Hi everyone!
If you’ve ever struggled with cash flow, the discussion among building designers at the December AIBD Coffee with Bernie might be of great help. All feedback is welcome!
As building designers, we must apply effective cash flow management to sustain our businesses. Challenges such as irregular payments, scope changes, and unforeseen expenses highlight the need for proactive strategies and clear communication. Sometimes this is hard to do, especially if you are a sole proprietor, but you can do it!
When you leverage tools such as QuickBooks, Zoho Books, and detailed spreadsheets, you can simplify your invoicing and payment tracking. Having consistent billing practices that you tie to project milestones can help you stabilize cash flow. And when you implement secure payment methods, thoroughly vet your potential clients, and use robust contracts, you can protect your work and mitigate risks.
It might sound like a lot, but having clear procedures for handling changes, reserving funds, and setting client expectations can foster trust and financial stability. By adopting these strategies and tools, we all can confidently navigate the complexities of cash flow while maintaining our professional integrity and keeping our clients satisfied!
Strategies for Maintaining Consistent Cash Flow
Here is a summary of the key points discussed about financial practices and avoiding common pitfalls.
Payment Structures:
- Require retainers for each phase, and apply them to invoices when you complete that phase.
- Use milestone billing (35%-35%-30%, or 50% upfront and balance before engineering).
- All payments non-refundable.
- Include a clear scope of work and payment schedule in contracts.
- Ensure that deliverables are tied to payments, and don’t release plans until payment clears.
Timely Billing:
- Send invoices promptly, and have payments due upon receipt.
- To minimize risks, use smaller, frequent payments.
- Require final payments before key deliverables, such as engineering submission.
Legal and Protective Measures:
- File liens for unpaid work, and ensure proper documentation and timelines.
- Include a “Termination Adjustment Payment” clause (30% of incurred charges if a client cancels).
Payment Methods and Tips:
- Venmo, PayPal, Zelle, ACH transfers, checks, and credit cards (with added 3% fee for card payments).
- Accept ACH payments only from trustworthy, repeat clients.
- Allow clients to opt for check payments to avoid fees but clarify potential delays.
- If payment issues arise, explore lien options.
Client Vetting and Contract Practices:
- Trust your instincts. Decline untrustworthy or scam-like projects.
- Protect your business with non-refundable retainers and clear service agreements. Aim for concise formats such as a one-page proposal and a two-page contract.
- Regularly review updates on project scope and payment expectations.
Other Recommendations:
- Use templates and resources, such as the Designer Docs that AIBD provides.
- For iterative or complex projects, bill hourly.
- For clarity and cash flow continuity, issue monthly invoices.
Handling Changes While Maintaining Cash Flow
When billing for changes:
- Charge extra for continual changes.
- Include clauses in your contracts that define reasonable changes.
- Use an hourly billing model for revisions beyond the initial scope.
- Offer a flat fee for initial phases, such as the conceptual phase with one revision, and bill additional changes at an hourly rate.
Communication and Clarity:
- Clearly outline the scope of work so that you manage client expectations.
- To ensure fairness, notify clients when changes are out of scope.
- Avoid itemizing your hours in your invoices. Instead, use a monthly sum total or minimum increments of one hour.
- Communicate procedures upfront and adhere to them.
Cash Reserves:
- Aim to keep at least three months of cash reserves on handto reduce dependency on immediate cash flow.
Employee and Subcontractor Payment Plans:
- For teams or subcontractors, establish clear monthly payment plans to maintain financial predictability.
Advice for New Business Owners
Contracts and Procedures:
- Always have a signed contract before starting work.
- Clearly define your scope of work and billing procedures in the contract.
- Do not hesitate to invoice or request payment for completed services.
Scam Awareness:
- Vet clients carefully (e.g., check property ownership).
- Request non-refundable deposits for added security.
- Stay vigilant against digital scams (e.g., QR codes, fake ACH payments).
Client Relationships:
- Payment signifies appreciation for services; ensure clients understand this.
- Train clients on your billing expectations to avoid misunderstandings.
