What Well does with your Pennylane connection

Connect

Connect Pennylane over OAuth (MCP DCR via Well): Well registers a client through Pennylane's OAuth Dynamic Client Registration and you approve on Pennylane's side, so the password never reaches Well; Well holds only a scoped token it can refresh.

Sync

Well brings journal entry, ledger account, and supplier in from Pennylane on live events backed by periodic reconciliation reads. The first sync backfills history in the background and the connection stays live after.

Enrich

Well resolves each Pennylane entity into ledger record, category, and vendor, assigns categories, and links every record to an audit trail across the rest of your connected tools.

Available

Your data from Pennylane lands as ledger record, category, and vendor you can search, chart, and automate, and approved records flow back to Pennylane once they clear your review queue.

    Map your entities

    Well reads invoices, journal entries, ledger accounts, transactions, and the companies and people behind them through the MCP server, mapping each into your workspace so accounting data is queryable next to the rest of your tools.

    Use the data

    Outbound, Well forwards extracted invoice PDFs to Pennylane's supplier and collections inboxes, where Pennylane's OCR creates the invoice with vendor, amount, and VAT pre-filled. Direct journal posting over the API is roadmap; Pennylane stays the system of record for entries.

    • First syncstarts as soon as connect completes

The MCP handshake finishes in about a minute. Existing accounting data reads on connect; forwarded invoices reach Pennylane's inbox as they clear extraction. Pennylane developer docs.

How Pennylane stays secure with Well

Pennylane reads through Well's hosted MCP server using OAuth Dynamic Client Registration, so Well holds no static Pennylane key, and documents go out through Pennylane's inbound email addresses. The MCP grant is read-only over your invoices, entries, and ledger; the email-in path creates invoices through Pennylane's OCR. Posting journal entries directly over the API is a roadmap item, so the token Well holds reads but does not book.

Frequently asked questions about Pennylane and Well

Two things. Reading in, Well pulls Pennylane invoices, journal entries, ledger accounts, transactions, and the companies and people behind them through Well's hosted Pennylane MCP server, so your accounting data is queryable alongside the rest of your stack. Sending out, Well forwards extracted invoice PDFs to Pennylane's inbound email addresses, where Pennylane's OCR creates the invoice with vendor, amount, VAT, and date pre-filled.

Not today. Well reads your existing journal entries and ledger structure over the MCP server, and it delivers invoice PDFs to Pennylane's email-in addresses, but writing an accounting entry directly through Pennylane's API is on the roadmap rather than shipped. So Well can read the ledger and feed invoices in, while recording entries stays with Pennylane and your accountant.

Well forwards each extracted invoice PDF to one of Pennylane's two inbound addresses: the supplier inbox for purchases, where Pennylane's OCR creates a supplier invoice, and the collections address for customer invoices. The source document stays attached to whatever Pennylane creates. Your accountant reviews a populated invoice instead of keying it in from scratch.

Because Well reads invoices, journal entries, ledger accounts, and transactions over the MCP server, you can query your accounting state in conversation: which invoices lack a matching entry, the VAT position for a period, the suppliers paid most this year. The ledger structure Pennylane holds comes across so categories and accounts line up; Pennylane stays the system of record for posted entries.

Well reads Pennylane over the MCP connection in the background and updates the workspace as records change on the Pennylane side, with the first connect bringing in your existing invoices, accounts, and entries. Forwarded invoice PDFs reach Pennylane's inbox shortly after Well extracts them. Querying works on what has already synced while the rest catches up.

Disconnecting Pennylane in Well drops the MCP read token, so Well stops reading your invoices, entries, and ledger, and it stops forwarding documents to Pennylane's inboxes. There is nothing Well wrote to the ledger to unwind, since Well only reads it. The accounting records Well mirrored stay queryable in your workspace, and everything in Pennylane stays in Pennylane.
