Frequently Asked Questions

Everything you need to know.

Are electronically signed purchase agreements legally binding?

Yes. Under the ESIGN Act, UETA, and eIDAS, electronic signatures on purchase agreements carry the same legal weight as handwritten signatures, provided both parties consent and the process captures adequate audit evidence.

What purchase agreement types can I sign with Zignature?

Zignature supports asset purchase agreements, product/goods purchase orders, real property purchase agreements, business acquisition agreements, vehicle sale agreements, and service purchase contracts.

Can I require identity verification for high-value purchases?

Yes. Zignature's optional identity verification step requires signers to upload a government ID and take a selfie before signing — creating a strong identity tie to the signature.

How long are signed purchase agreements stored?

Signed documents are stored indefinitely by default. You can configure retention policies to auto-archive or delete after a set period for compliance purposes.

Can purchase agreements be signed on mobile?

Yes. Zignature's signing experience is fully mobile-optimized. Signers can review, annotate, and sign purchase agreements from any smartphone or tablet without installing an app.

Does Zignature integrate with QuickBooks or Xero for purchase orders?

Yes. Zignature connects to QuickBooks and Xero to pull vendor and product data, auto-populate purchase agreements, and trigger invoice creation upon signing.
