Frequently asked questions
- How long should I wait before collections?
- After due date, run reminders for two to four weeks, then a formal demand. Move faster on large balances or repeat offenders.
- Will collections ruin the relationship?
- Often the relationship is already strained. Professional agencies sometimes preserve more goodwill than angry DIY emails.
- Can I sell the debt instead of hiring an agency?
- Factoring unpaid invoices is rare for small freelancer balances. Agencies and attorneys are the usual paths.
- Should I report a client to credit bureaus?
- Commercial reporting has strict rules. Many freelancers use attorneys or agencies instead of DIY credit bureau reporting.
- What if the client claims the work was bad?
- Separate quality disputes from payment. Provide SOW sign-offs and offer good-faith fixes, but do not waive undisputed principal without analysis.
- Do I need a lawyer for small claims?
- Usually no—small claims is designed for self-representation. Bring organized documents and stay factual.
- Can I charge collection costs to the client?
- Only if your contract allows attorney fees or collection costs. Otherwise those expenses come out of what you recover.
- What about clients who disappear?
- Document delivery and attempts to contact. Bad debt treatment may apply; prevention beats chasing ghosts—use deposits next time.
- Is partial payment acceptance a settlement?
- Not automatically—state in writing whether accepting partial payment reserves your right to collect the balance.
