Aging debt: how to build a weekly chase routine that gets invoices paid
In short
An aging debt report groups unpaid invoices into time buckets that show collection risk by age. Pull it every Monday, assign a named owner to each overdue invoice, and work through the bucket-specific chase sequence in this guide to keep cash moving.
- Collection probability on a 90-plus day invoice drops below 73% and falls by roughly one percentage point per additional week - acting in the 31-60 day window is always cheaper.
- Running your aging report every Monday and naming a specific owner for each overdue invoice removes the ambiguity that lets debts age unnoticed.
- Each aging bucket needs a pre-decided action: automated reminders for 1-30 days, phone calls at 31-60, senior escalation at 61-90, and a documented decision at 90-plus.
- Logging every contact attempt creates the evidence you need if a debt goes to a third-party collector or requires a write-off.
- Separating disputed invoices from the standard chase cadence protects customer relationships while keeping the routine running for straightforward late payers.
An aging debt report groups every unpaid invoice into time buckets. This guide walks through reading those buckets on Monday morning, setting trigger-based chase actions for each age band, and escalating before debt becomes uncollectable.
An aging debt report groups every unpaid invoice into time buckets by how long it has been overdue. On Monday morning, those buckets tell you three things at a glance: how much money is at risk, how urgent each account is, and which actions your team needs to take before the week gets away from you. The report is not a scorecard to review and file. It is the starting point for a structured chase sequence that prevents overdue invoices from quietly migrating into the zone where collection becomes expensive or impossible.
What the aging buckets are actually telling you
Standard aging reports divide outstanding invoices into five columns: current (not yet due), 1-30 days past due, 31-60 days past due, 61-90 days past due, and 90 or more days past due. The column totals are the first thing to read on any review session. If more than 20% of your receivables sit beyond 60 days, that is a warning that your collection process has a gap - not just that a few customers are slow (Invoice Butler, 2026).
The economics behind each bucket matter more than most businesses realize. Invoices in the current and 1-30 day columns carry a collection probability above 95% with proactive follow-up. By 31-60 days, that figure drops to the 85-90% range. At 61-90 days, it falls further to 73-80%. Once an invoice passes 90 days, collection probability drops below 73% and falls by roughly one percentage point for every additional week of inaction (Beancount.io, 2026). After six months past due, the odds of recovering the full balance fall below 50%.
These are not abstract statistics. They mean that an invoice sitting in your 90+ column today was worth more to your business three weeks ago, and will be worth measurably less three weeks from now. The value of the weekly routine is that it stops invoices from aging through the buckets unnoticed.
The 90-day collection rate
Debts over 90 days past due average only a 69.6% collection rate, citing data from Quadient. Acting in the 31-60 day window, when the rate is still 85-90%, is materially cheaper than trying to recover the same invoice three months later.
The weekly chase sequence, step by step
Pull your aging report first thing on Monday morning
Run your aged receivables report before anything else fills the day. Xero labels this Aged Receivables, QuickBooks calls it A/R Ageing, and most accounting platforms generate it automatically. If your invoicing and job management live in separate systems, make sure both are reconciled before you read the figures. An invoice recorded in your job management system but not yet pushed through to your accounting software will not appear on the report, and a genuine overdue balance will look invisible until it is already old.
Read bucket totals before individual rows
Look at the column totals first. The pattern across buckets tells you the health of your receivables at a business level before you get into individual accounts. A growing 31-60 day column month over month signals that your 1-30 day chase is not landing. A growing 90+ column signals an escalation failure from six to twelve weeks earlier. Catching the pattern early gives you time to fix the process, not just chase the symptom.
Assign a named owner to every overdue invoice
Every invoice in the 1-30 day and older buckets needs a specific person responsible for the next action - not "accounts" as a team, but a named individual. In a small business this might always be the same person, but naming them on the chase board creates accountability and ensures nothing gets lost between handovers. If your reporting tool allows it, add an owner column. If it does not, export to a simple spreadsheet and add one manually before the week begins.
Automate the 1-30 day bucket so your team can focus elsewhere
Invoices in the current-to-30-day window should be handled by an automated reminder sequence, not by manual email. The action needed here is light: a prompt that the invoice is due or recently overdue, sent with a payment link. Setting this up through your invoicing platform's automations means your team's attention can focus on the 31-60 day and older buckets where a human conversation is what actually moves the debt. A light-touch sequence at day 1, day 7, and day 14 past due captures the straightforward late payers without any manual intervention.
