How to Get Unpaid Invoices Paid Without Chasing Everyone at Once

It's the last week of the month. Sales look fine, yet there isn't enough in the bank to cover the supplier run. You know some of the gap is sitting in unpaid invoices. You just couldn't say how much, who owes it, or how long it has been out.

Late payment is rarely one big problem. It's usually a dozen small balances that nobody is watching. This guide shows how to see them clearly, chase them in the right order and stop new ones from building up.

Why unpaid invoices stay unpaid

Most overdue balances aren't disputes. They slip for duller reasons:

• Nobody has one list. The figures live across an invoice folder, the till and someone's memory.

• Chasing happens when you remember. The loudest customer gets the call, not the largest debt.

• The customer's records don't match yours. A part payment or a credit note went unrecorded, so the first reply to your reminder is an argument about the amount.

Each step below deals with one of these.

Step 1: Make it easy to pay from day one

The cheapest chase is the one you never have to make. When you send an invoice from Winstia by email or WhatsApp, the message includes a link to view it online. If you've connected a payment gateway, that page also has a Pay online button. If you haven't, it still shows the invoice and your contact details.

Make sure every invoice has a clear due date, too. Everything that follows is measured from it.

Step 2: Read your ageing report every week

Open AR Ageing. It lists every customer who owes you money, largest balance first, split into five columns: Current, 1–30, 31–60, 61–90 and 90+ days overdue. Unpaid invoices are included, and so are credit sales made at the till.

The cards at the top give you four figures: Total Receivable, Current, Overdue and Critical, which is anything 60 or more days past due.

Critical is the number to watch from week to week, because the older a debt gets, the harder it is to collect. You can also export the report as a CSV.

Step 3: Chase in order, with a rhythm

Use the report to decide who to contact and how:

• Current: nothing yet. Leave them alone.

• 1–30 days: a friendly nudge. Often it's simply been forgotten.

• 31–60 days: a direct message with the statement attached, asking for a payment date.

• 61–90 days: a phone call. Agree a date, and part payment if that's what it takes.

• 90+ days: the owner's decision. Pause further credit, agree a plan, or accept the loss.

Within each band, start with the biggest balance. Twenty minutes on the top five names usually does more than an hour working down the alphabet.

Step 4: Send a statement, not an argument

Before you chase, open the customer's ledger. It shows the opening balance, invoices, payments and credit notes in date order with a running balance, plus that customer's own ageing.

From there, you can download the statement as a PDF, export it as a CSV or email it straight to the customer. A statement answers "which invoice?" and "didn't we already pay that?" before they're asked, and it moves the conversation from whether they owe you to when they'll pay.

Step 5: Record what comes in, including part payments

When money arrives, use Record Payment on the invoice and enter the amount, method and date. The invoice shows what's still owed, and a part payment leaves it marked Partial, so the balance on your next statement is right.

If customers pay by bank transfer, you can do this from Bank Reconciliation instead. Import your statement and Winstia suggests which open invoice each deposit belongs to. Accepting a suggestion records the payment and posts it to your books.

Step 6: Stop the next one before it starts

Once a customer has shown a pattern, set a credit limit on their record. When a new invoice would take them over it, Winstia refuses it and tells you why. At the till, a sale on account gets the same check while the register is online.

When a debt really is gone

Some debts won't come back, and leaving them open makes your receivables look healthier than they are. Mark the invoice as Bad Debt and the write-off is posted to your books and shown on the customer's statement. If they pay later after all, the statement shows a recovery. It's worth asking your accountant first, and they can review it through the free accountant portal.

A rhythm that fits in your week

• Weekly (15 minutes): read the ageing report and chase the top five.

• Monthly: email statements to everyone with an overdue balance, and review credit limits.

• Quarterly: look at anything at 90+ days and decide what to do with it.

Getting paid on time is the difference between profit on paper and money in the bank. It only takes a list, a rhythm and a statement both sides can trust.

Winstia keeps your invoices, till sales, payments and double-entry books in one system, so your ageing report and your statements work from the same numbers. Explore the features or book a demo.
