Quick answer: Payment reminder automation means your accounting system sends invoices on time and follows up overdue ones on a schedule, without anyone typing emails. Most small businesses can do this inside QuickBooks Online, Xero or FreshBooks, add an online payment link (Stripe, PayPal or GoCardless), and use a tool like Chaser or Zapier for extra steps. Set a polite reminder sequence, keep a human for difficult cases, and review the results monthly.
Chasing invoices is one of the least loved jobs in any small business. It is awkward, it is easy to forget when work is busy, and the cost of forgetting is cash flow. Automating it takes the awkwardness and the forgetting out of the process.
This guide explains how to set it up step by step.
Why automate invoicing and reminders
- Invoices go out on time. A delayed invoice is a delayed payment.
- Reminders are consistent. Every customer gets the same polite follow-up, on schedule.
- Staff time is freed. No more lists of who to email this week.
- Relationships stay friendly. An automatic reminder feels routine, not personal.
- Better visibility. You can see at a glance who has been reminded and who has paid.
Step 1: Get invoicing into one system
Automation only works if invoices live in one place. If you invoice from Word templates and track payments in a spreadsheet, move to an accounting tool first.
Common choices for small businesses:
- QuickBooks Online: invoicing, reminders, payments and bookkeeping
- Xero: invoicing with automatic reminders and many add-ons
- FreshBooks: popular with freelancers and service businesses
- Zoho Invoice / Zoho Books: part of a wider suite
Each can store customer details, invoice templates, payment terms and tax settings.
Step 2: Automate the invoice itself
Recurring invoices
For retainers, subscriptions or regular services, set up recurring invoices that are created and sent automatically on a fixed date.
Invoices triggered by events
For one-off work, invoices can be created when something happens elsewhere:
- An order is completed in your online shop
- A project is marked done in your project tool
- A deal is marked won in your CRM
- A timesheet is approved
Native integrations or tools like Zapier can connect these events to your accounting software. If your systems need a deeper connection, an API integration can create invoices directly with the right line items.
Clear payment terms
Put the due date, payment methods and late payment terms on every invoice. “Due in 14 days” is clearer than “Net 14” for many customers.
Step 3: Add an online payment option
The easiest invoice to pay is one with a “Pay now” button. Connect a payment provider:
- Stripe: card payments, works with many accounting tools
- PayPal: familiar to customers, invoicing built in
- GoCardless: direct debit for recurring payments (strong in the UK and Europe)
- The accounting software’s own payments feature, where available
Payments made through the link are usually marked as paid automatically, which also stops reminders going out to people who have already paid.
Step 4: Build a polite reminder sequence
A simple sequence works for most businesses:
| When | Message tone |
|---|---|
| 3 days before due | Friendly heads-up, invoice attached, pay link |
| On due date | Short reminder that payment is due today |
| 7 days overdue | Polite note, ask if anything is wrong with the invoice |
| 14 days overdue | Firmer reminder, restate terms |
| 30 days overdue | Final automated notice, then hand to a person |
Most accounting tools let you configure reminders like these. Xero and QuickBooks Online have built-in reminder schedules; tools like Chaser add more control, such as different sequences per customer or escalation to a named person.
Writing reminders that get paid
- Keep it short and specific: invoice number, amount, due date, pay link
- Assume good faith in early reminders (“in case this slipped through”)
- Make it easy to reply with a question
- Send from a real address that someone reads
- Avoid threatening language in automated emails; save firm steps for a human
Step 5: Keep humans in the loop
Automation handles routine reminders. People handle:
- Disputes about the work or the amount
- Customers with cash flow trouble who need a payment plan
- Large or strategic accounts where a phone call is better
- Final steps such as stopping work or using a collection agency
Set a rule that any invoice over a certain amount or past a certain age is flagged to a named person. Exclude specific customers from automated reminders when there is an agreed arrangement.
Step 6: Connect the rest of your workflow
Once invoicing and reminders work, consider:
- Notifications to your team when a large invoice is paid or goes overdue, for example in Slack; see Slack integrations
- CRM updates so account managers see payment status before they call a client, so nobody asks a late payer for more work by mistake
- Pausing services automatically for long-overdue subscriptions, with a warning first
- Monthly reports on days sales outstanding and overdue totals

Step 7: Measure and adjust
Review once a month:
- Average days to payment
- Number of overdue invoices and their value
- Which reminder step most payments follow
- Customers who are regularly late
If most customers pay after the first overdue reminder, try moving the heads-up earlier. If a few customers are always late, talk to them, change terms, or ask for deposits.
Data protection and tone
Reminder emails contain personal and financial information. Send them only to the right contacts, keep customer data in your accounting system rather than in spreadsheets, and check your privacy notice explains how you use contact details for billing. With GDPR coming into force in May 2018, it is a good time to review where invoice data is stored and who can access it.
Tone matters too. Automated does not mean cold. Write reminders as you would speak to a good customer.
FAQ
Will automated reminders annoy customers?
Not if they are polite and accurate. Most customers prefer a reminder to an awkward phone call later.
Can I stop reminders for one customer?
Yes. Most tools let you exclude a contact or a single invoice.
Do I need Zapier for this?
Often not. Built-in reminders in QuickBooks Online, Xero or FreshBooks cover the basics. Zapier helps connect invoices to other tools.
What if a customer pays by bank transfer?
Reconcile bank feeds promptly so paid invoices are marked as paid and reminders stop.
Get paid without chasing
Automated invoicing and payment reminders turn an uncomfortable chore into a routine background process. Put invoices in one system, add a payment link, set a polite reminder sequence and keep a person for the tricky cases.
