Every job app can multiply an area by a rate. What decides whether you make money is whether the material cost in that number is the one your merchant actually charges you — and whether the bag count matches how thick you lay it. Both of those are yours to set, and the app builds everything else off them.

Most apps hand you one alphabetical list of a thousand products and let you scroll. PlasterFlow narrows it the way a merchant's counter does: pick the brand, then the type, then the product. Three taps instead of a search.
Two renderers on the same wall with the same product can be a pallet apart. The app doesn't pretend otherwise: coverage is a setting, in square metres per bag, and it's yours.
Set it in Business Details → coverage rates. Every take-off, every quote and every order list from then on counts bags at your rate rather than a datasheet's ideal.
Too low and you're short on the Thursday and the job stops. Too high and you've bought a pallet you're storing in the garage. It's the same number driving both the estimate and the order.
It's stored against your account and synced to your other devices, so it isn't something you re-enter per job.
The measurements you took on the visit are the same measurements that produce the materials list. Nobody re-enters anything, so nobody mistypes anything.
Not just “render”. For a named system that means the primer, the base coat, the mesh, the beads, the topcoat — in the manufacturer's build-up, at the thicknesses that system specifies. For plastering it's boards, adhesive, scrim, angle bead, bonding and finish, with a partition counted as boarded on both faces.
And it describes what it charges you for. If mesh is in the order, mesh is in the scope of works the customer reads. A materials list and a scope that disagree is how arguments start.

The order list names the actual products for the brand you picked — not a generic stand-in from a different manufacturer. You can hand it to the counter as it is.
The count is a starting point, not a rule. Bump a line up because of waste, drop one because you've got half a pallet already — the totals follow.
Switch to Build order and set quantities with − and +. The bar at the bottom keeps a running total including VAT as you go, so you know what the delivery is going to cost before you've sent it.
View / send turns it into an order split by supplier — the render house gets the render, the merchant gets the boards — and sends it on WhatsApp or email, or copies it to paste wherever you like.
Keep your suppliers' names, emails and phone numbers in Tools → Suppliers so ordering is picking one, and so what comes back gets filed against the right account.
Ticking remind me when you add materials drops it into your to-do list with a time on it — so “pick up mesh” rings your phone at 7am rather than occurring to you at 9.
What you order becomes what the job cost, so the profit so far figure is real spending and not an estimate. Jobs & money →
Because your prices live in one place rather than inside old quotes, a supplier putting 8% on a bag is a number you can actually see, instead of a margin that quietly disappears.
