• Practical steps to align your creditor days with agreed payment terms and sector norms.

Creditor days tells you the average number of days your business takes to pay its trade suppliers - calculated as (Trade Creditors ÷ Cost of Sales) × 365. For UK trade businesses, a typical figure runs anywhere from 30 days at a small sole-trader electrical firm to 70 days at a main contractor, and the difference is not a matter of discipline. It reflects where each business sits in the payment chain. A 55-day creditor days figure is defensible for a general contractor whose clients pay on 60-day applications. The same number at a promotional merchandise distributor paying suppliers on 30-day terms means every invoice is running late.

The Formula and a Worked Example

The formula has two common versions. The standard version uses cost of sales as the denominator:

Creditor Days = (Trade Creditors ÷ Cost of Sales) × 365

A technically more accurate version uses purchases rather than cost of sales, because cost of sales includes direct labour and production overheads that do not sit in your trade creditor balance. In practice, purchases are not always broken out separately in management accounts, so cost of sales is the figure most businesses use.

Both versions give you the same directional read. Pick one and use it consistently, because the benchmark matters less than the trend.

Worked example (illustrative):

An electrical contractor has £68,000 in trade creditors at year end and annual cost of sales of £490,000.

Creditor Days = (68,000 ÷ 490,000) × 365 = 50.7 days

That figure means the business is taking, on average, just over 50 days to settle its supplier invoices. Whether that is healthy depends on what terms it has agreed with those suppliers - and what sector benchmarks say for a business of its type.

Benchmark Ranges for UK Trade Businesses

Benchmarks vary by sector. The ranges below reflect typical creditor days for established UK SMEs, drawn from UK accounting analysis and Companies House data:

Wholesale and distribution: 35-50 days. Distributors - including promotional merchandise businesses - tend to run moderate creditor days because supplier relationships depend on prompt payment for access to stock, samples, and priority allocation. Much of the supply base operates on 30-day terms, so a distributor running 50+ days is likely paying late.

Construction (main and general contractors): 50-70 days. Main contractors routinely negotiate extended payment terms with sub-contractors and material suppliers. Payment applications on 30- to 60-day cycles, combined with the standard industry practice of stage invoicing, mean higher creditor days are structurally normal. A figure in the 55-65 day range is common for a main contractor without indicating cash pressure.

Specialist trade contractors (electrical, plumbing, heating, renewables): 35-55 days. Specialist sub-contractors occupy a different position. They typically pay material suppliers on 30-day terms while waiting 45-60 days for payment from the main contractor above them. That asymmetry is the core working capital challenge for trade businesses - their creditor days often cannot be extended without damaging supplier terms, even though their debtor days are long.

Joinery and fit-out: 40-60 days. Joinery and interior fit-out businesses often carry both material and sub-contractor creditors, with project payment tied to practical completion milestones. Creditor days in the 45-55 range are common where projects run 8-16 weeks.

Promotional merchandise distributors: 30-45 days. Most decorator and blank goods suppliers work on 30-day terms, and distributors who consistently exceed that figure may find themselves placed on pro-forma payment or stripped of preferred supplier access. A figure above 50 days in this sector is a warning.

Renewables installers (solar, heat pumps, EV charging): 35-55 days. Equipment procurement on 30-day supplier terms, combined with stage-payment schedules from customers, creates a structural cash gap. Creditor days in the 40-50 range are common; above 60 days often indicates the business is waiting on a grant payment or customer sign-off before it can settle equipment suppliers.

Why Your Position in the Payment Chain Is the Right Benchmark

Two businesses can have identical creditor days figures and opposite financial health readings. A main contractor at 60 days, collecting on 60-day payment applications and paying sub-contractors on the same cycle, is running a tight but balanced operation. A specialist electrical sub-contractor at 60 days, being paid by the main contractor on 60-day terms but obliged to pay material suppliers on 30-day terms, is structurally late to suppliers on every single invoice.

The test is not the absolute figure. It is the relationship between three numbers:

Agreed payment terms with your suppliers. If your terms say 30 days and your creditor days are 50, you are paying late regardless of what the sector average says.

