Avalara ECM/CertCapture API

Manage sales tax exemptions and documentation in the cloud

Avalara ECM/CertCapture provides automated tax compliance document management. It’s a quick and easy way to handle your exemption certificate process and be prepared for audits, long before they occur.

Make exempt sales easy in any channel

Collect and apply certificates at the point of sale, whether in person, over the phone, or online.

Improve customer experience

Enable customers to upload existing certificates or submit information to generate a new one.

Reduce noncompliance risk

Confirm certificates are valid at the point of collection without expending additional resources.

Simplify billing, even as you grow

Automatically apply exemptions when a valid certificate is on file, reducing credits and rebills.
