Detailed Comparison

Integration Scope

Merchant-Scoped (Square, Lightspeed, MplusKassa)

• One connection covers all locations
• Locations are imported automatically from the POS system
• After import, complete missing location fields (address, coordinates, timezone)
• Ideal when the POS is the source of truth for business structure

Connect POS account (merchant level)
    |
    v
POS branches imported as Upvendo locations
    |
    v
Menu items synced across all locations
    |
    v
Orders from any Upvendo channel pushed to correct POS location

Location-Specific (Kassanet/Hendrickx/Vanhoutte, Shopcaisse)

• Each location must be connected separately
• Locations must be created manually in Upvendo first
• Select the target location from the topbar before connecting
• Ideal when different locations use different POS systems or configurations

Create location manually in Upvendo
    |
    v
Select location from topbar
    |
    v
Navigate to In-House > Settings
    |
    v
Enter POS credentials for that location
    |
    v
Menu imported for that location only

Payment Handling

Integration	Payment Provider	What This Means
Square	Square Payments (included)	No separate payment setup needed. Square handles online + terminal payments. Replaces Stripe and Viva Wallet.
Lightspeed	Requires Stripe and/or Viva Wallet	Must set up Stripe (online) and/or Viva Wallet (terminal) independently. Lightspeed handles POS-side payments only.
MplusKassa	Requires Stripe and/or Viva Wallet	Same as Lightspeed. MplusKassa can relay external payment events via webhooks.
Kassanet	Requires Stripe and/or Viva Wallet	POS handles in-store payments. Upvendo channels need their own payment provider.
Shopcaisse	Requires Stripe and/or Viva Wallet	Orders pushed to POS only after payment confirmed in Upvendo.

Key Insight: Only Square bundles payment processing. All other integrations require a separate payment provider (Stripe for online, Viva Wallet for terminals).

Migration Considerations

Switching POS Integrations

• Disconnect the current integration before connecting a new one
• Menu items from the old integration remain in Upvendo
• You may need to re-map or clean up duplicate items
• Order history is preserved regardless of integration changes

Adding Square to an Existing Setup

• Square replaces Stripe and Viva Wallet for payments
• Existing Stripe/Viva Wallet configurations become inactive
• If you disconnect Square later, you must re-enable Stripe/Viva Wallet manually

Multiple Locations with Different POS Systems

• Merchant-scoped integrations apply to all locations
• Location-specific integrations can be mixed (e.g., Location A uses Hendrickx, Location B uses Vanhoutte)
• You cannot have two merchant-scoped POS integrations active simultaneously
