Example result
Desktop program: invoice maker for a one-person bookkeeping service
The windows
- Invoices: the list of past invoices with number, client, date and total; buttons New, Open and Save as PDF.
- New invoice: client from a drop-down list, lines with description, hours and rate, tax rate, and the total updated as you type.
- Clients: name, address and email, added once and picked from the list afterwards.
A part of the code
def update_total(self, *_):
"""Adds up the lines and the tax and shows the total under the table."""
subtotal = sum(line.hours * line.rate for line in self.lines)
tax = round(subtotal * self.tax_rate.get() / 100, 2)
self.subtotal_label.config(text=f"Subtotal: {subtotal:,.2f}")
self.tax_label.config(text=f"Tax: {tax:,.2f}")
self.total_label.config(text=f"Total: {subtotal + tax:,.2f}")
In the archive
invoice_maker.py, the program, about 700 lines;invoices.db, made on the first run, which keeps the clients and invoices;settings.example.inifor your name, address and invoice number format;requirements.txtwith the one extra library, reportlab, which writes the PDF;- README: how to install Python, start the program and build an .exe with PyInstaller.
The program runs on the client's own computer. We do not build installers, sign the program or publish it.
Client: a freelance bookkeeper who writes 20–30 invoices a month in a word processor. Task: a small program with a window: pick a client, add lines, see the total with tax, save the invoice as a PDF, and keep the list of clients. Standard package: up to 3 windows and 800 lines, data in SQLite.
The client and all details are made up.
About this service
A to-do list that lives on your computer rather than in an online account: open it, add a task, set a date and tick it off when it is done. It is a typical ready-made program that we adapt with your details: the labels in your language, your lists or categories, the colours and the window title. Basic is a quick list for the day that is cleared when you close it; from Standard tasks are saved in CSV or SQLite with due dates, priorities and a view of what is due today; in Premium you add projects, repeating tasks, search, export to a file and an error log. We write it in Python with Tkinter, with a README. It does not sync with your phone or online calendars and sends no notifications while closed: it shows what is due when you open it.
What is included
- What you getA ZIP archive with the Python code of the ready program adapted with your details, a README on installing Python, running it and building an .exe, and the code shown on the order page. From Standard, tasks saved to CSV or SQLite; in Premium, projects, export to a file and an error log.

What we need from you
Your lists or categories, what a task should have (a date, a priority, a note, a project), how tasks are sorted, the language of the labels, the window title, your colours if you like, your system (Windows, macOS or Linux) and whether you want an .exe.

Questions and answers
Will my tasks be saved?
From Standard, yes, in a CSV file or an SQLite database on your computer. Basic keeps the list only while the program is open.
Does it sync with my phone or calendar?
No. It works offline on one computer. Premium can export tasks to a file that you open elsewhere.
Will it remind me of tasks?
It shows what is due when you open it. It sends no notifications while it is closed.
Is it written from scratch for me?
No. It is a ready-made, typical to-do list that we adapt with your details, which is why it costs less. A very different program fits the made-to-order desktop program service better.
Will I get an installer or a signed program?
No. You get the code and the steps to build an .exe yourself with PyInstaller. We do not build installers, sign the program or publish it anywhere, so Windows or macOS may warn you the first time you open it.
