General contracting has a scheduling structure that spans months rather than hours. An estimate visit happens in week one. Material orders go out in week three. Subcontractors are committed in week four. Demolition starts in week six. At every one of these points, a cancellation or change of heart by the homeowner has a cascading effect on everything that comes after. The deposit structure for a GC business needs to protect each commitment point, not just the initial appointment.
Booking software in the traditional sense matters primarily for estimate visit scheduling. Project management software handles the rest. Understanding where each tool fits prevents the frustration of trying to use a project scheduling tool for customer acquisition and vice versa.
The estimate visit: where GC customer relationships begin
A residential remodeling estimate visit for a kitchen renovation, bathroom addition, or finished basement typically takes 60 to 90 minutes. You walk the space, take measurements, ask about priorities and budget, review any existing drawings, and develop a preliminary scope understanding. This is professional time with real value, even if the estimate itself is presented as free.
Homeowners who book a GC estimate and then are not home, or who book estimates with three GCs simultaneously and cancel the ones they are less interested in, waste that professional time at no cost to themselves. A paid estimate visit fee of $100 to $200, applied toward the project if the homeowner proceeds, is industry standard for larger remodeling projects and widely accepted by serious homeowners.
The homeowners who push back on a paid estimate visit are often homeowners who are still in the exploration phase rather than the decision phase. A homeowner who is genuinely planning a kitchen remodel in the next 6 months understands that a contractor's assessment time has value. The paid estimate filter is a professional signal that also improves the quality of your estimate calendar.
The project deposit: the most important financial protection in GC work
The initial project deposit, collected at contract signing, is the most important financial protection in general contracting. Industry standard for residential remodeling is 25 to 33 percent at signing. This deposit covers material orders placed before work begins, subcontractor commitments made based on the project schedule, and the opportunity cost of blocking your schedule for the project duration.
A homeowner who cancels a kitchen remodel after materials are ordered and a tile setter has been committed for the third week of the month has cost you real money: restocking fees, subcontractor cancellation fees, and the lost project revenue. A 25 to 33 percent deposit partially compensates for these losses and creates enough financial commitment that most homeowners communicate changes proactively rather than simply going quiet.
Progress payments tied to project milestones protect subsequent commitment points. A payment due at rough-in completion, another at drywall completion, and a final payment at project completion creates a structure where the homeowner's financial stake in the project grows alongside yours. A homeowner who has paid 60 percent of a kitchen remodel is not walking away without a serious conversation.
What GC businesses need from booking software
For estimate visit scheduling: a booking page that collects a paid estimate deposit, shows real calendar availability, and sends SMS reminders with site visit preparation instructions. This is what GrabMySlot handles well.
For full project management: Buildertrend, CoConstruct, or Procore handle scheduling, subcontractor coordination, document management, and progress billing. These are the tools built for the project management complexity of GC work. They are worth the investment once you have enough project volume to justify the cost.
For a solo GC or small shop doing 4 to 8 projects per year: a combination of GrabMySlot for estimate booking, a standard contract template for project deposits, and QuickBooks for invoicing handles the workflow without the overhead of enterprise project management software.

Setting up estimate visit booking with a deposit
Create a job type in GrabMySlot called "Project Estimate Visit" with a 90-minute block and a $150 deposit. Include preparation requirements in the job description: clear access to all areas being assessed, any existing drawings or plans available, and both decision-makers present if the project requires sign-off from multiple people. Set a 48-hour cancellation window.
Share the booking link with homeowners who inquire by phone or email. "I have Thursday afternoon open for a site visit. You can book and confirm the estimate appointment here: [link]. The deposit applies toward your project." That message converts a phone inquiry into a confirmed, deposited estimate visit without a callback loop.
GrabMySlot is free to start. You pay 3 percent only when you collect a deposit. Set up your booking page in under five minutes at grabmyslot.com.
