Saturday's card takings
Priya Sharma, operations manager at Acme Ltd's café, asked what the till took on Saturday. Memtro listed Saturday's card transactions with totals per currency and picked out two refunds by time and amount.
SumUp + Memtro
What did we take on the card reader, and what reached the bank?
SumUp connects Memtro to your card takings. It reads transactions with time, type, status, amount, payment type and card brand, payouts to your bank with fees deducted, and your merchant profile. Card numbers, staff emails and bank details are never returned. When asked, and once an administrator has granted the action by name, it refunds transactions, creates and deactivates online checkouts, sends an amount to a card reader, saves customers, renames or removes readers and invites or removes team members. A refund moves money back to the cardholder and is permanent. An invitation emails the person.
In Memtro
What you can do with SumUp in Memtro
Ask in plain English from chat, your editor, a scheduled job or your own agent. The model picks the right SumUp tool, reads what it needs, and answers with the source cited.
What it does
- 01Lists card transactions with code, time, type (payment, refund, chargeback), status, amount, currency, payment type and card brand
- 02Totals takings per currency over what it returns, covering the last 7 days unless you name a period
- 03Lists payouts to your bank and the deductions against them, with date, amount, fee, status and reference, linked to each transaction
- 04Reads the merchant profile: business name, business type, country, default currency, locale, website and whether it is a sandbox
- 05When asked and granted, refunds a transaction in full or in part, which moves money to the cardholder and cannot be reversed, creates or deactivates an online checkout, and sends an amount to a card reader for the customer to pay
- 06When asked and granted, saves or edits customer records, renames or removes a card reader, and invites a person by email or removes a team member
Acts when asked
When you ask it to
These tools change something in SumUp. The model is told to use them only when you ask for exactly that, and an administrator grants each one by name to the teams that may use it; a personal connection acts only after its owner allows it.
- 01Refund a card transaction, in full or in part (moves money back to the cardholder, permanent)
- 02Create an online checkout for an amount, optionally with a SumUp payment page link
- 03Deactivate an unpaid checkout so it can no longer be paid (permanent)
- 04Send an amount to a card reader for the customer to pay (takes a payment if they do)
- 05Stop the payment showing on a card reader
- 06Save a customer record
- 07Edit a saved customer's details
- 08Rename a card reader
- 09Remove a card reader from the account (permanent until it is paired again)
- 10Invite a person to the SumUp account with named roles (emails them)
- 11Remove a team member from the SumUp account
In practice
Ask it like you would a colleague
Once SumUp is connected, these are the kinds of things people ask. Plain questions, no syntax. If the answer lives partly in another system you have connected, Memtro looks there too.
SumUp + Memtro
What did we take on Saturday?
Any refunds this week?
How much did SumUp take in fees on last month's payouts?
Were there any chargebacks this month?
Refund £4.50 of this morning's 9:14 transaction, the oat milk was missing.
A partial refund
Tom Reilly, café manager at Northwind, asked Memtro to refund £3 of a customer's order after a missing item. Memtro found the transaction by time and amount and refunded £3 to the customer's card. SumUp moved the money from the merchant balance, and the refund cannot be reversed.

FAQ
Questions
Can Memtro change anything in SumUp?+
Only when you ask, and only what it has been granted: refund a card transaction, in full or in part (moves money back to the cardholder, permanent); create an online checkout for an amount, optionally with a SumUp payment page link; deactivate an unpaid checkout so it can no longer be paid (permanent); send an amount to a card reader for the customer to pay (takes a payment if they do); stop the payment showing on a card reader; save a customer record; edit a saved customer's details; rename a card reader; remove a card reader from the account (permanent until it is paired again); invite a person to the SumUp account with named roles (emails them); remove a team member from the SumUp account. Every other tool reads, searches or lists. The Connections page labels the tools that act, an administrator grants each one by name to the teams that may use it, and a personal connection acts only after its owner allows it.
Who can use a SumUp connection?+
A personal connection serves only your own requests. A shared connection serves the organisation: everyone, or only the teams an admin chooses. Admins can always add shared connections; other members need the permission.
Does Memtro store my SumUp data?+
Credentials are encrypted at rest. Tool results are cached briefly so agent loops do not repeat identical calls, and the facts the model extracts are saved to your organisation's memory with provenance (system, record and link) so they can be checked and superseded. An hourly sync anchors recently changed SumUp records into memory as entities.
How do I connect SumUp?+
Secret API key and merchant code. Sign in at me.sumup.com and open Settings → For Developers → Toolkit → API Keys.
