Zero-Based Budgeting (ZBB): How to Build Your Saudi Company's Budget From Scratch Instead of Rolling Last Year's Numbers Forward

Zero-based budgeting (ZBB) is a financial planning method that starts every cycle — annual or quarterly — at zero and forces the decision-maker to justify every riyal spent from scratch, instead of copying last year's budget and adding an automatic inflation bump.

It was developed by Peter Pyhrr at Texas Instruments in 1969, and later spread through large consumer companies such as Coca-Cola, Kraft Heinz and P&G after 3G Capital adopted it as a cost-restructuring tool. The core idea: every expense line starts at zero by default and receives no funding until it proves its value for the coming year.

Traditional budgeting asks: 'What did we spend on marketing last year? Five thousand? Make it five and a half this year.' Zero-based budgeting asks: 'How much marketing do we need to hit our 2026 targets? Build the number up from channels, campaigns and expected results — not from history.'

Why does this matter in the Saudi market in 2026? Three pressures make ZBB especially relevant right now: rising labour costs following higher Saudization quotas, volatile rents in the major cities, and digital entrants competing on thinner margins. Traditional budgeting passes those increases through in silence; ZBB forces you to re-examine the basis of every line.

Example 1: software subscriptions (SaaS)

Traditional budget: 'We paid SAR 24,000 a year for software subscriptions — add 5% for inflation = SAR 25,200.' Zero-based budget: print the full subscription list. For each one ask: who actually uses it? How many times in the last 90 days? Can it be replaced with something cheaper? A common outcome: you discover half the subscriptions are dormant. New budget: SAR 11,000 — SAR 13,000 saved.

Example 2: marketing spend

Traditional budget: 'We spent SAR 60,000 on Snapchat and Google ads — make it SAR 66,000.' Zero-based budget: start from your 2026 revenue target. How many new customers do you need? What does a customer cost through each channel? Build the number from the bottom up. You may find Snapchat carries a higher acquisition cost and that you should move 40% of the budget into Google Ads and SEO — the same total, a radically different allocation.

Example 3: rent and office space

Traditional budget: 'Office rent is SAR 8,000 a month, add the expected 7% annual increase.' Zero-based budget: how many employees actually come in four days a week? How many of them genuinely need the space? Is hybrid working an option? You may land on a smaller space at SAR 5,500 — a saving of SAR 30,000 a year.

Not every company needs ZBB. It consumes management time and does not suit everyone. These are five situations where it is a smart investment:

1. Margins are eroding: revenue is flat or growing, but net profit is falling. ZBB exposes the fat that has quietly built up in operating expenses.

2. Right after a period of fast growth: you went from 10 to 40 employees in two years. The org chart has usually swollen without justification, and ZBB resets it to the right size.

3. Ahead of a funding round or a sale: investors like to see a company that has been optimised. Running ZBB before you go to market lifts the valuation.

4. A structural shift in the market: a new competitor undercutting you on price, or a regulatory change (an excise tax increase, for example), calls for rebuilding the budget rather than adjusting it.

5. A nagging sense that the company runs on autopilot: expenses renew themselves automatically every year and nobody asks why. ZBB breaks that habit.

Do not run ZBB if: your company has fewer than 3 employees, or is in its first year (there simply isn't enough data to analyse), or you are facing an immediate liquidity crisis — build a 13-week cash flow forecast first.

Step 1: define your decision units

A decision unit is a cluster of expenses under one owner who has the authority to rebuild them. Examples: 'digital marketing', 'customer service', 'general administration', 'product development'. Small companies need 5–8 units; mid-sized companies 10–15.

Step 2: tie every unit to a measurable outcome

Digital marketing → marketing qualified leads (MQLs) per month. Customer service → satisfaction score (CSAT) plus average response time. Product development → features shipped per quarter.

Step 3: build alternative decision packages for each unit

For every unit, prepare three scenarios: - Bare minimum: 60% of last year's budget. What can you still deliver? - Business as usual: 100%. The expected level of performance. - Expansion: 130%. What additional goals does the increase unlock?

Step 4: rank the packages company-wide

Every package from every unit goes into one pile and is ranked by return relative to cost. This is the decisive moment: you may choose to fund the bare minimum for customer service and the expansion package for marketing, because marketing contributes more to next quarter's revenue.

Step 5: allocate and execute

Leadership draws the line at a defined total. Every package above the line gets funded; anything below it does not. Each owner walks away knowing their new budget and the targets attached to it.

