Re-Uploading a Corrected Inventory File: A Safe Review Routine

The first upload taught you something: twelve rows failed, four prices were wrong, and two sold units rode in on the DMS export. You fixed the spreadsheet. The dangerous moment is the second click. Re-uploading a corrected inventory file is how lots accidentally create a second copy of a VIN they already posted, or push a still-dirty column back over a clean one. A safe review routine treats the second upload as a controlled event, not a redo of the first.

This routine is for the person who owns Import: the independent operator on Starter, or the manager on a Dealership team. It follows Fixing Row-Level Import Errors: A Troubleshooting Flow. Troubleshooting gets the cells right. This article gets the re-entry right so inventory, queues, and live listings stay one story.

Decide What the Second File Is Allowed to Contain

Most re-upload damage comes from using the same "full lot" export again without deciding what the second file is for.

Three legitimate second-file shapes

Pick one and label the file accordingly:

1. Repaired rows only. Only the VINs that failed or were wrong. Smallest blast radius. Default choice.
2. Full file, known replace process. Every retail unit, because your weekly rhythm is a complete refresh and you have a rule for duplicates and sold units. Do not use this shape as a panic move.
3. New arrivals only. Auction and wholesale buys that were never in the first file. Do not mix these with repairs unless you enjoy sorting two problems later.

If you cannot say which of the three you are holding, you are not ready to upload.

What must not be in the second file

• VINs already posted that have not changed, unless you have a deliberate update process and will not double-queue them.
• Sold units still sitting in the DMS "active" export.
• Recon units you are not ready to photograph.
• A second copy of a vehicle you already captured from an auction site into inventory.

Capture from auction and wholesale sites is a separate intake path. Re-importing the same VIN from Excel after a capture is a classic duplicate. Check inventory first.

Name the file like an audit artifact

lot-repair-2026-10-30-vins.xlsx tells a future manager more than fixed2.xlsx. Import history stores the upload; your disk should still be able to produce the same bytes. Using import history as an audit trail is the longer treatment of that record. For this routine, the rule is simpler: if history and the folder disagree, stop.

A Safe Review Routine Before You Re-Upload a Corrected Inventory File

Run this as a numbered procedure. It is shorter than cleaning up duplicates after the fact.

1. Freeze posting on affected units

If any of the repaired VINs are in a queue or in posting status, get them out of flight. A re-import while the extension is submitting the old data is how you race yourself. Pause additions to the queue for those stock numbers. Let in-flight work finish or be cleared according to status, then continue.

2. Open inventory and import history side by side

For each VIN in the corrected file, write down the current status:

This table is the review. The upload is just the mechanical step. Inventory statuses explained is the reference if a status is unclear. Sold means do not re-import to "refresh" a listing. Posted means you are updating a record, not creating a second vehicle to post again.

3. Diff the corrected file against the first file

You do not need special software.

• Confirm only intended VINs are present (if this is a repair file).
• Confirm the twelve previously failed rows now have complete VIN, price, mileage, year, make, model.
• Confirm you did not reintroduce the column shift you just fixed.
• Confirm prices are the prices you will honor today, not last week's export.

If the first file had a structural problem, do not append repairs onto a copy of the broken file. Build from the values-only clean sheet.

4. Upload, then immediately reopen history

Read the new import event. Read the row-level error log. The acceptable outcomes are:

• Previously failed rows now import.
• They fail for a new reason you can name and fix.
• Zero surprise VINs appeared.

If a VIN you did not intend imported, you uploaded the wrong sheet. Do not keep posting while you figure it out.

5. Spot-check the vehicles, not just the log

Open a sample of repaired records in inventory:

• Specs match the unit on the lot.
• Status is what you expected (usually draft until you choose otherwise).
• AI title and description, generated from the new specs, get an edit. If the first import had the wrong trim, the first AI draft was wrong too. Do not reuse it from memory; review the new draft.

Then choose photos in the Facebook photo picker if this unit is actually going to post. A corrected price on a listing with the old lead photo of a different truck is only a partial fix.

6. Re-queue on purpose

Add to a personal queue or, on a team, assign to an associate queue only after steps 1–5. Do not assume the vehicle is already in someone's queue from last time. Do not assume it is not. Look. Release stuck claims in the team queue view if a rep still holds the old version.

7. Same-day sold check

If the corrected file was a full lot export, run sold-unit hygiene again. Mark sold and archive anything that sold between export and upload. Re-uploading is a common way a sold car returns to "available" in a dashboard even after the floor knows it is gone.

After the Re-Upload: Prove You Did Not Make a Second Lot

The review is not finished when the log is empty.

Duplicate hunt

Search inventory for the repaired VINs. One record each. If two exist, you now have an operational duplicate even if both are in draft. Resolve to one record before anyone posts. Relisting the same vehicle to "refresh" is a behavior that commonly causes Marketplace problems; do not use re-upload as a refresh button.

Queue hunt

Look at personal queues and the team queue view. A VIN should not sit in two claims. Release and reassign rather than posting twice.

History hunt

You should be able to answer, without guessing:

• Which file created the original bad row.
• Which file corrected it.
• Who uploaded each (on a team, that is the logged-in user).
• Whether the unit is draft, posted, or sold now.

If you cannot answer those, the routine failed even if the cars look right on the lot.

When not to re-upload at all

If only one vehicle was wrong, editing that record in inventory may be faster than a second file. Re-upload is for batches and for source-of-truth spreadsheets. Do not build a habit of Excel as the only way to change a price; also do not let a hundred-row error sit because editing one-by-one felt more careful. Match the tool to the size of the mistake.

How PostToMarket Automates This

Re-uploading a corrected inventory file goes wrong when the second upload has no memory of the first. The safe review routine uses import history, statuses, and queues so the second file cannot silently fork the lot.

• Import history for each upload as a distinct event.
• Row-level error log to confirm repaired rows actually cleared.
• Bulk CSV and Excel import for the corrected file you chose (repair-only vs. full file).
• Statuses (draft, posting, posted, sold, failed) as the source of truth after the file lands.
• Personal queues, manager assignment, and team queue view so a repaired VIN is not claimed twice.
• Mark as sold and archive for units that should never have returned.
• AI copy and photo picker as the post-repair listing pass, because corrected specs deserve a new human review.

Unlimited inventory means the old records are still there until you archive or correct them. That is a feature when you review. It is a hazard if you import blindly.

Practice a Second Upload on the 10-Day Trial

The first import shows whether your export is usable. The second import shows whether your shop can correct itself without doubling the lot. Run both during a trial, on real VINs, before you trust a weekly refresh.

A solo operator can do this on Starter at $59 per month with one login. A store that wants a manager owning Import and reps owning queues uses Dealership at $299 per month for up to 13 logins. Both include unlimited vehicles and the same import history.
