Invoices that write themselves, books that close themselves.
Finish a sale or a repair and the invoice is already made: your layout, the right tax split, a structured payment reference. Supplier invoices get read by AI, bank payments match themselves, and your accountant gets structured data instead of a shoebox.
Five moments where the paperwork usually eats your evening.
A jewelry store's invoicing is not a shoe store's invoicing. Repairs, returns on high-value pieces, gold buy-ins, quarterly tax. Here's what each one looks like with and without Gem Logic.
None of this is extra software. The invoice is born from the sale or the repair, so the numbers your accountant sees are the same numbers your counter worked with.
The boring parts of bookkeeping, removed.
These aren't add-ons you buy separately. They come with the same system your counter already uses.
Upload the PDF and OCR plus AI pull out the supplier, date, number, line amounts and tax. You confirm, it's booked, and it's linked to the supplier in your contacts.
Made from the original sale or repair, numbered in your invoice sequence, same layout as your invoices. Returned pieces go back into stock automatically.
Every product and service carries its rate. The invoice shows the breakdown per line and per rate, including margin scheme for pre-owned pieces.
Every invoice carries a Belgian structured reference and a scannable EPC/SEPA QR code. Amount, reference and account pre-filled in the customer's banking app.
Import your statements and payments are matched to open invoices by reference, or suggested by amount. Paid, overdue and partial payments in one clear list.
Add a pay-now button to emailed invoices. The customer pays by card, Bancontact or iDEAL, and the invoice marks itself as paid. Same day, not same month.

Upload the PDF. Review, don't retype.
When a supplier invoice arrives, you drop the PDF into Gem Logic. The AI reads it and fills in the fields. Your job shrinks from data entry to a quick check.
- Supplier recognised by tax number
- Amounts and tax split extracted per line
- Every invoice stored digitally and searchable
The statement checks itself against your invoices.
Import your bank statements and Gem Logic matches incoming payments to open invoices. Payments with a structured reference match automatically; the rest get suggestions based on the amount.
- Automatic matching by structured reference
- Amount-based suggestions for unstructured payments
- Open invoices with aging, partial payments tracked


Structured data in, lower accounting bills out.
Export sales and purchase journals, send invoices electronically via PEPPOL and UBL, or sync straight into Xero or Exact Online. Your accountant imports instead of retyping, and stops billing you for the sorting.
The repair is ready, and so is the way to pay for it.
Email the invoice with a pay-now link and the customer pays from the couch with card, Bancontact or iDEAL via Stripe. Ideal for repairs and custom orders where the customer isn't standing at your counter.
- Customer clicks the link in the email
- Pays with their preferred method
- Invoice marked as paid automatically
