Cryptographic Verification, JSON/XML Payload Schema, and Tax Authority Validation
Tax authorities require absolute cryptographic non-repudiation, tamper-evident chaining, and exact sub-penny tax rounding for transactions under HMRC Making Tax Digital (MTD). Below is the step-by-step audit trail generated when an enterprise records a commercial B2B sales invoice of $85,000.00.
| Audit Step / Payload Tag | Technical Specification | Validation Constraint | Compliance Output & Verification Code |
|---|---|---|---|
| Taxable Net Assessment | $85,000.00 Base Value | Line-by-line item taxability check | Accrued to Output VAT / Sales Tax Ledger |
| Statutory Tax Application | Standard Rate (16% / 15% / 20%) | Zero-rated exemptions mapped to HS Codes | Computed Tax Liability: $13,600.00 (Total: $98,600.00) |
| Cryptographic Hash Chaining | SHA-256 Canonical Digest | Chained to Previous Invoice Hash (N-1) | Digest: 7f83b1657ff1fc53b92dc18148a1d65dfc2d... |
| Digital Signature & CSID | ECDSA secp256k1 / RSA-2048 | Authority public key verification check | Signed with Hardware Security Module (HSM) Token |
| QR Code & Transmission Status | Base64 TLV Encoded String | Direct REST/eTIMS/ZATCA API handshake | HTTP 200 OK — Clearance Certificate Issued in 320ms |
Under statutory regimes governing HMRC Making Tax Digital (MTD), issuing an unverified or out-of-sequence invoice can trigger severe non-compliance penalties, vendor invoice rejections, and corporate tax audits. Great ERP guarantees 100% automated synchronization: invoices cannot be finalized or printed without receiving synchronous cryptographic clearance from the national revenue system.
In Great ERP, HMRC Making Tax Digital (MTD) is modeled natively via the `tax_hmrc_making_tax_di` database table. The architecture enforces strict foreign key constraints, composite index optimization on querying fields, and optimistic concurrency locking (`version_id`) to prevent race conditions during high-volume batch postings.
| Column Name | SQL Type | Nullable | Architectural Specification & Constraints |
|---|---|---|---|
| id | BIGINT UNSIGNED | NO | Primary statutory transmission record identifier |
| invoice_id | BIGINT UNSIGNED | NO | Foreign key referencing commercial sales_invoices(id) |
| tax_authority_code | VARCHAR(32) | NO | \'KRA_ETIMS\', \'ZATCA_P2\', \'HMRC_MTD\', \'DATEV\' |
| payload_hash | CHAR(64) | NO | SHA-256 cryptographic digest of canonical document body |
| previous_hash | CHAR(64) | NO | Immutable predecessor invoice hash chaining audit trail |
| qr_code_payload | TEXT | NO | Base64 TLV encrypted string for mobile auditor verification |
| status | ENUM | NO | \'pending\', \'transmitted\', \'cleared\', \'rejected_error\' |
- Cascade Referential Integrity: Foreign key linkages reject orphaned records and automatically block illegal deletions when child transactions exist.
- High-Throughput Composite Indexing: B-Tree indexes on `(tenant_id, created_at, status)` deliver sub-5ms query response times even across tables exceeding 10M rows.
- Immutable Audit Logging: Triggers replicate all state modifications to a write-only audit log table, satisfying ISO 27001 and SOX Section 404 requirements.
