A step-by-step guide to writing an expense policy your team will actually follow
A company expense policy is a written set of rules for how your team spends company money: what’s claimable, how much they can spend, what needs approval, and how they get reimbursed. A good one covers six things: expense categories, spending limits, approval rules, receipt requirements, the reimbursement process, and a review schedule. Most Singapore SMEs can draft a working version in an afternoon, especially with a template to start from.
If your team is already paying for Stripe charges, AWS invoices, client dinners, Grab rides, and overseas supplier bills, you have expenses to manage whether or not you have a policy. Without one, you get surprise charges, receipts that show up weeks late, and a finance lead chasing people over WhatsApp. The fix is a short, clear policy plus a way to enforce it, and both are easier to set up than most founders expect.
Setting Up an Expense Policy Summary:
| Highlights | Details |
|---|---|
| What it is | A written rulebook for company spending: what’s claimable, the limits, and how to claim it back |
| Core sections | Categories, spending limits, approval rules, receipt rules, reimbursement, review cadence |
| Build time | A first version takes an afternoon; a template gets you most of the way there |
| SG must-have | Keep receipts and source documents for 5 years (IRAS record-keeping rule) |
| Make it stick | Card-level spend limits and category locks enforce the policy at the point of sale, not after |
| Skip it, and | Untracked spend, slow reimbursements, and FX markups quietly eat into margin |
An expense policy isn’t about distrust. It’s about giving your team a clear “yes” so they stop asking permission for every S$40 lunch, while your finance function keeps spend visible and books clean. More than 10,000 finance teams already run their company spends through YouBiz, and a clear policy is what turns a stack of cards into a system.

What Is a Company Expense Policy?
A company expense policy is the document that tells your team how they can spend company money and how they’ll be paid back. It sets the categories that count as business expenses, the limits on each, who signs off on what, and the paperwork everyone owes finance.
Think of it as the rulebook behind every company card and reimbursement claim. When someone asks “can I expense this?”, the policy is the answer, so the question doesn’t land on you every time. It protects the business from overspending and fraud, keeps your accounts clean for tax season, and saves your team the awkwardness of guessing.
The policy typically scales with the company. A three-person startup might run one page. A 40-person company with a travelling sales team needs categories, tiered limits, and a proper approval chain. The structure below works for both, and you decide how much detail each section carries.
Why Your Team Needs One
Without a policy, every expense becomes a one-off decision, and those decisions pile up. You end up approving spends after the money’s gone, reconciling mystery charges at month-end, and reimbursing people slowly enough that they resent it.
A clear policy fixes the three things that hurt most:
- Overspending. Limits and category rules stop a S$500 “client dinner” from becoming a norm nobody agreed to.
- Slow reimbursements. A defined submission and approval flow means people get paid back in days, not weeks.
- Messy books. Consistent categories and receipt rules give your accountant clean data, which matters when IRAS expects source documents kept for five years.
FX is another cost SG businesses feel more than most. If your team spends abroad or pays overseas suppliers, the standard bank foreign transaction fee runs to about 3.25%. On S$10,000 of monthly overseas spend, that’s roughly S$325 gone before anyone reviews a single line. A policy that routes that spend onto a 0% FX card keeps the cost where it belongs.

What to Include in an Expense Policy
Every workable expense policy answers six questions. Get these down and you have a policy; everything else is nice-to-have.
- What’s a business expense? The categories you’ll reimburse (travel, software, meals, office supplies) and the ones you won’t.
- How much can people spend? Overall limits, per-category caps, and any per-transaction thresholds.
- What needs approval first? The line above which someone has to sign off before the money moves.
- What proof do you need? Receipt rules: when one’s required, what counts, and by when.
- How do people get paid back? Company card, reimbursement claim, or both, and the timeline for each.
- When do you review it? How often you revisit limits and categories as the business changes.
Keep the language plain. A policy nobody reads because it’s written like a legal contract is worse than a short one people actually follow.
How to Write an Expense Policy, Step by Step
Here’s how to build each section, in order. Work through them once and you’ll have a first draft by the end of the day.
Step 1: Define your expense categories
Start by listing what the company will and won’t pay for. Clear categories are the backbone of the whole policy. They drive your limits, your approval rules, and how clean your books look later.
