Our dealers are used to ordering by phone. Will they actually use a portal?

They will not switch just because the portal goes live; it has to feel easier than picking up the phone. The most effective incentive is usually not a discount but information: on the portal they can see stock, shipping progress, order history, and statement details right away, all things that require waiting for a reply over the phone. Start by trialing it with a few dealers who order often and cooperate well, use their feedback to adjust the flow, and then roll it out gradually. During the transition keep phone ordering, but have sales assistants enter those orders on the portal for the dealer, so every order lands in the same record, and then gently guide dealers toward ordering themselves.

Can a dealer ordering portal and a regular e-commerce site run on the same system?

Some systems technically support both B2C and B2B, but the core logic differs a lot. B2C means public prices, immediate payment, and small single orders. B2B means prices and terms that vary by customer, monthly billing or credit within a limit, full-case or minimum order quantities, and quoting and approval steps. Forcing B2B needs into a B2C system usually turns into a pile of exception handling. A sturdier approach is to share the product master and inventory but handle ordering, pricing, and receivables separately, or to build the B2B portal on its own and have it share the same product data with the e-commerce site and the ERP.

Can dealers look up their own statements and invoices on the portal?

Yes, and it is one of the features that cuts back-and-forth questions the most. A common approach is to give the dealer back end statement, unpaid items, issued invoices, and payment history views with downloads, using the ERP or accounting system as the source of truth while the portal only displays it. Watch two things. First, sync lag: show when the data was last updated on screen so a dealer does not think a payment they just made was never received. Second, permissions: one dealer may have separate purchasing and accounting staff, so you need to set who can see receivables and who can only place orders.

How to Plan a B2B Dealer Ordering Portal

A sales assistant opens the computer in the morning to a dozen order messages in the chat app, the fax machine has spat out a few handwritten order sheets, and the phone keeps ringing: “Is that item still in stock?” “Did last week’s batch ship?” This is daily life for many manufacturers and brand distributors, and the typical starting point for planning a dealer ordering portal.

The biggest difference between B2B ordering and ordinary online shopping is that every customer has different prices, terms, and limits, and orders also have to go through approval, match inventory and the shipping schedule, and finally be reconciled and collected. Moving those rules out of sales assistants’ heads and spreadsheets into a system is where the portal’s real value lies.

What follows covers the problems a portal should solve, how tiered price lists and trade terms work, credit limits, how much inventory to show, order flow, reconciliation, and what to watch when integrating with an ERP.

What a dealer ordering portal should solve

Start by confirming where your pain actually is, so the portal’s scope does not drift. Common problems in practice:

Transcription errors: part numbers, quantities, or specifications are copied wrong and only discovered after shipping, making returns and exchanges expensive.
Repeated questions: dealers ask about stock, shipping progress, and balances, and sales assistants spend much of the day answering the same questions.
Prices and terms rely on memory: which price list and which special terms apply to which dealer is known only to the salesperson in charge.
Over-limit discovered too late: a dealer already owes a sizable balance, yet orders keep shipping.
Reconciliation drags on: at month end each side compares its own records, and every difference has to be chased line by line.

The aim of the portal is to let dealers order and look things up for themselves, freeing internal staff from copying orders and answering questions so they can focus on exceptions and account management.

Tiered price lists and trade terms: rules instead of memory

Prices on a B2B portal are not a single selling price but a set of rules. In design, split “how the price is decided” into several independent mechanisms, so business rules can be adjusted in the back end rather than changed in code every time:

Customer tiers: dealers are grouped by type or partnership level, and each tier maps to a price list.
Customer-specific prices: a particular dealer has an individually negotiated price on particular items, which takes priority over the tier price list.
Quantity breaks: the same item takes different prices depending on order quantity, with break thresholds and their prices set in the back end.
Time-limited promotions: special pricing for specified items or customer groups during a specified period, expiring automatically when the period ends.
Minimum order quantities and pack sizes: for example, full cases only, checked by the system at ordering time rather than sent back afterward.

When these mechanisms coexist, you must define their order of priority. When a customer-specific price and a promotion both apply, which wins? Do quantity breaks stack on top of the tier price list? These rules must be written clearly at the specification stage, and the screen should show dealers “how this price was reached,” which reduces disputes later.

You also need to decide price visibility. Can visitors who are not logged in see prices? Can dealers in different tiers see only their own price list? In most cases, prices on a B2B portal are shown only to logged-in dealers, and each sees only the list that applies to them. For how to layer accounts and roles, see User Roles and Permissions Design.

Credit limits: know whether you can ship before the order is placed

Monthly billing and trade credit are the norm in B2B, and credit limits are the key to controlling risk. What the system needs to do is decide at the moment of ordering, not discover the problem after shipping.

The basic design of credit limit control:

Define clearly what counts against the limit: does used credit include amounts ordered but not shipped, shipped but not invoiced, and invoiced but not collected? Different definitions give very different results, so settle it together with finance.
What happens when the limit is exceeded: block outright, allow the order but send it for approval, or require payment first; rules can differ by customer tier.
Link to overdue balances: decide in advance whether an overdue unpaid balance suspends ordering or allows only certain items.
Show available credit in real time: dealers see their current available credit on the order page, so orders are not rejected after submission.
Keep a record of adjustments: who approved a temporary increase, when it takes effect, and when it reverts should all be traceable.

