ZTABS builds production e-commerce platforms for Houston companies — B2B industrial supply portals for the energy corridor, equipment procurement platforms for oilfield services, and D2C storefronts with Texas sales tax compliance and the logistics integration that the Gulf Coast's distribution hub enables.
Houston is the B2B e-commerce capital of the American energy industry — a city where 4,600+ energy companies, the nation's largest medical complex (Texas Medical Center), and the largest port in the US by foreign waterborne tonnage (Port of Houston) create industrial and enterprise e-commerce demand at a scale that consumer-focused coastal markets don't approach. Houston's e-commerce market is overwhelmingly B2B: the energy industry alone drives $50+ billion in annual equipment, parts, and supply procurement — most of which still happens through phone calls, email, and paper catalogs. The digitisation of this procurement represents the single largest B2B e-commerce opportunity in the United States. Beyond energy, Houston's e-commerce ecosystem includes: medical supply (the Texas Medical Center's 60+ institutions procure billions in medical equipment, supplies, and pharmaceuticals), chemical and materials (Houston's petrochemical corridor — the largest in the Western Hemisphere — drives industrial chemical commerce), and a growing D2C segment fueled by Houston's 7.3 million metro population (the fourth-largest US metro, with significant Hispanic, Asian, and African American communities). Houston's logistics advantage is unmatched for heavy and oversized goods: the Port of Houston handles 247 million tons annually, the city has 8 Class I railroad connections, and the interstate highway system connects Houston to every major Gulf Coast and Texas market. For e-commerce companies shipping physical products — especially large, heavy, or hazardous goods — Houston's logistics infrastructure reduces shipping costs and delivery times across the Southern US. Texas regulatory requirements include: Texas sales tax (6.25% state + up to 2% local, with complex exemptions for manufacturing equipment, certain industrial supplies, and some medical devices), TDPSA (Texas Data Privacy and Security Act), and Texas franchise tax reporting for e-commerce businesses operating in the state.
Houston's e-commerce demand spans energy and industrial supply, medical equipment, chemical commerce, and consumer D2C. Energy and industrial supply: the single largest e-commerce opportunity. Applications: oilfield equipment and parts (drill bits, valves, pumps, sensors, and safety equipment — B2B commerce with technical specifications, compatibility checking, and hazmat shipping compliance), MRO supplies (maintenance, repair, and operations — industrial consumables, PPE, tools, and facility supplies for refineries, platforms, and offices), industrial instruments (pressure gauges, flow meters, analyzers, and control equipment — technical products requiring configuration and compatibility verification), and safety equipment (PPE, gas detection, fire suppression, and safety signage — required by OSHA, with compliance documentation included with purchases). Medical equipment and supply: TMC's procurement needs. Applications: medical devices (surgical instruments, diagnostic equipment, and implants — regulated commerce requiring UDI tracking, lot management, and FDA compliance documentation), medical consumables (gloves, masks, syringes, and wound care — high-volume recurring purchases with institutional pricing), laboratory supplies (reagents, culture media, and lab equipment for TMC's research institutions), and pharmaceutical supplies (hospital pharmacy procurement — controlled substance compliance, cold chain requirements). Chemical and materials: Houston's petrochemical corridor. Applications: bulk chemical ordering (industrial chemicals purchased by the tanker truck, rail car, or drum — with SDS documentation, hazmat compliance, and TSCA reporting), specialty chemicals (laboratory and manufacturing chemicals in smaller quantities — with purity specifications and certificates of analysis), and materials sourcing (metals, plastics, and composite materials for Houston's manufacturing sector). Consumer D2C: Houston's diverse 7.3 million metro population. Categories: Hispanic food and lifestyle (Houston's 45% Hispanic population drives specialty food, beauty, and cultural product D2C), BBQ and food culture (Houston's BBQ and culinary scene drives food D2C — sauces, rubs, smoked meats, and cooking equipment), outdoor and marine (Gulf Coast recreation — fishing, boating, and outdoor gear D2C), and energy transition consumer products (solar panels, EV chargers, and home energy products for the environmentally-conscious Houston consumer).
