Why a B2B ordering portal makes sense for United States

The United States is a market of about 340 million people where B2B and wholesale portals are growing fast, with Washington, D.C. as its capital.

The United States has more than 33 million small businesses, which make up 99.9% of all US firms (US SBA Office of Advocacy). The United States is the world's most valuable e-commerce market outside China, and shoppers expect fast, free shipping, easy returns and wallet checkout. Direct-to-consumer brands that own their store and data, rather than relying only on marketplaces, keep more margin and customer loyalty.

That is why more companies in United States are moving from phone, WhatsApp and spreadsheet orders to a proper B2B ordering portal — one place where products, prices, payments, orders and customers are managed together.

Local details we build into every United States project

Conversion in United States depends on small local signals — the right currency, the right words and the right payment and courier names.

Currency and pricing

The store speaks US dollar: USD amounts from product page to invoice, so United States buyers never convert in their heads.

Language and content

Content can be produced in English and Spanish, so a United States customer reads the store in the language they use at home.

Local trust signals

Trust is local: familiar names such as Visa, Mastercard, Amex and Discover and PayPal and Venmo and USPS sit next to the buy button.

Domain, phone and contact

Using .us where it suits you signals a local business to shoppers and search engines. Click-to-call and WhatsApp buttons use the +1 calling code so customers reach you without dialling errors.

A B2B ordering portal built around your United States business

If you run a business in United States and want to sell online, we build an e-commerce platform and mobile application to your exact requirements, from the first product page to the last delivery update.

In United States we typically work with wholesalers, FMCG distributors, industrial suppliers and electrical and hardware traders, and with sellers in categories such as electronics, apparel and footwear, health and personal care and home and furniture that have strong online demand in the United States.

Before any commitment you get a free requirements meeting, a demo built on your use case and a proposal priced to your budget.

What your B2B ordering portal includes

Each module below is configured — or custom-developed — to your requirements. You choose what launches first and what follows in later phases.

Business accounts

Registration, KYC and approval, company hierarchies, branches, buyers and approvers with their own permissions. Bulk import and sync tools mean the United States team never re-keys stock, prices or descriptions by hand.

Contract pricing

Price lists by customer, group or territory, quantity slabs, pack sizes, minimum order values and negotiated rates. Checkout is configured for Visa, Mastercard, Amex and Discover, PayPal and Venmo and Apple Pay and Google Pay.

Quick and bulk ordering

SKU-code entry, spreadsheet upload, saved lists, re-order from history and scheduled repeat orders. Couriers such as USPS, UPS and FedEx plug in alongside your own fleet for United States orders.

Quotes and approvals

Request-for-quotation, counter-offers, purchase-order upload and multi-level approval before submission. Multiple stock points in United States are supported, so a United States order ships from the nearest one.

Credit and payments

Online payment, credit limits, pay-later terms, outstanding statements and payment reminders where approved. Reports show which products, customers and areas of United States drive revenue.

Sales-team tools

Order on behalf of customers, territory assignment, visit notes and performance dashboards for representatives. Pages, search filters and wording are tuned to how people in United States look for products, in English and Spanish if your audience needs it.

Businesses that use NNT Mart in United States

Popular online categories in the United States include electronics, apparel and footwear, health and personal care, home and furniture, groceries and pet supplies. In United States, we most often build B2B and wholesale portals for:

Wholesalers

For wholesalers, we usually start with contract pricing, then add ERP (SAP, Oracle, Microsoft Dynamics, Tally, Zoho) once orders are flowing.

FMCG distributors

Catalogue, pricing and fulfilment rules designed for FMCG distributors in United States, connected to the systems you already use.

Industrial suppliers

Industrial suppliers get quick and bulk ordering plus credit and payments workflows tailored to their operations.

Electrical and hardware traders

We map how electrical and hardware traders sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.

Medical and institutional suppliers

For medical and institutional suppliers, we usually start with sales-team tools, then add credit and payment gateways once orders are flowing.

Dealer networks

Catalogue, pricing and fulfilment rules designed for dealer networks in United States, connected to the systems you already use.

