Best Platforms for Accounts Payable Approvals

A few years back, AP processes were about manually entering vendor invoice details, chasing down approvals, and finally cutting checks. However, relying on spreadsheets and paper-based approvals makes it harder to control costs, analyze spending patterns, and maintain healthy vendor relationships. Human errors pile up at every step, resulting in wrong calculations, incorrect payments, and financial chaos that ripples through your entire operation. 

Aberdeen Group found that 20% of invoices contain errors or missing information. Ardent discovered that AP departments waste nearly 25% of their time just handling supplier questions and tracking down lost details. Then comes the approval nightmare. Paper documents and endless email chains kill your payment timeline. 

When that happens, you miss early payment discounts and sometimes get hit with late fees. Both eat into margins and damage the supplier's trust. Then there's the hidden cost. Manually processing an invoice costs around $15 per invoice. The good news is that every one of these pain points has the same fix: automation. 

Automated platforms offer higher speed, accuracy, and efficiency at a fraction of the cost. But which automated AP platform works best for your firm? After years of hands-on experience with automated AP platforms, I've identified 5 platforms that actually deliver real efficiency and financial control in the industries they're tailored for. In our review, I'll also show you which platform works best in which industry, so you can choose an AP solution that is tailored to your firm's needs.

Best Platforms for Accounts Payable Approvals

AP software automates your entire payment process using custom instructions tailored to your business. The platform filters, categorizes, matches, and validates accounting data, then pushes it through your system for recording. The purpose is simple: pay the right vendors, the right amounts, and at the right time. The strongest AP automation platforms combine AI, PDF text extraction and/or OCR scanning for invoice data capture, full invoice processing workflows, automated approval routing, and secure payment options. 

However, not every platform offers the same toolkit. Some include electronic document matching, others don't. A few can automatically pull bills from vendor portals, while others require manual uploads. After extensive testing of different platforms in different industries, here are the platforms that actually deliver results.

LeapAP

LeapAP is built specifically for property and community management, covering condos, HOAs, commercial properties, and residential portfolios. It takes what used to be a paper-heavy, error-prone process and turns it into a streamlined digital workflow. You can receive, code, approve, post, and pay invoices from anywhere. Simply have invoices sent directly to LeapAP or upload your invoices, and the AI parser automatically extracts dates, invoice numbers, and amounts. 

The built-in duplicate protection prevents costly mistakes such as paying the same vendor twice. The system handles utility automation, pulling bills directly from provider portals so your team doesn't have to log in and download them manually. On average, LeapAP cuts your AP costs by up to 80%. 

Then you have full visibility with detailed audit trails that log every action taken on an invoice. Once the invoices are approved, you can make payments directly from the platform using the payment module. The platform supports automated checks, EFT, ACH, and card transactions. LeapAP integrates seamlessly with accounting systems such as QuickBooks Desktop, QuickBooks Online, Xero, Buildium, Rent Manager, Yardi Voyager, and Shiftsuite. So, all data stays synchronized. 

Since the platform is tailored for property management, it's already trusted by major firms like Quarter Park Management, Colyvan Pacific, CPE, Fleske, Laucandrique, and Apollo Property Management, earning an impressive 4.9-star rating on G2.

Key Features 

• Automatic data extraction from invoices
• Automatic utility bill downloads
• One-click digital approvals
• Automated payments and check writing
• Remote approval access
• Intelligent invoice coding
• Duplicate invoice screening

Stampli

Stampli is a cloud-based AP automation platform that covers the full purchasing cycle, from procurement intake to payment, while giving you complete visibility and control at every step. Their AI system, Billy the Bot, adapts to your specific AP processes and business structure. Billy the Bot has been trained on a massive dataset, so it quickly learns invoice formats and accurately captures both header and line-item details. 

It handles multi-page invoices, multi-format files, and even documents containing multiple invoices. Stampli's invoice capture is fully automated, and AP teams get invoices instantly without waiting for a manual verification step. The scale is impressive. Stampli processes over $90 billion in invoices annually for more than 1,600 customers, saving millions of labor hours. It supports native integrations with over 70 ERPs, including Sage, Microsoft, Oracle, SAP, QuickBooks, Acumatica, Dealertrack, and more. These prebuilt connections mean you can deploy in days without coding. 

Once live, Stampli automatically pulls PO data from your ERP and displays it directly on the invoice screen in real time. Customer satisfaction is one of Stampli's strongest selling points. It earned a 99/100 satisfaction score, ranking as a leader in the G2 Grid for Accounts Payable and taking the #1 spot for Implementation and Relationships based on support quality, ease of doing business, and likelihood to recommend. 

That said, we noticed their G2 user rating is 4.6 stars, which is still lower than LeapAP's 4.9. Industry adoption also tells a story. Looking at their customer base of 178 companies, the largest segments are computer software with 10%, hospital and health care with 8%, financial services with 7%, construction with 6%, and IT services with 5%. While it's a strong general AP automation tool, it isn't tailored specifically for industries like property management.    

