Zency uses OCR to recognize text inside your documents, making it easier to find an old receipt, invoice, contract, or record without manually browsing through folders and images. For supported documents, Zency can also suggest information such as dates, total amounts, and tax amounts to help reduce manual data entry. TAX DOCUMENT ORGANIZATION Keep important receipts, invoices, and tax-related documents together and easier to review. Mark documents that are relevant to your tax records and keep useful information such as dates, amounts, and tax amounts organized for later review and export. Zency helps you organize your records but does not provide tax, accounting, or financial advice. REMINDERS FOR IMPORTANT DOCUMENTS Documents often contain dates you need to remember. Create reminders for bills, insurance documents, contracts, warranties, renewals, subscriptions, and other important records so they are easier to follow up on when needed. BUSINESS CARDS & CONTACTS Save business cards and contact-related documents alongside your other important records. Keep documents connected to the people and businesses they belong to instead of leaving them scattered across photos, downloads, and folders.
