Absolutely. Your privacy is our top priority. All data processing happens entirely in your browser—we never transmit, store, or see your client information, payment details, or business data. No personal information is sent to our servers except through API calls for AI document generation, which process data ephemerally without storage. We don't use cookies to track you, sell your data, or share it with third parties. Your invoices and documents remain yours and yours alone.

Yes! All our invoice templates, purchase orders, and legal documents are designed to comply with US business standards. Our invoice generator meets IRS requirements for business records, includes proper fields for EIN/SSN, and supports all US tax types including sales tax and GST. Legal documents like NDAs, contractor agreements, and lease agreements follow standard US legal formats. However, we recommend consulting with a qualified attorney for specific legal situations in your jurisdiction.

InvoiceCore Hub supports multiple invoice types: standard invoices for service-based businesses, specialized invoices for plumbing contractors, estimates/quotations for clients, credit notes for refunds or returns, debit notes for supplier adjustments, purchase orders for vendor ordering, and delivery challans for shipment tracking. All templates include fields for itemized line items, tax calculations, discounts, shipping costs, and payment terms.

Simply upload your company logo when filling out the invoice form. You can upload image files (PNG, JPG) or paste a logo URL. The logo will automatically appear on your generated PDF invoices, making them look more professional and branded. If you don't have a logo yet, you can leave this blank and add one later.

Yes! You have full control. You can set custom invoice numbers using any format you prefer (e.g., INV-001, 2024-001, etc.). All invoices include customizable dates, due dates, and payment terms. The system doesn't enforce any specific numbering scheme, allowing you to follow your own business conventions.

InvoiceCore Hub provides AI-powered generation for multiple legal document types including Non-Disclosure Agreements (NDAs), Independent Contractor Agreements, Lease Agreements, LLC Operating Agreements, Privacy Policies, Bill of Sale documents, Offer Letters, and Bill of Lading forms.
