Stop Manually Entering Timesheets into QuickBooks (There's a Better Way)

The Monday Morning Problem

Monday morning. You have a spreadsheet with 40 rows of time entries from last week. Someone needs them in QuickBooks by end of day so invoices can go out. You open QBO, navigate to Time, and start entering. Row by row. Employee, customer, service item, date, hours, description. Forty times.

If this sounds familiar, you're not alone — and you're probably already suspicious that there's a better way.

What Goes Wrong with Manual Entry

Manual timesheet entry into QuickBooks isn't just slow. It introduces a specific set of errors that are hard to catch:

• Transposition errors in hours. 7.5 becomes 75. 1.25 becomes 12.5. QBO accepts both without complaint.
• Wrong customer selection. If you have "Smith Constructions" and "Smith & Co Constructions" in your customer list, it's easy to pick the wrong one under time pressure. The entry goes in. The invoice goes out. Someone notices months later.
• Missing billable flags. If a row goes in without the billable checkbox ticked, it won't appear on the next invoice run. You may not realise until a client questions why their invoice seems low.
• Duplicate entries. Someone submits last week's timesheet. Someone else didn't realise you'd already entered it. It goes in twice. The invoice doubles up on hours. Awkward conversation with client required.

The Real Cost

The time cost is straightforward to estimate. A 40-row timesheet entered manually takes 20–30 minutes at a minimum, assuming you know what you're doing and don't have to look anything up. For a bookkeeper billing at $80/hour, that's $27–$40 per timesheet in labour. For four clients submitting weekly, that's over $400/month in entry time alone.

The error cost is harder to quantify but potentially larger. A missed billable flag on a 3-hour entry at $150/hour is $450 in unbilled work. A duplicated entry that makes it onto an invoice damages client trust in ways that take longer to repair than the error took to make.

Import as the Solution

Timesheet import tools take the Excel file you already have and push the rows directly into QBO as time activities. No re-entry. No transcription. No selecting from dropdowns forty times.

The approach works because QBO has an API that accepts time entries programmatically — the same records you'd create manually, just created by software instead of a person.

How Time On It Handles It

Here's a concrete example. You receive a timesheet from a site manager: 35 rows, employees listed by first name, customers by shortened project codes. Normally you'd spend the first five minutes just decoding the names before you even start entering.

With Time On It, you start by downloading the import template. The template's dropdowns are built from your actual QBO data — full employee names, full customer names, service items, classes. You paste the data from the manager's file into the template, matching names as you go. That part still takes a few minutes. But then you upload the completed template, and all 35 rows go into QBO at once.

Duplicate detection runs automatically. If three of those rows were already in QBO from a correction the manager submitted earlier, they're skipped — not double-imported. You see exactly what went in, what was skipped, and what had missing fields.

The Status column in the template updates to "Imported" after a successful push. If you upload the same file again by mistake, those rows are skipped.
