Estimates & Quotations

Send professional quotes to clients before starting work. Estimates use the same line-item structure as invoices but are clearly marked as non-binding quotations.

Creating an Estimate

Navigate to Estimates → Create Estimate. The form works just like invoices — add a client, line items, taxes, and notes. Save as draft, download as PDF, or email to your client.

Items

Build a catalog of your services and products. Save items with descriptions and rates so you can add them to invoices with a single click.

Recurring Invoices

Automate your billing with recurring invoices. Set up a schedule and InvoiceBlitz will automatically generate and send invoices at your chosen interval.

Note: Recurring invoices require the Starter ($5/mo) or Pro ($10/mo) plan.

Setting Up a Schedule

Go to Recurring from the sidebar. Create a new schedule by selecting a client, adding line items, and choosing the frequency — weekly, monthly, quarterly, or yearly.