Common reimbursable categories for a Singapore SME:
- Travel: flights, hotels, ground transport, overseas per-diems
- Meals and entertainment: client meetings, team meals, staff welfare
- Software and subscriptions: SaaS tools, cloud hosting, domain and licence fees
- Office and equipment: supplies, hardware, co-working desks
- Marketing: ad spend, events, sponsored content
- Professional services: legal, accounting, contractors
Spell out the common exclusions too, so nobody has to ask: personal purchases, alcohol beyond a set limit, fines, and anything without a receipt. The clearer the list, the fewer grey-area claims land on finance.
Step 2: Set spending limits
Attach a limit to each category so people know their ceiling without asking. Limits do two jobs: they cap risk, and they hand your team a standing “yes” for anything underneath.
Three types of limit worth setting:
- Per-transaction caps: the most a single purchase can be (e.g. S$200 for a team meal)
- Monthly limits: a rolling budget per person or per department
- Category caps: a ceiling on a whole category, like S$2,000/month on software
Set limits that match how each role actually spends. A salesperson who entertains clients needs more meal budget than an engineer; a marketing lead needs real ad-spend headroom. Tiering by role or seniority beats one blanket number for everyone.
Step 3: Decide what needs pre-approval
Draw a clear line between spend people can just make and spend that needs a yes first. This is where you balance speed against control. Approve too much, and you’re the bottleneck; approve too little and surprises slip through.
A simple, common setup:
- Under S$100: no approval, just a receipt
- S$100–S$1,000: manager approval
- Above S$1,000: manager plus finance sign-off
Also flag specific items that always need pre-approval regardless of amount: new software subscriptions, travel bookings, or anything recurring, since those quietly compound month after month.
Step 4: Set your receipt and documentation rules
Decide when a receipt is required, what qualifies, and the deadline to submit it. This is the part that saves you at tax time, so it’s worth being specific.
A practical standard:
- Receipts required for anything above a small threshold (say S$20)
- The receipt must show the merchant, date, amount, and what was bought
- Submitted within 7 days of the spend, or by month-end at the latest
For Singapore companies this isn’t just admin hygiene. IRAS requires businesses to keep source documents, such as receipts, invoices, and vouchers, for at least five years from the relevant Year of Assessment to support what you claim. A policy that captures receipts as spend happens means you’re never reconstructing a paper trail two years later.
Step 5: Choose how people pay and get reimbursed
Decide how money actually leaves the company. There are two models, and most teams end up using both.
- Company cards. Team members spend on a business card, so there’s nothing to reimburse and every transaction lands in one place. Best for regular or larger spend.
- Out-of-pocket claims. Someone pays personally and submits a claim to be paid back. Fine for the occasional one-off, painful as a default.
Cards win for anything recurring because the spend is visible in real time and reconciliation is automatic. Reserve reimbursements for genuine exceptions, and set a clear payout timeline (say, with the next payroll run) so people aren’t out of pocket for long.
Step 6: Map the submission and approval workflow
Write down the exact path an expense takes, from spend to sign-off to paid. When the workflow is clear, nothing stalls in someone’s inbox.
A standard flow:
- Employee makes the spend (or submits a claim)
- Receipt and any notes get attached
- It routes to the approver based on the amount
- Approver reviews and approves or queries
- Finance reconciles and, for claims, pays out
The fastest workflows are automated, where the routing and notifications happen without anyone chasing. The slowest are the ones that live in email and spreadsheets.
Step 7: Set a review cadence
Put a date in the calendar to revisit the policy. Limits that made sense at ten people feel wrong at thirty, and new spend categories appear as the business grows.
A quarterly light-touch check plus one proper annual review is enough for most SMEs. Look at what got flagged, what limits people kept bumping into, and which categories need adding or cutting. A policy is a living document, not a one-time write-up.
How to Categorise Team Expenses
Group expenses by their business purpose, not by who spent the money. Purpose-based categories are what make your reports readable and your tax filing defensible.
The cleanest approach is to map each category to how you’ll treat it at year-end. Travel, software, and office supplies are usually straightforward operating costs.
Meals and entertainment need a bit more care. Split client entertainment (taking a customer out) from staff welfare (a team lunch or a company D&D), since the two can be treated differently for tax. IRAS looks at whether the cost was wholly and exclusively incurred to earn income.
