  • Change orders agreed over SMS that never get billed.
  • Materials bought without tracking — margin disappears with no audit trail.

The 4 tools you use every day.

−31%

sub-to-sub coordination time

Project Mode + live Budget vs Actual

The job lives in 6 places: WhatsApp, Excel, Drive, email, foreman's calendar, your head. Mid-kitchen remodel ($84K), on budget? No idea — unprocessed receipts, unentered sub bills. Find out at close you lost $7K margin.

Each project = one page with sub-tabs: Overview, Billing, Financials, Time, Photos, Tasks, Documents, Daily Reports, Equipment, Materials, COs, Permits, RFIs, Safety, Subs, Analytics. Live Budget vs Actual with stoplight. EVM: SPI, CPI, EAC forecast. Every expense (AI receipt scanner), time-log, sub bill hits margin instantly.

  • Phases with dependencies (plumbing before drywall, drywall before paint)
  • Sub assigned per phase with separate contract value
  • Per-phase progress photo + visual % completion
  • Simplified Gantt for the customer to read
  • Auto alert when a phase falls behind
Parks' kitchen remodel, $84K, 6 weeks. Olynx: 8 phases, 5 subs assigned. Plumber finishes Wednesday — Olynx alerts drywaller to start Thursday. Mrs. Park opens Client Hub, sees "Phase 4 of 8 — 62% complete".

+22%

revenue recovered in COs

Change orders + sub COIs signed

Mid-remodel customer: "while you're at it, do the bar". Agree to $3K by WhatsApp. At close you claim, customer says "I never authorized that". Lose $3K. And your plumbing sub has no current COI — monster liability if something happens.

Olynx generates change order PDFs with description + cost + timeline impact + photo. Customer signs from phone with audit trail (IP + timestamp + user agent). Auto-adds to contract value + rebalances pay schedule. For subs: public HMAC signing room where they sign, upload ID, upload COI with expiration tracker — Olynx alerts before expiry.

  • Change order template with scope + cost + timeline delta
  • E-signature valid in all 50 states
  • Auto-adds to contract value + rebalances pay schedule
  • Work-in-progress photo attached as evidence
  • Per-job CO history with running totals
Mid-remodel, Mr. Park decides "while you're at it, do the bar too". Snap a photo, open Olynx, generate CO #3 for $3,400 (+ 4 days). Mr. Park signs from phone in 2 min. Contract auto-bumps to $87,400.

per pay app

AIA G702/G703 + Stripe Connect splits

For $50K+ jobs the customer/bank requires AIA G702/G703 — by hand it's 2 hrs per app. Admin takes 3 days to send. Bank pays 30 days later. Your electrical sub bills $4,800 — you owe them but customer hasn't paid your draw. Cashflow dies.

Olynx auto-generates AIA G702 Application + G703 Continuation Sheet at milestone close with schedule of values, 10% retainage, separated stored materials, approved COs. Stripe Connect auto-splits to subs by % when customer pays. Late fees auto-calculated. HMAC Client Portal — customer sees progress + photos + pays.

  • G702 Application + G703 Continuation Sheet auto-generated
  • 10% retainage per line + final release
  • Stored materials separate from work in place
  • Approved COs auto-rebalance the SOV
  • PDF to customer + ACH on collection = healthy cashflow
Close Phase 4 of the Park remodel. Olynx generates G702 + G703: work in place $51,420, retainage $5,142, previously billed $32,800, this period $18,620. PDF to customer 12:14 p.m. ACH lands in 15 days.

Sub Portal — subs without seeing your data

Plumber texts you "when do I start Park?". Drywaller asks "is the plumber done?". 4 subs × 6 texts/day = 96 messages. Your day goes answering, not building. And subs see contract value info they shouldn't.

Olynx Sub Portal: each sub has their own login and only sees their assigned jobs — not all your data. Progress photo upload + phase checklist, sub invoice submission with auto-routing to your approval queue, 1-to-1 sub ↔ GC messaging without phone. Auto-pay to sub via ACH on invoice approval. Dependency alerts: drywaller sees when plumber finishes.

  • Sub login: only sees their jobs (not all your data)
  • Progress photo upload + phase checklist
  • Sub invoice submission with auto-routing to your approval queue
  • 1-to-1 sub ↔ GC messaging without phone
  • Auto-pay to sub via ACH on invoice approval
Plumber Antonio opens Olynx: 3 jobs this week. Finishes Park kitchen rough-in Tuesday, uploads 14 photos + marks complete. Submits $4,800 invoice. You approve from phone in 90 sec. ACH to Antonio in 24 hr.
