File Import Tool: Complete Mapping Guide

Master ClientSynq's file import tool to quickly import invoices, payments, and other transactions from spreadsheets into QuickBooks Online.

Overview

The File Import Tool lets you:

• Import invoices in bulk from CSV or Excel

• Maintain data accuracy

Time savings: Import 100 invoices in 5 minutes vs 2+ hours of manual entry!

---

Before You Import

Prerequisites

✅ QuickBooks must be connected to ClientSynq
✅ Customers must exist in QuickBooks (or you'll create them during import)
✅ Products/Services must exist in QuickBooks
✅ Clean data - No typos, extra spaces, or formatting issues

Prepare Your File

Supported formats:

• CSV (.csv)
• Excel (.xlsx, .xls)

File structure:

• First row = Column headers
• Each subsequent row = One transaction (or one line item)

Character encoding: UTF-8 (for special characters)

---

Step-by-Step Import Process

Step 1: Access Import Tool

1. Log in to ClientSynq
2. Go to Clients or Transactions
3. Click Import button
4. Select Import from File

Step 2: Upload Your File

1. Click Choose File or drag & drop
2. Select your CSV or Excel file
3. Click Upload
4. Wait for file to process (usually 5-15 seconds)

Step 3: Map Your Columns

This is the most important step!

The import tool shows:

• Your file columns (left side)
• QuickBooks fields (dropdown on right)

Map each column to the correct QuickBooks field:

Required mappings (must be mapped):

• Customer
• Invoice Date (or Transaction Date)
• Amount (or Item + Quantity + Rate)

Optional mappings (highly recommended):

• Item/Product/Service
• Description/Memo
• Class
• Location
• Invoice Number (if you have specific numbers)
• Due Date

Example mapping:

Your Column Name          →    QuickBooks Field
-------------------------------------------------
"Client"                  →    Customer
"Date"                    →    Invoice Date
"Service Provided"        →    Item/Product
"Total"                   →    Amount
"Dept"                    →    Class
"Office"                  →    Location
"Notes"                   →    Description

Step 4: Review & Validate

After mapping, the tool validates your data:

Green checkmarks ✅: Data looks good
Yellow warnings ⚠️: Potential issues (review but can proceed)
Red errors ❌: Must fix before importing

Common warnings:

• Customer not found (will create new customer)
• Item not found (may need to add to QuickBooks first)
• Date format unclear
• Amount seems unusual (very high or low)

Step 5: Choose Import Options

Create new customers?

• ✅ Yes: Import tool creates customers that don't exist in QuickBooks
• ❌ No: Skip rows with unknown customers

Send to clients?

• ✅ Yes: Email invoices to clients after import
• ❌ No: Create as drafts (you'll send manually later)

Duplicate handling:

• Skip duplicates (if invoice # already exists)
• Import anyway (creates duplicate)
• Update existing (replaces if invoice # matches)

Step 6: Import!

1. Click Import Transactions
2. Wait for processing (30 seconds - 5 minutes depending on size)
3. Review import summary:
   • ✅ Imported: 95 invoices
   • ⚠️ Warnings: 3 invoices (review)
   • ❌ Failed: 2 invoices (see errors)

Step 7: Verify in QuickBooks

1. Go to QuickBooks Online
2. Check Transactions → Sales → Invoices
3. Spot-check a few imported invoices
4. Make sure amounts, customers, classes, locations are correct

Understanding Column Mapping

Required Fields

1. Customer

What it is: The QuickBooks customer who gets the invoice

Mapping options:

• "Customer"
• "Client"
• "Client Name"
• "Company"

Important:

• Name must match QuickBooks exactly (spelling, spacing, punctuation)
• "ABC Corp" ≠ "ABC Corp." ≠ "ABC Corporation"

Tips:

• Export customers from QuickBooks first
• Use exact names in your import file
• Or allow import tool to create new customers

2. Invoice Date (or Transaction Date)

What it is: When the invoice was created

Mapping options:

• "Invoice Date"
• "Date"
• "Transaction Date"

Supported formats:

• MM/DD/YYYY (US format): 01/15/2025
• YYYY-MM-DD (ISO format): 2025-01-15
• DD/MM/YYYY (if tool is configured for it)

Tips:

• Be consistent with format throughout file
• Avoid text like "Jan 15" (may not parse correctly)
• Use Excel date formatting if in Excel

3. Amount

What it is: Total invoice amount

Option A: Single Amount Column

• Use when you have one line item per invoice
• Column name: "Amount", "Total", "Invoice Amount"

