The Dashboard is the first screen you see after logging in. It shows a real-time snapshot of your business โ€” all key numbers in one place so you can make quick decisions without digging into reports.

Dashboard Summary Cards

Today's Sales

Total invoice value of all sales created today (paid + unpaid).

Cash in Hand

Total cash received from sales and payments, minus cash expenses and withdrawals.

Top Customers

The Top Customers section shows the 5 customers with the highest purchase value in the current month. Tap any customer name to open their full ledger โ€” all their invoices and payment history.

โœ… Tip: All amounts on the dashboard are live โ€” they update the moment you save a new invoice or payment. There is no need to refresh manually.

๐Ÿงพ

3. Sales Invoicing

Create GST invoices, collect payment, and share with customers

CerebraQ ERP generates fully compliant GST invoices with CGST, SGST, and IGST support. Invoices are auto-numbered and can be shared as PDF via WhatsApp or email.

Creating a New Sales Invoice

  1. 1

    Go to Sales โ†’ New Invoice

    Tap the "+" button on the Sales screen or tap New Invoice from the main menu.

  2. 2

    Select the Customer

    Tap the Customer field and search by name or phone. If the customer is new, tap "Add New Customer" to create them on the spot โ€” no need to go to the Parties screen first.

  3. 3

    Add Items

    Tap "Add Item", search for a product, enter the quantity. The unit price and HSN code are auto-filled from your product catalogue. Repeat for each item in the order.

  4. 4

    Set GST Type

    Select the applicable GST type:
    CGST + SGST โ€” for sales within the same state (intra-state).
    IGST โ€” for sales to a buyer in a different state (inter-state).
    The app may auto-detect this based on your state vs the customer's state if the customer's GST state is set.

  5. 5

    Apply Discount (optional)

    Enter a flat discount amount (e.g. โ‚น50) or a percentage (e.g. 5%) in the Discount field. The discount is applied before GST calculation.

  6. 6

    Select Payment Type

    Choose Cash, UPI, or Card. For partial payments, see the Payment Status field below.

  7. 7

    Set Payment Status

    Choose the payment status:
    Paid โ€” Full amount received. Updates Cash in Hand or Bank Balance accordingly.
    Partial โ€” Enter the amount received. The remaining balance is tracked as a receivable in the customer's ledger.
    Unpaid โ€” Full amount outstanding. Entire invoice amount goes to receivables.

  8. 8

    Save & Generate PDF

    Tap "Save Invoice". A PDF is instantly generated. You'll see buttons to Print, Share via WhatsApp, or Send via Email.

What's on the GST Invoice PDF?

Sharing via WhatsApp

  1. 1

    After saving the invoice, tap "Share WhatsApp".

  2. 2

    WhatsApp opens with the customer's phone number pre-filled (if stored in the customer record). The invoice PDF is attached.

  3. 3

    Tap Send in WhatsApp. The customer receives the PDF instantly.

๐Ÿ’ก Tip: Always save the customer's WhatsApp number in their profile. This way sharing invoices takes just one tap โ€” no typing needed.

Editing or Cancelling an Invoice

  • โ€ขEdit: Go to Sales, find the invoice, tap the Edit icon. You can modify items, discount, and payment details. Editing regenerates the PDF with the same invoice number.
  • โ€ขCancel: Tap the invoice โ†’ tap Cancel Invoice. A cancelled invoice is retained for audit purposes but is excluded from all sales totals. Stock is reversed automatically.

โš ๏ธ GST Compliance: If you have already shared an invoice with a customer and need to correct it, cancel the original invoice and create a fresh one with a new invoice number. Do not edit an invoice after it has been shared, as this can cause reconciliation issues.

๐Ÿ›’

4. Purchase Management

Record purchases from vendors, track payables, manage stock

Every time you buy goods from a vendor, record it as a Purchase Bill in CerebraQ ERP. This automatically updates your inventory stock levels and adds the amount to your payables if not fully paid.

Recording a Purchase

  1. 1

    Go to Purchases โ†’ New Purchase

    Tap "New Purchase" or the "+" button on the Purchases screen.

  2. 2

    Select the Vendor

    Search for your vendor by name. If new, tap "Add New Vendor" to add them quickly.

  3. 3

    Enter Vendor's Invoice Details

    Enter the vendor's invoice number and invoice date from their physical bill. This helps in reconciliation during GST filing.

  4. 4

    Add Purchased Items

    Tap "Add Item" and select the product. Enter the quantity and purchase price (rate). The app adds the purchased qty to your current stock automatically upon saving.

  5. 5

    Set Payment Status

    Paid โ€” You have already paid the vendor. Partial โ€” Enter the advance/partial amount paid. Unpaid โ€” Full amount is payable. All outstanding amounts appear under your Payables on the dashboard.

  6. 6

    Save Purchase Bill

    Tap Save. Stock levels are updated instantly. The vendor's outstanding balance is updated in their ledger.

