Migration guide

Switching your consignment shop from spreadsheets

A practical, week-by-week plan to move off Excel or Google Sheets without losing a single record — written by someone who ran a 130-consignor shop on a spreadsheet first.

Updated July 8, 2026 · By the Consignloop team — built by a working consignment shop owner

First, credit where it's due

The consignment spreadsheet is a rite of passage. It's free, you built it yourself, and for your first dozens of consignors it genuinely works. If you have 15 consignors and an hour of bookkeeping a week, you may not need anything else yet — bookmark this page and come back when it hurts.

How to know it's time

The spreadsheet doesn't fail loudly. It fails as a slow accumulation of small taxes:

Three or more of those, and the spreadsheet is costing more than software would. (We did the direct feature-by-feature math in Consignloop vs. spreadsheets.)

What you're actually migrating

Good news: far less than you fear. You do not need to re-enter years of history. Three datasets matter:

DatasetWhat to bringWhat to leave archived
ConsignorsName, contact info, each person's splitConsignors inactive for over a year (add them back if they return)
InventoryActive items: description, consignor, price, date receivedItems already sold or returned
BalancesEach consignor's current owed amount, as an opening balanceThe old sale-by-sale ledger — keep the file as your historical record

The week-by-week plan

Before you start: pick the destination

Choose software you've actually tested against your daily workflow — intake, tagging, sale, payout. Our buyer's guide and checklist covers what to look for. Make sure the trial is long enough to complete this whole plan inside it (Consignloop's is 21 days).

Day 1–2: Freeze and clean

  1. Make a dated copy of the workbook. This copy is sacred — it's your audit trail and your rollback plan.
  2. Clean the consignor list: one row per person, consistent name spelling, current phone/email, and — critically — each person's split written explicitly, not remembered.
  3. Clean active inventory: delete sold/returned rows from the working copy, standardize columns (item, consignor, price, date received), fix the "see note" cells.
  4. Compute each consignor's current owed balance and get comfortable with the numbers — this is the moment to settle any ambiguity, while the old system is still authoritative.

Day 3–4: Import and verify

  1. Export consignors and inventory as CSV.
  2. Import into the new system (in Consignloop: consignors first, then the inventory bulk upload, which links items to consignors).
  3. Enter opening balances.
  4. Spot-check 10 consignors end to end: right split, right items, right balance. Then check your totals — item count and total owed should match the spreadsheet to the penny. If they don't, fix it now, not after the first payout.

Week 1–2: Parallel run

  1. The new system becomes the source of truth: every intake, sale, and payout gets recorded there, at the counter, as it happens.
  2. Keep the frozen spreadsheet open in a tab if it comforts you — but stop editing it. Two live systems is how numbers drift.
  3. At the end of week one, run your first payout cycle from the new system and hand consignors the printed statement. This is the moment the switch pays for itself.

Week 3: Cut the cord

  1. Archive the old workbook (read-only, backed up).
  2. Train staff on the three core flows: intake + tag, record sale, record payout. If the software is any good this takes an hour.
  3. Optional but transformative: turn on consignor logins for your chattiest consignors. The "did my stuff sell?" texts stop that week.
The one rule that makes migrations succeed: after the import is verified, never enter new data in the old system again. Every failed migration we've seen died the same way — weeks of "I'll just note it in the spreadsheet for now."

What changes on day one

Do the whole migration inside a free trial

Consignloop's 21-day trial fits this entire plan with a week to spare. Bulk CSV import for inventory, per-consignor splits, and statements from day one. No card required to start.

Frequently asked questions

When should a consignment shop move off spreadsheets?

Common tipping points: 30–50+ active consignors, more than an hour or two a week on split math and reconciliation, a payout dispute you couldn't cleanly prove, hiring your first staff member, or realizing only one person understands the workbook.

Will I lose my history?

No. Import consignors, active inventory, and opening balances; archive the old spreadsheet as your read-only historical record. Years of past sales don't need re-entering.

How long does it take?

An afternoon to clean and export, a day to import and verify, then one to two weeks of parallel running. Most shops complete it inside a free-trial window without closing for a day.

What data do I need to bring over?

Three things: the consignor list with each person's split, active inventory with consignor/price/date received, and each consignor's current owed balance.
