Short answer: "Accounts receivable software" returns three products that are not substitutes for each other. One is an AR automation platform that chases invoices you have already issued (Chaser, Upflow, Gaviti, Versapay, Billtrust, HighRadius). One is a payments suite that bundles AR with accounts payable in the same seat licence (BILL). One is debt collection agency software, built for third party collectors and irrelevant to an in house finance team. Most buyers waste the first two demos finding that out.
The second thing to know is that entry prices are not comparable, because almost nobody charges per user. Chaser prices by your annual revenue band. Upflow prices by gross invoice value and invoice count. BILL prices per user per month. Billtrust and Versapay publish nothing at all. Two companies with identical receivables can get quotes that differ by an order of magnitude, and neither quote is wrong.

Three products share one search term
Roundup articles list Billtrust next to BILL next to SimplicityCollect as though you would shortlist all three. You would not. They sit in different places in the invoice to cash chain and get bought by different people.
| AR automation platform | AP and AR suite | Collection agency software | |
|---|---|---|---|
| Examples | Chaser, Upflow, Gaviti, Versapay, Billtrust, HighRadius, Esker | BILL, Melio | SimplicityCollect, CollectMax |
| What it does | Chases open invoices, runs reminder workflows, applies cash, manages disputes | Issues invoices and pays bills from one ledger | Manages third party debt placements, compliance, commission splits |
| Who buys it | Controller or AR manager at a B2B company | Owner or bookkeeper at a small business | A collections agency, not the original creditor |
| Sits on top of | Your ERP or accounting system | Replaces the AP and AR side of it | Nothing you own |
| Published pricing | Mostly no | Yes | Mostly no |
If you invoice other businesses on terms and your problem is that customers pay late, you want the first column. That is the category this guide is about. The accounts receivable process it automates is the same one you already run by hand: issue, deliver, remind, escalate, apply cash, close.
Verified pricing, September 2026
Only two of the seven vendors below publish a number you can act on. That is not an accident. AR platforms price on the size of your receivables, so a published price would be misleading for most of the market. It also means the figures in software directories are frequently stale, and in one case here they are off by more than six times.
| Vendor | Published price | What the price is based on |
|---|---|---|
| Chaser | Compact $259, Core $779, Complete $1,169 per month (USD) | Annual revenue band. Compact covers under $5M revenue and caps you at 4 users. Core and Complete are unlimited users. |
| BILL | Essentials $49, Team $65, Corporate $89 per user per month | Per user. AP and AR are bundled on every tier and cannot be bought separately. |
| Upflow | Subscription is quote only. Upflow Payments add on is $390 per month plus 3.5% and $0.30 on cards, 0.8% capped at $5 on ACH. | Gross invoice value and invoice count. Starter covers up to $10M GIV and 40,000 invoices a year; Enterprise covers over $100M and 700,000 invoices. Seats are unlimited on every tier. |
| Gaviti | None published | The vendor states pricing is "based on your usage, not per user." |
| Invoiced | None published | Quote only since the Flywire acquisition. Directories still publish a $500 per month plan and a 1% of invoices issued model. The vendor's own page shows neither. |
| Versapay | None published | No pricing page exists. The URL returns a 404. |
| Billtrust | None published | No pricing page exists. Directories publish a "$65 per month" starting price while stating in the same listing that pricing is not disclosed. Treat that number as unverified. |
The Chaser figure is worth pausing on, because it is the clearest example of why you should check the vendor's own page before you budget. Several directories still list Chaser as starting at $40 a month. The vendor's published USD price for its entry tier is $259 a month, and that tier stops at four users and $5M in annual revenue. If you had built a business case on the directory number you would be six times short before the first call.
The billing unit is the variable that decides your invoice
Headline rates in this category are close to meaningless on their own, because no two vendors measure the same thing. Work out which unit each quote is denominated in before you compare anything.
| Billing unit | Who uses it | What makes your bill go up |
|---|---|---|
| Annual revenue band | Chaser | Growing, even if your invoice count and AR workload stay flat |
| Gross invoice value plus invoice count | Upflow | Invoicing more, or invoicing larger amounts |
| Per user per month | BILL | Adding finance headcount |
| Per module plus implementation | Billtrust, Versapay, HighRadius, Esker | Turning on cash application, disputes or credit risk as separate line items |
| Percentage of invoices issued | Legacy Invoiced contracts | Every invoice, regardless of whether it was paid on time |
The practical consequence: a company doing $8M in revenue on 400 large invoices a year and a company doing $8M on 40,000 small ones are the same customer to a revenue band model and completely different customers to a volume model. Pick the model that matches your shape, not the one with the lowest advertised entry price.
What accounts receivable software actually does
Six capabilities show up on every vendor's feature list. They are not equally mature, and the last two are where the mid market and enterprise platforms actually earn their price.
| Capability | What it replaces | Where it usually falls short |
|---|---|---|
| Invoice delivery and tracking | Emailing PDFs and hoping they arrived | Nothing much. This works everywhere. |
| Automated reminder workflows | A spreadsheet of who to chase this week | Tone. Default templates read like a collections notice from day one. |
| Customer payment portal | Customers calling to ask for a copy of an invoice | Branding limits, and portals that require your customer to create an account. |
| Cash application | Manually matching bank deposits to open invoices | Short payments, lump sum remittances and missing remittance advice. |
| Dispute and deduction handling | Email threads nobody can find later | Weak on the accounting side. Many tools log the dispute but cannot post the credit. |
| Credit risk and forecasting | Judgement calls about who to put on hold | Thin data on private companies, so scores lean on your own payment history. |
Cash application is the capability that separates a genuinely useful platform from an expensive email scheduler. When a customer sends one payment covering nine invoices and shorts two of them, somebody has to reconcile that. Teams that solve this outside their AR platform usually end up doing it in a spreadsheet or in a dedicated reconciliation tool that matches bank and processor lines to open items, which works, but it means the AR platform is no longer the system of record for what is actually outstanding.
