Accounts receivable software tracks the money your customers owe you, chases the invoices they have not paid, and reports on how much is outstanding and for how long. The category name comes from accounting departments, but the job is the same at any size: know who owes you, follow up without having to remember to, and see the whole picture without rebuilding it by hand every Monday.
Search the term and most of what you find is built for finance teams processing thousands of invoices a month. A freelancer with nine clients does not need cash application or credit risk scoring. The useful question is not which AR platform is best, it is how much of this your invoicing tool already does.
What accounts receivable software actually does
It keeps a live list of who owes you, and for how long
The core artefact is a list of every unpaid invoice sorted by how overdue it is. In accounting software this is the accounts receivable aging report, and it groups invoices into buckets: current, then 1 to 30 days past due, 31 to 60, 61 to 90, and 91 and over. QuickBooks documents both a summary version, totals per customer per bucket, and a detail version listing each transaction. The buckets are conventional rather than legally fixed, and QuickBooks lets you change the interval from 30 days to 15 if your terms are shorter.
It does the chasing on a schedule
Instead of you noticing that an invoice went past due nine days ago, the software emails the client on a schedule you set. The better implementations escalate, so a soft nudge goes out a day after the due date and a firmer one at thirty, and let you switch the sequence off for the one client you would rather call.
It tells you what is coming in
Above the level of any single invoice, it rolls up total outstanding revenue, which customers are habitually slow, and roughly what you can expect to collect in the next few weeks. That last number is the one that decides whether you can take on a contractor next month.
The follow-up should not depend on you remembering
Billbooks sends automatic past-due reminders at intervals you choose, and tells you when a client has opened the invoice. Both are on every paid plan. Free for 30 days, no credit card needed.
Why late payment is a system problem, not bad luck
It is worth being clear about the scale, because the instinct is to treat a late invoice as a one-off. In January 2025 Intuit QuickBooks surveyed 2,487 US small businesses with 0 to 100 employees. Over half, 56 percent, were owed money on unpaid invoices, averaging 17,500 dollars per business. Nearly half, 47 percent, had invoices more than 30 days overdue, and close to one in ten of all their invoices fell into that band.
The same report found that businesses more exposed to late payment were likelier to report cash flow problems, leaned harder on credit cards, and had more difficulty hiring. That is the part worth sitting with. Late payment does not only postpone revenue, it changes how the business has to operate while it waits, and those decisions are hard to reverse once made.
Spreadsheet, invoicing tool, or a dedicated AR platform
What a spreadsheet cannot do
A spreadsheet will hold the list. It will not email anyone, and it is accurate only as far as the last time you updated it, which in practice means it is accurate on the day you build it and drifting every day after. The failure is quiet: nothing tells you the sheet is stale.
What invoicing software already covers
Most invoicing tools already track whether an invoice is paid, unpaid or overdue, and many add automatic reminders on top. For a business sending tens of invoices a month rather than thousands, that is the whole job. Buying a second system to do it again is a common and expensive mistake.
What enterprise AR platforms add, and who needs it
Dedicated AR automation adds cash application, which matches incoming bank payments to the right invoice without anyone keying it in, plus credit risk scoring on customers and consolidated reporting across subsidiaries. Each of those earns its cost at volume. The honest threshold is this: if matching payments to invoices is not yet taking someone hours a week, you are paying to solve a problem you do not have.
What to look for, in the order it matters
Reminders that escalate, and that you can switch off
One generic email at day seven is barely better than nothing. Look for a schedule you control, more than one touchpoint as an invoice ages, and per-invoice control, because there is always a client relationship you want to handle by phone instead.
Visibility of how old the debt is
You want to tell at a glance which invoices are merely late and which are old enough that the conversation has to change. Whether that arrives as formal aging buckets or as an outstanding balance per client matters less than whether you can see it without exporting anything.
Payment collection on the invoice itself
A payment link on the invoice removes the step where the client means to pay and then does not. Every reminder you avoid sending is worth more than a reminder that works.
