Ship the build. Know what it earned.
For software and web development studios, ReckonOS bills fixed-price builds in milestones and support as retainers, records developer hours at their cost rate and contractor invoices against each project, and shows the true margin while the build runs. Clients pay into your own Stripe, PayPal or Paystack account.
The billing work a dev studio does every month
-
Bill a build in milestones
Split a project into phases. Each milestone stays locked until the one before it is paid, then becomes an invoice in one click, in the client’s currency.
-
Run support and maintenance as a retainer
Set a recurring invoice once and ReckonOS issues the next one on schedule, with reminders 3 days before the due date, on the day, then 3, 7 and 14 days after.
-
Know if a fixed-price build made money
Developer hours at each person’s cost rate, contractor invoices and the hosting or tools you file to the project come off what you billed. The margin shows while the build is still running.
Real ReckonOS screens from a sample workspace. Northbank Studio, its clients and every figure are invented. -
Pay contractors without losing the paperwork
Record contractor costs against the project, and for US studios collect W-9 details (tax IDs encrypted at rest) and export a 1099-NEC CSV at year end.
-
Invoice clients abroad correctly
VAT, GST and reverse charge are worked out from where you and the client are, with the reason printed on the invoice, so a UK studio billing a German company gets the wording right.
What ReckonOS does not do
- It does not import time from Git hosting or issue trackers; time is logged in ReckonOS.
- It is not a double-entry ledger; your accountant gets reports and exports.

Dev studio questions
Can ReckonOS bill a fixed-price build in phases?
Yes. Add milestones to the project; each one stays locked until the previous phase is paid, then invoices in one click. Time-and-materials work can be billed from timer entries at their rate instead.
How do we see whether a project was profitable?
Cost of Execution (CoE) is everything it costs you to deliver a project: the hours your team spends valued at their labour rate, contractor fees, and the software and other expenses you file against that project. True margin is what you billed minus the Cost of Execution.
Do contractors count as users?
No. Contractors are records you pay, not people who sign in. Users are the teammates who log in: Pro includes up to 10, Studio up to 50, and accountant seats are free.
Does ReckonOS connect to our code repositories or issue tracker?
No. Time is logged with the ReckonOS timer or on a timesheet. There is no import from Git hosting or issue trackers.
