From invoice to what you keep, in one place.

ReckonOS covers the money side of client work. You invoice in your own template, clients pay into your own gateway accounts, every cost is filed to a project, and each payment updates two numbers: the project’s true margin and the tax you should set aside.

Product areas

Invoicing & templates

Send invoices in 15 designed templates with your logo, in any currency, with tax worked out per client. One export format, set once for your workspace.

How invoicing & templates works

The sample invoice in the Swiss Modern Grid template, from Northbank Studio to Halden Coffee Co.

Tax Shield

ReckonOS applies VAT, GST and reverse-charge rules to each invoice and estimates the tax to set aside from every payment. Estimates, not tax advice.

How tax shield works

The Tax Reserve Vault in the sample workspace, with the rules and sources panel for United States (NY).

True margin

Log labour, contractor and software costs against each project and see its real margin while the work is still running, not after the year closes.

How true margin works

True margin for the sample Brand refresh project: revenue, labour at cost, other costs, gross profit and margin.

Client portal

Every invoice gets a private link where your client can view it in your template, download the PDF and pay through your gateways. No client login.

How client portal works

The client pay page on a phone: balance due, due date, one download button and bank transfer details.

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).

  • Payments & gateways

    Connect your own Stripe, Paystack, PayPal, Flutterwave or crypto gateway accounts. Clients pay you directly; ReckonOS never holds client money.

  • Expenses & receipts

    Photograph a receipt and ReckonOS reads the merchant, date and amount for you to check, then files the cost against a project so margins stay true.

  • Reports

    Cash-basis revenue, profit and loss, a tax summary by component, an ageing report of unpaid invoices, project P&L and a 1099-NEC export.