A report you can hand to an accountant
At tax time or in a cash flow review you want to export or share a report, not reconstruct the position from a dozen email threads. Check that the export exists before you need it.
How Billbooks handles receivables
What is actually in the product
Being specific about what Billbooks includes, rather than what the category can mean: every paid plan has automatic past-due reminders at intervals you set, invoice open alerts that tell you when a client has viewed an invoice, an Outstandings Report showing which clients carry the most outstanding balance, and a Collections Report summarising payments received. Those sit alongside the invoice, sales, expense, profit and loss and sales tax reports.
What is not there, said plainly
Billbooks does not have a bucketed accounts receivable aging report of the kind QuickBooks and FreshBooks ship, where invoices are grouped into 1 to 30, 31 to 60 and 61 to 90 day columns. The Outstandings Report answers who owes the most, not how the debt is distributed by age. If a formal aging schedule is something your accountant asks for by name, that is a real gap and worth knowing before you sign up rather than after.
What it costs
Basic is 7.95 dollars a month for 2 users, 100 clients and unlimited invoices and estimates. Standard is 14.95 for 5 users and 500 clients. Professional is 29.95 for 10 users and unlimited clients. Every plan includes every core feature, so the higher tiers mainly add capacity, with Xero and Zapier on Professional, and the AR features above are in all of them. There is a 30-day trial with no card required.
The other half of that, which the Billbooks pricing page states itself: there is no permanently free tier, and Wave, Zoho Invoice, Square Invoices and PayPal Invoicing all offer one. If a zero monthly cost is the requirement, start there instead.
Every unpaid invoice, its age and its status
See what is outstanding per client, let the reminders go out on their own, and export the report when your accountant asks. Try Billbooks free for 30 days, no card.
Matching the tool to your invoice volume
A solo freelancer with a handful of clients needs reliable automatic reminders and a clear view of who still owes what, which is already inside invoicing software at a freelancer price. A small team billing more customers gets real value from the reporting and the extra seats. Full AR automation earns its keep only once matching payments by hand is itself a part-time job.
Match the tool to the number of invoices you send each month, not to the longest feature list you can find. If you are still deciding what terms to set in the first place, our note on 2/10 net 30 covers the trade-off, and there are practical payment reminder templates and a guide to recovering outstanding invoices for the invoices that have already gone quiet.
FAQ
What is accounts receivable software?
It is software that tracks money owed to a business by its customers, automates reminders on unpaid invoices, and reports on how much is outstanding and for how long. Many invoicing tools include the same functions without using the accounts receivable label.
What is an accounts receivable aging report?
It is a report that groups unpaid invoices by how overdue they are, conventionally current, 1 to 30 days, 31 to 60, 61 to 90, and 91 and over. QuickBooks publishes both a summary version by customer and a detail version listing each transaction, and the 30-day interval can be changed.
Do freelancers need dedicated accounts receivable software?
Usually not. The tracking and automatic reminders built into invoicing software cover what most freelancers need. Dedicated AR platforms earn their cost at the point where manually matching incoming payments to invoices takes hours every week.
How common are late payments for small businesses?
Common enough to plan for. In a January 2025 Intuit QuickBooks survey of 2,487 US small businesses, 56 percent were owed money on unpaid invoices, averaging 17,500 dollars each, and 47 percent had invoices more than 30 days overdue.
What is the difference between accounts receivable software and invoicing software?
Invoicing software is about creating and sending the invoice. Accounts receivable is about everything after it is sent: payment status, automated follow-up, and reporting on what is still owed. In small business tools the two are usually the same product.
Does Billbooks have an accounts receivable aging report?
Not as a bucketed aging schedule. Billbooks has an Outstandings Report showing which clients carry the most outstanding balance, a Collections Report for payments received, plus automatic past-due reminders and invoice open alerts on every paid plan. If your accountant needs a formal aging report by age band, that is a gap worth checking before you commit.
