Is your business still managing accounting using Excel, manual records, multiple disconnected applications or paperwork?
As a business grows, financial management becomes increasingly complex.
You may need to track:
Sales
Purchases
Expenses
Invoices
Payments
Customers
Suppliers
Accounts receivable
Accounts payable
Cash flow
Bank transactions
Taxes
Payroll-related information
Financial reports
When these records are maintained in different places, it becomes difficult to get an accurate picture of your business.
This is where accounting software can help.
At WATT-IF LTD, we develop custom accounting software and financial management systems designed around your business processes, reporting requirements and existing systems.
💰 Ready to Digitize Your Business Accounts?
WATT-IF can develop an accounting system for income, expenses, invoices, payments, customers, suppliers, financial reports and integrations with other business systems.
[Request an Accounting System Consultation]
Accounting software is a digital system that helps a business record, organize and report its financial transactions.
A basic accounting workflow might look like:
Sale
↓
Invoice
↓
Payment
↓
Accounting record
↓
Financial report
A more advanced system can connect accounting with:
Invoicing
POS
Inventory
CRM
Payroll
M-Pesa
Banking
E-commerce
Procurement
This allows financial information to flow between different business operations.
Imagine your business makes:
100 sales per month
and has:
50 expenses
plus:
20 suppliers
and:
100 customers.
If every transaction is entered manually into spreadsheets, your accounting team has to constantly reconcile information.
An integrated accounting system can centralize the information.
Instead of asking:
"How much money did we make this month?"
management can use reports generated from the system.
Depending on the scope, WATT-IF can develop accounting functionality covering:
Chart of accounts
General ledger
Income
Expenses
Sales
Purchases
Invoicing
Receipts
Customer accounts
Supplier accounts
Accounts receivable
Accounts payable
Cash management
Bank reconciliation
Tax-related records
Financial reports
Budgets
User permissions
Audit trails
Integrations
The exact modules depend on the organization's requirements.
The chart of accounts provides the structure used to categorize financial transactions.
For example:
Cash
Bank
Accounts receivable
Inventory
Equipment
Accounts payable
Loans
Other obligations
Product sales
Service revenue
Other income
Rent
Salaries
Internet
Marketing
Transport
A custom accounting system can be configured around the organization's accounting structure.
The general ledger provides a central record of financial transactions.
Transactions from different modules can feed into the accounting system.
For example:
Invoice
↓
Customer account
↓
Accounts receivable
↓
General ledger
This can reduce duplicate data entry.
The system can record different sources of business income.
For example:
Product sales
Service revenue
Subscription income
Consulting
Other business income
Management can then analyze income by period, branch, product or service.
Businesses have many expenses.
Examples include:
Rent
Salaries
Utilities
Internet
Transport
Advertising
Office supplies
Software subscriptions
Professional services
An expense module can allow authorized users to record and categorize these transactions.
For organizations with multiple employees, expenses may need approval.
A workflow could be:
Employee
↓
Expense request
↓
Manager
↓
Finance
↓
Approved
↓
Payment
This can create a more structured process.
Businesses often need supporting documents for expenses.
A system can potentially allow users to upload receipts or other supporting documents.
For example:
Expense
KSh 15,000
↓
Receipt uploaded
↓
Approval
↓
Accounting record
The exact document storage and retention process should be designed around the company's requirements.
Accounting software can connect sales transactions with financial records.
For example:
Customer purchase
↓
Invoice
↓
Payment
↓
Revenue recorded
This can help reduce the need to enter the same transaction into multiple systems.
Your accounting system can be connected to the invoicing module.
For example:
Invoice created
↓
Accounts receivable
↓
Customer balance
↓
Payment
↓
Receivable reduced
This is one of the most useful integrations for businesses.
🧾 Already Using an Invoicing System?
WATT-IF can help assess how your invoicing and accounting systems can work together so that financial information does not have to be entered repeatedly.
[Discuss Accounting & Invoicing Integration]
Accounts receivable represents money customers owe the business.
