How a freelance professional handled 189 proposals in 40 minutes
An accounting practice in Dublin found that 189 proposals from the previous quarter contained an inconsistency flagged by Sellsy, HubSpot, Salesforce CPQ, PandaDoc, Better Proposals; SAM.gov for federal..

The whole job took under 40 minutes per file, and the corrected files were re-shared via secure email the same day. Every proposal kept its original layout, signatures, and embedded metadata.

Step-by-step: signing a proposal PDF without breaking the layout
- Save the original as a safety copy

- Verify dependent fields
For totals, references, or cross-linked figures, scroll through the document and check that nothing else needs updating. EasyPDF does not auto-recalculate.

Frequently Asked Questions
Can I update pricing in a PDF proposal?
Yes, EasyPDF lets you edit any text in your proposal PDF, including pricing tables and figures.
Will the recipient know I edited the proposal?
A standard PDF reader does not show an edit history by default. However, the file's metadata can include modification timestamps. For full transparency on material changes, attach a short note explaining the correction when you send the updated proposal.
Can I add a watermark before sharing the proposal?
Yes, EasyPDF has a free watermark tool. A "DRAFT" or "COPY" overlay is useful when sharing a corrected proposal for review before the final version goes out.
How do I redact sensitive fields on a proposal before sharing?
Use the redaction tool (not just black text on top). Select the area, choose "Black out and remove text", then save with the "flatten" option. This removes the underlying data permanently so advanced PDF readers cannot recover it.
What does the upload threshold benchmark mean for my proposal?
According to industry sources, 25 MB is the upload threshold. Keep this in mind when preparing or sharing your proposal, since exceeding this threshold typically triggers a rejection or a manual review at Sellsy, HubSpot, Salesforce CPQ, PandaDoc, Better Proposals; SAM.gov for federal..
Is it legal to sign a proposal PDF?

Always keep the original as evidence.
Will signing my proposal affect its legal validity?
A PDF that has not been digitally signed remains valid after editing, since validity rests on substance, not file format. Once a proposal has been digitally signed, any edit invalidates the signature. For signed documents, issue a corrected version with a fresh signature instead.
How do I sign a proposal PDF scanned from paper?
Run OCR first so the text becomes selectable. EasyPDF detects scanned PDFs and offers OCR in a single click. Proofread the OCR result on small fonts, since digit recognition errors are common on dense proposals.
Can I sign a proposal that is password-protected?
You need the original password to unlock the PDF first. Once unlocked, edits work like any other PDF. EasyPDF can re-apply a password on save if you want to keep the file protected.
How do I keep an audit log of the changes I made to a proposal?
The simplest approach is to save each version with a timestamped filename (e.g. proposal-2026-04-INIT.pdf, proposal-2026-04-CORR.pdf). For regulated industries, store every version in your document management system as required by ESIGN-signed proposals become contracts upon countersignature in B2B; UCC governs goods..
Is it safe to sign a proposal with sensitive data online?
EasyPDF processes files in your browser by default, so the proposal content does not leave your machine. Check the privacy indicator in the editor toolbar to confirm browser-side mode is active before opening sensitive documents.
