We publish ScopeBid, an iPhone and iPad estimate and invoice app for independent contractors and service businesses. Reuse pricing from past jobs, adjust labour and materials, compare estimated gross margin and markup, and create customer PDF quotes. Approved quotes can become invoices, with separately priced change orders and recorded payments. Core work is available offline without an account. The first three quotes are free; unlimited quoting and the full workflow require an optional Pro subscription. ScopeBid records payments received elsewhere; it does not process cards or move money. Estimates depend on your inputs and are not accounting or tax advice.
