Who it’s for

Planyard is built for contractors, QSs and commercial teams working under JCT contracts — from Minor Works to Design and Build and Standard Building. If you’re tired of juggling valuations, variations and budgets across multiple spreadsheets, this is the upgrade.

How Planyard Manages JCT Contracts from Start to Finish

Set up your JCT contract once — then track variations, valuations, retention and valuations in a single structured workflow.

Set up your JCT main contract in minutes

Import your contract sum, retention rules and scheduled line items. Link everything to the project budget so your contract and cost codes always speak the same language.

Cost code linking

Connect contract line items directly to your budget

CIS-ready workflows for JCT projects

JCT contracts often run side-by-side with CIS requirements, which means every valuation, deduction and subcontractor payment needs to stay consistent with both the contract and HMRC rules.

Planyard keeps your JCT variations, valuations and retention aligned with accurate CIS deductions, so commercial teams and finance teams always work from the same figures.

Accurate CIS deductions

Every approved subcontractor valuation calculates CIS correctly, with no manual adjustments.

Clean record-keeping

CIS summaries sit in accounting, valuations and payment history in Planyard for easy auditing.

Smoother reconciliation

Contract commitments, retention, variations and CIS deductions all match without re-checking spreadsheets.

Export-ready filings

Keep month-end and HMRC compliance running smoothly.

Problems We Solve

Manual JCT workflows create costly blind spots: mismatched variations, outdated contract sums, missed notice dates, inconsistent valuations and spreadsheets that never agree with each other. Planyard replaces all of this with a single, structured system that keeps JCT, budgets and subcontractor agreements perfectly aligned.

"I chose Planyard because it stood out as the most straightforward and intuitive option on the market. I really wanted a tool that would simplify our existing processes and make everything more efficient, rather than switching to a system that was far too complicated for us to use on a daily basis."

"For me Planyard is essentially the go to software for SMBs. There are other software packages out there that are a large investment upfront with a significant monthly cost. These are all potential solutions once you get to a very large business but they are not a solution for SMBs."

"Timewise, on a single project, I'd probably save 6 to 8 hours—essentially a full day every month. When it comes to processing monthly payments, it saves me a solid day, perhaps even a day and a half, just in sorting through the invoices. Saving a day and a half of my time means the system pays for itself time and time again."