Option B: Item-based (Quantity × Rate)

• More detailed
• Requires: Item/Product + Quantity + Rate columns
• Tool calculates: Amount = Quantity × Rate

Tips:

• Don't include $ or commas: Use 1000, not $1,000
• Decimals are fine: 1500.50
• Negative amounts for credits: -100

---

Optional But Recommended Fields

4. Item / Product / Service

What it is: The QuickBooks Product/Service being billed

Why map it:

• Proper revenue categorization
• Detailed reports
• Inventory tracking (if applicable)

Column names:

• "Item"
• "Product"
• "Service"
• "Service Type"

Must match: QuickBooks Product/Service name exactly

If not mapped: Tool may create generic line item or use default

5. Description / Memo

What it is: Additional details about the transaction

Column names:

• "Description"
• "Memo"
• "Notes"
• "Details"

Appears:

• On invoice (client can see)

What it is: QuickBooks Class for categorization (Department, Project, etc.)

Column names:

• "Class"
• "Department"
• "Project"
• "Cost Center"

Important:

• Must match QuickBooks Class name exactly
• Understand if you're using transaction-level or line-item class tracking
  • See: Class Tracking Guide

If using line-item class tracking:

• Each line item can have its own class

7. Location

What it is: QuickBooks Location (physical location, office, store)

Column names:

• "Location"
• "Store"
• "Office"
• "Branch"

Important:

Example:

• Item: Consulting Services
• Quantity: 10
• Rate: 200
• Total: $2,000

11. Rate / Price

What it is: Price per unit

Column names:

• "Rate"
• "Price"
• "Unit Price"

Used with: Quantity × Rate = Amount

Import Scenarios & Examples

Scenario 1: Simple Invoice Import (Flat Amounts)

Use case: You have total invoice amounts, one line item per invoice

Your file:

Customer,Date,Amount,Description
ABC Corp,01/15/2025,1000,January Consulting
XYZ Inc,01/16/2025,2500,Website Development
DEF LLC,01/17/2025,500,Monthly Retainer

Mapping:

• "Customer" → Customer
• "Date" → Invoice Date
• "Amount" → Amount
• "Description" → Description

Result: 3 invoices created with single line items

---

Scenario 2: Multi-Line Invoice Import

Use case: Each invoice has multiple line items (products/services)

Your file:

Customer,Date,Item,Quantity,Rate,Description
ABC Corp,01/15/2025,Consulting,10,200,Strategy Session
ABC Corp,01/15/2025,Travel,1,150,Client Visit
XYZ Inc,01/16/2025,Design,20,100,Website Design

  • Line 1: Training $1,200 (Class: Marketing)

Note: Location is transaction-level (one per invoice), but Class can be line-level

---

Scenario 5: Payment Import

Use case: Import payments received outside of ClientSynq

Your file:

Customer,Date,Amount,Payment Method,Reference,Invoice Number
ABC Corp,01/20/2025,1000,Check,Check #5432,INV-001

Common Mapping Issues & Solutions

Issue 1: Customer Not Found

Error: "Customer 'ABC Corp' not found in QuickBooks"

Causes:

• Spelling doesn't match exactly
• Customer doesn't exist yet

Solutions:

1. Fix spelling in import file

   • Export customer list from QuickBooks
   • Copy exact names
   • Update your import file

2. Allow tool to create customers

   • Check "Create new customers if not found"
   • Import tool creates them automatically

3. Create customers in QuickBooks first

   • Add missing customers to QuickBooks
   • Sync ClientSynq with QuickBooks
   • Try import again

Issue 2: Item/Product Not Found

Error: "Product 'Consulting Services' not found"

Solutions:

1. Create items in QuickBooks first

   • Settings → Products and Services → New
   • Add all items/services you're importing
   • Sync ClientSynq
   • Try again

2. Use generic item (not recommended)

   • Map to a default "Service" item
   • Less detailed tracking

3. Skip item mapping

   • Import with just amounts (no item detail)
   • Manually add items later

Issue 3: Date Format Not Recognized

Error: "Invalid date format in row 5"

Causes:

• Inconsistent date formats in file
• Unsupported format

Solutions:

1. Standardize format:

   • Use MM/DD/YYYY throughout (US standard)
   • Or YYYY-MM-DD (ISO standard)
   • Be consistent!

