DOSP Explained: How GM's Daily Order Submission Process Works (and How to Get It Right Every Cycle)

If you're a GM dealer, you already know DOSP shows up in your workflow every single week. But a surprising number of dealerships — even ones that have been ordering vehicles for years — don't have a clear picture of how the process actually works behind the scenes, or how much is riding on getting it right.

Here's a plain-language breakdown of DOSP, why it matters more than most dealers realize, and where the most common (and costly) mistakes happen.

What the Daily Order Submission Process Actually Is

DOSP stands for Daily Order Submission Process. It's the system General Motors uses to let dealers submit and adjust new vehicle orders on an ongoing basis, rather than through one big order window. Instead of placing orders once and waiting, dealers work within recurring cycles — submitting, editing, and finalizing orders as allocation, constraints, and market data shift in real time.

Each DOSP cycle typically closes on a set day each week (commonly Friday or Monday), which means the order you submit today isn't locked in — it can still be adjusted right up until that cutoff. That flexibility is valuable, but it also means the process rewards dealers who stay engaged with it every single cycle, not just occasionally.

Why DOSP Matters More Than It Looks Like It Does

On the surface, DOSP just looks like a scheduling system. In practice, it's one of the biggest levers a dealership has over its own future inventory — and, over time, its allocation.

A few reasons this matters:

• Allocation isn't static. GM adjusts a dealer's allocation based on sales performance and how effectively that dealer manages its ordering. Dealers who consistently submit strong, data-backed orders tend to see their allocation grow. Dealers who submit late, incomplete, or poorly matched orders tend to see it shrink.

• Market data changes weekly. What sold fast last month might be sitting on someone else's lot this month. DOSP is designed around this — but only if someone is actually pulling and acting on current data every cycle.

• Constraints move. Paint colors, trims, and specific configurations go in and out of constraint status regularly. An order that was fully open two weeks ago might hit a wall today if nobody caught the change in time.

In other words, DOSP isn't a formality to get through — it's an ongoing decision-making process, and the dealers who treat it that way tend to come out ahead.

Where Most Dealers Get DOSP Wrong

After years of managing this process for dealerships across the country, a few patterns show up again and again:

1. Ordering reactively instead of using current market data. It's tempting to order "what usually sells" or repeat last month's order with small tweaks. But GM's own sales data, combined with a dealer's specific market trends, often tells a different story week to week. Orders built without checking current data tend to result in inventory that turns slower than it should.

2. Missing the cadence. Because DOSP cycles happen frequently, it's easy for order submission to become an afterthought squeezed in at the last minute before Friday's cutoff. Rushed orders are where mistakes creep in — wrong configurations, missed constraint changes, or orders that don't reflect the latest allocation numbers.

3. Not accounting for Consensus. DOSP doesn't operate in isolation — it's tied closely to Consensus, the forecasting numbers submitted (often twice a month) that influence allocation over time. Dealers who manage DOSP well but ignore Consensus, or vice versa, end up working against themselves without realizing it.

4. No one dedicated to watching it closely. At a lot of dealerships, DOSP gets handled by whoever has time that week — a sales manager, a GM, sometimes the owner. Understandably, it's rarely anyone's full-time focus. But a process that runs every week, is tied directly to allocation, and requires constant data monitoring is hard to do well as a side task.

What "Doing DOSP Right" Actually Looks Like

A strong DOSP cycle typically includes:

• Reviewing current market and sales data before building the order — not defaulting to habit

• Checking constraints and paint/trim availability before finalizing, not after submission

• Submitting early enough in the cycle to leave room for adjustments

• Keeping DOSP decisions aligned with what's been submitted in Consensus

• Communicating with the team so everyone's aware of what's been ordered and why

Done consistently, this is what protects — and eventually grows — a dealership's allocation over time. Done inconsistently, it's usually the quiet reason allocation stalls without an obvious cause.

The Bottom Line

DOSP is one of those processes that's easy to underestimate because it happens in the background, week after week. But it's also one of the clearest places where consistent, data-driven attention pays off in allocation growth — and where neglect quietly costs dealers inventory they didn't even realize they were losing.

If your team is stretched thin and DOSP has become something that gets handled rather than optimized, that's exactly the gap Inventory Specialists exists to close. We manage DOSP, Consensus, and allocation strategy full-time for GM dealers nationwide, so nothing falls through the cracks between cycles.
