Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Sleek Bill is invoicing and billing software for freelancers, small businesses, accountants, retailers, manufacturers, and service providers. It covers invoices, quotations, proforma invoices, delivery notes, credit notes, GST and composition-scheme support, inventory tracking, reports, cloud-stored data, and offline desktop billing. The browser-based product runs on the web, while desktop software supports Windows and macOS. Recurring invoices and payment reminders are also included among its core capabilities.
The pricing structure starts with Free Forever at $0 per month, including 10 documents per month, GST compliance, basic reports, basic GSTR1 and GSTR3B export, customizable labels, and limited support. Premium Business Plan costs $69 per year and adds unlimited documents, unbranded documents, multiple paper templates, inventory management, credit and debit notes, and email support. Multi User Plan costs $99 per year, adds up to 5 users, VAT and custom tax options, expenses, data security, auto backup, and priority support. The catalog also includes Premium LIFETIME at $299 one-time, Premium Yearly at $99 per year, Premium + Inventory LIFETIME at $399 one-time, and Premium + Inventory Yearly at $199 per year. The inventory-focused plans add vendors, purchase orders, bills, inventory reports, POS, GSTR reports, and thermal-print support.
Sleek Bill suits businesses that want a low-cost invoicing system with Indian GST workflows and a desktop mode for offline billing. Its breadth is useful for businesses that also need inventory, reports, recurring billing, reminders, or POS-related features. The free tier provides a straightforward entry point, while annual and lifetime options support different purchasing preferences. However, businesses prioritizing integrations or online payment support should consider alternatives, since those capabilities are not listed for the standard product plans. Choose Sleek Bill for focused billing and GST administration; look elsewhere for a broader connected payment ecosystem.
