How JustPaid.io saved over 6 months of engineering labor with Rutter
Explore how JustPaid.io utilized Rutter's Accounting API to simplify complex accounting integrations, saving over $100,000 and 6 months in engineering labor, enabling rapid merchant onboarding.

Best-in-class AP/AR automation platform requires complex ERP integrations
Building a top-tier AP/AR automation platform required intricate ERP integrations, a challenge that JustPaid.io was ready to tackle head-on. Due to Anelya's decade of experience running an accounting firm servicing over 800 venture-backed startups, she knew the tools available were limited and prone to human error.
Anelya and her team observed the wave of automation transforming other sectors while accounting lagged behind in manual processes. She felt compelled to make a change, and decided to found JustPaid.io
For JustPaid.io to take flight, the team required:
- Deep, complex ERP system integrations
- Rapid deployment of these ERP systems
Conscious that hacking together an in-house solution would be costly and time-consuming, they turned to Rutter.
The JustPaid team explored many solutions, but none met their high expectations – until they found Rutter. Rutter's competitive pricing and deep Accounting API capabilities elevated it as the undoubtedly superior vendor.
JustPaid.io rigorously tested out Rutter’s solution by:
- Setting up API endpoint parameters
- Ensuring Rutter met each of those basic specs
- Evaluating our API documentation for ERP systems
Rutter’s integrations passed each test with flying colors, so JustPaid.io decided to team up. Since then, Anelya highlights three ways Rutter is a game-changer for getting their product off the ground.
Thanks to Rutter's thorough support and their depth of technical knowledge, the JustPaid.io team was able to integrate swiftly and seamlessly. Anelya highlights:
- JustPaid.io works with a dedicated Rutter team of engineers and solution architects, who are both thorough and attentive. Anelya appreciates how they clearly take time to understand precisely what JustPaid.io needs.
- The Rutter team is always just a DM away and quick to respond via Slack.
- From the get-go, Rutter was open to negotiating contracts to match JustPaid.io’s budget.
“I didn’t want to slow down our growth to build the solution when we could just buy it from Rutter. While we could have eventually built the capability in-house, buying makes far more sense for many startups’ unit economics.”
Rutter delivered the swift integration solution JustPaid.io needed from the very beginning. Anelya describes a quick and seamless onboarding experience, where the Rutter team was always one step ahead of the program. Speed is especially critical for JustPaid.io as they search for product-market fit. They are iterating frequently, and Rutter allows them to launch new products to market faster for quick learnings.
Beyond technical speed, the Rutter team prioritizes the client experience at all times. While a one-size-fits-all integration solution is enticing, in reality, achieving successful integration often necessitates customized building to address unique requirements and finalize implementation.
With just a few lines of code, JustPaid.io implemented an AP automation workflow that allows their merchants to seamlessly sync bill payments data to their accounting software. Not only does the Rutter Accounting API support AP automation workflows, but it also caters to other related workflows, including AR. Such versatility enables companies like JustPaid.io to broaden their product offerings and expand their future capabilities.
Rutter enables JustPaid.io’s core product functionality so they can onboard clients as quickly as possible with little-to-no engineering effort. This improves their customer experience in several ways:
- One-click accounting integrations – JustPaid.io's users can easily connect to QuickBooks or Sage with just a single click, so they can view all their financial transactions and insights on JustPaid.io's dashboard.
- Reliable data – Customers can confidently enter their billing and invoice details on JustPaid.io, knowing that the data will accurately sync back to their accounting software.
With Rutter, JustPaid.io has achieved:
- $100,000+ saved in personnel costs
- 6 months saved in engineering labor
- 17+ merchants acquired and onboarded in less than a month
“With just one click authorization, JustPaid.io customers connect their stores and are brought back to JustPaid.io's UI where they can view all their transactions, bills, invoices, and get all the financial insight that Rutter’s data provides. It’s seamless for users to disconnect from an old solution and start using the product.”
