Accounts receivable for small business: get paid faster

Accounts receivable for small business owners is simple to define and hard to manage: it is the money customers owe you for work you have already done. Every day an invoice sits unpaid, you are lending the customer your cash for free, while your own rent, payroll and suppliers still have to be paid on time. A profitable business can still run short of cash if collections slip, which is why the cash flow statement and the profit figure often tell different stories.

The good news is that getting paid faster is mostly a matter of system, not confrontation. This guide covers clear terms, prompt and correct invoices, the aging report, a follow-up schedule, statements, credit limits, deposits, early-payment discounts, bad debt, and the one metric worth tracking, days sales outstanding.

Set clear payment terms before the work starts

Most late payments start with vague terms. Agree them in writing, in the quote or contract, before you deliver anything:

When payment is due. "Net 30" means the full amount is due 30 days after the invoice date. Shorter terms such as net 15, or due on receipt, are common for small jobs.
How to pay. The payment methods you accept and the details the customer needs, such as your bank details for transfers.
What happens if it is late. Any late fee or interest you intend to charge. States limit these, so check the rules before you set a rate.
Deposits and milestones for larger jobs (covered below).

Repeat the terms on every invoice. A customer's accounts payable clerk may never see your contract, only the invoice.

Invoice promptly and get it right the first time

The payment clock starts when the customer receives a correct invoice, so send it the day the work is delivered, not at the end of the month. A complete invoice includes:

Your business name and contact details, and the customer's legal name and billing address.
A unique, sequential invoice number and the invoice date.
The customer's purchase order number, if they use one. Many businesses will not pay an invoice without it.
A clear description of what was delivered, with quantities, rates and totals.
Any sales tax shown separately, where it applies.
The due date written as a date, not only as "net 30".

Every error, such as a wrong address, a missing PO number or a price that does not match the quote, gives the customer a reason to put the invoice aside. Record each payment against the invoice it pays, so your receivables list stays accurate. Our small business bookkeeping guide explains how invoices and payments fit into the rest of your books.

Read the accounts receivable aging report

The aging report is the most useful accounts receivable tool a small business has. It groups each customer's unpaid invoices by how far past the due date they are. Here is an example for a business with four customers owing a total of $23,000:

Customer	Current	1–30 days	31–60 days	61–90 days	Over 90 days	Total
Harbor Cafe	$4,200	$1,800	$0	$0	$0	$6,000
Ridge Builders	$6,500	$0	$3,000	$0	$0	$9,500
Oak Street Dental	$2,000	$1,500	$0	$1,200	$0	$4,700
Pine Supply	$0	$0	$0	$0	$2,800	$2,800
Total	$12,700	$3,300	$3,000	$1,200	$2,800	$23,000

The names are made up for the example. Reading it: $12,700 (about 55%) is not yet due, and $10,300 (about 45%) is overdue. Of that, $4,000, the $1,200 from Oak Street Dental plus the $2,800 from Pine Supply, is more than 60 days late, about 17% of the total. Those two balances get a phone call this week. Ridge Builders' $3,000 needs a firm reminder, and the small 1–30 day amounts need a polite nudge. The older a receivable gets, the harder it usually is to collect, so work the report from right to left.

A follow-up cadence that gets invoices paid

Decide your follow-up steps once and apply them to every customer, so chasing money stops being personal. A simple schedule for net 30 terms:

Invoice day: send the invoice and confirm the right person received it.
A week before the due date: a short, friendly note that the invoice is coming due.
Due date: a reminder that payment is due today, with the invoice attached again.
7 days late: a phone call. Ask whether there is a problem with the invoice and when payment will be made, and write down the answer.
30 days late: a formal written reminder, and pause new work on credit until the account is current.
60 days late: escalate to the owner on their side, agree a payment plan in writing, or decide whether to use a collection agency or attorney.

Keep notes of every contact in one place, so whoever picks up the account knows what was promised.

Send customer statements every month

A statement lists every invoice, payment and credit on the customer's account and the balance due. Sending one to each customer with an open balance after month end catches invoices they never received, payments applied to the wrong account and disputes you did not know about. It also fits naturally into your month-end close, when you review receivables anyway.

Credit limits, deposits and early-payment terms

Set credit limits

Before you extend credit, decide how much each customer may owe at once. Start new customers low and raise the limit as they pay on time. Ask for trade references or check a business credit report for larger accounts. When a customer reaches their limit, new orders wait until older invoices are paid.

