Buying windows on a job-by-job basis from a builders’ merchant is a common starting point, but it’s rarely the most efficient or cost-effective approach for a joiner doing regular window work. A direct trade account with a manufacturer gives you consistent pricing, better technical support, and a relationship that works in your favour when you need something quickly or have a specification question. This article explains what to expect from the process and how to get the most from a trade account once it’s set up.
Why a Trade Account Matters
The difference between buying at trade and buying at retail or through a merchant is significant. Direct manufacturer pricing typically represents a 20–40% reduction against merchant prices for equivalent product, depending on volume. That margin difference goes directly to your bottom line — or gives you room to compete more aggressively on price without sacrificing profit.
Beyond price, a trade account gives you access to a named contact, consistent lead times, and technical support from people who know the product in detail. When a specification question comes up on site, being able to call your supplier’s technical team directly — rather than waiting for a merchant to relay information — saves time and prevents errors.
What Information You’ll Need
Opening a trade account is a straightforward process. Most manufacturers will ask for:
- Business details — your trading name, address, and contact information
- Company structure — sole trader, limited company, or partnership
- UTR or company number — for credit reference purposes; suppliers will typically cross-check this against the public record on Companies House if you trade as a limited company
- Trade references — two or three supplier or customer references for credit accounts
- Estimated monthly spend — helps the supplier determine appropriate credit terms
If you’re new to trading or can’t provide credit references, most suppliers will offer a pro-forma (payment in advance) account as a starting point, with the option to move to credit terms once a trading history is established.
Credit Terms and Payment
Standard trade credit terms are typically 30 days from invoice date, though this varies by supplier. Credit limits are set based on your credit history and anticipated spend. Understanding and managing your credit terms is important — particularly when you are ordering product for large jobs where material cost may be significant against your credit limit.

Some manufacturers offer early payment discounts — for example, 2% discount for payment within 7 days. On larger orders, this can be worth taking if cash flow allows. Always read the terms carefully and ensure you understand what happens to your account if a payment is delayed. Suppliers signed up to the Prompt Payment Code commit to clear, fair payment terms, which is worth checking if payment reliability matters to your cash flow.
Pricing Structure and Volume Discounts
Trade pricing with a direct manufacturer is typically structured on volume bands — the more you buy over a period, the better the pricing tier you qualify for. When you open a new account, ask your supplier to explain the pricing structure clearly:
- What is the standard trade price list?
- Are there volume thresholds that trigger better pricing, and what are they?
- Are prices fixed or subject to periodic review?
- How are pricing increases communicated?
Technical Support and Aftercare
One of the most underused benefits of a direct trade account is access to technical support. A good manufacturer will have staff who can answer specification questions, review measurements before they go into production, and advise on non-standard situations. Make use of this — it’s included in your account and prevents costly errors.
Clarify the warranty and aftercare process when you open your account. Understand exactly what is covered, for how long, and how to make a claim. A manufacturer who handles warranty claims directly — rather than redirecting you to the profile or hardware supplier — is far easier to work with when something goes wrong.
Getting the Most from Your Account
- Build a relationship with your named contact — they can often expedite orders or flag potential issues before they become problems
- Always confirm orders in writing and review the order acknowledgement before production begins
- Consolidate orders where possible — fewer, larger orders reduce delivery complexity and can help you hit volume pricing thresholds
- Ask for technical documentation proactively — U-value certificates, energy ratings, and Declarations of Performance should be available on request and are worth keeping on file
