Why it is better together
The e-signature is not a separate product with its own login and its own export step. It lives inside the same DonForge file as your designs, documents, photos, PDFs and signature requests. A contractor can write an estimate, design a matching flyer, add before-and-after photos and send the estimate for signature — all from one file that the client sees through one link.
That matters because small businesses lose time and money moving files between apps. Every export and re-upload is a chance for the wrong version to go out. With DonForge, the latest version is always the one in the file, autosaved and versioned, so you can restore any earlier draft.
How to get started
- Choose a document from the file or upload a PDF.
- Add signers and set the order.
- Drop fields onto the pages.
- Send — and get the signed PDF automatically.
Who uses the e-signature
