Upflow alternatives: 6 AR automation platforms compared for 2026

If your finance team runs Upflow, or has it on a shortlist, and the quote-based pricing, the integration list or the way it is packaged no longer fits, this guide compares six accounts receivable platforms that growing and mid-sized businesses could realistically consider instead: Kolleno, Paidnice, Chaser, Growfin, Versapay and Invoiced by Flywire. Each one automates collections and connects to the accounting systems that Upflow customers typically run, such as Xero, QuickBooks, NetSuite or Sage Intacct. Listed by the size of business each platform is built for, smallest first.

Before you switch: what Upflow offers

Upflow sells accounts receivable software covering AR analytics, collections, cash application and payments. It launched in France selling to small businesses, then moved its focus to the US mid-market, and says it has more than 50 people across the US, Europe and India. Three points are worth checking before you replace it:

• Pricing model. Paid plans (Starter, Grow, Scale, Accelerate and Enterprise) are tiered by annual invoiced revenue and quoted on request, with a yearly commitment. Every plan includes unlimited user seats, and a free Discover plan gives you AR analytics on your live data.
• Integrations. Upflow lists NetSuite, Sage Intacct, QuickBooks Online, Xero, Microsoft Dynamics 365 Business Central, Pennylane and Rillet, plus the billing systems Stripe Billing, Chargebee and Zuora. SAP S/4HANA is listed as coming soon.
• Payments and channels. Upflow Payments, its own payment gateway, carries per-transaction fees and a platform fee. SMS, call and letter reminders are subject to usage fees, while email reminders are unlimited.

Who this comparison is for, and how the platforms were chosen

This guide is for finance leaders and AR managers at growing and mid-sized B2B businesses, in the UK, US and elsewhere, who use or are evaluating Upflow. According to Chaser's 2026 accounts receivable report, businesses using AR automation software are 52% more likely to be paid within two weeks of their invoice due date than those that are not.

A platform is included only if all three of these are true:

• Its own website says it serves small, growing or mid-market businesses, the range Upflow sells to.
• It automates collections and covers at least one of payments, cash application or forecasting.
• It connects natively to at least one of Xero, QuickBooks, NetSuite or Sage Intacct.

Each platform is described on the same criteria: who it is built for, key features, integrations, pricing model, pros and cons. This guide is published by Chaser, which appears in the list.

Upflow alternatives compared

Kolleno

Kolleno describes itself as an AI order-to-cash platform made for CFOs and credit controllers, and says more than 1,000 collection teams of all sizes use it, with offices in London and New York. It covers collections, online payments, cash application, disputes, credit risk and cash flow forecasting.

AI agents run collections and reconciliation within the credit policy you set, and you choose how much autonomy each one has: insights only, a copilot that drafts work, or independent execution.

Key features

• Collections management with AI follow-ups, workflows and a shared collections inbox.
• A customizable payment portal, payment links and multiple payment options.
• Cash application with AI matching and exception handling.
• Dispute management and real-time credit risk monitoring with alerts.
• Cash flow forecasts built from customer payment behavior.
• E-invoicing and surcharge management.
• SMS and call allowances included in every plan, rising by tier.

Pros

• Collections, payments, cash application, disputes and credit risk sit in one platform.
• Publishes prices for its lower plans, and the entry plan offers a free trial.
• Kolleno says onboarding generally takes about 10 days.

Cons

• Priced per user, so cost rises with the size of your team, where Upflow includes unlimited seats.
• Its lower plans connect to Xero, QuickBooks and Sage Intacct. NetSuite, Business Central, SAP and Oracle are listed on its Enterprise plan.
• Kolleno notes that extra charges may apply for integrations, customizations and other add-ons.

Pricing: published on its site, per user, by turnover band.

Paidnice

Paidnice is accounts receivable automation for Xero and QuickBooks, used by service, professional, wholesale and property businesses. It turns your payment terms into automatic actions: reminders, statements, late fees and interest, early payment discounts and payment plans, written back to your ledger.

Plans follow your monthly invoice volume rather than your revenue, run month to month, and your first 20 actions are free with no credit card.

Key features

• Email and SMS reminders from your own domain, plus scheduled calls, in sequences that adapt to each customer's payment behavior.
• Automatic late fees and interest, and prompt payment discounts.
• Payment plans with installment reminders and write-back to Xero and QuickBooks.
• A branded customer payment portal for card, Stripe ACH, BACS and direct debit payments.
• Quote reminders, so prospects hear from you before a quote or estimate expires.
• Scheduled statements, escalation and dispute workflows, and aging and DSO reporting across entities.

Pros

• Month-to-month plans with no contracts or lock-ins.
• Pro plans include unlimited users, with no per-seat fees.
• Paidnice says most teams are live in 15 minutes, with a safe mode to test before anything sends.

