The Consumer-Grade Ordering Experience Your B2B Buyers Already Expect

On a Tuesday night, a purchasing manager at a regional mechanical contractor goes online to order a replacement part for her dishwasher. Unfortunately, the part she wanted is out of stock, but the website does have another option that’s compatible with her make and model. She goes to checkout and changes the delivery address, because the day it's supposed to arrive, Thursday, is also when she’s supposed to be visiting her sister a few hours away. Then, she goes to bed, and the next afternoon she gets a notification that it's shipped. 

The next morning she logs into her distributor's portal to order 400 pipe fittings for a commercial HVAC installation scheduled for Monday. The portal simply says "in stock." She gets a confirmation email with only an order number. There’s no delivery date. By 10 a.m. the job site has moved, so she calls her rep to see if she can change the ship-to address. She waits on hold, but everyone is busy. She leaves a voicemail and mentally crosses her fingers, her frustration building,  

Why is it so easy to order and get shipping updates on a dishwasher part, while placing a pipe fitting order is like pulling teeth? 

Whether she’s ordering for herself or for her company, the purchasing manager still wants the same basic experience: accurate availability, a delivery commitment, shipment updates, and a way to make changes without making a call.  

She wants an Amazon-grade order experience for B2B. 

Consumer Expectations are Shaping B2B Buying 

It is tempting to argue that professional buyers are different from shoppers, but you have to remember that professional buyers are also consumers in their personal lives. They buy household goods and business supplies, and the experience they get in one context shapes what they expect in another. 

Recent research puts numbers behind those expectations: 

• A Gartner survey of B2B buyers found 67% prefer a rep-free buying experience.  

• In a separate 2025 survey of professional buyers, 40% named a lack of transparency around stock and delivery dates as their top frustration, only 19% said their online buying experience met expectations, and 75% said they would consider switching suppliers for a smoother one. 

In many cases, B2B buying is more complicated, but that’s exactly why distributors should raise their performance bar. When a consumer's parcel is late, they get annoyed. When a contractor's fittings are late, the installation can’t happen, crews lose work, and the business reputation hangs in the balance. 

The complexity of an order shouldn’t change what the buyer gets from the experience.  

Six Questions Every B2B Order Should Answer

Every B2B buyer should be able to answer the same six practical questions, just like a typical consumer, before and after placing an order. The answers may depend on account rules, inventory, fulfillment options, and delivery constraints, but the buyer shouldn’t have to chase them down.  

Can I get it? 

"In stock" is a half-truth. It doesn’t tell a B2B buyer whether the product is available for their specific order.  

Most distributors hold inventory across distribution centers, branches, suppliers, drop-ship partners, and purchase orders already in transit. A portal that reads one balance will turn away orders you could fill and accept orders you cannot. 

Unlike consumer retail, B2B availability depends on who is ordering and where the order needs to go. Stock held for a contract customer or at a location that cannot reach a particular buyer's site in time is not available, and neither is reserved inventory. 

The portal should show whether the distributor can supply a certain quantity to a customer, at a specific location, by a specific date.  

When will it arrive? 

Buyers treat the delivery date as a commitment. 

In B2B that date must account for the quantity, the receiving site's delivery calendar, any shipping restrictions, whether the order is for next week or next quarter, and whether part of it is still on a supplier's truck. 

Much like a GPS that says you’ll arrive at 6:30 and gets you there on time, versus GPS that promises you’ll arrive at 6:00 but then takes you down a short cut through a blocked road, a slow, honest date beats a delivery date that the distributor can’t keep.  

Buyers schedule crews and production runs around the delivery date they receive, so if your system cannot provide a reliable commitment at order entry, you are asking the buyer to carry the risk for you. And, if you accept an order only to call later and tell them the items were actually out of stock, you are risking the relationship, and your reputation as well. 

What if it's out?  

When ordering goods at home, "out of stock" often comes with an alternative option, like a generic brand for the dishwasher part. For a B2B purchase, however, an “out of stock” item can mean a lost sale, especially when the buyer has to call, or wait to get more information.  

B2B sellers have more ways to fulfill an order when a requested item is unavailable than consumer retailers do. They can offer an approved substitute, inventory from another location, a purchase made specifically for this order, or a drop shipment from a supplier. Each fulfillment option may come with its own price, quantity, and delivery date. But, regardless of the options, the buyer only cares that the alternate meets their needs, what it will cost, and when it will arrive. 

Will it come together? 

Consumers are likely to be satisfied no matter if their package comes in one box, or two. Business buyers often have tighter receiving requirements, because every delivery costs them receiving labor, and their delivery windows can be much, much smaller.  

Delivery requirements vary by account. One customer may need the entire order in one shipment, while another may accept split deliveries once a minimum share is ready, and some job sites can only receive materials during a narrow window of time.  

