In the Census Bureau's 2023 County Business Patterns, the metro had 3,224 wholesale trade and 2,220 manufacturing establishments, and the US Army Corps of Engineers ranked the St. Louis Metro Port, IL and MO, fourth among U.S. port statistical areas in 2023, with 24.0 million short tons. Uncap integrates Shopify with ERP systems from 13 vendors. Blueprint, Uncap's planning step, costs $7,500 and takes four weeks, and a migration from another platform typically takes 10 to 16 weeks. Uncap's team, based at its Chicago headquarters, travels on site for kickoff and key milestones. Uncap is a Shopify agency that builds B2B commerce for manufacturers, distributors and wholesalers in St. Louis, on both the Missouri and Illinois sides of the metro. Uncap is a Chicago-based Shopify Platinum Partner. Uncap's team, based at its Chicago headquarters, travels on site for kickoff and key milestones. ## Freight on the Mississippi, measured by the Corps of Engineers In the US Army Corps of Engineers' table of U.S. port statistical areas in 2023, the St. Louis Metro Port, IL and MO, ranked fourth, with 24.0 million short tons, down 7.0 percent from 2022. All of that tonnage was domestic. The City of St. Louis Port Authority describes the Port of Metropolitan St. Louis, as the Corps defines it, as 70 miles long and covering both sides of the Mississippi River. The authority lists service by 6 Class One railroads, 7 Interstates and 2 international airports, and access to two Foreign Trade Zones. Trucks and warehouses carry the freight off the river. According to the Bureau of Labor Statistics, the metro had 61.4 thousand jobs in transportation, warehousing, and utilities in September 2026 (preliminary), against 61.8 thousand a year earlier. In the Census Bureau's 2023 County Business Patterns, the metro counted 1,330 truck transportation establishments with 17,292 employees, and 205 warehousing and storage establishments. On a Shopify B2B store, a buyer that receives at several sites can have each one set up as its own company location, with its own shipping address and payment terms. ## Fourteen counties and St. Louis city, across two states The St. Louis, MO-IL metro, as the Census Bureau and the Bureau of Labor Statistics name it, spans eight Illinois counties, including Madison County and St. Clair County, six Missouri counties, and St. Louis city, which the Census Bureau lists on its own. Wholesale establishments outnumber manufacturing establishments here. In the Census Bureau's 2023 County Business Patterns, the metro had 3,224 wholesale trade establishments with 63,455 employees, and 2,220 manufacturing establishments with 110,031 employees. Of those wholesalers, 1,964 were merchant wholesalers of durable goods and 877 were merchant wholesalers of nondurable goods. Machinery, equipment and supplies merchant wholesalers made up the largest wholesale industry group by establishments, with 493 establishments and 8,470 employees. Grocery and related product merchant wholesalers counted 203 establishments with 6,511 employees. Count jobs instead, and manufacturing is the bigger employer. According to the Bureau of Labor Statistics, the metro had 118.4 thousand manufacturing jobs in September 2026, against 115.9 thousand in September 2025, and 64.7 thousand wholesale trade jobs, against 65.0 thousand in September 2025. Total nonfarm employment stood at 1,435.7 thousand. The September 2026 figures are preliminary and not seasonally adjusted. If you stock and resell, Uncap's page on [Shopify for distributors](/solutions/distributors) covers large catalogs, tier pricing and bulk ordering from the distributor's side. ## Aircraft parts, chemicals, metal and food: what St. Louis makes The Census Bureau's 2023 County Business Patterns counts these manufacturing subsectors in the metro, among others: - Transportation equipment: 81 establishments, including 17 in aerospace product and parts manufacturing. - Chemical manufacturing: 149 establishments with 12,552 employees, including 28 pharmaceutical and medicine manufacturing establishments. - Fabricated metal products: 442 establishments with 12,094 employees, the most establishments of any manufacturing subsector in the metro. - Machinery manufacturing: 170 establishments with 10,702 employees. - Food manufacturing: 217 establishments with 8,036 employees. Beverage manufacturing adds 78 establishments with 4,022 employees, among them 31 breweries. Selling these products online takes different tools. Uncap's [machinery and equipment parts page](/industry/machinery-equipment) shows how a buyer can start from the machine and click the part they need straight off an interactive exploded diagram and add it to the cart. Food and beverage sellers deal with catch weight, lot and expiry traceability, and cold chain, which Uncap's [food and beverage page](/industry/food-beverage) covers. For a fabricator, a machinery builder or a chemical producer that sells to trade accounts, start with how Uncap approaches [Shopify for manufacturers](/solutions/manufacturing). ## Trade accounts, catalogs and terms in Shopify B2B Shopify B2B is available on the Basic, Grow, Advanced, and Plus plans, so a St. Louis wholesaler does not need Shopify Plus to start taking trade orders. The plan you pick changes how many catalog assignments you can have active. Shopify organizes B2B buyers into companies. A company is the parent organization for one or more company locations, and a company location is the business you sell to. For a buyer with several sites, you keep all of their information in one company profile, and a company can have up to 10,000 company locations. When a buyer has access to more than one location, Shopify prompts them to choose which one they are ordering for. Three settings shape what each account sees and how it pays: - Catalogs: a B2B catalog chooses which products and prices a buyer is offered. Catalogs can apply percentage price adjustments and fixed prices, set volume pricing for price breaks, and set quantity rules. - Catalog limits: on the Basic, Grow, and Advanced plans, a store can have up to 3 active catalog assignments across active B2B markets. That limit does not apply on Shopify Plus, where catalogs can