Not plain SaaS. You tell me what you want on screen; I wire QuickBooks and your real tools to match how you sell. Keep your bookkeeper, or have me handle the books.
Fictitious company names. No password: click one and look around.

See the multi-business sample: a hub with an Operations Center plus three trade portals you can open (fictitious data, same screens we ship on this site).
Open multi-business sample →Every build starts with what you want — margin per ticket, jobs in progress, who still owes you — not a template everyone else uses. Keep your bookkeeper or bring me the books. QuickBooks stays the books; the portal is where you actually look. You get me, not a ticket queue.
Your trade and the screen you wish you had. I’ll send the closest sample or point you at a call.
