The job finished on a Tuesday. The ticket made it back to the office on Friday. The invoice went out the following Wednesday, on net 30 terms. Before a single dollar comes in, the company has paid for that job’s fuel, wages and equipment time for the better part of six weeks.
Nobody decided to wait that long. It happened one small delay at a time: a ticket left in a truck, a rate someone had to look up, a question for the foreman who was out on another job.
This article looks at how invoicing delays affect cash flow, what the research says about late payment for small businesses in Canada and the US, and the practical steps that shorten the time between finishing a job and getting paid.
Cash flow trouble is common, and receivables are a big part of it
If cash feels tight even in a busy month, you are in good company.
In the Federal Reserve Banks’ 2024 Small Business Credit Survey, which collected 7,653 responses from US employer firms, 51% said uneven cash flows had been a financial challenge in the prior 12 months. The survey counts collecting on receivables as part of that category.1
The picture in Canada is similar. Atradius, a trade credit insurer, reported in its 2026 survey of Canadian businesses that late payment affects seven in ten companies, and that overdue invoices make up an average of 25% of business-to-business receivables. Nearly two thirds of those invoices are due within one month of invoicing. The most common reason for delays was the customer’s own cash flow, named by roughly half of firms.2
And in a 2025 late payments survey of 2,487 US small businesses with up to 100 employees, 56% said they were owed money on unpaid invoices, an average of $17,500 per business. Firms with more late payments were more likely to report cash flow problems: 50% compared with 34% for firms with fewer.3
Much of this is out of your hands. You cannot fix a customer’s cash crunch. But one part of the timeline is entirely yours: how long it takes to send the invoice in the first place.
The clock starts when the invoice goes out
Payment terms count from the invoice date, not from the day the work was done. So every day between “job complete” and “invoice sent” gets added straight onto the time it takes to be paid. Net 30 is really net 30 plus however long your office takes.
Here is an illustrative example of the same job run two ways. The customer pays ten days late in both cases.
| Stage | Slow process | Same-day process |
|---|---|---|
| Job finished | Day 0 | Day 0 |
| Ticket reaches the office | Day 3 | Day 0 |
| Invoice sent | Day 10 | Day 1 |
| Due date on net 30 | Day 40 | Day 31 |
| Paid, ten days late | Day 50 | Day 41 |
Same customer, same terms, same late habit. The only difference is nine days of paperwork, and it shows up in the bank account every single time.
The Business Development Bank of Canada puts the advice plainly: send the bill as soon as you have finished the job, because putting off billing is a bad habit and “you may forget to bill altogether.”4
Where the days go
In most service companies, the delay is not one big holdup. It is a handful of small ones:
- The ticket travels. A paper ticket rides in a truck until someone drops it off, sometimes days later.
- The details get retyped. Hours, equipment, materials and rates are copied from the ticket into a spreadsheet, then into the invoice.
- Questions go back to the field. A missing hour or an unclear charge means a call to the crew, then waiting for a callback.
- Invoices wait for month end. Many companies batch billing, so a job finished on the 3rd is invoiced on the 31st.
- Approval sits with one person. The owner checks every invoice, and the owner is busy.
None of these are failures of effort. They are what happens when the job details live in too many places.
Measuring it: days sales outstanding
The standard way to measure how quickly you turn work into cash is days sales outstanding, or DSO. It is the average number of days between making a sale and collecting the money.
The usual formula is accounts receivable divided by revenue for a period, multiplied by the number of days in that period. If you have $180,000 in receivables and billed $450,000 over the last 90 days, your DSO is 180,000 divided by 450,000, times 90, which is 36 days.
For a benchmark, APQC’s accounts receivable survey of 5,204 participants across industries found that top performers collected in 30 days or less on average, the median was about 36 days, and bottom performers took 48 days or longer.5 Treat that as a rough guide rather than a target. A company that bills on net 45 will naturally carry a higher DSO than one that collects on the spot.
For a service company, a second number is just as useful: days from ticket to invoice. It is not a textbook metric, but it is the part of DSO you control completely. Take ten recent jobs, compare the date each one was finished with the date it was invoiced, and average the gap. If that number is more than two or three days, there is cash sitting in your process.
What slow invoicing really costs
Money you have earned but cannot use
A simple way to see the cost: divide your monthly billing by 30 to get roughly one day of invoicing. If you bill $100,000 a month, that is about $3,300 a day. If your invoices go out ten days after the work, about $33,000 of earned revenue is always sitting unbilled. That is money you have already paid wages and fuel for, and it is often covered by a line of credit that charges interest.
Disputes get harder to settle
A customer questioning an invoice the week after the job can usually be sorted out with a quick call. Three weeks later, the site supervisor has moved on, nobody remembers whether the truck waited two hours or three, and the dispute drags. The longer the gap, the weaker your evidence and the slower the payment.
Charges fall through the cracks
Extra hours, a second load, materials picked up on the way: these are easy to miss when the invoice is built from memory or a smudged ticket days later. Each one is small. Over a year they add up.
Longer waits make every problem worse
The same survey found that 60% of businesses with longer payment terms reported cash flow problems, compared with 40% of those whose terms were immediate.3 Slow invoicing works like longer terms that you have given your customer for free.
Six ways to shorten ticket to cash
- Close the ticket in the field. Hours, notes and photos should be recorded when the work is done, by the person who did it, not reconstructed later.
- Build the invoice from the ticket. If the office is retyping hours and rates, every invoice is a chance for a typo and a delay.
- Invoice when the job closes. Unless a customer has asked for monthly billing, send the invoice the same day or the next. See how same-day invoicing works in practice.
- Make it easy to pay. A link to pay by card removes the “we’ll cut a cheque next run” step for customers who are happy to pay now. Atradius found Canadian firms were more likely than their North American peers to respond to payment risk by automating reminders and moving to digital payments.2
- Follow up on a schedule. Most late invoices are not refused, they are forgotten. A polite reminder on day one, day seven and day fourteen past due gets more paid than an awkward phone call at day 60.
- Watch two numbers. Check DSO once a month and ticket-to-invoice days once a week. If either creeps up, you will see it before the bank balance does.
Where Dispatch fits
Dispatch was built around this exact path, from the ticket to the payment. Crews open a link on their phone to update the job status and add photos and notes, so the ticket is complete when the work is. The office builds an invoice from one or more completed tickets, with each client’s rates already applied, and sends it by email with a PDF and a link to pay by card. If it goes past due, reminders go out on the schedule you set, and you can see more on chasing overdue invoices and payments and reminders.
Dispatch is not accounting software, and it does not try to replace your bookkeeper. It handles the part before the books: getting the job done, the ticket closed and the invoice out the same day. If that gap is where your cash is sitting, book a demo and we will walk through it with your own jobs.
