Accounts receivable management for small businesses
Most small businesses are profitable on paper and short of cash in the bank, because the money sits with customers who have not paid yet.

In short
Accounts receivable management means knowing who owes you what, since when, and acting on it every week. Set terms on every invoice, review the ageing report, send statements and follow up by bucket. SimpleERP keeps every invoice balance and ageing bucket current.
What is accounts receivable management?
Accounts receivable management is the routine of giving credit on purpose, tracking every unpaid invoice against its due date and collecting before the money goes stale. Older books call it the debtors list.
A sale on credit is an interest-free loan to your customer. Managing it has six parts:
- Terms: credit days and a due date on every invoice.
- Credit control: a credit limit per customer, checked before you sell.
- Recording: every payment matched to the invoices it pays.
- Visibility: an ageing report and a statement of account per customer.
- Follow-up: reminders, calls and, at the end, stopping supply.
- Clean-up: credit notes, settlement discounts and bad debt write-offs.
Why does every invoice need terms and a due date?
An invoice without a due date is never overdue, so nobody chases it. The due date is the invoice date plus the customer's credit days, and it should be printed on the invoice where the customer's accounts team will see it.
Agree the credit days when you open the account, write them down, and keep them the same on every document. If a customer gets 30 days, an invoice dated 3 October 2026 is due on 2 November 2026.
How many days and how much credit to give each customer is a decision of its own. The guide on credit limits and credit days for customers works through five customers with the reasoning for each limit.
How do you read an accounts receivable ageing report?
An ageing report splits what each customer owes into buckets by how far past the due date it is: not yet due, 1–30 days, 31–60 days, 61–90 days and over 90 days. The older the bucket, the lower the chance of collecting it in full.
Here is Harbour Steel Furniture, the fictional maker of steel racks and office furniture used across this site, on 1 July 2026, with amounts in US dollars. It is owed $84,000 by six customers.
| Customer | Not due | 1–30 | 31–60 | 61–90 | Over 90 | Total |
|---|---|---|---|---|---|---|
| Oakfield Traders | $18,000 | $6,000 | $24,000 | |||
| Anchor Enterprises | $9,000 | $4,000 | $3,000 | $16,000 | ||
| Northline Office Interiors | $6,000 | $4,000 | $5,000 | $15,000 | ||
| Green Valley School | $10,000 | $4,000 | $14,000 | |||
| Riverside Stores | $5,000 | $3,000 | $8,000 | |||
| Summit Hostel Supplies | $3,000 | $4,000 | $7,000 | |||
| Total | $48,000 | $17,000 | $7,000 | $8,000 | $4,000 | $84,000 |
Illustration of receivables ageing: 2,441 to collect across 5 buckets, with customer totals.
The number to watch is the share over 60 days. At Harbour Steel it is $12,000 of $84,000, about 14%, and two customers account for all of it. The debtors ageing report guide covers ageing by invoice date versus due date and how partial payments sit in a bucket.
What should you do with each row of the ageing report?
Each row needs one action this week, chosen by its oldest bucket, not by its total. A large balance that is not yet due needs less attention than a small one that is 90 days late.
| Customer | Oldest bucket | Action this week |
|---|---|---|
| Oakfield Traders | 1–30 | Send the statement; $6,000 is just past due on a reliable account |
| Anchor Enterprises | 31–60 | Call the accounts person about the $3,000 invoice and agree a date |
| Northline Office Interiors | 61–90 | Call the owner; hold new orders until the $5,000 is paid |
| Green Valley School | 1–30 | Send the statement; schools often pay in batches, so ask for the next one |
| Riverside Stores | 1–30 | Copy the reminder text and send it from your phone |
| Summit Hostel Supplies | Over 90 | Stop supply, send a final statement, and decide on a write-off |
How do credit limits stop the problem before it starts?
A credit limit caps how much one customer can owe you at any time, so a slow payer cannot grow into a large loss. The time to apply it is when the next invoice is raised, not when the ageing report turns red.
Summit Hostel Supplies reached $7,000 because each new order looked small on its own. A limit of $5,000 would have flagged the invoice that took it over, and the conversation about the old balance would have happened 60 days earlier.
How should customer payments be recorded and allocated?
Record every payment against the specific invoices it pays, not just against the customer. If Anchor Enterprises pays $4,000 and you only reduce its total, you lose track of which invoice is still open and the ageing report becomes guesswork.
- One payment can clear several invoices, oldest first unless the customer says otherwise.
- One invoice can take several part payments; it stays partially paid until the balance is zero.
- Money received before an invoice, or without a reference, sits on the customer as an advance and is applied later.
- Withholding tax the customer deducts, where your country has it, is a short payment, not a discount. Many businesses record it as tax withheld receivable; confirm the treatment with your accountant.
The partial payments and allocation guide shows $5,000 received against three invoices, with the balances that result.
Why does a statement of account get you paid faster than a reminder?
A statement of account shows the customer every invoice, payment and credit note in date order with a running balance, so there is nothing to argue about and nothing to look up. A reminder about one invoice invites the reply that it was already paid.
Send a statement to every customer on the first of the month and to overdue customers every week. The statement also surfaces disputes early: a missing credit note or a payment posted to the wrong party shows up as a difference between their ledger and yours. The statement of account guide has wording for routine, overdue and final notices.
What follow-up works at each stage of overdue?
Follow-up should step up on a fixed schedule so that customers learn your pattern and nobody has to decide each time. A schedule many small businesses use:
3 days before the due date
A short, friendly reminder with the invoice number, amount and how to pay.
7 days past due
A phone call to the person who releases payments. Ask for a date, not a promise.
30 days past due
A statement with the overdue rows marked and a second call, this time to the owner.
