Manage contracts with contractors, participants, change orders, retainage and acts in one system. Contractor gets a link, submits acts online, you approve — full traceability.
Word docs in folders, retainage calculated manually in Excel, contract changes lost in email chains — this is the reality of most construction firms. Specialized software turns this chaos into a controlled process.
Client wants additional work, you quote it in email. Six months later no one remembers agreed changes. Change orders with approval workflow document everything.
Retainage calculated in Excel, release forgotten. Result — held payments, unhappy contractors. Retainage management automates the process.
Contractor has no access to your system, so they write acts in Word and email them. You re-copy. Time wasted, errors inevitable.
What's percent complete on each contract? How much more needs doing? Without Work-in-Progress snapshots these questions go unanswered.
Construction Hub covers the full contract lifecycle with contractors — from signing to final acceptance.
Each contract linked to site, office, client, contractor, tender (if won from tender). Value, currency, dates, payment terms, warranty period, delivery terms — all structured.
Add participants (contractor, client, subcontractor) with invitation tokens. Each gets email and unique secure link for online interaction with the contract.
Contractor proposes change order (additional work, price change), you approve or reject. Full audit trail of every request and decision.
Automatic retainage calculation on every act. Release requests (request → approve → release) linked to proformas and tracking of remaining amounts.
Generate WIP snapshots — completion percentage, earned revenue, cost tracking. WIP history per point in time. Reports for accounting and bank.
Contractor submits acts directly via their link. You review, approve, sign or reject — all with audit trail and timestamp.
Four steps from contract to completion:
Create from scratch or from a won tender (pre-fill). Fill parties, site, value, timeline, payment terms, warranty period, retainage percentage.
Add participants with email — they receive invitation tokens. Accept or decline participation. Each with a specific role (CONTRACTOR, CLIENT, SUBCONTRACTOR).
During execution the contractor submits acts online, and as needed — change orders. Every request goes through approval workflow before taking effect.
On each act retainage is auto-calculated. At the end (or on conditions) contractor requests release, you approve, linked to proforma.
Construction Hub is suitable for any firm working with multiple contracts:
You manage dozens of subcontract agreements (MEP, HVAC, electrical). Each with change orders, retainage, acts. Centralized software makes full control possible.
You receive contracts from GCs. You need to track real status of each, submit acts quickly, monitor retainage.
You commission GCs and have many change orders during execution. You need full approval workflow and audit trail.
You manage contracts on behalf of the investor (PROJECT_MANAGEMENT type). Control execution, sign acts, approve change orders.

|---|---|---|
| Storage | Files on computer | Centralized with versions |
| Change orders | Email chains | Approval workflow with audit |
| Retainage | Manual in Excel | Automatic on every act |

| WIP reports | Manual calculations | Automatic snapshots |
| History | Files with dates | Full audit trail |
Construction Hub supports CONSTRUCTION, PROJECT_MANAGEMENT (on behalf of investor), RENTAL and other types. Each with different fields and lifecycle.
On each act a percentage retainage is auto-calculated. You have a dashboard with total held amount, you can request release (request → approve → release) with linking to a proforma.
Change orders are contract modifications during execution — additional work, price change, scope change. They go through formal approval workflow (submit → review → approve/reject) with full audit trail.
Add the contractor as a participant and enable public sharing. Contractor receives email with secure link, enters without registration and submits acts directly. You approve or reject.
WIP (Work-In-Progress) snapshots show contract completion percentage, earned revenue, remaining work. Generated periodically for accounting, bank, or audit.
