Charges and payment
Show in the document (¶30–36)
Red flag: Slow payment, a 3% deduction and no late-payment interest
90-day terms from month end, a 3% deduction from every invoice and the exclusion of statutory interest together move cost and cash-flow risk onto the Supplier.
“no interest shall accrue on late payments under the Late Payment of Commercial Debts (Interest) Act 1998”
In plain English
The Supplier invoices monthly and is paid within 90 days of the end of the month the invoice arrives, so up to about four months after the work. The Customer deducts 3% from every payment as a ‘supplier contribution’.

- What every clause means for you, and for them

Know where you stand before it matters
Most contract trouble starts long after signing: a renewal nobody noticed, a cap nobody read, a notice period that’s too long. Keep a plain-English reading of every agreement you rely on, with its exits and obligations in one place.
- How long it lasts, how it renews and the notice to stop it
- Who can end it, how, and what happens after
- Liability caps, insurance, and what the contract leaves out

Can they end this early?
Yes, but only the Customer can do so freely. It can end the agreement, or any Statement of Work, at any time on 30 days’ written notice. The Supplier can only end it for a serious breach that isn’t put right within 30 days, or if an undisputed payment is 120 days late and still unpaid 30 days after a reminder.

Sample: Master Services Agreement (UK)
Prepared by Sam Brightline. A plain-English reading to prepare for legal advice. It is not legal advice.
1The document
- Parties
- Hartwell Retail Group plc (“the Customer”)
Brightline Studio Ltd (“the Supplier”) Me - Governing law
- England and Wales“governed by and construed in accordance with the law of England and Wales” (17.1)
2What I need help with
We want this contract, but we need payment within 30 days, a cap on our liability and to keep our own templates. We have been asked to sign by Friday.
3Questions to ask
- Could the indemnity be limited to losses we cause, and capped?
- What does the 3% supplier contribution pay for?
-
01
Upload the contract
A PDF, a Word document or a scan, up to 20 MB, or paste the text. LegalSling reads it, numbers every paragraph, and notices tracked changes, comments and hidden text.

02
See the whole contract at a glance
A short summary with the red flags in order of importance, then the key facts: how long it lasts, how it renews, when you’re paid and how either side can end it. Each one links to its clause.
-
03
Every clause, read from both sides
What each clause says in plain English, what it means for you and for them, and which way it leans. Tell it which side you’re on and it marks what counts against you.
-
04
Red flags, in the words that matter
Terms that are one-sided, unusual or may go further than the law allows are flagged, with the exact words highlighted in your document. Every quote is checked against the text.
-
05
Ask in your own words
“Can they end this early?” Answers come only from the document, with links to the paragraphs they rely on, and say so when the contract is silent.
-
06
Brief your lawyer
Your notes, the red flags and the questions to ask, in a brief you can print, save as a PDF or paste into an email. The time you pay for goes on advice, not on reading.
AI that shows its working
AI is good at reading, but it can be confidently wrong. These checks run on every analysis, so you can trust what you see and see what to check yourself.
-
Every quote is found in your document
The words shown for each red flag, key term and the governing law are looked up in the contract’s text. A quote that can’t be found isn’t shown as fact.
-
Every reference points somewhere real
Paragraph references must exist and clauses can’t overlap, so each point takes you to the right place in the contract.
-
“Not stated”, never a guess
The governing law is taken only from the contract’s own words. If it doesn’t say, you’re told so, and clues are labelled as clues.
-
The document is read, not obeyed
A contract is text to explain, never instructions. Hidden text aimed at an AI reviewer is flagged as a warning.

A contract means what it says, not what someone tells you it means
“Like a lot of small business owners, I’ve been through a contract dispute. Mine took more than a year to resolve. I had to figure out much of it for myself: where I actually stood, what my options were, and what was worth paying a lawyer for. It was expensive, exhausting, and one of the hardest periods for my business since I started it.”

Frequently asked questions
What is LegalSling?
LegalSling is an AI contract review tool for small businesses, freelancers and agencies. You upload a contract you’ve been sent and it explains every clause in plain English, shows what each one means for each side, flags terms that may go too far and prepares a brief for your lawyer. It explains contracts; it doesn’t give legal advice.
Can AI review a contract?
AI can read a contract, explain it in plain English and spot terms that are one-sided or unusual, quickly and at low cost. It can also misread context or miss something, so treat it as a careful first reading. LegalSling checks every quote it shows against your document and says “not stated” rather than guessing, but for anything important, use the analysis to brief a qualified lawyer.
Does LegalSling replace a lawyer?
No. LegalSling explains what a contract says and flags points to discuss, but it doesn’t tell you whether to sign or what to negotiate, and it isn’t a law firm. It helps you work out which points need a lawyer’s advice, and makes that advice quicker to get: you can send your lawyer a brief with the red flags, your notes and the questions to ask.
Can lawyers use LegalSling?
Yes. Solicitors, in-house teams and paralegals use it for a structured first pass: every clause mapped and explained, issues linked to the paragraph they come from, the governing law quoted from the text, and missing schedules or blanks pointed out. It’s a head start on the reading, not a substitute for professional judgement.
Which contracts can it review?
Business contracts you’ve been sent, such as services agreements, statements of work, consultancy and agency agreements, supply agreements, NDAs and terms and conditions. Upload a PDF (scanned PDFs work too), a Word document or plain text, up to 20 MB. It’s built for contracts governed by UK, EU or US law, and explains others with general context only.
Does it work for UK, EU and US contracts?
Yes. It’s built for contracts governed by the law of England and Wales, Scotland, Northern Ireland, EU member states and US states. LegalSling reads the governing law from the contract itself and shows you the words it relied on. If the contract doesn’t say which law applies, it tells you so rather than guessing.
Is my contract kept private?
Yes. Your documents are visible only to your account, stored encrypted and used only to produce your review. To create the analysis, the text is processed by Anthropic’s Claude AI. You can delete any document, or your whole account, at any time. Read how we handle your documents.
How much does it cost?
You start with 500 free credits as soon as you sign up, with no card needed. After that you buy credits in packs from £50 in the UK, or $60 elsewhere, with no subscription, and they never expire. A 10-page contract uses about 1,900 credits (around £19, or $23) and a question about 64 credits. See pricing.
