What Private Tutors Track Daily

Track tutoring sessions

Log every lesson after class so you can see what happened, what was covered, and how many credits remain.

Lesson credits tracker

Keep a visible lesson credits tracker for prepaid bundles, make-up sessions, and package deductions across store credit, visit, and session modes.

Student progress notes

Save a short tutoring record app style note after each session so student history stays clear over time.

How Custly solves private tutor problems

The main job is not just to track lessons. It is to reduce errors, make packages easy to manage, and help a small tutoring business stay organized without turning into a full CRM.

Problem: balances are hard to rememberSolution: each student has a clear remaining balance and package history, so no one needs to guess.
Problem: cash is collected offlineSolution: take payment in person, then record the recharge in the app after the sale.
Problem: tutors work on the moveSolution: offline mode lets you update records even when there is no signal or Wi-Fi.
Problem: students ask for proofSolution: QR code access lets them check balance and consumption details themselves.

How Custly Fits the Workflow

1. Create the shop and choose a balance model

Set up the store first, then pick Store Credit, Visit, or Session so the app matches how you sell tutoring time.

2. Add the customer and recharge package

Create a student profile, then use a recharge package to add value after the student pays you offline.

3. Use a deduction template after each lesson

Apply a deduction template when a lesson finishes, so the tracker updates the balance and history in one step.

4. Review the timeline, export data, and sync if needed

Open the timeline in the private tutor app, export your data for reporting, and sync to the cloud when you use multiple devices.
