How do I keep track of unpaid customer invoices?
The accounts receivable aging report is your main tracking tool. In QuickBooks or any accounting software, this report lists every unpaid invoice and sorts them by how long they’ve been outstanding. You can see at a glance who owes you money and whether that money is getting harder to collect.
The standard aging buckets are current, 1-30 days past due, 31-60 days, 61-90 days, and over 90 days. Current invoices aren’t late yet. Anything past 30 days needs attention. Past 60 days is a problem. Past 90 days means you’re probably not getting paid without serious effort. The buckets help you prioritize. You don’t chase everything at once. You focus on the aging invoices that are sliding toward uncollectable.
Pull this report weekly. Once a week, review who has fallen into older buckets since last time. This takes five minutes if you stay on top of it. Skip it for a month and you’re surprised by $4,000 sitting in the 90+ column that you forgot about.
Build a follow-up routine based on aging. Send a friendly reminder at 7 days past due. Something simple works: “Just a reminder that invoice #123 is due. Let me know if you have questions.” At 30 days, be more direct: “This invoice is now 30 days past due. Please remit payment by [date].” At 60 days, pick up the phone. At 90 days, decide whether to pursue collections or write it off.
Preventing late payments is easier than chasing them. Invoice immediately after completing work while the value is fresh in your client’s mind. Put payment terms on every invoice and state them clearly during onboarding. Offer online payment options because checks in the mail take longer and give customers an excuse.
If tracking and follow-up take more time than you have, consider outsourcing your invoicing to someone who can handle payment tracking consistently. A dedicated AR process means invoices go out promptly, aging reports get reviewed, and follow-ups happen on schedule.
The businesses that struggle with cash flow often aren’t doing bad work. They’re just not watching what’s owed to them. Good small business bookkeeping on Long Island includes keeping AR current so you’re not funding your clients’ operations with unpaid invoices.

More Questions
Should I pay my cleaners as employees or 1099 contractors?
Classification depends on how the work relationship actually functions, not your preference. Recurring, scheduled cleaners who use your supplies and follow your direction are usually employees under IRS and New York rules. Misclassifying them as contractors can lead to back taxes, penalties, and audits.
Read answerHow do I handle client reimbursements and pass-through expenses in my books?
Record pass-through expenses separately from your operating costs and track reimbursements as offsets rather than income. This keeps your actual revenue and margins accurate instead of inflated by money that just passes through your hands.
Read answerHow far back can a bookkeeper go to clean up my books?
A bookkeeper can go back as far as records exist. Most catch-up projects focus on the last three to six years to cover IRS audit periods and unfiled returns. The main constraint is whether bank statements and other documentation are available to support the reconstruction.