The real source of credit data is usually the ERP or accounting system, and the portal must make sure it reads the latest receivables position. If syncing has a lag, credit decisions should err on the conservative side, and the screen should show when the data was last updated.

Inventory visibility: what dealers get to see

Inventory information greatly reduces questions, but more transparency is not always better. First decide which level dealers see:

In stock or out of stock only: the least information, which keeps dealers from rushing stock or bargaining based on actual quantities; suits stock-sensitive items.
Orderable quantity: lets dealers know how much they can order at once, cutting over-quantity orders that get sent back.
Expected arrival date: out-of-stock items show the restock timeline, so dealers can place pre-orders.

Whichever level you show, orderable quantity must subtract quantities already reserved, such as orders placed but not shipped and allocations held for particular customers. Otherwise two dealers both see stock, both order, and the one who ordered second loses out.

With multiple warehouses, you also need to decide whether to show a total or quantities by shipping warehouse. How the inventory itself is managed, such as safety stock, transfers, and stocktakes, is covered more fully in Inventory Management System Development.

Order flow: status design from order to shipment

B2B orders usually do not ship the moment they are submitted; approval, picking, and split shipments come in between. Order statuses should be designed so dealers understand them and internal staff can track them easily.

A common status flow:

Draft: the dealer is still adjusting and can save to submit later.
Submitted: waiting for internal confirmation.
Under review: over the limit, special pricing, or special items that need sales or manager approval.
Confirmed: the order is accepted and moves into picking.
Partially shipped: some items ship first, with out-of-stock items to follow.
Shipped: everything has shipped, with tracking details attached.
Cancelled or returned: with the reason recorded.

Scenarios to handle deliberately:

Quick reorder: B2B customers often reorder the same set of items, and “reorder from last time” saves a great deal of time.
Bulk import: dealers with many items tend to prepare orders in spreadsheets; offer a template import that checks each row during import.
Sales reps ordering on a dealer’s behalf: a rep creates the order during a visit, and the order should show who created it.
Shipping notifications: notify dealers when status changes, by email, LINE (the dominant messaging app in Taiwan), or in-portal messages.

Reconciliation: both sides looking at the same numbers

Month-end reconciliation is the most labor-intensive part of B2B dealings. What the portal can do is have both sides looking at the same record from the start.

On the dealer side, consider providing:

Statements by period, listing every shipment, return, allowance, and payment.
Unpaid items with due dates.
A list of issued invoices with downloads.
Payment reporting, letting dealers upload remittance details for finance to confirm and apply.

The internal side has to handle tracking discrepancies: when a payment a dealer reports does not match what actually arrived, staff need to flag it, assign an owner, and record the outcome. Returns and allowances should be linked to the original order rather than becoming an untraceable adjustment. For issuing e-invoices and handling allowance documents, see the E-Invoice Integration Guide.

ERP integration: first decide who owns each piece of data

Most companies with a dealer network already have an ERP. The portal should not build a second, duplicate set of master records; instead it should define clearly which side is responsible for each type of data.

Use this table to confirm each item with your developer:

Data type	Usual system of record	Sync direction	What to confirm
Product master	ERP	ERP → portal	Who maintains portal-only images and descriptions
Customer master and tiers	ERP	ERP → portal	Which side creates new dealers
Price lists and trade terms	ERP or portal	Depends on rule complexity	Rules can be maintained on one side only
Inventory	ERP	ERP → portal	Sync frequency and how reserved quantities are calculated
Orders	Portal	Portal → ERP	How write failures are retried and reported
Shipments and invoices	ERP	ERP → portal	When status is returned
Receivables and credit	ERP	ERP → portal	Which point in time the credit check relies on

The integration method depends on what the ERP itself offers: one with an open API can sync in real time; one that can only import and export files needs scheduled batches, and you accept some lag. Most important of all is error handling: when an order fails to write to the ERP, it cannot sit silently on the portal with nobody aware; there must be a retry mechanism and a list for manual handling. For integration planning principles, see A Guide to System Integration and API Development; if the ERP itself is still being evaluated, start with ERP Selection for Small and Medium Businesses.

Common mistakes

Converting a B2C store straight into B2B: pricing, credit, and approval all run on exceptions, and every change makes it messier.
No priority order for pricing rules: the same order produces two prices, and the dealer and the salesperson each insist they are right.
Credit definition not agreed with finance: the system says the order can ship, while finance says the dealer was over the limit long ago.
Inventory not net of reservations: two dealers order at once, the second is canceled, and trust takes a hit.
No alerts on integration failures: an order sits on the portal for days and is only discovered when the dealer calls.
Pushing it to every dealer at once: going fully live without a trial means all the problems arrive together.

At heart, a dealer ordering portal takes the trading rules scattered among sales, sales assistants, and finance and organizes them into one system both sides can understand. The clearer the rules, the more useful the portal.
