What is Finance? If you already have Accounting, why do you still need Finance?

From the previous three articles, you’ve learned:

•       Accounting is a recording system - from Ms. Bay’s old land notebook to MISA software (Article 01)

•       The three financial statements tell three different stories about a business (Article 02)

•       The Balance Sheet Approach helps you “inspect” your numbers and self-audit (Article 03)

So now you have accurate data. You know how much profit you made, what you own, what you owe, and where the money went. But there’s a bigger question that accounting alone cannot answer: “The numbers are correct - now what do we do with them?”

That’s when Finance steps in.

Think about driving a car:

(*) GPS: Global Positioning System — a satellite network developed by the U.S. Department of Defense to determine precise location, speed, and time 24/7 in all weather conditions. The system uses signals from at least 3–4 satellites to calculate coordinates (longitude, latitude, altitude) worldwide, and is widely used in smartphones, cars, aircraft, and ships.

Let’s return to Minh’s story. After one year in business, Minh knows how to read financial statements and how to “inspect” them using the BSA method. But now he faces questions that accounting numbers alone cannot answer:

Question 1: “Should I borrow 500 million VND to stock up for the sales season?”

Minh wants to purchase a large inventory batch to capitalize on the upcoming sales season. He needs 500 million VND. His bank account has only 100 million VND.

Accounting says: “You’re making 15 million VND per month. Your current debt is 200 million VND.” → Information, but no answer.

Finance says: “Borrowing 500 million at 12% per year = about 5 million/month in interest. Sales season could triple revenue. With a 15% margin, 1.5 billion in revenue → 225 million gross profit. After cost of goods, interest, and ads → net profit ≈ 60 million.
ROI = 12% in one month. Worth borrowing — but inventory must be sold within 45 days.”

Question 2: “Should I open TikTok Shop or focus on Shopee?”

Accounting says: “Shopee generates 300 million VND/month. TikTok Shop has no revenue yet.”

Finance says: “Shopee margin is 8%. TikTok Shop could reach 12% due to lower platform fees. Channel setup cost ≈ 30 million. If it reaches 100 million revenue within the first 3 months → break-even.
Plus: risk diversification — not depending 100% on one platform.”

Question 3: “When should I hire 3 more employees?”

Accounting says: “Current personnel expenses are 25 million VND per month.”

Finance says: “3 new hires = +20 million/month. Break-even if they generate 150 additional orders/month (profit ≈ 130k/order). Currently, 2 staff handle 200 orders/day and are overloaded. Adding staff increases capacity to 350 orders/day → enough to cover costs. Hire 2 first. Hire the 3rd once orders exceed 300/day.”

Question 4: “What is my business actually worth?”

Accounting says: “Owner’s equity is 270 million VND.”

Finance says: “270 million is book value. But the shop is growing 20% per month, operations are stable, and there’s a 50,000-customer database. Real value could be 3–5x book value. If raising capital or selling, valuation could reach 1–1.5 billion VND.”

Question 5: “Can we survive if revenue drops 50%?”

Accounting says: “Cash on hand: 50 million. Fixed costs: 40 million/month.”

Finance says: “Revenue down 50% → negative cash flow of 25 million/month. 50 million cash = 2 months of survival. You need a 3-month safety buffer (120 million) or reduce fixed costs to 25 million.”

Hai lĩnh vực này không tách rời nhau. Chúng tạo thành một vòng lặp liên tục:

The closed loop: 

Accounting records → Finance analyzes → Owner decides → Action → Results recorded again by Accounting. Remove any link, and the loop breaks.

Most small business owners in Vietnam have accounting (simple or outsourced). But almost none truly have finance. Why?

Hiring tax services and thinking that’s enough

This is the #1 misconception. A tax service provider files your tax returns. They don’t analyze cash flow, don’t build forecasts, and don’t help you make strategic decisions.It’s like going for an annual health checkup - but no one monitors your daily health.

Making decisions based on intuition

“Sales are good, so let’s import more inventory.” “I know this person, so I’ll let them buy on credit.” “Our competitor increased ad spending, so we should too.” All of these are decisions made without data-backed financial analysis.

No forecasting, no scenarios

Unprepared when sales season arrives → no cash to restock at the most critical moment. Unprepared when revenue drops → no idea which costs to cut. Unprepared when platforms change policies → no alternative sales channels.

No numbers to talk to banks or investors

When applying for a loan, the bank asks: 12-month revenue forecast? Repayment plan? Cash flow analysis? Without these, you get rejected. When raising capital, investors ask: Unit economics? CAC? LTV? If you can’t answer, you lose the opportunity. 

The common mistake

Many e-commerce shop owners are excellent at selling - but they never truly scale because they lack financial thinking. Họ vay không đúng lúc (hoặc không nghĩ đến vay), nhập không đúng lượng, tuyển không đúng thời điểm. Tất cả vì không có ai làm “tài chính” cho họ.

The answer: both. But at each stage, the focus is different:

If you’re in stage 1: reread Articles 01 and 02 — that’s enough to get started.
If you’re in stage 2: Article 03 (BSA) will change how you see your numbers.
And if you’re in stage 3: you need a financial partner, not just a bookkeeper.

If you’ve read this far, you’ve gone through a journey that very few small business owners in Vietnam have ever taken:

If you’ve read this far and realize you’re missing one (or both) links — that’s completely normal.

Most SME business owners and e-commerce sellers in Vietnam are in the same situation: they have a tax service provider, but no one helping them understand the numbers to make decisions. Sliner doesn’t just handle tax accounting.
