Question

What happens if I don't define an invoicing schedule in a contract?

My contract doesn't say when invoices should be sent, and now payments are all over the place. What problems can this cause, and do I have any protection?

Answer

If an invoicing schedule is not defined, billing and payments can become inconsistent and unclear. This often leads to delays, confusion, and cash flow issues.

Without clear timing, both sides may have different expectations about when invoices should be sent and paid.

What problems can this cause?

Missing or vague invoicing terms can lead to irregular payments and difficulty planning cash flow. Clients may delay payment simply because no clear deadline was set.

It can also cause disputes over when payment is due or whether an invoice was sent at the right time.

Do you still have any protection?

Yes, you may still have some protection. Even if the contract does not set a schedule, the law often requires payment within a "reasonable time" after services are provided and invoiced.

What counts as "reasonable" depends on the situation, including:

  • The type of work.
  • Industry standards.
  • How you and the client have handled payments in the past.

You can also set expectations through your invoices by including due dates and payment terms.

Following up with reminders or past-due notices can help. However, charging late fees or enforcing strict timelines may be harder if they were not agreed to in the contract.

What to do next...

  1. Start including clear due dates on all invoices.
  2. Set a consistent billing routine going forward.
  3. Communicate payment expectations in writing.
  4. Update future contracts to include an invoicing schedule.

What to consider in your specific situation

Missing invoicing terms can affect each case differently depending on your setup.

  • The wording of your existing payment terms.
  • Your past billing practices with the client.
  • The size and frequency of invoices.
  • Local laws affecting payment collection.
  • The client's payment habits and reliability.
