ERP Software for Manufacturing: How to Choose a System
ERP software connects sales, procurement, warehouse, manufacturing, invoicing and reporting in one system. For a manufacturing company, the right choice depends not on the number of features listed in a presentation, but on whether the system follows your actual process — from the order to the finished product and delivery. With a bespoke ERP system, these processes can be built around the way a specific company operates.

What Is ERP Software?
ERP is a business system that brings a company's operational data together in one place. Instead of having sales in one programme, the warehouse in Excel, the production plan on paper and invoices in separate software, ERP connects these activities into one overall process.
When an employee enters an order, the system can check availability, create a request to a supplier, prepare a production task and provide the expected completion date. After production, the finished goods are recorded in the warehouse, while the sale can proceed to invoicing and delivery without entering the data again.
ERP is not simply a warehouse programme with more menus. It should show who is responsible for each step, what has happened with a particular order and what the costs, deadlines and deviations are.
Which ERP Solutions Are Suitable for Different Companies?
A small trading company with one warehouse and a limited number of employees can start with a standard system for sales, inventory, invoicing and reporting. If the processes are clear and do not change often, an off-the-shelf product is usually faster to implement and easier to train employees on.
A distributor with several warehouses has different requirements. It needs inventory tracking by location, procurement, minimum quantities, batches, prices for different customers and reports on turnover by sales representative or region. In this case, a standard ERP may be sufficient if these features are available and work with Bulgarian documents and accounting processes.
A manufacturing company has a more complex relationship between sales, materials, operations and finished products. It may need recipes, bills of materials, work centres, shifts, waste tracking, batches, serial numbers and quality control. In food manufacturing, for example, shelf life and issuing order are just as important as the stock itself.
For field services, installations or maintenance, ERP must also cover requests, teams, job sheets, vehicle fleets, photos, documents from the field and subsequent invoicing. In such cases, an off-the-shelf warehouse and sales system may not cover the process without significant customisation.
| Company type | What the system should cover | When an off-the-shelf product is sufficient |
|---|---|---|
| Trading | Sales, inventory, purchasing, invoicing, customers and reports | When there are standardised rules and few exceptions |
| Distribution | Multiple warehouses, procurement, price lists, batches and routes | When the required warehouse and logistics modules are ready |
| Manufacturing | Recipes, production operations, materials, batches, cost calculation and planning | When manufacturing follows a standard model supported by the product |
| Field services | Requests, job sheets, teams, vehicle fleet, warehouse and invoicing | When the ready-made modules allow the workflow to be configured |
What Is the Difference Between Off-the-Shelf ERP and Bespoke ERP?
An off-the-shelf ERP is an already developed product. You choose the available modules, configure the parameters and enter your data. Its main advantage is that you start with a proven structure rather than a blank system. The downside is that the team sometimes has to change its habits to work in the way defined by the product.
A bespoke ERP is built around your roles, documents and workflow. This is suitable when you have specialised manufacturing, your own quoting logic, a non-standard pricing method or several systems that already need to exchange data. The downside is the greater need for analysis, testing and gradual development.
Customisation is the middle option. You start with an off-the-shelf product, then add a specific screen, field, report, approval or integration. This makes sense when the core process matches the product and the differences are limited. If every important operation requires a workaround, an additional spreadsheet or manual copying, it is no longer a minor customisation.
| Option | Strength | Risk |
|---|---|---|
| Off-the-shelf product | Quick start with ready-made core modules | Limitations with non-standard processes |
| Off-the-shelf product with customization | A balance between a ready-made foundation and specialized features | Add-ons can complicate future updates |
| Custom ERP | The system follows your rules exactly | Requires detailed analysis, testing and a clear development plan |
What to check in a manufacturing ERP
Warehouse and materials
Check whether the system supports separate warehouses, units of measure, batches, serial numbers and material reservations. For food and other products with an expiry date, the FEFO approach is important — issue the products with the nearest expiry date first. Some manufacturing operations also require traceability of materials used, waste and returns to the warehouse.
Sales and procurement
A customer order should be linked to stock levels and the production plan. Check whether the system shows what can be delivered immediately, what needs to be produced and what is missing from a supplier. Automatic low-stock alerts, supplier requests and price history are useful features.
Production processes
Look for recipes or product specifications, technological operations, work centers, shift plans and records of the materials actually used. The system should allow you to compare planned and actual production. Otherwise, you will see the finished quantity but not know where the time, materials and costs went.