Vendor-Wise Purchase History

To view all purchases from a specific vendor:

  1. 1. Go to Parties โ†’ Vendors and tap the vendor's name.
  2. 2. The vendor ledger opens showing every purchase bill, payment made, and outstanding balance.
  3. 3. Tap any purchase entry to view its full details.

โœ… Stock Auto-Update: You do not need to manually update stock after recording a purchase. CerebraQ ERP adds the purchased quantity to the product's current stock the moment you save the purchase bill. Similarly, when you create a sales invoice and mark it as delivered, the sold quantity is deducted from stock.

๐Ÿ“ฆ

5. Inventory & Products

Add products, manage stock levels, get low-stock alerts

Adding a New Product

  1. 1

    Go to Inventory โ†’ Products and tap "Add Product".

  3. 3

    Enter the Opening Stock โ€” the quantity currently in stock before you start recording purchases through the app.

  4. 4

    Tap Save. The product is now available in Sales Invoicing and Purchase Management.

  • โ€ขShow a red badge on the Inventory menu icon in the sidebar.
  • โ€ขList the product under Inventory โ†’ Low Stock tab.
  • โ€ขDisplay a warning on the Dashboard summary if more than 3 items are low.

Manual Stock Adjustment

  1. 1

    Go to Inventory โ†’ Stock Adjustment.

  2. 2

    Select the product and enter the Adjusted Quantity (the correct current stock, not the difference).

  3. 3

    Add a Reason (e.g. "Physical count correction", "Wastage", "Theft"). Tap Save.

๐Ÿ‘ฅ

6. Customers & Vendors

Manage party ledgers, outstanding balances, and payment reminders

CerebraQ ERP maintains a complete running ledger for every customer and vendor. You can see their entire transaction history, outstanding balance, and send payment reminders โ€” all from the Parties screen.

    Go to Parties โ†’ Customers โ†’ Add Customer.

  2. 2

    Fill in the customer's Name (required), Phone, Address, and GSTIN (if they are a GST-registered business).

    Enter their state โ€” this is used to auto-detect CGST+SGST vs IGST on invoices.

  4. 4

    Optionally set a Credit Limit (โ‚น amount) โ€” the app will warn you if a new invoice would exceed this limit.

  5. 5

    Tap Save. The customer is now selectable in all Sales Invoices.

Adding a Vendor

The process is the same as adding a customer. Go to Parties โ†’ Vendors โ†’ Add Vendor. Enter the vendor's name, phone, address, and GSTIN. The vendor will be available in Purchase Management.

    Open the customer's ledger โ†’ tap "Receive Payment".

  2. 2

  1. 1

    Open the customer's ledger. Tap "Send Reminder".

  2. 2

    A pre-composed WhatsApp message is generated with the customer's name, outstanding amount, and a list of overdue invoices. Edit the message if needed.

  3. 3

    Tap Send via WhatsApp. WhatsApp opens with the message pre-filled to the customer's phone number.

๐Ÿ’ก Tip: Store your customers' WhatsApp numbers when adding them to the app. This makes both invoice sharing and payment reminders a one-tap operation.

๐Ÿ’ธ

7. Expense Tracking

Record and categorize all business expenses

Tracking expenses in CerebraQ ERP ensures your Profit & Loss report reflects the true profitability of your business โ€” not just gross sales minus purchases, but net profit after all operating costs.

    Select the Category (see list below).

CerebraQ ERP supports Hindi (เคนเคฟเค‚เคฆเฅ€), Marathi (เคฎเคฐเคพเค เฅ€), and English. You can switch the app language at any time from the Settings screen. The change takes effect immediately โ€” no restart required.

How to Change the App Language

  1. 1

    Open Settings

    Tap the Settings icon in the navigation bar (usually the gear icon โš™๏ธ at the bottom or in the sidebar).

  2. 2

    Tap "Language"

    In the Settings screen, find the Language option.

๐Ÿ‡ฎ๐Ÿ‡ณ

๐Ÿ”„

10. Sync & Offline Mode

Work without internet โ€” your data syncs automatically when you're back online

CerebraQ ERP is designed for Indian business conditions where internet connectivity may not always be reliable. The app stores all your data locally on the device and syncs with the cloud whenever internet is available.

How Offline Mode Works

๐Ÿ“ด

No Internet? No Problem.

All core features โ€” creating invoices, recording purchases, managing inventory, adding customers โ€” work 100% offline. Nothing is blocked or disabled.

๐Ÿ’พ

Data Stored Locally

Every entry is immediately saved to the device's local storage. You will never lose data because of a lost internet connection mid-entry.

โ˜๏ธ

Auto-Sync When Online

As soon as internet is restored, the app automatically syncs all pending entries to the cloud server. No manual action is required.

๐Ÿ“ฑ๐Ÿ’ป

Cross-Device Sync

After syncing, data is available on all your devices โ€” invoices created on Android appear on the Windows app and vice versa.

