You don't need QuickBooks Online or Zoho Books to use the LedgerSync Rules Engine. Go to Rules Engine > Manual, open Settings > Initial Setup > Manual Setup, pick a client and upload an Excel file. The standard Template holds vendors and categories without GL codes, and the ACS Template has a GL Code column. Bank accounts are not part of either template.
There are two download buttons for these templates. Each gives you a different Excel file.
You only need the template that fits your data. You can upload a chart of accounts with GL Code and GL Description filled in and Vendor Name left blank.
Each row of the ACS template is read on its own terms. A vendor name on the same row as a GL code is added to the client's vendor list, but it is not linked to that GL code.
The ACS template keeps one row per GL Code. A row whose GL Code is already on an earlier row is left out, together with the vendor name on that row, and a warning in the upload results says how many rows were left out and names the repeated GL Codes (up to 10 of them, then how many more).
If the client already has uploaded data, LedgerSync asks whether to remove it first (Delete and Upload) or add to it (Keep and Upload).
The uploaded data also appears under Settings > Client Settings as Manual Categories and Manual Vendors.
Through a rule and a Global Category. The two templates above do not link a vendor to a GL code. Create a Global Rule that assigns the vendor's transactions to a Global Category, then map that Global Category to the client's GL account in Settings > Global Settings > Global Categories.
When you upload with the ACS template, LedgerSync also adds each GL account to your firm's Global Categories (or reuses one with the same name) and links the client's account to it. Check those mappings in Global Categories before you rely on them.
If you're on Accounting CS, use this same page: the ACS Template, the ACS Chart of Accounts upload scope and the ACS export option are the Accounting CS versions.
