ERP (Enterprise Resource Planning) is a system that enables businesses to manage their finance, purchasing, inventory, production, and other core business processes on a common data structure. Thanks to ERP, information generated in different departments works together in a related and centralized structure, rather than being isolated from each other.
Finance, purchasing, and production processes are directly interconnected, especially in manufacturing businesses. Purchasing raw materials, recording the financial impact of the purchase, storing raw materials, consuming them in production, and calculating the cost of the resulting product are all different parts of the same workflow. ERP connects these processes, creating a more controlled, traceable, and measurable business structure.
How are Finance, Purchasing, and Production Processes Interconnected with ERP?
1. Creating a Purchase Requirement Through the System
With ERP, the purchasing process typically begins with the emergence of a need. This need may stem from a production plan, minimum stock level, departmental request, or customer order. The system enables the creation of a purchase request for the required product or raw material.
The request can include information such as product code, quantity, date of need, relevant department, and reason for the request. This structure allows the purchasing process to proceed through a standardized workflow instead of relying on personal emails or scattered Excel files.
2. Managing Purchase Approval Processes
Purchase requests can be submitted for approval according to defined rules. Different approval levels can be defined based on the request amount, product group, department, or budget information. For example, purchases above a certain amount may be directed to management or finance approval.
This structure helps in making more controlled purchasing decisions. The system can keep a record of which request was approved by whom and when it was processed.
3. Tracking Suppliers and Purchase Orders
Supplier information, past purchases, prices, delivery terms, and payment conditions can be managed through the ERP system. Approved requests can be converted into purchase orders and linked to the selected supplier.
The status of a purchase order, its expected delivery date, and order quantity can be tracked through the system. This structure allows purchasing teams to more easily monitor open orders and deliveries at risk of delay.
4. Goods Receipt and Stock Update
When the ordered materials arrive at the warehouse, the goods receipt process can be carried out via ERP or integrated WMS. The quantity received, product code, batch number, supplier, and delivery information can be recorded in the system.
Once the goods receipt is complete, the relevant product or raw material stock is updated. At the same time, the materials received can be compared with the purchase order. Situations such as missing deliveries, excess quantities, or different products can be detected on the system.
5. Linking Purchase Transactions with Financial Records
The purchasing process doesn't end with simply receiving the materials in the warehouse. Supplier invoices, payment schedules, and financial obligations must also be followed up. ERP systems link purchasing transactions with finance and accounting processes.
Order, goods receipt, and invoice information can be compared to strengthen control over the purchasing process. Supplier debts, payment dates, and cost records can be managed centrally.
How can ERP be used to achieve production and financial control?
6. Creating Production Orders
An ERP system can enable the creation of production orders based on sales orders, inventory levels, or production plans. The product to be produced, quantity, planned start date, and production recipe are defined within the system.
When a production order is created, the required raw materials can be calculated. If current stocks are sufficient, a reservation can be made for production. If there is a shortage of materials, a purchase request can be created automatically or through a controlled process.
7. Linking Raw Material Consumption to Production
The raw materials used during production can be associated with the relevant production order. The ERP system can track how much of each raw material was consumed, which product it was used in, and when it was deducted from inventory.
With WMS or EBR integration, material lot and actual consumption information can be transferred to the system in more detail. This structure contributes to more accurate calculation of production costs.
8. Calculating Production Costs
With ERP, production costs can be calculated based on raw materials, labor, machine time, energy, overheads, and other cost items. Planned costs can be compared with actual costs, and deviations can be analyzed.
This information helps finance and production teams work together on the same data. It makes it easier to see the impact on product costs when production volumes increase or raw material prices change.
9. Storing the Produced Products
Once production is complete, the finished products can be added to the inventory on the ERP system. Records can be created detailing the product quantity, production date, batch number, and the associated production order.
When a manufactured product enters the inventory, sales and shipping teams can view the updated stock information. This ensures that the entire process, from production to sales, continues on the same data structure.
10. Analyzing Financial and Operational Reports Together
One of the key advantages of ERP is that operational data and financial results can be evaluated within the same system. Purchase costs, production quantities, raw material consumption, inventory values, and sales revenue can all be analyzed together.
Managers can see which products are produced at a higher cost, which raw materials are causing cost increases, and the impact of purchasing prices on financial results. This structure supports more data-driven decision-making.
How to Manage Finance with ERP?
ERP system enables centralized management of income, expenses, supplier receivables, customer accounts receivable, payment schedules, costs, and financial reports. Since operational transactions are linked to financial records, manual data transfer can be reduced.
How to Manage the Purchasing Process with ERP?
The purchasing process can consist of steps such as request creation, approval, supplier selection, order placement, goods receipt, invoice verification, and payment. An ERP system can manage all these steps within a single workflow and associate each transaction with the relevant product, supplier, and financial record.
How does ERP contribute to production planning?
ERP supports production planning by considering sales orders, current inventory, production recipes, and raw material requirements together. The materials needed for the product to be manufactured can be calculated, and any missing raw materials can be directed to the purchasing process.
Is it possible to track production costs with an ERP system?
Yes. On an ERP system, raw material costs, labor, machine usage, and other production expenses can be linked to a product or production order. This allows for comparison of planned and actual costs. Cost variations can be analyzed jointly by the production and finance teams.
How does an ERP system facilitate data flow between Finance and Procurement?
When a purchase order is created, the expected cost information is generated. After receiving the goods, the quantity received is recorded, and when the supplier invoice is processed into the system, the financial obligation arises. The ERP system links these records, enabling purchasing and financial processes to operate based on the same data.
Which systems can ERP integrate with?
ERP can integrate with enterprise systems such as WMS, EBR, LIMS, and QMS. WMS can share warehouse and inventory movements, EBR production records, LIMS laboratory results, and QMS quality processes with the ERP. This structure creates a more integrated data flow from supply to production and financial reporting.
What are the benefits of using ERP for finance, purchasing, and production?
Using an ERP system reduces data duplication between departments, brings purchasing processes under control, keeps inventory information up-to-date, enables more accurate calculation of production costs, and strengthens financial reporting. It also helps the business evaluate its operational and financial performance together.
How should these processes be planned in an ERP implementation?
During ERP implementation, existing finance, purchasing, and production processes should be analyzed in detail. User roles, approval workflows, inventory structure, production recipes, cost calculation methods, and reporting requirements should be determined in advance. Systems requiring integration, such as WMS, EBR, LIMS, or QMS, should also be included in the project scope.
Conclusion
With ERP, managing finance, purchasing, and production processes together centralizes the data flow of the business, from supply to production and financial reporting. Purchase requests, orders, goods receipts, raw material consumption, production costs, and financial records can be linked to each other.
This structure allows departments to work together on shared information instead of different and outdated data. Especially for manufacturing businesses, ERP is one of the essential digital infrastructures that increases operational control and cost visibility by establishing a strong link between inventory, purchasing, production, and finance processes.
