As a founder, you’re constantly making trade-offs—especially when it comes to time. Between building product, managing a team, and preparing for your next raise, bookkeeping often falls to the bottom of your to-do list. But messy or late books can have real consequences when it’s time to make decisions or face the IRS.

That’s where outsourced bookkeeping comes in.

Instead of hiring a full-time bookkeeper—or doing it yourself—outsourcing gives you access to professional support that keeps your finances organized, accurate, and investor-ready, without adding to your overhead.

What is outsourced bookkeeping?

Outsourced bookkeeping is when you hire an external partner or service provider to manage your startup’s financial records—monthly reconciliations, categorization of expenses, P&L reports, and more—without having to bring someone in-house.

These services are typically provided by accounting firms or startup-focused bookkeeping companies. Some offer software integrations and dashboards, while others combine tools with human experts. The key difference is that you're not building or managing a finance department yourself.

Outsourced bookkeeping is designed to be:

  • Flexible: You can start small and scale support as you grow
  • Specialized: Providers often focus on startups, understanding your context and needs
  • Cost-effective: You avoid the salary, benefits, and onboarding costs of a full-time hire

What does an outsourced bookkeeper actually do?

A good outsourced bookkeeping service will handle the essential tasks needed to keep your startup’s finances in shape:

Bank and credit card reconciliations

Your outsourced bookkeeper will carefully review and match every transaction from your bank and credit card statements with your general ledger. This ensures that your financial records are accurate, complete, and audit-ready month after month.

Categorization of expenses and income

Rather than leaving your books cluttered with generic labels or uncategorized transactions, a bookkeeper will classify every expense and source of income based on how your business operates. This level of detail helps with budgeting, financial analysis, and tax deductions.

Monthly financial statements

You’ll receive professional-grade reports, including your profit and loss statement (P&L), balance sheet, and sometimes cash flow statement. These documents are essential for understanding your financial health and for preparing reports for investors or internal planning.

Chart of accounts management

A clean, well-structured chart of accounts is foundational to good bookkeeping. Your provider will ensure your categories are tailored to your startup's model (SaaS, marketplace, services, etc.), allowing for more insightful analysis and better investor reporting.

Support during tax season

When it’s time to file, your outsourced team ensures all your records are up to date and ready for your CPA or tax advisor. This minimizes delays, helps you avoid penalties, and makes the entire filing process less stressful.

In some cases, services also include:

  • Revenue recognition support (for SaaS)
  • Bill pay or payroll add-ons
  • Cash flow dashboards or AI-generated insights

At Lazo, our bookkeeping team works in sync with tax advisors and financial consultants—so your numbers are always ready for the next investor meeting or IRS deadline.

When should a startup outsource bookkeeping?

If you’re a founder managing your books manually or letting them pile up until tax season, it’s probably time to consider outsourcing. Here are several common triggers that indicate it might be time to bring in expert support:

1. You're spending too much time in spreadsheets

If updating QuickBooks or tracking receipts is eating into your product or fundraising work, your time is better spent elsewhere. Founders should be focusing on growth—not reconciling Stripe payouts.

2. You’re preparing to raise capital

Investors expect accurate, clean financials. If you’re not ready to share updated financial statements, projections, or burn rate data, you may lose credibility fast.

3. You missed (or almost missed) a tax deadline

Late books delay your filings. That can mean penalties, interest, or just a lot of unnecessary stress during tax season.

4. Your finances are getting more complex

Maybe you just started charging customers. Or expanded to another state. Or opened a new bank account. The more complexity, the greater the risk of errors. And the harder it becomes to maintain accuracy without help.

5. You don’t have a finance team

You may not need a CFO yet—but that doesn’t mean you should wing your books. Outsourcing gives you the benefits of a finance function without the cost of building one.

6. You need financial clarity for decision-making

If you’re unsure how much runway you have left, what your monthly burn is, or whether your pricing model is profitable, you’re operating in the dark. Bookkeeping is the first step to having visibility and control over your startup’s financial health.

7. You’re working with a tax advisor or CPA

Many tax professionals require clean, updated books to deliver their best work. Outsourcing bookkeeping ensures that your numbers are ready when tax season arrives—or when a new opportunity comes up.

8. You're growing—and things are slipping through the cracks

From team reimbursements to SaaS subscriptions and investor deposits, every transaction needs to be tracked. If you're finding surprises in your bank statements or losing visibility, it's time to bring in support.

Benefits of outsourcing your startup bookkeeping

Outsourcing isn’t just about offloading busywork. When done right, it creates operational clarity that gives you space to grow.

Here’s what you gain:

  • Accuracy and consistency: Professional bookkeepers ensure your records are clean, complete, and audit-ready.
  • Investor-readiness: Well-maintained books speed up due diligence and increase trust.
  • Stress-free tax season: Everything’s organized, categorized, and ready for your CPA.
  • Cash flow visibility: Monthly reports let you see how much you’re spending, earning, and burning.
  • Founder focus: You stay focused on building—while experts handle the back office.

Some startups wait too long to outsource, trying to DIY until the numbers get messy. But cleaning up books is harder (and more expensive) than keeping them up to date from the start.

How much does outsourced bookkeeping cost?

Costs vary based on the provider and the complexity of your business, but here’s a general range:

  • Early-stage startup with simple needs: $200–$500/month
  • Growing startup with more transactions: $500–$1,000/month
  • More complex operations (multiple entities, revenue streams): $1,000+/month

Some providers charge a flat monthly fee, while others bill hourly or offer tiered plans. Lazo’s bookkeeping plans are designed for startups and integrate with tax prep and financial planning support—so you don’t have to manage multiple providers.

If your books are behind, you might need a one-time cleanup to get started.

How to choose the right outsourced bookkeeping service

Look for a partner that understands startups—not just small businesses in general. Here are a few things to look for:

  • Startup experience: Do they work with funded and bootstrapped companies?
  • Tech stack compatibility: Can they work with your existing tools (like QuickBooks, Stripe, or Gusto)?
  • Financial reporting: Do they send monthly reports you can actually use?
  • Tax and compliance alignment: Can they work with your tax team or handle filings directly?
  • Scalability: Will their service evolve as you grow?

At Lazo, we combine human expertise with intelligent tools to keep your books investor-ready, tax-compliant, and aligned with your financial roadmap.
