The short answer
Set up three automatic reminders on every invoice: a friendly nudge a few days before the due date, a polite one the day it's due, and a firmer one about a week after if it's still unpaid. Write them once, let them send on schedule, and make sure they stop the instant the invoice is marked paid. That way the invoice chases itself and you never have to send the awkward "just following up" email again.
The rest of this is the timing, the exact wording, and how to keep a reminder from firing at a client who already paid.
Why automatic reminders beat chasing by hand
The real reason freelancers get paid late has less to do with clients and more to do with the follow-up that never gets sent. Writing "hey, just checking on that invoice" feels like begging, so it sits in the drafts folder while the payment sits unpaid. Weeks pass. The money is technically owed and practically stuck.
An automated reminder removes the feeling from the task. It goes out on a schedule you set when you weren't emotionally invested in the outcome, so there's no moment where you have to decide whether to be pushy today. The client gets a clear, calm nudge. You get paid without spending willpower on it.
There's a second benefit that matters more than it looks. A reminder that fires on time, every time, trains clients to treat your invoices as real deadlines. When follow-ups are random, clients learn that late has no consequence. When they're reliable, paying on time becomes the path of least resistance.
When should you send payment reminders?
A three-touch schedule covers almost every freelance invoice without tipping into nagging:
- Three days before the due date. A soft heads-up while the invoice is still current. This one prevents most late payments outright, because it lands while the client still has time to act and no awkwardness has built up yet.
- On the due date. A short, neutral note that the payment is due today. No accusation, because nothing is late yet.
- Five to seven days after the due date. The first genuinely firm reminder, sent once the invoice is actually overdue. This is the one most freelancers dread writing, which is exactly why it should be automated.
For a client who's gone quiet past that, a fourth reminder at the two-week mark is reasonable before you switch to a direct personal message. Beyond three or four automated touches, more emails stop helping and start reading as noise.
What should a payment reminder say?
Keep every reminder short, specific, and free of apology. Name the invoice number, the amount, and the date. Give them the way to pay in the same message. The tone stays warm right up until the invoice is genuinely overdue, then it gets clear without getting angry.
A before-due nudge can be as simple as this:
Hi [name], quick heads-up that invoice #1042 for $1,200 is due on [date]. You can pay it here: [link]. Thanks!
An overdue reminder tightens up without turning hostile:
Hi [name], invoice #1042 for $1,200 was due on [date] and is now a week overdue. Could you let me know when I can expect payment? You can pay it directly here: [link]. Thanks.
Two things make these work. First, the payment link is right there, so paying is a thirty-second action instead of a task the client files away for later. Second, you never apologize for asking to be paid for work you delivered. "Sorry to bother you" invites the client to treat the invoice as optional. A plain, factual reminder does the opposite.
How do you stop reminders once a client pays?
This is the part that scares people off automation, and it's the part that matters most. The nightmare is a reminder firing at a client who paid last week, making you look disorganized right after they did the right thing.
The fix is simple: reminders have to be tied to the invoice's status. A reminder that only watches the calendar will eventually fire at someone who already paid. The moment an invoice is marked paid, every future reminder on it has to cancel automatically. If your system can't guarantee that, automation is riskier than chasing by hand, because one wrongly-sent reminder costs more goodwill than a late payment does.
So the real test of any reminder setup is the off switch. It should send the awkward follow-ups for you and go completely silent the second the money arrives. That combination, reliable sending plus a reliable stop, is what makes automation safe to trust.
Where a reminder fits in getting paid
A reminder is the safety net for a payment that's already running late. The earlier stages of getting paid on time are set before the invoice ever goes out: asking for a deposit so the client has skin in the game from day one, and structuring milestone payments so money arrives as the work does. Get those right and the reminder often never has to fire. Automate the reminder anyway, for the invoices that still slip.
Setting reminders up in Loot
This is the exact problem Loot's automated reminders were built around. You write your reminder schedule once, and every invoice you send carries it, so the before-due nudge, the due-date note, and the overdue follow-up all go out on their own. The moment you mark an invoice paid, its reminders stop. No double-ask, no chasing a client who already settled up.
Free accounts get one automated reminder slot, which is enough to cover the overdue follow-up most people dread sending. Pro unlocks unlimited slots with the message on each one editable, so you can run the full before-due, due-date, and overdue sequence and word each touch yourself.
And because Loot settles payments through Stripe Connect, the money from a paid invoice lands straight in your own account, never a platform's holding tank. The reminder does the chasing; the payment goes directly to you.

Frequently asked questions
How many payment reminders should I send? Three covers most invoices: one before the due date, one on the due date, and one about a week after if it's still unpaid. A fourth at two weeks is reasonable before you switch to a personal message. More than that reads as nagging and stops working.
When should the first payment reminder go out? A few days before the due date, while the invoice is still current. A before-due nudge prevents more late payments than any after-the-fact reminder, because it lands before anything is overdue or awkward.
What do you write in a polite payment reminder? Name the invoice number, the amount, and the due date, and include the payment link. Keep it short and skip the apology. Stay warm before the due date and get clear, without getting angry, once it's genuinely overdue.
Can automatic reminders stop once an invoice is paid? They should, and this is the most important feature to check. Good reminder automation ties sending to the invoice status, so every future reminder cancels the instant the invoice is marked paid. In Loot, reminders stop automatically when payment lands.
Is it unprofessional to send automated payment reminders? No. Reliable, well-worded reminders read as organized. What actually looks unprofessional is inconsistent chasing, or a reminder sent to someone who already paid. Consistent timing and a clean off switch are what keep automation looking professional.
