VariationFlow - 2026 Pricing, Features, Reviews & Alternatives

VariationFlow is variation, payment and commercial control software for specialist subcontractors working under main contractors: fit-out, dry lining, flooring, electrical, mechanical, fire protection, roofing and groundworks among them.

Site crews capture each change on an iPhone or Android phone in about a minute: photos, a voice note, the location and the requester's signature, with or without signal. The app runs in ten languages, so crews can use their own. The office prices the variation and submits it to the main contractor, who reviews it from a link with no account needed. Every variation ages on a register, amber at 28 days and red at 42.

VariationFlow tracks the deadlines that cost subcontractors money: the NEC4 subcontract's compensation event clocks, confirmation of verbal instructions under JCT, and Construction Act payment dates, pay less notices included. The cost value reconciliation (CVR) sets value from your valuations against cost by head, with your QS's forecast, on every job. UK organisations on a paid plan can send certified valuations to Xero, Sage Accounting or QuickBooks Online as sales invoices, which are marked paid when they are paid there.

QA Flow adds inspections, NCRs, snags, RFIs and hold-point sign-offs, signed off by link. Builder is a separate plan for domestic builders: quotes accepted online, extras the homeowner signs for, stage payments and invoices.

VariationFlow is sold in the United Kingdom and Switzerland. The Swiss edition runs in German and French, with variations, quotes and payment reminders in CHF, and tracks the four-month deadline for the builder's lien on every project.

Free for your first job: one project, two users, no card. Paid plans from £49 a month + VAT in the UK, and from CHF 79 a month in Switzerland.
