The Payment Follow-Up Sequence
Day 1 past due: Friendly reminder
Email + SMS: "Hi [name], just checking in — invoice #[X] for $[amount] was due yesterday. Please let me know if you have questions or if payment is on its way." Short. Warm. No drama yet.
Day 7 past due: Direct follow-up
Phone call first. Then email. "I haven't heard back regarding invoice #[X]. This is now 7 days past due. Please confirm payment date or contact me to discuss." Start documenting in writing.
Day 14 past due: Formal notice
Email with read receipt: "This is a formal notice that invoice #[X] is now 14 days past due. Payment is required within 7 days to avoid additional fees and potential legal action." Now you're building a paper trail.
Day 21+ past due: Escalate
Options: collections agency (takes 25–40% but zero effort), demand letter from an attorney ($200–$500, very effective), or small claims court (under $10,000 in California, no attorney required).
What you want to say: "Pay me or I'll sue you."
What works better: A consistent, documented follow-up sequence that makes non-payment more painful than payment.
The truth: Most non-payment isn't malicious. It's disorganization. The sequence above gets 80% of late invoices paid before day 21.
California Small Claims Court (Under $10,000)
California small claims court is designed for exactly this situation. Filing fee: $30–$75. No attorney required. Most San Diego cases are heard within 70 days. Win rate for businesses with proper documentation: very high. If you have a signed contract, invoices, and documented follow-up attempts, you will almost certainly win.
Preventing Late Invoices
- Get 25–50% deposit upfront before any work starts
- Send invoices same-day as work completion (not end of month)
- Offer ACH/bank transfer (no processing fees, money clears in 1-2 days)
- Include late fees in your contract (1.5%/month is standard and legal in California)
- Use invoicing software with automatic reminders (QuickBooks, FreshBooks, HoneyBook)
Frequently Asked Questions
- How long should I wait before following up on an unpaid invoice?
Follow up the day after the due date. Not a week later. Prompt follow-up signals that you track your invoices and take payment seriously, which sets the tone for resolution. - Can I charge late fees on invoices in California?
Yes — if your contract or invoice terms specify it. 1.5% per month (18% annually) is standard and enforceable. You cannot charge late fees retroactively if they weren't in your original agreement. - How do I take a client to small claims court in San Diego?
File at San Diego Superior Court Small Claims Division. Fee is $30–$75. Bring your signed contract, invoices, and all written communication. Cases are typically heard within 70 days. You don't need an attorney. - Should I use a collections agency for unpaid invoices?
For invoices over $1,000 where you've exhausted follow-up: yes, if you prefer zero effort over maximum recovery. Collections agencies take 25–40%. A demand letter from an attorney ($200–$500) often works better and costs less. - What documentation do I need to collect an unpaid invoice?
Signed contract or proposal, original invoice, proof of delivery/completion of work, and all written communication (emails, texts) about the invoice. This paper trail wins small claims cases.
