Hey folks, I'm a developer gearing up to create a custom school management system for a client who will pay for the project upfront. This system is going to be quite comprehensive and will include features like student and staff management, attendance tracking, grading, timetable organization, financial components (tuition, invoicing, payment integration), and a parent communication app to keep everyone in the loop. I'm probably going to tackle this project solo or with a very small team, so I'm trying to nail down how to price it reasonably. I'd love some advice on a few things: 1. **One-time development cost**: What would be a fair price for a system like this? 2. **Monthly maintenance fee**: How much should I charge for support, bug fixes, and updates once it's done? 3. Any aspects I'm underestimating, especially concerning payment integration or scalability? Just a heads up, I'm not based in the US so my rates might be lower, but I want to make sure I price it right given the complexity involved. Thanks a bunch!

Honestly, you should consider the legal aspects too. If there's a data breach or some user info gets exposed, you'll want to be clear in your contract that the liability isn't solely on you. Just something to keep in mind as you draft your agreements.
For something like that, you might be looking at a starting budget of around $100k, and that’s just a ballpark. Don’t forget to factor in ongoing maintenance, which could be between $2k to $5k a month depending on the level of support needed.
You might want to break the project into milestones and request payment at each step instead of waiting for a lump sum at the end. I've found this approach super helpful, especially when managing client feedback and clarifications throughout the process. Also, ensure you have a written agreement that details both your responsibilities and the client's to avoid any misunderstandings later on. Good luck with your project!
Great tip, I hadn't considered that! Thanks for the advice!
This sounds like a massive undertaking. Have you thought about existing solutions that could help? Rather than building every feature from scratch, integrating established products might save you time and effort.
I see what you mean! We're actually looking to integrate some existing financial solutions, so we won’t be starting from square one.

Yeah, you may want to rethink those figures. A project of this size can easily climb into the hundreds of thousands.
