Liven

The ultimate hospo solution

Most modern POS systems already integrate with MYOB and Xero, that’s table stakes. What actually determines whether accounting is easy or painful is the quality and consistency of the operational data feeding those systems.

When sales, tax, payments, inventory and labour all come from the same operational source, configured consistently across venues and channels, accounting becomes reliable. When they don’t, finance teams spend month-end reconciling inconsistencies that should never have existed in the first place.

Clean, Consistent Accounting Integrations (Without the Re-Coding Circus)

Accounting issues rarely come from a lack of integration. They usually come from inconsistent configuration across venues, channels and teams. Pricing, tax and surcharges may be set up slightly differently by location. Tips may be treated inconsistently. Categories drift over time. In multi-venue groups, this leads to mismatched Chart of Accounts logic and hours of manual re-coding at month-end.

What a modern POS must do:

  • Push sales, surcharges, discounts, tips, liabilities and tender types directly into MYOB/Xero/QuickBooks with zero manual cleanup.

  • Maintain a single Chart of Accounts logic across every venue and every ordering channel.

  • Prevent category drift, the silent killer of multi-venue accounting consistency.

How Liven supports this: Liven integrates with top accounting platforms like MYOB and Xero using a single mapping layer across POS, kiosk, mobile ordering, delivery, and other sales channels. This ensures:

  • Taxable vs non-taxable sales always land in the right accounting category.

  • Surcharges (bank, holiday, weekend) map consistently every time.

  • Tips, discounts and liabilities use standardised ledger codes.

  • Multi-venue groups operate on one accounting logic, not venue-by-venue variations.

With Liven, every FOH channel speaks the same accounting language, removing the primary source of reconciliation errors.

GST Accuracy & BAS-Ready Categorisation

Tax mistakes don’t come from one big mistake, they accumulate. One incorrect surcharge setup. One category misaligned across channels. One staff member incorrectly marking products as GST-free. At BAS time, inconsistencies blow up. These issues often surface only at BAS time, when correcting them is slow and risky.

What a modern POS must do: 

  • Apply GST rules consistently at the point of sale

  • Correctly classify taxable vs GST-free sales and surcharges.

  • Produce BAS-ready exports that don’t need to be cleaned up.

How Liven supports this: Liven lets you enforce tax logic upstream, so BAS becomes an export not a reconstruction.

  • Default MYOB/Xero mappings ensure GST consistency across all channels.

  • Centralised price and surcharge management prevents venue-by-venue configuration errors.

  • Product-level mapping is available for operators who need deep categorisation control.

  • Payments are mapped to correct clearing accounts (cash, EFTPOS, Tyro, etc.) automatically.

When all channels share one set of tax rules, BAS goes from “reconstruct the month” to “export and submit.”

Integrated Inventory & Real COGS (Not spreadsheet COGS)

COGS isn’t just an operational metric, it drives gross margin, menu profitability, inventory valuation and budgeting. When COGS are off, it throws off everything downstream: your margins look better than they are, inventory gets misstated, supplier cost drift goes unnoticed and variance analysis becomes guesswork. Accurate COGS is the difference between a P&L you can trust and one you have to explain. But this doesn’t come through accounting integrations alone. It comes from operational systems that track real ingredient usage, modifiers, wastage and supplier pricing.

What a modern POS must do:
Most “POS-integrated inventory systems” give operators guesstimated COGS based on ideal usage. Real COGS requires knowing what ingredients were used, what modifiers were selected, what wastage occurred, and what suppliers actually charged. So a modern POS must:

  • Track ingredient and modifier usage accurately through recipes and sub-recipes.

  • Update stock in real time as sales and wastage occur.

  • Digitise supplier invoices so actual cost prices flow into COGS.

  • Provide visibility into cost drift across suppliers and items.

How Liven supports this: This is where the Liven platform stands out.

  • Recipe-level and modifier-level mapping ties every sale to real ingredient consumption.

  • Wastage, transfers and spoilage update stock immediately.

  • Invoice digitisation (OCR + AI + human verification) turns PDFs/photos into structured AP and inventory data.

  • Automated budget alerts highlight price deviations before month-end shocks hit.

  • True COGS (TCOGS) combines actual ingredient usage with supplier pricing to surface real menu profitability.

Operators don’t just see COGS, they see true cost behaviour across ingredients, suppliers and venues. This level of accuracy is rare in POS ecosystems, and is extremely useful when it comes to accounting.

