What Depletion Data You Owe Your Suppliers — and Why Sending It Is Worth It

Your suppliers are flying blind. They shipped you product, they're watching their depletions roll in once a month — maybe — and what they're actually getting is a number. Total cases depleted. No account-level detail, no channel breakdown, no velocity by SKU.

They're making brand decisions based on that.

Here's the thing most distribution operations managers don't spend much time thinking about: how you share depletion data is a supplier relationship management decision, not just an IT task. The distributors who treat it that way consistently get better support, better programming dollars, and earlier access to allocated product. The ones who treat it as a reporting burden get managed accordingly.

What You're Actually Required to Send

Most supplier agreements specify monthly depletion reporting — total cases sold, by SKU, for the period. That's the floor. Most distributors meet it. Some barely meet it. A few send a spreadsheet that looks like it was generated in 2009 and calls it done.

What the agreement says and what's actually useful are different things. A supplier sitting in Napa or Mendoza doesn't need to know you sold 340 cases of their Cabernet last month. They need to know where it went — on-premise versus off-premise, which retail accounts are moving it, whether the new restaurant placement is actually turning, and whether the velocity is trending up or flattening out.

Meeting the contractual minimum is not the same as being a useful distribution partner.

What Good Depletion Reporting Looks Like

The distributors that suppliers genuinely want to work with are sending account-level depletion data — specific accounts, specific volumes, broken down by channel. On-premise here, off-premise there, chain versus independent, by period so the supplier can see trend lines.

This isn't complicated to produce. If your route accounting or ERP system is tracking invoices — and it is — you have this data. It's a report configuration, not a data collection problem.

The better distributors are also flagging anomalies in their own commentary: the placement that didn't move, the account that over-indexed, the market event that drove a spike. That context is worth more than the numbers alone, because it tells a supplier's brand manager something they can actually use.

Why the Data Sharing Gap Exists

Most of it comes down to the same few reasons. First, the standard ERP reports don't produce it cleanly, so someone has to build a custom report — and nobody has volunteered for that project. Second, there's a quiet reluctance to share granular account data, a vague sense that knowing where the product goes is somehow strategic leverage the distributor shouldn't give away.

That instinct isn't completely wrong. But the calculus has shifted. Suppliers have more options than they did ten years ago. They're watching direct-to-consumer sales, they're tracking scan data from chain accounts, and they're increasingly sophisticated about which distributors are actually building their brands and which are just moving cases. The distributor who hoards account data while the supplier watches their DTC numbers tick up is not actually protecting anything.

Transparency is harder to imitate than a good spreadsheet.

The Trust Problem It Creates

When depletion data is thin, suppliers fill in the gaps themselves. They make assumptions about sell-through based on their shipment history to you. They look at their national numbers and guess at what's happening in your market. Their brand managers ask your reps questions your reps can't answer, because nobody has pulled the data.

That creates friction. It creates the perception — often accurate — that the distributor isn't investing in the brand. And it affects decisions: which markets get the winery visit, which distributors get the first allocation of a new vintage, which markets the supplier decides to develop more aggressively with programming dollars.

Those decisions add up. A supplier who trusts your data invests in your market. One who doesn't, hedges.

How to Build the Reporting System That Fixes This

The goal is a standing depletion report — delivered on a consistent cadence, by SKU, with account-level detail — that goes out without anyone having to chase it.

Most mid-size distributors can get there in two to three weeks if the ERP work is prioritized. The configuration isn't complicated. The data is already there. What usually needs to happen is someone deciding this is worth doing and holding the project accountable.

Once the report runs automatically, the ongoing cost is a distributor sales manager spending 20 minutes reviewing it before it goes out. That's the whole commitment.

What Happens When You Do This Well

Suppliers notice. They notice because most of their other distributors aren't doing it. A depletion report with account-level detail, consistent formatting, and a short note from your team explaining what's happening in the market — that's a standing meeting waiting to happen.

That meeting is where programming budgets get allocated. Where the winemaker tour gets routed. Where somebody decides your market gets the next limited release.

The distributors who've built this kind of reporting relationship with their key suppliers aren't doing it out of generosity. They're doing it because it works. The supplier's rep shows up better prepared, the brand gets more attention, and the distributor ends up moving more cases — which is the actual goal.

The data you've already got is sitting in your system. Sending it well is just a decision.
