Abacus — Free Accounting & Invoicing SaaS Website Template

Abacus is a B2B accounting and invoicing template built around a CSS-and-Chart.js dashboard mock that makes the product feel real above the fold — no image editing required. It reads as a serious finance tool for small businesses (not a consumer banking app): cobalt-blue and marigold on warm-oat paper, a tabbed product tour, and a working monthly/annual pricing switch, all in plain Bootstrap 5 and vanilla JavaScript with zero jQuery.

  • Integrations grid plus a benefits column for showcasing your payment, payroll, and banking connections
  • Six-card feature grid, testimonial cards with real avatars, and a six-item FAQ using native details/summary

  • Hand-drawn inline SVG icons throughout (no icon fonts, CSP-safe) with JetBrains Mono figures for a real ledger feel

How to use it

Download the ZIP, unzip it, and open index.html — there is no build step and no dependencies to install. Replace the demo text and images with your own, point any forms at your backend or a form service, and deploy the folder to any static host. Colours, fonts, and spacing live in css/style.css; the interactions are in js/main.js. Bootstrap 5 is bundled locally, so it works offline and on strict-CSP hosts.

FAQ

Is Abacus really free to try?

Yes. Every plan starts with a full 30-day trial with all features unlocked, no credit card and no sales call. If you love it, pick a plan; if not, your data exports cleanly and nothing is charged.

Can I import from spreadsheets or another tool?

Bring your history in minutes. Abacus imports CSV files from spreadsheets and offers guided migrations from QuickBooks, Xero, and Wave, including opening balances, contacts, and chart of accounts.

How secure is my financial data?

Everything is encrypted in transit and at rest with 256-bit AES, hosted in SOC 2 Type II certified data centres. Bank connections are read-only and revocable, and we never store your banking credentials.

Does it handle sales tax and VAT?

It does. Set your rates once and Abacus calculates sales tax, GST, and VAT on every line, tracks what you owe, and produces filing-ready quarterly summaries for your accountant.
