An estimate (also called a quotation or quote) is the pre-work document that precedes an invoice — it sets out the expected cost of a project or service before work begins, giving the client a basis for approval. A professional estimate builds credibility, sets clear expectations, and reduces disputes about scope and pricing later. Freelancers, contractors, and small businesses often struggle to produce professional-looking estimates quickly — resorting to rough emails or Word documents that look unprofessional compared to established agency quotes. The Utility Spark Estimate Generator creates a formatted, professional estimate document in seconds: enter client details, add line items with descriptions and rates, apply taxes or discounts, add payment terms and validity period, and download as a ready-to-share PDF. No account, no server, no data stored.

Professional Template — Client-Ready PDF
The estimate template includes: estimate number, date, validity period, client and business details, itemised line items with descriptions/quantities/rates, subtotal, taxes, discount, and total. The PDF output is clean and professional — suitable for sending to corporate clients who expect formal documentation.
GST Line Item Support
Add GST at applicable rates (5%, 12%, 18%, 28%) as a separate line or as a percentage of the subtotal. The estimate shows pre-GST subtotal and GST amount separately, matching the format expected by business clients.

Set the estimate validity period (e.g. 'valid for 30 days from date'). Add custom terms and conditions, payment terms, and scope notes in a freeform text section.
