your invoice
Click Download PDF to export your invoice. The template renders a clean, print-ready PDF with all your details formatted professionally. Save the template to your account to reuse it — next time you only need to update the client info and line items.

Frequently asked questions
Can I customize the invoice template design?
Yes. Open the template in the canvas editor to modify the layout, fonts, colors, and add your logo. Save your customized version as a new template for future use.
Can I generate invoices automatically?
Yes. ZenBuild's REST API includes a PDF create endpoint that accepts a template ID and variable values. Integrate it with your billing system to generate invoices programmatically.
Do invoice totals calculate automatically?
Yes. The template uses computed variables — line item subtotals, tax, and grand total update automatically based on the quantities and prices you enter.
