AP Automation Success: The Story Behind the Numbers

Accounts Payable Automation Case Studies

Seeing is believing. 

We’ve all heard this maxim hundreds of times, but it rings especially true when it comes to accounts payable automation. 

At Stampli, we’ve written a lot of content around the benefits of AP automation, the ROI your organization can expect, and even how to work with the management team on implementation

While we certainly encourage you to read about the general benefits of automating your AP processes, there’s no better proof of the efficacy of automated accounts payable process than seeing what other organizations similar to yours have accomplished by implementing a best-in-class AP automation platform.

Keep reading for 10 case studies involving real Stampli customers to learn how about the problems they’ve solved, discover the benefits of accounts payable automation, and gain insight into their implementations and invoice management workflows. 

Let’s jump into the real-world applications of AP automation within organizations in a range of different industries. 

1. Purple Speeds Invoice Processing

Purple is an innovative company that designs and manufactures a range of comfort products including mattresses, pillows, and cushions using its patented Hyper-Elastic Polymer® material, which is designed to improve comfort.

Challenge and Solution

Purple originally encouraged its vendors to send their invoices to a specialized AP email inbox and had two AP team members slog through the invoices manually on a weekly pay run. This resulted in a huge backlog of unpaid invoices, and more importantly, there was no central system to manage everything-and many invoices were improperly documented. 


Upon implementing the Stampli AP automation platform, Purple was able to: 

  • Reduce invoice backlog by 50% within 3 months
  • Eliminate duplicate invoice payments
  • Make invoice approval times 63% faster
  • Properly document 100% of invoices
  • Return valuable time to overworked AP team

“With Stampli, we have reduced the time to process invoices from 8 days to 3 days. One of the areas in which we’ve saved the most time is in getting invoices into the system. The second area in which we’ve dramatically reduced time is in getting approvals.” 

– Peter Taylor, Corporate Controller

2. CTI Increases AP Productivity by 40%

CTI Clinical Trial and Consulting Services (CTI) is a privately held global contract research organization that delivers a complete spectrum of clinical trial and consulting services throughout the therapeutics development lifecycle, from concept to commercialization. 

Challenge and Solution

CTI had recently implemented a new financial system to capture invoices and make payments electronically. However, despite this upgrade, its invoice approval process was still manual, and the rapid company growth absolutely buried the AP team and invoice approvers in paperwork. 

Luckily, Stampli’s solution was flexible enough to fit into CTI’s existing AP processes – including integrating with Sage Intacct – while also enabling streamlined collaboration between AP team members and approvers throughout the company. 


With Stampli’s AP automation integration, CTI was able to: 

  • Process 500-600 invoices per month with a small AP team
  • Switch to 100% paperless processing
  • Boost accounts payable productivity by 40%

“Our CFO is happy to no longer go through mountains of paperwork to approve payments – now she can quickly view invoices and approve them all within Stampli.” 

– Marty Budke, Director of Finance and Accounting

3. Renova Energy Reduces Invoice Processing Time by 50%

Renova Energy is an employee-owned company that delivers practical, sustainable solar energy production and battery storage to residential and commercial customers.

Challenge and Solution

During a period of growth, Renova upgraded its financial system to NetSuite. Unfortunately, the AP team was still manually processing more than 700 invoices a month and spending 80% of their time on manual data entry and tracking down approvals. 

Implementing Stampli eliminated hundreds of hours of manually coding, verifying, and approving invoices. Thanks to Stampli’s seamless integration with Oracle NetSuite and two-way data sync, Renova’s payments are now processed accurately and automatically, all with a clear audit trail. 


Since adopting Stampli, Renova has seen:

  • 50% time savings in accounts payable
  • Increased on-time payments
  • Enhanced collaboration

“A lot of times, accounting does not know who needs to be involved with an invoice. Stampli makes it easy for anyone to be involved.”

– Andrea Monteiro, Accounting Manager

4. Techstars Reduces AP Processing Time by 75%

Techstars is a worldwide network and accelerator that helps startups and entrepreneurs succeed.

Challenge and Solution

Like many of the startups it serves, Techstars needed to scale, and fast. In this case, they needed a way to be able to handle an increased volume of invoices without adding overhead. 

Stampli’s artificial intelligence helper, Billy the Bot, was able to learn Techstars’ patterns and increase their ability to onboard users and process invoices – without breaking the bank.


With Stampli’s Billy bot, Techstars: 

  • Reduced AP process time by 75%
  • Reduced user onboarding time from 20 minutes to 30 seconds

“It’s incredible how quickly the artificial intelligence assistant (Billy the Bot) learns our patterns! I also love the flexibility of the system, such as being able to add a note even after the bill has been pushed to Sage Intacct

I’m just thrilled at the ease of use. Switching to Stampli was the best decision we made all year!”

REVOLVE is an e-commerce powerhouse and trendy women’s apparel retailer. As a trusted premium lifestyle brand and a go-to online source for discovery and inspiration, REVOLVE delivers an engaging customer experience from a vast yet curated offering totaling over 45,000 styles of apparel, footwear, accessories, and beauty products.

Challenge and Solution

Processing invoices was a tedious task that involved the entire AP team. This resulted in a lengthy, error-prone AP process. Upon implementing Stampli, REVOLVE was able to process the same amount of invoices with only a single AP team member. This gave REVOLVE’s AP team more headway to focus efforts on other areas.


Stampli’s AP automation enabled REVOLVE to: 

  • Reduce invoice processing time by 80%
  • Significantly improve collaboration within its AP department

“The task of processing invoices used to involve the whole department working manually, which took time and resulted in errors. Now, everything is completed in ⅕  of the time and is managed by one person.”

7. Spanish Fork City Transforms Invoice Processing

Spanish Fork is a community in central Utah that strives to offer its inhabitants a high quality of life by creating an optimal environment for working, recreating, and enjoying life.

Challenge and Solution

Spanish Fork City has worked for years to make sure it can accommodate growth, but until recently, a single person was charged with sending 1,200+ invoices per month to the right approvers. Spanish Fork City didn’t have an AP process to accommodate growth, and when the COVID-19 pandemic hit, the city’s finance director started looking for an AP solution to automate the process.


Since finding Stampli, Spanish Fork has seen:

  • A 2X reduction in the invoice lifecycle
  • Automated expense allocation across departments
  • 12X reduction in the time to get authorized invoices into Caselle 

Before Stampli, accounting would put invoices into approvers’ in-boxes at the beginning of the week, but usually didn’t have approval until the end of the following week. Now invoices are easily scanned and sent to Stampli on the day of receipt.

  • Implemented a collaborative invoice processing workflow
  • Improved relationships with its vendors
  • Increased visibility into accounts payable

“The increased visibility has improved our relationships with vendors and between our team members internally. At MEC, we believe that a collaborative environment is a key to success, and Stampli has helped us to achieve this with our invoices as well.”
