Most contractors lose jobs not because their price was wrong or their work was bad — they lose because they went silent after the proposal. Here is the data on what actually closes jobs, and the exact follow-up sequence that runs automatically while you are on site.
A Harvard Business Review study tracked 100,000 companies across sales response times and found that companies who respond to leads within five minutes are 21 times more likely to convert than companies who respond after 30 minutes. For contractors, the equivalent is the walkthrough-to-proposal window. The contractor who sends a professional proposal within 5 minutes of finishing the site visit is not slightly more likely to win — they are categorically more likely to win. The homeowner is still at the property. The job is still top of mind. The competition has not called back yet. Sending fast is a strategy, not a courtesy.
This number comes from contractor sales research that tracked homeowner decision-making across 10,000 residential service jobs. The homeowner gets three estimates. They intend to compare all three and make a rational decision. In practice, 78% of the time they hire whoever follows up first in a professional way — a text or email that shows they remember the job, references the specific scope, and makes it easy to say yes. Most contractors never send a second follow-up. They send the proposal, then wait. The homeowner gets busy. Silence sets in. The job goes to the contractor who did follow up.
The follow-up sequence that closes the most jobs is not complicated. Day 1 (within 24 hours of sending the proposal): a text that confirms they received it, references the job type and address, and includes a direct link back to the proposal. Day 3: a follow-up that asks if they have questions and reiterates one key point from the scope — something specific to their job, not a generic "just checking in." Day 5: a final message that creates mild urgency without pressure — mention that scheduling is filling up for the month, or that the proposal price is held for 7 days. After Day 5, most contractors stop. Homeowners who were not ready at Day 5 rarely convert from additional cold follow-up. This system recovers the maximum number of jobs with the minimum number of touches.
Subcontractors and general contractors scaling from $100K to $1M in revenue are in the part of the growth curve where every proposal matters. At $100K you can survive on referrals and word of mouth. At $500K you need a repeatable system. At $1M you need automation. A sub bidding 20 jobs a month who recovers even 2 additional jobs per month from better follow-up — at an average job value of $25,000 — adds $600,000 in annual revenue. The math is straightforward. The limiting factor is time: a GC managing two active job sites cannot manually text 20 homeowners every three days. The system has to run without them.
WonTheJob sends Day 1, Day 3, and Day 5 SMS follow-ups automatically after a proposal is sent. Each message includes the homeowner's first name, the job type, and a direct link to their proposal portal where they can review the full scope and sign electronically. The contractor does nothing after the initial send. No scheduled reminders. No manual texts. No following up on following up. Contractors using the automated sequence report recovering 2–4 jobs per month that they would have otherwise written off as ghosted. At average contractor job values, that is $50,000–$150,000 in additional revenue per year from a feature that runs entirely in the background.
A general contractor in Phoenix was doing $400K a year when he started using WonTheJob. His proposal close rate before: 22%. He was sending proposals manually, following up once maybe twice, and moving on. After six months of automated follow-up, his close rate is 34%. That 12-point improvement on his proposal volume meant 14 additional jobs per year at an average of $35,000 each. That's $490,000 in additional contracted revenue. He did not change his pricing. He did not hire a salesperson. He changed what happened after the proposal was sent. The system handled the follow-up. He focused on running the jobs.
