Signature Custody Split

Signature Custody Split separates two decisions agencies usually bundle: where signed documents live, and which engine captures the signature. Bundling them feels efficient, but it hands one vendor control of both the signing event and the archive, so migrating later means re-papering client history. Splitting custody keeps the signed PDF in storage the agency controls while the signing engine stays replaceable. Dropbox Sign illustrates the bundled path: agreements save automatically into Dropbox storage, convenient until a client asks for a different archive. DocuSeal illustrates the split path, since it can run on-premises with signing embedded into an agency's own application. Xodo Sign sits between them with audit trails and an embedding API but no white-label option. For agencies on retainer, the split matters at renewal: a client leaving should trigger an archive export, not a re-signing project. Audit where executed contracts physically rest before renewing any eSignature contract.
