ERP integration services cost $5,000 to $150,000 depending on scope. Here's what they cover, the three integration approaches, and how to plan one.
ERP integration services cost roughly $5,000 to $150,000 depending on how many systems you connect and how deep the data mapping goes. A single connection between your ERP and one other system usually lands between $5,000 and $20,000, while a multi-system program with middleware, error handling and custom field mapping runs $60,000 to $150,000 and up. These are planning ranges, not quotes.
| Scope | Typical range | What you get |
|---|---|---|
| One point-to-point connection | $5,000 to $20,000 | Single API or file sync between the ERP and one system |
| Two to three endpoints with field mapping | $20,000 to $60,000 | Bidirectional sync, data transformation, error alerts |
| Multi-system integration program | $60,000 to $150,000+ | Middleware or API layer, monitoring, retry logic, docs |
Most companies do not replace their ERP to get a new capability. They connect it to something else. These are the jobs we see most often.
Payments and banking. Pushing invoices out of the ERP to a payment gateway, then pulling settlement and reconciliation data back in.
E-commerce and marketplaces. Syncing orders, inventory and customers between the storefront and the ERP so stock counts stay accurate.
CRM. Passing quotes, orders and customer records between sales and operations.
Warehousing and logistics. Sending shipments to a 3PL or WMS and receiving status updates back.
Payroll and HR. Exporting approved timesheets and salary runs into payroll software.
Reporting and BI. Streaming ERP data into a warehouse or a dashboard tool.
Each one is a project, not a checkbox. They differ in data direction, frequency, and what happens when a record fails.
Third-party ERP integrations commonly run $5,000 to $50,000 each depending on complexity, a planning benchmark that shows up across ERP implementation studies. A one-way sync of a single object, like pushing new customers from Shopify into NetSuite, sits at the low end. A bidirectional order-to-cash flow with tax, discounts and partial refunds sits at the high end.
Four things move the number.
Budget for the middleware license too if you go that route. iPaaS platforms list at roughly $600 to $6,000 a month depending on connections and volume. Consulting and implementation work on ERP projects runs about $100 to $300 an hour across most firms.
There are three realistic ways to connect an ERP.
Point-to-point. Write code or use a connector to move data directly between two systems. It is cheap and fast when you have one or two connections and a developer who knows the ERP's API. It gets brittle as you add systems: four systems mean six pairs of connections to maintain.
iPaaS or middleware. A platform like MuleSoft, Boomi, Workato or Celigo sits between systems and manages connectors, transformations, retries and logging. It earns its cost when you have several endpoints and want prebuilt connectors instead of custom code. You pay a license on top of the build work.
Custom API layer. Build a thin internal service that owns the integration logic and exposes one consistent API. This is the right choice when the integration is central to your product or when you will keep adding endpoints and want full control. More upfront cost, lower long-run maintenance.
Most of our work lands in the first and third buckets for clients who want to own their code, with iPaaS reserved for teams that would rather operate a tool than maintain code.
Start with a data map, not a tool decision. List every object that has to move: orders, customers, invoices, stock. For each one, record the direction it moves, how often, and which system is the source of truth for each field. The map exposes the real scope faster than any estimate meeting.
Agree on failure behavior before writing code. For each flow, decide whether to retry automatically, queue for manual review, or alert someone. Integration projects quietly go over budget here, because the happy path is easy and the edge cases are not.
Plan a parallel run. Run the new integration alongside the old process for a few weeks and compare numbers before you switch off the manual path. A reconciliation gap of a few percent is normal at first and is exactly what the parallel run is for.
Document and hand over. Someone has to know which fields map to what and where the retry queue lives after the build team leaves.
We treat an integration as a small software project with its own requirements, tests and handover, not as a plugin install. The team maps the data first, builds the sync with retry and logging, runs it in parallel against production data, and only then cuts over. Our backend work is Java and Spring Boot, with Node and Python where a specific connector works better, and we have delivered financial and ERP systems for clients across Brazil, South Africa, Singapore and the US. See our enterprise software page for what a full build or integration engagement looks like.
If your ERP is aging, read our guide to ERP data migration before adding new connections to a system you may replace. If you are deciding between a custom ERP and an off-the-shelf one, this comparison will help. Building from scratch is a different path; our custom ERP roadmap covers it.
Plan on $5,000 to $150,000 depending on scope. A single point-to-point connection runs $5,000 to $20,000, two to three endpoints with field mapping $20,000 to $60,000, and a multi-system program $60,000 to $150,000 and up.
A single point-to-point connection typically takes two to five weeks. A multi-system integration with custom field mapping and parallel runs usually spans two to four months.
No. Point-to-point code or a custom API layer works for most businesses with one to three connections. An iPaaS like MuleSoft, Boomi or Workato earns its cost when you have many endpoints and want prebuilt connectors and monitoring.
Migration moves historical data into a new system once. Integration keeps two or more systems in sync on an ongoing basis. They are different projects with different budgets and different failure modes.
Usually the ERP for financial and inventory data, with the specialist system owning its own domain. Decide this field by field during the data-mapping step, not by assumption.
Yes, through file exports, database-level sync, or a screen-scraping layer. It costs more and breaks more often than a modern API, which is worth knowing before you scope it.
