The best AR automation software helps small businesses create invoices, accept payments, send reminders, track overdue balances, and record transactions without relying on spreadsheets or repeated data entry. Some products combine these tools with accounting software, while others focus on collections, cash application, or subscription billing.

I evaluated seven SMB-oriented invoicing platforms and accounts receivable tools using a weighted rubric I developed around pricing, core AR features, ease of use, customer support, advanced automation, and overall value. I excluded enterprise-first products with high implementation costs, long sales cycles, or feature sets that most small businesses are unlikely to need.

My top picks for best accounts receivable automation software for small businesses are:

*QuickBooks Payments has no separate monthly payment processing fee, but the integrated AR workflow reviewed here generally uses a QuickBooks plan. QuickBooks Online Simple Start is listed at $38 per month before temporary discounts, and transaction fees apply.

What is accounts receivable automation software?

Accounts receivable automation software reduces manual work between creating a customer invoice and recording the payment. Depending on the product, it can automate invoice generation, recurring billing, payment reminders, online payment acceptance, payment matching, collections workflows, customer statements, and cash flow reporting.

  • Creates and sends invoices
  • Schedules recurring invoices
  • Sends payment reminders
  • Accepts online payments
  • Matches payments to invoices
  • Tracks overdue accounts
  • Supports collections workflows
  • Reports on cash flow and DSO

Basic invoicing platforms usually focus on invoice creation, payment links, and reminders. Dedicated AR tools may also include customer portals, collections queues, promise-to-pay tracking, cash application, and overdue account prioritization.

Automatic invoicing uses rules or schedules to create, send, and follow up on invoices with limited manual work. It can help businesses bill customers consistently and keep payment records current.

Common examples include recurring monthly invoices, scheduled invoice delivery, saved payment methods, automatic reminders, payment matching, and accounting updates.

Automatic invoicing is especially useful for retainers, maintenance contracts, memberships, subscriptions, and other repeat billing arrangements.

AR automation can help small businesses send invoices consistently, offer easier payment options, reduce repetitive follow-up, identify overdue balances, match payments faster, and keep accounting records current.

Key benefits include:

  • Faster invoice delivery
  • Easier customer payments
  • Less manual follow-up
  • Better overdue balance tracking
  • Faster payment matching
  • More consistent collections
  • Clearer short-term cash visibility

The results still depend on accurate invoices, clear payment terms, and reliable customer data. AR software cannot resolve invoice disputes, weak credit policies, or customers who are unable to pay.

I evaluated seven platforms using a 22-point weighted rubric developed for small businesses. Each provider received a score for every subcriterion based on official US pricing, feature, and support documentation. I then applied the assigned category weights to calculate a final score out of 5.

The rubric gives added weight to ease of use and essential accounts receivable workflows, as many small businesses lack dedicated IT teams or accounts receivable departments. Advanced enterprise features received less weight unless they offered clear value to an SMB. Pricing or product information that was unavailable or unclear received a lower score for transparency.

Below is the breakdown of my evaluation criteria.

  • Pricing (20%): I evaluated entry-level affordability, pricing transparency, free plans or trials, and transaction and add-on costs. Providers scored higher when they published clear prices, offered low-cost access, avoided high implementation fees, and provided flexible terms suitable for small business budgets.
  • General features (25%): I reviewed invoice creation and delivery, online payment acceptance, automated reminders and follow-ups, customer portals and payment tracking, and accounting integrations and reconciliation. Providers scored higher when they covered the full invoice-to-payment workflow and reduced manual data entry.
  • Advanced features (10%): I reviewed collections automation, customer payment portals, cash application, cash flow forecasting, analytics, artificial intelligence, subscription dunning, and other higher-level receivables tools. Providers scored higher when these features reduced manual collection work without creating an excessive setup burden.
  • Ease of use (25%): I assessed initial setup, day-to-day usability, interface and navigation, and available onboarding resources. Providers scored higher when a business owner or small finance team could set up and operate the software without specialized technical support.
  • Customer support (10%): I evaluated the available support channels, service hours, and self-help resources, including knowledge bases, tutorials, and community forums. Providers scored higher when customers could reach support through several channels and access clear documentation.
  • Expert score (10%): I separately evaluated feature quality, value for money, market reputation, product transparency, and overall suitability for small businesses. I considered official provider information, available hands-on experience, product research, integrations, and third-party user feedback.

