What it means
Every credit sale creates an account receivable, meaning a promise to pay later rather than cash in hand. Collection is the work of converting that promise into money, and it is a distinct discipline from selling, invoicing or credit approval.
The business consequence is straightforward but easy to underestimate. Profit on paper does not pay wages or suppliers, and a growing company with slow collections can run out of cash while its income statement looks healthy.
Good collection practice is mostly systematic rather than confrontational. Invoices go out the day the work is done, statements are sent on a fixed cycle, a polite reminder lands before the due date, and calls start within days rather than weeks of an account going overdue.
Escalation is where judgement is needed. Handing an account to a collection agency or a solicitor typically recovers less money, since agencies charge a share of what they recover, so most businesses reserve that step for accounts that are genuinely stuck rather than merely late.
Measurement keeps the whole process honest. Days sales outstanding, an ageing analysis that groups unpaid invoices by how overdue they are, and a monthly collection rate together show whether the function is improving or quietly slipping.
In practice
Real-world examples.
Example
A commercial cleaning firm moves from posting invoices monthly to emailing them the morning after each job. Days sales outstanding falls from 47 days to 31 days within a quarter, releasing roughly a month of cash with no change to sales.
Example
A wholesale food supplier discovers that four customers account for 70% of its overdue balances. It puts those accounts on a weekly call schedule and switches two of them to payment on delivery, cutting overdue balances by more than half.
Example
A software company automates dunning, meaning the sequence of reminder messages sent when a card payment fails. Recovering failed renewals that used to be written off adds several thousand dollars of cash a month at almost no cost.
Formula
Calculation
Cash collected in a period = opening receivables + credit sales in the period - closing receivables.
Collection rate = cash collected / (opening receivables + credit sales).
A commercial printing company starts March with $480,000 of unpaid customer invoices and makes $600,000 of credit sales during the month. At the end of March its receivables balance is $420,000.
Cash collected during March = $480,000 + $600,000 - $420,000 = $660,000. The amount available to collect was $480,000 + $600,000 = $1,080,000, so the collection rate is $660,000 / $1,080,000 = 61.1%.
Days sales outstanding for the month is closing receivables divided by credit sales, multiplied by the number of days. That is ($420,000 / $600,000) x 30 = 21 days, meaning the average invoice is being paid three weeks after it is raised.Case study
Seen in the real world.
Brightfield Interiors is a fictional commercial fit-out contractor used here as an illustrative example. It grew revenue by 40% in a year and still needed an overdraft extension every month, which puzzled a board that could see healthy reported profits.
A review found the problem sat entirely in collection. Invoices were raised only when a project manager remembered to sign off the paperwork, sometimes six weeks after the work was finished, and nobody chased an account until it was 60 days overdue.
The company gave one part-time bookkeeper clear ownership of receivables, moved to invoicing on completion of each project stage, and introduced a simple weekly ageing report for the management meeting. Days sales outstanding dropped from 58 days to 34, the overdraft was repaid within five months, and the illustrative lesson was that the cash had always been there, just parked in customers' bank accounts instead of Brightfield's.
Watch out
Common mistakes.
- Treating collection as an accounting chore rather than a commercial activity. The people who know the customer best are usually the ones who can resolve a disputed invoice fastest.
- Waiting until an account is badly overdue before making contact. A friendly call a few days after the due date recovers far more than a formal letter at 90 days.
- Chasing payment without checking the invoice is correct. A large share of late payments are disputes about a wrong purchase order number or a missing reference, not refusals to pay.
Questions
People also ask.
What is a reasonable collection rate?
It depends on payment terms and industry, but the more useful test is whether days sales outstanding is stable or falling relative to the terms you actually offer.
Should we offer early payment discounts?
Only after doing the arithmetic. A 2% discount for paying 20 days early is expensive money, so compare it honestly with the cost of your overdraft.
When should an account go to a collection agency?
Usually once internal contact has failed for 90 to 120 days and the customer has stopped responding, since agency fees mean you will recover materially less than the face value.