Cons

• Standard integrations are Xero, QuickBooks Online and Stripe. NetSuite, Dynamics and Sage come only on its custom plan.
• The Essentials plan allows 2 team members, and sending from your own email domain and payment plans need Pro.
• SMS reminders are charged per message on top of the plan.

Pricing: published on its site, by monthly invoice volume.

Chaser

Chaser is accounts receivable software for mid-market finance teams. It connects to your accounting system or ERP, automates payment reminders by email, SMS, automated phone call and letter, and brings payment tools, credit risk insight and cash flow forecasting into the same platform. When chasing is not enough, a debt collection service and an outsourced credit control service are available inside Chaser too.

Key features

• Automated reminder schedules by email, SMS, automated phone call and letter, set by invoice due date and customer segment.
• Email templates in your own branding and tone, with a record of every reminder sent to each customer.
• A payment portal, payment links in reminders, and payment plans with automated installment chasing.
• Credit monitoring and reports, AI debtor risk insights and late payment prediction.
• Cash flow, revenue and receivables forecasts.
• Integrations with AccountsIQ, iFinance, Microsoft Dynamics 365 Business Central, NetSuite, Odoo, QuickBooks Online, Sage 50 (UK), Sage 200, Sage Business Cloud Accounting, Sage Intacct and Xero, plus Stripe for payments and the Chaser API and CSV import for other systems.
• Debt collection services and Chaser Care, which pairs the software with a dedicated AR specialist.

Pros

• Your AR team sets up and changes reminder schedules and templates itself.
• Reminders, payment collection, credit risk, forecasting and escalation to collections sit in one platform.
• Connects to common mid-market accounting systems in a few clicks, with a 10-day free trial and no setup required.
• Chaser Care is available as an add-on to every plan if you would rather not chase in-house.

Cons

• No deductions management, cash application, accounts payable or treasury modules, which enterprise order-to-cash suites include.
• SAP and Oracle ERP connect through the Chaser API or CSV import, not a native connector.
• The entry plan includes 4 users and 4 automated workflows. Unlimited users and workflows, multi-entity support and the receivables forecast need a higher plan.

What changes if you move from Upflow

Chaser covers the collections side of Upflow: reminders on four channels, a payment portal, credit risk insight and forecasting. It has no cash application module, so if you use Upflow's today, plan how payments will be matched. In return, escalation to collections stays in the same platform.

Using Chaser with Stripe and your ledger

Chaser integrates directly with Stripe, pulling invoice, customer and credit note data, and customers can pay through the Chaser payment portal via Stripe. Chargebee and Zuora are not on Chaser's integrations page, so use the API or CSV import. See all Chaser integrations.

Pricing and getting started

Like Upflow, Chaser sets its plans by revenue rather than per user. Unlike Upflow, it publishes them on the Chaser pricing page. The entry plan includes 4 users and 4 automated workflows; higher plans are unlimited.

Growfin

Growfin describes its platform as AI-powered AR automation tailored for software and SaaS companies, and says it is trusted by high-growth finance teams. It runs collections as a CRM, with cash application, dispute handling and forecasting in the same platform, and offers a Built for NetSuite SuiteApp.

It also brings AR into the tools other teams already use: account managers see collections status inside Slack and Salesforce, so sales and customer success can help resolve disputes.

Key features

• Automated follow-ups at invoice and statement level that pause, resume or stop based on payment behavior.
• An AI customer health score that identifies and prioritizes risky payers.
• AI cash application that matches payments to invoices at line-item level, including partial and bulk payments.
• A self-service portal where customers raise disputes, promise to pay and submit proof of payment.

• Integrations with NetSuite, QuickBooks, Xero, Sage Intacct, Sage X3, Dynamics 365, SAP Business One and Zoho Books, plus Zuora and Chargebee.

Pros

• Collections, disputes and cash application sit in one platform.
• Sales and customer success teams can follow AR from Salesforce and Slack.
• Lists Zuora and Chargebee, which suits subscription billing stacks.
• Offers a 21-day free trial on request.

• NetSuite is where its site goes deepest, so confirm how far other ledger connections go in a demo.

Versapay

Versapay says it is built for both mid-market and enterprise finance teams, and highlights manufacturing, wholesale distribution and professional services. It combines digital invoicing, a self-serve customer portal, collections, cash application and B2B payments on one platform that runs from invoicing to reconciliation.

Its central idea is collaboration: customers pay, manage their accounts and resolve disputes in the same portal your AR team works from, which suits businesses where queries, rather than forgetfulness, hold up payment.

• Collections management that automates tasks and prioritizes high-risk accounts.

Invoiced, acquired by Flywire in 2024, describes itself as an AI-native invoice-to-cash platform built for upper-mid-market and enterprise B2B finance teams. It pairs invoicing, collections, cash application, reporting and forecasting with Flywire's global payments infrastructure.
