PandaDoc
Best for client proposals and contracts
Agencies live in proposals, statements of work and contracts, and PandaDoc handles all three in one branded flow with the signature built in. Templates and a content library cut the time on every new client, and the CRM links keep the pipeline honest. You pay per seat for that breadth, so it suits agencies that send a lot.
When the deliverable just needs a clean, fast signature, Dropbox Sign keeps the client experience simple and on brand. Unlimited requests suit agencies juggling many accounts. It does not build the proposal for you, which is the gap against PandaDoc.
For high value retainers and contracts, the DocuSign name reassures clients and their legal teams. Bulk send helps when the same agreement goes to many. Envelope limits and extra fees are the watch items as volume climbs.
If the agency sends a high volume of routine documents, SignWell keeps the cost flat with unlimited paid sends and tidy branding. The reporting and integrations are lighter, which larger agencies may eventually outgrow.
For a small studio that wants signing handled without ceremony, Signaturely is quick to brand and quick to send. It will not anchor a full proposal workflow, but it covers the basics cleanly and cheaply.