Do you need it, or is your accounting system enough?
QuickBooks, Xero and NetSuite all include AR. They issue invoices, track what is open, and produce an aging report. For a lot of companies that is sufficient, and buying a platform on top of it is the wrong fix.
The honest test is whether your problem is visibility or follow up. If you cannot tell who owes you what, your accounting system already solves that and you have a data hygiene problem, not a software gap. If you can see exactly who is late and nobody has time to chase them consistently, that is what AR automation is for. The tell is a DSO that sits well above your stated terms while your aging report is accurate.
Two other signals point to a platform being worth it. One is a collections process that lives in one person's head or inbox, which breaks the moment that person takes a holiday. The other is customers who genuinely do not receive invoices, usually because they route through an AP portal that your accounting system cannot submit to. Neither of those gets fixed by writing better past due invoice emails.
Matching a tool to your receivables profile
Four questions narrow the field faster than any feature matrix.
- How many open invoices do you carry at once? Under a few hundred, reminder automation inside your accounting system or a low tier tool covers it. Over a few thousand, you need real segmentation and workflow.
- What is your average invoice value? High value, low volume receivables reward relationship features: dispute tracking, promise to pay logging, escalation paths. High volume, low value receivables reward automation and self service.
- Do your customers pay through their own AP portals? If a meaningful share do, portal submission support moves from nice to have to a hard requirement, and it eliminates most of the lightweight tools immediately.
- Who owns the chase? If it is finance, buy for workflow. If account managers are expected to raise payment with their own clients, buy for the notification and visibility features instead, because a tool nobody outside finance logs into will not change behaviour.
If your receivables are recurring rather than project based, look at subscription billing and recurring revenue tools before AR platforms. Failed card payments are a different problem with a different fix, and general AR automation handles them badly.
Five things to test in an AR software demo
- Bring your own messy remittance. Ask the vendor to apply a real lump sum payment that covers several invoices and short pays one. Watch whether a human has to intervene. This is the demo most vendors would rather skip.
- Ask what happens when the ERP sync fails. Integration is where AR projects stall. You want to know whether a failed sync is visible, queued and retryable, or silently dropped.
- Read the default reminder templates out loud. They go to your customers under your name. If the first reminder sounds like a legal notice, you will spend months rewriting the sequence, and there is a real difference between dunning and collections that most default templates ignore.
- Ask for the price at double your current volume. Given the billing units above, this is the single most useful question in the call. It tells you what growth costs and it flushes out revenue band cliffs.
- Ask who does the implementation and how long it takes. On the enterprise platforms, implementation is a separate line item and frequently exceeds the first year subscription.
Mistakes that make AR software cost more than it saves
The most common one is buying for collections and never turning on cash application, which leaves the team doing the tedious half of the job manually while paying for a platform that could do it. The second is running the tool as a parallel system to the ERP, so the aging report in the platform and the aging report in the general ledger disagree and nobody trusts either.
The third is treating AR software as a replacement for a policy. A tool will send reminders on a schedule, but it will not decide when an account goes on credit hold, who can approve an exception, or what happens at 90 days. Write that down first. Automating an undefined process just makes the inconsistency faster.
The fourth is scoping AR in isolation. If you are also fixing the payables side, note that accounts payable automation is a separate market with separate vendors, and only the small business suites credibly do both. A search for "accounts payable and receivable software" mostly returns tools that are strong at one and thin at the other.
Questions buyers ask
What software is used for accounts receivable?
Most companies use the AR module in their accounting system or ERP, such as QuickBooks, Xero, Sage or NetSuite. Companies with a collections problem add a dedicated AR automation platform on top, most commonly Chaser or Upflow at the small and mid market end, and Versapay, Billtrust, HighRadius or Esker at enterprise scale.
How much does accounts receivable software cost?
Published entry pricing runs from $49 per user per month for a bundled AP and AR suite to $259 per month for a dedicated AR platform at the smallest revenue band. Mid market and enterprise platforms do not publish pricing at all and quote against your receivables volume, module selection and implementation scope.
Do you need accounts receivable software if you already use QuickBooks?
Not usually, unless follow up is the bottleneck. QuickBooks issues invoices, tracks what is open and produces an aging report. You need a platform on top when chasing is inconsistent, when you carry thousands of open invoices, or when customers require submission through their own AP portals, which QuickBooks cannot do.
What is the best accounts receivable software for small business?
For a small business already invoicing from QuickBooks or Xero, a bundled suite like BILL at $49 to $89 per user per month is usually the practical choice, because it covers payables in the same licence. A dedicated AR platform makes sense earlier if you are B2B, on terms, and carrying hundreds of overdue invoices.
Does accounts receivable software actually reduce DSO?
It reduces the part of DSO caused by inconsistent follow up, which is often several days. It does nothing about the part caused by your payment terms, your customers' own approval cycles, or invoices that are disputed on delivery. Measure your receivables turnover before and after so you know which part moved.
Where to start
Pull your current aging report and count two numbers: how many invoices are past due, and how many of those are past due because nobody chased them rather than because the customer disputed something. If the first number is large and the second is mostly "nobody chased," an AR platform will pay for itself quickly. If most of your overdue balance is disputed or blocked in a customer portal, fix that first, because automation will only send reminders into a void faster.
Then ask every vendor the same two questions: what unit am I being billed in, and what does this cost at double my volume. In a market where five vendors use five different units and four of them publish nothing, that pair of questions does more work than any feature comparison.