E-commerce development in Houston requires three capabilities: industrial B2B commerce architecture, hazmat and compliance logistics, and the scale-ready infrastructure that Houston's enterprise customers demand. Industrial B2B architecture: Houston's B2B customers need commerce far beyond consumer storefronts. We build: technical product search (parametric search across thousands of specifications — find a valve by pressure rating, material, size, connection type, and ANSI class — Houston engineers search by specs, not by browsing), customer-specific pricing (contract pricing, volume tiers, and blanket purchase orders — each customer account shows their negotiated prices), quote and approval workflows (B2B purchases often require internal approvals — the platform supports quote generation, approval routing, and PO-based ordering), ERP integration (SAP, Oracle, and industry-specific ERPs — bidirectional sync for pricing, inventory, orders, and customer data), and punchout catalogues (cXML/OCI punchout enabling Houston enterprises to purchase from within their procurement systems — SAP Ariba, Coupa, and Oracle). Hazmat and compliance logistics: Houston commerce frequently involves regulated materials. We implement: hazardous material classification (DOT hazmat classes, UN numbers, and proper shipping names — displayed on product pages and included in shipping documentation), SDS management (Safety Data Sheets linked to every chemical product — automatically included in order confirmations and accessible from order history), export controls (EAR and ITAR classifications for energy equipment sold internationally — Houston companies export globally), and certificate management (material test certificates, calibration certificates, and conformity documents — linked to specific product lots and accessible from order history). Scale-ready infrastructure: Houston enterprise B2B processes high volumes. We build: high-volume catalogue management (100,000+ SKUs with complex technical attributes — PIM integration for product data management), multi-warehouse inventory (Houston warehouse, Permian Basin depot, Gulf Coast port facility — real-time inventory across locations with shipping optimisation), bulk ordering (cart systems that handle 500+ line items per order — industrial POs often include hundreds of different parts), and EDI integration (electronic data interchange for large enterprise customers — purchase orders, invoices, and advance shipping notices exchanged electronically).
Energy / Industrial Supply
A Houston-based industrial supply company ($340 million annual revenue, serving 2,800 customers across the Gulf Coast energy sector — refineries, petrochemical plants, offshore platforms, and midstream operations) was processing 92% of its orders through phone calls and emailed POs. The manual process consumed 45 sales representatives' time, created order errors (4.2% error rate — wrong part, wrong quantity, or wrong shipping), and made it impossible for customers to check pricing and availability outside business hours. Customers had been asking for online ordering for years, but the company's catalogue of 180,000 SKUs with customer-specific pricing was too complex for generic e-commerce platforms. Competitive pressure: three national industrial distributors (Grainger, MSC Industrial, and Fastenal) had invested millions in digital commerce — Houston customers were beginning to shift purchases to competitors who offered 24/7 online ordering with real-time availability.
We built a B2B industrial supply portal with parametric search, customer-specific pricing, and SAP integration. (1) Parametric technical search: engineers find products by specifications, not by browsing categories. A search for "gate valve" narrows by: size (2" through 24"), pressure class (150# through 2500#), material (carbon steel, stainless, alloy), end connection (flanged, threaded, butt-weld), and standard (API 600, API 602, API 603). Each product page displays: technical drawing, material specifications, compliance certifications (ASME, API, NACE), and installation guides. Cross-reference: entering a competitor's part number shows the equivalent in-stock product. (2) Customer-specific pricing from SAP: real-time pricing pulled from SAP when authenticated customers browse. Contract prices, volume discounts, and customer-specific agreements displayed instantly. Guest visitors see list prices with "Log in for your price" messaging. (3) Real-time inventory across 3 warehouses: Houston main (140,000 SKUs), Corpus Christi depot (45,000 SKUs for refinery corridor), and Midland depot (32,000 SKUs for Permian Basin). Product pages show: "142 units at Houston warehouse — ships today" / "28 units at Midland — ships tomorrow to Permian Basin locations." Expected restock dates for out-of-stock items. (4) SAP bidirectional integration: orders placed on the portal create sales orders in SAP automatically. Pricing conditions, payment terms, credit limits, and shipping preferences all inherited from SAP customer master data. Order status, tracking, and invoice history visible in the customer portal — pulling from SAP in real-time. (5) Punchout and EDI: for the largest customers (refineries and petrochemical plants using SAP Ariba), cXML punchout enables purchasing from within their procurement system. EDI 850 (PO) and 810 (invoice) for customers requiring electronic document exchange.
Online revenue: $48 million in the first 12 months (14% of total revenue migrated online). 34% of online orders placed outside business hours — revenue that was previously lost to competitors. Order accuracy: online orders have 0.3% error rate (from 4.2% for phone/email — 93% reduction). The parametric search and SAP pricing integration eliminate the most common errors: wrong part selection and wrong pricing. Sales team efficiency: the 45-person sales team was restructured — 15 reps now focus on high-value consultative selling (project quotes, technical recommendations) rather than transactional order entry. Transactional customer calls decreased 62%. Average order value: $4,800 online (vs. $3,200 phone — 50% higher). The product recommendation engine ("customers who bought this valve also bought these gaskets and bolts") drives larger baskets. Customer retention: 94% of customers who adopted the portal remained active at 12 months (vs. 88% overall retention) — digital customers are stickier. New customer acquisition: 180 new customers in the first year who found the company through Google searches for industrial products — the SEO-indexed product pages created a new acquisition channel. Development investment: $420,000 over 18 weeks.
