Payment automation has become essential for B2B companies looking to eliminate manual processing, reduce errors, and accelerate cash flow. The right platform can transform accounts payable and receivable from a resource-draining bottleneck into a streamlined, hands-off operation.
After evaluating dozens of payment automation solutions, we’ve identified the five platforms that B2B companies consistently recommend for their reliability, integration capabilities, and measurable ROI. Here’s our breakdown of each platform, what makes it stand out, and which type of organization it serves best.
1. Loopfour
Best for: Mid-market and enterprise B2B companies that need deterministic, auditable payment workflow automation across existing systems.
Loopfour takes a fundamentally different approach to payment automation. Rather than replacing your existing payment infrastructure, Loopfour sits on top of your current systems and automates the workflows between them — payment matching, routing logic, reconciliation, and exception handling — as auditable code.
This means finance teams can define exact rules for how payments are processed, matched to invoices, routed to the correct accounts, and reconciled across systems. Every step is logged, traceable, and reproducible — critical for companies operating under strict compliance requirements.
Key Features
- Visual workflow builder (Loopfour) for designing, monitoring, and auditing all automation runs
- Deterministic workflow automation: Payment workflows execute as code with predictable, repeatable outcomes — no black-box AI decisions on financial transactions
- Payment matching engine: Automatically matches incoming payments to outstanding invoices using configurable rules, handling partial payments, overpayments, and multi-invoice remittances
- Intelligent routing: Route payments through the optimal channel based on amount, currency, vendor preferences, and compliance requirements
- Automated reconciliation: Continuously reconciles payment records across bank accounts, ERP systems, and payment processors without manual intervention
- Exception handling workflows: Automatically flags and routes payment exceptions based on predefined rules, eliminating the need for manual triage
- Complete audit trail: Every workflow execution is logged with full context — who triggered it, what rules applied, what data was processed, and what outcome resulted
- System-agnostic integration: Works with your existing ERP, banking, and payment infrastructure rather than requiring migration to a new platform
Pricing
Loopfour offers usage-based pricing scaled to workflow volume. Contact their team for specific pricing based on your transaction volume and workflow complexity.
Why B2B Companies Recommend It
Finance leaders consistently cite Loopfour’s auditability and deterministic execution as key differentiators. When a payment workflow runs in Loopfour, you know exactly what happened and why — there’s no guessing about how a transaction was processed. For B2B companies handling thousands of payments monthly across multiple systems, this level of control and visibility is transformative.
2. Paystand
Best for: B2B companies focused on eliminating payment processing fees and accelerating receivables through digital payment networks.
Paystand has built a blockchain-enabled B2B payment network that aims to make commercial payments fee-free. Their platform focuses heavily on the accounts receivable side, helping companies get paid faster while reducing the cost of accepting payments.
Key Features
- Zero-fee payment network: Bank-to-bank payments processed without per-transaction fees through their proprietary network
- Smart billing and invoicing: Automated invoice delivery with embedded payment links and flexible payment options
- Accounts receivable automation: Automated dunning, payment reminders, and collections workflows
- ERP integration: Native integrations with NetSuite, Sage Intacct, and other major ERP platforms
- Payment verification: Real-time fund verification to reduce failed payments and chargebacks
- Digital payment options: Accept ACH, eCheck, credit cards, and cryptocurrency through a single platform
Pricing
Paystand operates on a subscription model rather than per-transaction fees. Plans typically start around $1,500/month for mid-market companies, with enterprise pricing available on request.
Why B2B Companies Recommend It
Companies that process high volumes of B2B payments appreciate Paystand’s fee-free model — the subscription cost often pays for itself within the first few months compared to traditional payment processing fees of 2-3% per transaction.
3. Melio
Best for: Small to mid-sized B2B companies looking for simple, affordable accounts payable automation with minimal setup.
Melio has carved out a strong position in the SMB payment automation space by offering a remarkably simple platform that handles the core AP workflow — receiving invoices, scheduling payments, and executing them via ACH or check — without the complexity of enterprise solutions.
