Do I need a bookkeeper or is software enough?

Software is enough while transaction volume is low and the business model is simple. The usual switching points are around 100 transactions a month, holding inventory, operating in multiple currencies, or having employees. Before that, a well-configured software setup and a monthly hour of your own time is genuinely sufficient.

Cash or accrual accounting?

Cash basis records money when it moves and is simpler. Accrual records revenue when earned and expenses when incurred, and gives a truer picture of a business with invoices or inventory. Many small businesses may use cash basis for tax, but the rules depend on your entity, revenue and whether you hold inventory — check the current IRS guidance for your situation.

What records do I have to keep, and for how long?

Keep anything supporting income, deductions or credits on a return — invoices, receipts, bank and card statements, contracts, payroll records. The IRS sets retention periods by circumstance, commonly three years from filing, longer in some cases. Digital copies are acceptable if they are complete and legible.

What is the single most common bookkeeping mistake?

Mixing personal and business spending. It undermines the liability separation the company exists to create, it makes deductions difficult to defend, and it turns a one-hour monthly reconciliation into an archaeological exercise at year end.

Bookkeeping and accounting for founders

Bookkeeping is boring until the week it isn't. Set it up once, properly, and tax season becomes an afternoon instead of a fortnight of reconstructing bank statements.

The short answer

Founder bookkeeping means recording every transaction in a dedicated business account, categorising it consistently, and reconciling monthly. Most small companies can use cash-basis accounting. Software costs $15–$50 a month; outsourced bookkeeping starts around $200 a month and is worth it once transaction volume passes roughly 100 a month.

Nobody starts a company because they want to categorise transactions. But bookkeeping is the substrate everything else sits on: your tax return, your ability to borrow, your ability to raise, and your ability to answer the question "are we actually making money?" without guessing.

Set up once, properly, and it costs an hour a month. Neglect it and it costs a fortnight in April, plus whatever the missed deductions were worth.

The non-negotiable first rule

Business money moves through business accounts. Personal money moves through personal accounts. Nothing crosses without being recorded as a distribution or a contribution.

This is the rule everything else depends on. Mixed accounts make deductions hard to defend, make the first tax return miserable, and — most seriously — weaken the argument that the company is genuinely separate from you, which is the entire point of having formed one.

Cash or accrual

	Cash basis	Accrual basis
Records revenue	When the money arrives	When you earn it
Records expenses	When you pay	When you incur the obligation
Complexity	Low	Higher
Shows true profitability	Poorly if you invoice on terms	Yes
Typical fit	Service businesses paid on receipt	Inventory, invoicing on terms, investors

Cash basis is simpler and suits most early service businesses. Accrual gives a truer picture once you invoice on terms or hold stock, and investors will expect it. Eligibility to use cash basis for tax depends on your entity type, your revenue and whether you carry inventory — check the current IRS rules rather than assuming.

A chart of accounts you won't outgrow immediately

Start deliberately small. The instinct is to create fifty categories; the result is inconsistent coding and reports nobody reads.

Income — one line per genuinely distinct revenue stream, not per customer.
Cost of sales — what you spend to deliver: hosting, payment fees, contractor delivery time, goods.
Operating expenses — software, marketing, professional fees, travel, office.
Payroll — separated from contractors, because they are taxed differently.
Owner's equity — contributions in and distributions out, tracked separately.

The monthly hour

Import or sync transactions from every business account and card.
Categorise anything the software could not, and fix anything it guessed wrong.
Reconcile each account to its closing statement balance. If it does not match, find out why now.
Chase unpaid invoices while the work is recent.
Read the P&L and the cash balance. Two minutes. This is the part with actual value.

When to stop doing it yourself

Situation	What you probably need	Rough cost
Under ~50 transactions/month, one currency	Software and your own hour	$15–$50/mo
100+ transactions, or multi-currency	Bookkeeper, monthly	$200–$600/mo
Inventory, or multiple entities	Bookkeeper plus an accountant at year end	$400–$1,200/mo
Employees on payroll	Payroll provider plus bookkeeper	Add $40–$150/mo
Raising, or planning to sell	Accountant on accrual basis	$1,000+/mo

Bookkeeping

Monthly reconciliation, clean categorisation and financials that are ready for a tax return or a data room — instead of a shoebox and a deadline.

See what's included

Reading the three statements

Profit and loss — revenue minus expenses over a period. Answers "did we make money?"
Balance sheet — what you own and owe at a point in time. Answers "what is the company worth on paper?"
Cash flow — money actually in and out. Answers "can we pay people next month?"

Mistakes that cost real money

Mixing personal and business. Every time.
Recording net Stripe deposits instead of gross revenue and fees.
No receipts. A bank line proves you spent money, not what on. Photograph receipts at the point of spending.
Ignoring foreign exchange. Multi-currency businesses that book everything at today's rate produce numbers that are simply wrong.
Leaving it to year end. Twelve months of uncategorised transactions costs several times what twelve monthly hours would have.
Not tracking owner distributions. For a foreign-owned LLC these are reportable on Form 5472 — see taxes.

Where to go next

Clean books make taxes straightforward and are what lenders and investors ask for first. If you sell physical products, e-commerce covers inventory and landed cost.