Take deposits on larger jobs

A deposit reduces your risk and covers materials up front. For example, a 30% deposit on an $8,000 project is $2,400 paid before work starts, leaving $5,600 due on completion. On long projects, bill by milestone instead of waiting until the end.

Consider early-payment discounts carefully

Terms written as "2/10, net 30" offer a 2% discount if the customer pays within 10 days, with the full amount due in 30. On a $5,000 invoice the customer would pay $4,900 by day 10, so the discount costs you $100. That is an expensive way to borrow: giving up 2% to be paid 20 days sooner works out to roughly 37% a year (2 ÷ 98 × 365 ÷ 20). It can still make sense when cash is tight, but compare it with your other options first.

Bad debt, in brief

Some invoices will never be paid. When you have made real collection efforts and there is no reasonable prospect of payment, write the balance off as a bad debt expense, so your receivables and your profit reflect reality. For tax, the IRS explains in Topic 453, Bad debt deduction that you generally can deduct a business bad debt only if the amount was already included in your income, which usually rules it out for cash-basis businesses, and only in the year it becomes worthless. Your CPA can confirm the treatment. If a written-off customer later pays, record the recovery.

Track days sales outstanding (DSO)

Days sales outstanding tells you, on average, how many days it takes to collect after a sale on credit. The formula is:

DSO = accounts receivable ÷ credit sales for the period × days in the period

Example: a business made $135,000 of credit sales in a 90-day quarter and had $45,000 of receivables at the end of it. DSO = $45,000 ÷ $135,000 × 90 = 0.3333 × 90 = 30 days. On net 30 terms, customers are paying about on time.

Now suppose tighter follow-up cuts ending receivables to $36,000 on the same sales. DSO = $36,000 ÷ $135,000 × 90 = 24 days, and $9,000 has moved from customers' hands into your bank account. Calculate DSO the same way every month or quarter and watch the trend; a rising number is an early warning, long before the bank balance shows it. The cash flow statement shows the same effect: a fall in receivables adds to operating cash flow.

Managing accounts receivable for a small business in one system

Spreadsheets can track a handful of invoices, but they do not tie invoices to payments or age balances automatically. BMS Prime records invoices and customer payments on a double-entry ledger in US dollars, keeps the receivables aging up to date, can create repeating invoices on their dates, and puts your logo on invoices and statements. It does not connect to bank feeds, so you record payments as they arrive. See what is included on our HR and accounting software for US small businesses page; accounting is included from the Growth plan (6 to 20 employees) upward, and you can compare plans by team size.

Whatever tool you use, accounts receivable for a small business comes down to habits: clear terms, same-day invoices, a weekly look at the aging report and a follow-up schedule you actually keep.

Frequently asked questions

What is accounts receivable in simple terms?

Accounts receivable is the money customers owe you for goods or services you have already delivered on credit. Each unpaid invoice is a receivable. It appears on your balance sheet as an asset, because you expect to collect it, usually within weeks. When the customer pays, the receivable goes down and your bank balance goes up by the same amount.

What is a good DSO for a small business?

There is no single good number, because it depends on your industry and your terms. A useful test is to compare days sales outstanding with your own payment terms. If you offer net 30 and your DSO is close to 30, customers are paying roughly on time. If it is well above your terms, look at the aging report to find which customers are slowing you down.

How often should I send customer statements?

Most businesses send statements once a month, shortly after month end, to every customer with an open balance. A statement lists the invoices, payments and credits on the account and the balance due, often with aging. It catches missed invoices, payments applied to the wrong account and disputes before they grow.

When should I write off a bad debt?

Write off a receivable when you have made real collection efforts and there is no reasonable prospect of being paid. Record it as a bad debt expense so your receivables reflect what you can actually collect. For tax, the IRS generally allows a business bad debt deduction only if the amount was already included in income, so cash-basis businesses usually cannot deduct it. Ask your CPA.

Should I charge late fees on overdue invoices?

You can, if the fee is stated in your terms before the work starts and the customer has agreed to them. State laws limit how much interest or late charges you can apply, so check your state's rules or ask an attorney before setting a rate. Many small businesses find that a clear due date and a prompt reminder work better than fees.
