How long should a referrer be silent before I worry?

Two full months with no orders, when they previously ordered consistently, is the point where recovery gets materially harder. A single quiet month is usually just timing.

Why not just look at total revenue?

Because it hides this completely. A referrer worth a lakh a month can stop entirely and the total barely moves if two others grew slightly. The loss shows up as a missing line, not a falling number.

What if the doctor simply had fewer patients?

That is the useful conversation. The signal tells you where to ask; it does not tell you why. A call that opens with a specific fact lands better than one that opens with a guess.

How to spot a referring doctor who has quietly stopped

Nobody sends a letter. The orders just stop, and you notice about two quarters later — usually when someone asks why the month looks soft.

This is the single most expensive blind spot in a lab's numbers, and it is invisible in every report most labs actually look at. Here is why, and what to look at instead.

Why your revenue total will not tell you

Suppose a referrer worth ₹1.1 lakh a month stops entirely. If two other accounts each grew ₹50,000 that month, your total moved by ₹10,000 and nothing looks wrong. The loss did not show up as a falling number — it showed up as a missing line, and totals do not have missing lines.

By the time it is visible in the total, the referrer has had a working relationship with someone else for months. Recovery after a second silent month is materially harder.

What to look at instead

The question is not "how much did we bill" but "who used to bill and does not any more". Concretely, for each account or referring doctor:

When was their last order?
Were they consistent before that, or always sporadic?
What was their monthly run rate when they were active?

A referrer who ordered every week for a year and has ordered nothing for eighty days is a different situation from one who orders twice a year. Both have "no orders this month". Only one is a problem.

Do this in a spreadsheet, if you like. Pivot your Day Wise Ordering export by account and month, sort by the last month with any value, and look at the accounts whose recent columns are empty but whose earlier columns are not. It is tedious and it works. The point of a tool is that it does this every time you upload, not that the logic is secret.

Be careful about what the signal means

It tells you where to ask. It does not tell you why. A doctor may have moved practice, gone on leave, had a slow quarter, or started sending elsewhere. Treating the signal as an accusation is how you damage a relationship you were trying to save.

The useful version of the call opens with a specific fact — "we noticed we haven't seen anything since June" — rather than a guess. Specific gets a real answer; vague gets politeness.

What "consistent" should mean

Careful with month-on-month comparisons for accounts that only just started. An account that began two days before the period ended will show enormous growth against nothing, and that is arithmetic, not momentum. A fair comparison needs the account to have been present for a meaningful share of the window on both sides.
