Finish multiplier — broom × 1.0, exposed × 1.4, polished × 1.8
Why tradies switch
Faster quotes, the same maths every time.
Reo + mesh you didn't forget
Every concreter has a story about a quote that didn't include the mesh. The engine bakes it into the line items so the customer sees it itemised and you don't get stuck on margin.
Pump truck vs barrow, scored
Site access prompts (truck reach, distance from pour, slope) feed the engine's labour multiplier. No manual rule-of-thumb adjustment.
Finish multipliers built in
Broom finish, exposed aggregate, polished — three different jobs, three different prices. Tick a box, the m³ rate adjusts.
Under the bonnet
How the engine handles the edge cases
Spillage isn't a fixed 5%. It scales with pump distance and pour complexity. A straight pump-truck pour onto a clean rectangle wastes maybe 3%. A wheelbarrow line on a sloped block with a curved kerb can lose 8%. The engine asks two access questions in the configurator and dials the spillage buffer between 3% and 8% based on the answers, so your supplier delivery quantity matches what actually goes down.
Formwork linear metres aren't just the perimeter. The engine adds 15% for offcuts on timber form, 5% for steel because steel cuts cleaner. If you tick 'reusable steel' in onboarding, the formwork line moves from per-metre cost to per-metre hire rate. Most concreters mix the two, so you can override per quote.
Pump truck vs wheelbarrow line isn't a UI toggle: the engine calculates both and surfaces the cheaper one with a 'why this picked' note. For a 6m³ pour 25m from the kerb, the pump truck wins (faster, less labour) even though the callout fee is $300. For a 2m³ pour right at the kerb, the wheelbarrow line wins because the pump callout dominates. Saves a real conversation with the customer about why you're charging for a truck on a small job.
Concreting · FAQ
Trade-specific questions.
The questions concreting tradies actually ask. Want to see how it works on a real job?
Does it handle driveways with a kerb?
Yes. Kerb is a separate linear-metre line item with its own rate. Driveway m³ plus kerb linear metres on the same quote, both rebased to your supplier and labour rates.
Can I quote a slab on a sloped block?
Site access is one of the onboarding answers; it bumps labour by the right percentage. For severe slopes, override the labour line per quote. The engine respects per-quote overrides.
What about mesh vs reo bar?
Both. Pick mesh for small slabs (driveways, paths, patios). Engine calculates m² with 200mm overlap. Pick reo bar for structural slabs. Engine prompts for spacing and gauge, then calculates linear metres.
What MPa does the engine default to?
20MPa for paths and slabs under 100mm. 25MPa for driveways. 32MPa for structural footings or anywhere over 150mm. Override any time. The price per m³ shifts with MPa because the supplier rate is loaded for each grade in your onboarding.
Does it know about pump truck reach + minimum charges?
Pump truck is a separate line item with a callout fee plus per-m³ rate. The engine prompts for distance from the kerb to the pour location. Over 30m and it suggests a long-reach pump (different rate). Most suppliers also have a 4m³ minimum charge; the engine flags it if your job's below that.
What about exposed aggregate and stencil finishes?
Finish is a multiplier on the labour line, not an add-on. Broom is the baseline (1.0x). Stencil is 1.3x. Exposed aggregate is 1.4x (extra rinse, longer hold). Polished is 1.8x (multi-pass grinding). Pick the finish, the engine adjusts labour without you doing the percentage in your head.
Can I quote a pour with two finishes (e.g. broom driveway + exposed border)?
Yes. Split the pour into two line items, each with its own m² and finish. The engine uses one supplier rate for the m³ (it's all the same pour) but splits the labour at the right multiplier per area. Customer sees two clearly labelled finishes on the PDF.
