Invoices – 8 Free CSS, Bootstrap & Tailwind Sets
Invoices is a pack of eight sets of HTML invoice templates, designed and maintained in-house by uiCookies. Every set comes in three versions that look the same: plain HTML and CSS, Bootstrap 5.3 built on its own cards, tables, badges, buttons, form controls and dark colour mode, and Tailwind CSS 4. The sets cover classic printable invoices for A4 and US Letter, modern minimal invoices with a brand colour band, an invoice builder with editable line items and currency formatting, inline-styled invoice emails, a billing dashboard with status filters, till receipts and payment confirmations, a dark set that prints light, and a container-query invoice built on subgrid.
A good invoice answers three questions at a glance: how much, by when, and how to pay. The amount due and the due date sit near the top, the line items are a real table with column headers, item names as row headers and totals in the table footer, and every figure uses tabular numbers so the columns line up. Totals are rounded per line in the currency's smallest unit so they always add up, and the currency is named. An invoice will be printed and saved as PDF, so it needs print styles: page margins, a header row that repeats on every page, rows that never split, no buttons or dark backgrounds on paper. Status labels such as Paid or Overdue need a word and an icon, not just a colour, and an invoice sent by email needs inline styles and layout tables, because email clients ignore most of a stylesheet.