Checking Sync Status

  • โ—
    Green dot / "Synced": All local data has been successfully uploaded to the cloud. Both devices are in sync.
  • โ—
    Yellow dot / "Pending sync": There are entries recorded offline that are waiting to be synced. Internet is currently unavailable.
  • โ—
    Red dot / "Sync error": Sync attempted but failed (e.g. login session expired). Tap the icon to retry or re-login.

Manual Sync

If you want to force a sync immediately (e.g. before handing off to another device):

  1. 1

    Ensure you have an active internet connection.

  2. 2

    Go to Settings โ†’ Sync โ†’ Sync Now (or tap the sync icon in the status bar).

  3. 3

    Wait for the green "Synced" confirmation. This usually takes a few seconds.

โš ๏ธ Conflict Resolution: If the same record (e.g. a customer) is edited on two devices while both are offline, the change saved most recently (by timestamp) will be kept after sync. To avoid conflicts, try to use one primary device for editing master data (products, parties) and only create transactions (invoices, purchases) on the secondary device.

โœ… No data loss guarantee: CerebraQ ERP maintains a local transaction queue. Even if the app is closed during a sync, unsynced entries are preserved and will be synced the next time the app is opened with an active connection.

11. Frequently Asked Questions

Quick answers to common questions about CerebraQ ERP

Does CerebraQ ERP work without internet? +
Yes. CerebraQ ERP works fully offline. You can create invoices, record purchases, manage inventory, and track expenses without any internet connection. When internet is restored, all data syncs to the cloud automatically. There is no manual action needed.
Can I use the same account on both Android and Windows? +
Yes. One account covers both platforms. Log in with the same credentials on your Android phone and your Windows PC. Data syncs between them automatically when both devices are online. Invoices, customer records, and inventory are shared across devices.
Are the invoices legally valid GST invoices? +
Yes. CerebraQ ERP generates Tax Invoices that comply with GST invoice requirements under Indian GST law โ€” including your GSTIN, the customer's GSTIN, HSN codes, item-wise GST breakup (CGST/SGST/IGST), taxable value, and invoice serial number. The format is accepted by GST portals and can be used for GSTR-1 filing.
How do I find a customer's HSN code for my products? +
The HSN (Harmonized System of Nomenclature) code for a product is assigned by the GST council based on the product type. You can look up HSN codes on the GST Council website or ask your CA. Once added to a product in CerebraQ ERP, the HSN code auto-fills on every invoice for that product.
Where is my data stored? Is it safe? +
Your data is stored locally on your device (phone or PC) and backed up to a secure cloud server when internet is available. Cloud backups are encrypted. Even if you lose your phone, your data is recoverable by logging into the app on a new device โ€” it will sync all your data from the cloud.
Can I add multiple users to the ERP (e.g. owner + accountant)? +
Multi-user support depends on your plan. On the Standard plan, one user account is included. If you need additional user accounts (e.g. for an accountant, sales staff, or branch manager), contact us โ€” we offer multi-user licensing options. Additional users can have restricted access (e.g. sales-only, view-only for reports).
How do I record a payment against an existing outstanding invoice? +
Go to Parties โ†’ Customers, tap the customer's name to open their ledger, then tap "Receive Payment". Enter the amount received, payment mode, and date. The payment is applied against the oldest outstanding invoice first, and the customer's balance is updated immediately.
What is the difference between CGST+SGST and IGST? +
CGST + SGST applies to intra-state sales โ€” when you and your customer are in the same state. The total GST is split equally: half goes to the Central Government (CGST) and half to the State Government (SGST).

IGST applies to inter-state sales โ€” when you sell to a customer in a different state. The entire GST goes as IGST to the Central Government, which then distributes it to the destination state.

CerebraQ ERP can auto-detect which to use based on your registered state vs the customer's state, or you can select it manually on each invoice.
Can I set different GST rates for different products? +
Yes. Each product in CerebraQ ERP has its own GST rate field. You can set 0%, 5%, 12%, 18%, or 28% per product based on its GST slab. When multiple products with different GST rates are on the same invoice, the app calculates the GST for each line item separately and shows a combined tax summary at the bottom.
I forgot my login password. What do I do? +
Tap "Forgot Password" on the login screen and follow the instructions to reset via email or phone OTP. If you are still unable to access your account, contact our support team at sales@cerebraq.com or WhatsApp us with your registered details โ€” we'll help you recover access.
How do I generate a P&L report to share with my accountant? +
Go to Reports โ†’ Profit & Loss. Set the date range (e.g. 01 Apr โ€“ 31 Mar for a financial year). Tap "Export PDF" or "Export Excel". Share the file directly with your CA via WhatsApp or email. The P&L report includes total sales, total purchase cost, expense-wise breakup, and net profit/loss.
What happens to my data if I change my phone? +
No data is lost. Install CerebraQ ERP on your new phone using the same APK, log in with the same account credentials, and the app will sync all your data โ€” invoices, customer records, products, and more โ€” from the cloud to the new device. The sync typically takes a minute or two depending on data volume and connection speed.