The system can show:
Customer | Invoice | Amount | Paid | Balance |
|---|---|---|---|---|
Customer A | INV-001 | 100,000 | 60,000 | 40,000 |
Customer B | INV-002 | 50,000 | 50,000 | 0 |
Customer C | INV-003 | 80,000 | 0 | 80,000 |
This makes outstanding customer balances easier to monitor.
Businesses also owe money to suppliers.
The system can record:
Supplier
Invoice
Amount
Due date
Payments
Outstanding balance
For example:
Supplier invoice
↓
Accounts payable
↓
Approval
↓
Payment
↓
Balance updated
Supplier profiles can contain:
Supplier name
Contact details
Supplier number
Payment information
Purchase history
Outstanding balances
This gives finance teams a centralized supplier record.
A business purchasing products or services can track:
Purchase request
↓
Purchase order
↓
Supplier invoice
↓
Payment
↓
Accounting record
This can connect accounting with procurement.
The system can generate purchase orders containing:
Supplier
Items
Quantity
Price
Delivery information
Approval information
The purchase order can then be linked to the supplier invoice where required.
A business needs to know where its money is.
The system can track different accounts such as:
Cash
Bank account
Mobile money
Petty cash
This can help management understand available funds.
For Kenyan businesses, mobile money can be an important part of financial operations.
A possible workflow is:
Customer
↓
M-Pesa payment
↓
Payment confirmation
↓
System
↓
Customer invoice updated
↓
Accounting record
The exact implementation depends on the relevant payment API and business requirements.
📱 Want to Connect M-Pesa to Your Accounting Workflow?
WATT-IF can assess your payment process and develop applicable API integrations so transactions can flow into your business systems.
[Discuss M-Pesa Integration]
Businesses accepting card payments can potentially connect their payment provider with the accounting workflow.
For example:
Customer pays by card
↓
Payment gateway
↓
Confirmation
↓
Invoice updated
↓
Accounting record
This reduces manual reconciliation.
Bank reconciliation is an important accounting process.
The basic idea is to compare:
Company accounting records
with
Bank transactions
and identify differences.
A system can be designed to support reconciliation workflows, depending on the available banking integration.
Where appropriate APIs or supported banking services are available, banking information can potentially be integrated into the accounting workflow.
For example:
Bank transaction
↓
Integration
↓
Accounting system
↓
Matching
↓
Reconciled transaction
Integration availability depends on the specific bank and service.
One of the biggest benefits of accounting software is reporting.
Reports can include:
Income statement
Balance sheet
Cash flow
Sales report
Expense report
Accounts receivable
Accounts payable
Customer statements
Supplier statements
Tax-related reports
Profitability reports
Reports should be configured according to the organization's accounting requirements.
Management needs to understand whether the business is profitable.
A profit-and-loss report can organize:
Revenue
minus
Expenses
equals
Profit/Loss
The exact accounting treatment depends on the organization's accounting framework.
Profit doesn't necessarily mean cash is available.
A business may have:
KSh 5 million in invoices
but only:
KSh 2 million collected.
Cash-flow reporting can help management understand actual cash movements.
Customers can receive statements showing:
Opening balance
Invoices
Payments
Adjustments
Closing balance
This can be particularly useful for businesses that offer customers credit.
Similarly, supplier statements can help finance teams track:
Purchases
Supplier invoices
Payments
Outstanding balances
Businesses can establish budgets for different areas.
For example:
Budget: KSh 500,000
Actual: KSh 430,000
Remaining: KSh 70,000
The system can compare budgets with actual transactions.
For larger organizations, financial information can be categorized by department.
For example:
Marketing
Sales
Finance
Operations
IT
Management can then analyze spending by department.
If your company has several branches, the system can separate transactions by location.
For example:
Nairobi
Mombasa
Kisumu
Nakuru
Management can view branch-specific reports or consolidated results.
Businesses with multiple legal entities may require separate accounting structures.
A custom system can potentially support multiple companies, subject to the project's accounting requirements.
Accounting data should not be accessible to everyone.
For example:
Can:
Record transactions
Reconcile accounts
Generate reports
Can:
Create invoices
View customers
Can:
Approve expenses
View reports
Can:
Manage users
Configure system settings
Permissions can be customized.
