Your expertise, invoiced like a firm.
For independent consultants and advisers, ReckonOS bills day rates, hourly work and monthly retainers in your own invoice design and the client’s currency, applies cross-border VAT rules such as reverse charge, and shows how much of each payment to set aside for tax before you spend it.
What ReckonOS handles for a consulting practice
-
Bill day rates and retainers
Log days or hours with the timer or a timesheet and turn billable entries into invoice lines at their rate. Monthly advisory work runs as a recurring invoice.
-
Invoice a client in another country
Bill in the client’s currency. ReckonOS applies the cross-border treatment from where you both are, such as EU reverse charge or UK outside-the-scope wording, and prints the reason on the invoice.
-
Set aside tax before you spend it
Each payment you receive is split into what to set aside and what is yours. VAT or GST inside the payment is reserved in full, plus an income-tax share at a rate you choose from 20% to 35%.
Real ReckonOS screens from a sample workspace. Northbank Studio, its clients and every figure are invented. Tax figures are estimates based on the rules for the United States as of November 2026. Check with your accountant. Sources: IRS Form 1040-ES (opens in a new tab); IRS Publication 505 (opens in a new tab). -
Look like a firm on paper
Fifteen invoice templates carry your logo, or a monogram if you have none, and the client downloads the same design as a PDF from a private link.

Consultant questions
I am a one-person consultancy. Which plan fits?
Starter: one user, one payment gateway, 50 receipt scans a month, every tax system, all 15 templates and unlimited clients and invoices. Your accountant joins on a free seat.
Can I bill by the day rather than by the hour?
Yes. Invoice lines take any quantity and unit price, so a line can be 4 days at your day rate. Timer entries are in hours if you track time that way.
What is the Tax Reserve Vault?
The Tax Reserve Vault is a calculation, not a bank account: ReckonOS works out how much of each payment you have received to set aside for tax, and shows it next to the profit you can spend. The money stays in your own account.
Does ReckonOS file my tax return?
No. It estimates what to set aside and shows the rules and their sources. Check the numbers with your accountant before you file.
