For general contractors of every kind

One platform built for how any contractor actually runs the work.

Most construction software is a one-size-fits-all tool you bend to fit your trade, or a stack of six systems that don't talk to each other. This is one connected platform that runs the whole business, from the first estimate to the final closeout. Whether you build hospitals, warehouses, custom homes, or all three, it fits the way your teams already work, and it configures to your rules.

Contracting Software Services, or CSS for short, built by the people who run the jobs.

Who it's for

Built for contractors done duct-taping their business together.

If you run real projects and real money on a pile of tools that don't talk to each other, this was built for you and the way you actually work.

This is you if
  • You build commercial, industrial, residential, or some mix of all three.
  • Your estimate, your books, and your field never quite agree.
  • You pay for six tools and still re-key numbers between them.
  • You care about your margin and knowing who did what, when.
  • You're ready to run the whole company on one system.
The problem

Your software stack is fighting your business.

Estimating in one tool. Accounting in another. Field reports, scheduling, payroll, safety, and closeout scattered across five more. Every handoff is a re-key, every number lives in three places, and nothing knows what your actual job requires.

โ›“๏ธ

Disconnected data

The estimate never reaches job cost. Field data lands a week late. Your books and your projects disagree, and you find out at month-end.

๐Ÿงฉ

Generic where you need specific

One-size-fits-all tools treat a hospital wing, a warehouse, and a custom home the same. The compliance, the selections, the draws, and the closeout that each one needs end up in spreadsheets on the side.

๐Ÿ’ธ

Paying more for less

Six subscriptions and six logins, plus the integrations between them to keep alive. The per-seat total often runs higher than one platform that does all of it.

The platform

One system, from the first estimate to the final lien release.

Everything a contractor does, on a single ledger. Data flows on its own. An approved change order updates job cost, the GL, and the forecast, and nobody re-types a number.

Estimating & takeoffโ†’ Buyout & contractsโ†’ Field & daily logsโ†’ RFIs / submittals / COsโ†’ Job cost & WIPโ†’ Payrollโ†’ GLโ†’ AIA billing & closeout

Double-entry books, period-close (locking a month so the numbers can't shift after you report them), and job-cost tie-out (every dollar on a job matching the books) are part of the core, the way real accounting has to be.

The difference

Vertical-native, down to the closeout.

The platform ships knowing what each kind of project requires, and it won't let a project close until the work that matters is signed off.

  • Commercial: office and retail TI, restaurants and hotels, banks and schools, plus the regulated depth of healthcare, data centers, and cleanrooms.
  • Industrial: distribution and warehouse, manufacturing, tilt-up and PEMB shells, and cold storage, from the slab to startup.
  • Residential: selections, allowances, draw schedules, and homeowner warranty across custom homes, multi-family, and mixed-use.
Real enforcement

Compliance that's wired to closeout

These aren't checklists you can wave through. A project's commissioning gate blocks closeout until the vertical-specific sign-offs are complete, and safety-critical RFIs escalate faster on their own. The rules that keep you out of trouble live in the software your team already works in.

What's inside

Every part of the job, in one place.

Not a thin layer bolted over your real tools. Each of these is a full, capable module, built in and connected to all the others.

๐Ÿ—‚๏ธ

Project management

Schedules, RFIs, submittals, change orders, and punch, all tied to cost and closeout so nothing slips through the cracks.

๐Ÿ“

Estimating & precon

Assembly-based estimating on real, localized cost data, with bid leveling and win-probability, sharpening every time you win work.

๐Ÿ“‹

Field & daily logs

Daily reports, photos, crews, weather, and deficiencies from the field, flowing straight into cost and schedule.

๐ŸงŠ

BIM & design

Model coordination, clash detection, and design and drawing management, wired to the field instead of stranded in a silo.

๐Ÿ›ก๏ธ

Safety & compliance

OSHA logs, CAPA, and inspections, plus the vertical gates that block closeout until the sign-offs that matter are done.

๐Ÿšš

Equipment & fleet

Owned equipment and vehicles, reservations, utilization, and maintenance, each carrying its real cost onto the job automatically.

๐Ÿ“Š

Job-cost accounting

A true general ledger of record: WIP, bank rec, AIA billing, and job-cost tie-out where every dollar matches the books to the penny.

๐Ÿ‘ท

Workforce & time

Time to job cost to payroll in one continuous path. Certified-payroll-aware, multi-state, with onboarding and roles built in.

๐Ÿ“

Docs & plan rooms

Drawings, submittals, and plan rooms with version control and real markup, so everyone works from one source of truth.

๐Ÿ“ˆ

Analytics & BI

Live dashboards and forecasts computed from your own data, never a hardcoded number dressed up as intelligence.

๐Ÿงฒ

CRM

Leads, bids, pipeline, and client history in the same system you build in, so a prospect becomes a project without re-entering a thing.

Why it's better

What changes when it all lives under one roof.

One system does more than tidy things up. It changes how much of every job you actually take home.

๐Ÿ“ˆ

More profit you keep

When the estimate, the costs, and the billing all live together, you catch overruns early and bill for everything you actually earned. Less money leaks out along the way.

๐Ÿ”Ž

Accountability you can see

Every action is logged with who did it and when. When a number looks wrong, you trace it back to the source in seconds instead of guessing.

โœ…

Fewer human errors

Nobody re-types numbers from one app into another, so the small typos that quietly cost real money never get the chance to happen.

๐ŸŽฏ

Pricing smarter than you'll find anywhere

The system tracks what things actually cost you, in the markets you build in, and learns from every bid and every won job. Over time it knows your real numbers better than any generic cost book or competitor's tool ever could.

๐Ÿงฒ

A CRM built in

A CRM is the tool that keeps your sales pipeline and client history in one place. Here it lives in the same system you build in, so a prospect becomes a project without anyone re-entering a thing.

๐Ÿšš

Equipment and fleet

Know where your gear and trucks are, what each one is costing a job, and when they are due for service, without a separate spreadsheet.

๐Ÿ 

Everything under one roof

Estimate to closeout in one place. No tool-hopping, no exporting, and no wondering which app a number was in.

๐Ÿงพ

One login, one bill

One price for the whole platform. No per-seat surprises, no paid add-ons for the features you need, and no fee just to connect the pieces.

The client portal

Your clients get their own front door.

Every owner, developer, and landlord logs into one portal that shows every project you are running for them. When they have three jobs with you, they see all three in one place, updated live from the same system your team works in.

No exporting reports, no PDFs flying around by email, and no "can you resend that one." There is a clean wall between what the client sees and the internal numbers you keep to yourself.

What your client sees
  • All of their projects in one view.
  • Live billing and pay applications.
  • Change orders to review and sign off.
  • Documents, drawings, and job photos.
  • Schedule and progress, kept current on its own.
Why it's built right

Made by operators, on one ledger, for real work.

The system grew up inside a working general contractor, solving the exact problems that fragment every contractor's day. It was proven on live projects long before it was offered to anyone else, and it configures to whatever kind of building you do.

  • Every number on a screen is computed live from your own data.
  • Multi-market by design. Run one office or offices in every US metro on the same standard process.
  • Configurable to your rules and your workflows, and it stays that way as you grow.