Real-Time Reporting & Any-Venue, Any-Device Visibility

Operators rely on daily and weekly numbers to guide decisions, but most dashboards give you an incomplete picture. Refunds get buried. Offers/discounting gets chaotic. Adjustments aren’t monitored. Category drift confuses the picture. Finance teams often operate on stale or inconsistent data.

What a modern POS must do: 

  • Provide live, consolidated reporting across all venues and channels.

  • Surface payment mix, surcharges, adjustments, voids and leakage clearly.

  • Use one operational dataset so finance, ops and accounting stop arguing about whose numbers are “right.”

How Liven supports this: Liven OS consolidates every channel and venue into a single reporting layer:

  • Near real-time venue and product-level insights in your pocket.

  • 40+ cross-venue, accounting-meaningful reports (sales, payments, liability balances, inventory, loyalty, adjustments).

  • Dedicated refund/adjustment reporting catches leakage the moment it appears.

  • Centralised Discount and coupon settings give HQ control and usage reports make it easy to track

  • True item-level profitability (TCOGS) exposes which products actually make money.

Most systems can show “what you sold.”  Liven shows whether selling it made you money.

Labour & Payroll That Align with Financial Reality

Labour is one of the biggest cost drivers in hospitality, but POS and payroll rarely speak the same language. Operators guess at labour-to-revenue ratios. Finance tries to align Tanda/Deputy data with POS exports.

What a modern POS must do:

  • Integrate cleanly with Tanda and Deputy.

  • Provide shift-level labour-to-revenue insights.

  • Ensure labour data sits on the same operational truth as sales.

How Liven supports this: Liven is not payroll software, but it ensures payroll sits on top of accurate operational truth. 

  • Liven integrates with Tanda and Deputy so labour data can be reconciled against sales performance. 

  • Using the staff clock/in out feature in POS helps match payroll calculations with actual shifts worked.

  •  It combines labour insights with real-time sales to show you labour-to-revenue ratios that help you understand what really happened on the floor and make better operational decisions

Transparent Cash Flow, Settlements and Audit Trails You Can Trust

Unreconciled payouts, missing settlement data, fragmented tender tracking, and unreliable terminals all create accounting noise, but the deeper issue is control. Without strong permissions, traceable audit logs and secure terminals, unauthorised refunds, discounts or tender adjustments slip through unnoticed. The result is unstable cash flow, unexplained variances and financial records finance teams can’t rely on.

What a modern POS must do: 

  • Track every tender type with precision.

  • Provide predictable settlement cycles and clean payout data.

  • Maintain clear refund, surcharge and adjustment logs.

  • Enforce tight financial controls to minimise fraud and internal leakage.

  • Sync data from trade done in offline mode

How Liven supports this: With Liven, cash flow becomes stable, not a guessing game.

  • Same-day settlements improve cash flow predictability.

  • Payments and POS operate as one ledger, eliminating reconciliation gaps.

  • Offline mode protects both trading and data integrity during network issues.

  • Centralised staff permissions control who can process refunds, apply discounts or access sensitive financial functions.

  • Dynamic surcharging protects margin with full accounting traceability.

  • Built-in security and fraud detection reduce operational risk

  • Dedicated refund and adjustment reporting surfaces leakage immediately

Invoice, Supplier & AP Integration That Closes the Loop

Invoices are often the most painful part of restaurant accounting. Data entry errors, missing documents, mismatched purchase orders, and opaque supplier pricing all undermine COGS and Accounts Paid accuracy.

What a modern POS must do: 

  • Digitise invoices quickly and accurately.

  • Push item-level costs into inventory and accounting automatically.

  • Support structured purchasing workflows (approvals, invoice matching).

How Liven supports this: 

  • Invoices are captured via a hybrid OCR + AI + human validation, reducing manual labour and errors, and improving accuracy

  • Unique 3-way matching (PO ↔ GRN ↔ Invoice) that prevents over-billing and disputes and makes reconciliation so much easier

  • Item-level data flows into inventory, COGS and accounting consistently.

  • Supplier analytics expose cost creep early.

This is full-circle financial discipline, from purchasing to plate to P&L.

Why All of This Matters

When your POS, ordering, payments and inventory all operate inside one structured operating system, accounting becomes simple, predictable and trustable. This is the real value that a modern unified POS like Liven can deliver:

  • Cleaner BAS

  • Faster month-end close

  • More accurate COGS

  • Fewer surprises

  • Stronger controls

  • Reliable multi-venue reporting

It becomes the financial backbone the whole business can trust. And yes, it makes accounting boring again. Which is exactly what good accounting should be.
