ZTABS builds e-commerce platforms for Houston companies across B2B industrial supply, energy equipment procurement, medical supply and D2C. We have an office in Houston, Texas and are remote-first by design. Collaboration schedules are agreed per engagement.
Houston is a major B2B e-commerce hub for the American energy industry. The city's energy companies, the Texas Medical Center and the Port of Houston create industrial and enterprise e-commerce demand at a scale that consumer-focused markets rarely approach. The digitisation of energy industry procurement represents significant B2B e-commerce demand. Our broader e-commerce capabilities are on the e-commerce development services page.
Houston e-commerce requires industrial B2B architecture (parametric search, customer-specific pricing, ERP integration), hazmat and compliance logistics, Texas sales tax with manufacturing exemptions, TDPSA data privacy and the scale-ready infrastructure that Houston enterprises demand.
| Sector | What we build | Key requirement |
|---|---|---|
| Energy/industrial supply | Equipment portals, parts catalogs, MRO | SAP, parametric search |
| Medical supply | Device commerce, consumables, lab supply | FDA, UDI tracking |
| Chemical/materials | Bulk ordering, SDS management | Hazmat, TSCA |
| D2C consumer | Storefronts for Houston's large metro | Texas sales tax, TDPSA |
Houston's B2B customers need commerce far beyond consumer storefronts. We build parametric technical search (find a valve by pressure rating, material, size, connection type and ANSI class), customer-specific pricing (contract pricing, volume tiers and blanket purchase orders pulled from SAP or Oracle in real time), quote and approval workflows (B2B purchases often require internal approvals with quote generation, approval routing and PO-based ordering) and ERP integration (SAP, Oracle and industry-specific ERPs with bidirectional sync for pricing, inventory, orders and customer data).
Punchout catalogs enable Houston enterprises to purchase from within their procurement systems (SAP Ariba, Coupa, Oracle) using cXML/OCI protocols, subject to licensed interface access and customer-partner authority. EDI integration (850 for POs, 810 for invoices, 856 for advance shipping notices) serves large enterprise customers with established electronic document exchange agreements.
The energy industry drives massive e-commerce demand for oilfield equipment and parts (drill bits, valves, pumps, sensors and safety equipment with technical specifications and compatibility checking), MRO supplies (maintenance, repair and operations consumables, PPE, tools and facility supplies for refineries and platforms), industrial instruments (pressure gauges, flow meters, analyzers and control equipment requiring configuration verification) and safety equipment (PPE, gas detection, fire suppression with OSHA compliance documentation included with purchases).
Houston commerce frequently involves regulated materials. We implement hazmat documentation support (displaying DOT hazmat classes, UN numbers and proper shipping names on product pages from authoritative classification data; actual shipper responsibility for current classification, SDS accuracy, trained staff, package type/quantity/mode and carrier acceptance per HMR remains with the operator), SDS management (Safety Data Sheets linked to chemical products), export controls (EAR and ITAR classification display for energy equipment, with actual jurisdiction/licence/end-use determination per product/destination) and certificate management (material test certificates, calibration certificates and conformity documents linked to specific product lots).
The Texas Medical Center's institutions procure significant volumes of medical equipment, supplies and pharmaceuticals. Medical e-commerce involves UDI (Unique Device Identifier) tracking for applicable device classes (UDI labeler obligations, device classification and exceptions vary by product), lot management, FDA documentation linkage for the specific device/drug market route (510(k), PMA or exempt), cold chain requirements for temperature-sensitive products with actual storage/carrier/packaging conditions, and controlled substance handling for DEA-scheduled materials where the merchant holds appropriate DEA registration. Not all medical products are automatically regulated under the same framework. Laboratory supply commerce needs certificates of analysis linked to specific product lots.
Texas sales tax (6.25% state plus up to 2% local) includes exemptions for items used directly in manufacturing goods for sale by a qualifying taxpayer with a valid exemption certificate. Hand tools, support items, sales/distribution/transport equipment and general office supplies are generally excluded from the manufacturing exemption. Actual nexus, sourcing, product classification and certificate validity determine tax treatment. Tax automation through Avalara or TaxJar assists with rate lookup and exemption certificate management but does not ensure legal compliance. The TDPSA (Texas Data Privacy and Security Act) applies under BC 541.002 to entities conducting business in Texas or targeting Texas residents that process or sell consumer personal data and are not small businesses as defined by the SBA for most provisions. There is no consumer-volume or revenue threshold gate (unlike CCPA). Entity-level exemptions exist for HIPAA-covered entities, financial institutions and others. Small businesses have distinct consent requirements specifically for the sale of sensitive personal data, not blanket exemption from all processing obligations.