Key Features

• Purchase order management, including creation, approvals, and ERP exports with preserved configurations
• End-to-end workflow automation covering procurement intake forms, invoice processing, approvals, and payments
• Consolidated payment automation for ACH, checks, wires, and virtual cards in one platform
• Real-time budget management integrated into approval workflows for better spending control
• Centralized vendor management, including interactions, document storage, and compliance tracking

Tipalti

Tipalti is a payment automation platform built to take the entire supplier payment cycle, from onboarding to the final payment, and make it run almost entirely on autopilot. Invoices can be emailed in by suppliers or uploaded directly into a secure portal, where every step of the process is tracked. The platform's AI Smart Scan technology goes well beyond traditional OCR. 

It reads invoices at both the header and line-item levels, adapting to variations in format and extracting data from even the most complex tables. It learns your coding patterns, automatically applying fields like department, location, tax codes, and expense accounts. It even handles tax coding by matching invoice tax amounts to the correct rates and codes, reducing manual work. Their two-way and three-way matching are fully configurable at both header and line levels, with tolerance ranges to handle small discrepancies. 

When mismatches do happen, you can set up exception approvals for faster resolution. The color-coded, intuitive interface makes it easy to see where issues stand. Collaboration is built in. With Tipalti Comments, AP teams and approvers can tag colleagues, attach documents, and send messages directly inside the platform. Approvers can even reply by email without logging in, something that speeds up approvals. 

On average, Tipalti helps eliminate 80% of manual workload and close books 25% faster. In fact, Tipalti has made the Inc. 5000 and Deloitte Fast 500 lists five years in a row, one of only 15 companies to do so. On the supplier side, automated updates and self-service portals reduce the flood of inquiries. Vendors can track invoice status, view remittance details, and access tax documents without having to contact your AP team. 

Once payments go out, Tipalti pushes real-time reconciliation data straight to your ERP. Integration is broad, with support for major systems such as Oracle NetSuite, Sage, Microsoft Dynamics 365, QuickBooks, Acumatica, and Xero. Payments can be made via checks, ACH, international wires in local currency, or virtual cards. Their pricing includes three tiers: Select at $99/month, Advanced at $199/month, and Elevate with custom pricing. 

That said, its 4.4-star G2 rating puts it behind LeapAP. Also, looking at their customer base, Tipalti mainly targets technology companies, marketplaces, and e-commerce platforms, such as GoDaddy, Roku, WordPress.com, Amazon Twitch, ClassPass, GoPro, Twitter, Roblox, and Zola.  

Key Features

• AI-powered Smart Scan for advanced data capture
• Rule-based approval automation

Bill.com

BILL is a cloud-based financial management software designed to handle both your accounts payable and accounts receivable in one place. It's aimed at small to midsize businesses looking for an integrated solution covering bill payments, invoicing, accounts payable, and receivables. The platform can save about 50% of your time on accounts payable compared to traditional methods. 

BILL operates primarily in the cloud, letting you access the system remotely from anywhere with the Internet. They also offer a desktop application for businesses that prefer managing financial tasks locally. BILL integrates with major accounting systems like QuickBooks, Sage Intacct, NetSuite, and Xero, making it easy to fit into an existing tech stack. With BILL, every account has its own BILL inbox, where invoices can be sent via email, fax, upload, or drag-and-drop. Vendors can send invoices directly to this inbox, too. 

From there, Ava, BILL's virtual assistant, scans the document and captures key details like vendor name, invoice date, and payment amount. For purchase orders created in your accounting software, you can sync the PO with BILL to match. Ava automatically captures PO numbers to save time. Built-in duplicate detection flags identical invoice numbers and links to the original file, reducing errors. Approval workflows are customizable. 

You can add multiple approvers, set rules, and count on automatic notifications. Approvers receive automatic notifications on their overview screen, to-do list, email, and mobile device when away from the desk. There's also a mobile app so you can review, approve, and track payments while on the go. Payments are flexible. BILL supports ACH, checks, virtual cards, and international wires, along with multiple currencies. 

You can send single, bulk, or recurring payments. One of the most convenient features is Pay By Card, which lets you pay vendors with a credit card even if they don't normally take them. Everything syncs back to your accounting system with a click, speeding up reconciliations and month-end closes. 

BILL offers four plans: Essentials at $39 per person per month, Team at $49 per person per month, Corporate at $69 per person per month, and Enterprise with custom pricing. Pricing increases as you add features like accounting integration and payment automation. The platform gets solid feedback of 7.7/10 on TrustRadius and 4.3/5 on G2. However, the platform has a rather low rating of 2.8/5 on TrustPilot.

Final Thoughts

Every accounts payable platform has its own strengths. Some shine when it comes to speeding up B2B vendor payments. Others are stronger at keeping company expenses under control. What matters most is finding the AP solution that fits your business. Some platforms work best for computer software, e-commerce, and IT companies. Others serve health and financial services well. And some are built specifically for real estate and property management. 

Choose an automated AP software tailored for your industry. That's how you ensure it has every feature that meets your workflows, your compliance needs, and your payment processes. Take LeapAP as an example. It was built for property management from the ground up. Every feature, from invoice capture to automated approvals, fits the way the PM industry operates.
