One of the most frustrating things in any freelancer’s career is dealing with the inevitable late payments from clients who just can’t seem to pay their bills on time. Is it intentional, or simple forgetfulness? Most importantly, what can you do to make sure your clients cough up the dough when they’re supposed to?
As freelancers ourselves, we’ve often had to deal with the very same issue. Through our work with our online invoicing app Invotrak we’ve found five simple strategies that statistically seem to work.
Invoice Amounts
First, we took a look at the correlation between the time it took to pay an invoice and the amount due. Is it possible that invoices for larger amounts regularly took longer to be paid? Intuitively, it seems so, and the data backs it up:

Our research shows that, on average, invoices for smaller amounts (less than $500), tended to be paid within about 33 days. As the invoice amount went up, however, so did the time it took to receive payment. The lesson here is to invoice early, and invoice often.
Terms
Every invoice you issue has a due date attached to it. One seemingly obvious fact: invoices are more likely to be paid on time when their terms are longer. But there’s more to it than that. For instance, take a look at the following graph:

If you’re insistent on shorter payment times, you’re in for a world of disappointment in the 14-day and shorter time periods. Our research has shown that over 75% of invoices issued with a 10-day payment window become overdue. Invoices with a term of 45 days are far more likely to be paid on time then invoices with 30-day due dates.
There’s a number of possible reasons for this. For instance, clients may be accustomed to getting 30-day terms and know they can often push these terms by a few days (and encountering 45-days throws them off). Or, perhaps clients pay all their bills in batches, regardless of when the invoice is due.
Whatever the reason, if you’re interested in getting paid on time and avoiding friction with your clients, go with the 45-day term instead of the typical 30.
Invoice Reminders
Another strategy to getting paid on time is to send out reminder notices to clients about upcoming invoices. These reminders, often automated and sent several days before the invoice is due, are usually encouraged by experts. Do they actually work though? Let’s take a look at the average days to pay an invoice for each of four popular invoice terms:

According to our research, not really. For instance, overdue invoices issued with 30-day payment terms averaged payment 6 days late. Invoices with automated reminders sent out did … almost identically.
This lends itself to the conclusion that clients aren’t typically forgetful of invoices and need reminding; instead, they are planning to pay the invoice on their own schedule.
Of course, you need to judge for yourself. If you have a client that seems to be forgetful of invoices, (or needs a subtle reminder that you’re serious about due dates) you should send those reminders. Simple, automated reminders can be a great way to nudge clients without introducing friction.
Secrets to Getting Paid On Time
So what’s the secret to ensuring you get paid on time? Here are the key lessons:
- The norm for most invoices is 30 days. Clients tend to expect these terms and are likely to structure their own finances around it. It’s not unlikely for clients to send out payments for many vendors at the same time.
- If you’re worried about tension in the relationship, consider using 45-day terms instead of 30. It’s more likely clients will pay within those 45 days, creating less cause for arguments or awkward notices.
- Invoices for smaller amounts were more likely to be paid faster than invoices for larger amounts.
- Invoice terms of less than 14 days are routinely late.
- Sending out reminders several days before an invoice is due can be helpful in some situations but didn’t have a noticeable impact in our research.
Ultimately, you’re the judge of your own situation. You know your clients, their habits, and how likely they are to accept certain terms. If you have the flexibility, try to invoice for smaller amounts on a regular basis. What strategies have you used to get paid on time?