I have more than seven years of experience evaluating point-of-sale systems, payment processors, accounting tools, and retail software. My hands-on work includes testing payment apps, invoicing tools, payment links, online checkout flows, mobile card readers, Tap to Pay features, and other workflows businesses use to bill customers and collect payments.

For this guide, I reviewed official pricing pages, product documentation, help centers, and support resources, along with available product testing, demos, and third-party user feedback. I focused on how well each platform supports invoicing, payment collection, reminders, tracking, reconciliation, accounting integrations, and practical use for small businesses.

Pros

  • Payments and invoices connect directly with QuickBooks accounting
  • Supports cards, ACH, PayPal, Venmo, Apple Pay, and in-person payments
  • Tracks when customers view and pay invoices
  • Automatically records online payments in QuickBooks Online
  • Offers recurring invoices and automated reminders

Cons

  • Payment processing fees apply
  • Advanced recurring billing features can depend on the QuickBooks plan
  • It has fewer collections-management tools than Upflow or Centime
  • Merchant approval is required to process payments

Why I chose QuickBooks Payments

QuickBooks Payments is my top choice for small businesses that already use QuickBooks or want invoicing, payments, and accounting in one system. It supports online and recurring invoices, automated payment reminders, real-time invoice tracking, and automatic payment recording in QuickBooks Online. Customers can pay using credit and debit cards, ACH, Apple Pay, PayPal, or Venmo, making it a practical choice for businesses with multiple payment channels.

QuickBooks Payments streamlines the entire accounts receivable process, from creating and sending invoices to accepting payments and reconciling transactions. That seamless workflow earned it the highest ease-of-use score in my rubric because it minimizes manual data entry and reduces the need for separate invoicing or payment software, making it an excellent fit for most small businesses.

When QuickBooks Payments may not fit: Your business needs advanced collections prioritization, detailed DSO and collections reporting, multi-ERP support, subscription dunning, usage-based billing, or a standalone accounts receivable platform that doesn’t rely on QuickBooks.

QuickBooks Online monthly software fees:

  • Simple Start: $38 for one user
  • Essentials: $75 for three users
  • Plus: $115 for five users
  • Advanced: $275 for 25 users

**New customers can choose between 50% off for three months or a 30-day free trial.

The Simple Start plan supports recurring invoice scheduling, but recurring invoices are not the same as automatic customer charges. QuickBooks can send the invoice on schedule, but the customer must pay it or choose Autopay. 

For this guide, Essentials and higher tiers are the relevant plans for evaluating recurring invoice workflows. Automatic recurring charges require an active QuickBooks Payments or Merchant Services account; Essentials does not include QuickBooks Payments by itself. 

QuickBooks Payments

  • No monthly subscription fee, setup fee, or monthly processing minimum
  • Requires an approved QuickBooks Payments or Merchant Services account
  • Requires a QuickBooks Online subscription for the recurring payment workflow
  • Processing fees apply to each payment

Processing rates:

  • Bank payments: 1%
  • Online card and digital wallet payments, including recurring payments: 2.99%
  • Card reader payments: 2.5%
  • Keyed-in card payments: 3.5%
  • Instant deposits: An additional 1.75%

  • Automatic invoicing: QuickBooks supports scheduled recurring invoices and recurring customer billing on eligible plans. 
  • Automated reminders: Users can follow up on unpaid invoices with custom payment reminders. QuickBooks is also promoting a Payments Agent that monitors payment patterns and helps draft reminders.
  • Online payments: Customers can pay through an invoice using cards, ACH, PayPal, Venmo, or Apple Pay.
  • Payment tracking: QuickBooks shows when an invoice has been sent, viewed, and paid. 
  • Automatic bookkeeping: Online payments are recorded in QuickBooks Online, reducing manual transaction entry.
  • Recurring payments: Businesses can automatically charge customers according to a set schedule.

