Learning how to manage accounts receivable means treating it as a cycle: a credit decision before the sale, an accurate invoice after it, steady follow-up, and measurement at the end. By the end of this guide you will have a working process that covers credit terms, invoicing, recording, reminders, dispute handling, escalation, and reporting. Before you start, gather a list of your current customers, their open invoices, and access to your accounting software or a spreadsheet where you track what customers owe.
Step 1: Set Clear Credit Policies and Payment Terms
Accounts receivable is money customers owe you for goods or services already delivered. Every dollar of it is an unsecured loan, so decide deliberately who gets one. Extending terms to everyone by default is how a business ends up financing customers it knows nothing about.
Start with a short credit application for new customers on terms. Ask for:
- The customer's legal name and business address
- A billing contact, plus the accounts payable contact if different
- Two or three trade references you can actually call
Then set a credit limit for each customer, the maximum unpaid balance you will carry. A new customer might start low and rise after a few on-time payments. Customers who decline to complete the application can be offered payment upfront or a deposit.
Next, choose standard payment terms. Net 30 means the full amount is due 30 days after the invoice date; Net 15 shortens that, and due on receipt asks for payment immediately. Shorter terms bring cash in sooner, but they need to be realistic for your industry and customers.
You may also offer an early-payment discount, such as 2/10 net 30: a 2% discount if paid within 10 days, otherwise the full amount in 30. Check the math first. A 2% discount on every invoice is a real cost to your margin, and customers who would have paid on time anyway will simply take it.
Finally, write it all down. Late fees, interest charges, and your collections process should appear on quotes, contracts, and invoices, so nobody can claim surprise later. Have an attorney confirm that your late-fee amounts are permitted in your state, since rules on fees and interest vary and can differ for consumers versus businesses.
Step 2: Invoice Accurately and Immediately
The payment clock usually starts on the invoice date, so a delay in sending the invoice is a delay in getting paid. Send the invoice when the work is delivered or the goods ship, not at the end of the week or month when you get around to billing.
Every invoice should carry these details:
- A unique invoice number
- The customer's purchase order (PO) number, if they use one
- An itemized description of what was delivered, with quantities and prices
- A due date written as a calendar date, such as October 30, rather than only "Net 30"
- Payment instructions, including who to pay and how
Late payment is often blamed on customers when the real cause is on your side: a missing PO number, a vague description, or a total that does not match the quote. Those errors get an invoice kicked back or parked in a queue, and nobody tells you.
Send it to the person who approves payment
Your day-to-day contact is often not the person who releases payment. Many companies route invoices through an accounts payable department or a dedicated inbox. Ask at the start of the relationship who should receive invoices, and get that address in writing. An invoice sent to a project manager who forwards it a week later has already lost a week.
Make paying easy
Offer at least one electronic option, such as ACH bank transfer, card payment, or an online payment link on the invoice. The fewer steps between reading the invoice and paying it, the faster it happens. If you pass card processing fees to the customer, say so on the invoice and confirm that surcharging is allowed where you operate, since card network and state rules on this can change.
Step 3: Record Receivables and Set Up an Aging Report
Every invoice needs to live in one system, whether that is accounting software or a well-kept spreadsheet. For each one, record the customer, amount, invoice date, and due date. Revenue recorded is not cash in hand, and this record is what tells you the difference.
The core tool is the A/R aging report, which lists unpaid balances by customer and groups them by how overdue they are. The standard buckets are:
- Current (not yet due)
- 1 to 30 days past due
- 31 to 60 days past due
- 61 to 90 days past due
- Over 90 days past due
Most accounting packages generate this report in a couple of clicks. In a spreadsheet, add a column that subtracts the due date from today's date and sort or filter by the result.
The report matters because it tells you where to act. Suppose one customer has $4,000 sitting in the 61 to 90 bucket, and another has $400 in the 1 to 30 bucket. The first needs a phone call this week, a review of whether they are still within their credit limit, and possibly a pause on new orders. The second probably needs a reminder email and nothing more. Without the aging view, both look like "overdue."
Once a month, reconcile the A/R subledger (the detail of who owes what) to the accounts receivable balance in your general ledger. The two totals should match. When they do not, the usual culprits are payments received but never applied to an invoice, credits entered without being linked to a customer, and duplicate entries. Left alone, these distort your aging report and lead you to chase customers who have already paid.
Step 4: Build a Reminder and Follow-Up Schedule
A written schedule removes the guesswork and the awkwardness. Decide the timing once, then follow it for every customer. A workable cadence looks like this:
- A friendly reminder a few days before the due date, with the invoice attached
- A short note on the due date itself
- A follow-up 3 days after the due date
- A firmer follow-up at 10 days late, ideally by phone
- A written notice at 30 days late that references your late-fee terms
Adjust the intervals to your terms and industry, but keep them fixed. A reminder is not an accusation. Most customers treat a polite prompt as routine, and many are grateful because invoices genuinely get buried. The idea that reminders damage relationships is mostly a misconception; vague, late, or inconsistent contact does more harm.
