Sydex is a modern billing and business management app built for Indian businesses — whether you create GST invoices or simple non-GST invoices.

Create invoices, quotations, manage customers, track payments, handle inventory, record expenses, manage suppliers and keep clean business records from one simple mobile app.

Sydex is designed for Indian businesses of every size — from independent owners and growing teams to established traders, distributors and service companies that want billing, inventory, payments and records to stay clear, organised and professional.

PROFESSIONAL BILLING

Create GST and non-GST invoices with customer details, item details, discounts, shipping, tax details where applicable, HSN/SAC codes and payment information.

Add your logo, signature and stamp. Choose invoice themes and share professional PDFs through WhatsApp, email or any sharing app.

Add complete bank details on PDFs, including IFSC, branch, SWIFT, MICR and UPI, so customers get clear payment information.

QUOTATIONS

Create quotations before confirming an order. Add products, services, GST where applicable, notes, terms and validity details.

Once confirmed, convert the quotation into an invoice without entering the same details again.

CUSTOMERS, SUPPLIERS & INVENTORY

Keep customer and supplier records organised with contact details, GSTIN where applicable, addresses and business information.

Manage products and services with SKU, HSN/SAC, GST rate where applicable, price and stock quantity.

Stock updates automatically when invoices are created. Low stock alerts notify you when products are running low, so you can reorder on time.

PAYMENTS, DUES & EXPENSES

Track paid, unpaid and partly paid invoices in one place.

Record payments by cash, UPI, bank transfer or cheque. See pending dues clearly and follow up with customers more easily.

Record expenses, purchases and supplier-related costs to maintain a better view of your business money flow.

SMART DOCUMENT DETAILS

Set default Terms & Conditions and default Notes that automatically appear on every invoice and quotation.

HSN/SAC codes print correctly across invoice themes where applicable, helping you create cleaner and more accurate billing documents.

Your PDFs can include logo, signature, stamp, GST details where applicable, bank details, UPI, notes and terms.

REPORTS & INSIGHTS

View useful reports for sales, payments, expenses, inventory and business performance.

Understand what is paid, what is pending, what is selling and how your business is moving — without messy spreadsheets.

OFFLINE FIRST
