v0.1.9 (experimental)
An implementation of Saudi Arabia ZATCA's E-Invoicing requirements, processes, and standards in TypeScript.
Check out Invoicen
If you plan on using the built in EGS
module to generate keys, and CSR. The EGS
module in the package is dependent on OpenSSL being installed in the system it's running on. It's being used to generate an ECDSA
key pair using the secp256k1
curve. also to generate and sign a CSR.
All other parts of the package will work fine without OpenSSL
. (meaning it supports react-native and other frameworks)
All tha main futures required to on-board a new EGS. Create, sign, and report a simplified tax invoice are currently supported.
- EGS (E-Invoice Generation System).
- Creation/on-boarding (Compliance and Production x.509 CSIDs).
- Cryptographic stamps generation.
- Simplified Tax Invoice.
- Creation.
- Signing.
- Compliance checking.
- Reporting.

import {
EGS, EGSUnitInfo,
ZATCASimplifiedTaxInvoice,
} from "zatca-xml-js";
// New Invoice and EGS Unit
const invoice: ZATCASimplifiedTaxInvoice = {/*...*/};
const egsunit: EGSUnitInfo = {/*...*/};
// Init EGS unit
const egs = new EGS(egsunit);
// New Keys & CSR for the EGS
await egs.generateNewKeysAndCSR(false, "solution_name");
// Issue a new compliance cert for the EGS
const compliance_rid = await egs.issueComplianceCertificate("123345");
// Sign invoice
const {signed_invoice_string, invoice_hash} = egs.signInvoice(invoice);
// Check invoice compliance
await egs.checkInvoiceCompliance(signed_invoice_string, invoice_hash);
// Issue production certificate
await egs.issueProductionCertificate(compliance_rid);
// Report invoice
await egs.reportInvoice(signed_invoice_string, invoice_hash);

All contributions are appreciated.
- CSIDs renewal, revoking.
- Populating templates using a template engine instead of
replace
- Getting ZATCA to hopefully minify the XMLs before hashing ?
I'm not planning on supporting Tax Invoices
(Not simplified ones). If any one wants to tackle that part.