60 days past due
New orders on hold until the oldest invoice is cleared. Say so in writing.
90 days past due
A final statement and, if needed, a legal notice. Discuss a provision or write-off with your accountant.
Seven practices that shorten the wait, from invoicing the same day to making payment a single step, are in how to collect payments faster from customers.
Can the law help you get paid on time?
Several countries give suppliers a legal right to interest on late business payments, and some cap the payment terms large buyers may impose on small suppliers. The details, rates and who qualifies differ from country to country, so check what applies where you trade.
- Put your payment terms in writing on the quotation, the order and the invoice, so any statutory right has an agreed date to run from.
- Keep the terms you agree within any legal maximum where you trade.
- Mention the right to interest on your statement only after your accountant confirms you have it.
In India, micro and small suppliers registered under Udyam are covered by the MSME 45-day payment rule (India), with interest on late payment and a tax incentive for buyers to pay on time.
How do credit notes and settlement discounts fit in?
A credit note reduces what a customer owes for a reason you agree with: goods returned, a rate error, or a discount for paying early. It should always be a document, never a quiet edit to the invoice or a short payment you ignore.
Suppose Green Valley School offers to clear a $10,000 balance this week if you allow 2%. A credit note for $200 against the invoice settles it cleanly, and the statement shows why the balance is zero. Whether that credit note can also reduce the tax on the original invoice depends on your country's rules and on how and when the discount was agreed, so check with your accountant. The credit note entry in the glossary covers the document itself.
How do you write off a bad debt?
A bad debt is written off with a journal that moves the balance from the customer to an expense account, once you have a reason to believe it will not be paid. The invoice stays in your records; only the receivable is cleared.
Summit Hostel Supplies has closed its business. After a final notice, Harbour Steel decides the $4,000 over 90 days will not be recovered, and keeps chasing the $3,000 that is 61–90 days old. The journal:
| Account | Debit | Credit |
|---|---|---|
| Bad debts (expense) | $4,000 | |
| Summit Hostel Supplies (receivable) | $4,000 | |
| Total | $4,000 | $4,000 |
The tax you paid over on the original sale does not come back simply because the customer did not pay. Many VAT and GST systems offer bad debt relief after a waiting period and on conditions, so ask your accountant whether you can claim it. A bad debt write-off is not a credit note and does not change your sales register. If the money is later recovered, reverse the journal and record the receipt as usual.
What is DSO and how do you calculate it?
Days sales outstanding, or DSO, is the average number of days it takes you to collect a sale. It turns the ageing report into one number you can track month to month.
| Step | Figure |
|---|---|
| Receivables today | $84,000 |
| Credit sales in the last 90 days | $210,000 |
| Average sales per day ($210,000 ÷ 90) | $2,333.30 |
| DSO ($84,000 ÷ $2,333.30) | 36 days |
Compare DSO with your usual credit days. Close to it means collections are on time; well above it means money is stuck. If Harbour Steel brought DSO down to 30 days on the same sales, it would hold about $70,000 in receivables, freeing roughly $14,000 of cash without selling a single extra rack.
What does a weekly collections routine look like?
A weekly routine of under an hour does more for cash than any one-off recovery drive. Pick a fixed morning, Monday works for most, and go through the same list:
- Every invoice from last week is posted, with the customer's credit days and due date
- Every payment received is recorded and allocated to the invoices it pays
- Open the ageing report and sort by the oldest bucket, not by total
- Choose one action per overdue customer and note the promised date
- Send statements to every customer with anything overdue
- Make the calls for anything past 7 days and confirm the dates in writing
- Hold new orders for any customer over the limit or past 60 days
- Note DSO and the share over 60 days, and compare with last week
How does SimpleERP handle accounts receivable?
In SimpleERP, every customer carries payment terms, credit days and a credit limit, and every posted invoice writes the receivable, the sale and the tax in one step. When an invoice takes a customer over the limit, you see a warning before posting; it does not block, and posting needs the approve permission anyway.
- One payment can be allocated to many invoices, and one invoice can take many payments.
- Advances and on-account amounts sit on the customer and can be applied to invoices later.
- Posted, partially paid and paid are set by the database from the allocations, so nobody edits a status.
- Cancelling a payment re-opens the invoices it paid, with the history kept.
- Receivables ageing by party and by due date, with bucket columns and a row that expands to invoices.
- A statement of account per party with opening balance, running balance and an ageing footer, to print, save as PDF or copy as share text.
- Reminder text to copy and send from your own email or phone.
- In India, a UPI QR code can also be printed on the invoice.

FAQ
Questions, answered
What is the difference between accounts receivable and accounts payable?
Accounts receivable is money your customers owe you for sales on credit. Accounts payable is money you owe your suppliers for purchases on credit. Both are managed with an ageing report by due date, but receivables are what you collect and payables are what you pay.
How often should a small business review its receivables?
Weekly. A fixed weekly review of the ageing report, with one action per overdue customer, catches late payers while the amounts are still small. Send statements to all customers monthly and to overdue customers every week.
What is a good DSO for a small business?
A good DSO is close to the credit days you give. If most customers get 30 days and your DSO is 32, collections are healthy. If it is 50, money is stuck with customers. Track the trend month to month rather than chasing a single target.
When should I write off a bad debt?
Write off a debt when you have good reason to believe it will not be paid, for example when the customer has shut down or recovery would cost more than the amount. Decide with your accountant, post a journal to a bad debts expense account, and reverse it if the money is later recovered.
Can I charge interest on late payments from customers?
Often yes, if your terms allow it in writing, and in several countries the law gives suppliers a right to interest on late business payments even without a clause. The rate and the conditions differ by country. Confirm with your accountant before you claim it.
