Simple accounting software for US small businesses.
Send invoices, track expenses, manage your books, and understand your finances, without the steep learning curve or the per-seat billing. Free forever for solo users.
Flexible tax configuration for every US state
Sales tax rates vary by state. Configure your default rate or set a custom rate per item. Apply tax to invoices automatically or manually, whichever fits your setup.
The problems we solve
You're paying per user and the bill keeps growing as your team does, even though the features haven't changed.
Every team member is included in one flat plan price. Add users freely. No surprise charges at month end.
You invoice clients in multiple currencies but your books only work in USD.
Multi-currency is built in on every plan. Invoice in any currency, reconcile everything in USD.
Your accounting software is complicated enough that you avoid using it, which means your books are always behind.
Nastrum Books is built for business owners, not accountants. Clean flows, plain language, no jargon.
You need to give your CPA read access but they keep having to ask you to pull reports.
Add your CPA as a Viewer or Accountant. They can run any report themselves without touching anything else.
Expense receipts end up in a pile and you spend a weekend before tax season sorting through them.
Log expenses on the go and attach your receipt photo right away. Categories, tags, and search make it instant.
Everything a US small business needs to run clean books.
