Tax and finance apps for US and Canadian businesses
Lume Autonoma builds tax and finance apps that read your invoices and receipts, sort every expense, track US sales tax, GST/HST or PST, and remind you before each filing deadline. Your accountant or CPA reviews and signs off; the software does the legwork for businesses in the United States and Canada.

Who it is for
Owners and finance teams who spend evenings sorting receipts, businesses that collect sales tax in more than one state or province, and accountants who want clean, sorted records from their clients.
For businesses in the US and Canada
US sales tax rules differ by state, and in Canada GST/HST and PST differ by province. The app tracks the rates and categories you set up with your accountant. It does not give tax advice: every filing is reviewed and signed off by your accountant or CPA.

What it costs
Every project has a fixed price, agreed in writing after a discovery call, so there are no hourly surprises. You pay on one of our two payment plans, Elite or Normal, set out in our terms. See the payment plans.
After launch, the monthly plan is US$250 a month and covers security updates, monitoring and fixes. You can cancel it at any time.
Anything that runs in accounts in your name, such as phone lines, AI model usage or a hosting provider, is billed by that provider at its own rates.
Questions
Does the app file my taxes?
No. It prepares the figures: it scans invoices and receipts, sorts expenses, tracks sales tax, GST/HST or PST, and reminds you before each deadline. You or your accountant review and file, and the app is not tax advice.
Does it handle both US sales tax and Canadian GST/HST?
Yes. It tracks US sales tax, GST/HST and PST, with the categories and rates you and your accountant set up.
Can my accountant use it?
Yes. It produces accountant-ready exports and filing checklists, so your accountant or CPA reviews organized records instead of a box of receipts.
How much does a tax and finance app cost?
Each app has a fixed price, quoted in writing after a discovery call. After launch, the monthly plan is US$250 a month and covers security updates, monitoring and fixes.
Is our financial data safe?
It stays in accounts you own. For sensitive work we deploy private models on your own servers, so nothing is sent to a third-party AI.
