Home Tutor Lesson Log and Monthly Invoice with Rates, Travel and

Home Tutor Lesson Log is an offline app (one HTML file in a zip) for a private tutor who travels to students. You enter each student with the parent's number and an hourly rate that can change from a date, then log every lesson with its date, start time and length. The app prices each lesson, applies your cancellation rules, keeps the running balance after payments, and prints a monthly invoice with every lesson on it.

The problem it removes: A tutor who invoices from memory gets the lesson count wrong, and a parent who remembers fewer lessons disputes the whole month. Rates change, lessons are moved, some are cancelled at the door, and the tutor owes a make-up lesson that nobody wrote down. This app records each lesson as it happens, shows the parent the date and time of every lesson on the invoice, and keeps track of what is paid and what is still owed.

What is inside:

• Lesson log with date, start time, length and a status: Planned, Held, Make-up, Late cancel, No answer at door, Cancelled in time or Cancelled by tutor
• Hourly rate and travel fee per student with a start date, so a rate rise in September never changes August
• Late cancel and no answer charges worked out with your own percentages, and make-up lessons owed after a tutor cancellation
• Monthly invoice that lists every lesson with its date, time and charge, the amount brought forward, payments and the amount due
• Month view with lessons, hours, billed, collected, who owes money, who needs last month's invoice and a week calendar of planned lessons
• One button to make last month's invoices for every student who had lessons, plus payment receipts and a clash check on your own diary
• Example data you can load in one click, a Start here guide and an Honest limits panel
• JSON backup and restore, CSV export, and CSV import with a check of every row before anything is added

Who it is for: private tutors and small tutoring teams who teach at the student's home, bill by the hour and want parents to see exactly which lessons they are paying for.

What it is NOT: It is not the monthly flat fee and attendance register for a tuition centre (the Tutor and Small School Fee and Attendance Tracker covers that). It has no grades, no parent login, no online payment and no tax calculation. It does not send messages by itself: it opens WhatsApp with the text written. It is not legal, tax or accounting advice, it is not connected to any government system, bank or messaging service, and it does not file or send anything by itself. UAE e-invoicing is not part of it.

Verified by us: scripted tests in Chromium (173 checks through the real screens: adding, editing and deleting records in every table, required-field messages, backup then clear then restore, CSV export then import, keyboard order, print layouts rendered to PDF, no horizontal scrolling at 375 and 1280 pixels, no network requests) and an independent recalculation by a separately written Python evaluator of 4640 calculated values (25 randomised rows plus the example data) with 0 mismatches.
