Project Mode + live Budget vs Actual
The pain
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.
What Olynx does
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".

Project Mode + live Budget vs Actual
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.
Change orders + sub COIs signed
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.
AIA G702/G703 + Stripe Connect splits
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.
Sub Portal — subs without seeing your data
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.