Your own debtor days. A business collecting from customers in 45 days and paying suppliers in 50 days has a structural cash gap of 5 days - manageable. A business collecting in 75 days and paying in 50 days is funding 25 days of its own working capital from cash reserves or a credit facility. That gap compounds as revenue grows. See aged debt for how to track the shape of what you are owed.

The consistency of both figures over time. A creditor days figure that jumps from 45 to 65 in a single quarter is a more significant signal than a stable 65-day figure. The sudden rise - especially if debtor days have not moved - usually means the business has hit a cash constraint and is stretching suppliers to cover it.

What Your Number Is Telling You

Under 30 days: You are paying suppliers faster than necessary. In most cases this is not a problem - it may reflect good supplier relationships or simple payment processes - but if your own debtor days are 45-60 days, you are effectively funding your customers' extended terms with your own cash. Review whether you can take full use of agreed terms without paying early.

30-45 days: Normal for most UK trade businesses on standard 30-day supplier terms. Healthy if your debtor days are below 50 and your suppliers are on 30-day terms. Investigate if your debtor days are above 60, because the gap between what you collect and what you pay is being funded from somewhere.

45-60 days: Acceptable for construction and larger trade businesses with extended terms in their supply contracts. A warning for distributors and specialist sub-contractors who should be on 30-day terms. Check your agreed terms before concluding the figure is fine.

Over 60 days: In most UK trade business contexts, this warrants investigation. It may mean you have successfully negotiated 60-day terms with suppliers - in which case it is intentional. More often it means invoices are being paid late because cash is not available on the due date. Lenders and credit agencies treat a consistent creditor days figure above 60 days as a risk indicator.

Rising trend year-on-year: This is the most important diagnostic signal. A creditor days figure that increases each year, even if the absolute number looks reasonable, suggests the business is progressively more reliant on supplier credit to fund its day-to-day operations. That pattern is visible to credit reference agencies, insurers, and suppliers who run their own credit checks.

Managing Creditor Days Strategically

Use your full agreed terms. If a supplier offers 30-day terms, paying on day 28 rather than day 12 is a cash management decision, not a payment performance failure. Many small trade businesses pay early by default because their payment process runs faster than their cash planning. Aligning payment timing to due dates rather than invoice receipt dates frees cash without touching supplier relationships.

Negotiate terms before you need them. Extended payment terms - moving from 30 to 45 or 60 days - are far easier to secure from a supplier when your account is in good standing and you are paying on time. Businesses that only ask for extended terms when they are already under pressure typically do not get them.

Centralise and schedule payments. Running one or two payment runs per week gives better visibility of what is due and prevents both early payment (cash leak) and late payment (relationship damage). A simple schedule - reviewed weekly against the cash position - is more reliable than processing invoices as they arrive.

Separate deliberate extension from inability to pay. If your creditor days are rising because you have intentionally taken fuller advantage of agreed terms, that is working capital management. If they are rising because cash is not available on payment due dates, that is a warning sign that needs addressing before it reaches suppliers, credit agencies, or your bank. The distinction matters.

Connect creditor days to your invoice process. The fastest single lever on your creditor days is reducing your own debtor days - collecting from customers faster. Trade businesses that issue invoices promptly, follow up on overdue accounts within 7 days, and match payment applications to project milestones consistently outperform those that invoice late and chase reluctantly.

What Good Looks Like

A trade business with healthy creditor days management typically shows three things in combination: a creditor days figure within or close to agreed supplier terms; a debtor days figure that is shorter than creditor days or at worst equal to it; and a creditor days trend that is stable or narrowing year-on-year.

Achieving that combination is not primarily about payment discipline. It is about invoice accuracy, invoice timing, and follow-up on overdue customer accounts. A business that invoices promptly, captures every billable item, and collects within its agreed customer terms almost always finds that its supplier payment position takes care of itself - because the cash arrives before the due dates fall.

Zigaflow's invoices feature gives trade businesses a structured way to track when invoices go out, monitor what is outstanding, and identify where collection is lagging - so the connection between customer payment timing and supplier payment capacity stays visible rather than emerging as a surprise at month end.