Financial systems need accountability.
An audit trail can record:
Who created a transaction
Who modified it
When it was changed
What action was performed
This can help organizations monitor system activity.
Management can have a financial dashboard displaying key information.
For example:
KSh 4.2M
KSh 2.8M
KSh 1.4M
KSh 800K
KSh 1.9M
KSh 350K
The exact dashboard depends on the business.
If your company sells products, accounting and inventory can work together.
For example:
Purchase
↓
Inventory increases
↓
Supplier payable
Then:
Sale
↓
Inventory decreases
↓
Customer invoice
↓
Revenue
This can provide a more connected view of operations.
For businesses using POS systems:
Customer purchase
↓
POS
↓
Payment
↓
Inventory update
↓
Accounting transaction
This can eliminate repeated data entry.
A CRM manages customer relationships.
Accounting manages financial transactions.
Connecting the two can create a workflow such as:
Lead
↓
Customer
↓
Sale
↓
Invoice
↓
Payment
↓
Accounting
This creates a more complete customer lifecycle.
An accounting module can become part of a larger ERP platform.
For example:
Sales
↘
Inventory → Accounting
↗
Purchasing
↘
HR
The ERP provides a centralized business system.
If you already have other software, we can develop APIs to connect systems.
For example:
Website
↓
API
↓
Accounting System
or:
POS
↓
API
↓
Accounting System
or:
M-Pesa
↓
API
↓
Accounting System
This is particularly useful for businesses with several systems.
We begin by understanding your accounting workflow rather than immediately writing code.
We identify:
Business structure
Revenue sources
Expenses
Customers
Suppliers
Payment methods
Bank accounts
Branches
Existing accounting software
Reporting requirements
We map how transactions move through the business.
For example:
Sale
↓
Invoice
↓
Payment
↓
Customer account
↓
General ledger
↓
Financial report
This ensures the software reflects the intended accounting workflow.
We design the database around the required financial records.
This can include:
Accounts
Transactions
Customers
Suppliers
Invoices
Payments
Expenses
Journals
Reports
We develop interfaces for:
Accounting dashboard
Sales
Purchases
Customers
Suppliers
Expenses
Payments
Reports
Settings
The system is developed to process transactions according to the agreed accounting rules.
This stage is especially important because accounting software must do more than simply display numbers.
Depending on requirements, integrations may include:
M-Pesa
Card payments
Banking
POS
Inventory
CRM
Invoicing
Payroll
E-commerce
APIs
We test different financial scenarios.
For example:
Sale
Payment
Refund
Expense
Partial payment
Supplier payment
Bank transaction
Adjustment
Invoice cancellation
We train relevant users.
Transactions, reconciliation and reports.
Approvals and financial analysis.
Invoices and customer information.
Dashboards and reports.
Users, permissions and system configuration.
The system can be deployed according to the agreed infrastructure.
This can include:
Hosting
Database
SSL
Backups
User accounts
Security configuration
After launch, your business may require:
Technical support
Bug fixes
New reports
New integrations
System updates
Performance improvements
Additional modules
WATT-IF can provide ongoing development and maintenance according to the agreed support arrangement.
There is no fixed price for custom accounting software.
A small accounting system may include:
Income
Expenses
Customers
Suppliers
Invoices
Payments
Basic reports
An enterprise system may include:
Full accounting
Inventory
Procurement
POS
CRM
Payroll
M-Pesa
Banking
Multiple branches
Advanced reports
Mobile application
APIs
These are very different projects.
More modules require more development.
A system designed for five users differs from one designed for hundreds.
M-Pesa, banking, POS, inventory and other integrations increase scope.
Basic reports require less development than advanced financial dashboards.
Multiple locations add additional requirements.
A dedicated mobile app requires additional development.
Unique accounting processes require additional analysis and development.
The timeline depends on the scope.
A basic accounting application is very different from a complete platform integrating:
Accounting
Invoicing
Inventory
POS
Payroll
CRM
M-Pesa
Banking
WATT-IF can provide a project timeline after the requirements have been assessed.
