What the Act says about the notified sum
Under section 111 of the Housing Grants, Construction and Regeneration Act 1996, once the notified sum is fixed by a payment notice (or the payee's notice), the payer must pay it by the final date for payment unless a valid pay less notice is given in time.
Paraphrased. Applies to construction contracts within the Act, in England and Wales. Not legal advice.
The notified sum is the amount in the payer's payment notice or, where the payer gave none, in the payee's notice (sections 110A and 110B). The duty has limits, which section 111(8) to (10) sets out.
PayCycle tracks the dates from the notices and terms you record. It cannot see what the other party serves.
Check a notice you have served or received with the free Notice checker. No account needed.
Payment terms you confirm and lock
PayCycle suggests the payment terms from the contract you upload, or you type them in. You review, edit and lock each term before it is used.
Where your contract goes
Your project data and uploaded files are stored in Frankfurt (EU). Our application servers, and our sign-in, AI and email providers, are in the United States.
To read a contract, PayCycle sends that document to our AI provider, Anthropic, in the US. Anthropic states that it does not train on commercial API data.
Deleting your account removes your data from the live application immediately.
Notices drafted for you to check and sign
PayCycle drafts the Payment Notice and the Pay Less Notice from your assessment, with the due date and the final date for payment taken from the terms you confirmed. You check, sign and send them. It does not send notices for you.
Each date worked out and kept in view
From the terms you confirm, PayCycle works out the date for each notice and the final date for payment, and reminds you before each one.

Common questions
What do I need to start?
A copy of your contract as a PDF and one application for payment. You can also type the payment terms in yourself. If you would rather look around, the live demo needs no account and has AI features switched off.
Where is my data stored?
Your project data and uploaded files are stored in Frankfurt (EU). Our application servers, and our sign-in, AI and email providers, are in the United States. So some processing happens outside the UK and EU, under the transfer safeguards listed in our Privacy Policy. The security page has more.
What does the AI do with my documents?
It reads what you send it and suggests. You review and approve each figure and notice. It does not issue notices or change your records.
For each AI action, the document or figures for that action are sent to our AI provider, Anthropic. Anthropic states that it does not use commercial API inputs or outputs to train its models and does not retain them by default; content flagged by its safety systems may be kept longer. Read its published data-retention policy.
Is this legal advice?
No. PayCycle gives you contract information, drafts and reminders for you to check. You review, sign and send each notice. For advice on a dispute, speak to a construction lawyer.
What does it cost, and what happens when the trial ends?
Free plan: £0. Solo: £39 a month. Practice: £149 a month.
Every paid plan starts with a 30-day free trial. No card up front. If the trial ends without a card, your account drops to the Free plan. Your data is kept and the AI features are off until you subscribe.
