B2B Ordering Portal: Trade Accounts Order on Terms

A B2B ordering portal for approved trade accounts: they buy online with a PO number, see stock and get invoiced on terms, with staff checking each purchase.

A B2B ordering portal lets approved trade accounts log in, buy from their own catalog with a PO number and get invoiced on their terms, instead of emailing requests someone keys in by hand. Each account sees its own prices, minimums and stock. Your staff still review every order before it is accepted.

This guide is for wholesalers, distributors, trade suppliers and makers who sell to stores or contractors and still take orders by email and phone. Order entry is one of the office jobs in our AI for manufacturers hub, and our AI for small business guide shows where a portal fits beside the AI agents.

What a B2B ordering portal should do

A B2B ordering portal should match the way approved accounts already buy from you: on account, with their own PO number, at their own prices and minimums. It should show stock before they commit, hold freight orders for a quote, and turn every accepted order into an invoice on their terms.

That is what separates a wholesale B2B portal from a store for the public, where everyone pays by card at one price. Any B2B ordering system rests on three records.

  • Accounts. Who may order, their terms, ship-to addresses and tax status in each state.
  • Catalogs and price lists. The items each account may buy, at its prices and minimums.
  • Orders. The PO number, lines, requested date, freight method and status.

Why do email orders and web stores fall short?

Email orders fall short because a person has to read each one, check stock, look up the account's price and key it in. Web stores fall short because they are built for shoppers paying by card. Neither keeps a PO number, a contract price and a freight quote together in one record.

Wholesale add-ons for store builders help when your accounts fit their boxes. Four gaps usually remain.

  • Card-first checkout. Trade buyers pay on terms, not at the register.
  • One price for everyone. Many have no price list per account, and no minimums.
  • No freight step. A pallet order needs a quote before anyone says yes.
  • No review. Orders go straight through, even when stock is short or an account is past due.

A small grower that sells to restaurants meets the same gaps every week; see small farm management software.

What we build: a trade ordering portal, screen by screen

We build a B2B online ordering system for your accounts and a back office for your staff. Accounts get approved sign-up, their own catalogs and price lists, ordering on terms with a PO number, live stock and reorder. Staff get a freight quote step, a review queue, invoices synced to your books and drafts from emailed orders.

On our Solutions page this is a full web application, with logins for each account's buyers and roles for your staff.

  1. Account sign-up. A business applies, and staff approve it before it can order.
  2. Catalog per account. Each account sees the items it may buy, its own price list and its minimums.
  3. Order on terms. The buyer enters a PO number and orders on account, with no card needed.
  4. Stock before ordering. Each line shows what is on hand, so a buyer knows about a short item first. A third-party warehouse keeps its own counts in small warehouse management software.
  5. Freight quote. Freight orders wait for staff to add a shipping quote for the buyer to accept.
  6. History and reorder. Past orders and a one-click reorder.
  7. Review queue. Every new order lands with staff, who check stock, prices and terms before accepting it.
  8. Invoice from the accepted order. It syncs to your accounting software.
  9. Drafts from emailed orders. For accounts that keep emailing, a draft appears in the queue.

AI reads a PDF purchase order, a photo of a handwritten list or a plain email and builds a draft order for staff to check against stock and the account's terms. We can set up the Admin Agent to sort the order inbox so each draft reaches the right person. Your staff approve every order, stock check and shipping quote before it is accepted.

Depending on the package, you get the right to use the portal we build or full ownership of it, and your accounts, price lists and order history stay yours.

How do we build and pilot it?

We write a spec of your accounts, price rules, terms and freight steps, then pilot the portal with a handful of trade accounts who order often. Your staff work the review queue during the pilot, so problems with prices, stock or freight show up on real orders before every account gets a login.

Before we hand it over, we test these five things.

  1. An account sees only its own prices and minimums, never another account's.
  2. No order is accepted until staff review it, and freight orders wait for a quote.
  3. An accepted order raises one invoice on the right terms, and it reaches your accounting software once.
  4. Stock in the portal matches your inventory system.
  5. An emailed test order becomes a draft with every line matched or flagged.

If the portal shows ship dates, keep them honest. The FTC's mail, internet and phone order rule (opens in a new tab) asks for a reasonable basis for any shipping time a seller promises, and a seller who runs late must get the customer's consent to the delay or refund the money. Ask your attorney how it applies to your trade accounts.

This is an illustration, not a customer story. Ingrid handles order entry at a wholesaler that sells cleaning supplies to stores and contractors. A contractor asks for two pallets with a PO number, and the order reaches Ingrid's queue with a freight line waiting. Ingrid checks the stock, adds the quote, and the buyer accepts it. A store that still emails sends a photo of a list, and the draft flags one unmatched line for Ingrid to fix.

Resale certificates for Kansas and Missouri accounts

Wholesalers in the Kansas City metro often sell to stores in both states, and each state has its own resale exemption certificate. The portal keeps each account's certificate on file by state and flags an order from an account with none, so your staff can ask for it before the sale.

In Kansas, a buyer claiming a sales tax exemption, such as buying for resale, gives the seller a completed exemption certificate, and the seller keeps it on file with its sales tax records, as the Kansas Department of Revenue's certificate guide (opens in a new tab) explains. In Missouri, a business buying goods to resell gives the seller a completed state sales and use tax exemption certificate, and the seller collects it, according to the Missouri Department of Revenue's business tax FAQ (opens in a new tab).

The two states use different forms, so the portal never files one state's certificate as the other's. Whether a sale is taxable is a question for your accountant or tax advisor.

What stays with your staff?

Every call about credit, price and promises stays with your staff. People approve new accounts and set their terms, set every price list, confirm stock and freight before an order is accepted, and handle any order that looks wrong. The portal and the AI do the typing, matching and filing.

Trade credit is a judgment for your owner or bookkeeper. The portal shows what an account owes and how it pays, and it never opens or raises a credit line on its own. Following up with accounts that have gone quiet is CRM work, covered in our guide to CRM automation for distributors. Same team. Same jobs. More capacity.

Frequently asked questions

What is a B2B portal?

A B2B portal is a private website where a supplier's business customers log in to buy, check stock, see their prices and view past orders and invoices. Only approved accounts get in, and each one sees its own catalog and terms instead of a public price list.

What is B2B ecommerce?

B2B ecommerce is selling goods online from one business to another, such as a wholesaler to a store or a supplier to a contractor. Orders often carry a PO number, are paid on terms instead of by card and may need a freight quote before they ship.

What is a wholesale account?

A wholesale account is a business customer approved to buy from a supplier at trade prices, usually to resell or to use in its own work. It has its own price list, minimums, ship-to addresses and payment terms, plus the resale certificate its state asks for when it buys to resell.

How do wholesale accounts work?

A business applies, the supplier checks it and approves it, and the account gets trade prices, minimums and terms. The buyer orders with a PO number, the supplier ships and invoices on the agreed terms, and the account pays by the due date. The supplier's people set credit limits and terms.

How do you sell wholesale products to retailers online?

Give approved retailers a private login where they see your wholesale catalog, their prices, minimums and live stock. Let them order with a PO number on terms, review each order before you accept it, and keep their resale certificates on file for the state they buy in.