Pros

  • Free plan for qualifying small businesses
  • Recurring invoices and automatic reminders on all plans
  • Built-in customer portal
  • Supports online and recurring payments
  • No long-term contract requirement

Cons

  • Free plan has revenue and invoice limits
  • Online payment processing may require a connected payment gateway
  • Advanced automation and forecasting require higher plans
  • Businesses using QuickBooks would need to change accounting systems or operate both products

Why I chose Zoho Books

Zoho Books combines accounting, invoicing, online payments, reminders, recurring invoices, and a customer portal at a low entry price. Its free plan supports one user and one accountant, is available to US businesses with annual revenue of no more than $50,000, and allows up to 1,000 invoices per year.

I chose Zoho Books for businesses that need more than a basic invoice generator but are not ready to pay for a dedicated AR platform. It scored just 0.02 points below QuickBooks Payments, performing better on pricing while trailing on ease of use and its payment-to-accounting workflow.

When Zoho Books may not fit: Your business already relies on QuickBooks, needs dedicated collection queues, requires cash application or advanced subscription billing, or expects to outgrow the free plan’s revenue and invoice limits.

Related: Best Accounting Software for Business

  • Free: $0
  • Standard: $20 monthly, or $15 monthly billed annually
  • Professional: $50 monthly, or $40 monthly billed annually
  • Premium: $70 monthly, or $60 monthly billed annually
  • Elite: $150 monthly, or $120 monthly billed annually
  • Ultimate: $275 monthly, or $240 monthly billed annually

The free plan includes one user and one accountant. Paid plans increase user and invoice limits, with additional users available as an add-on. Payment gateway fees are separate from the Zoho Books subscription.

  • Recurring invoices: Included across Zoho Books plans.
  • Payment reminders: Automated reminders are available on every listed plan.
  • Customer portal: Customers can view statements, make partial or bulk payments, and review transaction details. 
  • Online payments: Businesses can accept invoice payments, send payment links, and automatically charge recurring invoices through supported payment services. 
  • Bank reconciliation: Included in the free plan. 
  • Cash flow forecasting: Available beginning with the Zoho Books Premium plan.

Pros

  • Combines accounts payable and receivable functions
  • Supports recurring invoices and automated reminders
  • Accepts ACH and card payments
  • Offers auto-charge and autopay
  • Two-way accounting sync on eligible plans

Cons

  • Per-user pricing can become expensive
  • Automatic accounting sync requires at least the Team plan
  • Payment transaction fees may apply
  • More setup and administration than QuickBooks Payments or Zoho Books

Why I chose BILL

BILL is a strong fit for growing companies that want accounts payable and accounts receivable tools in one platform. Its AR features include invoice creation, scheduled and recurring invoices, automated reminders, payment tracking, ACH and card acceptance, auto-charge, and autopay.

I chose BILL for small businesses moving from owner-managed bookkeeping to a more structured finance operation. It supports two-way synchronization with QuickBooks Online, QuickBooks Pro, QuickBooks Premier, and Xero on the Team plan and above, making it a practical step up for teams adding finance staff or formal approval controls.

When BILL may not fit: Your business is a freelancer or sole proprietorship, has low invoice volume, only needs payment links, does not need AP automation, or cannot justify per-user pricing and a higher-tier plan for automatic two-way accounting sync.

BILL lists the following direct-customer AP and AR plans:

  • Essentials: $49 per user monthly
  • Team: $65 per user monthly
  • Corporate: $89 per user monthly
  • Enterprise: Custom pricing

The Team plan adds automatic two-way synchronization with QuickBooks Online, QuickBooks Pro, QuickBooks Premier, and Xero. BILL says AP and AR subscriptions are paid products, although a free trial is available in most cases. Transaction fees may apply for certain payment methods.

  • Custom invoice templates
  • Scheduled and recurring invoices
  • Invoice status tracking
  • Automated payment reminders
  • ACH and card acceptance
  • Auto-charge and autopay
  • Two-way accounting synchronization
  • Combined AP and AR management

Pros

  • Full collections and payment workflow
  • AI-assisted collections
  • Customer portal with autopay
  • Cash flow forecasting
  • Supports all versions of QuickBooks
  • Pricing is based on invoice volume rather than users

Cons

  • Quote-based pricing
  • Standard implementation fee
  • Seven- to 21-day implementation period
  • Product positioning leans toward mid-market finance teams

Why I chose Centime

Centime offers a deeper AR automation package than most accounting and invoicing platforms. Its features include collection campaigns, recurring invoicing, customer-specific autopay, payment delay predictions, cash flow forecasting, payment collection, and cash reconciliation, with integrations for QuickBooks, NetSuite, and Sage Intacct.

