/** |
| 19 |
* Why an importer |
| 20 |
* --------------- |
| 21 |
* Nobody moves two hundred clients and three years of invoices by hand, so |
| 22 |
* without an importer the plugin can only win people who have never invoiced |
| 23 |
* before. Sliced Invoices and Sprout Invoices -- the two plugins ahead of us |
| 24 |
* in the directory -- keep their data as post types on the same WordPress |
| 25 |
* install, which means we can read it directly, with no export step. CSV |
| 26 |
* covers everything else (FreshBooks, Wave, Zoho and spreadsheets). |
| 27 |
* |
| 28 |
* Every importer works the same way: `preview()` counts what it would bring |
| 29 |
* in, `run()` brings it in. Records remember where they came from |
| 30 |
* (`_easy_invoice_import_source` / `_easy_invoice_import_source_id`), so running |
| 31 |
* an import twice adds nothing, and a client that already exists here (matched |
| 32 |
* by email) is reused rather than duplicated. Imported documents keep their |
| 33 |
* original numbers and dates; nothing is renumbered. |
