The real problem
Quoted revenue does not equal usable cash.
Contractors often pay for materials and labor before the customer pays the remaining balance. A profitable-looking estimate still leaves a funding gap at the start of a job.
Estimate what portion of direct costs falls due upfront, whether the deposit covers the outlay, and what deposit percentage would cover the exposure.
Review the effect of a higher direct-cost scenario while holding the customer quote fixed. Spot an unprofitable bid before approval.
Print or save a customer-facing estimate as PDF. Internal costs, profit and business assumptions remain outside the printout.
Local browser storage, original JSON backup and CSV customer quote export. The offline application does not require customer data upload.
Planned introductory price: $19 USD once. The product includes an offline local application and instructions, not scheduling, CRM, bank feeds or payment collection.
