SumUp

Overview

SumUp is a card payment provider used by small businesses across the UK. Tilly integrates with SumUp to pull your transaction history and give you insights into your sales performance.

Unlike Square and Clover (which are full point-of-sale systems), SumUp is primarily a card terminal provider. This means Tilly can read transaction-level data but item-level and category data are only available when your SumUp setup includes them in the transaction record.

What Tilly can access

When you connect SumUp, Tilly requests read-only access to:

• Transaction history: all completed transactions including amounts, payment types and timestamps
• Merchant profile: your merchant code and business name

Tilly never modifies your SumUp account. All access is read-only.

How to connect

What you will see in Tilly

Once connected, your sales dashboard will show:

• Total sales and transaction count for any date range
• Average transaction value and trends
• Sales by hour so you can identify your peak trading times
• Payment method breakdown covering card types and payment methods
• Refunds tracked from transaction events
• Tips if included in transaction data

Troubleshooting

Connection failed

If you see "Failed to complete authorisation":

1. Make sure you are signing in with the correct SumUp account
2. Check that your SumUp account is active
3. Try clearing your browser cookies for SumUp and reconnecting

Token expired

SumUp access tokens are short-lived. Tilly automatically refreshes them, but if a refresh fails you may need to reconnect:

2. Click Disconnect next to SumUp
3. Click Connect SumUp again to reauthorise

Missing transaction data

• Only completed transactions are imported
• Very recent transactions may take a few minutes to appear
• Item-level detail is only available when your SumUp setup includes it in the transaction data

Disconnecting

Tilly connects to your live SumUp account using OAuth 2.0 with token refresh. If a refresh fails, go to Settings then Connections, click Disconnect next to SumUp and reconnect.