Getting paid online in United States

Shoppers in United States rarely abandon a cart over price alone — they leave when their usual method is missing. Here that means Visa, Mastercard, Amex and Discover, PayPal and Venmo and Apple Pay and Google Pay, then Shop Pay, Affirm, Klarna and Afterpay BNPL and ACH bank payments.

We integrate suitable gateways and providers for your business category and merchant eligibility, handle payment status, failed-payment retries and refunds, and keep sensitive card data with the provider rather than on your servers. All amounts are shown in US dollar (USD).

  • Apple Pay and Google Pay
  • Affirm, Klarna and Afterpay BNPL
  • Visa, Mastercard, Amex and Discover
  • Shop Pay
  • PayPal and Venmo
  • ACH bank payments

Delivery and fulfilment across the United States

Your B2B ordering portal can book shipments and share tracking with USPS, UPS, FedEx, DHL eCommerce, Amazon Shipping and OnTrac, or route orders to your own riders and stores.

Delivery rules can price by distance, weight, postcode or zone, offer same-day slots in dense areas, and switch on pickup points or click-and-collect where customers prefer them.

Owning your channel in the United States

Amazon, Walmart Marketplace and eBay are where many shoppers in United States start, which is why sellers list there. The trade-off is commission, limited branding and rules the platform can change overnight.

NNT Mart gives you a channel you own: your domain, your customer list, your pricing and your brand. Where it helps, we connect product feeds and orders from marketplaces so stock stays in sync and your team works from one dashboard.

Compliance built into your B2B ordering portal

On tax: There is no federal VAT; 45 states and D.C. levy sales tax with local add-ons, and since South Dakota v. Wayfair (2018) remote sellers must collect tax once they pass each state's economic-nexus threshold.

Two frameworks shape the build: state privacy laws led by the California CCPA/CPRA (with similar laws in Virginia, Colorado, Texas and others), the FTC Act, COPPA for children and CAN-SPAM for email, and FTC rules including the Mail, Internet or Telephone Order Merchandise Rule, the 2024 rule against fake reviews, the ADA expectations on website accessibility and state "click-to-cancel" subscription laws.

Our job is the engineering: price display with tax, invoice numbering, cookie and marketing consent, return and terms pages, role-based access and logs. Legal and tax conclusions stay with your own adviser.

Mobile commerce in United States

In United States, shoppers browse on phones first. A dealer and sales-representative app lets buyers re-order in seconds, scan products, check statements and receive scheme announcements, while reps take orders at the counter even with patchy connectivity.

One backend serves the website and the apps, and the apps ship under your own Google Play and App Store accounts — so what you change once appears everywhere.

Order alerts, offers and abandoned-cart reminders go out on United States time (UTC−4), in English and Spanish if you want.

  • Credit and payment gateways
  • Warehouse and inventory systems
  • Logistics and freight partners
  • ERP (SAP, Oracle, Microsoft Dynamics, Tally, Zoho)
  • CRM and lead management
  • Accounting and e-invoicing
  • WhatsApp and SMS notifications
  • BI and reporting tools

Integrations above are examples; we connect any system that offers a suitable API, database access or approved import and export process.

A phased launch plan for United States

Value first, depth later. For a B2B ordering portal serving United States, the usual sequence looks like this:

PhaseWhat goes live
Launch portalAccounts, contract pricing, catalogue, ordering and ERP order sync. Configured for USD, Visa, Mastercard, Amex and Discover and USPS from the start.
AutomateQuotes, approvals, credit, statements and notifications.
ExpandDealer and sales-rep apps, analytics and new territories. Reviewed against how United States customers actually buy.

We track order-entry time, share of orders placed online, order accuracy, days sales outstanding, repeat-order frequency and sales-rep productivity on a live dashboard from day one, so United States results are visible, not promised.

How United States clients work with us

United States runs on UTC−4, which is 9h 30m behind India (IST). With three 8-hour shifts we are available 24×7, so meetings, demos and urgent fixes happen in your working hours.

We work in English and can deliver storefront content in Carolinian, Samoan and Hawaiian. NDAs are signed on request, and you get a named project lead plus direct access to the engineers building your B2B ordering portal.

Our head office is in Chhapi, Gujarat, with an office in Hyderabad and representation in Nigeria, South Africa, Ethiopia and Zambia; clients in the United States are served remotely with on-site workshops when the project needs them.