Those fulfillment preferences may be set by the customer, order, location, or delivery type, and should be carried forward from order to order and applied automatically at checkout, making each purchase easier to place. 

Where is it? 

Tracking is a super common consumer e-commerce feature, but it's one thing that B2B struggles with. B2B orders often move through several locations and arrive in separate shipments, so a single tracking number can’t give buyers a full picture. 

Buyers need visibility into partial shipments, backorders, planned deliveries, and changes to the original commitment. When a delivery is at risk, an early alert gives the buyer time to adjust the schedule, crew, or delivery plan, and doing so turns a surprise at the dock into a disruption both sides can manage together.  

Can I change it? 

Project plans rarely get executed as the original plan, and so B2B orders change constantly. A delivery may need to follow a moved job site, accommodate a slipped schedule, or cover a larger quantity than originally planned. 

In consumer retail, the buyer can often make these changes themselves. In wholesale, a simple change can pull multiple team members into the work. They have to confirm the order status, update the shipping address, notify the right people, and make sure the change reaches the shipment. The business pays for all of that coordination in labor, slower responses, and greater risk of error. 

When a buyer asks, "Can I just do it myself?", they just want a controlled way to quickly make a change before the warehouse releases an order. A self-service portal should provide enough control for the buyer to keep the project moving, such as changing the delivery address or date, while the seller gets to keep its pricing, delivery rules, and approval controls.  

Is a Better B2B Portal Enough to Deliver Accurate Availability or Delivery Dates? 

Look at those six questions again. Each depends on current facts and business rules. A late supplier shipment, full truck, or changed delivery location can change what the business can promise, and each decision must be recalculated. 

A portal, the buyer-facing interface, can display core business records from the ERP, such as customer accounts, terms, pricing, billing, and payments. But the ERP cannot analyze and orchestrate   What can be promised to whom and how to fulfill it at the lowest cost. As one Manhattan B2B customer, a European distributor, put it: "We selected the ERP for great financials, but we needed more agility for ordering and fulfillment." 

Adding another setting or custom report to the ERP may solve an individual case, but it doesn’t give the ERP a new decision-making capability. The business needs a layer that uses the ERP’s facts to calculate what can be promised and how the order should be fulfilled.  

How to Improve B2B Ordering Without Replacing Your ERP 

Most teams first try to modify the ERP whenever they need more precise availability, account-specific rules, or daily order monitoring. While each fix may solve one particular scenario, together they can make the ERP harder to upgrade, harder to change, and more dangerous to touch. Waiting for an ERP upgrade or replacement, if it even has the capability, takes years. 

Rather than stretch the capabilities of an ERP, allow it to do what it does best, and keep it as your system of record. Then, add a promise and fulfillment layer around it that can make the decisions and calculate what the business can offer around availability, delivery commitments, and fulfillment options. The clear division of operations preserves the ERP’s core and provides buyers with one consistent view. 

This approach isn’t theoretical and produces measurable results. One Manhattan wholesale customer moved 25% of their customers who had been ordering manually onto digital ordering. It raised first-time fill rates from about 60% to more than 90%, and it cut order cycle time for its most critical service-level orders from two and a half days to half a day. 

How to Test Your B2B Ordering Experience  

The “12-hour test” compares the same buyer’s consumer and B2B experiences that can often happen within the span of a day.  

Ask someone on your team to place an order through the portal, then change the delivery address, date, or quantity, and ask: 

• Did the portal show what that customer could actually buy, for delivery to their site? 

• Did they get a date at order entry? Would you stake the account on it? 

• When an item was short, did they get an alternative, or just a backorder? 

• Could they see every part of the order, including partial shipments and backorders? 

• Could they make a change without calling anyone? 

• Would your rep, your service desk, and your EDI feed have given the same answers? 

Every "no" answer identifies a break in the promise your portal makes. It shows where the buyer has to guess, call, or wait, and where your team has to step in manually. If you can fix these moments, the portal can become a reliable way for buyers to get the information they need about an order, and what they can change.  

What Should a Modern B2B Ordering Experience Deliver? 

 A modern B2B ordering experience gives buyers confidence at every step. They should know: 

•  Whether an order can be filled for their account and delivery site 

• When it will arrive 

• What happens when an item is short 

• How the order will be delivered 

• Where each shipment is 

• What they can change themselves 

Manhattan Enterprise Promise & Fulfill helps distributors deliver those six moments without rebuilding the ERP. The ERP remains the system of record, while a promise and fulfillment layer calculates account-specific availability, committed delivery dates, fulfillment options, shipment updates, and eligible order changes. Buyers get the clarity and control they expect, while distributors keep the business rules and core systems they rely on. 

Your buyers already know what confidence feels like when they place an order. When the next order is 400 units headed to a job site, and the plan changes before the truck leaves, will your systems give them an answer, or make them call to find one?
