Built for general contractors who run multiple trades.
Suparate is a general contractor estimating app for sub bids, allowances, owner selections, change orders, and milestone billing. It gives GC estimating software that keeps scope, pricing, signatures, and payments organized across every trade on the job.
Sound familiar?
Every bid depends on someone else's number
Plumbing, electrical, HVAC, drywall, tile, flooring, cabinets, and paint all feed the final proposal. When sub bids live in texts and emails, one missed number can throw off the whole project.
Allowances create client confusion
Cabinets, fixtures, tile, appliances, doors, hardware, and finishes can move thousands of dollars. If allowances are vague, the client sees every overage as your problem.
Change orders get handled too casually
A verbal yes during a remodel feels fine until the final invoice. GCs need signed approvals for added scope before the sub starts the work.
Here's how Suparate fits your workflow
Build estimates around phases and trades
Create a clear project scope from demolition through final punch. Suparate helps organize sub bids, your own labor, allowances, overhead, profit, and exclusions in one estimate.
- Phase-based scopes for remodels, additions, and repairs
- Separate lines for subs, allowances, labor, O&P, and permits
- Photos and notes tied to each project record
- Clean client-facing proposals from field notes
Get signatures before work expands
Turn estimates and change orders into documents clients can approve from their phone. Suparate keeps signed approvals with the job so every added item has a paper trail.
- Original proposals signed digitally
- Change orders for scope additions and allowance overages
- Approval history stored with the project
- Client-readable scope instead of messy back-and-forth
Bill by milestone
GC cash flow depends on billing at the right time. Suparate lets you request deposits, invoice milestones, and track what has been paid across active jobs.
- Deposit requests at contract signing
- Milestone invoices for demo, rough-in, finishes, and completion
- Open balances visible by project
- Payment history tied to scope and approvals
