Why Cheap ERP Software Can Increase Your Operating CostsSLUG (EN): cheap-erp-costs

One of the most common mistakes when comparing ERP systems is focusing on the easiest number to compare: the license or monthly subscription fee. For example, one ERP may cost Rp2 million per month while another costs Rp5 million. At first glance, the first option appears to save Rp36 million per year. But that comparison does not answer a more important question: how much will the business actually spend to make the ERP work with its real processes?

In ERP projects, the difference often appears after the purchase. A low-cost ERP may include basic purchasing, sales, inventory, and accounting modules. Once the company needs marketplace integration, multi-warehouse stock synchronization, purchasing approvals, barcode support, custom reports, WhatsApp integration, or connections to other systems, additional work begins. Each requirement may involve configuration, customization, development, or third-party integration.

Consider an Indonesian distributor operating three warehouses and selling through physical stores and marketplaces. A low-cost ERP may technically have an inventory module, but its stock workflow may not match the company’s actual operations. Staff may continue recording some transactions in Excel, others in the ERP, and others through marketplace systems. The company has purchased an ERP, but manual work has not disappeared. In some cases, a new reconciliation process has been created.

This is why ERP costs should be viewed as the cost of operating the system, not simply the cost of purchasing software. A low initial price can be perfectly reasonable if the software genuinely fits the business. The problem occurs when a low price forces the company to build too many missing components or maintain manual processes that the ERP was supposed to eliminate.

A practical way to evaluate ERP costs is through Total Cost of Ownership, or TCO. The concept is straightforward: calculate the cost of acquiring, implementing, operating, and maintaining the system over a defined period. The software price is only one part of that calculation.

ERP implementation costs can include business process analysis, module configuration, user access setup, workflow design, report configuration, testing, deployment, and go-live support. For a company with complex operations, this work can be much more significant than simply creating user accounts and installing an application.

Data migration is another area that is frequently underestimated. Product data may look simple until a company has thousands of SKUs, inconsistent product names, different units of measure, duplicate suppliers, opening inventory, outstanding receivables, and historical transactions. Migration then requires mapping, cleansing, validation, and testing. SAP specifically identifies data conversion, data input, testing, consultancy, and user training as costs that should be considered in ERP implementation planning.

Training is also more than a one-time workshop. Warehouse staff need different knowledge from purchasing, finance, sales, or management users. New employees will require onboarding later. If the system is difficult to use, the time employees spend figuring out how to complete routine tasks becomes another operating cost.

Then there are integration costs. Indonesian businesses may rely on marketplaces, payment gateways, WhatsApp, thermal printers, barcode scanners, logistics applications, tax systems, or their own websites. If the ERP does not provide the required connectors, the business may need custom integration or continue with manual data entry.

A common pattern appears when the software price is low but the company’s processes are highly specific. During the initial sales discussion, the vendor may say that additional requirements can be built. Technically, that may be true. The important question is what those customizations will cost to build and maintain.

For example, a standard ERP may include purchase orders, but a company may require three approval levels based on purchase value. Purchases below Rp5 million may only require supervisor approval, purchases between Rp5 million and Rp50 million may require manager approval, and purchases above Rp50 million may require director approval. If the ERP does not have a flexible approval engine, implementing this workflow may require custom development.

The cost does not end when the feature is delivered. When the vendor releases a software update, the customization needs to remain compatible. When the company changes its organizational structure, approval workflows may need to be updated. When management requests a new report, development resources may be needed again.

For this reason, our usual approach at Sahabat Teknologi is not to turn every business requirement into a customization. We first separate requirements into three groups: processes that should use the ERP’s standard functionality, processes that can be handled through configuration, and processes that genuinely require custom development.

A good ERP is not necessarily the one with the most customization. A good ERP is one that can cover important business requirements through standard configuration as much as possible, while reserving customization for areas that provide measurable business value.

SAP similarly recommends avoiding unnecessary modifications and maintaining a clean core because excessive customization can increase long-term complexity and future maintenance risk. This is especially relevant for Indonesian businesses that do not have a large internal IT team.

Cheap ERP software is not automatically a bad choice. For a small business with simple operations, an affordable ERP can be the right decision. The problem occurs when the company chooses software purely because of price while its operational requirements have already become much more complex.

For example, a business with one store, one warehouse, a small user base, a manageable product catalog, and no external integrations may not need a highly sophisticated ERP. A simple system covering purchasing, sales, inventory, cash management, and basic reporting can deliver excellent value.

The situation is different for a business with multiple branches, thousands of SKUs, many suppliers, high transaction volume, marketplace channels, approval workflows, and management reporting requirements. In this situation, ERP costs need to be evaluated more comprehensively. Software that saves Rp3 million per month but forces administrators to perform daily Excel exports, imports, and reconciliation may not actually be the cheaper solution.

A practical approach is to model the cost over three to five years. Suppose ERP A costs Rp3 million per month while ERP B costs Rp6 million. It is tempting to choose A immediately. But add implementation, migration, customization, integration, training, support, hardware, and remaining manual work. The apparent subscription savings may become much smaller or disappear completely.

For example, if ERP A saves Rp3 million per month but requires an additional 20 hours of administrative work every month, the company should assign a realistic value to those hours. If it also requires Rp30 million of custom development and Rp20 million of integration work, the real difference between the two systems changes significantly.

These figures are only an illustration of the calculation method, not market price benchmarks. Actual ERP costs depend on users, modules, process complexity, data volume, integrations, vendor services, and customization requirements.

Before selecting an ERP, our recommendation at Sahabat Teknologi is to document the company’s actual business processes rather than simply listing attractive features from a product demo. Document how goods are purchased, who approves purchases, how goods are received, how inventory moves, how sales are recorded, how returns are processed, how payments are handled, and which reports management actually needs.

Then ask the vendor to demonstrate those processes using realistic scenarios. Do not simply ask whether the ERP has inventory management. Give the vendor a specific case: “We have three warehouses, a product can be purchased by BOX but sold by PCS, and marketplace orders need to reduce stock from a specific warehouse. How does your system handle this?” Questions like this reveal much more than a generic feature checklist.

Check what is included in the quoted price. Does it include implementation? Is data migration included? How much data can be migrated? Is user training included? Is an API available? Are marketplace and WhatsApp integrations included, or do they require separate development? What is the customization fee? Who provides technical support? What is the expected response time when the system has an operational issue?

Finally, calculate TCO. Oracle describes ERP TCO as the combination of purchase price, implementation costs, and operating costs over a defined period. This approach helps companies evaluate ERP as a medium-term investment rather than a one-time software purchase.

A simple comparison can start with five numbers: license or subscription cost, implementation cost, customization and integration cost, annual operating cost, and the estimated cost of manual work that remains after implementation.

Cheap ERP software is a sensible choice when the complete calculation shows that it is genuinely more efficient. On the other hand, an ERP with a higher license price can be more economical if it significantly reduces manual work, transaction errors, duplicate data entry, and long-term development requirements.
