Custom Acumatica API Integrations That Eliminate Data Silos
Your business runs on more than one system. Acumatica’s open API connects it to the tools you already use, including ecommerce, CRM, payment processors, 3PLs, EDI platforms, and more. Xcellerated Solutions builds and maintains those connections for manufacturers, distributors, and construction companies across the US.
ERP EXPERIENCE
What Is Acumatica API Integration and Why It Matters
Acumatica has a fully open REST API. That means it can connect to virtually any external system your business runs, without requiring a custom workaround for every connection or manual data exports between platforms.
The problem most Acumatica customers face is not that the API does not exist. It is that building an integration correctly takes a developer who understands both the external system and how Acumatica stores and processes data internally. A connection that works in testing but breaks during an Acumatica upgrade, or that syncs the wrong fields, or that creates duplicate records on both sides, is worse than no integration at all.
Xcellerated Solutions builds Acumatica integrations that are designed to hold up. We map the data correctly before we write a line of code, build within Acumatica’s framework so the connection survives platform updates, and test against your actual transaction volume before go-live.
If you are the person who will own this system after go-live, our overview for IT leaders evaluating Acumatica covers cloud security, upgrade handling, and what the open API means for your team’s maintenance load. Integrations also pair naturally with Acumatica workflow automation, where connected data triggers approvals and downstream actions without manual handoffs.
Signs Your Systems Are Not Connected the Way They Should Be
- Your team exports data from Acumatica into a spreadsheet every morning to send to another platform
- Orders placed on your ecommerce site require manual entry into Acumatica to process
- Your 3PL sends fulfillment updates that someone re-enters into your ERP by hand
- Sales orders in your CRM do not automatically create records in Acumatica when a deal closes
- EDI transactions from large retail customers require manual processing on your end
- Inventory counts in Acumatica never match what your warehouse management system shows
Systems We Connect to Acumatica
Celigo
SPS Commerce
EDI compliance for distributors and retailers. We connect Acumatica to SPS Commerce so purchase orders, invoices, and advance ship notices flow automatically without manual processing on either side.
Avalara
Automated sales tax calculation and compliance. We connect Avalara to Acumatica so tax is calculated correctly on every transaction without your finance team managing tax tables manually.
APS Payments
Payment processing integrated directly into Acumatica so payments post to the correct accounts receivable records without manual reconciliation.
Procore
For construction companies running Procore for project management alongside Acumatica for financials, we build the connection that keeps project costs, commitments, and change events in sync between the two systems.
BigCommerce and Shopify
Ecommerce integrations that push orders from your online store into Acumatica for fulfillment, update inventory in real time, and sync customer records between platforms.
Smartsheet
Project tracking and workflow management connected to Acumatica so your operations and finance teams are working from the same project data without maintaining it in two places.
Other platforms
If your business runs a system not listed here, contact our team. If it has an API, there is almost certainly a path to connect it to Acumatica.
How Our Acumatica API Integration Process Works
Discovery and data mapping
We review both systems, including how Acumatica stores data and how the external platform sends or receives it. Every field is mapped before code is written, just to avoid integration problem.
Integration design
We design the connection inside Acumatica’s framework so it stays aligned with the platform’s update path and reduces breakage risk during twice-yearly updates.
Development and build
We build the integration, create transformation logic for fields that do not map directly, and handle exception records before they affect your data.
Testing against real data
We test against your actual transaction volume and data structure, not a sanitized sample. Edge cases that only show up at volume get caught here rather than after go-live.
Go-live and post-launch support
We deploy and monitor the integration through the first live period. Any issues that surface under real operating conditions are resolved before they become larger problems.
Industries We Build Acumatica Integrations For
Manufacturing
We connect Acumatica Manufacturing Edition to production scheduling tools, MES systems, CAD/PLM platforms, and quality management software. Your production data and your financial data run on the same numbers without a manual sync in between.
Distribution
We connect Acumatica to 3PL platforms, EDI providers, ecommerce platforms, and warehouse management systems. Orders flow in, fulfillment flows out, and inventory stays accurate across all of them without your team managing the data movement manually.
Construction
We connect Acumatica to Procore, Smartsheet, and document management systems. Your project management data and your financial data stay in sync without a manual export at the end of every week
Professional Services
We connect Acumatica to CRM platforms, time tracking tools, and project management software. Your sales pipeline, your project costs, and your billing all run from the same data.
Frequently Asked Questions About Acumatica API Integrations
Acumatica supports REST API, OData, and SOAP web services. The REST API is the primary integration method for modern connections and is fully documented by Acumatica. It supports standard CRUD operations across most Acumatica objects, which means most external systems can connect to it without a custom middleware layer.
Not if it is built correctly. We build integrations inside Acumatica’s customization framework, which means they are designed to survive the platform’s twice-yearly update cycle. Integrations built outside the framework or directly against the database tend to break on updates. Ours do not.
Yes, in most cases. Legacy systems with no modern API can often be connected via file-based integration (CSV, XML, flat file) or through a middleware layer. We assess the source system during discovery and determine the most reliable connection method before we start building.
Yes. We regularly inherit integrations that were built by previous developers or implementation partners and have become unreliable or are breaking on updates. We audit the existing integration, document what it does, identify the failure points, and rebuild where needed.
