Free Solidity Developer
Service Agreement
Stop wasting your high-value engineering hours on the soul-crushing task of manually chasing payments when you should be focused on securing the protocol.
Pro Contractor Tip
Ensure your Master Service Agreement includes a specific 'IP Hold' clause, stating that the license to deploy or use the smart contract code is only granted upon receipt of payment in full.
Why use a written agreement?
Handshake deals are risky. As a Solidity Developer, "scope creep" is your biggest enemy. A clear agreement ensures everyone agrees on the deliverables before money changes hands.

2. Scope of Services
The Contractor shall provide the following deliverables:
- Subject: Quick Check-in: Invoice #[Invoice Number] for [Project Name] Hi [Client Name], I hope your week is going well. I’m sending a quick note to ensure you received the invoice for the [Phase/Sprint] of the [Project Name] smart contract development. It looks like it’s just a few days past due, and I wanted to bring it to the top of your inbox in case it was an oversight during the current sprint. Please let me know if you have any questions or if the payment is already in transit. Best regards, [Your Name]
- Subject: Urgent: Follow-up on Overdue Invoice #[Invoice Number] Hi [Client Name], I am following up on invoice #[Invoice Number], which is now 15 days past due. As per our signed agreement, payment terms are [Number] days from the date of issuance. To ensure we stay on track with the upcoming mainnet deployment and audit schedule, I need to get this balance cleared immediately. I’ve re-attached the invoice for your convenience. Please confirm when I can expect the funds to reach my wallet/account. Regards, [Your Name]
- Subject: FINAL NOTICE: Stop-Work Order for [Project Name] / Invoice #[Invoice Number] Hi [Client Name], Despite my previous reminders, Invoice #[Invoice Number] remains unpaid and is now 30 days past due. Per the terms of our contract, I am now required to issue a formal stop-work order. All development, testing, and deployment activity for [Project Name] will be paused effective immediately until the outstanding balance is settled. Work will resume once the payment is confirmed. Please process the payment today to avoid further disruption to the project timeline and the scheduled audit. Sincerely, [Your Name]

Frequently Asked Questions
How do I handle a client who stops responding once the smart contracts are on-chain?
This is a common friction point in Web3. Instead of sending manual, emotional messages, using an automated Dunning Engine provides a neutral, persistent 'robot' presence that follows a strict escalation logic. This removes the personal stress and signals to the client that your billing is a professional process that cannot be ignored.
Is it risky to issue a stop-work order when a project is in the middle of an audit?
While technical momentum is important, your business health is a priority. An automated Dunning Engine helps manage this risk by delivering pre-set warnings long before a stop-work order is triggered, ensuring the client has ample opportunity to pay before the 'pause' becomes necessary for your protection.
How can I maintain a 'friendly' developer relationship while still being firm on my rates?
The best way to preserve the relationship is to separate the 'creator' from the 'collector.' By employing an automated system to handle dunning (payment reminders), the software becomes the 'bad cop.' This allows you to continue discussing technical architecture and code with the client while the system handles the cold reality of accounts receivable.
