Independent pizza shop owners using Restoplus build the same workaround: export the transaction CSV, paste it into a spreadsheet, manually subtract the Uber Eats commission, try to remember last month's cheese price, and come up with a rough profit figure that is usually out of date before they finish it.
Most only get a real look at the numbers once a year, when the accountant reviews the books. By the time the accountant has the numbers, the decisions that could have changed the outcome have already been made - or not made.
The gap is not a Restoplus problem. Restoplus is a POS, not a profit calculator. The gap is that no tool has ever been built to sit on top of Restoplus and translate what it captures into the plain-English answers that actually change how you run the shop.
