Comparison
Instica vs Spreadsheets for Scaling Resellers
Spreadsheets are the default starting point for resellers everywhere—Excel on Windows, Google Sheets in a browser, Airtable for the more technical crowd, Notion for the organized. They're free, familiar, and flexible. They also eventually become the main source of operational drag for any seller with a growing catalog. This comparison covers when that threshold happens and what changes when you cross it.

Bottom line
Spreadsheets win at zero cost and maximum flexibility for very small catalogs. Instica wins once you're sourcing regularly, listing on eBay or Discogs, or spending meaningful time maintaining inventory records manually.

Best for Spreadsheets (Excel, Sheets, Airtable)
Sellers with fewer than 20 items who want zero cost and full customization
The four stages of spreadsheet breakdown
Almost every reseller uses spreadsheets in the early stages, and for good reason—they're zero-cost and you can start in minutes. But there are predictable stages at which the cracks appear.
First: the first oversell. You list a jacket on both eBay and Depop, both sell within hours, and you only have one. You look at your spreadsheet, which shows it as active. Now you have to cancel one sale, absorb a negative feedback, and manually update two listings. Cost: time, reputation, and stress.
Second: the photo breakdown. You have 200 items and each one's photos are in a Drive folder organized by date. Someone asks about item 47 from three months ago. Finding the right photos takes ten minutes.
Third: the fee formula problem. You calculated your eBay profits on a 12% fee. eBay updated their rates to 13.25% in some categories. You've been underestimating profit for months, or worse, listing at prices that lose money after fees.
Fourth stage: time cost
The most insidious problem is time. As your catalog grows, listing maintenance—updating prices, tracking sold items, reconciling across channels—starts consuming hours that should go to sourcing. The spreadsheet was always the bottleneck, you just didn't notice until sourcing time dropped.
Airtable and Notion help with data structure but don't solve the fundamental problem: no marketplace integration. You still manually list on eBay, manually check for sales, manually update your database. The tools are more polished but the workflow is the same.
What the transition to Instica looks like
The most common transition path: export your spreadsheet to CSV, contact Instica support for import assistance, and spend a week running both in parallel to verify the import looks right. Most sellers complete the transition in under two weeks.
Once you're in Instica, intake changes first. At your next thrift run, you scan barcodes and take photos from your phone. Items are in your inventory before you get home. Listing on eBay or Discogs takes a few taps from within the same app.
Over the first month, reconciliation time drops. You're not checking multiple places to figure out what sold. The inventory is the single source of truth, and the sync keeps it current.
Frequently asked questions
How do I import my spreadsheet into Instica?
Export your spreadsheet as a CSV file. Contact Instica support at support@instica.com with the file and a description of your column structure. The support team will map your fields to Instica's schema and complete the import. Pro users get priority support for migrations.
What about Airtable — is it better than Google Sheets for resellers?
Airtable offers better data structure (proper field types, linked records, gallery views) than Google Sheets, which helps at medium scale. But both lack the critical reseller feature: marketplace API integration. Neither connects to eBay or Discogs. For pure organization, Airtable is more powerful. For resale operations, Instica covers the full workflow.
Can I keep my spreadsheet as a backup while using Instica?
You can, but maintaining two systems creates data drift within days. Most sellers use their spreadsheet only during a transition period, then archive it once they're confident in Instica. Instica supports full CSV export at any time, so your data is portable if you ever want a spreadsheet snapshot.
