What are late payments really costing you?
Most owners feel late payments as a hassle rather than a number. This turns the hassle into a yearly figure, so you can see which part is worth fixing first.
Late payments cost you four ways: cash stuck in unpaid invoices, interest on the credit covering that gap, hours spent chasing, and invoices written off. Add the four and you have the yearly cost of getting paid late.
The math
How this works
How much do late payments cost a small business?
The cost shows up in four places. Money sitting in overdue invoices is money you cannot spend, so you cover payroll and supplies with a line of credit or a card and pay interest on it. Chasing payments takes real hours that could have gone to billable work. A share of late invoices never gets collected at all and eventually comes off the books. Put your own numbers into the calculator above and you get a single yearly figure for all four, which makes it much easier to judge what a fix is worth.
Why do customers pay invoices late?
Most late payments are not bad faith. The usual causes are an invoice that went to the wrong person, a missing purchase order or job number, terms the customer never agreed to, or a payment method that is inconvenient for whoever signs the check. Larger customers often run a check cycle on fixed days of the month, so an invoice that arrives a day after the cutoff waits weeks. Before you label a customer a slow payer, find out which of these is actually happening, because each one has a different fix.
How do I get customers to pay faster?
Start with the invoice itself: send it the day the work is finished, address it to the person who approves payment, and put the due date, the amount and the accepted payment methods where they cannot be missed. Agree the terms in writing before the work starts so the due date is never a surprise. Offer a way to pay that takes one click rather than a check and an envelope. Then set a routine, such as a reminder a few days before the due date and another the day after, so following up is a process instead of an awkward phone call. For customers who are late every time, consider asking for a deposit before the next job.
Questions people ask
What does Net 30 mean?
Net 30 means the full amount is due 30 days after the invoice date. Net 15 and Net 60 work the same way with a different window. The clock starts on the invoice date rather than the day the work was done, which is one good reason to invoice the same day you finish.
Can I charge a late fee on overdue invoices?
Many businesses do, but it only works when the fee is spelled out in the agreement and on the invoice before the work starts. What you can charge and how it is calculated depend on your contract and the rules where you operate, so confirm the details with your own advisor. A fee is also a conversation with a customer, so decide in advance when you would actually apply one.
When should I write an invoice off?
There is no single rule. Most owners write an invoice off once reminders, a phone call and a formal demand have all gone unanswered and the amount is too small to pursue further. Your bookkeeper records it as a bad debt so the books show what you actually collected. Watching that percentage year over year tells you whether your intake and deposit practices need tightening.
Is offering an early-payment discount worth it?
Sometimes. A discount is a real cost, so weigh it against what the delay costs you in financing and chasing time. If a 2 percent discount gets you paid 3 weeks sooner and the alternative is drawing on a line of credit, it can be the cheaper path. The early-payment discount calculator runs that comparison on your own numbers.
