For a sponsor like that usually doesn’t make sense to put her offering on a 506C/Crowdfunding portal and pay an extra fee. occasionally I do see some do this anyway.

Tenant = Job of a unit or a property Products successfully integrated with QB - SmartVault or SourceLink, billing solutions, Intuit Merchant Service - specially with vacation rentals, blank check stock, industry specific websites - Would love to work with bill.com, Method Integration (which gives you a web portal, and integrates with QB) and/or QuickBase.

@Rick Bassett Does Lowes have an online portal to view receipts like Home depot does?
