The AR Agent

Best accounts receivable software for small business

· 12 min read

The best accounts receivable software depends on what part of AR is actually causing you problems.

If you only need automatic invoice reminders, the tools already inside QuickBooks or Xero may be enough.

If you need structured collections workflows, customer payment portals and reporting, platforms such as Chaser and Upflow go further.

If the real problem is everything that happens after a customer replies, such as tracking payment promises, identifying missing POs, dealing with disputes and deciding what to do next, you need software that handles more than scheduled reminders.

This guide compares the main options and who each one is best suited to.

The best AR software at a glance

Software Best for Main strength
QuickBooks Online Small businesses already using QuickBooks Built-in invoicing and reminders
Xero Small businesses already using Xero Simple automated invoice reminders
Chaser SMBs wanting dedicated credit control Collections automation and payment chasing
Upflow Growing B2B finance teams Collections, payments and AR analytics
Kolleno More complex finance teams Broad AR automation and workflow management
Gaviti Larger AR teams Invoice-to-cash automation
The AR Agent Service businesses where chasing and replies consume time AI handling of overdue invoice conversations and next actions

There is a meaningful difference between these categories.

You probably do not need a full invoice-to-cash platform if you send 20 invoices a month.

Equally, three scheduled reminders may not be enough if you have hundreds of outstanding invoices and customers constantly replying with questions and payment promises.

1. QuickBooks Online

Best for: Small businesses already using QuickBooks that mainly need invoicing, aging reports and automatic reminders.

QuickBooks Online already covers a surprising amount of basic accounts receivable work.

Businesses can create invoices, monitor receivables, run AR aging reports and configure automatic invoice reminders before or after the due date.

Where QuickBooks works well

If you are a small business with relatively straightforward collections, staying inside the accounting software you already use has obvious advantages.

You can:

  • Create and send invoices.
  • Track whether invoices are paid.
  • Review accounts receivable aging.
  • Send manual reminders.
  • Set automatic reminders.
  • Generate customer statements.

There is no need to add another system just because one or two invoices occasionally become overdue.

Where you may outgrow it

Scheduled reminders work well when the next step depends mainly on the invoice date.

Collections gets more complicated when the customer replies.

For example:

We'll pay Friday.

We need a PO number.

This invoice isn't correct.

Please send this to accounts payable.

At that point, someone still needs to read the reply, work out what it means, record the next action and make sure it actually happens.

Best choice if: You already use QuickBooks and your collections process is still simple.

2. Xero

Best for: Small businesses already using Xero that want simple automated payment reminders without adding another platform.

Xero also includes automatic invoice reminders.

Where Xero works well

It is a sensible starting point if your problem is:

We're forgetting to remind people to pay.

You can configure a schedule, customize the wording and let Xero handle straightforward reminders.

For many very small businesses, that may be enough.

Where you may outgrow it

The same limitation applies as with most reminder systems.

The customer response creates the work.

Once somebody tells you there is a dispute, missing PO or payment date, collections stops being a simple scheduled-email problem.

Best choice if: You use Xero and want to automate basic reminders before buying dedicated AR software.

3. Chaser

Best for: Small and midsize businesses that want a dedicated credit control and invoice-chasing platform.

Chaser focuses much more directly on accounts receivable and credit control.

Its current product includes automated payment reminders, payment behavior tracking, payment options, receivables management, disputed invoice handling, payment plans and customer notes.

Where Chaser works well

Chaser is worth looking at when someone in your business is spending a meaningful amount of time actively managing overdue invoices.

Features include:

  • Automated chasing.
  • Customer and invoice management.
  • Payment links and payment portal functionality.
  • Payment plans.
  • Notes and reminders.
  • Disputed invoice tracking.
  • Customer payment behavior information.

It is particularly relevant for finance teams that think of the problem as credit control, which is common terminology in the UK.

What to consider

Think about how much complexity you actually need.

A dedicated collections platform gives you more control than a few accounting-system reminders, but it also becomes another part of your finance stack.

Best choice if: You want a specialist credit control platform rather than relying on QuickBooks or Xero reminders.

4. Upflow

Best for: Growing B2B companies that want collections automation plus payment tools and stronger AR reporting.

Upflow combines collections workflows with AR analytics, customer payment functionality and cash application tools.

Where Upflow works well

Upflow becomes more relevant when AR is no longer just one person's invoice-chasing list.

