- Signature types — Draw, type, or upload signatures?
- WordPress integration — Native plugin or external redirect?
- Pricing model — Per-signature, per-user, or flat fee?
- Data ownership — Self-hosted or cloud-dependent?

Best for: Businesses that need fully compliant, unlimited e-signatures at the lowest cost.

WP E-Signature by ApproveMe has been in the market since 2013, making it one of the earliest WordPress-native e-signature solutions. It offers a solid feature set including document signing, signer invitations, and basic audit trails.
