Ship the build. Send the bill.
Whether you’re an hourly contractor, a fixed-fee shop, or running a SaaS retainer, AllSquare keeps every invoice clean — in any currency, with branded PDFs.

Software contractors lose disproportionate time to invoicing because the standard tools don’t fit how dev work happens: irregular hour blocks across time zones, milestone-based fixed-fee work, GBP/USD/EUR mix, and a retainer or two on the side. AllSquare collapses it. Hourly clients get clean weekly or fortnightly invoices with hours and rates per day; fixed-fee projects run on PDF estimates that convert to invoices on sign-off; SaaS retainers run from saved client scope, built each month in a couple of taps. Multi-currency with 50+ currencies means a US client invoice goes out in USD, a Berlin agency in EUR, with the right tax preset applied.
