Business Identity & Vault Manager — what it does
Holds the business details you retype on every filing — company profile, GSTIN with checksum validation, client and vendor roster, HSN catalog — in one encrypted store on your own device. The point is that the master data that appears on every invoice lives in one place with one source of truth.
How to use Business Identity & Vault Manager
- Add your company profile: name, address, GSTIN, state code and contact details.
- Run the GSTIN checksum check so a typo is caught now rather than rejected later at an e-invoice upload.
- Build the client and vendor roster with each party's GSTIN, state code and default payment terms.
- Add the HSN/SAC codes you bill most often, with their rates and short descriptions.
- Use the stored records to fill invoices, e-invoice JSON and reconciliation runs instead of retyping them.
Worked example: one GSTIN typo, many rejected files
A vendor GSTIN with a transposed digit gets reused across a quarter of purchase entries, and every e-invoice upload referencing it fails with a check-digit error. Storing the verified GSTIN once means the error exists in one record, and finding it takes seconds instead of an afternoon.

Frequently asked questions
- What is Business Identity & Vault Manager?
- Manage your company profile, GSTIN checksum, client/vendor roster and HSN catalog in an encrypted on-device single source of truth.
- Is Business Identity & Vault Manager free to use?
- Yes — Business Identity & Vault Manager is free to use, with no sign-up, no install and no account.
- Does Business Identity & Vault Manager upload or store my data?
- No — Business Identity & Vault Manager runs entirely in your browser, so your text, files and results never leave your device.
- Do I need to install anything to use Business Identity & Vault Manager?
- No — it works in any modern browser (Chrome, Edge, Firefox, Safari) with no downloads, accounts or plugins.
- What happens to the vault if I clear browser data?
- It is stored in this browser, so clearing site data removes it. Export a backup before clearing anything, and treat the vault as one device's master copy rather than a synced record.
- Is it safe to keep client GSTINs here?
- The records stay on your device and are never transmitted, which is a better position than a client identifier pasted into an online form. Still treat the device itself as the boundary — anyone who can open your browser profile can open the vault.