I chose Centime for established small businesses with a controller, finance manager, or AR employee. Its invoice-volume pricing can be attractive for teams that need multiple users because Centime does not charge per AR user, though its mid-market positioning makes it less suitable for freelancers and microbusinesses.

When Centime may not fit: Your business needs self-service signup, sends only a small number of invoices, cannot justify an implementation fee, does not have a dedicated finance employee, or prefers publicly listed subscription pricing.

BICentime uses custom pricing based on the products selected and invoice volume. AR pricing scales according to the number of invoices collected rather than the number of users. Discounts may be available for bundling AP and AR, multi-year agreements, and qualifying nonprofit organizations. 

Centime’s official FAQ lists a standard $2,500 implementation fee, although promotional discounts may sometimes apply.

  • AI collection campaigns
  • Recurring invoices
  • Customer-specific autopay
  • Branded customer portal
  • Payment delay predictions
  • Cash flow forecasting
  • Cash reconciliation
  • AP and AR modules
  • QuickBooks, NetSuite, and Sage Intacct integrations

  • Autopay and promise-to-pay tracking
  • Automatic cash application
  • Detailed DSO, aging, and collections analytics

Cons

  • Requires an existing accounting or ERP system
  • Public paid plan pricing needs confirmation
  • More setup than accounting-native invoice tools
  • May be excessive for businesses with low invoice volume

Why I chose Upflow

Upflow is a strong option for B2B businesses whose main challenge is collecting overdue invoices. It supports automated collection workflows, personalized reminders, a branded customer portal, autopay, promise-to-pay tracking, automatic cash application, and real-time AR analytics.

I chose Upflow for companies that already use accounting or finance software but need a stronger collections process. It connects with QuickBooks, Xero, NetSuite, Salesforce, Stripe, and other systems, and adds customer-specific workflows, dispute tracking, promised payment dates, shared account timelines, and account prioritization without replacing the existing accounting platform.

When Upflow may not fit: Your business needs accounting software, sends only a few invoices each month, wants a clear low-cost monthly subscription, does not need a formal collections process, or primarily sells subscriptions.

Upflow advertises a free Discover option, while paid package details and any implementation requirements should be confirmed directly with the provider before publication. Because exact paid plan figures were not clearly available in the reviewed official documentation, businesses should request a full quote that includes platform fees, users, payment costs, onboarding, and required integrations.

  • Automated and personalized reminder workflows
  • Branded customer portal
  • ACH, card, and direct debit payments
  • Autopay
  • Promise to pay
  • Dispute tracking
  • Smart cash application
  • DSO and CEI reporting
  • Accounting and CRM integrations

  • QuickBooks Online and Xero connections
  • Includes accounts payable functions

Cons

  • Limited advanced collections tools
  • Plan and transaction limits require review
  • No advanced cash forecasting
  • Better for payments than full AR management

Why I chose Melio

Melio offers straightforward invoice creation, payment links, reminders, payment tracking, and accounting synchronization. It also supports accounts payable, making it a useful option for owners who want one system for collecting customer payments and paying vendors.

I recommend Melio for small businesses that need a simple invoice payment solution without advanced credit or collections tools. Its core workflow covers creating an invoice, sharing a payment link, tracking payment status, and scheduling vendor payments, though its AR features are lighter than those of BILL, Centime, or Upflow.

When Melio may not fit: Your business needs collection prioritization, cash application, DSO reporting, customer risk scoring, subscription dunning, or detailed cash flow forecasting.

Melio offers four subscription plans:

  • Go: $0 (one user)
  • Core: $25/month, plus $10/month for each additional user
  • Boost: $55/month, plus $10/month for each additional user
  • Unlimited: Custom pricing

Annual billing lowers the subscription cost to $20/month for Core and $44/month for Boost, with additional users costing $8/month.

Transaction fees apply separately. For example, each plan includes a monthly allotment of free ACH payments, after which Melio charges $0.50 per ACH payment. Credit card transactions are generally subject to a 2.9% processing fee, along with fees for certain expedited or international payment methods.