The platform is designed around things such as:

  • Multi-step collections workflows.
  • Segmentation based on customer behavior.
  • AR reporting.
  • Customer payment portals.
  • Payment promises.
  • Collaboration between finance and other teams.
  • Cash application.

That broader scope can make sense for a growing finance organization.

What to consider

If you are a very small service business and your main problem is simply the time spent chasing 30 overdue invoices, you may not need every part of a broader AR platform.

Best choice if: AR is becoming a real finance function and you want collections, reporting and payments in one system.

5. Kolleno

Best for: Finance teams wanting broad accounts receivable automation across collections, reconciliation, reporting and credit processes.

Kolleno has expanded beyond simple collections automation into a broader AR platform.

Where Kolleno works well

Kolleno is designed for finance teams that need more than invoice reminders.

Its functionality includes:

  • Automated collections workflows.
  • Customer and invoice-level processes.
  • Payment plans.
  • Cash application and reconciliation.
  • AR analytics.
  • Credit risk tools.
  • ERP integrations.
  • AI-assisted actions and analysis.

What to consider

Breadth can be valuable, but small businesses should decide whether they actually need it.

If your current process is one finance manager, QuickBooks and Gmail, a large AR transformation project may be more software than the problem requires.

Best choice if: Your collections process is becoming operationally complex and you want a broader AR platform.

6. Gaviti

Best for: More established finance teams wanting invoice-to-cash automation.

Gaviti positions itself as a broader invoice-to-cash platform.

Its current product covers collections automation, customer payment functionality, credit and risk management and cash application.

Where Gaviti works well

It may make sense if your accounts receivable operation includes several connected problems:

  • Collections.
  • Payment processing.
  • Cash application.
  • Credit management.
  • Team prioritization.

That is a different requirement from a five-person agency whose founder wants to stop manually emailing late-paying clients.

What to consider

As with Kolleno, the question is whether you need a full AR platform or a narrower collections solution.

Best choice if: You have an established finance team and want to automate a larger part of the invoice-to-cash cycle.

7. The AR Agent

Best for: Service businesses where the painful part is not sending reminders, but dealing with everything that happens after them.

The AR Agent is an AI accounts receivable and collections agent.

It works with QuickBooks, Xero, Gmail and Outlook.

Rather than replacing your accounting system, it handles overdue invoice follow-up around it.

Where The AR Agent is different

Basic invoice reminder tools work like this:

Invoice becomes seven days overdue → send reminder.

The AR Agent is designed around what happens next.

If the customer replies:

We'll pay Friday.

The payment promise can be tracked and followed up if it is missed.

If they say:

We need a PO number.

That becomes a blocker rather than triggering another generic reminder.

If they say:

There's a problem with the invoice.

Normal chasing pauses.

If the agent reaches something that genuinely needs human judgment, it asks rather than guessing.

It also keeps the emails, payment promises, blockers and actions together against the invoice and customer.

What it does not try to replace

The AR Agent is not an accounting system.

It does not replace QuickBooks or Xero.

It also does not process payments, factor invoices, provide lending or act as a collection agency.

The purpose is narrower:

Get paid without doing the chasing.

Best choice if: Your business already has invoicing and accounting sorted, but somebody is still spending hours every week following up unpaid invoices and dealing with the replies.

What features should small businesses actually look for?

Feature lists can make every AR platform look the same.

Instead, ask what the software needs to remove from your day.

Accounting integration

Start here.

If you use QuickBooks or Xero, the software should work cleanly with it.

You do not want finance maintaining two conflicting lists of outstanding invoices.

Automated reminders

This is the baseline.

You should be able to follow up invoices based on due dates without manually checking a spreadsheet every morning.

Reply handling

Ask:

What happens when the customer answers?

This is an important distinction.

If the software sends an email but the reply lands with you and creates another manual task, only part of the workflow has been automated.

Payment promise tracking

"We'll pay Friday" should become a tracked date.

If Friday passes without payment, something should happen.

Dispute handling

A genuine invoice dispute should stop standard chasing.

Sending another automated reminder while the customer is waiting for you to correct an invoice is bad collections and bad customer service.

Blocker tracking

Look for a way to record why an invoice is not being paid.

For example:

  • Missing PO.
  • Wrong contact.
  • Waiting for approval.
  • Invoice query.
  • Cash flow problem.
  • Payment promised.

"Overdue" alone is not enough information.

Aging and prioritization

You should be able to see which balances need attention.

An accounts receivable aging report is the natural starting point.

