E-signature integrations
A signature proves someone signed. It does not prove who they are.
Signing sits right next to identity collection at the front of the client lifecycle, which is why the two are so often confused. A firm that has just verified a client should not then chase a signature through a separate email thread — the engagement letter and the compliance record belong to the same moment.
StackGo runs the identity and AML work; your signing tool does what it is good at. The result is one file with both, instead of two systems and a gap between them.

What to look for in a signing tool if you are regulated
Be clear about what it is not. An e-signature is evidence of assent, not evidence of identity. Treating a signed engagement letter as a KYC control is a common and expensive misunderstanding.
Data residency. For AU firms with residency obligations, where the signed document is stored matters as much as how it was signed. Australian-hosted signing exists and is worth choosing deliberately.
Audit trail depth. Timestamp, IP, and a tamper-evident record are the minimum. If a signature cannot be defended later it is decoration.
Retention. Your compliance file has a seven-year life. Make sure your signing provider’s retention policy is at least as long, or you will be reconstructing evidence you thought you had.