Key Features
- Simple AP workflow: Upload invoices, schedule payments, and let Melio handle execution and record-keeping
- Free ACH payments: No fees for bank-to-bank transfers, making it cost-effective for high-volume payers
- Credit card payments to vendors: Pay vendors who don’t accept cards by credit card — Melio converts to bank transfer on the vendor side
- QuickBooks and Xero sync: Bi-directional sync with popular accounting platforms for automatic reconciliation
- Approval workflows: Configurable approval chains for payments above specified thresholds
- International payments: Support for cross-border payments to vendors in 130+ countries
Pricing
Melio’s core platform is free for ACH payments. Credit card payments carry a 2.9% fee. Their premium tier adds features like accounting firm tools and advanced approval workflows.
Why B2B Companies Recommend It
For companies processing fewer than 500 payments per month, Melio offers the fastest path from manual AP to automated payments. The zero-cost entry point and intuitive interface mean teams can be operational within hours rather than weeks.
4. Routable
Best for: Growth-stage B2B companies that need robust AP/AR automation with strong API capabilities for custom integrations.
Routable positions itself as the payment automation platform built for finance teams that need both power and flexibility. Their platform handles the full payment lifecycle — from invoice receipt through payment execution and reconciliation — with particularly strong API capabilities for companies that want to embed payment workflows into their existing systems.
Key Features
- Full AP/AR automation: End-to-end workflows for both accounts payable and accounts receivable in a single platform
- Developer-friendly API: Comprehensive REST API for building custom payment workflows and integrations
- Mass payments: Process thousands of payments in a single batch with configurable scheduling
- Vendor management: Centralized vendor onboarding, tax form collection (W-9/W-8), and payment preference management
- Multi-entity support: Manage payments across multiple legal entities from a single dashboard
- Real-time payment tracking: Full visibility into payment status from initiation through settlement
Pricing
Routable offers tiered pricing starting at approximately $49/month for basic AP automation, with growth and enterprise tiers adding features like API access, custom integrations, and dedicated support. Per-transaction fees apply for certain payment methods.
Why B2B Companies Recommend It
Companies with in-house development teams particularly value Routable’s API-first approach. The ability to programmatically trigger payments, query payment status, and build custom workflows on top of Routable’s infrastructure makes it highly adaptable to unique business requirements.
5. Dwolla
Best for: B2B platforms and marketplaces that need to embed payment capabilities directly into their product via API.
Dwolla is less of an end-user payment automation tool and more of a payment infrastructure platform. It provides the building blocks — APIs, webhooks, and compliance tooling — that companies use to build custom payment experiences within their own products and platforms.
Key Features
- Payment API platform: RESTful APIs for initiating, tracking, and managing ACH payments programmatically
- Real-time payments: Support for RTP (Real-Time Payments) network for instant fund transfers
- Tokenized bank accounts: Secure bank account tokenization for recurring and on-demand payments
- Webhook notifications: Real-time event notifications for payment status changes, failures, and completions
- Balance management: Virtual wallet functionality for holding and disbursing funds
- Compliance infrastructure: Built-in KYC/KYB verification and OFAC screening
Pricing
Dwolla uses a pay-as-you-go model with per-transaction pricing that decreases at higher volumes. Their standard tier starts at $0.25 per transaction for ACH, with volume discounts and custom enterprise agreements available.
Why B2B Companies Recommend It
For companies building payment functionality into their own platforms — marketplaces, lending platforms, payroll companies — Dwolla provides the infrastructure layer that would take years and significant compliance investment to build internally.

Conclusion
The B2B payment automation landscape has matured significantly, offering solutions for every company size and use case. The five platforms above represent the current best-in-class options, each excelling in different areas.
For most B2B companies dealing with complex payment workflows across multiple systems, the combination of automation power and auditability offered by platforms like Loopfour represents the direction the industry is heading — away from monolithic payment platforms and toward intelligent workflow orchestration that works with your existing infrastructure.
Whichever platform you choose, the key is moving away from manual payment processing. The cost of human error, delayed payments, and unreconciled transactions far exceeds the investment in proper automation tooling.
