Inbound lead capture
Sarah Whitfield — referred by their architect, David Kim, AIA — fills out the "Start a project" form on cornerstonebuilds.com. Interface365 captures the lead with full source attribution to the architect referral. The form gathers project type, scope, timing, and budget envelope so the estimator can show up to the site visit prepared.
Source ("Architect referral") is configured under Settings → Sources, so attribution is automatic — and the architect is tagged on the lead immediately so reciprocity tracking starts on Day 1. Leads land round-robin on whichever PM is on intake duty.Qualification call & lead enrichment
Marcus calls Sarah within two hours, qualifies the project, and enriches the lead record with custom fields. The lead status flows New → Contacted → Qualified.
Lead conversion — one click, three entities
With the lead qualified, Marcus clicks Convert. Interface365 creates a Contact + Source organization + Deal all linked, and links them together.
Deal enrichment — decision team, custom fields, tags
Residential construction always has a decision team — both homeowners (joint signers on contracts), the architect (design authority), and often an interior designer or structural engineer. Marcus adds Jonathan and David Kim to the deal with explicit roles.
Expected contract sign: Apr 5, 2026 (31 days)
Site visit, notes & files — the full project context
Over the next two weeks, Marcus and Rachel log every interaction. The site visit, photos, scope notes, sub bid solicitations, architect drawings, and internal margin commentary all live on the deal record — nothing in side-channel emails or random Drive folders.
Referrer for reciprocity tracking — 6th project this year from his firm, total trade volume ~$3.2M.Tasks & follow-ups — never let a thread drop
Tasks attach to the deal with priority, due dates, and assignees. Polymorphic — they can also attach to contacts, companies, or projects.
Pipeline progression & stagnant alerts
As the deal advances, Marcus drags it through stages. If activity drops for 7+ days post-estimate (or 14+ days mid-bid), Interface365 flags it as stagnant and surfaces it on the dashboard. In construction the cost of a forgotten estimate isn't lost time — it's a lost project.
Pricebook — labour rates, assemblies, allowances
Cornerstone's pricebook — labour rates by trade, common assemblies (kitchen demo, foundation pour, framing per sq-ft), material categories with grade tiers, and allowances. Lifecycle states (Active / Draft / Retired) keep last quarter's lumber prices off a new estimate.
Estimate — line items by trade, allowances, snapshot pricing
Rachel assembles the formal estimate pulling line items + sub bids + allowances. Pricing is snapshotted at the moment of creation — Q3 lumber pricing changes won't retroactively touch the Whitfield's number.

Estimate lifecycle — value engineering saves the deal
The estimate came in $130K over budget. Most builders lose this deal here. Cornerstone runs a structured value-engineering conversation — three trim tiers walked through line-by-line — and lands a $720K signed contract. This is the construction conversation.

Contract signed + first draw captured triggers the deal to move to Closed Won. Probability flips to 100%. Estimator commission unlocks. Forecast updates. Construction is just beginning — but the bid pipeline's job is done. The active project moves to the project pipeline (Step 13).
Webhooks fire — Slack, QuickBooks, procurement
The instant the deal flips to Won, Interface365 fires deal.won webhooks to every subscribed endpoint. Slack celebrates. QuickBooks creates the project + first invoice. Procurement starts the long-lead-item order list (windows + appliances).
// POST https://hooks.zapier.com/... // X-I365-Signature: sha256=... { "event": "deal.won", "timestamp": "2026-04-04T16:20:18Z", "data": { "deal_id": "d_w42h7r9", "name": "Whitfield — Kitchen + Addition", "contract_value": 720000, "original_estimate": 850000, "first_draw_captured": 36000, "estimator_commission": 10800, "job_number": "WHF-2026-014", "currency": "USD", "source_organization": "Kim & Park Architects", "contact": "Sarah & Jonathan Whitfield", "owner": "Marcus Davis", "construction_start": "2026-05-05", "target_completion": "2026-09-15", "closed_at": "2026-04-04T16:20:18Z" } }
Marcus Davis just locked Whitfield — Kitchen + Addition at $720,000 ($36K first draw captured).
Estimator: Rachel Ochoa · Estimator commission: $10,800 · Construction start: May 5 · Target substantial: Sep 15.
VE saved $130K from the $850K original — full margin held. Procurement task auto-fired for windows + appliance long-leads.
X-I365-Signature: sha256=... header so receivers can verify authenticity. Failed deliveries auto-retry with exponential backoff. The Settings → Webhooks → Delivery logs page shows every fire with status code, response, and retry count.On the job + the change-order conversation
Construction deals don't end at "Won" — that's where they really begin. The active project lives in its own pipeline (foundation → framing → mechanicals → finishes → punch). Auto-tasks fire on each draw milestone. And mid-build, the inevitable conversation: "While we're at it, can we also...?" Change orders are where construction margin really lives.
Jun 16, week 7 of the build. Sarah and Jonathan walk the site for their weekly Friday update. Mid-tour, looking at the framed addition: "While the walls are open, can we also (a) upgrade the windows from Pella mid-range to Marvin Signature, and (b) add a small powder room off the mudroom? We didn't realise how much we'd use the back entrance." Tom escalates to Marcus same-day; Rachel writes CO-2026-014-01: windows upgrade +$8,400, add powder room (rough plumbing already framed-adjacent, sub re-bid 24h) +$19,800. Total: +$28,200.
Marcus presents the CO same week with a clean line-item breakdown + revised draw schedule. Both Whitfields sign on Jun 19. $14,100 (50% of CO) captured immediately as supplemental draw. Project value: $720,000 → $748,200. Substantial-completion target slips by ~6 days (Sep 21 vs Sep 15) — Sarah confirms still well clear of Thanksgiving. Tagged ● Billable change order.
Without the change-order workflow + project record: this would have been a verbal "yeah we can do that" that the field super agrees to, the homeowner forgets, the bill arrives 3 months later, and now it's a fight. Instead: scope priced in 24h, signed in writing in 3 days, supplemental draw captured, schedule reset transparently. Change orders are typically the highest-margin work on a project — properly captured, they often add 5-10% to top-line revenue at higher-than-base margins.
Dashboard view — Friday morning, week 7
It's Friday morning, week 7 of the Whitfield build. Cornerstone has 4 active builds, $3.2M in active project value, and 14 deals in the bid pipeline. The Whitfield CO + draw lands on the same dashboard as everyone else's work.
What Cornerstone set up before any of this worked
Rewind a few hours from "Day 1." Every screen you just walked through — the source dropdown on the contact form, the decision-team roles, the 8-stage residential sales pipeline, the 7-phase project pipeline, the pricebook, the change-order template — was configured once by Cornerstone's office manager in Settings. Then it reused itself through every project that followed.