Houston enterprise B2B processes high volumes. We build high-volume catalog management (designed for catalogs exceeding 100,000 SKUs with complex technical attributes and PIM integration; actual performance depends on agreed payload and configuration targets), multi-warehouse inventory (Houston warehouse, Permian Basin depot, Gulf Coast port facility with inventory visibility across locations and shipping optimisation routing orders to the nearest warehouse with stock), bulk ordering (cart systems designed for large orders with rapid-add by part number; actual line-item capacity depends on agreed payload and testing targets), EDI integration for enterprise customers (EDI 850 purchase orders, EDI 855 acknowledgments, EDI 856 advance ship notices and EDI 810 invoices) and barcode scanning for warehouse pick, pack and ship workflows.
Houston's large metro population creates substantial D2C demand across Hispanic food and lifestyle (Houston's extraordinarily diverse population drives specialty food, beauty and cultural product D2C), BBQ and food culture (sauces, rubs, smoked meats, cooking accessories and smoking equipment with subscription options for regular delivery), outdoor and marine (Gulf Coast recreation, fishing, boating and outdoor gear with seasonal merchandising for fishing seasons and hurricane preparedness) and energy transition consumer products (solar panels, EV chargers and home energy products with compatibility checking and installation booking).
Houston industrial and consumer commerce benefits from subscription models. Industrial consumable subscriptions (regular delivery of filters, lubricants, safety supplies and maintenance materials at scheduled intervals), MRO replenishment (automatic reorder when inventory drops below threshold for maintenance, repair and operations supplies), consumer D2C subscriptions (BBQ supplies, coffee, specialty food with flexible management) and lab consumable subscriptions for TMC institutions (reagents, disposables and standard supplies on recurring schedules).
Port Houston's public terminals rank among the top US ports by waterborne tonnage (the broader Houston Ship Channel complex, combining public and private facilities, handles massive volumes). This creates import/export commerce. We integrate with customs documentation systems, build landed cost calculators (showing total cost including duties, shipping and insurance at checkout), support multi-currency transactions for international buyers and connect with freight forwarders for oversized industrial shipments.
Shopify Plus works for D2C storefronts and mid-complexity B2B with Shopify's B2B features. Headless Next.js with Shopify backend provides maximum design control and performance for brands needing custom product experiences. Custom platforms serve complex B2B with deep ERP integration, punchout catalogs and EDI requirements. Platform selection depends on catalog complexity, integration requirements and customer purchasing patterns.
A Houston industrial supply company serving Gulf Coast energy customers would build a B2B portal with parametric technical search (engineers find valves by pressure rating, material, size and ANSI class), customer-specific pricing from SAP (contract prices displayed when authenticated customers browse), real-time multi-warehouse inventory (Houston main, Corpus Christi depot, Midland depot with shipping optimisation) and punchout catalogs for enterprise procurement systems.
SAP bidirectional integration. Texas sales tax with qualifying manufacturing exemptions (actual qualifying use, valid exemption certificate and Comptroller guidance per product class required). EDI for enterprise customers.
Development scope depends on catalog size, ERP complexity and customer account structure. A Shopify/template store for simpler B2B ($5K to $25K from our e-commerce cost guide) would handle basic catalog commerce. Custom WooCommerce/Shopify with ERP integration ($25K to $60K) would support mid-complexity B2B. Headless commerce with SAP and punchout ($60K to $120K) would serve enterprise (punchout and EDI are separately scoped additions agreed per engagement). Custom platform with EDI and multi-warehouse ($120K to $200K+) would handle the most complex industrial requirements. Actual scope and timeline are agreed per engagement.
This is a hypothetical scenario for illustration. Actual scope, timeline and cost depend on your requirements.
Houston e-commerce integrates with SAP, Oracle, Epicor and industry-specific ERPs, payment processors (Stripe, PayPal, Net-30/60 terms for B2B), shipping carriers (FedEx, UPS, specialized hazmat carriers), tax automation (Avalara, TaxJar) and Houston's logistics infrastructure (Port of Houston for import/export, rail connections for bulk shipment).
