Complex fit-out projects need more than a spreadsheet
Commercial fit-out contractors managing multiple subcontractors, long project timelines and detailed cost management need a platform that keeps pace. Zigaflow was built for this.

Project management and cost control for fit-out contractors
Commercial fit-out projects involve dozens of moving parts - design teams, specialist subcontractors, long-lead materials and clients who change their minds mid-project. Staying on top of costs, schedules and communications requires real operational discipline.
- Most UK fit-out contractors operate as SMBs turning over between £500k and £10m annually.
- Project values typically range from £20k for small office refurbs to £2m+ for full commercial fit-outs.
- Contractors juggle multiple live projects simultaneously, each with separate subcontractors, suppliers, and timelines.
- Margin erosion from untracked variation orders and material cost overruns is a leading profitability problem.
- Many firms still use spreadsheets and email to manage quotes, procurement, and project progress tracking.
How it runs in Zigaflow
- Inquiry capture and qualificationNew project inquiries arrive via referrals, tender portals like Barbour ABI, architect introductions, or direct client contact.
- Estimate and proposal submissionDetailed cost estimates are built from labor schedules, subcontractor quotes, materials takeoffs, and preliminaries, then compiled into a branded client proposal.
- Project delivery and variationsOnce a contract is awarded, purchase orders are raised for subcontractors and suppliers, and a project program is set against agreed milestones.
- Invoicing, retention, and syncApplications for payment or stage invoices are raised against contracted milestones, with retention amounts tracked separately until practical completion and defects periods expire.

The problems we solve
Tender pricing takes weeks to compile
Detailed fit-out tenders require costs from multiple subcontractors and suppliers. Collating, checking and building these into a client proposal is a lengthy process.
Zigaflow manages the full tender process - issue RFQs to subcontractors, collate responses and build client proposals from a single platform.
Client changes destroy your cost plan
Design changes mid-project create a cascade of revised quotes, additional orders and disputed invoices. Without rigorous change management, margin evaporates.
Every change instruction is logged in Zigaflow with a cost impact. Variations are formally agreed before work proceeds and invoiced automatically.
Retention and stage payments are poorly tracked
Fit-out contracts often involve stage payments and retention.
Zigaflow milestone invoicing and retention tracking ensures every stage payment is claimed on time and retention is released when due.
