1. Install Bexbox on your phone

Bexbox runs on Android phones. You install it from the Google Play Store, the same way you install any other app. There is no separate download from a website.

  1. On your phone, open the Play Store app.
  2. Type Bexbox in the search bar at the top.
  3. Tap Install. It is about the size of a typical app and downloads in under a minute on Wi-Fi.
  4. When the install is done, tap Open.
In short: Play Store, search "Bexbox", tap Install, then Open.

2. Sign in for the first time

The first time you open Bexbox you see a short welcome tour. You can flick through it or tap Skip all at the bottom-left. Either way you land on the sign-in screen.

The first screen you see: a short welcome tour. Tap Skip all if you just want to get going.

You have two ways to sign in:

Whichever you pick, that account is the owner of every record you create. Use one you will remember and keep access to.

Why GoogleIt is faster, more secure, and you cannot lose access to your records because you forgot a password. Bexbox only sees your name and email; it cannot read your Gmail.

3. Find your way around the app

After you sign in, the app drops you on the Dashboard. The Dashboard is your one-glance summary: how much people owe you, how much you owe other people, and the recent activity.

At the bottom of every screen there is a row of small icons. These are the tabs. From left to right they take you to:

The Dashboard. Your net position and outstanding balances sit on top; recent activity is below.
Tip: The middle tab (Dashboard) is your home base. If you ever get lost, tap it.

4. Add your first contact

In Bexbox, every transaction is attached to a contact. A contact is just a person you exchange money with: a friend, a family member, a roommate, a customer.

You do not need their phone number or email. A name is enough.

  1. Tap the Contacts tab (leftmost icon at the bottom).
  2. Tap the + button. On most phones it is a green circle in the bottom-right corner.
  3. Type the contact's name. That is the only required field.
  4. (Optional) Add a phone number or a photo. Useful but not needed.
  5. Tap Save.

The Contacts tab. Hit the + button to add your first one.
Bexbox Add Contact form with name field
The Add Contact form. Only the name is required.
Heads upA contact starts off private. Only you can see it. If later you want the other person to share the same ledger, that is a separate step covered in section 9.

5. Log your first transaction

A transaction is one entry that records money moving in or out. "I covered Maria's $25 lunch" is a transaction. "Maria paid me back $10" is another transaction.

  1. Tap the contact you want to log a transaction for. This opens the contact's screen, where their running balance lives.
  2. Tap the + button to add a new transaction.
  3. Choose I gave (you paid for them or lent them money) or I received (they paid you back, or owed you and now do not).
  4. Type the amount, for example 25.00.
  5. Set the date. You can also add an optional due date to get a reminder later.
  6. Pick a category like Food, Rent, Utilities. Picking a category helps the reports later.
  7. (Optional) Add a note and any proof attachments (covered in the next section).
  8. Tap Save and Lock.
Bexbox Add transaction form with I gave selected, amount, date, due date, category, note, proof, Save and Lock
The Add transaction form. Pick I gave or I received, type the amount, fill in the rest, then Save and Lock.
In short: Open the contact, hit +, pick I gave or I received, type the amount, tap Save and Lock.

6. Attach a receipt, photo, or signature

Bexbox is built around proof. Every transaction can carry photos, PDFs, and supporting documents. This is what makes the record defensible: months from now, you can point at the actual receipt instead of relying on memory.

On the Add transaction form, scroll down to the Proof section. You will see three buttons:

Bexbox attachment options inside a transaction: Camera, Gallery, Document
Camera, Gallery, Document. Attach any combination, then Save and Lock.
Important: attachments are permanentOnce a transaction is saved and locked, its attachments cannot be removed individually. This is on purpose: it stops anyone from quietly changing a record after the fact. To remove an attachment you have to soft-delete the whole transaction (next section).

7. Fix or remove a transaction

Transactions are read-only after you save them. That sounds strict, but it is what makes the ledger trustworthy. To fix a mistake, you have two options.

Option A: Add a correcting entry

If you typed $25 instead of $20, add a new transaction in the opposite direction for $5. Now the running balance is right and the history shows what actually happened.

Option B: Soft-delete the transaction

  1. Open the transaction.
  2. Tap the menu (three dots), then Delete.
  3. Bexbox asks you for a reason. Type something honest like "wrong amount" or "duplicate entry".
  4. Tap Confirm. The transaction drops out of the balance but stays in the audit trail and in your full ZIP export.

The reason field is required. It is the difference between a clean fix and a quiet edit.

8. Read the reports

Tap the Reports tab. You will see a few cards, each one a different angle on your data.

At the top of Reports you can switch between This Month, 30 days, Year, or Custom.

9. Invite a contact to share a ledger

So far the contact has been private. Only you see it. You can also send the other person an invite to join, so they can see the ledger from their side.

  1. Open the contact you want to share with.
  2. Tap Invite to share for a sharable link, or Show QR code for an in-person invite.
  3. Send the link on WhatsApp, Messenger, SMS, or email; or have the other person scan the QR code with their phone.
  4. The other person opens the link or scans the code, signs in to Bexbox if they are not already, and taps Accept.

Cancel an inviteIf you sent an invite by accident, open the contact and the share option will show Cancel invite. It works any time before the other side accepts.

10. Use the IOU calculators

The IOU Tools tab has four small calculators. None of them save anything by themselves. You can copy the result into a real transaction on a contact when you are happy with it.

Split Bill

You paid the whole bill. Split it evenly across two or more people, or by share if some people ordered more.

Debt

Plan how a debt gets paid off. Type the principal, set the interest (None or Fixed), pick a due date, and log partial payments. The calculator shows total payable, total paid, and the remaining balance at a glance.

APR Calculator

Type the loan amount, the APR percent per year, and the duration (in years or months). The calculator returns your monthly payment, total interest, and total payable. Useful for comparing two loan offers.

  1. Tap the Settings tab.
  2. Tap Default currency.
  3. The picker has every ISO 4217 currency. Type a code like USD, PHP, EUR, GBP, or a name like Philippines.
  4. Tap your choice. The whole app rebuilds with the new currency symbol.

  1. Tap Settings.
  2. Tap App lock.
  3. Turn on Require unlock. Bexbox will use whichever biometric is already on your phone (fingerprint or face).
  4. Set a 4 to 8 digit PIN as fallback for when biometrics are not available.
  5. From now on, Bexbox will ask before showing anything after 30 seconds in the background.

  1. Tap Settings.
  2. Tap Export your data.
  3. Bexbox builds a ZIP with transactions.csv, contacts.csv, and an attachments folder with every proof image, video, PDF, and signature. Soft-deleted transactions are included so the audit trail is complete.
