A Strong December Is Not a Cash Position

Most cash problems arrive unannounced. This one does not. Seasonal customers post their best numbers just as their cash is most exposed, and your platform sees the numbers, not the cash. Orders are up, volume is up, everything on your dashboards looks healthy.

You have the data and the window. Before the holiday break you can see who sold a lot but has not been paid, who bought stock early and who has a large bill at the start of the year. Those customers are worth a call, and this guide shows how to find them.

Why December Misleads

The mismatch is timing. Costs come first, cash comes later, and January's fixed bills arrive on the first.

What you see in December	What cash may be doing
Record order volume	Stock and extra labour were paid for in the autumn
Invoices issued on every order	Customers pay on terms, say 30 to 60 days, so much of December's cash lands in February
Strong revenue on the platform	Seasonal staff and extra shifts raise payroll
A quiet support queue	Rent, insurance and tax payments can all fall due early in the new year

A Worked Example: Northwind Supply

Northwind Supply is a wholesale distributor that sells through a B2B marketplace. Its orders are lumpy and its customers pay on 45-day terms. All figures are illustrative.

Northwind Supply in mid-December

The surface: December is its biggest month, with about $210,000 in orders shipped. The marketplace shows it as one of your strongest sellers.

Underneath: it paid suppliers about $120,000 in November and December to stock for the rush. On 45-day terms, most of December's invoices will not be collected until mid-January at the earliest.

The January calendar: rent and insurance of about $18,000 on the first, payroll of about $24,000 on the fifth. Cash on hand at the end of December is about $31,000.

The read: cash covers payroll but not both bills unless two large receivables arrive early. The best month of the year leaves the business exposed in the first week of January.

Find Them by Hand

List the customers whose December is much bigger than their autumn average. Those are your seasonal ones.
Next to each, write the date of their next payroll or largest known bill.
Add open invoices and when they fall due. Receivables due after the bill date do not help the bill.
Flag customers where known cash before the bill date is smaller than the bill.
Sort by how soon the bill lands and start at the top.

If you hold bank-connected data, add deposits and balances, and rank by days of cover instead. How to Build a 13-Week Cash Flow Forecast shows the same logic for one business.

Three Kinds of January Problem

Kind	What it looks like	A helpful first conversation
Seasonal and expected	A strong December followed by a known quiet January	How are you planning for the dip?
One-off bill	A large payment due early in the month	Is the timing of that bill a problem?
Longer slide	Deposits falling since autumn	How are you feeling about the next few months?

The third kind matters most. A business already slipping has the least room to recover in January. Your customers show trouble in their money before they show it to you, and this is the season it matters.

What to Say, and When

Reach out about two weeks before the break, then once more as it ends. Keep it short and easy to ignore. An owner who does not reply is not saying no. They may be busy.

Hi Marco, I hope the holiday rush went well. I was looking at the next few weeks and noticed the supplier bill on the first lands just before payroll. Want to talk through the timing? There are a few ways to smooth it out.

A sample note. Short, specific and without promises.

Capital Can Make January Worse

Slate funds businesses with merchant cash advances and credit lines, through the platforms they already use. That honesty matters here, because the kind of capital changes the answer.

Any capital has to be repaid. If a customer takes it in December, it is repaid out of a thin January, which can deepen the problem it was meant to solve. A standing credit line helps because the limit is already there before the gap arrives. Business Line of Credit vs Cash Advance sets out the difference, and How Embedded Capital Works for Platforms covers how your platform should talk about each. Say that capital may be available, never state an amount, an approval or a timeline, and let the business apply.

Log what happens. Write down who you contacted, what they said and whether they were short in January. Next year you will start with a list of which customers are most exposed and which notes worked.

Common Questions

Should I offer capital to everyone who is short?

No. Some gaps are timing and will close when a receivable lands. Read the cause and offer it where it fits.

Can I do this without any new tooling?

Yes. The five-step method above works from your order and invoice data and a spreadsheet. Bank-connected data makes it faster and more accurate.

What if the customer is already slipping?

Lead with a conversation about the business. Capital may or may not be the right answer.

Does the pattern differ by country?

Holiday dates, tax calendars and banking days differ, so read the actual dates for each customer instead of assuming a calendar.
