Docusign

Docusign's advantage is not the product, it is that a brand's legal team has already approved it. For a creator signing sponsorship agreements that is worth more than a cheaper competitor. The personal plan's five envelopes a month is the constraint to check before subscribing.

Personal is $11 a month on an annual commitment of $132, and is capped at five envelopes a month, which is the limit that catches people out. Standard is $30 a user a month for 100 envelopes a user a year plus templates and branding. Business Pro is $45 and adds payment collection and bulk send. Annual plans are advertised at up to 44 percent off.

A creator signing brand and sponsorship agreements where the other side proposes the tool, and anybody who needs a signature to be unarguable. A freelancer who also wants proposals and invoicing should look at Bonsai, which bundles all three.
