ERP and Integration Services
AppsXone builds custom ERP systems and the connections an ERP needs: EDI with trading partners, Amazon and Walmart marketplace integration, QuickBooks and commercial ERP extension, and live carrier rate shopping. Everything is built directly inside your system, with no middleware layer sitting between you and the transaction.
+ RULES
The scope, and what has to get right.
- Custom ERP development. Systems built around how your business actually operates, not bent to fit off-the-shelf software.
- EDI and marketplace integration. Trading partner transaction sets and Amazon, Walmart and Shopify order flow, built directly into the ERP.
- Commercial ERP extension. A browser layer and integrations over AccountMate, Sage or QuickBooks when replacing the ERP is not an option.
- Shipping and carrier integration. Live rate-shopping and label generation across FedEx, UPS and USPS, built into the order flow.
Inside the system, not bolted on.
Direct connections, not middleware
AS2, SFTP or API straight to the trading partner or marketplace, so there is no per-document cost and no black box when something breaks.
Built inside your data model
Integration logic lives in your own ERP codebase, not a separate platform you have to keep in sync by hand.
Every transaction logged
Raw inbound and outbound data is stored alongside the parsed result, so a rejection is traceable to its cause, not reconstructed from memory.

- Off Sage, with the operating history intact: Customers, vendors, items and transaction history were migrated from Sage into a browser-based ERP covering order-to-cash and procure-to-pay, with a full general ledger, receivables and payables, so the business changed systems without losing its records.
- Native EDI inside the ERP: Direct trading-partner connections for Amazon Vendor Central, Walmart, HSN, QVC and Costco with 850, 855, 856, 810, 846 and 997 documents, polled on schedules as short as ten minutes. Every job is tracked on a monitoring dashboard, and there is no third-party EDI middleware in the chain.
- Every channel in one order queue: Amazon Vendor Central and Seller Central (SP-API), Walmart, HSN, QVC, Costco, several Shopify storefronts, eBay and direct wholesale accounts land in one system. Vendor Central purchase orders are accepted or rejected back to Amazon from the same screen that shows system, 3PL and allocated stock.
- Multi-warehouse and multi-3PL stock: Real-time inventory across an owned warehouse operated with a logistics partner, a second third-party warehouse and Amazon fulfillment locations, with warehouse transfer orders and an Amazon inbound shipment request action for FBA.
- International purchasing and landed cost: Ocean and air freight purchase orders carry ETD, bill of lading, ETA and vessel details, and the ERP calculates landed cost at receiving from tariff classification, duty, tariff, harbor surcharge and freight per item.

Common questions.
Do you replace our existing ERP, or build alongside it?
Depends on the system. A commercial ERP like AccountMate or Sage is usually extended rather than replaced. A system that has genuinely run out of room gets rebuilt around the same data your team already relies on.
How is this different from using SPS Commerce or a similar middleware provider?
Middleware sits between you and the trading partner and charges per document. We build the mapping directly into your ERP so there is no ongoing per-document cost and no black box when a transaction fails.
Can you integrate Amazon, Walmart and QuickBooks all in the same system?
Yes. That combination is common: marketplace orders flowing in, inventory and accounting staying in sync, and shipping automated on top.
What if we are not sure whether the problem is the ERP or the integration?
Tell us what is breaking and we will look at both. Most of the time the ERP is fine and the gap is in how it talks to everything around it.
Which of these is the actual bottleneck?
Tell us whether it is a trading partner, a marketplace, or the ERP itself, and we will tell you honestly where to start.
