Why it matters
Without it, misattributed costs, hidden overruns, and unvetted price changes can erode margins and complicate client negotiations, risking board approvals and insurance underwrites.
From design to safety
Design
Design pricing philosophy and data feeds
Define data sources, establish acceptable margins, and lock in rate cards and material libraries for every project. In addition, map provenance notes, such as period and technique, to cost drivers. Establish digital folders for supplier warranties and material compatibility charts.
- Project cost diary
- Rate card master
- Material catalog
Build
Build cost-tracking pipelines
Ingest time entries, material orders, subcontractor invoices, and change orders to assemble a live project cost model. Validate subcontractor rate validity against approved vendors list; attach scanned invoices and purchase orders.
- Timesheet system
- Material purchase orders
- Change order log
Operation
Operate on real-time profitability view
Monitor project burn, update quotes, and trigger alerts when margins dip below targets. Use live dashboards to forecast remaining hours and flag unplanned tasks for re-quoting.
- Live dashboard
- Job progress tracker
- Quote database
Maintenance
Maintain cost data hygiene and rate integrity
Regularly reconcile invoices, adjust rate cards, and refresh material costs to keep the model accurate. Schedule data quality checks and archive obsolete data with rationale.
- Cost reconciliation cycle
- Rate card review
- Vendor cost library
Safety
Safeguard compliance and governance
Record approvals, maintain audit trails, ensure VAT/CITES compliance where applicable, and protect client data. Maintain data governance records for access controls and archival compliance.
- Approval log
- Audit trail
- Data protection controls

Worked example
Pricing a mid-range restoration with contingency
Illustrative scenario with sample data.
The piece is a Victorian ramble table undergoing veneer repair, inlay restoration, and glue-lamination across two drawers, with minor brass fittings to tighten.
Signal in
project_id: R-2045, client: Acme Estate, baseline_hours: 72, rate_card_id: RC-11, material_cost: 420, subcontractor_cost: 680, contingency: 15%, currency: GBP, exchange_rate: 1.00, material_supplier: HM Fine Woods
System out
quote_id: Q-2045A, revised_margin: 22.3%, new_estimated_cost: 1980, notes: 'contingency applied for inlay complexity and veneer match', client_ack_required: true, suggested_follow_up: 'review brass fitting tension and surface patination'
Human sign-off: The estimator approves the revised quote after a brief review of the change factors and authorizes the update to client communications. Review completed by the studio manager and logged in the change order system.
How to roll it out
Phase 1
Weeks 1 to 4: Baseline
Establish data feeds from timesheets, PO system, and change orders; set initial margins and rate cards.
Phase 2
Weeks 5 to 8: Pilot
Run pilot on 4 active projects; collect variance data and adjust automations.
Phase 3
Weeks 9 to 12: Scale
Roll out across the studio, finalize governance, and integrate with invoicing.
Where people stay in charge
- Only a qualified estimator or studio manager may approve rate card changes and margin targets; unauthorised adjustments risk mispricing.
- All changes must be captured in the change order log with validated client acknowledgment before invoicing.
- Rate card governance requires quarterly sign-off by financial controller and senior conservator; deviations trigger audit review.
Questions owners and crews ask
How should I choose which costs to include in AI job costing for restoration?
Include all direct labor, material, subcontractor, and change-order costs tied to the project, plus a defined contingency, to capture true project economics and support defensible quotes.
Can AI help me explain price changes to clients after the project starts?
Yes. The system generates an auditable change order with cost impact, client communication notes, and revised schedule impacts for signed approval.
How does AI handle variability in material prices for antiques?
The model tracks material price histories, flags variances, and suggests revised estimates or substitutions that preserve restoration integrity and client expectations.
What records should be kept for compliance and insurance?
Maintain an approval log, cost trails, quotes, invoices, and change orders linked to project IDs, stored securely and accessible for audits and claims.