Work the 31-60 day bucket by phone
At 31-60 days, email reminders alone are not working. Pick up the phone. A direct conversation surfaces the real reason for non-payment faster than another written reminder. Ask clearly: "Invoice [number] is now [X] days overdue - is there anything we need to resolve on our end?" The answer will tell you whether this is a process problem on the customer's side (invoice lost or waiting on approval), a dispute, a cash flow issue, or a customer who is not prioritizing payment. Each answer requires a different response, and you cannot determine which one applies without speaking to someone. Also copy in the account manager on any follow-up email - the customer relationship can accelerate resolution.
Escalate the 61-90 day bucket to decision-makers
When an invoice reaches 61-90 days, continuing to chase the same contact who has already ignored two reminders and a phone call is unlikely to help. Have a senior person from your business contact a senior counterpart at the customer's business. Put a hold on any additional work or shipments to that customer while the debt remains unresolved. Send a formal written notice with a specific deadline for response. Document every contact attempt, because you may need that paper trail if the debt eventually goes to a third-party collector or requires legal action.
Make a decision on every 90-plus day invoice before the session ends
Every invoice in the 90+ bucket needs a decision this week - not next week, and not "ongoing chase." The three practical options are: send a final demand letter with a deadline and stated consequences; refer the debt to a third-party collections agency (which typically takes 25-50% of any recovered amount); or write the balance off as bad debt and take the appropriate tax treatment. Leaving the 90+ bucket on the report without a decision is not neutral. It wastes chase time every Monday and distorts your view of the cash that is actually collectable.
Log every contact attempt before you close the session
Before Monday's session ends, update your record for every invoice you chased. Note the date, the method (call, email, written notice), who you spoke to, and what they said or agreed to. This log is not administrative overhead. It is the evidence that you pursued the debt in good faith, which matters for bad debt write-off treatment and for any escalation to a collector or solicitor. A log with no entries makes the debt harder to justify writing off and the recovery harder to argue.
Setting chase triggers so the routine runs without you
A chase routine breaks down when it depends on someone remembering to apply judgment each week. The fix is to define your triggers before the week starts - fixed rules that tell your team what action is required at each bucket threshold - and record them somewhere permanent.
A workable trigger set: invoices moving into the 1-30 day bucket trigger an automated reminder within 24 hours of the due date; any invoice crossing 31 days triggers a phone call within two working days; any invoice crossing 61 days triggers a senior escalation email that same week; any invoice crossing 90 days triggers a formal written notice and a documented decision within five working days. These rules remove the judgment call from the process. Your team does not need to decide whether an invoice is serious enough to escalate - the number of days past due decides for them.
Checking the week's bucket movements through your reporting tools gives you the visibility to spot a growing 31-60 day column before it feeds the 90+ bucket six weeks later. That early view is worth more than any amount of intensive chasing once the debt is already old.
64% of small businesses carry invoices on their books that are 90 days or more past due (Beancount.io, 2026). The week-by-week routine exists precisely to stop your business becoming part of that figure.
Handling disputed invoices without breaking the chase cadence
Not every overdue invoice is a collection problem. Some sit in the overdue columns because the customer is disputing the amount, the scope of work, or the payment terms. Chasing a genuinely disputed invoice the same way you chase a straightforward late payer damages the relationship without resolving the underlying issue.
When you identify a dispute during Monday's review, pull it out of the standard chase sequence and handle it on its own track. Assign it to whoever owns that customer relationship, not the credit control process. Resolve the commercial issue first - issue a corrected invoice or credit note as required - and restart the payment clock from that date. A dispute resolved in week one costs far less than a debt that sits in the 90+ bucket because nobody wanted to have the difficult conversation.
Clear invoices help here. Your invoices should carry a job reference, a description of the work covered, and the agreed payment terms. If a dispute keeps returning to the same ambiguity on every job for the same customer, that is a signal to improve your invoicing template or tighten your terms on new orders with that account.
Keeping the routine tight also means separating the repeatable from the exceptional. Automating the reminder cadence for undisputed invoices through your platform's automations frees Monday's session to focus on accounts that need a judgment call - the disputes, the escalations, and the 90+ decisions that no automated sequence can substitute for.
