Executive Summary
Revenue is recognized when it is earned. Cash arrives when the customer pays. AR software works on the gap between the two.
Accounts receivable is everything between sending an invoice and having the cash in the bank: delivering invoices, extending credit, reminding customers, handling disputes, taking payments and applying them to open invoices. Automation software takes on that work for B2B companies, where invoices are large, terms are long and customers pay in many ways. The AP automation guide covers the other side of the same transaction: paying suppliers.
The approaches differ by company size and where the work is hardest. AR platforms with payment networks serve suppliers with many customers and payment channels. Collaborative AR puts customers in a shared portal. Order-to-cash suites serve large organizations end to end. Mid-market tools focus on collections. Newer products build AR around AI agents and embedded payments.
Why AR Automation Is a Separate Purchase
ERP systems record receivables; they do little to collect them. The work of collecting happens in email, spreadsheets, bank portals and customers' own AP portals, and it scales with the number of customers rather than the size of the company. AR software takes on that work, so a collections team can cover more accounts and finance can forecast cash with more confidence.
Customers increasingly decide how invoices arrive. Billtrust says it delivers invoices through a single interface for more than 260+ AP portals. Billtrust says invoicing, payments, credit, collections and cash application run as one platform.
The customer experience is part of the product. Versapay describes electronic invoice presentment and payment with a self-serve portal where customers pay, manage accounts or resolve disputes.
ERP Module, AR Platform, or Order-to-Cash Suite
ERP systems record receivables, and some send basic reminders. A dedicated AR platform earns its place when volume, payment channels or collections work outgrow them. An order-to-cash suite goes further, joining orders, credit, invoicing and collections for large organizations.
Suites cover the whole cycle. Esker says it connects every stage of the order-to-cash process in one AI-driven platform to help large organizations accelerate cashflow. Integration with the ERP decides how fast any of these can start. Versapay says it integrates with NetSuite, Intacct, Dynamics 365 or any other ERP via open APIs or flat files.
| Model | What you get | What you take on |
|---|---|---|
| ERP receivables module | Invoices and basic reminders in the ERP | Manual collections and cash matching |
| AR platform with payments | Invoicing, payments, collections and cash application | Integration with ERP and banks |
| Order-to-cash suite | Orders, credit, invoicing and collections together | A larger implementation |
| Collections tool | Reminders, workflows and forecasting | Payments and cash application elsewhere |
| Cash application tool | Matching payments to invoices | Collections handled elsewhere |
How do you evaluate Accounts Receivable & Collections Automation?
Evaluate these products on your customers, payment methods and ERP. The capabilities that decide results are invoice delivery, collections workflows, dispute handling, payments, cash application, credit management, forecasting and reporting.
Cash application is a matching problem suited to automation. Serrala says its Agentic AI matches payments at automation rates of up to 99%. Serrala describes automating collections with Agentic AI-driven prioritization and managing disputes. Collections are becoming account-specific. Invoiced says every account gets its own playbook, with reminders that adjust to how that customer actually pays.
| Capability | What it does | Buyer translation |
|---|---|---|
| Invoice delivery | Email, portal and AP portal delivery | Ask which AP portals are supported. |
| Collections workflows | Reminders, tasks and prioritization | Ask how accounts are prioritized. |
| Dispute management | Tracks and resolves disputes | Ask how disputes reach sales and service. |
| Customer portal | Self-service payment and account view | Test it as your customer would. |
| Payments | ACH, card and other methods | Ask about fees and who pays them. |
| Cash application | Matches payments to invoices | Test with your messiest remittances. |
| Credit management | Sets and monitors credit limits | Matters for new and risky customers. |
| Forecasting and reporting | Cash forecasts and DSO | Ask how forecasts are calculated. |
Vendors in Accounts Receivable & Collections Automation
Representative vendors include Billtrust, Esker, Invoiced, Serrala, Upflow and Versapay. The list is alphabetical, is not a ranking, and is not for sale. How we choose vendors
The approaches below differ by company size and the part of AR they handle best. Several vendors cover more than one, so each approach describes where a product is strongest.
AI agents are the newest pitch in this market. Upflow describes a platform for B2B finance teams to collect smarter and get paid faster, with AI agents that work alongside the team. Tesorio describes AI agents that handle the full order-to-cash lifecycle. Ask each vendor which tasks its agents do without a person, which need approval, and how every action is logged.
| Vendor | Approach | Where it fits |
|---|---|---|
| Billtrust | AR platforms with payment networks | Invoicing, payments and collections on one platform |
| Invoiced | AR with embedded payments | Invoice-to-cash with built-in global payments |
| Versapay | Collaborative AR | Customer portal for payments and disputes |
| Serrala | Finance automation suites | Cash application and collections with AI |
| Upflow | Mid-market collections | Collections with AI agents and revenue-based pricing |
| Esker | Order-to-cash suites | Order-to-cash in one platform for large organizations |
We set out the approaches first and selected one vendor for each afterwards; the table cannot be bought. Close to twenty vendors sell AR and collections automation. Vendors, named here or not, can present their own case in the Spotlight below.
How much should you budget for Accounts Receivable & Collections Automation?
AR software is priced by invoice or revenue volume, users, modules and payment fees. Upflow says its plans are priced by invoiced revenue, with no seat fees. Ask each vendor for the pricing unit, the payment fees and who pays them, and what implementation costs.
The value of AR automation shows up in lower days sales outstanding, fewer write-offs, less manual matching and more accounts per collector. Model it on your own receivables and cash application effort.
| Meter | You are charged for | Grows with | Where it goes wrong |
|---|---|---|---|
| Invoice or revenue volume | Invoices sent or revenue invoiced | Sales growth | Costs rising faster than collections work |
| Users | Collectors and finance staff | Team size | Paying for occasional users |
| Modules | Collections, cash application, credit, portal | Scope | Cash application sold separately |
| Payment fees | Card and ACH transactions | Payment volume | Fees passed to customers or absorbed |
| Implementation | ERP and bank integration | Complexity | Integration left out of the quote |
