From the first call to a fixed price
Projects are quoted at a fixed price for a written scope, so you know the cost before work starts. There is no open-ended hourly billing.
Quick answer: every project gets its own fixed quote after a free 15-minute call. For typical market prices by project type (MVPs, ERP, AI and mobile apps), see the software development pricing guide.

-
Intro call (free)
15 minutes on what you need, your timeline and whether the project is a fit.
-
Fixed-price proposal
A written scope with itemised deliverables, milestones and acceptance criteria.
-
Milestone payments
30% to start, 40% at the midpoint and 30% on completion. Support after launch is optional and month to month.
What you can count on
Fixed price, agreed up front
The price in the proposal is the price you pay for that scope.
You own the code
Source code, database and hosting can sit in your own accounts, as they did when SPSTARPLAST's ERP was handed over.
Changes in writing
Work outside the agreed scope gets a written change request with its price and timeline before it starts.
Support when you want it
After launch, support runs month to month. There is no long-term contract to sign.
What moves the price
The fixed price follows the written scope, so it moves with what the scope holds. These are the things that change it most.
Each quote is made for one project, so there are no figures here. The proposal after the call gives the price for yours.
Modules and screens
How many workflows the software covers, and how many screens and reports each one needs. One workflow costs far less than an ERP that runs a whole plant.
Integrations
Every system the software reads from or writes to, such as accounting, an ERP, payments or e-mail. At SPSTARPLAST, cards sync in from LOGO ERP and accepted quotes post back to it as sales orders.
Roles and access rules
Who may see and change what. Per-user access to each functional area, as in SPSTARPLAST's ERP, takes more work than one shared login.
Platforms
A web app, an iOS app, an Android app, or more than one. Each platform adds its own build and testing, and apps add store review.
Data migration
Records brought in from spreadsheets or an old system, then cleaned, matched and checked before the new system goes live.
AI components and evaluation data
A feature on a hosted model costs less than a model trained on your documents. Either way, testing on examples the model has never seen is part of the work, as Otocropper was tested on a book it never saw in training.
Languages
Each interface language adds translation and layout checks, and right-to-left Arabic adds more. 1in46 runs in English, Turkish, Arabic and Spanish.
Who signs the contract
Stratagem Systems works with companies in Türkiye and abroad; contracts are signed with Stratagem Systems LLC (Texas), founded in Houston in 2023.
One written agreement per project
It sets out the scope, deliverables and timeline, the payment schedule, code ownership, support and confidentiality.
Texas law
The terms of service are governed by Texas law, and disputes go to the courts of Harris County, Texas.
The code is yours once paid
When the project is paid in full, you own the custom code written for it. Third-party libraries keep their own licenses.
Prices in US dollars
Prices are in US dollars unless the proposal names another currency.
The terms of service set the general rules; the written agreement for your project takes precedence.
Pricing FAQ
Why isn't there a price list?
Because projects differ too much. A small automation script and a 16-module ERP like the one built for SPSTARPLAST have little in common, so the quote comes after a call about your project.
Where can I see typical prices?
The pricing guide lists market rates and typical cost ranges by project type, and fixed bid vs time and materials explains the pricing models.
Do you work with small companies?
Yes. Clients so far range from a manufacturer and a school group to a single healthcare practice, and Savas also builds and publishes his own apps.
How are changes handled during the project?
Small adjustments inside the agreed scope are included. Larger changes get a written change order with the price and timeline impact before any work starts.
What technologies do you use?
Whatever fits the job. Current projects use Next.js and React, TypeScript, Python and FastAPI, PostgreSQL and Supabase, SwiftUI and React Native for apps, PyTorch for vision models, and the Google Ads API.
Can I see examples of your work?
Yes. The case studies cover the SPSTARPLAST ERP, Dr. Ayberk Akcay's Google Ads automation, the AI homework platform for Erkan Ulu Schools and more, with screenshots and the current status of each.