A good example of this type of logic is the Testen Dom — ERP for manufacturing project. The process includes requests from B2B customers, production batches and recipes, a FEFO warehouse with expiry-date tracking, barcodes, invoices and reports.
Reports and cost accounting
A manager needs to see more than turnover — they also need to know which products, customers and orders are delivering results. Check whether you can generate reports on product cost, waste, delayed deliveries, materials used and production-line utilization.
Roles and permissions
The production worker, warehouse employee, salesperson, accountant and manager should not see or change the same data. Roles should restrict access to modules and actions, while the system should keep a history of who made a change, approved a document or adjusted a quantity.
Integrations
ERP systems rarely work in isolation. Check the connections to accounting software, an online store, a courier, a bank, POS, telephony or production equipment. It is important to clarify how data will be exchanged — via API, file, automatic import or manual approval. API integrations are especially important when an order passes through several systems.
When an off-the-shelf product is enough
A standard ERP is a good choice if your processes are close to those built into the system, there are few exceptions and your team can work according to unified rules. It is also suitable when the main goal is to quickly eliminate duplicate data entry and gain a complete view of the warehouse, sales and invoices.
Before buying, ask for a demo based on your scenario. Don't settle for a generic tour of the menus. Provide a sample order with real materials, deadlines, partial stock availability and a last-minute change. This will show you not only what the system can do, but also how many actions are required and where employees will need workarounds.
When customization or custom development is needed
Customization is justified when the difference is clearly limited — for example, a specific report, an additional approval or a connection to an external system. In this case, the ready-made foundation saves time, while the add-on solves the specific problem.
Custom development makes sense when the company's main competitive advantage lies in its process. This could be manufacturing with a non-standard sequence, field work involving many documents, a complex contract model or the need for a single interface for different teams.
For ERP development, the usual scope benchmark is €3,000–€29,300. Where a project falls within this range depends on the number of modules, production complexity, roles, data migration, integrations, mobile access and level of automation.
What questions to ask before commissioning the project
- 01Which processes should be handled in one system
Describe the journey of an order from the customer to delivery. Include exceptions: missing material, partial fulfillment, a complaint, a returned product and a changed deadline.
- 02Which data will be entered only once
Clarify which fields, documents and quantities should be transferred automatically between sales, the warehouse, production, accounting and procurement.
- 03Which reports are needed for decision-making
Prepare specific reports, not just a requirement for a “good report.” Specify who uses them, for what period and what action should follow from them.
- 04Which roles and approvals are required
Describe what each employee can do and which actions require confirmation. Also clarify how the change history will be displayed.
- 05How will the system be supported after launch
Ask about backups, updates, issue response, training and the process for adding new features. ERP implementation does not end when the first version is delivered.
How to Evaluate an ERP Proposal
Compare proposals by scope, not just by the final price. Check which modules are included, what integrations are described, who prepares the data, how many test scenarios will be run and what happens when a requirement changes.
A good proposal describes a specific outcome: for example, an enquiry from an email should become an order, reserve materials, be added to the production plan and generate a delivery document. If it only lists general terms such as “warehouse”, “CRM” and “reports”, too many details will remain unclear until a later stage.
It is useful to start with a priority version that addresses the most costly delay or the most frequent manual data entry. Once the team is working with it and the data has been checked, the remaining automations can be added with less risk.
Frequently asked questions
- What is ERP software?
- ERP software brings together a company’s core processes — sales, purchasing, warehousing, production, invoicing and reporting. Data is entered into a shared system and used by different teams according to their roles.
- Which ERP is right for a manufacturing company?
- The right solution supports recipes or specifications, production operations, materials, batches, costing, inventory and planning. When choosing one, you need to check the specific process, not just whether the product has a “production” module.
- Is off-the-shelf ERP better than a custom-built system?
- Not always. Off-the-shelf ERP is practical for standard processes, while a custom-built system is more suitable for specialised manufacturing, non-standard roles or numerous integrations.
- How much does an ERP system cost?
- The estimated range for ERP development is €3,000–€29,300. The price varies depending on the modules, integrations, data migration, roles, mobile access and the complexity of the production process.
- What should I ask for in an ERP demonstration?
- Ask for a demonstration using a real scenario: a customer order, an inventory check, a material shortage, a production task, finished goods, delivery and an invoice. This will show you how many manual actions remain and whether the system follows the way you work.
