Can the project be changed after delivery? — answered by Engineer Saeed Baatiah
Yes. Post-delivery changes are estimated and priced separately from the original contract, either at a fixed price for the specific change or through a monthly block of hours if changes are frequent. The monthly block is usually cheaper when you expect continuous change, because it removes the cost of reopening the project and re-understanding its state each time. And since the code is yours, you can also engage any other developer — nothing locks you in.
