From Spreadsheets to Series A: How to Build Your Startup’s Payment Foundation with QuickBooks Payments

That spreadsheet worked perfectly fine when only a few customers were paying you.

Now an investor has asked for your financials, and you’re digging through rows trying to understand why the invoices do not match what reached the bank. 

That is a stressful place to be when you already have a raise to focus on.

If you want to get ahead of the cleanup, this article is a good place to start. We’ll show you how QuickBooks Payments can turn that scattered payment history into a financial system that is easier to maintain and much easier to share when investors start asking questions.

How QuickBooks Payments Supports a Startup Payment Foundation

By bringing everyday payment activity into the same system as your books, QuickBooks Payments gives startups the tools to get paid and stay organized.

Each invoice and eligible payment contributes to the records behind your reports, so you are not reconstructing the financial story of the startup whenever someone asks for the numbers.

You still need to review and reconcile your accounts, but the ongoing work becomes easier to manage. That gives your accountant cleaner records to work with and helps you respond to investor questions more confidently.

Prerequisites and Setup Requirements

Before setting anything up, make sure you have the right QuickBooks Payments account, enough information to build accurate opening records, and a clear plan for maintaining the books.

Choose the Right QuickBooks Payments Setup

Select a QuickBooks Online plan that includes the reporting and access your startup needs. 

Simple Start already includes core reports such as profit and loss, balance sheet, and cash flow, while higher plans add more detail and functionality.

You will also need to apply separately for QuickBooks Payments, which is subject to eligibility, credit, and approval.

Gather Your Existing Financial Records

Bring more than your customer list and revenue spreadsheet. 

Gather your outstanding invoices, bank statements, business expenses, and records of any money contributed or loaned by founders so QuickBooks Payments starts with a more complete financial picture.

Decide How the Books Will Be Maintained

Work with an accountant to choose between cash and accrual accounting and agree on how often the accounts will be reviewed. 

QuickBooks Payments can display reports using either method, but institutional investors often expect reconciled accrual financials as a startup moves toward a priced round.

Once these pieces are in place, you can move into the main setup with fewer corrections to make later.

How to Build Your Startup's Payment Foundation in QuickBooks Payments

Here’s how to set up your invoicing, payments, and financial reporting in QuickBooks Payments so your startup can maintain accurate records and prepare for future fundraising.

1. Set Up QuickBooks Online and Apply for QuickBooks Payments

Establishing your accounting and payment systems early gives you a consistent starting point and reduces the historical information you may need to import or reconcile later. 

QuickBooks Payments requires a separate application and is subject to eligibility, credit, and approval.

2. Choose an Accounting Method With Your Accountant

QuickBooks Payments lets you set cash or accrual as your default accounting method and change the method shown on individual reports. 

Under accrual accounting, income and expenses are generally recorded when they are earned or incurred, which may happen before payment changes hands.

If customers pay in advance for subscriptions or long-term services, those payments may need to be recorded as deferred revenue until the service is provided. 

QuickBooks Online Advanced supports automatic revenue-recognition schedules, while other plans may require a separate process or help from an accountant.

3. Send Customer Invoices Through QuickBooks Payments With Payments Enabled

This creates a consistent record of what customers owe and allows them to pay eligible invoices online. 

QuickBooks Payments can accept credit cards, debit cards, ACH transfers, PayPal, and Venmo and can categorize the resulting payments in your chart of accounts.

4. Review Automatically Recorded and Matched Payments

QuickBooks Payments can automatically match eligible transactions with downloaded bank transactions, reducing manual data entry. 

Automatic matching may not be available for every account or transaction, so unmatched payments still need to be reviewed manually.

Automatic matching also does not replace regular reconciliation. 

You should still compare QuickBooks Payments with your bank and credit-card statements to identify missing, duplicated, or incorrectly categorized transactions.

5. Review Your Core Reports Every Month

Check your profit and loss statement, balance sheet, statement of cash flows, and accounts receivable reports regularly.

QuickBooks Payments provides these reports, although the exact reports and level of detail available depend on your subscription.

Monthly review helps you identify missing or incorrectly categorized transactions before fundraising begins. 

6. Give Your Accountant Separate Access

Invite your accountant or fractional CFO through QuickBooks Payments instead of sharing your login credentials. Accountant access is available on eligible plans, but plan inclusions can change, so check the current comparison before subscribing.

7. Revisit Your Reporting Before Every Fundraising Milestone

As a startup moves toward institutional funding, investors may request reconciled historical financial statements, burn and runway information, unit economics, and financial projections. 

The exact requirements vary by investor and funding stage, so review your reports and supporting records with an accountant before diligence begins. 

What Going From Spreadsheets to Series A With QuickBooks Payments Should Look Like

Once you’ve followed the steps above, you shouldn’t have to piece together your financial history whenever someone asks for it. 

There should be much less last-minute scrambling through spreadsheets to determine which invoices were paid or why the numbers do not match.

Instead, you’ll have organized records that are easier to review as you prepare for fundraising.

Common Mistakes and Pro Tips

A solid setup still needs to be maintained as your startup grows. Keep these common mistakes and practical tips in mind to protect the accuracy of your records.

Recording Founder Money as Ordinary Revenue

Money founders put into the startup should normally be recorded as an owner contribution or loan, not customer income. 

Categorizing it incorrectly can distort your revenue and leave your balance sheet unclear.

Creating Inconsistent Accounts for Every Transaction

Avoid adding a new account whenever you encounter an unfamiliar expense. 

The account types you select determine where transactions appear in your financial reports, so keep your chart of accounts organized and confirm unusual categories with your accountant.

Lock Each Period After It Has Been Reviewed

Once your accountant has reviewed a month or quarter, use QuickBooks Payments’ closing settings to warn users or restrict changes to older transactions.

You can still track any later changes through the Exceptions to Closing Date report.

Save a Copy of Your Monthly Reports

After completing each monthly review, export and save the final reports for that period. 

This gives you a consistent financial history to reference later instead of rebuilding it when an investor begins diligence.

Final Thoughts

Good luck as you put your startup’s payment foundation in place.