2. Excel date issues:

   • Format cells as "Date"
   • Don't use text dates like "Jan 15"
   • Save as CSV (not Excel) before upload

3. Check for typos:

   • "01/32/2025" is invalid (no 32nd day)
   • "13/15/2025" is invalid (no 13th month in MM/DD format)

Issue 4: Amount Not Calculating

Error: "Amount missing or invalid"

Causes:

• $ or commas in amount: "$1,000" (should be 1000)
• Text in amount field: "One thousand"
• Blank cells

Solutions:

1. Remove formatting:

   • No $ symbols
   • No commas
   • Just numbers: 1000, not $1,000.00

2. Excel formula to clean:

   =VALUE(SUBSTITUTE(SUBSTITUTE(A2,"$",""),",",""))
   

3. Check for blanks:

   • Every row needs an amount
   • Use Excel's "Find & Replace" to find empty cells

Issue 5: Multiple Invoices Not Grouping

Problem: Each row becomes a separate invoice instead of grouping

Expected: Rows with same Customer + Date = one multi-line invoice
Actual: Each row = separate invoice

Causes:

• Customer name not identical (extra space, different spelling)
• Dates don't match exactly
• Time included in date (2025-01-15 10:00 AM ≠ 2025-01-15 2:00 PM)

Solutions:

1. Ensure exact customer match:

   =TRIM(A2)  // Remove extra spaces
   

2. Standardize dates:

   • Format all dates the same way
   • Remove time component if present

3. Verify in preview:

   • Import tool shows preview before final import
   • Check if grouping is correct

Best Practices

1. Start Small

Test import with 3-5 transactions first:

• Verify mapping is correct
• Check results in QuickBooks
• Then import full file

Why: Easier to fix 5 bad records than 500!

2. Keep a Template

Create a perfect import file:

• All columns properly named
• Sample data in correct format
• Save as template

Reuse for future imports:

• Copy/paste new data into template
• Columns already mapped correctly
• Faster imports every time

3. Clean Your Data First

Before importing:

• ✅ Remove extra spaces: =TRIM(A2)
• ✅ Check for duplicates
• ✅ Validate dates are dates (not text)
• ✅ Remove $ and commas from amounts
• ✅ Verify customer names match QuickBooks

Tool: Use Excel's "Data" → "Remove Duplicates" and "Text to Columns"

4. Export Reference Data from QuickBooks

Before importing, export:

• Customer list
• Products/Services list
• Class list (if using)
• Location list (if using)

Use as reference when building import file

5. Document Your Mapping

Create a mapping guide:

Our Spreadsheet Column    →    QuickBooks Field
------------------------------------------------
"Client"                  →    Customer
"Billing Date"            →    Invoice Date
"Service Description"     →    Item/Product
"Fee"                     →    Amount
"Practice Area"           →    Class
"Office Location"         →    Location

Share with team so everyone uses the same format

6. Handle Errors Gracefully

If import fails:

• Download error report (if available)
• Fix errors in original file
• Re-import (tool usually skips successful rows)

Don't:

• Panic and try to fix manually in QuickBooks
• Import multiple times without fixing errors
• Ignore warnings (they often become errors)

---

Advanced Tips

Importing Negative Amounts (Credits)

Use case: Credit memos, refunds

How: Use negative amount

Customer,Date,Amount,Description
ABC Corp,01/15/2025,-500,Refund for returned product

Result: Credit memo for $500

Importing with Tax

Column: "Sales Tax"

Mapping: "Sales Tax" → Sales Tax

Note: Tax rate must exist in QuickBooks

Example:

Customer,Date,Amount,Sales Tax,Total
ABC Corp,01/15/2025,1000,80,1080

Importing with Discounts

Column: "Discount"

Mapping: "Discount" → Discount

Example:

Customer,Date,Amount,Discount,Total
ABC Corp,01/15/2025,1000,100,900

Result: Invoice shows $1,000 with $100 discount = $900 due

---

Troubleshooting

Import is Slow

If importing 100+ records:

• Be patient (can take 5-10 minutes)
• Don't refresh page (will cancel import)
• Check internet connection

Ways to speed up:

• Split into smaller files (50 records each)
• Import during off-peak hours
• Ensure stable internet connection

Import Keeps Failing

Check:

1. File size (under 10 MB recommended)
2. Number of rows (under 1,000 recommended)
3. Special characters (avoid if possible)
4. Excel formulas (save as CSV to remove formulas)

Solution: Break into smaller chunks

Duplicate Transactions

Problem: Imported twice accidentally

Solution:

1. Go to QuickBooks
2. Find duplicate invoices (same customer, date, amount)
3. Delete duplicates
4. Or use "Update existing" option in import tool (replaces, doesn't duplicate)