B2B checkout handles PO-based ordering, credit terms (Net 30/60 for established accounts with credit limit management), credit card payment and approval routing for purchases above threshold amounts. D2C checkout supports standard payment methods (credit card, Apple Pay, Google Pay, Shop Pay) with Texas sales tax correctly calculated including qualifying manufacturing exemptions where valid exemption certificates are on file. Guest checkout for D2C, account-based checkout for B2B. Buy Now Pay Later (Afterpay, Klarna, Affirm) for consumer purchases. Multi-currency for international energy industry buyers.
Houston industrial e-commerce often requires custom quoting rather than fixed pricing. We build request-for-quote submission (customers specify quantity, specifications, delivery requirements and receive formal quotes), quote management dashboards (sales teams track open quotes, follow up on pending quotes and convert accepted quotes to orders), volume-based pricing calculators (automated pricing based on quantity breaks, contract terms and customer tier) and negotiated pricing (account-specific prices that override catalog pricing for established customers).
Houston industrial catalogs often exceed 100,000 SKUs with complex technical attributes. Product Information Management (PIM) systems (Salsify, Akeneo, inRiver) manage product data across channels. Search architecture uses faceted navigation with technical specifications, cross-reference capability (competitor part number lookup), compatibility checking (displaying manufacturer-provided compatibility data; actual physical fit depends on manufacturer specifications, product configuration, condition and proper installation) and natural language search (engineers searching "3-inch stainless steel gate valve 150 PSI" should find the right product). Catalog data enrichment includes technical drawings, CAD files, installation manuals and safety data sheets.
Houston's industrial and energy commerce frequently involves hazardous materials. We build hazmat documentation support (identifying products flagged for DOT, IATA or IMO special handling based on classification data), carrier selection (routing hazmat shipments to carriers accepting the specific class/quantity/mode), documentation automation (generating shipping paperwork templates including hazmat declarations) and packaging guidance display (showing applicable container and labelling requirements). Actual physical compliance with DOT/IATA/IMDG packaging, labelling and trained-shipper requirements is the operator's responsibility.
Houston has a strong logistics position for heavy and oversized goods. The Port of Houston complex handles massive tonnage annually, the city has major railroad connections, and the interstate system connects Houston to every Gulf Coast and Texas market. E-commerce shipping from Houston reaches most of the Southern US population quickly by ground. Hazmat shipping requires proper DOT classification, packaging, labeling and documentation integrated into the checkout flow.
Production e-commerce needs monitoring including SAP sync health, inventory accuracy across warehouses, payment processing, tax calculation correctness and shipping integration status. B2B portals need order processing pipeline monitoring with alerting for failed ERP syncs or pricing discrepancies.
Houston enterprises migrating from phone/email/fax ordering need structured product data migration (technical specifications, pricing matrices, customer accounts), ERP integration testing and parallel running before cutover. Product photography and technical drawing digitisation for catalogs transitioning from paper to digital.
Collaboration schedules are agreed per engagement. Illustrative phase sequence:
Our usual stack is Next.js for headless frontends, Node.js with PostgreSQL for custom backends and B2B order management, Shopify Plus for hosted commerce and D2C channels, and AWS for infrastructure with multi-region capability. We also offer AI development services for product recommendations, search intelligence and demand forecasting. Web development supports marketing sites alongside the commerce platform.
Costs depend on platform choice, catalog complexity and integration scope. These ranges come from our e-commerce cost guide. All costs are in USD.
| Build | Typical cost | Typical timeline |
|---|---|---|
| Shopify/template store (basic catalog, standard checkout) | $5K to $25K | 2 to 6 weeks |
| Custom WooCommerce/Shopify (advanced filtering, multi-currency) | $25K to $60K | 6 to 14 weeks |
| Headless commerce (Next.js + Shopify, custom UI, performance) | $60K to $120K | 14 to 24 weeks |
| Custom e-commerce platform (marketplace, multi-vendor, B2B) | $120K to $200K+ | 24 to 40 weeks |
B2B industrial with SAP integration adds ERP connectivity complexity. Medical supply adds FDA compliance. Hazmat shipping adds compliance documentation. These are planning benchmarks from the published guide, not guaranteed turnarounds. Scope and timelines are defined during discovery and agreed per engagement.
After launch, Houston e-commerce needs SAP sync monitoring, inventory accuracy maintenance, tax rate updates (Texas rates change periodically), product data management and seasonal merchandising. Ongoing development budgets are illustrative at $3,000 to $15,000 per month and scoped per engagement based on complexity. Industrial B2B tends toward the higher end due to ERP sync monitoring, product data management and tax compliance updates.
