B2B Software Consulting in San Jose
San Jose runs on hardware, so the ERP question is BOM depth, engineering change orders and export classification, not another CRM. ERPStack stays remote-first: PostgreSQL and Next.js on AWS us-west-1 (N. California), where newer accounts reach only two of the three Availability Zones.
Quick Answer
In short: a San Jose hardware ERP is a part-master problem: multi-level BOM under engineering-change-order control, RoHS and conflict-minerals joins on the part record, and ECCN 3A090 export screening before a shipment leaves. ERPStack builds it on PostgreSQL in AWS us-west-1, three Availability Zones, with CMMC-aware controls under DFARS Subpart 204.75.
Regional Compliance
- RoHS Directive 2011/65/EU (ten restricted substances)
- Conflict minerals: Form SD under 17 CFR 240.13p-1
- EAR advanced computing controls (15 CFR 742.6, ECCN 3A090)
- CMMC under DFARS Subpart 204.75 (Levels 1, 2, 3)
- R&TC § 441 business property statement (due 1 April)
Security & Compliance Architecture
CCPA, CPRA and the CPPA’s ADMT rules are the California floor for San Jose as well. What actually shapes a San Jose ERP is export control, defense flow-down and tax geography.
Export control reaches design data
15 CFR 742.6 licenses advanced computing ECCNs 3A090 and 4A090 to Macau and Country Group D:5 under a presumption of denial, and 15 CFR 734.13(b) makes showing that data to a foreign person in San Jose a deemed export. RBAC carries the rule into the PostgreSQL schema.CMMC for defense-adjacent hardware
DFARS Subpart 204.75 recognises Level 1 (Self), Level 2 (Self or C3PAO) and Level 3 (DIBCAC), with a Final Level 2 assessment no older than 3 years and yearly affirmation; primes send SOC 2 and ISO 27001 questionnaires alongside. ERPStack holds no CMMC certification, and builds ERP that produces assessor-ready evidence.R&D is now split by geography
26 U.S.C. § 174A deducts domestic research immediately for taxable years beginning after 31 December 2024, while foreign research stays amortised under § 174. A San Jose ERP tags every timesheet and cost centre with the country the work happened in.The county wants your fixed-asset register
Revenue and Taxation Code § 441 requires an annual property statement from a San Jose business holding $100,000 or more of taxable personal property, by 5 p.m. on 1 April with a penalty after 7 May — cost by acquisition year, from the PostgreSQL asset register.
Engineering Blueprint
San Jose is where the hardware lives: manufacturing here is BOM depth and change control, not pipeline stages. A San Jose bill of materials is a graph with effectivity dates, every row carrying a compliance attribute.
Multi-level BOM under ECO control
Bill of Materials (BOM) Management for San Jose hardware means recursive parent-child rows in PostgreSQL, dated by engineering change order, an AVL/AML per part, and PLM revisions arriving through an idempotent TypeScript API. Every ECO approval lands in an Immutable Audit Trail.
// Drizzle ORM — BOM line with ECO effectivity and RoHS state
export const bomLine = pgTable('bom_line', {
parentPart: varchar('parent_part', { length: 32 }).notNull(),
childPart: varchar('child_part', { length: 32 }).notNull(),
ecoIn: varchar('eco_in', { length: 16 }).notNull(),
rohsStatus: varchar('rohs_status', { length: 16 }).notNull(),
});Compliance is a join on the part master
RoHS Directive 2011/65/EU restricts ten substances, including four phthalates added by (EU) 2015/863, and Form SD reporting under 17 CFR 240.13p-1 covers conflict minerals necessary to a product’s functionality. For a San Jose ERP those are part-master columns rolled up the BOM in PostgreSQL, field returns scored in a ClickHouse Analytics Database.
Where a San Jose workload actually sits
AWS us-west-1 (N. California) is nearest to San Jose, but newer accounts reach only two of its three Availability Zones, so quorum-sensitive PostgreSQL and Redis plan around us-west-2 and its four — one Terraform variable. Santa Clara’s city-owned Silicon Valley Power runs a 587.8 MW peak with Intel, Applied Materials and NVIDIA on its grid, next door.

Frequently Asked Questions
At one or two products and a single contract manufacturer, Odoo or Epicor is the right call — do not build. Build custom when ECO effectivity, AVL/AML, RMA failure analysis and export classification collide, because that is where packaged ERP pushes a San Jose manufacturing team into spreadsheets.
A San Francisco SaaS build is Next.js, seats and subscriptions; San Jose hardware ships from a BOM. The San Jose ERP is dominated by revision effectivity, contract manufacturers, component shortage and RMA history, so the PostgreSQL schema centres on parts, lots and engineering change orders.
As part attributes, not attachments. RoHS Directive 2011/65/EU restricts ten substances, including four phthalates added by (EU) 2015/863, and Form SD under 17 CFR 240.13p-1 covers conflict minerals necessary to a product’s functionality. A San Jose ERP holds both on the part master and rolls them up the BOM in PostgreSQL.
It makes citizenship an access control. 15 CFR 734.13(b) treats releasing technology to a foreign person in San Jose as an export to their country of citizenship, and 15 CFR 742.6 licenses advanced computing ECCNs 3A090 and 4A090 to Country Group D:5 under a presumption of denial.
It depends on the contract. DFARS Subpart 204.75 defines Level 1 (Self), Level 2 (Self or C3PAO) and Level 3 (DIBCAC), with a Final Level 2 assessment no older than three years plus annual affirmation. ERPStack is not CMMC-certified; we build San Jose ERP that produces assessor-ready evidence.
By work location, at entry. 26 U.S.C. § 174A deducts domestic research immediately for taxable years beginning after 31 December 2024, while foreign research stays amortised under § 174, so a San Jose ERP tags timesheets, contractor invoices and cost centres with the country of the work.
