Estimate from the specification
Plastering, render, EWI and dry lining systems need the correct materials, labour and site allowances — not just a single rate per square metre.
Built for UK specialist subcontractors
Job management software for plastering, rendering and dry lining subcontractors
Price the work, send a quotation, manage site paperwork and keep track of what needs paying — all within the same project record. SubCon Systems is designed around how specialist trade subcontractors actually work, not just how a general appointment diary works.
Plans from £19/month. Trial lasts 14 days. Card details required at checkout. Cancel before the trial ends to avoid the subscription charge.
One project, one record
From the first enquiry to the final invoice
A measured subcontract often runs over several weeks with changing access, labour and materials. These stages should not live in unrelated tools.
- 01
Record the enquiry and project
Keep the customer's details, site address and scope under one job rather than across several spreadsheets, inboxes and folders.
- 02
Measure, estimate and quote
Work from quantities and the specified construction build-up. Separate labour, materials, access and waste before preparing a customer quotation.
- 03
Keep site paperwork together
Attach the agreed quote, project documents, RAMS, contracts and updates to the same record so the office and site team can find them.
- 04
Track changes and payments
Record variations, raise invoices and review outstanding amounts and retention records without losing the history of the original job.
Designed for measured trade work
More than a generic invoice app
Keep RAMS and approvals with the job
The method, project documentation and variations should be visible with the agreed scope, not hidden in someone's inbox.
Protect the payment record
Record invoices, variations and retentions against the project so outstanding commercial items are easier to identify.
Typical subcontractor paperwork problems — and how SubCon helps
The quote has changed, but nobody can find the new scope
Keep the estimate, accepted quotation and later variations connected to one project, with a clear record of what changed.
The job is live, but the RAMS and paperwork are scattered
Keep project documentation, contracts and reviewed RAMS with the customer and site record instead of rebuilding files for each job.
The work is finished, but invoices and retention are hard to follow
Review invoices, payment status and retention information alongside the project rather than chasing totals across different files.

Questions from trade contractors
Is this software for subcontractors or main contractors?
SubCon is primarily aimed at UK specialist trade contractors who carry out the work: plasterers, renderers, external wall insulation teams and dry lining businesses. It brings their estimating, project records and commercial paperwork together.
Can I use it to estimate plastering or rendering from measured areas?
Yes. SubCon has trade-specific estimating workflows and a manual drawing take-off workspace. You should check the drawing scale and project specification before completing quantities and pricing.
Does it include quotations, variations, RAMS and invoices?
SubCon supports these project workflows. Prepare and review documents, keep them with the project and track commercial changes as the work progresses. Check which features are included in your chosen plan.
Does SubCon handle my accounting or automatically file CIS returns?
No. SubCon is for job management and commercial records, not a replacement for accounting software. Don't assume an accounting integration or HMRC filing is available.
