📚 Why Automate? (Educational Resources)

The Problem with Spreadsheets

Manual billing and Excel sheets often lead to:

Silent Mistakes: Formula errors can alter financial totals unnoticed.
Messy Data: Difficulty tracking active vs. cancelled accounts.
No Visibility: Lack of clear metrics for MRR or Churn.
Scaling Issues: More customers = more admin work.

How Payvo.me Solves It

Map Your Offers: Define monthly retainers, memberships, or installments once.
Migrate Profiles: Move from "spreadsheet rows" to dynamic Customer Profiles.
Automate Status: Payment status updates instantly; no more manual "Paid/Unpaid" toggling.
Real-Time Dashboards: Replace custom formulas with built-in graphs for Revenue and Retention.

Decision Framework

When choosing software, Payvo.me advises small businesses to check:

Payment Support: Does it handle your specific mix of one-time vs. recurring?
Complexity: Can non-technical team members use it?
Visibility: Do you get immediate insight into revenue?

🏁 Workflow: How to Start

Setup: Create an account at Payvo.me.
Onboarding: Input customer data and define billing plans.
Operations: Use the POS to scan items or manually log external payments.
Tracking: View reports on revenue, reconcile cash drawers, and manage payroll.

from HadiDB.operation import User
user = User("admin", "admin")
user.createUser() # Creating a new user in the HadiDB
user.authentication() # Authenticating the HadiDB user

Result:

{'status': 200, 'message': 'Database user Created'}

Create Databse , Collection and Schema

This code sets up user credentials and a schema for a database collection. It initializes a database operation using the Operation class with the specified username, password, database, and collection. Finally, it inserts the provided data into the collection and stores the result.

from HadiDB.operation import Operation

username = "admin"
password = "admin"
database = "mefiz.com"
collection = "authUser"

schema = {
    "username":"Unique",
    "password":"Hash",
    "cnic":"Unique",
    "picture":"Image",
    "bio":"Text"
}
db = Operation(username,password,database,collection)
db.create_database(schema)

Insert Data

Insert Data into the Collection use db.insert(data) inserts the data into the specified database collection.

from HadiDB.operation import Operation

username = "admin"
password = "admin"
database = "mefiz.com"
collection = "authUser"


db = Operation(username,password,database,collection)

data = {
    "username":"hadidb",
    "password":"12345",
    "cnic":"123232442",
    "picture":"user/my/hadidb.jpg",
    "bio":"HadiDB is the Best ;)"
}


result = db.insert(data)
print(result)

Result:

{
'status': 200, 
'message': 'Data insert successfully',
'data': {
    'username': 'hadidb', 
    'password': '12345',
