The Quote You Sent Before the Supplier Prices Came Back
Sending a customer quote before confirming supplier prices is standard practice in most trade businesses. When input costs are rising 8.7% a year, the gap between what you quoted and what you will actually pay can eliminate a job's margin entirely.
You price a job on a Tuesday. Materials are costed from the price list you've been working from for the last few months - it's close enough, it's always been close enough. The quote goes out on Wednesday. The customer comes back three weeks later to say they want to go ahead. You place the order with the supplier and the price has moved. Not by a rounding error. By enough to turn a 20% margin into 8%. The job is live. You can't reprice it now.
This isn't a rare edge case. It's a structural problem that affects most trade, contracting, and supply businesses that quote jobs without first confirming supplier prices. And in a period when UK producer input prices rose 8.7% in the year to May 2026, according to the Office for National Statistics, the gap between the price you quoted and the price you'll actually pay for materials is no longer a manageable variable. It's a margin risk you are carrying on every single job.
The Time Between Quoting and Ordering Is Where the Risk Lives
A customer quote has two prices in it: the price the customer sees and the cost you expect to pay for goods or materials to fulfil it. The customer price is locked the moment the quote is accepted. The supplier cost, in most businesses, is not confirmed at the same time.
The sequence usually looks like this. You quote based on your best estimate of material costs, using last week's price list, a supplier conversation from last month, or rates you know from previous similar jobs. The customer takes time to decide. In some industries - fit-out, AV integration, promotional merchandise - that decision can take two to six weeks. By the time the job is live and you go to order, supplier prices may have moved. Your quoted margin was calculated on costs that no longer exist.
This is not a problem caused by carelessness. It's caused by the way most quoting processes are structured: customer quote first, supplier verification later. The quote gets all the attention because it's the thing you send. The supplier cost check gets squeezed because it feels like it can wait.
Quote validity windows
Many businesses set quote validity periods of 30 days, but don't apply the same discipline to the supplier price data inside the quote. If your quote is valid for 30 days but your supplier prices are based on a conversation from six weeks ago, you are carrying unconfirmed cost risk from the moment the quote leaves your desk.
What the Numbers Look Like When Prices Move
A case published by RapidQS UK in 2026 documents a contractor who priced timber for a residential project at £380 per cubic metre, based on a quote received the previous year. By the time the materials were ordered, the market rate had risen to £490 per cubic metre. On the scope of the project, that single movement added more than £22,000 to the materials bill - before any quantity errors were counted. The total project overrun reached £40,000 on a £250,000 contract.
Timber prices rose 15% in 2026 compared to 2025 in the UK, driven by supply chain disruption. Other materials moved too. The same case notes that industry surveys consistently show between 30 and 40% of SME contractors have experienced a project that delivered a loss or near-zero margin because of pricing errors - with outdated material rates cited as one of the most common root causes.
The practical recommendation that emerged from the case was direct: get fresh supplier quotes from at least two suppliers before submitting any tender, and do not price from historic rates more than eight weeks old.
Most businesses know this. The problem is building a reliable process to do it.
Why Most Businesses Don't Confirm Supplier Prices Before They Quote
There are three reasons this step gets skipped, and none of them are unreasonable.
The first is speed. Customers expect quotes quickly. Taking an extra two or three days to get supplier prices confirmed before sending a customer quote can feel like a competitive disadvantage, especially if a competitor quotes within 24 hours. Speed wins jobs. That pressure is real.
The second is friction. Contacting two or three suppliers per quote, by phone or email, waiting for responses, chasing when they don't arrive, comparing what comes back - this takes time that most quoting processes don't formally allocate. When a business is busy, this step gets compressed into an estimate based on memory and experience.
The third is assumption. In stable cost environments, pricing from historic rates works often enough that the habit holds. The few jobs where it goes wrong tend to get absorbed rather than analysed, because the gap between what was expected and what was paid is difficult to pin to a specific quoting decision weeks or months later.
All three of these reasons become more costly as input price volatility increases. When supplier prices move by single-digit percentages over a full year, the risk of using last month's rates is low. When UK producer input prices move by 8.7% in twelve months, with significant month-to-month variation, the risk of using last month's rates is genuinely material.
The assumption gap
If a job wins quickly - within a few days of the quote - supplier prices are unlikely to have moved significantly. The risk concentrates on longer decision cycles. A job that takes three to five weeks to confirm carries the most exposure, because that is also exactly the kind of job where the order value is high enough for price movement to matter.
What a Formal Supplier Quote Request Process Actually Changes
Confirming supplier prices before quoting doesn't have to mean sending individual emails and waiting. A structured request for quotation process sets out exactly what you need, sends it to the right suppliers, and tracks the responses.
The difference between an ad hoc email to a supplier and a formal RFQ is traceability. An email conversation confirms a price informally, and when the job finally goes to order four weeks later, there is often no clear record of what was agreed, whether the price is still valid, or who to call if it has changed. A logged RFQ creates a reference point. You can see which suppliers responded, what they quoted, what the validity period is, and whether you need to reconfirm before placing the order.
For businesses quoting multiple jobs simultaneously - or working with several suppliers per job - Zigaflow's RFQ feature brings that process into a single workflow. RFQs go out directly to suppliers from within the platform. Responses come back against the same record. When you're ready to compare, the quotes sit side by side rather than across a thread of emails. Once you've chosen a supplier, the confirmed cost flows directly into the job record, so the margin on the customer quote is calculated against a price you've actually confirmed, not one you're remembering.
The habit to build is simple: don't send a customer quote until you've confirmed the supplier prices it's built on - or until you've formally flagged which costs are estimated and what tolerance you're working with. A job costing approach that separates confirmed costs from estimates makes that transparency possible at the quoting stage, before it becomes an unpleasant surprise during delivery.
Three weeks is a long time for a supplier price to hold. Worth checking before you commit the customer to a number that depends on it.