More sophisticated tools can then help prioritize based on amount, age, customer behavior or risk.

Human control

Automation should not mean giving software permission to improvise in every situation.

Sensitive customers, disputes and unusual situations still need judgment.

Look at what the system does when it is uncertain.

How much AR software do you actually need?

A simple rule is:

Stay with QuickBooks or Xero if:

  • Invoice volume is low.
  • Most customers pay without much chasing.
  • Automatic reminders solve most of the problem.
  • You rarely deal with disputes or complicated replies.

Consider dedicated collections software if:

  • Someone spends hours every week chasing invoices.
  • Invoices regularly fall through the cracks.
  • You have enough customers that spreadsheets are becoming difficult.
  • You need more reporting and control over collections workflows.

Consider broader AR automation if:

  • You have a dedicated AR team.
  • Collections spans several people or entities.
  • Cash application is also a major workload.
  • You need credit risk management.
  • Your finance stack includes an ERP and other connected systems.

Consider an AI AR agent if:

  • Reminder automation is not the real problem.
  • Your team spends time reading and responding to customer emails.
  • Payment promises are regularly forgotten.
  • Missing POs, invoice queries and wrong contacts slow collections down.
  • You want routine chasing handled but still want a person involved when judgment is needed.

Basic reminders vs collections software vs an AR agent

Level What it mainly solves Example
Invoice reminders Remembering to email QuickBooks, Xero
Collections software Structuring and managing collections Chaser, Upflow
Broader AR platforms Collections plus payments, reconciliation, credit or analytics Kolleno, Gaviti
AI AR agent Acting on overdue invoices and customer replies The AR Agent

The categories overlap.

Modern AR platforms are increasingly adding AI, while accounting systems continue adding automation.

So do not buy software based on a label.

Look at the workflow you want to remove.

Questions to ask before choosing AR software

Before booking five demos, answer these:

  1. How many invoices do we send each month?
  2. How many are usually overdue?
  3. Who currently chases them?
  4. How many hours does that take?
  5. What actually consumes the time: sending emails or dealing with replies?
  6. Which accounting system do we use?
  7. Do we need payment processing as well?
  8. Do we need cash application?
  9. Do we have a dedicated AR team?
  10. What decisions still need a human?

Your answers will eliminate half the market immediately.

Frequently asked questions

What is accounts receivable software?

Accounts receivable software helps businesses manage money owed by customers. Depending on the product, that can include invoicing, aging reports, payment reminders, collections workflows, customer communications, payment portals, cash application, reporting and credit management. Some products cover one part of AR, while larger platforms cover most of the invoice-to-cash process.

Does QuickBooks have accounts receivable software?

Accounts receivable functionality is built into QuickBooks Online. It can create invoices, track outstanding balances, produce AR aging reports and send automatic or manual invoice reminders. For businesses with straightforward collections, that may be enough. More complex collections processes may benefit from dedicated software connected to QuickBooks.

Does Xero automatically chase unpaid invoices?

Xero can send automated invoice reminders before or after an invoice due date. Businesses can configure the reminder schedule and turn reminders off for specific customers or invoices. If customers frequently reply with disputes, payment promises or other issues, somebody still needs to manage what happens after the reminder.

When does a small business need dedicated AR software?

Usually when managing receivables is becoming a recurring workload rather than an occasional admin task. Signs include significant time spent chasing, invoices being forgotten, payment promises not being tracked, growing overdue balances and multiple people needing visibility into customer conversations.

What is AR collections software?

AR collections software focuses specifically on collecting outstanding invoices. Typical features include automated reminders, collections workflows, customer segmentation, aging views, payment tracking, notes, escalations and reporting. Some newer platforms also include payments, cash application, credit risk and AI functionality.

Can AI automate accounts receivable collections?

Parts of it, yes. AI can help with tasks beyond fixed reminder schedules, including understanding customer replies, identifying common blockers and deciding which routine action should happen next. Human oversight still matters for disputes, sensitive customer situations and decisions requiring commercial judgment.

How The AR Agent handles this

The AR Agent is designed for businesses that already have an accounting system but still do the collections work manually.

It follows up overdue invoices by email, reads customer replies and tracks what should happen next. Payment promises become tracked commitments. Missing POs and wrong contacts become blockers. Disputed invoices stop normal chasing.

When something genuinely needs human judgment, it asks rather than guessing.

The result is not another accounting system or payment platform. It is an agent focused on the work between invoice overdue and invoice paid.