also be assigned directly to company locations. - Payment terms: payment terms define how long a company has to pay for an order. Shopify offers net 7, net 15, net 30, net 45, net 60 and net 90, plus due on fulfillment and a fixed date, and you can set terms for each company location. Settle how many price groups you run before you pick a plan. That number tells you whether three catalog assignments are enough or whether Plus is the better fit. ## Connecting your ERP to the Shopify store Uncap integrates Shopify with ERP and back-office systems from 13 vendors: Acumatica, Cin7, Epicor, Fishbowl, Infor, Microsoft Dynamics, NetSuite, Odoo, Oracle, QuickBooks, Sage, SAP and Syspro. Each vendor has its own page in the [Uncap integrations directory](/integrations), often with pages for individual products such as Epicor Prophet 21 or Sage 100. Your ERP remains the system of record after launch. Uncap's build work includes the ERP and system integration, and an ERP integration audit is part of Uncap Blueprint. Depending on the system, the integration runs through [Uncap Connect](/products/connect) or a managed integration. Uncap Connect starts at $8,000 for onboarding and then a flat $390 per month. For a specific ERP and the depth of sync your operation needs, the Uncap team confirms fit directly. Two of the case studies below show ERP work in production: ULE Group runs Epicor ERP behind its Shopify B2B storefront, and Kooks runs Infor Visual ERP behind a store that serves retail and wholesale buyers. ## Prices and timelines Uncap publishes Uncap publishes its entry prices and typical timelines, so you can size a project before the first call: - Uncap Blueprint: $7,500 at a fixed price, delivered in four weeks. You get a migration playbook, solution architecture, a data migration taxonomy, an SEO preservation roadmap, an ERP integration audit, UX and flow prototyping, stakeholder workshops and a replatforming risk register. The plan is yours to keep, and the fee is credited 1:1 toward implementation. - The build: fixed scope, with timeline and budget agreed before the build starts. A new build runs about 12 weeks from discovery to launch. - A migration: a move from another platform typically takes 10 to 16 weeks, and Uncap's median cutover is around 14 weeks. - Adding B2B to a store you already run: unifying B2B and B2C on an existing Shopify store takes 4 to 8 weeks. - Uncap Connect: $8,000 for onboarding, then $390 a month. - After launch: an ongoing monthly engagement for conversion, order value, retention and operations, with plans from $2,500 a month. Uncap Blueprint is an engagement for operators doing $5M+ in revenue. If you are not sure whether you need it, ask in the first conversation whether your project is ready for a fixed-scope build or needs the plan first. See [Uncap Blueprint](/blueprint) for the full scope. ## Six steps from plan to launch Whether you are moving from another platform or opening B2B ordering for the first time, the work breaks into these steps: - Plan the build. Uncap Blueprint maps architecture, integrations and total cost of ownership over four weeks. - Kick off on site. Uncap's team, based at its Chicago headquarters, travels to your plant, warehouse or office, in Missouri or Illinois, for kickoff. - Agree scope and date. The timeline and budget are set before the build starts. - Build and integrate. A senior team handles architecture, design, theme and app development, ERP and system integration, and data migration with SEO redirects. Uncap's Shopify development services page lists the full scope. - Review milestones in person. Uncap's team comes back on site at each key milestone. - Launch and keep improving. Launch comes with hypercare. After that, ongoing growth work can raise margin per order and average order value and build retention through email automation, self-service portals and quick reorders. If you are replatforming, the [Shopify migrations](/migrations) page explains each phase of the move in more depth, from the data audit to redirect mapping, testing and cutover. ## Uncap clients in distribution and manufacturing Neither client below is based in the St. Louis metro.

No. Shopify B2B is available on the Basic, Grow, Advanced, and Plus plans. A store on the Basic, Grow or Advanced plan can have up to 3 active catalog assignments across active B2B markets. Shopify Plus removes that limit and lets you assign catalogs directly to company locations, which matters when many accounts need their own pricing. ### Can one customer account cover several plants or warehouses? Yes. In Shopify B2B, a company is the parent organization for one or more company locations, and a company can have up to 10,000 locations. Each location can have its own shipping address, billing address and payment terms. A buyer with access to more than one location is prompted to choose the one they are ordering for. ### Which ERP systems does Uncap connect to Shopify? Uncap integrates Shopify with ERP and back-office systems from 13 vendors: Acumatica, Cin7, Epicor, Fishbowl, Infor, Microsoft Dynamics, NetSuite, Odoo, Oracle, QuickBooks, Sage, SAP and Syspro.

Uncap Blueprint, the planning step, is a $7,500 fixed-price plan delivered in four weeks, with the fee credited 1:1 toward implementation. Builds are fixed scope, with timeline and budget agreed before work starts. Uncap Connect starts at $8,000 for onboarding and then $390 a month, and ongoing work after launch runs from $2,500 a month. ### How many weeks does a Shopify migration take? A migration from another platform typically takes 10 to 16 weeks, and Uncap's median cutover is around 14 weeks. A new build runs about 12 weeks from discovery to launch. If you already sell on Shopify, unifying B2B and B2C on that store takes 4 to 8 weeks. Uncap Blueprint, the planning step, is delivered in four weeks. ### Can trade buyers get volume pricing and order minimums? Yes. Shopify B2B catalogs let you set fixed prices or percentage adjustments, offer volume pricing with price breaks, and set quantity rules that limit how many units a buyer can order. Catalogs decide which products and prices each buyer sees, so two accounts can get different price breaks from the same store.
