Subprocessors
Last updated: 2026-06-27
To deliver the Quittance Service we use the third-party sub-processors below. Each is bound by contract to data-protection obligations consistent with our DPA. This list is provided for transparency under the GDPR.
| Sub-processor | Purpose | Data hosting region |
|---|---|---|
| Vercel | Application hosting & CDN | United States |
| Clerk | Authentication & user management | United States |
| Resend | Transactional & notification email | United States |
| Anthropic | AI document understanding & reconciliation (commercial API; does not train on customer data) | United States |
| Neon | Managed Postgres database (structured customer content) | United States (us-east-1) |
| Vercel Blob | Document & file storage (uploaded invoices & agreements) | United States |
| Google (Fonts) | Global CDN web-font delivery on the website | Global CDN |
Note: systems you connect to Quittance (for example your Docusign Agreement Manager repository and your accounting system) are your own services and data sources, not Quittance sub-processors.
Changes
We will update this page before adding or replacing a sub-processor and, per the DPA, give customers advance notice and an opportunity to object. To be notified of changes to this list, contact privacy@quittance.ai.
