A customer who is 60 days late is not always a customer who will never pay. Often they are a good client with a cash-flow squeeze, and a well-built payment plan can recover the full balance while keeping the relationship intact. A poorly built one just delays the problem. Here is how to do it properly.
When should you offer a payment plan?
A payment plan makes sense when the customer is willing but unable to pay in one go. Offer one when:
- The customer acknowledges the debt and is not disputing the invoice.
- They have a track record of paying, or a clear reason for the shortfall, such as a late payment from their own client.
- The balance is large enough that a lump sum is unrealistic.
- The alternative, a collections agency or a write-off, would cost you more than waiting.
Do not offer one when the invoice is disputed (settle the dispute first), when the customer is unreachable, or when there are signs of insolvency. Those cases need a different route, and possibly legal advice.
What terms should the plan include?
Keep the structure simple enough to track and firm enough to enforce.
- Total amount owed: confirm the exact balance, including any agreed late fees or interest.
- Number and size of installments: equal amounts are easiest to follow. Most plans run three to six months; longer plans raise your risk.
- Fixed due dates: tie them to the customer's payday or payment run, such as the 1st and the 15th, rather than vague end-of-month wording.
- Payment method: bank transfer, direct debit or a card on file. Automatic payments sharply reduce missed installments.
Ask for a deposit
Request an upfront payment, commonly 10 to 25 percent of the balance. A deposit proves good faith, reduces your exposure immediately and gives the customer a reason to keep the plan alive. If they cannot find even a small deposit, treat that as a warning sign.
Put it in a written agreement
Never rely on an email chain or a phone call. A short written agreement, signed or clearly accepted by someone with authority, should state:
- The invoice numbers and the total balance covered.
- The deposit, each installment amount and every due date.
- That the original debt remains valid and the plan is a concession, not a discount.
- Whether late fees or interest are paused, waived or still apply.
- That new orders may be on hold or on prepayment terms until the plan is settled.
Have it checked against local law, since rules on interest, fees and enforceability vary by country.
Include a default clause
The default clause is what gives the plan teeth. Define exactly what counts as default, for example one installment missed by more than five to seven days, and what happens next. Typically the full remaining balance becomes due immediately, any waived fees are reinstated, and you may resume normal collection steps. Include a short grace period so a single bank delay does not blow up the agreement, but make the consequences clear and apply them consistently.
How do you track installments and send reminders?
Most payment plans fail not from bad intent but from poor follow-up. Once the agreement is signed, treat each installment like its own small invoice:
- Record the schedule against the customer account so the remaining balance is always visible.
- Send a friendly reminder three to five days before each due date.
- Confirm every payment received, along with the new remaining balance.
- Follow up the day after a missed installment, not a week later. Early contact is what separates a hiccup from a default.
- Review all active plans in your aging report every week.
Keep the rest of the account in order too. Make sure new invoices are paid on time alongside the plan; otherwise you are only adding to the pile.
Common mistakes to avoid
- Verbal-only agreements that nobody can prove later.
- Plans that are too long, which stretch your risk for little gain.
- Skipping the deposit and giving up your leverage.
- Not enforcing the default clause, which teaches customers that the dates are optional.
Where software helps
Spreadsheets and calendar reminders work for one or two plans, then they start to slip. FulcrumGrid Collection can track each plan's installments against the customer's invoices, send automatic reminders before each due date, and flag a missed payment the next day so you can follow up while it is still easy. It does not replace your judgment about who deserves a plan, but it takes care of the repetitive tracking that makes plans succeed.
Frequently asked questions
How long should a payment plan for overdue invoices last?
Most plans run three to six months. Shorter plans recover cash faster and carry less risk; anything beyond a year should be rare and backed by a larger deposit or extra security.
How much deposit should I ask for?
A deposit of 10 to 25 percent of the balance is common. It shows good faith and cuts your exposure right away. A customer who cannot pay any deposit may not be able to sustain the installments either.
Should I charge interest or late fees on a payment plan?
That is your choice, but state it clearly in the agreement. Many businesses pause fees while the plan is on track and reinstate them on default. Check local rules on what you can charge.
What happens if the customer misses an installment?
Your default clause decides. Usually, after a short grace period, the full remaining balance becomes due and normal collection steps resume. Contact the customer the day after the miss so you can resolve it quickly.