For team-building and staff-welfare spend specifically:
- Keep it in its own category rather than lumping it under “meals”, so the intent stays obvious
- Note the occasion on the receipt (team offsite, festive celebration, work anniversary)
- Watch the line between staff welfare and a personal perk, because that’s what determines deductibility
The tighter your categories, the less your accountant has to interpret, and the fewer questions come back at filing time.

How to Enforce Your Policy Automatically
A policy on paper only works if people remember it. The version that actually holds is one built into the cards your team spends on, so the rules apply at the point of sale instead of in a month-end review. That’s where YouBiz comes in.
Give each person their own card instead of sharing one. Virtual corporate cards are ready in the app the moment you create them, and physical cards arrive in 5–7 business days. Then wire your written rules straight into each card:
- Spending limits per card. Set a monthly limit that matches the policy cap for that role, and adjust it any time. Nobody can spend past their ceiling.
- Category locks. Restrict a card to the merchant categories it should touch, like travel or software. Anything outside those categories is automatically declined, so your “not covered” list stops being a suggestion.
- Approval policies. Route each transaction through one or two approval steps, assigned to the roles or people you choose. Approvers can review and clear requests from their phone, so nothing stalls.
- Real-time tracking and receipts. Every transaction shows up instantly. Team members snap and upload receipts, add notes, and tag spend on the go, so the paper trail is done as the money moves, not chased later.
- Clean export. Push transaction data to Xero, QuickBooks, or NetSuite in a pre-formatted file, so reconciliation is a review rather than a rebuild.
On top of the controls, spend on YouBiz earns unlimited 1% cashback on eligible spends with no cap, at 0% FX fees across 150+ currencies, on an account with S$0 monthly fees. The policy keeps spend in line; the card makes that spend cheaper.

Common Mistakes to Avoid
Most expense policies fail the same few ways. Sidestep these and yours will hold.
- Writing it and forgetting it. A policy nobody revisits drifts out of date within a year. Set the review cadence.
- Limits that don’t match reality. Caps set too low get ignored; set too high, they don’t protect anything. Base them on how each role actually spends.
- Making it too long. A 15-page document reads like a contract and gets skimmed. Keep it to what people need to know.
- Relying on trust alone. Good intentions don’t stop out-of-policy spending. Build the rules into the cards so they enforce themselves.
- Skipping the receipt discipline. No receipts means no clean books and no IRAS trail. Capture them as spend happens.
FAQs
Start with six sections: expense categories, spending limits, approval rules, receipt requirements, the reimbursement process, and a review schedule. Fill each one in plain language, use a template to speed it up, and keep the whole thing short enough that people actually read it. Most SMEs can draft a working version in an afternoon.
The essentials are what counts as a business expense, how much people can spend, what needs approval first, what documentation you require, how reimbursement works, and how often you review the policy. Anything beyond that is detail you add as the team grows.
Keep team-building and staff-welfare spend in its own category rather than under general “meals”, and note the occasion on the receipt. That separation matters for tax, since IRAS treats staff welfare differently from client entertainment and looks at whether the cost was wholly and exclusively incurred to earn income.
At least five years from the relevant Year of Assessment. IRAS requires businesses to keep source documents, such as receipts, invoices, and vouchers, to support the expenses they claim, so build that retention into your policy from day one.
The reliable way is to enforce limits at the card level rather than after the fact. With YouBiz, you set a monthly spending limit and lock merchant categories on each card, so out-of-policy spend is declined at the point of sale instead of showing up in a month-end review.
Yes, even at a few employees. The moment more than one employee spends company money, you need a shared answer to “can I expense this?”. A short policy prevents the untracked spend and slow reimbursements that get expensive as you grow.
Turn Your Policy Into a System That Runs Itself
A written policy tells your team the rules. The cards they spend on are what make the rules stick: spending limits that match each role, category locks that decline out-of-policy spend, approvals that route by amount, and receipts captured as the money moves. That’s the difference between a document in a shared drive and a system that keeps spending clean on its own.
YouBiz gives you all of it on one account: free physical and virtual cards with per-card controls, real-time tracking, and export to your accounting software, plus unlimited 1% cashback on eligible spends and 0% FX fees on overseas spend, with no monthly fee.
Sign up at you.co/biz in under 5 minutes via Singpass. Approval typically takes 1–2 business days, your virtual Mastercard is live in the app right after, and physical cards follow in 5–7 working days.
