Scan-to-Budget with RENDR + JobTread: Frequently Asked Questions

This FAQ explains how the RENDR × JobTread workflow works, what parameters a scan gives you, how quantity formulas use them, and how to get our free Field Guide and Quantity Formula Library.

Turn a RENDR scan into a JobTread budget — automatically.


What is the RENDR + JobTread integration, in one sentence?

You scan a space once with RENDR, and the measurements sync into JobTread as parameters that your quantity formulas use to build the estimate — so your budget quantities calculate themselves instead of being keyed in by hand.

How does it actually work?

There are three moving parts:

  1. You scan a space in RENDR and get a floor plan. RENDR calculates parameters from the scan (floor area, wall area, cabinet runs, fixture counts, and more).

  2. Those parameters sync into your JobTread job through the integration.

  3. Quantity formulas you've built into your JobTread cost items read those parameters and calculate the quantities on your budget.

The short version: RENDR captures what exists, and JobTread applies what you already know.


What is a quantity formula?

It's a small formula attached to a cost item's quantity in JobTread that calculates "how much" from a RENDR parameter instead of you typing a number. Build it once, and every future scan fills it in.


What are some example formulas?

These use the whole-plan parameter (for example {Area} is the entire scanned floor). To scope a formula to one room, add a room prefix — {Kitchen: Area}, {Bath 1: Area}. Parameter matching is not case-sensitive, but the words have to match.

Flooring material (SF):        {Area} * 1.10 Interior paint (gallons):      ceil({Paintable Surface Area} / 350 * 2) Drywall board (sheets):        ceil(({Wall Surface Area} + {Ceiling Surface Area}) / 32 * 1.10) Baseboard (LF):                {Perimeter} - {Number Of Doors} * 3 Cabinet install (LF):          {Base Cabinets} + {Wall Cabinets} Recessed lights (EA):          round({Area} / 30) Faucets / vanity lights (EA):  {Number Of Sinks}

The 1.10 is a 10% waste factor, 350 is paint coverage per gallon, and 32 is the square feet in a sheet of drywall — all numbers you can tune to your business.


Can you show the production-rate idea?

Say demolishing 1,000 square feet of tile takes about 32 labor hours. That's a production rate of 0.032 hours per square foot. Instead of guessing every time, you build it into JobTread:

Tile demo labor (hours):       max({Area} * 0.032, 4)

Now a 2,000 SF job calculates 64 hours automatically, and a small 100 SF job is protected by the 4-hour minimum (for setup, mobilization, protection, and cleanup). If you'd rather estimate in 8-hour man-days instead of hours:

Tile demo labor (man-days):    max(ceil({Area} * 0.032 / 8), 1)

The production rate scales the work; the minimum protects the estimate.


What RENDR parameters are in a scan?

These are the parameters we use to build our Quantity Formula Libraries. One parameter often drives several line items — the classic example is a sink count, which tells you the faucets and the vanity lights and the mirrors.

Areas and surfaces (square feet):

  • {Area} — the floor area of the space. Drives flooring, floor demo, floor protection, final cleanup, and area-based labor like tile demo.

  • {Wall Surface Area} — total wall face area. Drives drywall, wall insulation, and wall demo.

  • {Ceiling Surface Area} — the ceiling area. Drives ceiling drywall and paint; often added to wall area for total board.

  • {Paintable Surface Area} — walls plus ceiling, net of openings. Drives paint and paint prep.

  • {Countertops} — countertop area (RENDR provides counters as area, not linear feet). Drives countertop material and fabrication.

  • {Backsplash Area} — backsplash area. Drives backsplash tile and install.

Lengths (linear feet):

  • {Perimeter} — the wall run around the room. Drives baseboard, crown, shoe/quarter-round, and receptacle spacing.

  • {Base Cabinets} — linear feet of base cabinets. Drives base cabinet supply and install.

  • {Wall Cabinets} — linear feet of wall cabinets. Drives wall cabinet supply/install and under-cabinet lighting.

  • {Median Wall Height} — the typical wall height, handy for converting a wall run to an area or sanity-checking a scan.

Counts (each) — one count, many line items:

  • {Number Of Sinks} — in a bathroom this can drive the faucet, the vanity light, the mirror (or medicine cabinet), the GFCI receptacle, and the towel bar and ring — typically one of each per sink.

  • {Number Of Toilets} — drives the toilet, its rough-in, and the TP holder.

  • {Number Of Bathtubs} — drives the tub, the tub/shower valve, and (with a surround constant) the tub-surround backer and tile.

  • {Number Of Doors} — drives door casing and install, and the deduction in a baseboard formula, since each opening removes a few feet of base.

  • {Number Of Windows} — drives window trim/casing.

  • {Number Of Openings} — cased openings and passages; drives headers and opening trim.

Flooring regions (square feet) — when you draw a dedicated flooring area in RENDR:

  • {Flooring Gross Area} — the full drawn region before deductions.

  • {Flooring Excluded Area} — areas carved out, like an island or cabinet footprints.

  • {Flooring Net Area} — gross minus excluded; the number to price flooring against.

You can use any parameter for the whole scanned plan ({Area}) or scope it to a room with a prefix ({Kitchen: Area}). You can even mix both in one estimate — for example, paint and floor the whole floor with {Area} while pricing only the kitchen's cabinets with {Kitchen: Base Cabinets}.


Why do room names matter so much?

Your formulas look for parameters by room. If the room names in your scan match the names your JobTread templates expect, the parameters map automatically. If they don't match, the formula can't find its value. Consistent naming is what makes a template reusable on every job — and because you control room names in RENDR, you're in control of how everything maps.


What is RENDR Flex, and how does it fit in?

Flex lets you fully edit your plan after scanning — correct measurements for accuracy, adjust walls, doors, windows, and openings, rename and organize rooms, or create entirely new layouts for a renovated space. Since your room names drive your room-based parameters, naming rooms to match your JobTread templates is what makes everything connect.


How long does the sync take?

RENDR calculates parameters in real time as you scan, and they're available through our API. Sync the space into your JobTread job, apply your template (JobTread calls it a Cost Group), and the estimate builds itself from the parameters.


Does this replace the estimator?

No — it removes the manual takeoff, not the judgment. You still review the project-specific scope, adjust for unusual conditions, and approve the final estimate. The goal is to reduce the work to reviewing, tweaking, and double-checking, so estimating no longer depends on one person doing every takeoff by hand.


Do I need both RENDR and JobTread?

Yes. JobTread holds your estimating system — unit costs, assemblies, production rates, quantity formulas, and minimums. RENDR supplies the project quantities that feed it. They work together.


Do I have to build all of this from scratch?

No. Our Field Guide and Quantity Formula Library give you ready-made formulas and a proven setup so you're not starting from a blank page.


How do I get the free Field Guide and Quantity Formula Library?

Both are free for any JobTread customer who attends one of our workshops. Attend a workshop, and we'll send you the Field Guide and the Quantity Formula Library at no charge.


When are the workshops?

Workshops run every other week from September through the end of 2026, with more to be scheduled (TBD).


I already attended a workshop — how do I get the resources?

Reach out to our team and ask for the Field Guide and Quantity Formula Library, and we'll get them to you.


Where do I go with more questions?
