The complete guide to outsourcing your AP payment lifecycle
Every month, your AP team touches thousands of payments. They print checks, chase exceptions, field supplier calls, and reconcile transactions one by one. Payments as a Service eliminates that entire burden. A single provider takes your approved payment file and handles everything from there: delivery, tracking, supplier communication, fraud screening, and reporting.
Finexio pioneered this category for B2B payments. This guide covers what Payments as a Service is, how it works, who it serves, and what to look for in a provider.
Payments as a Service (PaaS) is a fully managed model where one provider handles the entire payment delivery lifecycle on behalf of a company. The company retains approval authority. The provider does everything after that: routing payments across the right payment rails, managing suppliers, handling exceptions, screening for fraud, and delivering complete reporting.
In the accounts payable context, this model is often called AP Payments as a Service (APaaS). It goes well beyond software-only AP automation, which digitizes the invoice but still leaves payment execution to your team.
Think of it this way: AP automation software gives your team better tools. Payments as a Service gives your team their time back.
Finexio built the first purpose-built APaaS platform for B2B payments. One file in, every approved payment delivered. The AP team approves. Finexio executes.
Manual B2B payment operations are expensive, slow, and risky. Here is what a typical mid-market AP team deals with every month:
The average cost to process a single B2B payment manually is $8.93, according to industry benchmarks. For a company processing 5,000 payments per month, that adds up to over $535,000 per year in processing costs alone. Most of that cost is labor: printing, mailing, reconciling, and responding to supplier inquiries.
AP teams spend 30-40% of their time on payment-related tasks that have nothing to do with strategic finance work. Exception handling, supplier follow-up, payment reconciliation, and check runs consume hours every week.
Check fraud alone costs U.S. businesses billions every year. Paper checks remain the most vulnerable payment method. Without automated fraud prevention controls like bank account validation, KYC screening, and OFAC sanctions checks, every outgoing payment carries risk.
When payments are processed manually or through disconnected systems, finance leaders lack real-time visibility into payment status. This gap creates audit exposure and erodes supplier trust.
Payments as a Service solves all four problems simultaneously. One provider, one integration, one team accountable for the entire payment lifecycle.
The operating model is straightforward. Your company keeps full control over approvals. The PaaS provider handles everything after the approval.
Your approval workflow stays exactly the same. Whether you use an ERP, an AP automation platform, or a custom system, nothing changes on your side.
Once approved, a single payment file is transmitted to the PaaS provider. The integration is typically a flat file, API connection, or direct ERP integration. Finexio supports all three through its platform connections.
The provider routes each payment to the optimal payment rail. Suppliers enrolled in virtual card programs receive vCard payments. Others receive ACH transfers or printed checks.
Every payment passes through fraud prevention controls before release. Finexio's Finexio Shield program backs this with a $1M fraud guarantee on qualifying payments.
The provider delivers every payment and tracks it through settlement. If a payment encounters an issue, the provider owns the exception resolution.
Supplier enablement is ongoing. The provider manages supplier onboarding, payment method enrollment, and all payment-related inquiries.
Complete payment reporting flows back to your systems. Every payment has a full audit trail. Remittance information is delivered to suppliers automatically.
A complete PaaS platform includes five operational pillars. If a provider is missing any of these, they are offering software, not a service.
The provider delivers payments to 100% of your suppliers across all payment rails: virtual card, ACH, check, and accelerated options like Finexio Express. Learn more about payment operations.
Supplier enablement determines how much value you extract from a PaaS program. Finexio uses AI-powered predictive models to drive virtual card adoption rates well above industry averages. Learn more about supplier management.
Every payment is screened before release. Finexio's Finexio Shield program provides a $1M guarantee against B2B payment fraud. Learn more about fraud prevention.
When suppliers accept virtual card payments, the buyer earns revenue share from interchange fees. For many Finexio clients, this revenue share offsets or exceeds the cost of the program. Learn more about payment monetization.
Centralized payment reporting gives finance teams a single view of every payment. Learn more about payment reporting.
