A Consistent, Reliable Tax Workflow
Releventful includes a built-in tax engine designed specifically for event-based businesses. All pricing, GST/VAT calculations, inclusive or exclusive logic, and invoice totals are calculated within Releventful first.
When invoices sync to Xero or QuickBooks, the accounting platform records the final, approved totals exactly as issued to your client.
This approach ensures:
Your proposals, contracts, BEOs, and invoices always align
Clients are billed precisely what was approved
There are no discrepancies between systems
You maintain one consistent source of truth for tax
Releventful as Your Tax Authority
All tax calculations originate in Releventful, including:
Line item tax logic
Inclusive and exclusive tax handling
Service charges and additional fees
Final invoice totals
By calculating tax once — and only once — Releventful ensures complete consistency across all client-facing documents.
How Invoices Sync to Xero & QuickBooks
Line Items
When line items are sent to your accounting platform:
They are marked as non-taxable
This preserves the exact totals calculated in Releventful
It prevents the accounting platform from recalculating tax differently
Your accounting system then records the finalized invoice values exactly as they were issued.
If Your Pricing Is GST/VAT Exclusive
For exclusive pricing:
Releventful calculates the tax total separately
That calculated tax amount is synced as its own line item
The final invoice total matches perfectly across both systems
If Your Pricing Is GST/VAT Inclusive
For inclusive pricing:
Releventful calculates and embeds the tax within line totals
The accounting system receives the final totals as issued
No additional adjustments are required
Best Practice for a Smooth Workflow
To maintain consistency between Releventful and your accounting platform:
Allow Releventful to manage all tax calculations
Let Xero or QuickBooks record the finalized invoice totals exactly as synced
This ensures that what your client sees, what Releventful records, and what your accounting system reflects all remain perfectly aligned.
⚠ Important
Because Releventful has already calculated tax before the invoice syncs:
If additional tax is applied or recalculated inside Xero or QuickBooks after syncing, it will change the invoice totals and create discrepancies between:
The amount billed to your client
The totals shown in Releventful
The totals recorded in your accounting platform
For this reason, we recommend allowing the synced invoice values to remain unchanged in your accounting system to preserve accuracy and consistency.
Why This Design Works So Well for Event Businesses
Event pricing often includes:
Packages
Add-ons
Guest-based pricing
Tiered tax handling
Inclusive and exclusive configurations
By centralizing tax calculation inside Releventful, your operational documents (proposals, contracts, BEOs) always stay aligned with your invoices — without relying on multiple systems to interpret tax rules differently.
In Summary
Releventful calculates all tax.
Your accounting platform records the finalized totals.
Invoice amounts remain consistent across systems.
Client-facing documents and accounting records stay aligned.
