How it works
Drop the file. Map the columns. Done.
- 1
Export your spreadsheet
From Google Sheets, Excel, or whatever tool holds your data today, export to CSV. If your data lives in QuickBooks, Xero, Wave, or HoneyBook, those tools all export to CSV too.
- 2
Drop it into Wrenbase
Upload the file. Wrenbase reads the headers and shows a preview of the first few rows so you can confirm the data looks right.
- 3
Map your columns to Wrenbase fields
Tell Wrenbase which column is the amount, which is the date, which is the client name. The column names you used don't have to match ours.
- 4
Save the mapping for next time
Once you've mapped a file shape, save it as a template. The next time you import from the same source, the mapping is already done, so you just drop the file.
- 5
Review and import
Wrenbase shows you what will be created and flags any duplicates or rows that need a closer look. Confirm, and the data lands in your account.
Common starting points
Where your data lives today.
A Google Sheet
Open the sheet. File → Download → CSV. Drop it into Wrenbase. Same flow for Excel files.
QuickBooks or Xero
Both export your customers, vendors, and invoice history to CSV. Wrenbase imports those exports.
Wave, HoneyBook, FreshBooks
Each has a CSV export for the data you care about. Bring your existing records with you.
Etsy, Amazon, Shopify
Each platform's standard sales or payout report is a CSV. Drop in, map the columns, every row becomes a transaction.
Bank statement
Your bank's CSV download works too. Useful when you need to backfill payments that didn't come through a billing tool.
Phone contacts
If your clients live in your phone, export contacts as a CSV from Google Contacts or iCloud. Bring them into Wrenbase and they're ready for invoicing.
Your file looks different?
Send it to us and we'll figure it out.
The four import types above cover most of what people bring with them. If your data looks different, whether it's a custom export from a tool we haven't seen, a unique column layout, or anything that doesn't map cleanly, email it to us and we'll help you get it in. The point is your history shouldn't start at zero.
Common questions
Quick answers.
- What can I import into Wrenbase?
- Clients, vendors, invoices, and past transactions. If it lives in a spreadsheet or exports to CSV, you can bring it in and pick up where you left off.
- What file format do I need?
- CSV. Export from Google Sheets, Excel, QuickBooks, Xero, Wave, HoneyBook, a bank statement, or your phone contacts, and drop the file in.
- Do my column names have to match Wrenbase's?
- No. You map your columns to Wrenbase fields once, telling it which column is the amount, the date, the client name, and it remembers the mapping so the next import from the same source is one step.
- What happens to duplicates?
- Before anything is created, Wrenbase shows you a preview and flags duplicates or rows that need a closer look. You confirm, then the data lands in your account.
- What if my file doesn't fit the standard types?
- Send it to us. If your export has a custom layout or a shape we haven't seen, email it over and we'll help you get it in. Your history shouldn't start at zero.
- Is there a fee to import?
- No. Bringing your data in is free. You only pay for the operational features you use on top.
