ERP Integration Services
Connect your ERP to accounting, CRM, POS, e-commerce, shipping & payment systems.
A custom ERP only pays off when it talks cleanly to the rest of your stack. Our ERP integration services connect your custom ERP software. Or any off-the-shelf ERP like Odoo, NetSuite, or Microsoft Dynamics. To QuickBooks, Xero, Salesforce, HubSpot, Stripe, Shopify, Amazon, FedEx, UPS and DHL. Real-time sync, retry-safe APIs, and a migration plan you can actually execute.
What Are ERP Integration Services?
ERP integration services connect your ERP software with the other tools your business depends on so data flows automatically between them. Instead of copy-pasting invoices from the ERP into QuickBooks, stock levels from Shopify into the ERP, or customer records from Salesforce into the CRM module, everything syncs. In real time or on a schedule. Through APIs, webhooks, and message queues. Done right, integrations eliminate duplicate data entry, remove errors, and give leadership a single source of truth.

Three Integration Approaches. And When to Pick Each
Point-to-Point
Direct API integration between two systems. Simplest, cheapest, fastest. Right choice when you have 1–3 integrations total.
Best for: Small teams, limited integration count
Event-Driven
Asynchronous events through a message queue or event bus. Retry-safe, scalable, decoupled. Right choice when you have 5+ integrations or need real-time sync.
Best for: Growing mid-market companies
Middleware / iPaaS
Platforms like MuleSoft, Zapier, or Make handle the orchestration. Faster to start, but adds a vendor cost. Right choice for non-technical teams with many lightweight integrations.
Best for: Operations-led integrations at scale
Our ERP Integration Delivery Process

Data mapping
1 weekWe document every field, every entity, every transformation. This is the single most skipped step. And the #1 reason integrations fail.
2
API authentication & sandbox setup
3–5 daysOAuth / API key setup, sandbox environment for every connected system, test accounts, rate-limit review.
3
Build & unit test
2–4 weeksBuild the integration with idempotent workers, retry logic, and conflict resolution. Unit tests on every mapping.
4
End-to-end integration test
1 weekRun production-equivalent data through the integration. Validate every edge case. Generate a test report.
5
Cutover & go-live
2–5 daysBackfill historical data, switch to live APIs, monitor closely for the first 72 hours. Hypercare support for 2 weeks.

ERP Integration Services FAQs
What are ERP integration services?
ERP integration services connect your ERP with the other tools your business runs. Accounting, CRM, HRM, POS, shipping, payment gateways, e-commerce and BI. Done well, integrations eliminate duplicate data entry, sync data in real time, and give leadership one source of truth.
What is the difference between ERP integration and ERP customization?
ERP customization changes how the ERP itself behaves. New modules, new fields, new workflows. ERP integration connects the ERP to other systems so data flows between them. Most projects involve both. Timeline Digital offers both as part of the same engagement.
How much do ERP integrations cost?
A simple point-to-point integration (ERP ↔ QuickBooks or ERP ↔ Shopify) costs $3,000–$8,000. A complex many-to-many integration (ERP ↔ Salesforce ↔ Stripe ↔ FedEx) costs $10,000–$30,000. Ongoing maintenance is typically 10–15% of the build cost per year as APIs evolve.
How long do ERP integrations take to build?
Simple REST-API integrations take 1–3 weeks. More complex integrations with data transformation, conflict resolution and real-time sync take 4–8 weeks. Legacy SOAP integrations or connecting to on-premise systems can take 8–16 weeks.
What technologies are used for ERP integration?
We use REST APIs, GraphQL, webhooks, and message queues (AWS SQS, RabbitMQ). For real-time sync we use event-driven architectures. For batch sync we use scheduled jobs with idempotent workers. We prefer native APIs over middleware when possible. Fewer moving parts, lower cost.
Can you integrate with legacy on-premise systems?
Yes. Many mid-market ERPs still connect to legacy databases (Oracle, MSSQL, AS/400) or SOAP APIs. We build secure bridges using VPN tunnels, middleware adapters, or direct database replication depending on the constraints.
Do you handle ERP migration as part of integration services?
Yes. When you move off SAP, Oracle, Odoo or NetSuite to a custom ERP, we handle data migration, historical record preservation, and a cutover plan that minimizes downtime. Most mid-market migrations complete in 2–4 weekends of controlled cutover.