Step 6: review monthly

ZBB is not a once-a-year event you close and forget. Every month, check: does actual spend match the package that was approved? Are the results landing? Overspending without overdelivering is your signal to reopen the file.

Marketing (the easiest place to start)

Work backwards up the sales funnel. 2026 target: 480 new customers. Average conversion from MQL to paying customer = 12%. That means you need 4,000 MQLs a year. Cost per MQL by channel: - Google Ads (high intent): SAR 22/MQL × 1,800 MQLs = SAR 39,600. - SEO and content: SAR 8/MQL × 1,200 MQLs = SAR 9,600. - Snapchat and TikTok (brand awareness): SAR 35/MQL × 600 MQLs = SAR 21,000. - LinkedIn (B2B): SAR 60/MQL × 400 MQLs = SAR 24,000. Total: SAR 94,200. That number is built from the target, not from 'last year's spend plus 10%'.

Payroll (the hardest, and the highest impact)

ZBB does not mean cutting headcount at random. It means asking, for every role: what output do we expect? Does that output justify the full salary? Could it be merged with another role? Could part of it be automated?

An example: you have 4 people doing data entry at an average salary of SAR 6,500 (SAR 26,000 a month in total). The ZBB analysis shows that 60% of that data entry can be automated through OCR and integration with the Zakat, Tax and Customs Authority (ZATCA). The outcome: 2 employees plus automation (SAR 13,000 in salaries) plus a tool costing SAR 1,500 a month = SAR 14,500. A saving of SAR 11,500 a month, or SAR 138,000 a year.

Operations (rent, utilities, logistics)

Every operating line answers three questions: (1) is it essential to delivering the service? (2) can it be replaced by something cheaper at the same quality? (3) is it sized to actual volume? A warehouse lease larger than what you need for the next 6 months is budget thrown away.

Mistake 1: treating it purely as a cost-cutting exercise

ZBB is not a chopping tool. It is a reallocation tool. You may well spend the same in 2026 as you did in 2025, just on different priorities. Get this wrong and it becomes an across-the-board haircut that everyone resents and morale takes the hit.

Mistake 2: imposing it top-down without the owners

Every manager has to build their own packages. If you hand down numbers from above, everyone switches into defending their figures rather than honestly challenging them.

Mistake 3: ignoring the small line items

Electricity, maintenance, stationery, hospitality. Each is trivial on its own, but together they can account for 12–18% of total expenses. A good ZBB pass reviews all of them.

Mistake 4: running it every quarter instead of annually

A full ZBB every quarter exhausts the management team. A sensible rhythm: a full ZBB once a year, with a quarterly review focused on the lines that came in more than 15% over or under.

Mistake 5: not linking it to how managers are rewarded

A manager who hits their targets inside their budget should be rewarded for it. Without that, the incentives are broken — who would ever argue for a smaller budget of their own?

Snad supports the ZBB method through several connected capabilities:

• Budgets structured as decision units: create a budget per department, branch or product line, with its own revenue and expense lines for each unit.

• Budgets linked to cost centres: every budget maps to a specific cost centre, so actuals are compared against budget automatically.

• Automatic alerts when a package is being exceeded: when a line hits 80% or 100% of its budget, you are notified before the period closes rather than after.

• Variance reports: the gap between the zero-based budget and actuals, in both value and percentage, for every line and every unit.

• Scenario comparison: store the bare minimum, business-as-usual and expansion packages for each unit and switch between them as conditions change.

• Integration with the rest of Snad: sales, purchases, payroll, e-invoicing and inventory all feed the actuals automatically, so there is no manual data entry.

The 30-day free trial is long enough to run one full quarterly ZBB cycle and see the variances before you commit to a subscription.

Four rules for getting your first ZBB cycle right:

1. Start with one department, not the whole company: pick the one whose costs feel bloated without justification — usually marketing or general administration. Apply ZBB there first, then expand.

2. Allow 4–6 weeks for the first cycle: building decision packages takes time. Do not rush it before making final calls.

3. Tie the goals to the money, not the other way round: the golden rule is 'what does this spend deliver for the company?' If the answer isn't measurable, the budget is weak.

4. Review monthly, not just at year end: a zero-based budget left on the shelf without follow-up is no different from a traditional one. The value lives in the tracking.

A mid-sized Saudi company running ZBB for the first time typically saves 8–15% of operating expenses in year one, and redeploys a good part of that into higher-return lines. The real payoff is bigger than the number: a culture that asks 'why' before every spending decision.
