Briefly, what should you know?
The price of custom software is not a package label; It is the result of the number of processes, user roles, data model, integrations, security and support level.
Who is this guide for?
- Businesses looking to automate their manual processes
- Teams deciding between CRM and custom development
- Software company or managers evaluating offers
- Institutions that secure source code, SLA and data ownership
We prepared this guide based on Codeexia's project experience, official sources and real questions that are repeated in bid negotiations. It states the variable fees and technical conditions with its sources; We do not present project estimates as a final offer.
Why are custom software prices discussed in such a wide range? Because custom software is not a packaged product: the process, number of modules, user role, integration intensity and maintenance agreement are the real determinants of the price. The same request to “make CRM” can turn into a 250,000 TL project in one business, and a 1,500,000 TL platform in another business.
In this article, we transparently discuss the basic items that make up the cost of custom software projects, sample scenarios, and the points you should pay attention to when evaluating offers.
6 main factors that determine the price
- Business process complexity: Number of process steps, approval flows, conditional branches.
- Number of modules: Scope of modules such as customer management, quotation, order, stock, reporting.
- User roles: Manager, sales, operations, customer roles and authority hierarchy.
- Integrations: Accounting, e-commerce, logistics, banking, SMS, e-signature and sector-specific systems.
- Scale: Number of concurrent users, data volume and transaction intensity.
- SLA and security: Uptime guarantee, support response time, data backup, compliance (KVKK etc.).
Typical price ranges by project size
| Project type | Typical range | Notes |
|---|---|---|
| Single-purpose automation (small) | 150,000 – 350,000 TL | Tool that automates a repetitive business process |
| CRM/operations software (medium) | 350,000 – 900,000 TL | 3-5 modules, 2-3 integrations, role management |
| ERP-like extensive software | 900,000 TL – 3 million TL | Multiple departments, complex business processes |
| SaaS platform | 800,000 TL + | Multi-tenant architecture, subscription, payment |
| Critical operations system | 1.5 million TL + | High uptime, redundancy, compatibility |
Example scenario: Midsize CRM
A CRM software with customer database + opportunity management + quote module + reporting for a B2B sales team; When developed with 2-3 integrations (accounting, e-mail, telephone) and 4 different user roles, it will be worth between 450,000 - 750,000 TL in the Turkish market by 2026. This figure does not include annual maintenance and SLA.
Why custom software and not SaaS?
- If your processes are non-standard and adaptation to ready-made software is not possible
- When data ownership and control is a priority
- If subscription costs are expected to exceed the cost of custom software in the long run
- When competitive advantage requires technological originality
If your processes are standard, a SaaS product is more economical. However, if the competitive advantage lies in operational uniqueness, custom software may be a clear choice in the long term. Ready or Special? In our article, we examine the total cost of ownership in detail.
How is the integration cost calculated?
Every integration; It refers to API inspection, authentication, data schema compliance, error management, and maintenance. A simple webhook integration and an accounting integration that requires two-way data synchronization are not the same price.
- One-way information transfer: Low
- Two-way sync: Medium
- Real-time and critical data flow: High
Maintenance and SLA
In custom software projects, the maintenance agreement is not just about bug fixing. Security updates, library updates, performance monitoring, minor development hours, and critical incident response should be covered. Response time, resolution time and working hour coverage should be clear in the SLA.
Practical advice
Taking over the project with a single large bill and leaving it neglected is the most expensive way in the long run. The annual maintenance + improvement budget should be planned around 15-20% of the total project.
Things to consider when evaluating an offer
- Listing modules and user roles one by one
- Writing integrations with name and scope
- Creating a time plan based on phases
- Ownership of source code, data and access should be included in the contract
- SLA scope on time/response time level
