Finance or compliance software usually starts from one of our fixed-price packages: Validate, $3,900 in 2 weeks for one core flow or one automated process; Launch, from $8,000 in 8 weeks; or Scale, from $15,000 in 10–14 weeks for marketplaces and heavy integrations. You get the exact price and launch date in writing before any code is written.
Yes. WiseCost connects to QuickBooks Online and imports payroll from any CSV export. Other integrations are scoped and priced up front, through their APIs.