  • Invoice creation
  • Email and payment link delivery
  • Automatic payment reminders
  • Manual reminder emails
  • Customer payment options
  • Invoice status tracking
  • QuickBooks Online and Xero synchronization
  • Accounts payable tools

Pros

  • Customer portal and hosted payment pages
  • More than 35 payment gateway integrations

Cons

  • Receivables is not a standalone product
  • Pricing can be high for a small company
  • Product structure is less suitable for simple invoices
  • Receivables-specific pricing is not publicly isolated

Why I chose Chargebee Receivables

Chargebee Receivables is the most specialized option in this guide. It is built for recurring, usage-based, and hybrid billing rather than standard one-time invoicing, and it works from the same billing record used for quotes, invoices, collections, subscriptions, and revenue recognition.

I recommend it for SaaS and subscription businesses that need dunning, usage billing, seat-based pricing, credits, hybrid pricing, and customer self-service. It is less suitable for freelancers, retailers, and professional services firms that only need simple invoicing and payment collection.

When Chargebee Receivables may not fit: Your business does not sell subscriptions, sends basic one-time invoices, needs free general accounting software, wants standalone AR automation, or cannot justify the cost for its billing volume.

MeChargebee Billing currently lists:

  • Starter: $0 for the first $250,000 in cumulative billing, followed by a 0.75% fee on billing above that threshold
  • Performance: $7,188 annually for up to $100,000 in monthly billing
  • Enterprise: Custom pricing

The Performance package includes smart dunning, advanced and consolidated invoices, migration support, and engineering consultation. Receivables may require separate or bundled pricing, so businesses should request a quote covering every required Chargebee product.

  • Subscription invoicing
  • Usage-based and hybrid billing
  • Smart dunning
  • Failed payment recovery
  • Hosted payment pages
  • Customer self-service portal
  • Multiple payment gateways
  • Invoice-to-cash connection
  • Revenue recognition options

How to choose the best accounts receivable software for your business

  1. Start with the biggest bottleneck. Choose software based on the task taking the most time, such as sending invoices, chasing late payments, reconciling transactions, or managing subscriptions. Small businesses should avoid paying for advanced tools they will not use.
  2. Compare payments and invoicing automation. Review payment methods, recurring invoices, reminders, autopay, saved payment details, processing fees, and deposit times. Prioritize the features that make it easier for customers to pay.
  3. Check accounting and payables connections. Look for reliable two-way sync for customers, invoices, payments, taxes, and bank records. A weak integration can create duplicate work. BILL, Centime, and Melio may also suit businesses that want AP and AR in one system.
  4. Assess the full cost and room to grow. Include subscription fees, user charges, processing fees, setup costs, add-ons, and contract terms. Also check what happens when invoice volume, staff, or billing needs increase so you do not outgrow the software too quickly.

Frequently asked questions

QuickBooks Payments is our top choice for small businesses using QuickBooks because it connects invoicing, payment processing, payment tracking, reminders, and accounting records. Zoho Books is a better low-cost choice, while BILL is stronger for a growing finance team managing both AP and AR.

Yes. QuickBooks can schedule recurring invoices, accept online payments, send reminders, track invoice activity, and automatically record online payments in QuickBooks Online. It does not provide the same collections depth as a dedicated AR platform such as Upflow or Centime.

Invoicing software creates and sends invoices. AR automation software may also manage payment reminders, collections workflows, payment matching, overdue accounts, customer portals, and cash flow reporting. Many SMB accounting products sit between these categories by combining invoicing with basic payment automation.

Zoho Books offers a free plan for qualifying businesses with annual revenue of no more than $50,000. The plan supports up to 1,000 invoices per year and includes recurring invoices, reminders, online payments, a customer portal, and bank reconciliation.

QuickBooks Payments is best for QuickBooks users, Zoho Books is best for low-cost accounting and invoicing, Melio is best for simple payment links, and BILL is better for growing businesses that need AP and AR workflows.

SaaS billing solutions manage recurring subscriptions, usage charges, plan changes, payment retries, dunning, and customer self-service. Chargebee is the strongest SaaS billing tool in this guide because its Receivables product connects collections to the underlying subscription billing record.

Some products do. BILL, Centime, and Melio offer both accounts payable and accounts receivable functions. QuickBooks also supports bill management, although its Payments product is primarily focused on collecting customer payments.
