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
For a household, a freelancer or a small club that wants to see where the money goes without giving bank logins to an app. You enter what you spent, pick a category, and the program adds it up by category and month. It is a typical ready-made program that we adapt with your details: your categories, currency, labels in your language and colours. Basic shows totals while it is open; from Standard expenses are saved in CSV or SQLite with monthly totals and a budget per category; in Premium you add income, simple charts, import of a CSV statement you download from your bank, export and an error log. We write it in Python with Tkinter, with a README. It records only what you enter: it does not connect to banks, give financial or tax advice or replace accounting software.
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, expenses saved to CSV or SQLite; in Premium, income, charts, bank CSV import, export and an error log.

- 4ChangesYou ask for changes within your package and send any error message
What we need from you
Your categories, currency and language; whether you want budgets per category; for Premium, a sample of your bank's CSV statement with amounts and names changed, so the import reads the right columns; your colours if you like; your system (Windows, macOS or Linux) and whether you want an .exe. Never send bank logins, passwords or card numbers.
We will ask you:
- Your categories
- Currency and language
- Budgets
- Which system will it run on?

Questions and answers
Does it connect to my bank?
No. It never asks for bank logins. In Premium you can import a CSV statement that you download yourself.
Can a business use it for its accounts?
It is a simple record of spending, not accounting software, and it does not prepare tax returns. Ask your accountant what your business needs.
Will my data be saved?
From Standard, yes, in a CSV file or an SQLite database on your computer. Basic keeps entries only while it is open.
Is it written from scratch for me?
No. It is a ready-made, typical expense tracker 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.
