CHAPTER 4
Payment Terms &
Cash Flow Strategy
Payment terms define when and how you get paid. Clear terms protect your cash flow, reduce confusion, and set professional expectations from the start.
Choosing the right payment structure depends on your type of work, client relationship, and project size.
1. Net 15 vs Net 30
“Net” terms specify how many days the client has to pay after the invoice date.
- Net 15 – Payment due within 15 days
- Net 30 – Payment due within 30 days
Net 15 improves cash flow and reduces waiting time. Net 30 is common for larger companies with longer internal approval processes.
Shorter terms generally mean faster payment. Choose terms that align with your business needs and industry standards. With Invoice Fly, you can set clear due dates directly on each invoice to avoid misunderstandings.
2. Deposits & Retainers
For larger projects, requesting a deposit helps reduce risk.
Common structures include:
- 25%–50% upfront before work begins
- Milestone-based payments
- Monthly retainers for ongoing services
Deposits ensure commitment from the client and help cover initial costs. You can create separate deposit invoices or milestone invoices within Invoice Fly to structure payments clearly.
3. Partial Payments
In some cases, clients may pay in installments. Partial payments allow flexibility while keeping work moving forward. When using structured invoicing, you can record partial payments and track remaining balances accurately.
Clear documentation helps prevent disputes and ensures both parties understand the outstanding amount.
4. Late Fees (When to Use Them)
Late fees can encourage timely payment, but they should be used carefully.
If you choose to apply late fees:
- Clearly state the policy in your payment terms
- Keep fees reasonable and compliant with local regulations
- Communicate professionally before applying penalties
Often, clear reminders are enough to prompt payment. Invoice Fly allows you to define payment terms and send reminders to help reduce overdue invoices.
5. Early Payment Incentives
Offering a small discount for early payment can improve cash flow.
For example: 2% discount if paid within 7 days
This can be especially useful for recurring clients. Early payment incentives should be clearly stated on the invoice so the client understands the benefit.
Strong payment terms create predictable cash flow.
Predictable cash flow creates stability.
In the next chapter, we’ll look at how to manage invoices after they’re sent, including tracking payments and handling overdue accounts.
