Migration
Switching invoicing apps
Changing invoicing apps usually means retyping your customer list on a Sunday evening. It does not have to. Here is exactly what Invoice Tiger can bring across, what it cannot, and how to move it.
What actually moves
Invoice Tiger imports customers and saved items from a CSV, and invoice history from the formats it has been built to read. What comes across depends far more on what your current app is willing to export than on anything at this end — which is why there is a page per product rather than one promise for all of them.
Comes across
- Customers — name, email, phone, address
- Saved items and services, with their prices
- Invoice history, where the format is one we read
- Your invoice numbering, continued rather than restarted
Does not
- Line items on past invoices
- PDFs of documents you already sent
- Your logo, business details and settings
- Anything the other app will not export
Imported invoice history arrives as read-only records — the number, the dates, the customer and the totals, searchable alongside everything else. They are summaries of what you sent, not documents you can edit or send again, because a summary export does not carry the line items needed to rebuild one. Old invoices stay something you can look up rather than something you can re-issue.
Moving from a specific app
There is a page here only where we have built and tested a real import path, which means this list grows slowly and on purpose. If your app is not on it, the customers-and-items route below still works — anything that exports a CSV can be mapped by hand.
Moving from anything else
Get a CSV of your customers out of your current app — most will produce one, and it is worth asking their support if you cannot find it. In Invoice Tiger, open Settings → Import & Export, choose Import Customers, pick the file, and match its columns to the fields. Saved items and services work the same way. Invoice history is the part that depends on the format, and today only Invoice Simple’s is one we read.
You see the file before it lands
Every import shows a row-by-row preview of what will be created, what is a duplicate of something you already have, and what could not be read. Nothing is written until you confirm it, and a confirmed import is written in one go — all of it or none of it, never half a file.
Columns are mapped, not guessed
Where a file is not one we recognise, you match its columns to fields yourself. If two columns could plausibly be the phone number, Invoice Tiger leaves it unmapped and asks rather than picking one. A silent wrong guess across four hundred customers is far more expensive than a screen of dropdowns.
Importing is free
Every import is available without a subscription. Getting your records in is not the thing we charge for, and an app that charged for it would be telling you something about how it plans to treat you later.
And you can leave the same way
Everything you build up here exports to a file you keep, and the export is not behind the subscription either. We would rather make it easy to come in than hard to go.
Worth doing before you commit to any invoicing app, this one included: run its export on day one, while you have nothing to lose, and look at the file it gives you. Our analysis of 5,443 app reviews found reviewers reporting lost invoices across five apps over seven years, and what a monthly cap does to lumpy work covers the other half of why people start looking.
Bring your customers. Leave the retyping.
Invoice Tiger imports your customers and saved items from a CSV, free and before you subscribe to anything.