This is the most common point of confusion. AP automation software and Payments as a Service are not the same thing.
| Capability | AP Automation Software | Payments as a Service |
|---|---|---|
| Invoice capture and coding | Yes | No (uses your existing system) |
| Payment execution | Partial | Yes, fully managed |
| Multi-rail delivery | Limited | Yes, all rails |
| Supplier enablement | Minimal | Yes, ongoing campaigns |
| Exception handling | Your team resolves | Provider resolves |
| Fraud screening per payment | Rare | Every payment screened |
| Revenue share from virtual card | Varies | Built into the model |
| Supplier inquiry handling | Your team handles | Provider handles |
The bottom line: AP automation digitizes the front end of the payables process. Payments as a Service handles the back end. The most effective AP operations use both together.
Finexio integrates with leading AP automation platforms and ERPs. See Finexio's platform connections.
Building an in-house payment operation requires investment in banking relationships, compliance infrastructure (PCI DSS, SOC 2), supplier management tools, and fraud detection systems. A PaaS provider brings all of this on day one, typically with implementation timelines under 60 days.
PaaS gives you a single partner accountable for the entire payment lifecycle. Finexio clients typically see total AP payment costs drop by 50-70% within the first year. See what Finexio delivers for CFOs.
Your team retains approval authority and gains real-time visibility. But they no longer own the execution burden. More time for cash flow management and vendor strategy. See what Finexio delivers for AP leaders.
Instead of building payment infrastructure from scratch, embed Finexio's white-label payment platform into your product. Your customers get straight-through processing and you earn revenue on every payment. See how Finexio works with technology partners.
Eliminating manual payment processing reduces the per-payment cost from $8.93 to a fraction of that amount. Fewer touches, fewer errors, fewer checks.
Every payment passes through automated verification. Finexio's Shield program backs this with a $1M fraud guarantee.
Virtual card payments generate interchange revenue. For companies with significant volume, this revenue share can offset or exceed the cost of the PaaS program.
AP teams reclaim 30-40% of their time. Supplier inquiries, exception resolution, and check runs are handled by the provider.
Real-time payment tracking, complete audit trails, and centralized reporting replace the black box of manual operations.
Suppliers get paid faster and more reliably. They receive remittance information automatically and have a dedicated contact for payment questions.
A PaaS implementation typically takes 30-60 days. One file connection, no changes to your approval process, and supplier enablement begins immediately.
A complete PaaS platform operates on a three-party model:
Finexio orchestrates payments on top of J.P. Morgan Chase infrastructure, backed by $75M+ in investment and partnerships with both Visa and Mastercard. Fintech agility with institutional-grade banking underneath.
Support for virtual card, ACH, check, and accelerated options. Ask about Card by Mail for hard-to-reach suppliers.
When a payment fails, who fixes it? In a true PaaS model, the provider owns exception resolution.
Ask about bank account validation, KYC/AML screening, and fraud guarantees.
Virtual card adoption rate is the biggest driver of program economics. Ask what rates their clients achieve.
Finexio operates on J.P. Morgan Chase infrastructure with direct Visa and Mastercard partnerships. 10+ years in market.
The provider should integrate with your existing systems. See Finexio's integration partners.
Expect SOC 2 Type II and PCI DSS compliance. See Finexio's security posture.
Payment processing handles the transaction itself. Payments as a Service wraps the entire lifecycle around that transaction: supplier enrollment, intelligent routing, fraud screening, exception management, and reporting. Processing is one step. PaaS is the complete operation.
No. You retain full approval authority. Your existing approval workflows stay exactly the same. The PaaS provider only executes payments you have already approved.
Typical timelines run 30-60 days. The integration is simple because PaaS works with your existing systems. Supplier enablement begins immediately after go-live.
Yes. Virtual card payments generate interchange revenue shared with the buyer. For companies with significant AP volume, this revenue share can offset the entire cost of the program.
Keep it. PaaS is complementary to AP automation, not a replacement. Your platform handles invoice capture and approvals. The PaaS provider handles everything after approval.
No. Finexio serves organizations across mid-market and enterprise segments. Companies processing 1,000+ payments per month typically see the strongest ROI.
Every payment passes through bank account validation, KYC/AML screening, OFAC sanctions checks, and real-time transaction monitoring. The Finexio Shield program provides a $1M guarantee on qualifying transactions.
BPO replaces your staff with the provider's staff doing the same manual work. PaaS replaces the manual work itself with an automated, technology-driven platform. Lower cost, better fraud protection, and complete visibility.
Finexio is the leading AP Payments as a Service platform, built on J.P. Morgan Chase infrastructure and backed by $75M+ in investment. One file in. Every payment delivered.
