The Year-End Collections Sprint: How to Get Paid Before December 31

December is when your cash needs peak and your clients’ budgets close. A focused six-week sprint, starting now, is the cheapest financing you have.

Every December, Bolivian SMEs face the same squeeze at once: aguinaldo, year-end supplier payments, taxes and often a slower January. The invoices your clients owe you are the one source of cash you control without borrowing. If you wait until the last week of the year to chase them, you are competing with every other supplier doing the same thing. Starting now gives you about six weeks to turn receivables into cash.

1. Week 1: Know exactly who owes you

Pull your accounts receivable aging: every open invoice grouped by client and by how overdue it is. Then rank clients by amount owed and by age. In most businesses, a small handful of clients hold most of the money. Those are your sprint targets, not the long tail of small balances.

Example aging report (illustrative)
Not yet dueBs 180,000
1–30 days overdueBs 95,000
31–60 days overdueBs 60,000
Over 60 days overdueBs 45,000

If three clients account for Bs 120,000 of the Bs 200,000 overdue, your sprint is three conversations, not two hundred messages. Measuring your DSO now gives you a baseline to compare against in January.

2. Week 2: Make contact, with a specific ask

A reminder that says “please pay” gets ignored. A message that says “invoice 1234 for Bs 18,500, due September 30, can you confirm the payment date by Friday?” gets answered. Include the invoice number, amount, due date and a specific date you need back. Call the large debtors, not just message them, and confirm in writing afterward.

3. Weeks 3 and 4: Time your asks around your clients’ cash

Your clients are also paying aguinaldo, which in Bolivia is due by December 20 (see our aguinaldo guide). Many of them will prioritize payroll first and suppliers after. That makes November your best collection month: ask for payment before your clients’ cash is committed, not after. If you wait until mid-December, the answer is often “after the holidays.”

4. Use a discount only when the math works

An early-payment discount can be a good deal or an expensive one. Offering 2% off for payment within 10 days instead of 30 days sounds small, but the math says otherwise:

The real cost of a 2% early-payment discount (10 days vs 30 days)
Discount on a Bs 50,000 invoiceBs 1,000
Cash received 20 days earlierBs 49,000
Equivalent annual cost of that moneyabout 37%

The calculation is 1,000 ÷ 49,000 × (365 ÷ 20) ≈ 37%. If you can borrow or cover the gap at a lower rate, a discount is expensive financing. If you are about to miss payroll or a key supplier payment, it may still be the right call. Decide the maximum discount in advance, give it a deadline, and offer it only to clients who are otherwise reliable.

5. Weeks 5 and 6: Payment plans and the final push

Do not forget your own taxes: The IVA on your invoices is part of your filing calendar even when the client has not paid, so late collections squeeze cash twice. Build the gap into your December cash plan.

6. Close the loop in January

On the first working days of January, rerun your aging report and compare it to week 1. Note which clients paid after one reminder, which needed three, and which never answered. That list is your credit policy for next year.

How Contably helps: Contably shows your open invoices by client and by age in one view, and automates reminders before and after the due date, so the sprint becomes a routine rather than a December emergency.