Escalate the channel as the balance ages. Automated email is fine for the first touches. When a balance is 10 or more days late, call and speak to a real person, ideally the one who processes payments. If that fails, send a formal letter that states the amount, the invoice numbers, the original terms, and a date by which you expect payment.
Keep a record of every contact in the customer's file: the date, who you spoke with, what was said, and any promise to pay. If a customer says the check goes out Friday, note it, and check on Monday. This log also protects you if the account later goes to a collection agency or attorney.
The most common mistake is silence. Waiting until an invoice is 60 days late before the first contact hands the customer two months of free financing and makes the conversation harder for everyone.
Step 5: Apply Payments and Resolve Disputes Quickly
Apply each payment to the correct invoice the day it arrives. Use the remittance details, the check stub or ACH note, to see exactly which invoices the customer meant to pay. If a payment sits unapplied, your system will keep showing the invoice as open, and your reminder schedule may send a dunning notice to a customer who paid on time. That is a fast way to irritate a good customer.
When a customer does not pay because they disagree with the invoice, treat it as a dispute, not a collections problem. Work through it in this order:
- Find the cause. Typical reasons are a price that differs from the quote, a quantity or delivery discrepancy, a quality complaint, or a missing PO number.
- Assign one owner on your side, so the customer is not passed between people.
- Set a resolution date and put it in writing.
If the correction is agreed, issue a credit memo, a document that reduces what the customer owes and references the original invoice. Do not edit or delete the original. Leaving it intact and adding a credit memo keeps the audit trail clear, which matters for your accountant and for any later review.
Disputes rarely cover the whole invoice. Where part of the amount is not in question, ask for it now. Something like "we will resolve the $600 freight question separately, but the remaining $3,400 is undisputed and due on the 30th" keeps cash moving and stops one issue from freezing the entire balance.
Step 6: Escalate Overdue Accounts and Decide on Write-Offs
Some accounts will not respond to reminders. For those, move up a defined ladder instead of improvising:
- Pause new orders or credit until the past-due balance is addressed.
- Send a formal demand letter with the balance, the deadline, and the consequences.
- Offer a written payment plan with specific dates and amounts, signed by the customer.
- Consider referring the account to a collection agency or an attorney.
Before you refer anything, weigh cost against balance. Collection agencies typically keep a percentage of what they recover, and attorneys may charge hourly or contingent fees. Confirm the fee structure in writing. On a small balance, a firm demand letter and a payment plan may net more than a referral.
Time also matters. Every state sets a statute of limitations on how long you have to sue to collect a debt, and it varies by state and by type of contract. Do not let an old balance drift past that window. Ask your attorney what applies to you.
Estimating versus writing off bad debt
When an account is truly uncollectible, you have two accounting approaches. The allowance method estimates future bad debt ahead of time, recording an allowance for doubtful accounts that reduces your receivables and expenses the estimate as you go. The direct write-off method waits until a specific invoice is deemed uncollectible and then removes it. Which one applies to your business, and how bad debt is treated for tax purposes, depends on your accounting method and circumstances. Have your CPA advise you before you write anything off.
Step 7: Track Key Metrics and Review the Process Monthly
A process you never measure will drift. Three numbers cover most of what a small business needs.
Days sales outstanding (DSO) is the average number of days it takes to collect payment after a credit sale. The formula is accounts receivable divided by credit sales, multiplied by the number of days in the period. For example, imagine $60,000 in receivables at month-end, $90,000 in credit sales for the 30-day month: 60,000 / 90,000 x 30 = 20 days. Compare the result to your stated terms. A DSO well above your terms means customers are paying late on average. Benchmarks differ widely by industry, so compare yourself to your own history first, and check industry sources before using an outside figure.
Percentage of receivables past due is your past-due balance divided by total receivables. Collection effectiveness looks at how much of what was collectible during the period you actually collected. Set a target for each and compare month to month; the trend tells you more than any single reading.
The monthly review
Set aside an hour each month to:
- Read the full aging report, not just the total
- List the top five overdue balances and assign a next action and date to each
- Flag customers who repeatedly pay late, and revisit their terms or credit limits
- Check whether late payments trace back to your own invoice errors or unclear terms
As volume grows, consider automating invoicing, reminders, and payment links. Many accounting platforms include these features, but what is included and what it costs changes often, so confirm current features and pricing as of today before buying, and check that the tool works with your existing accounting software.
Start With an Aging Report This Week
Run an aging report this week. It shows you exactly where your cash is stuck and which of the steps above matters most right now. From there, work through the process in order: tighten your credit terms, fix your invoices, set the reminder schedule, and put the monthly review on your calendar. Once it is running, it takes far less effort than chasing invoices ad hoc.
Before you finalize anything, review the process with your CPA or accountant to confirm it fits your tax and legal situation, especially late fees, write-offs, and collection steps.
