Chasing what is owed
Before the Friday cash call the finance lead asks which customer invoices are unpaid. Memtro lists eleven with the amount outstanding on each and a total per currency, and notes that two from Acme are past their deadline.
Pennylane + Memtro
Ask which Pennylane customer invoices are unpaid, and what is outstanding to each supplier.
Connect Pennylane with a company API token and Memtro reads customer and supplier invoices with deadline, payment status and amount outstanding, quotes, customers and suppliers, bank transactions and the trial balance. Bank details, IBANs, phone numbers and addresses are not returned. The hourly sync writes changed invoices into memory. When you ask, and once an administrator has granted the action by name, it can create and update customers and suppliers, draft quotes and invoices, and mark invoices paid, which moves no money. Finalising an invoice is permanent, and emailing an invoice or quote reaches the customer and cannot be recalled.
In Memtro
What you can do with Pennylane in Memtro
Ask in plain English from chat, your editor, a scheduled job or your own agent. The model picks the right Pennylane tool, reads what it needs, and answers with the source cited.
What it does
- 01Customer invoices and credit notes by date range or customer, with status, amount outstanding and totals per currency
- 02Supplier invoices by date range, supplier or payment status, with deadline and accounting status
- 03Customers, suppliers and quotes, with emails, VAT and registration numbers, plus bank transactions with label and amount
- 04The trial balance for a period: each ledger account's total debits and credits
- 05When asked and granted, creates or updates customers, contacts and suppliers, creates quotes and draft invoices, records manual bank transactions and marks invoices paid or validated, none of which moves money
- 06When asked and granted, finalises an invoice, which gives it its legal number for good, emails an invoice or quote to the customer, which cannot be recalled, and deletes draft invoices
Acts when asked
When you ask it to
These tools change something in Pennylane. 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.

Events
When it happens
Turn events on in the connection's Events tab on the Connections page, choose the kinds you want, and Memtro registers its address with Pennylane for you. Each event can start a job, with the event as its input. Pennylane signs every delivery, and one whose signature does not check out is refused before it is read.
Events and webhooks- 01A customer invoice's e-invoicing (PDP) status changed
- 02A supplier invoice arrived through e-invoicing
- 03A file was added to the document store (DMS)
In practice
Ask it like you would a colleague
Once Pennylane 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.
Pennylane + MemtroWhich customer invoices are unpaid, and how much is outstanding?
What do we still owe Northwind on supplier invoices?
What is the balance of account 401 at the end of September?
Turn the accepted Acme quote into an invoice and finalise it
Create a supplier called Brightwave Ltd
From quote to invoice
Camille Martin says Acme accepted last week's quote. Memtro marks the quote accepted, creates a draft invoice from it and, once Camille confirms, finalises it so it takes its legal number, then emails it to Acme's invoice recipients from Pennylane.

FAQ
Questions
Can Memtro change anything in Pennylane?+
Only when you ask, and only what it has been granted: create a company customer; create a supplier; update a customer's details; update a supplier's details; add a contact to a customer; create a draft customer invoice; finalize a draft customer invoice (numbered, can no longer be edited); email a customer invoice to the customer; mark a customer invoice paid; delete a draft customer invoice (permanent); create a draft invoice from a quote; create a quote; email a quote to the customer; set a quote's status; mark a supplier invoice paid or to be paid; validate a supplier invoice's accounting; record a bank transaction. 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 Pennylane 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 Pennylane 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 Pennylane records into memory as entities.
How do I connect Pennylane?+
Company API token. Pennylane's API needs the Essential plan or higher and an Executive, Internal Accountant or External Accountant role. The Starter plan has no Developers tab.
Can Pennylane start a job?+
Yes. Turn events on in the connection's Events tab on the Connections page, choose the kinds you want, and Memtro registers its address with Pennylane for you. A job set to start "When an event arrives" then runs once for each matching event, with the event as its input. The run treats the event as outside data, never as instructions, and anything the run remembers is kept as unverified.
