**Built for invoices.** Whether it's invoices, contracts, receipts, Arthize's fill pdf form keeps the work inside your private workspace. A small business's financial and client documents are confidential and shouldn't be retained by a free ad-funded tool.

## What matters when you fill out a PDF form

Completed forms can be flattened so values are locked.

No printing or scanning is required.
