Custom business software and internal tools
I build the small, specific tool your team keeps working around: a CRM shaped like your sales process, an inventory and quoting system, an invoicing flow, a dashboard over your real numbers. It replaces spreadsheets, WhatsApp threads and SaaS plans you only use 10% of. You get a fixed price before work starts.
What is included
- A short discovery call, then a written scope of what the tool does and what it does not
- Data model and screens built around your actual workflow, not a generic template
- Import of your existing spreadsheets or exports so you start with your data
- Roles and logins, so staff only see what they should
- Reports and exports your accountant or manager can use
- Hosting setup, backups and a handover walkthrough
Who this is for
- Teams running on Excel, Google Sheets or WhatsApp that have outgrown it
- Businesses paying per seat for a CRM or ERP where most features go unused
- Owners who need quotes, stock, jobs or reminders tracked in one place
How pricing works
You get one fixed price for the whole build, agreed before I start. After handover, optional monthly maintenance covers updates, fixes and small changes. If you would rather run it yourself, you get the code and a handover walkthrough instead.
Questions people ask
How do I know a custom tool is better than buying software?
Often it is not. If an off-the-shelf product fits your process, buy it. A custom build makes sense when you keep paying for features you do not use, or when your process is unusual enough that you work around the software every day. I will tell you in the first call if I think you should buy.
Can you move my existing spreadsheet data in?
Yes. I import from Excel, CSV or Google Sheets and clean obvious problems such as duplicates and inconsistent names, so you can check the result before anything goes live.
Who owns the code?
You do. I hand over the source code and the hosting accounts at the end of the project, so you are not locked in to me.
What happens if I need changes later?
Small changes fit inside the optional monthly maintenance. Bigger additions get their own fixed quote, the same way the first build did.
