How to reduce DSO and get paid faster
Updated 2026-06-18
DSO (Days Sales Outstanding) measures how long, on average, it takes to collect a credit sale. The higher it is, the longer your cash is tied up and the tighter your finances. The good news: DSO is largely something you can actively manage. Work out your current number with the DSO calculator, then improve it with the methods below.
Why DSO matters
Profit is on paper; cash is what you can spend. Two companies with the same revenue but different DSO are not equal — the one with the lower DSO always has more usable cash on hand to buy stock, pay wages, or seize an opportunity. Companies with a high DSO often have “profit but no money to use”.
Seven ways to lower DSO
1. Invoice fast and accurately
Invoice as soon as you deliver — don’t save it for month-end. An error can give the client a legitimate reason to stall a whole round. See what to include on an invoice.
2. Make payment terms clear
Write a specific due date rather than “within 30 days”; agree a late-payment rate and fee up front (see are late fees legal), so paying on time becomes the default.
3. Remind before the due date
Don’t wait until it’s overdue. A friendly pre-reminder a few days before the due date heads off a lot of “simply forgot” lateness.
4. Chase on a fixed cadence
Build a polite-to-firm reminder ladder and stick to it. For the cadence and scripts, see how to ask for payment politely and the reminder templates.
5. Reduce payment friction
The easier it is to pay, the faster you’re paid. Put your account or a payment link right on the invoice and support several methods.
6. Offer a small early-payment incentive
When cash cycles matter, offer a small early-payment discount (e.g. “2% off if paid within 10 days”) — trading a little margin for faster cash.
7. Screen credit before you start
For new, larger clients, check their payment reputation. Avoiding trouble before the work beats chasing afterwards.
Let collection speed up on its own
What all of these have in common is being consistent, timely and on a cadence — exactly what’s hardest to keep up by hand. Duefy tracks every invoice, chases on schedule and escalates overdue ones, systematically bringing your DSO down.
