What QuickBooks does well, and where it stops
QuickBooks is accounting software. It's very good at invoices, bills, payroll, tax and the reports your accountant asks for. Intuit keeps adding to it; QuickBooks Online Advanced recently added reorder points with low-stock alerts and sales orders tied to purchase orders.
What it isn't built to do is run a make-to-order shop floor. It doesn't know that a part goes through the saw, the press brake and the welder, how long each step takes, which machine is free on Thursday, or what a job really cost against what you quoted.
That's the gap most shops fill with spreadsheets. Tangle is built to fill it instead.
