Insourcing vs. Outsourcing ERP: Is There a Better Way?
We often get asked for our opinion on insourcing vs. outsourcing. Do we see firms get better results with keeping everything in-house to protect data and processes or outsourcing to bring costs down? Increasingly we are seeing the answer may be a little of both.
Insourcing gives you full control of your systems and information, but it comes with the cost of salaries, benefits, training, and the ongoing work of recruiting and retaining talent. Outsourcing can reduce the employee cost burden and provide flexibility, but you lose control of your systems and data and may run into gaps in visibility.
For teams that care about governance and still need room to adapt, neither option feels like a perfect fit.
A More Practical Middle Ground
A growing number of organizations are choosing a different model: keep ownership of the systems in-house and cosource the day-to-day work. You still control the ERP, the configurations, the data, and the policies. External specialists handle the operational workload under your oversight.
Most companies only need one or two internal team members to guide deliverables and maintain compliance. The outside team provides the capacity and expertise to keep things moving at the right pace.
Why This Model Works Well
- You keep control of your systems, data, permissions, and workflows. No dependence on a vendor’s platform.
- External support can rise or fall as your workload changes, which helps during peak periods.
- Compliance remains strong because your team reviews and signs off on the important items.
- Technology decisions stay inside your organization, so integrations and automation projects follow your roadmap.
- You can change providers or adjust staffing without re-platforming. The systems stay with you.
Additionally, modern ERPs are evolving quickly and are releasing new automation tools, workflow features, and integration capabilities at a steady pace. When you cosource, your organization decides how to use those innovations to improve efficiency and reduce manual work. If you fully outsource, you pay the same fees regardless of whether the provider becomes more efficient. In some cases, the provider may not take advantage of new ERP features at all, which means your service level stays flat while the technology around you improves. Cosourcing keeps those gains in your hands and lets your internal team direct how automation and process improvements are rolled out.
How Cosourcing Compares to Insourcing
Cosourcing maintains the control insourcing offers, although with lower fixed staffing costs. You get access to specialists without adding permanent roles and you can scale up or down as needed.
How Cosourcing Compares to Outsourcing
Unlike outsourcing, you do not give up system ownership or visibility into your data. Internal processes stay connected and you reduce the risk of vendor dependency or future migration challenges.
When This Approach Really Helps
Organizations usually turn to this model when accuracy, control, and capacity all matter at the same time. Month-end close is an example. Outsourcing can help with the workload, although you lose control of the ERP structure during a period where precision is critical. Insourcing preserves control, although internal teams often cannot absorb the spike in work. Cosourcing solves for both. You keep ownership of the system while outside specialists handle the volume under your oversight.
Audit preparation follows a similar pattern. Outsourcing can push tasks forward, although it often limits visibility into the documentation auditors expect. Insourcing keeps the audit trail intact, although it places a heavy burden on internal staff. Cosourcing lets the internal team guide compliance while external resources support the labor.
The model also fits system clean up, workflow redesign, or integration work. Outsourcing usually means adopting the provider’s processes, which may not align with your ERP. Insourcing keeps alignment, although it requires internal bandwidth and technical skill. Cosourcing allows the organization to drive the design while outside experts execute.
Periods of rapid growth or M&A activity reveal the same challenges. Insourcing cannot scale quickly, and outsourcing can lead to a loss of control at a time when system stability matters most. Cosourcing provides surge capacity while maintaining ownership of the systems that anchor the business during transitions.
The Bottom Line
Cosourcing with system ownership gives organizations the benefits of control, security, and scalability without forcing a choice between full insourcing or outsourcing. It offers a practical structure for teams that value governance and still want the ability to adapt.
